KEY MESSAGES

- Dry weather and mild temperatures expected for the rest of the week and into the weekend. Possible change in the weather pattern early next week.

- Near record high temperatures expected Thursday, Friday, and possibly through the weekend.

SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 250 PM MST Wed Feb 4 2026

Little to speak of in the short term as strong upper-level ridging dominates western CONUS. As the ridge axis gradually translates eastward towards Wyoming, warmer and drier air will be advected into the CWA. 700 mb temperatures on Thursday will be above 0C, which is roughly the 90th percentile for NAEFS climatology. This will lead to a mild day across the CWA with highs roughly 20 degrees above average. All locations will likely be within a few degrees of record high temperatures, while a few locations, namely Alliance, Chadron, and Laramie, could potentially break their record. Highs across the area will range from 50s out west, to 60s east of the Laramie Range. Subsidence under the ridge, will keep skies sunny with non-existant chances for precipitation. Overall, it will be a pleasant early February day, but far from seasonal.

LONG TERM /FRIDAY THROUGH WEDNESDAY/

Issued at 250 PM MST Wed Feb 4 2026

At the start of the long term period, ridging will continue its domination of weather conditions across the CWA, leading to no precipitation and mild temperatures. As we progress through the forecast period, ridging will control weather conditions into and through this upcoming weekend. So, expect dry conditions under sunny skies and mild temperatures. With all this talk about temperatures, what can we expect? Well, a surge of warm 700mb temperates will push into the CWA, in the +2 to +4 degree C range, leading to highs soaring to above normal. So, highs Friday through the weekend into Monday will top out in the low/mid 50s degrees F west of I-25 and mid 50s/60s east of the highway, warmer as you go east with the highest temperatures across the Nebraska Panhandle where a few locations may hit 70 Saturday and/or Sunday. During this stretch, we could see a few temperature records being tied or broken. The threat of high winds in the extended remains meager under the dominating ridge, although elevated chances increase across southeast Wyoming Saturday morning into the afternoon hours and once again Sunday night. So, now lets take a quick look at the tail end of the long term where we may see some changes across the CWA. In-house guidance depicts a cold front that will slide south across the region from low pressure coming out of Canada. This will bring increased chances of precipitation and colder temperatures along with an uptick in winds. Plenty of time to monitor and fine tune the forecast, so stay tuned...

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 437 PM MST Wed Feb 4 2026

Winds are going to primarily be west to Northwest tomorrow and about the average gusty-ness for the region (up to 30kts in the afternoon). There will be a low level jet setting up across the Panhandle tonight at around 2,000ft and up to 40kts. This low level jet may bring a wind gusts overnight to the Panhandle sites of up to 25 kts. But it is sometimes harder to mix those winds down for continued nightly gusts over the Panhandle. There will be some high based clouds at 15,000ft and above moving through the region while the airports report skc.
