KEY MESSAGES

- Critical fire weather conditions are expected for portions of our southeast plains this afternoon. More widespread chances for high fire danger may be possible on Wednesday.

- Chances for showers and thunderstorms increase off and on throughout the week, especially from Thursday onwards into this weekend.

SHORT TERM /THROUGH TONIGHT/

Issued at 104 AM MDT Mon Apr 6 2026

Ridging weakens and flattens overhead today, increasing zonal flow over the region. Lee troughing develops this afternoon, keeping gusty winds mainly across our southeastern plains. A Red Flag Warning remains in place for Baca County, and portions of Las Animas and Prowers may see briefly elevated fire weather conditions this afternoon as well. Temperatures are likely to warm up into 60s for mountain valleys, with 70s and few low 80s on the plains. Humidity values fall into the single digits and low teens, but winds look to remain below critical thresholds for most areas. Gustiest winds remain over the southeast plains. Increasing mid- level and upper- level moisture will lead to increasing cloud cover throughout the day, but most areas look to remain precip- free. Slight chances for isolated showers over the San Juans and southern Sangres develop later this afternoon, with a few sprinkles possible over the higher elevations of the Pikes Peak region and the Wets as well. A weak cold front backs across our plains later this evening, though it's impacts may not be felt until tomorrow. Overnight lows in the 20s are likely for mountain valleys, with 30s and low 40s on the plains.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 104 AM MDT Mon Apr 6 2026

Tuesday and Wednesday..

Tomorrow's highs look to be a few degrees cooler than today thanks the aforementioned cold front. We will still be near normal for this time of year. This means highs in the 60s for mountain valleys and the I-25 corridor, with low 70s across our far eastern plains. Models continue to bring a weak open wave across the southern Colorado border on Tuesday, which looks to help spread precip chances across the area, especially over and near the mountains. Light snow accumulations above 10,000ft will be possible. Embedded thunderstorms will be possible across the area as well. We dry out and warm up quickly on Wednesday as a stronger system traverses the northern Rockies and pushes into the northern plains. This will lead to downsloping and warming on the plains, with highs soaring back into the upper 70s and 80s. Critical fire weather conditions will be possible for the San Luis Valley, Fremont County, and the I-25 corridor. Models send a cold front across our plains Wednesday night.

Thursday Onwards..

Models continue to hint at another quick embedded wave and more precip chances around Thursday. If the Wednesday night cold front ends up coming in later, we may also have critical fire weather concerns for Thursday, but at this time we look to be cooler with easterly post-frontal winds and increasing dewpoints on Thursday. Showers and thunderstorms will be possible on Thursday, and will remain possible for Friday and Saturday as well. Ensemble guidance still brings a low onshore over southern California in the late-week timeframe, though the details of how this incoming system might progress remain foggy at best. With increasing moisture ahead of and during the system's passage, it seems an overall increase in coverage and intensity of showers and thunderstorms will be likely for Thursday into this weekend.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 533 AM MDT Mon Apr 6 2026

Variable VFR cloudiness will overspread the TAF sites over the next 24 hours. Winds will be generally diurnally driven today with high based showers developing over the mountains during the afternoon. These may bring -SHRA at KALS along with erratic gusty winds with a wind shift from the northwest during the late afternoon/early evening. Winds will shift out of the east then northeast this evening at both KCOS and KPUB with gusts up to 20 kts at times with a frontal passage. Winds will decrease again towards dawn under continued VFR mid/high level cloud cover. -KT
