KEY MESSAGES

- Warming days, cool nights and dry conditions will persist through the weekend and most of coming week.

- There is a chance for light snow showers and breezy winds Tuesday over the northern Colorado mountains with little if any snow accumulation likely.

SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 159 PM MST Sat Jan 31 2026

High pressure moving in over the Desert Southwest with ridging extending up through the Great Basin will continue to track eastward across New Mexico and Colorado Sunday before pushing out onto the Plains and West Texas Sunday night. A couple shortwaves do top the ridge Sunday, but remain too far north to bring anything more than a high clouds to eastern Utah and Western Colorado. Expect mostly sunny skies across the region with periods of high clouds. High temperatures will be 10-15 degrees above normal today and will warm a few degrees tomorrow. Look for the morning lows to run near normal in the mountain valleys to about ten degrees above normal in the lower valleys.

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 159 PM MST Sat Jan 31 2026

Quiet weather is expected through most of the long term period. This is thanks to persistent a ridging over the West through much of the workweek. A disturbance to our north will flatten the ridge, but late Monday ridging builds over the West again as the disturbance moves east of the Rockies. Another disturbance is expected to provide lift to our northern Colorado mountains on Tuesday afternoon. This could allow for some light snowfall on Tuesday. The disturbance will bring a small amount of moisture with it, but this only brings PWATs to around 120% of normal at most. The lack of moisture should keep any snow accumulations to less than an inch, and really only over the Park Range. An increased pressure gradient associated with the passing disturbance could lead to stronger wind gusts Tuesday afternoon. After Tuesday the return of ridging aloft will drive warm and calm weather conditions through the rest of the workweek. Above normal high temperatures are forecasted through the long term period, but temperatures will drop by a few degrees on Tuesday and Wednesday due to the passing disturbance. Highs 10 to 15 degrees above normal are anticipated in the latter half of the week.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 411 PM MST Sat Jan 31 2026

High level clouds will increase across the north tonight, bringing scattered to broken skies. Ceilings remain well above breakpoints. Breezy westerly to northwesterly winds will gradually weaken over the next 2-3 hours, becoming light and terrain driven. VFR conditions will prevail through the period.
