.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 138 PM MST Mon Nov 24 2025

Mostly clear skies and dry weather will prevail through the
afternoon as drier, northwesterly flow settles into our region.
A shortwave trough passing mostly to our north, and an
associated cold front that will drop into the region, in
addition to the orographics from northwesterly flow, will
support snowfall in the northern and central mountains tonight.
The timing of the snowfall will align with the timing of the
cold front, as low atmospheric moisture means the additional
lift from the front is important. Given the limited moisture,
not much is expected in terms of accumulating snow, but at most
a few inches are possible in the highest elevations of the Park
Range. Other areas of the northern mountains, and the central
mountains, are expected to get less than an inch of accumulating
snow, if any at all. Snow should end by the early morning
hours. Fog may once again impact some valley areas overnight.
The front passage will drop high temperatures by a few degrees
tomorrow when compared to today, but otherwise expect another
mostly sunny and dry day tomorrow. Overnight Tuesday into
Wednesday another round of light snowfall is possible in the
northern mountains as northwesterly flow continues, and a weak
wave of energy passes.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 138 PM MST Mon Nov 24 2025

We remain under a northwesterly flow regime through late in the
week with seasonal to slight above normal temperatures and mostly
dry conditions. Periodic flurries are possible over the northern
mountains at times due to favorable orographic lift, but measurable
snow is not anticipated at this time.

A pattern change arrives Friday/Friday night through the weekend as
a broad upper-level trough passes through the western CONUS. This
system`s timing and impacts remain unclear at this time due to model
differences, but in general we are looking at mountain snow,
precipitation in the valleys (rain? snow? mix?), and cooler
temperatures. One model solution calls for little to no impacts
until Saturday night while others have a round of precipitation
Friday night into Saturday and another round late Sunday into
Monday. Timing will be of the essence with holiday travel in full
swing so we will continue to provide updates as the week
progresses.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 439 PM MST Mon Nov 24 2025

Mostly VFR conditions will continue across western Colorado and
eastern Utah tonight. Stratus ceilings in KDRO are expected to
continue overnight though. A passing trough of low pressure
working across northwest Colorado tonight will bring some mid
level ceilings to areas along and north of I-70 and as far south
as KASE. This is expected to keep lower ceilings from forming in
the moisture laden valleys like KASE. Skies should clear out
Tuesday afternoon for most of the region, with light terrain
influenced winds through the afternoon.
