April 29, 2006 - Colorado's Changing ClimateColorado's Changing Climate, a weather special by the 24/7 Weather Center, aired Friday night on 7NEWS. I hope you got to watch it! There was a lot of great information.In the sidebar on this page are video clips from the special.
Take some time and check them out this weekend.After a gloomy start the weekend will end on a nice note with sunny skies and mild temperatures arriving by Sunday.April 28, 2006 - Chilly Start To WeekendI know you probably have weekend plans and aren't excited about this cool and damp weather. However, it is really great news for delaying the premature start to what could be a record setting wildfire season.Both today and tomorrow will be a bit gloomy but we should be able to salvage Sunday with sunny skies and temperatures rebounding back to near 70 degrees.Did you know that today is Arbor Day? Click Jess' Garden in the blue navigation menu on the left to learn more.April 27, 2006 - Cold Front ApproachingA cold front approaching from the northwest and an area of low pressure to the south will affect the weather over the Rockies to end the work week.The cold front will bring cooler and potentially damp weather to northern Colorado. The low pressure may help spawn some strong thunderstorms over extreme southeast Colorado as it passes by on Thursday afternoon.Get the latest forecast for where you live by checking out My 24/7 Weather in the blue navigation menu on the left of this page.April 26, 2006 - 2006 Wildfire SeasonWe've already seen a very active year in terms of wildfires, and technically, we aren't even in the actual wildfire season, which heats up late spring and through the summer.Now is the time to take precautions, especially if you live in the foothills or mountains. In fact, some homeowners are finding themselves in jeopardy of losing their insurance right before the wildfire season begins. Watch the video above to learn why.Get outside today and enjoy the clearing skies after some early morning fog. We should climb some 15 to 25 degrees higher than where we were yesterday for afternoon highs.April 25, 2006 - The Warming Trend BeginsTemperatures dropped some 40 to 50 degrees between Sunday afternoon and Monday afternoon, with light snow reported in many Front Range cities and towns.We will begin a slow warming trend today, with temperatures climbing toward 50 degrees. We will aim for 60 degrees Wednesday and the 70s come the weekend.Did Monday's storm system help end the extremely dry conditions and high fire danger? Watch the video linked above to find out.April 24, 2006 - Hail To Snow, It Must Be AprilIt's a weather roller coaster ride today around eastern Colorado, as temperatures take a dive from the upper 70s and lower 80s to the upper 30s and lower 40s.Sunday evening we saw the first severe thunderstorm warnings of the season issued in northeast Colorado. The cold front helped trigger a few thunderstorms that dropped large hail.Hail reports of up to 1 inch in diameter were received from Golden to DIA, and Ken Caryl to Aurora.One of the criteria for a severe thunderstorm is hail measured at 3/4" or greater in diameter.As the evening progressed, the storms met some warmer and more moist air toward Kansas, and organized into a line of severe storms across Yuma, Cheyenne, and Kit Carson counties.April 23, 2006 - Last Of The Red HotsSay goodbye to the red hots of April with a major cool down arriving later today and into the overnight hours. We could be talking some snow by Monday evening across much of Colorado.Some much needed precipitation is on the way with an approaching storm system over the next 48 hours. This won't be an April soaker but we'll take what we can get!If you have some things to get done outdoors today, head out early. By late afternoon the clouds and wind will be on the increase as the front moves into Colorado.April 22, 2006 - Happy Earth DayToday is Earth Day, a time to think about what you can do to help the environment. There are several cleanups, recycling events, and tree sales all around the state today. Click on Colorado's Water in the blue nav bar on this page and then look for the Earth Day information in the calendar of events.April 21, 2006 - Severe Weather Awareness Week: Lightning SafetyThunderstorms produce some of the most powerful weather on Earth, including hail, tornadoes and strong winds. One of the most dangerous aspects to a thunderstorm, however, is lightning.Over the last decade in Colorado, lightning has been the #1 killer over all thunderstorm hazards, including flash floods. We average 3 fatalities and 18 injuries each year.Lightning is also a major cause of forest and rangeland fires in Colorado. These "dry lightning" flashes comes from thunderstorms with little or no rainfall.TRIVIA: How many cloud to ground (CG) flashes hit the ground each year in Colorado? Nationwide? The answers will amaze you! Read to the end of this blog entry to find out the answer. Each bolt of lightning contains millions of volts of electricity...enough in fact to supply power to several homes for a month or more! As lightning travels through the air, it heats the surrounding air molecules up to 50 thousand degrees Fahrenheit, creating a shock wave that we hear as thunder. It can be up to 1" in diameter. It's thought lightning occurs most frequently during the afternoon and evening hours.Lightning is unpredictable...sometimes striking an object and leaving another one nearby untouched. Often lightning will hit a tall object like a tree, and then travel down the object, hitting anything in its path. We saw a good example of this recently west of Fort Collins. Lightning struck a tree and traveled down the trunk, through the root system, and into a house...damaging glass inside and injuring a little girl. As the lightning traveled through the root system of the tree it blew up the earth, leaving a trench in the yard.Most lightning deaths occur outdoors, usually under tall objects such as trees, on hilltops, or in the water.Did you know lightning can travel up to 20 miles away from a thunderstorm?In a state like Colorado, where so many residents and visitors are enjoying the beautiful outdoors during thunderstorm season...its good to know the following method of estimating your distance from lightning. We refer to this as the "FLASH TO BANG" technique. To employ...
- Count the number of seconds from the time you see the lightning, to the time you hear the thunder strike
- Stay off corded telephones (lightning can travel through phone lines trying to ground itself) Unplug sensitive electronics, such as computers Stay away from electrical devices Get out of the bath or shower, lightning can travel through plumbing Get off rivers and lakes and out of pools Always stay away from metal objects as they become excellent conductors of electricity
- Seek shelter in a building or an enclosed vehicle with a metal roof (make sure all windows are closed) Never seek shelter under a tree or small group of trees In a heavily forested area, seek shelter in a low spot and away from the taller trees, but avoid areas that might be prone to the #2 Colorado severe weather hazard...flash flooding If caught out in the open, DO NOT lie flat on the ground...INSTEAD...squat low to the ground and clasp your hands around your knees, with your chin to your chest (this makes you the smallest target possible and minimizes your contact with the ground
- The safest place to be is in a well-built structure, in the basement, storm cellar or saferoom. If none of these are available where you are, move to the interior of the structure, either in a hallway or small room such as a closet, on the lowest floor. Cover yourself with blankets or get under heavy furniture to protect yourself from flying debris. LEAVE MOBILE HOMES FOR MORE STURDY SHELTER. In places with large, poorly supported roof spans, such as in shopping centers or gymnasiums...seek the designated tornado shelter, often the bathrooms. If there is no time to locate these places, dive under a table or desk to protect yourself as best you can from flying debris. If driving, never seek shelter under an overpass/viaduct. These can be a collection point for debris, and actually cause higher windspeeds. Simply drive away from the tornado at a 90 degree (right) angle. If the tornado is coming too fast for you to safely get away, abandon the vehicle and lie face down in a dry ditch or culvert, as far away from the vehicle as possible. COVER YOUR HEAD.
- Flash Flood or Flood Watch -- simply go about your plans, but WATCH...and know your plan of action should flooding conditions occur. Flash Flood or Flood Warning -- Either flooding conditions have already been reported, or are imminent. You need to immediately stop what you are doing, assess the situation, and be prepared to evacuate if necessary. If you ever catch yourself in a flooding situation immediately seek higher ground or climb to safety before access is cut off by floodwaters.
- Don't camp or park your vehicle along creeks and washes, especially when threatening conditions are present. If you are near a river or body of water, be aware of the water levels and have a plan for seeking higher ground in place should you need it. Never enter an area that is already flooded. Too many times we've seen people drive into areas that are already flooded. You have no way of knowing if the road is still there, and just how deep the water is. As little as 6" of moving water can carry a car. Remember...vehicles will float engine down...and within seconds you can find yourself in extreme danger. Nearly half of all flood fatalities are vehicle related. Be aware that erosion from swift moving water can cause the banks to become unstable. If you are walking along a stream, creek, or river...you could trigger a landslide if the earth has become unstable. Never walk through flowing water on foot if the water level is at or above your knees. Keep children away from high water, storm drains, viaducts, and arroyos. Be especially careful at night, when it may be difficult to see flood dangers.
- July 9, 1953 (Heavy rain in Montclair and Mayfair areas east of Denver caused over $1 million dollars in damage. 3.9" of rain fell at Lowry AFB, while only a trace fell in north Denver, Lakewood, Golden, and Englewood.) May 9-15, 1957 (Denver and Frederick, 3 killed) June 14-20, 1965 (Flooding in the South Platte and Arkansas River Basins, 21 killed) July 31-August 1, 1976 (Big Thompson Canyon, at least 139 killed) July 9, 1996 (Pueblo, 2 killed) July 12, 1996 (Buffalo Creek) July 28, 1997 (Fort Collins, 5 killed)
- SEVERE THUNDERSTORM WARNING -- ISSUED FOR WIND GUSTS OF 58 MPH OR GREATER...OR HAIL OF AT LEAST THREE QUARTERS OF AN INCH IN DIAMETER. TORNADO WARNING -- ISSUED WHEN TORNADOES ARE IMMINENT OR OCCURRING. FLASH FLOOD WARNING -- ISSUED FOR RAPIDLY DEVELOPING LIFE THREATENING FLOODING.
