KEY MESSAGES

- Scattered snow showers are expected this morning before conditions clear up this afternoon.

- Snow covered and icy roads could cause hazardous travel this morning.

- Dry air returns by Sunday night with above normal temperatures returning to the forecast by mid week.

SHORT TERM /THROUGH MONDAY/

Issued at 1257 AM MST Sun Dec 28 2025

A trough and the associated cold front is currently tracking southeastward over the area. Temperatures are dropping rapidly behind the front and there is just enough moisture for moderate snow showers along and north of I-70. These showers will continue through the morning with improvements this afternoon. The front might not have much impact across the southern third of the area. Snow showers could linger in the highest elevations through the early afternoon before dry air takes over. Snow covered and icy roads could impact travel this morning. Mostly clear skies tonight along with this new air mass means chilly temperatures. Dry northwest flow continues on Monday and warm advection begins to work away at the cold air mass in place.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 208 PM MST Sat Dec 27 2025

Weak moisture advection will increase PWATs on Tuesday, primarily north of I-70, but a lack of forcing will keep precipitation chances near zero. Ridging will persist through midweek, keeping chances of unsettled weather out of the forecast until the end of the workweek. There is some model suggestion of a strong moisture push towards the weekend, but confidence is very low at this point as model disagreement is significant. High temperatures will be near normal on Monday, but will climb to 10 degrees above normal by Wednesday, and remain well above normal through the remainder of the long term.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 401 AM MST Sun Dec 28 2025

Scattered snow showers will continue through late morning. Cigs and vis may occasionally drop to IFR/MVFR or ILS conditions. Additionally, ILS breakpoints are likely to be reached at these terminals. Winds may gust to 20-25 knots across the region. Mechanical turbulence and mountain obscuration will be additional concerns until skies clear by this afternoon with VFR conditions returning to the region.
