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.

- Some record high temperatures expected Today, Friday, and possibly through the weekend.

- Locally strong winds possible for the Wind Prone areas of southeast Wyoming late Friday night and Saturday morning.

SHORT TERM /THROUGH SATURDAY/

Issued at 346 PM MST Thu Feb 5 2026

A pleasant afternoon continues across the forecast area with a mostly cloudless sky and well above average temperatures in the 50s and 60s. Some locations will have the potential to set new record high temperatures this afternoon. This will be revealed a little later today with the evening run of the climate product.

Above average temperatures will continue into the day Friday as the upper-level ridge axis sits directly over the CWA. Even warmer temperatures will exist aloft due to stronger warm air advection, however models show high temperatures being a few degrees cooler than today. This is likely due to a strong inversion that soundings show taking most, if not all day to mix out. Regardless, temperatures will still be mild with highs reaching the 50s and 60s once again. Precipitation chances once again remain non-existent with subsidence keeping skies clear. Winds will begin to increase Friday night as the ridge axis moves out and a weak disturbance moves in.

Saturday will start off windy, particularly in the wind prones. The weak disturbance will cause MSLP and height gradients to steepen, increasing winds aloft up to 50 kts over the usual southeast Wyoming wind prones. In-house guidance shows these sites briefly hitting high winds, but with only a 40 percent chance of occurrence. Held off on issuing any products at this time as confidence is low. Would like to see a stronger MSLP gradient over the Laramie Range at the time of peak winds aloft to see high winds at Bordeaux and the South Laramie Range. Have more confidence in the Arlington zone hitting criteria with CAG to CPR 850 mb height gradients reaching 50 meters. Subsidence is strong, but does not necessarily line up with where the strongest winds aloft are. The windy conditions will help aid in another warm day on Saturday. Downsloping winds will bump temperatures into the 60s for areas east of the Laramie Range. There could be some mountain wave clouds around in the morning, but these will likely clear during the afternoon as winds gradually weaken. Overall, a breezy, but pleasant day.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/

Issued at 346 PM MST Thu Feb 5 2026

Not many changes will be forth coming this afternoon as guidance has not really altered that much from previous thinking. There are some differences between the GFs and ECMWF that are note worthy and would have an impact on our sensible weather. These differences do not really show up until late in the period so plenty of time to get some clarification.

The period initiates with the highly amplified pattern we have all become familiar with in place with ridging over the CWA, anchored by upper troughing along the east coast and another trough approaching the west coast. The ridge will dominate on Sunday with temperatures still well above average with highs in the upper 50s to mid 60s, cooler of course in the higher elevation areas. Elevated winds can not be discounted Sunday night but no headlines are expected. The ridge will start to flatten out somewhat Monday but temperatures will still be comparable to Sunday's.

Guidance continue to show a cold frontal passage Monday night and into Tuesday which will knock down temperatures considerably and introduce at least a chance of much needed moisture, especially in the higher terrain areas. Actual POPS and QPF are not excessively high but any precipitation would be welcomed.

The aforementioned model differences show up after the cold frontal passage with one solution developing yet another stout upper ridge over the area with a weak wave sneaking through it. Another solution has a much broad and flatter ridge to our south with much better chances of precipitation. Which solution does verify will be significant to precipitation chances and amounts but plenty of time remains to sort it all out.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1020 PM MST Thu Feb 5 2026

No aviation weather concerns across all terminals as VFR conditions will prevail for the duration of this TAF period under a stout ridge of high pressure. Winds will pose limited to no impacts as well as they become south/southeasterly around 10 to 15 knots by Friday afternoon.
