KEY MESSAGES

- Multiple arctic cold fronts will bring much colder temperatures to the area through Sunday, with the coldest wind chills on track for Friday.

SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 156 PM MST Fri Jan 23 2026

Radar and observations across the CWA show widespread light snow early this afternoon. Snow will continue through the afternoon hours with accumulations generally under an inch possible for areas east of the Laramie Range. Further west, steadier upslope flow has lead to snow and poor visibilities in the Arlington area. Accumulations between 1 and 3 inches will be possible, so went ahead and issued a Winter Weather Advisory through the overnight hours. This evening, snow will taper off gradually from north to south. Bitterly cold air will remain in place tonight, with low temperatures below zero. Overnight, wind chills will be much colder, ranging from -20F to -30F in areas already in a Cold Weather Advisory.

The cold wind chills will continue through the morning hours on Saturday as clouds clear out of the area. Although temperatures aloft will remain virtually the same, ample sunshine during the afternoon will allow highs to warm into the teens. This will also lead to a break from the cold wind chills, allowing the Cold Weather Advisories to expire by the afternoon. Aside from a possible few lingering snow showers in the morning, precipitation chances are not expected for the remainder of the day. Heading into Saturday night, the cold temperatures return with most locations experiencing low temperatures below zero. With little wind to speak of overnight, wind chills will be a bit more tame, falling into the negative teens. Increasing cloud cover is also expected overnight ahead of a reinforcing shot of cold air. This secondary arctic front could start to push into the northern reaches of the CWA late Saturday night, leading to another round of light snow.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 156 PM MST Fri Jan 23 2026

The cold lingers through Sunday to start the long term as morning lows continue to sit in the low single digits to negatives, while highs struggling to get out of the teens for the day. Meanwhile a passing system should help to produce another round of snow for the region, but once again a lack of more significant moisture should preclude us seeing much more than an inch or two across most zones. Lows descend similarly on Monday morning, but as ridging takes over the western US once again temperatures will rebound back to near normal or just under on Monday, with highs in the 30's to low to mid 40's through the remainder of the week. Pressure gradients tighten on Monday though and bring another round of high winds, which will likely be the primary hazard in the long term. In house guidance has dropped a little bit, with probabilities now 60-75% for the wind prone locations to see high wind gusts (58 mph) or greater, which are still high enough to encourage the need for High Wind products as we approach Monday. Thereafter, some passing systems may continue to promote breezy winds, but the main moisture should remain just outside of our region, with dry conditions and benign conditions otherwise.

AVIATION /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 434 PM MST Fri Jan 23 2026

Light snow moving across the region is impacting many terminals across the CWA, except KRWL and KCDR, with a mix bag of flight categories from MVFR to as low as LIFR. CIGs have dropped to around 1K feet while VIS varies depending on the intensity of snow and any obscurations. This is expected to continue into the overnight hours before coming to an end by 12Z Saturday as all terminals should return to VFR conditions. Winds will diminish overnight to generally less than 10 knots and remain at this speed to round out the TAF period.
