- Widespread high fire danger Thursday through Saturday.

SHORT TERM /THROUGH WEDNESDAY/

Issued at 1129 AM MDT Tue Mar 10 2026

Rest of Today and Tonight...

Dry and windy through the rest of the day today. Expect portions of Fremont county to retain critical fire weather conditions, with breezy gap flow and low RH values. Meanwhile, looking aloft, southeast CO sits just south of an approaching jet while a cutoff low moves to our south. As the low pressure moves, some localized areas of lift will give us the chance for some isolated showers, and potentially a weak thunderstorm or two, over the southeast plains later this afternoon into the evening. That being said, the track of the low has been consistently nudging south, away from our CWA, so even if storms do manage to fire, little to no QPF is anticipated. If a thunderstorm manages to form, it will be short-lived, likely only producing winds to 40-50 mph as it gusts out. The passing upper disturbance will send a cold front south across the plains this evening into tonight, bringing in some cooler air. Overnight lows will be in the 20s-30s over the plains, and generally in the mid-low 20s for the high valleys.

Wednesday...

Generally cooler, with temperatures closer to seasonal averages within the post-frontal airmass. Brisk north winds will stick around over the plains, with high temps only climbing into the 40s-50s over most areas. Meanwhile, dry and generally warm conditions will remain in the San Luis Valley, with a few hours of spotty critical fire weather conditions possible during the afternoon. Though RH values will probably dip below 15 percent for a few hours, winds at this time appear too marginal to warrant any fire weather highlights.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 1129 AM MDT Tue Mar 10 2026

Thursday-Saturday...

High pressure will begin building back in across the region, leading to much warmer and drier conditions for SE Colorado. Steady west-northwest winds aloft will mix down to the surface, resulting in critical fire weather conditions over large portions of our area each afternoon Thurs-Sat. Temperatures are expected to climb well above normal again, with 70s for highs over most areas and near-80 over the far eastern plains.

Saturday night through Monday...

Long range models continue to indicate an upper shortwave crossing the Rockies Saturday, bringing some showers to the central mts and Palmer Divide starting Sat evening, as well as dropping a cold front south across the plains Sat night. High temps for Sunday are forecast to be 25 to 30 degrees colder than those realized on Saturday, with continued cool but seasonal temps on Monday. Something to watch for and be aware of.
