KEY MESSAGES

- Temperatures fluctuate from near normal to above normal by late in the workweek.

- Other than a couple rounds of snow showers in the northern mountains conditions remain dry for most locations this week.

- A stronger weather system could impact holiday travel across the Intermountain West this weekend, but details still remain unclear.

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 SUNDAY/

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 /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1021 AM MST Mon Nov 24 2025

MVFR ceilings are hanging on at a few terminals early this afternoon with some mid-levele ceilings elsewhere. Ceilings will continue to scatter out this afternoon with winds up to 5-10 knots. A front moves through from west to east tonight bringing a northwesterly wind shift and stronger than normal nocturnal winds. Precipitation is not expected to impact most terminals. Light snow with minimal, if any, impacts is possible at the terminals adjacent to the Park Range.
