.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 1239 PM MST Mon Dec 22 2025

The main story today and tomorrow is record high temperatures due to
an expansive ridge building over the central US. This means
temperatures that are 20-25 degrees above normal. Other than
some passing clouds the southwest flow we are under will remain
dry. More clouds are expected tomorrow so today may be the
warmest of the two.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 1239 PM MST Mon Dec 22 2025

Moisture from an Atmospheric River arrives late Wednesday/early
Thursday bringing rain and snow to the region. Warm temperatures
will limit snow production below 9,500 feet with a bulk of the
winter travel impacts expected above 10,000 feet. The southwesterly
AR feed will favor the San Juan mountains, but all area mountain
ranges are anticipated to receive a dose of rain and snow. A lack of
synoptic forcing will limit valley rain with much of the
precipitation being forced via orographics, with the exception of
the Four Corners region and valleys in the foothills of the San
Juans. Overall, expect a warm, wet, and cloudy Christmas Day with
slippery to hazardous travel over mountain passes.

A lull in the rich moisture is anticipated Thursday night through
Friday with lingering light precipitation. Precipitation rates and
amounts do not look impactful during this timeframe, however there
is a medium chance (30-60%) for re-freeze in the higher valleys
Thursday night.

Cooler air moves in this weekend lowering snow levels and increasing
snow ratios. Another surge of moisture will promote continued wet
weather with increasing chances for light snow in the valleys,
especially overnight. It is too early to dive into the details of
this system, but folks with weekend travel plans will want to keep a
close eye on the forecast as the week progresses.

tomorrow with thickening clouds limited mixing in the
afternoon.
