KEY MESSAGES

- One more day of scattered to numerous showers and thunderstorms across the area today, with a flash flood risk for the Aspen Acres burn scar, and one or two severe storms possible along I-25.

- Drier and warmer on Friday, with mainly isolated mountain showers and storms.

- Thunderstorm chances will increase this weekend and into next week, especially over the mountains, as deeper moisture returns to the mainly the western half of Colorado.

SHORT TERM /THROUGH FRIDAY/

Issued at 1236 AM MDT Thu Aug 27 2026

Usual lingering convection over the far eastern plains early this morning, and again expect most activity to end or shift into KS well before sunrise. Expect one last round of fairly widespread mountain convection this afternoon as moisture/instability remain in place, with storms pushing into the I-25 corridor during the late afternoon and evening. Eastern mountains look most susceptible to stronger storms and heavy rain, with a low threat of a severe storm or two along I-25 where modest 0-6km shear(20-30 kts) and CAPE(1000-1200 J/KG) coincide. Models show only a few weakening storms drifting east of I-25 in the evening, as best forcing for storms on the plains will be well north in nern CO/wrn NE. Flash Flood Watch looks good for the Aspen Acres again today, though just like yesterday, ultimate location and magnitude of any flooding will depend on difficult to forecast mesoscale/convective details.

Upper ridge flattens slightly Fri afternoon, with mid level wly flow bringing in at least a temporarily drier air mass to the region. Low/mid flow on the plains turns more wly as well, with deepening lee trough east of I-25. Expect a substantial downturn in convective strength and coverage Friday as a result, though isolated mountain storms will remain possible from mid- afternoon into early evening. Max temps will respond to general wly downslope flow, with maxes back into the 90s on the plains, with 80s most interior valleys and mountains.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/

Issued at 1236 AM MDT Thu Aug 27 2026

SW flow aloft strengthens across CO on Sat, as center of the upper level high drifts back eastward into TX. Renewed tap of mid-level moisture will work into the state by late Sat afternoon, and with weak s/w trough moving across, expect fairly widespread showers and storms to return to the mountains, especially along the Continental Divide. Swly steering flow will take a few storms into the I-25 corridor Sat evening, while the plains stay mainly dry, as breezy sw surface winds behind the lee trough in wrn KS aren't particularly helpful in keeping activity going away from the higher terrain. Deep mixing Sat will squeeze a couple more degf out of the air mass, with maxes into the 90s on the plains (a few 100f readings in the lower Arkansas Valley), and 80s mountains and valleys. Strong upper wave then races eastward through the nrn Rockies Sun/Mon, with surface cold front dropping through the area late Sun/early Mon. Mid level moisture will continue to flow across the state both Sun/Mon, with widespread showers and thunderstorms over the mountains both days, lesser chances on the plains. Still hot on Sun ahead of the front, then slightly cooler Mon/Tue behind it. Precip chances may then decrease slightly Tue/Wed as main moisture tap shifts back west of Colorado, though moisture never goes away completely, so isolated afternoon/evening showers and thunderstorms will persist, especially over the mountains back toward the Continental Divide.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 1046 PM MDT Wed Aug 26 2026

low chance of some passing light showers during the first few hours of this fcst period otherwise VFR. Another round of passing -tsra with gusty winds will be possible late tomorrow afternoon and early evening. Outside of any convective activity, winds will be mainly light and diurnally driven.
