LIVE BLOG: TRACKING SEVERE STORMS ACROSS SOUTHERN COLORADO 1:30 PM | TORNADO WATCH IN EFFECTA TORNADO WATCH is in effect for Baca, Prowers, Bent, and Kiowa counties until 8:00 PM this evening. https://twitter.com/DornWx/status/1930703079483023711?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Etweet This will provide additional fuel for thunderstorms to develop this afternoon. Storms will begin to pulse up in the mountains around the lunch hour before reaching I-25 between 1-2 pm.
Landspout tornadoes are particularly common in eastern Colorado

3 days ago | koaa.com | Casey Dorn

June is Colorado's most active month for tornadoes. Our state sees a high number of a special type of tornado called a landspout. As usual, a lot of that has to do with the mountains. A supercell is a thunderstorm that spins. The storm's updraft - essentially the entire storm rotates. These powerful storms can then stretch that rotation to the ground. This produces a supercell tornado.
May was an unusual weather month in Colorado - even by Colorado standards

4 days ago | koaa.com | Casey Dorn

May of 2025 in Colorado was unusually active, wet, cool, and stormy. And that pattern is set to continue this June. The month started wild out of the gate. Pikes Peak was clobbered by over four feet of snow early in the first week of the month. That snow melted fast, leading to high turbidity, or cloudy water, in Manitou Springs and prompting a water crisis. Severe weather was another big story.
First week of June brings stormy pattern to southern Colorado

6 days ago | koaa.com | Casey Dorn

Tonight's Forecast:June has started off how March ended. Wet. Storms this afternoon will continue moving southeast tonight, in a pattern that has been rinse-and-repeat. A couple of weaker showers and periodic clouds remain possible later tonight although the main thunderstorm action should be done for the day as there is no longer energy available to sustain storms once the line moves past.
June begins with temperatures in the 80s in southern Colorado, more PM storms

1 week ago | koaa.com | Casey Dorn

Tonight's Forecast:Storms will continue to move off the mountains over the next few hours - and a couple will be on the strong side, with gusty wind and small to isolated medium sized hail (to 1" in diameter briefly). Today's set up favors isolated pulse severe thunderstorms. A high amount of thunderstorm energy exists, but winds in the sky aren't particularly supportive of storm organization.
Warm this weekend in southern Colorado with isolated afternoon storms

1 week ago | koaa.com | Casey Dorn

Tonight's Forecast:Thunderstorms will continue to move southeast tonight off the mountains, through the I-25 corridor, and then into the eastern plains, slowly losing intensity after sunset. Storms this afternoon formed from a weak southwestward moving boundary that provided additional lift and focus for storms over the Front Range, which then tapped into plentiful moisture and lift to produce the storms across the area despite fairly weak winds.
Warmer temperatures, isolated dinnertime storms, and more sunshine Tuesday

1 week ago | koaa.com | Casey Dorn

Tonight's Forecast:Small hail was widely reported with the line of storms that moved off the Front Range mountains this afternoon into I-25. Most hail was the size of a pea, with a few reports of marble sized hail (0.5"). Unlike the last couple of days, that's our main and only round of storms today. As the line continues east, skies will eventually clear either fully or partly. We could see another quick sprinkle or two, but the bulk of the rain is done.
Cool with more storms on Memorial Day, but a bit more sunshine too

1 week ago | koaa.com | Casey Dorn

Tonight's Forecast:After yesterday's isolated severe, and more widespread general thunderstorms, today has been unseasonably chilly. Low cloud cover and persistent upslope flow throughout the day have held temperatures steady and tamped down thunderstorm energy. Tonight, we keep the same pattern. However, a weak upper level disturbance - part of a larger area of low pressure - will roll in from the west during dinner time.
Thunderstorms will be widespread Sunday and Monday in southern Colorado

2 weeks ago | koaa.com | Casey Dorn

Tonight's Forecast:A Severe Thunderstorm Watch is in effect for El Paso County and Teller County through 8:00 PM tonight. Storms today will be isolated, but those that form will be strong. Therefore, you may not see a storm, but you should be prepared to take shelter if a warning is issued for your area. It's also a good idea to have a place to move your car to your garage, or another covered location, if needed. I do see the potential for a storm or two to persist past 8 PM.
