KEY MESSAGES

- Locally strong gusty winds possible over the wind prone areas of southeast Wyoming late tonight and Saturday morning. Gusts over 50 MPH are expected.

- Mostly quiet weather expected next week, with a cold front pushing through Tuesday and dropping temperatures back into the 40s and 50s.

SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 151 PM MST Fri Jan 30 2026

There is a low pressure system that is moving across the Canadian providences tonight into Saturday. This system will help push the arctic high further east and allow for warmer temperatures to push into the Nebraska Panhandle as the Upper level ridge regains control of the Intermountain West. This afternoon there is some warm air advection moving over the Panhandle increasing the synoptic lift and creating the light stratiform snowfall we are currently seeing across the Nebraska Panhandle. Another front is progged to move across the region allowing for increased chances of light snowfall to continue through the overnight hours across the Panhandle. Accumulations look minuscule to maybe get a light dusting during the overnight hours. The overnight temperatures look to drop into the teens and low twenties across the Panhandle with mid to high twenties across Southeast Wyoming. Due to the mostly cloudy to overcast cloud cover, the overnight temperatures may be warmer than forecast as the low to mid level clouds trap and reflect the longwave radiational waves emitted by the earth's surface at night. Following the front, warm air will gradually push east raising surface temperatures into the 50's for the lower elevations east of I-25 and a little bit cooler of mid to upper 40's west of I-25 in the higher elevations. As the ridge and warmer air really start to push east the subsident flow caused by the ridge will help clear out the sky and the snowfall should end around early to mid morning for most areas in the Panhandle. Overnight temperatures for the overnight period look to fall into the mid to upper twenties for Saturday Night.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 151 PM MST Fri Jan 30 2026

Not many value added changes will be forthcoming this afternoon as the long term period appears to be generally quiet. The period does begin with a highly amplified upper pattern in place characterized by stout upper ridging over the the western CONUS and subsequent downstream troughing over the east. Guidance continues to show high temperatures both Sunday and Monday 10 degrees or more above the climatological average.

The ridge will be knocked down for a few days(Tuesday and Wednesday) behind a cold front forecast to move through early Tuesday. The cold front itself is rather non descript and with little moisture to work with, will likely only produce a little light snow in the higher terrain areas. High temperatures across the forecast area on Tuesday and Wednesday will still make it into the 40s to lower 50s in the lower elevations with 20s and 30s in the high country.

The upper ridge rebuilds quickly over the four corners behind this front. Heights on Thursday support high temperatures in the 50s and possibly lower 60s the lower elevation areas on Thursday with only slightly cooler readings on Friday as a cold front approaches.

While the period does appear to be quiet, the one exception may be Friday with some of the longer range guidance suggesting some strong winds associated with the aforementioned cold front. Impressive H7 jet associated with an upper low diving into the Great Lakes could help generate gusty winds but as we are taking a week out, a wait and see approach will be taken.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 1040 PM MST Fri Jan 30 2026

Freezing fog has moved in across southeast Wyoming, impacting KCYS with VLIFR conditions. Expect this to continue over the next several hours with FZFG diminishing around 09Z. Elsewhere, low CIGs of less than 2,000 feet have been plaguing the terminals across the Nebraska panhandle all afternoon and evening. CIGs should begin to lift around 09Z as a system, that brought light snow earlier today, moves out of the area. Thereafter, VFR conditions will return and prevail across all terminals for the remainder of this TAF period. Winds in general will pose little to no threat to aviation operations; however, gusty winds of 20-30 knots ramp up tonight into Saturday morning. This is short-lived as winds will decrease to less than 10 knots across all terminals by 02Z Sunday.
