KEY MESSAGES

- Very hot again Sunday with isolated, high-based t-storms possible.

- Slightly less hot Mon and Tue with increasing chances for afternoon t-storms, especially higher terrain.

- Still appears rain chances increase over the entire region from mid-week into next weekend, with heavy rain and flash flooding possible.

SHORT TERM /THROUGH SUNDAY/

Issued at 119 PM MDT Sat Aug 8 2026

Isolated high based showers/t-storms have developed across the area this afternoon in response to weak upper wave and thin layer of mid level moisture drifting southeast across CO. Most activity has been weak and short-lived so far, with pockets of locally gusty winds the main storm feature as dry sub-cloud layer and 60+ degf t/td spreads are unfavorable for much if any precip reaching the ground. Best chance for a more long lived storm and perhaps a more organized strong wind threat the rest of the day will be over Kiowa County, where instability is slightly greater and weak surface boundary is present to aide in storm formation. Any lingering activity early this evening will end quickly by sunset, with winds settling and skies clearing overnight.

On Sunday, near repeat of today, with very hot temperatures and the threat of isolated afternoon thunderstorms once again. May see slightly better coverage of storms given modest uptick in mid-level moisture, though still expect most activity to produce more wind than rain for another day as surface layer remains dry. Mountains will see just enough cloud cover to trim a degf or two of max temps, while plains see little relief from the heat with readings well over 100f once again. Left current heat advisory in place, as lower Arkansas River Valley will again see maxes around 105f.

LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/

Issued at 119 PM MDT Sat Aug 8 2026

Upper high slowly drifts east across NM Mon/Tue, with a continued slow uptick in moisture across srn CO both days. As a result, thunderstorm coverage, especially over the mountains, should increase, with deep enough moisture for at least pockets of measurable rainfall across the higher terrain. Weaker convection possible on the plains both days, with still some dry low level air and large t/td spreads to overcome away from the mountains, so more of a wind than rain threat here. With increased moisture/clouds, max temps will drift downward a few degf both days, though readings will still be near/slightly over 100f on the plains each afternoon. Held off on a heat advisory for Mon as current forecast temps are slightly below heat thresholds, though Springs/Pueblo/Canon City will be close.

Center of the upper high then makes a more substantial eastward shift into the srn plains from Wed into the weekend, opening the door for moisture to rotate northward from nrn Mexico through the Desert SW into CO. Late week cold front on the plains will also provide a surge of low level moisture to areas along and east of the mountains as well, especially in the Thu/Fri timeframe. Expect widespread showers/thunderstorms from Wed into the weekend as a result, with at least some activity lingering well into the night under the moist plume. Locally heavy rainfall and flash flooding definitely a concern, especially eastern mountains/I-25 corridor Thu/Fri behind the cold front. Temps will continue to cool back toward seasonal averages or slightly below by the end of the week as clouds and precip knock back the heat through next weekend.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 509 PM MDT Sat Aug 8 2026

Localized erratic wind bursts from high based virga/cumulus build ups will be possible at all three terminals through 01z. While -SHRA is not likely to reach the ground, the variable nature to wind directions and sudden localized bursts of wind up to 45 kts necessitate the addition to tempo groups for -SHRA this evening. Otherwise, winds will settle into light diurnal patterns after sundown. Sunday will be very similar to today, starting out hot and dry with light diurnally driven winds before becoming dominated by outflows from high based virga/cumulus build ups after 20-21z. Any Cigs will remain VFR. -KT
