KEY MESSAGES

- A warming trend begins tomorrow, with temperatures climbing to 10-15 degrees above normal by mid-week.

- Favored cold pool valleys, including the Gunnison and Yampa river valleys, will see another chilly night.

- Quiet conditions persist through the week, with a chance for cooler temperatures by next weekend.

SHORT TERM /THROUGH MONDAY/

Issued at 328 PM MST Sun Jan 11 2026

A weak upper level system well to our south is cutting underneath the ridge building across the West this afternoon. This has pulled some moisture across the Great Basin, leading to a shield of high clouds blotting out the blue skies we saw this morning. This will cap out our afternoon highs, leaving us near normal for the day. Cloud cover pushes south tonight as the cutoff low tracks east. This should let cold basins in the Yampa and Gunnison, radiate out efficiently. Stuck with persistence there on temperatures, with a slight bump upward, given the aging snowpack. Note: I left Silverton and the Animas Basin alone, given the resident cloud cover likely to cap them tonight.

Another chilly start will kick off Monday, but subsidence under the high will drive up heights and temperatures Monday afternoon. Highs will trend about 10 degrees above average under clear and sunny skies. This will return a familiar pattern back to the region.

LONG TERM /MONDAY NIGHT THROUGH SUNDAY/

Issued at 328 PM MST Sun Jan 11 2026

Warm days, cool nights, and dry conditions continue through the seven-day forecast with high pressure remaining centered to our west. Flurries cannot be ruled out over the northern mountains from time to time with persistent north/northwest flow aloft. Otherwise, a very benign weather week is on tap.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 941 PM MST Sun Jan 11 2026

Scattered to broken high cloud cover is pushing south of I-70 and should remain across southeast Utah and southwest Colorado overnight with clearing skies along and north of I-70. Mostly clear skies should take over area wide by Monday afternoon. Winds will remain light and terrain driven through the period with VFR conditions.
