August 28-30 2008 All eyes are on the Gulf of Mexico this weekend as Gustav is expected to move over the very warm Gulf watersco and strengthen into a powerful hurricane before making landfall on Monday along the central Gulf Coast. With plenty of warm water and little wind shear, conditions will be right for Gustav to strengthen rapidly, possibly becoming a significant hurricane, perhaps a category three storm. There is a chance that the hurricane could track right into the New Orleans area - a path similar to that of Katrina.

If you would like to keep track of Gustav, or any other tropical system during the hurricane season, we have a very thorough Hurricane Info Page that contains forecast tracks, expected rainfall totals, and tons of other great information.

August 24, 2008 With the anticipation of the DNC rolling into Denver on Monday, the weather isn't looking to ruin the show.

There is a chance of thunderstorms and showers on Monday for the mountains and eastern plains as upper level moisture is lingering over the state. Denver however, should miss the thunderstorms and most of the shower activity on Monday. Tuesday will bring a little better chance of a shower to the Denver area and further east, with the slight possibility that couple of these showers and high based thunderstorms turning server.

Wednesday and Thursday we look to be cooling down just a bit with temperatures into the lower to mid 80s, but with lots of sunshine for all the festivities of the DNC. The big night on Thursday looks to be beautiful, with clear skies and mild temperatures in the low 70s Thursday evening for the speech of Barack Obama outside at Invesco Field.

If you plan on staying in Denver this weekend once the DNC is over the party will continue with great weather. Friday through Sunday temperatures will be nice in the mid to upper 80s with plenty of sunshine. During the weekend the evenings also look to be very nice with mild temperatures and lows overnight in the middle 50s.

The weather this week doesn't appear as it will rain on the DNC's parade. Giving everyone a great opportunity to get out and see all of the beautiful sights of Denver and this great state.

Don’t forget for all of the visitors to Denver we have other great tools on our weather page at the DenverChannel.com such as: Airport Status, Discovering Colorado and My 24/7 Weather. Where you can get forecast to the locations you may be traveling to.

August 18, 2008 Tropical Storm Fay is expected to strengthen into a low-grade Hurricane before making landfall over the southern portions of Florida, but it will be the rains over the wind that'll be the biggest story of this.

The tropical system is expected to stall out over Florida and bring a multi-day stretch of heavy rains that could lead to totals of 10-20" of rain before all is said and done. This could lead to catastrophic flood problems for what has been a drought-striken area. If you want more information on Fay and any other tropical weather information, check out our Hurricane Page.

August 17, 2008 The slow moving soggy storm that dumped 2 to 4 inches of rain on the eastern half of the state over the weekend has finally moved away. Drier and warmer weather can be expected for the next several days, bouncing highs back into the 80s to low 90s by Thursday. The upper air disturbance that spun through the region, brought the rain and even some snow to the mountains above 11,000 feet over the weekend.

Rainfall totals from the storm system were pretty amazing, especially in light of the very dry conditions that have plagued most of the eatsern plains this year. Most of the Front Range areas along and east of I-25 managed to pick up 2 to 3 inches of rain, with a few spots even getting four inches of liquid! The rains came hard, but not so intense that the moisture could not sink into the soil to a great extent. Although the weather was not terribly pleasant for outdoor activities over the weekend, the long drink of water was something that lawns, fields and gardens had not seen in a very long time.

The weather will be warmer and drier for the next several days. Little rain is expected through Thursday and the high temperatures will climb back into the upper 80s to low 90s by Wednesday and Thursday. The next storm system will come in the form of a cold front that will slide into the state on Friday. Showers and thunderstorms will be possible again by the end of the week - perhaps not the best of timing as the weekend draws near.

August 16, 2008 The weather pattern across Colorado is stuck in neutral as a big, wet weather system has stalled over the state. Cold, wet and even white weather has settled over the central Rockies. Most areas over the eastern half of the state have received one to two inches of rain in the past 36 hours, with another half to three quarters of an inch on the way. The upper air disturbance that dropped into the area on Thursday will slowly weaken and move out by the end of the weekend. No hope for nice, warm and dry weather for the rest of the weekend, though as cool and wet weather will hang on through most of Sunday.

In the mountains, the snow level dropped to near 10,000 feet, with several inches of snow falling on the Continental Divide. A mix of rain and snow will continue over the mountains through early Sunday. The only areas missing out on the moisture have been over the southwestern mountains, where skies have been partly cloudy.

By early next week, the upper air disturbance will move out of the region and milder and drier weather will return to the state. Highs will bounce back into the 80s at lower elevations, with 70s in the mountains. Hard to believe that just two weeks ago, Denver had highs in the low 100s!

August 11, 2008 Forecast models continue to indicate a welcome change in the weather for the weekend! If you're tired of the heat from this summer, you'll love the 60s in store for Friday! A gradual warm-up will quickly unsue, but even then, highs will only be in the 70s through the weekend before 80s return in time for the next work week. Lows will dip into the 50s and maybe as low as the upper 40s in some places.

With the cooler temperatures will come a better chance for widespread rain! After the front passes, low level moisture will increase across the region bringing with it a higher chance for rain. With instability lower due to the cooler temperatures, a more general rain is expected rather than quick shots of torrential rains from strong thunderstorms. A few rumbles of thunder will be possible each afternoon, but the overall severe threat will be low.

Mountain peaks over 10,000 feet may see a few inches of heavy wet snow. Snow levels will not fall much below 10,000 feet, so those in the foothills likely won't see any flakes.

Enjoy the cool break while it lasts as the summertime pattern will return by next week!

August 11, 2008 Colorado has been enduring a long, hot summer, with Denver recently setting a new record for consecutive days of 90 degrees or higher with 24 straight scorchers! We are about to get a very pleasant break from the heat, courtesy of an approaching cold front that will bring a taste of fall to the region. The front will arrive Wednesday night and will sweep through the state by Thursday morning. This front will bring some cool air from Canada that will hang around for several days. The temperatures aloft will be cool enough to bring rather unstable conditions to the region, bringing us a good chance for showers and thunderstorms Thursday through Sunday.

The cool conditions will bring us some of the lowest temperatures we have seen since early June. Highs by the end of the week will only climb to the low 70s, with nighttime lows in the 40s to low 50s. There is a chance that some snow may fall over the higher elevations of the northern mountains Friday night and Saturday morning - keep that in mind if you are camping.

The weather will begin to warm up again by Sunday, with highs expected to rebound into the 80s for early next week. We have been through such a long hot streak, this break in the summer swelter will feel pretty nice. By next week, folks will be refreshed and ready for some more good old summertime weather.

August 11, 2008 The recent rounds of heavy thunderstorms have dumped some copious amounts of rain on a few spots across the Front Range and Eastern Plains. On Sunday, another batch of soggy storms caused some flooding in Weld County east of Greeley. The storm activity should shift a little to the east today, allowing for more sunshine and warmer temperatures. There will be some scattered storms developing this afternoon, and the few that do form will again drop some locally heavy rainfall.

The next few days will be warm, but not extreme, and there will be some scattered thunderstorms. If you want to check the local precipitation tallies, a good place to check is the CoCo RaHS network of weather watchers. For all the details, go to www.CoCoRaHS.org.

August 6, 2008 It's official, the new record that will go down in the books for consecutive days above 90 degrees is 24 days. The high today has only warmed to 85 degrees so far and doesn't look like it will warm much more. We have strong storms moving into the Denver Metro area. A flash flood watch has been issued for portions of Western and Central Colorado including the Denver Metro area. There is also flash flood warnings for several counties in Southwestern Colorado. The reason for all of these watches and warnings spawn from the slow moving storm cells. These storms are moving extemely slow dropping between 2-3 inches of rain in a matter of only a couple of hours. Localized flooding is the story of the day, which has been a nice break from the dry hot conditions Denver has been experiencing over the past couple of weeks.

We get our official rainfall totals from a website called CoCoRaHS. CoCoRaHS stands for Communtiy Collaborative Rain, Hail, & Snow Network. If you want to become one of the thousands of weather watchers that log data into the website, it's extremely easy and fun! Once registered at http://www.cocorahs.org, you will receive an official rain gauge in the mail. Everyday, log onto the website and log how much rain has fallen into the rain gauge at your house. We then take this information and use it for climatological data and sometimes include it in our newscasts!

Remember with heavy rain, never drive over flooded roads since it is unknown how deep the water is. Severe storms are likely to continue popping up this afternoon clearing out by late evening. This is all thanks to that cold front that moved into the state yesterday and has since become stationary. The wet weather has helped only a small amount since Colorado is still well below average for summer precipitation.

August 5, 2008 Today marked our 24th day in a row where temperatures remained at or above 90 degrees. Today at 2:43 PM DIA recorded a high temerature of 91 degrees. So far 2008 Denver has seen 41 ninety degree days and the record to beat is 61 days which was set in 2000. Today Denver will see the streak come to an end with highs cooling into the 80s. The 80s will continue for the next few days before we head into the weekend where temperatures soar back into the 90s.

This cooler and much more bearable weather is due to a cold front that finally managed to make its way across the Colorado state late Monday night into Tuesday morning. For the past few weeks the cold fronts coming off the pacific coast have just passed us to the north leaving the north cool and wet, while we have been trapped under a huge ridge of high pressure keeping us hot with renlentless ninety degree weather. That ridge of high pressure has kept us dry and hot with little instablility within the atmosphere, giving us little hope for storms and showers throughout the metro area. With this cold front, our area will see more moisture and more instablility leaving us with a much better chance for storms and showers through the end of the week.

This cold front will stall up against the mountains through the middle of the week, cooling off eastern Colorado, but leaving the western valleys still hot and dry. This front will be the boundary where showers and thunderstorms will develop and move east. Some of these storms that develop could bring locally heavy rain, increasing the risk of localized flash flooding. These storms over the next few days could also bring gusty damaging winds, frequent lightning increasing our fire danger, and large hail. However, we need the rain because Denver is well below rain fall for 2008. The total 2008 precipitation is only 3.28 inches which is 2.06 inches below the driest year in Denver's history, which was 2002 at 5.34 inches. For more information on precipitation amounts around the state visit cocorahs.org. Denver is techniquely not considered to be in a drought but we all still need to do our part to conserve water in our ever growing city.

August 3, 2008 Another day, another record with temperatures in the high 90s. Sunday marked our 22nd day in a row that temperatures were at or above 90 degrees. So far 2008 has 39 ninety degree days and the record is 61 days set in 2000. The month of August has on average 9 days of 90 degree heat while September has 2, so the heat could manage to reach that record level if we continue to have this weather pattern stick to us for a while. The strong of super heated weather will come to at least a temporary end this week as a cold front will move through the state by Tuesday morning. Highs will be around 85 with a better chance for afternoon showers and thunderstorms.

This cold front will stall up against the mountains through the middle of the week, which will cool off eastern Colorado, but leave the western valleys pretty hot. This front will be the boundary which showers and thunderstorms will develop on and move east.

The total 2008 precipitation is only 3.28 inches which is 2.06 inches below the driest year in Denver's history, which was 2002 at 5.34 inches. Some areas around the state might have locally heavior amounts. For more information on precipitation amounts around the state visit cocorahs.org.
