Colorado Volunteers Needed to Measure Rainfall in Their Backyards

CoCoRaHS, the Community Collaborative Rain, Hail and Snow Network, is celebrating its 10th year anniversary with a campaign to find 500 additional volunteers this year.

Started in 1998 as a result of the 1997 Fort Collins flash flood, the network now has more than 10,000 observers across 33 states. State residents of all ages are measuring rainfall in their own yards, which is making a difference in providing accurate precipitation information to area weather scientists.

For more information or to register as a volunteer, go to CoCoRahs.

"We desperately need help measuring rainfall across Colorado - it's fun, easy, and only takes a few minutes," said Henry Reges, CoCoRaHS national coordinator at Colorado State University. "Once you get started and see your rainfall amounts on the CoCoRaHS website, you'll realize how practical and useful the project is. CoCoRaHS data are being used by a wide range of organizations - the National Weather Service, engineers, teachers, research scientists and many more.

"Our observations can make a difference and could even help save lives by giving forecasters advanced warnings of developing flash floods," Reges added. "We've even seen mosquito control units use CoCoRaHS to estimate where the pooling of water may contribute to West Nile virus outbreaks. Each volunteer observer is like a pixel on a photo. The more pixels, the sharper the picture of rainfall that has fallen."

"It is amazing to see how much rainfall varies across our communities, which is why this task is so important," said Nolan Doesken, state climatologist at Colorado State University who founded the CoCoRaHS program. "The more observers we have, the better data we'll have for studying storms, tracking drought, monitoring water supplies and assessing crop conditions."

Anyone with an interest in weather and access to the Internet can sign up. The only equipment needed is a 4-inch diameter, high-capacity rain gauge available from the network for $22 plus shipping.

Training for new volunteers is available online. Volunteers are asked to read rain gauges each morning and upload measurements to the CoCoRAHS website.

"We need as many rain gauges as possible in backyards all around Colorado to help map Colorado rain patterns," Doesken said. "Precipitation here is precious, and the mountains cause even more variability. Knowing more about our rainfall patterns is really helpful."

One local volunteer says that it's a great motivator to get her retired husband up out of bed each morning. Additionally, CoCoRaHS can be a practical home schooling activity. There have always been Coloradoans who love weather and have been measuring precipitation for years. CoCoRaHS provides a repository for weather lovers to share their observations with others.

Severe weather can strike during just about every single afternoon and evening in Colorado during the summer months. Sometimes we can even get a surprise storm in the morning. Early today, a line of severe thunderstorms rumbled across Elbert County, prompting some warnings around 8 to 9 AM. The Windsor Tornado struck just before lunchtime, also a rather unexpected time for severe storms in our state. The Windsor storm has been officially rated as an EF 3 by the National Weather Service, unusually strong for a tornado so close to the mountains. This powerful storm has been studied by the experts and there is now an excellent summary of the path and the damage available at the following website http://www.crh.noaa.gov/crnews/display_story.php?wfo=bou&storyid=14849&source=0

With our often stormy and sometimes surprising weather, your best protection is early warning. The 24/7 Weather team, King Soopers, Regent Communications and Midland Radio Company have teamed up to help Colorado families stay safe when severe weather hits. The 24/7 Weather Alert Radios are now available at all Front Range King Soopers stores for the discounted price of $29.99. This price represents a near 50% discount from the normal retail cost. The 24/7 Weather Alert Radios will let you know when the National Weather Service sends out an emergency alert signal for tornadoes, large hail, flash floods, wildfire or dangerous winter storms. These broadcasts provide important information on any weather danger or civil emergencies. You can program your radio to received alerts and warnings for up to six different counties around the area. This powerful radio will make sure that you are informed with the most up-to-date information available.

The radios can be programmed to work anywhere in the nation, so get one for your car, RV or for friends and relatives around the country. The radios are easy to set up and have a battery back up for when the power goes out. Think of the 24/7Weather Alert Radio as the equivalent of a smoke alarm or carbon monoxide detector - every home, school and business should have one.

The demand for the radios has already been huge! Several area King Soopers stores ran out of radios over the past weekend. King Soopers and Midland Radio have secured many more radios for Colorado. If your local King Soopers is out, they will be re-supplied within a day or two. This special low-cost radio offer will be extended through Labor Day. We will keep them in stock, or have them back in a local King Soopers within a day or two. As you might imagine, with all of the severe weather across the nation, the supply of weather alert radios has been stretched thin. Through the efforts of 7News, King Sooper, Regent Broadcasting and Midland Radio, we have secured these radios for Colorado. If you live in an area that does not have a King Soopers, or if your local King Soopers does not have them in stock, you can order a 24/7 Weather Alert Radio direct from the manufacturer for the same low price of $29.95. Here is the link to order your radio on-line http://www.petra.com/scart/scart.php?referrer=kmgh

Again, we will continue to offer this special price for the 24/7 Weather Alert Radios through early September. Keep in mind, these radios work anywhere in the country, so you may want to buy one for a friend or family member in another state. It might be a great idea to get one to take along in the RV, your boat or on a camping trip. This is such an important safety device - every home, pre-school, school, place of worship or business should have a 24/7 Weather Alert Radio. These radios will also relay any civil defense warnings and are recommended by the Department of Homeland Security.

June 10 2008 Our next chance for thunderstorms and showers arrives with a cold front tomorrow. This front will move across the state during the early afternoon bringing cooler temperatures and scattered showers and thunderstorms. The cold front is bringing in a drier air mass with low realtive humidities. Showers and storms will be short lived and will not produce as much moisture as we have seen with the storms and showers from last week. Some areas at higher elevations may see some snow showers early tomorrow morning as overnight temperatures drop into the 30s.

The unsettled weather will continue into Thursday, with a chance of thunderstorms and showers. For Friday and Saturday Colorado will see much drier and warmer weather. Temperatures will rebound back into the 80s with mild overnight lows in the 50s. Before the weekend ends another chance for thunderstorm activity comes back into the forecast for Sunday. Stay tuned to 7News and thedenverchannel.com for updates on the moisture making its way into the state.

I want to alert you to a special program that will begin later this week across the Front Range. The best way to protect yourself and your family from severe thunderstorms and tornadoes is by getting the weather warnings as quickly as possible. Later this week, I will annouce a major new campaign that will help get these vital severe weather alerts to you at home, school or office. Stay tuned to 7News and TheDenverChannel.com for an important announcement coming this week!

June 9 2008 It has been an unbelievable severe weather season so far across the nation. Over the weekend, another round of severe weather brought tornadoes, large hail and flooding rains from the Great Lakes to the Ohio Valley to the plains of Texas. Over 65 twisters spun across the country Saturday and Sunday, with nearly 200 reports of large hail. Serious flooding continues in Wisconsin and Indiana as many areas had over a half foot of rain from weekend severe storms.

The threat of severe weather will continue today in the mid-Mississippi Valley as strong thunderstorms will be likely in Missouri and Illinois. Back in Colorado, we will get a break from the stormy weather as sunny skies, warm and dry conditions are expected. The temperatures today will warm into the 75-80 degree range at lower elevations, with 60s expected in the mountains. Tuesday will be windy, warm and dry as highs climb into the 80s to near 90 at lower elevations, with 70s in the mountains.

Our next thunderstorm concern arrives with a cold front on Wednesday. This front will slide into the state during the afternoon and will bring scattered showers and thunderstorms. The unsettled weather will continue on Thursday, with a good chance of thunderstorms. The drier and warmer weather will return in time for the weekend as skies clear and the temperatures bounce back into the 80s.

June 6,7,8 2008 The cool wet weather was all thanks to a cold front that moved through Colorado on Thursday. This front also helped produce some strong storms along the eastern plains. In the metro area, there were spotty showers throughout the day on Thursday. Some locations received between 1-2 inchs of rainfall over the last 24 hours. 1.93" of rain has fallen in Ft. Collins, 1.80" in Estes Park, 1.75" in Hoyt, 1.57" in Brush, 1.00" in Longmont, and 0.97" in Golden. A snow advisory remained in effect until 6:00 pm on Thursday for locations with elevations about 9,000 ft. Some mountian areas received between 2-5 inches of snow.

This wet weather pattern will move out for the weekend ahead and leave us with drier and warmer weather. Expect temperatures to heat into the upper 70s, low 80s during the day and low 50s overnight. The wild weather won't stay away for long. By Saturday afternoon another cold front will dip into the state. This cold front will increase the clouds and bring a chance for thunderstorms. Sunday will bring cooler temperatures and rain with the chance for thunderstorms. The beginning of the work week ahead looks typical with morning sun, afternoon thunderstorms, and high temperatures in the 70s.

June 4, 2008 Colorado has been rocked by strong thunderstorms over the past few days as the thunderstorms of late spring have brought big, beautiful thunderheads, plenty of hail, brilliant lightning and heavy rain. Today will be no exception as another round of rumblers will arrive this afternoon as a cold front moves across the state. There will again be a threat of some severe thunderstorms during the afternoon and evening.

A deep low pressure system will develop over western Kansas by early Thursday. Winds around this low will swing back into eastern Colorado and bring rain and thunderstorms to the plains. In the mountains, there will be enough cold air to change the rain to snow! Above 9,000 feet we may see a few inches of snow accumulate, with temperatures only in the 30s to low 40s - a raw, cold June day to be sure.

The storm system will spin out of the region by Friday, with warmer and drier weather back in the picture to start the weekend. Temperatures should bounce back into the 50s to low 60s in the mountains, 70s on the plains. By Saturday, typical June weather will return with highs in the 80s on the plains and 70s in the high country. The usual routine of morning sun and widely scattered afternoon storms will return as well.

June 2, 2008 9:02 p.m. Strong to severe thunderstorms popped up late this afternoon and evening around the Denver area, and east of the city. Once again today, as is typical for June, we had the necessary ingredients for severe weather. Large hail has been reported in Morgan, Adams and Weld Counties tonight. Up to 2-inch diameter hail was seen near Brighton in Adams County, and there were other reports of large hail across northeast Colorado. Today's thunderstorms fired-up late due to a "capping inversion" in the mid-levels of the atmosphere for most of the day. What this means, is that temperatures were too warm up above for the building cumulus clouds to break through. In the late afternoon hours, the mid-levels cooled just enough for the warmer air below to punch through and let the thunderstorms develop rapidly. As of late evening, most of the activity was moving off to the northeast along the Platte River Valley.

So, how do you cook up a "severe" thunderstorm? The necessary ingredients are moisture, lift, instability and wind shear. Most thunderstorms that pop up on a typical warm late-spring day are what we call "garden variety". This simply means, they're not "severe". You may see some lightning, gusty winds and small hail, but these storms quickly die off. "Severe" thunderstorms, or "Supercells" develop when all the ingredients are in place for long-lived strong updrafts and rotation. Severe thunderstorms are defined in the United States as having either tornadoes, wind gusts of least 58 mph, or hail at least 3/4 inch in diameter.

One basic tip for protecting yourself from severe weather is simply staying informed and alert. Watch the sky. When the clouds turn dark and the wind kicks up, you know something is on the way. When severe thunderstorms threaten, the best protection is to stay inside a sturdy building on the lowest floor. This protects you from lightning, debris and hail. Lightning is one of the biggest threats in Colorado due to our open spaces and high elevation. Simply put, when there's lightning around, don't be the tallest object! As for tornadoes, the best protection is a basement, or a room on the lowest floor of a brick building with no windows. Bathrooms offer good protection due to the pipes in the walls that help reinforce the room. Get into a bathtub and cover yourself with blankets if you don't have a basement. Trailers and mobile homes offer no protection from tornadoes. Most people are injured by the flying debris from a tornado. As we saw a few days ago in Windsor, strong tornadoes are possible in Colorado, so have a plan ready just in case!

This is the time of year to pay attention to the forecasts, and know whether there is a threat of sevee weather each day. Stay tuned to Denver's 7 and www.thedenverchannel.com. Our team of meteorologists and forecasters are dedicated to keeping you informed and safe from severe weather!

May 28, 2008 The satellite images from Wednesday morning are showing the thick clouds moving east and clearing conditions for the Denver area. Today will be breezy due to a surface low pressure system to our northwest. Winds will be in the 10 to 25 mph range through the day, with higher gusts at times. The trend is toward warmer, drier weather as we head closer to the weekend. A few isolated showers and thunderstorms are possible tomorrow, due to a little residual moisture on the plains, and evaporation from the heavy snowpack in the mountains. The plains and midwest are also getting a break today from severe weather, which is welcome news. The months of May and June are notorious for severe weather in Colorado, so we urge you to stay up to date with www.thedenverchannel.com and our TV broadcasts. The weather changes fast this time of year, so don't be caught off-guard. It's also a good idea to have a severe weather plan for home and work. Know a safe place to go in case of tornadoes, hail and lightning. Have survival gear in your home and car, like bottled water and canned food. A battery-operated NOAA weather warning radio is also a good idea. They're available at Radio Shack. As we saw last Thursday, tornadoes happen fast, with little warning sometimes. Don't be caught off-guard. Check in often with us here at the 24/7 Weather Center.

May 27, 2008 The cold front that slipped into northern Colorado on Monday brought us a cool, gray and damp Memorial Day. Today, that front will remain stalled over the area and will keep our weather a little cool and wet once again. High temperatures should manage to climb back into the low 60s, but that is still well below the normal highs for late May.

We should see a return to normalcy on Wednesday as the cool, moist airmass slides to the east of Colorado and warmer air flows back into the state. Temperatures will rebound into the 70s, with 80s on the way by Thursday. With the warmer temperatures, there will be more energy in the atmosphere that may help spark a few thunderstorms, but a major outbreak of severe weather is not expected.

The remainder of the week will feel just right for the ned of May and the beginning of June. Skies will be sunny in the morning, partly cloudy in the afternoon, with a few thunderstorms possible. High temperatures will hold in the upper 70s to mid 80s, with lows in the 50s. Now is the time of year that we need to keep an eye on the sky in the afternoon hours as thunderstorms can stir up plenty of trouble, as we have already seen.

May 23, 2008 May 2008 has been full of surprises, and yesterday was no different. Violent thunderstorms rumbled across the plains while snow fell in the mountains. A strong low pressure system in northern Colorado pulled warm, moist air up the Front Range on Thursday. The low pressure generated strong southeasterly surface winds, while winds aloft were from the southwest. When we get winds from different directions at different heights, we call it "wind shear", and it's a necessary ingredient for severe weather. That's exactly what we had on Thursday afternoon when a "wedge" type tornado struck near Windsor. In storm chaser lingo, a "wedge" is a large tornado with a wide base. We are awaiting the National Weather Service's survey of the damage. They will determine the "EF" rating of yesterday's tornado.

The supercell thunderstorm that produced the tornado developed just north of Denver in the late morning hours and spawned a tornado near Platteville about 11:30 a.m. that cut a 28 mile long path of destruction. One person was killed near Greeley. The violent weather is over for now in Colorado, however more strong to severe storms are possible in extreme northeast Colorado this afternoon.

Strong winds will still be swirling over Colorado again today, but the low pressure center has shifted a bit to the north and east, and we should be in the "dry slot" of the system, so the atmosphere will be a bit drier. For today, we're calling for just a slight chance of thunderstorms in the Denver area. In the mountains, more rain and snow showers are possible today. Winter just won't end in the high country!

The long holiday weekend should actually be pretty pleasant across the state. Scattered showers and thunderstorms will pop up again from Saturday through Monday.

Despite the cooler weather in the high country today, the overall trend is for the snows to keep melting quickly and that will keep streams running very high, fast and cold through the weekend. If you are heading to the high country, please be very careful near streams, and keep a close watch on small children. Meanwhile, on the plains, the concern will continue to be the high fire danger due to very dry conditions. Be extremely careful with the barbeque grill or other outdoors burning during this upcoming weekend!

May 21, 2008 Strong south winds will whip across Colorado today, bringing another very warm day to the plains, with high fire danger over the southeast quarter of the state. In the mountains, the main weather worry will be the warm temperatures that will quickly be melting snow. Streams are now running high in most mountain areas and there are flood warnings in effect for portions of the Green, Yampa, Elk and East Rivers.

A cold front will push into Colorado tonight and will bring cooler weather for the next few days. Scattered showers and thunderstorms will develop over much of the region both Thursday and Friday. The strongest storms will probably form east and north of Colorado, but we will at least get some moisture. In fact, a little snow will be possible above 10,000 feet in the mountains.

By the weekend, the winds will shift back to the west or southwest and that will sweep drier air back into Colorado from the desert southwest. Temperatures will be a little cooler than in recent days, but should still be pleasant with highs in the 70s on the plains and 50s to low 60s in the mountains.

May 20, 2008 Another warm day is on the way for Colorado with sunny skies giving way to scattered afternoon storms. Highs will hit the mid 80s to mid 90s on the plains, with 60s to low 70s in the high country. The temperatures in the mountains will be warm enough to keep that spring snowmelt coming down fast. Rivers and streams are now on the rise and some flooding has already hit the Elk River near Steamboat and threatens the Yampa, Green and East Rivers.

There will be a few widely scattered thunderstorms popping up late this afternoon, but the air is really too dry to support more than a brief shower, some locally strong winds and a little lightning. By late tomorrow, there will be an increase in moisture that will help inspire a few more storms. Temperatures will stay very warm, perhaps even five to seven degrees warmer than today. Fire danger will be high across the state on Wednesday, with the warm temperatures and gusty winds.

A cold front will arrive in Colorado on Thursday. Unlike last week's chilly fronts, this one will be a pretty lightweight deal and bring only a little cooling. Scattered thunderstorms will be a little more numerous, but it will not be a good soaker across the region. The weather pattern will stay a little cooler into the weekend, but there will not be much in the way of heavy precipitation.

May 19, 2008 Warm, dry and breezy will be the weather words for the next few days as a large high pressure system continues to hold over western Colorado - helping to steer storms away from the state. There might be a couple of gusty thunderstorms later this afternoon and again on Tuesday, but these storms will bring little if any rain, just gusty winds and lightning. There is very limited moisture over the region, so any storms that form will be high-based ( the bottom of the clouds will be high above the ground ). High based storms tend to have all the rain evaporate well before reaching the ground, so they only bring gusty winds and a light show.

The warm weather has hastened the snow-melt in the mountains and prompted the National Weather Service to issue some flood watches for some mountain streams. The Elk River near Steamboat, the Green and the Yampa in northwestern Colorado and the East River near Almont are swollen with icy water and expected to rise above flood stage during the next few days.

The next weather-maker for our state will come in the form of a cold front that will slip into Colorado late on Wednesday. This front will not be a strong storm system, but it should bring scattered showers and thunderstorms as well as a cooling trend for the second half of the week. Right now, the following weekend looks to be pleasant, with partly cloudy skies and temepratures in the 70s.

May 16-18, 2008 The weather pattern is shifting across the western United States and will bring back some warm, dry conditions for several days. The upper level winds have been blowing down from the northwest across the Rockies for the last week, swirling several fast moving cold fronts through Colorado. The result has been the rain and snow and the rather chilly temperatures.

Over the weekend, the jetstream will shift to the northeast of Colorado, allowing warmer and drier air to build into the region from the southwest. The weather will warm back into the 80s at lower elevations, with upper 60s to mid 70s in the mountains. The sunshine and warmth will be welcome for folks that have grown weary of the cool, wet weather. Although the chilly weather has not been very enjoyable for many, the benefit of the cool conditions has been two-fold, slowing the snowmelt in the mountains and keeping the fire danger down for a few days. The warmer weather will feel great, but the flood and fire concerns will return.

The warm and dry pattern will last through Monday, before a new storm system begins to form in the eastern Pacific and move into the southwestern states next Tuesday. Showers and thunderstorms will return to our weather picture starting late Tuesday of next week and continuing through Wednesday and Thursday. In the meantime, have a great weekend!

May 15, 2008 The weather pattern has been fast paced and a little flaky over Colorado for the past few days with periods of rain and snow. Another fast moving cold front has swept through the state, bringing several inches of snow to the mountains and foothills west and southwest of Denver. On the plains, cool, windy and wet weather can be expected today, with highs only in the low to mid 50s.

The wet weather will move out of the region overnight, with clearing skies and chilly temperatures. We will likely avoid any frost on the plains tonight, so gardens should be safe. Friday will dawn under a partly cloudy sky, with more sunshine expected throughout the day. The sun will help to boost temperatures back into the 60s at lower elevations, with 50s in the mountains.

Get ready for a great weekend! A large "ridge" in the upper atmosphere will rise up across the western United States and help to push the storm track back to the north of Colorado. Sunny skies and warmer temperatures will cover the area through the weekend, with highs rising into the 80s on the plains by Sunday. The recent rains, combined with sunny skies and warm weather, should really help green things up over Colorado. The warm and dry weather will last until late Tuesday, when a chance for thunderstorms will return to the region.

May 14, 2008 Tuesday's snowstorm for the foothills and mountains dropped as much as a foot of snow on some areas above 9,000 feet. The moisture from the storm was very welcome, but so is a little sunshine today. May is a month with frequent weather changes and the quiet respite between storms will not last long. Another fast moving cold front will zip into the state by tonight and bring more precipitation.

This next system should be a fairly modest one, so only light rain and snow showers are expected late this afternoon through Thursday morning. The increase in clouds will cut off much warming today, so we should see highs in the 50s to near 60, but not much more. Thursday will stay cool as well, thanks to clouds and scattered showers.

Once this next system gets out of here, we are in for a delightful stretch of days that will make for a perfect weekend. Sunny skies and warmer temperatures will team up to bring us a great stretch of days - the best we have seen in quite a while. Friday will see highs in the low 70s, Saturday and Sunday may get close to 80 degrees. The next cold front will not arrive until the middle of next week.

May 13, 2008 May is well named! It "may" be warm and beautiful or it "may" look like a winter scene! After a fabulous day Monday, a strong cold front roared across the state bringing much colder air, rain and snow. Heavy snow is likely today over most of the mountains above 9,000 feet, while a chilly rain/snow mix falls on the metro area. Temperatures in Denver will drop from the 70s yesterday to the mere mid 40s for highs today. In the high country, up to a foot of snow may pile up, while foothills locations could see several inches.

The plains will receive a very nice soaking rain, with many areas getting a good half an inch today. Despite the damp, cold nature of the day, this storm is most welcome as the moisture will quench thirsty soils and should help drop the fire danger for a while. Skies will clear tonight as the storm exits the region, but temperatures will be low enough that you might want to cover up your vegetable garden if you have already planted.

Wednesday will be a milder and drier day, but we will be in between storm systems as another cold front will move into the area on Thursday. This next system will be considerably weaker and will only bring light showers and slightly cooler temperatures for Thursday. The mountains will likely have rainshowers, mixed with some snow, but nothing too heavy.

After the Thursday storm moves out, we are in for a real treat. A nice upper level "ridge" will build in the jetstream and that means mild and dry weather across Colorado for the weekend! Temperatures will warm each day through Sunday and should top out near 80 by the end of the weekend. The rain and snow of earlier in the week will have soaked in and made everything green and beautiful!

May 12, 2008 Sunday was as perfect a day for Mom as anyone could ask for - sunshine, warm temperatures and gentle breezes. Today will be very pleasant once again, but there will be a big change coming in the weather tonight. A strong cold front will race across the state late today, ushering in some much colder air, along with rain and snow.

A WINTER STORM WATCH is in effect for most of the mountains and foothills tonight and tomorrow, with snow possible as low as 5,500 feet tomorrow. The cold front will be preceeded by showers and thunderstorms later this afternoon, and then much colder air tonight and early Tuesday. A strong north wind will develop tonight and that will increase the upslope along the Palmer Divide, so areas south of Denver in Douglas and Elbert Counties - places such as Castle Rock, Larkspur and Kiowa could pick up several inches of wet, slushy snow on Tuesday. In the mountains, snow will become heavy Monday night and may accumulate to 6-12 inches, especially in the northern and central mountains. Foothills locations west of Denver may see 3-6 inches of snow at elevations between 7,000 and 9,000 feet.

The storm will move out of the state Tuesday evening, with clearing skies and lighter winds. Wednesday morning could bring another freeze along the Front Range and northeast plains, with lows expected near 30 degrees. The weather will warm up again on Wednesday under sunny skies. Another weak storm will arrive Thursday, with mostly rain showers. Friday and next weekend will be warm and pleasant once again - good timing!

May 9-11, 2008 The unsettled weather pattern that has developed over Colorado will continue through the weekend, with a mix of sun-rain-sun expected. Friday will be a sunny day, Saturday brings cool, rainy weather and Mother's Day should be delightful!

A series of fast moving storms systems will continue to zip across the central Rockies. The next one will cruise through the state on Saturday, bringing showers and thunderstorms to lower elevations and some snow above 9,500 feet. By Sunday, that storm will turn into a nasty system for the Mississippi Valley, with heavy rain and severe thunderstorms expected to dampen Mother's Day from Chicago to St Louis to Dallas. In Colorado, our weather on Sunday will be picture perfect - sunny skies, light winds and warm temperatures.

Early next week will start pleasant, with sunny skies and warm weather expected Monday. By Tuesday, another storm system will approach with showers and thunderstorms. That system will also race out of here by Wednesday, but the longer range computer models indicate yet another storm will move in by next Thursday. Ah, such is Colorado weather in the month of May!

May 8, 2008 Denver awoke to thunder and hail early Wednesday and it looks as though Mother Nature may serve up another round of storms for today. Another in a series of upper air disturbances is swirling over the state and will bring more showers and thunderstorms to the area. The temperatures will stay a little on the cool side to produce much in the way of severe weather, but we may see some small hail and another half an inch of rain today.

Friday will bring a brief break in the action as the skies will clear and the rain chance fall away. Temperatures will warm back into the low 70s, making for a very nice day to get outdoors. The dry and quiet weather will not last long though, yet another storm system is on schedule to arrive by Saturday morning. More showers and thunderstorms are likely over much of Colorado for Saturday - making it a little soggy for soccer or other outdoor activities.

The timing of the storms could not be better for Mother's Day! We will again be in between storm systems and that will bring a winning weather combination for Mom! Sunday will be sunny and warm, with lovely blue skies. Perhaps a good day to take your mom on a picnic or help plant her garden!

May 7, 2008 A weak cold front moved though the state last night with scattered showers and a few thunderstorms. Rainfall early today has caused some headaches for commuters thanks to some locally heavy showers that created ponding, mud and local flooding on I-25. Meanwhile in the mountains and western sections of the state, the skies have been mostly sunny to start the day, although some showers will develop this afternoon. Today will be about 10 to 15 degrees cooler on the plains, and there will still be lingering showers around due to a departing upper air disturbance. To the west, another in a series of weak disturbances is zipping across the northern Rockies and will arrive in Colorado tomorrow, with another chance for showers.

The overall weather pattern will remain active over the next few days as these fast moving, but modest storm systems bring a chance for showers about every other day. We should squeeze in a nice day on Friday as Colorado will be in between these fleet weathermakers. Friday will be mostly sunny and warmer, with highs in the 50s to low 60s in the mountains and near 70 on the plains.

Saturday will turn cloudy and cooler again with yet another storm system. Right now, Mother's Day looks like a winner for moms across Colorado! Skies will return to sunny and temperatures should bounce back into the 70s. Sunday might make for a lovely day to take mom out for a picnic, or help plant some of her spring garden!

May 6, 2008 A weak upper air disturbance will drift over eastern Colorado this afternoon and help to stir up some thunderstorms. The skies will be mostly sunny through the morning hours, but clouds will develop by and lead to scattered showers and thunderstorms late this afternoon and evening. The outlook for severe weather is low, as the best energy in the atmosphere for really big thunderstorms will be to our east in Kansas and Oklahoma
