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 235 AM MST Wed Feb 4 2026

IR Satellite loop early this morning shows dissipating cloud cover across the Front Range and eastern high plains as the Pacific disturbance moves into the southern Great Plains. Clear skies are expected with seasonable temperatures in the upper teens to mid 20s.

Tranquil weather expected today and Thursday as all models continue to show the strong upper level high/ridge axis across the Great Basin region drifting eastward into the Rocky Mountain region over the next 24 to 48 hours. Expect another warming trend, with high temperatures returning to the mid 50s to mid 60s. Can't rule out a few locations across western Nebraska approaching 70 (F) Thursday afternoon with 700mb temperatures close to +3c above the surface. Record high temperatures are possible at most locations Thursday afternoon, including Laramie and Rawlins with forecast 700mb temperatures above the 90th percentile. Winds will also be relatively light Thursday afternoon with gusts generally below 25 MPH, so a pretty nice day is expected for early February standards. The only minor concern will be patchy fog each morning across central and south central Wyoming as the upper level high moves over the area. Right now, did not include fog in the forecast with probabilities generally below 20%.

LONG TERM /FRIDAY THROUGH TUESDAY/

Issued at 324 PM MST Tue Feb 3 2026

The long term remains mostly on track, characterized by remarkably benign weather. A persistent upper-level ridge over the western half of the country will lead to dry and mild weather across the CWA. Precipitation chances will be nearly non-existent through the end of the week and into the weekend as subsidence under the ridge keeps condiitons dry. Dry air aloft will also aid in mostly sunny skies throughout this time period. Well above average temperatures are also expected to persist across the forecast area during this time period. 700 mb temperatures will be in the 90th percentile and above according to NAEFS climatology. This will lead to high temperatures about 20 degrees above average across the CWA. Highs for most locations will be in the 50s and 60s, leading to pleasant, but far from seasonal conditions. Several high temperatures records will likely be tied or broken between Friday and Sunday. Besides record warmth, brief elevated to high winds could be possible in the usual southeast Wyoming wind prones Saturday morning and again on Sunday night thanks to a few weak systems moving across the area. In-house guidance is still only showing elevated winds at this time due to increased MSLP gradients across the Laramie Range. Models hint at the potential for precipitation returning to the CWA next week.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 445 AM MST Wed Feb 4 2026

Northerly flow will continue over the next 24 hours as a strong ridge of high pressure drifts east across the Great Basin Region.

HAZARDS/WEATHER TRENDS: VFR conditions will continue over the next 24 hours with dry conditions. Northwest winds will occasionally gust 20 to 25 knots late this morning through this afternoon, and then diminish around 00z Thursday.
