KEY MESSAGES

- Warmer than average temperatures and mainly dry conditions for the next week outside of a weak frontal boundary Monday.

- Minimal snow chances (10-20%) for the northern Bighorns and points east Monday evening with a weak system with the main impact of increased clouds and temperatures not quite as warm.

DISCUSSION

Issued at 1200 AM MST Sat Jan 31 2026

WV imagery depicts a strong upper level ridge across much of the western United States with IR showing the mid and upper level clouds spilling in across much of the state. The weak system that pushes through earlier Friday will push further east with any weak showers across eastern counties doing so as well by sunrise Saturday morning. Otherwise, high pressure builds strongly in from the west through the day as skies clear west to east by late morning and into the afternoon hours. Relatively light winds outside of some breezy conditions for the wind corridor, especially for northern Johnson out of Sheridan County, and warming temperatures. Temperatures expected to be 10 to 20 degrees above average for this time of year to start the month of February, even west of the Divide. Widespread 50s to near 60 to the east Monday onward.

The only thing of note in the long term forecast will be a weak system and associated cold front will push through Monday. This will knock well above average temperatures Tuesday to just above average 5 to 15 degrees. Otherwise, cloudy skies and breezier conditions to be had Monday with slight snow chances (10-20%) for Monday evening and through the overnight hours into Tuesday for the northern Bighorns and points east across Johnson County. Outside of this weak chance for precipitation, nothing can be seen on the horizon through at least the first week of February with longer term model solutions indicating the strong upper level ridge to be in place with ample convergence aloft to support it.

Gusty winds will develop at the favored southwesterly flow locations, mainly from KRKS to KCPR with gusts to near 30 knots likely this afternoon. A gusty west wind in vicinity of KCOD should decrease through the morning hours. The drainage wind in vicinity of KRIW will decrease around sunrise. Otherwise, expect wind to be generally 12 knots or less through the period for all TAF sites.
