KEY MESSAGES

- High Wind Warnings remain in effect and have been expanded to include central Laramie County and the Laramie Valley.

- Cooler and near normal during the end of the week alongside some passing precipitation chances, with notable warmth by the weekend including temperatures 10-15 degrees above normal.

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 134 PM MST Mon Jan 26 2026

The Intermountain West will remain primarily in Northwesterly flow with a couple quick jaunts to westerly flow as benign shortwaves move through the area through the short-term. The high winds are expected to continue through the day with the max gusts hovering around 75 mph for the wind prones and 65 mph everywhere else. By nightfall the winds will start to lose strength but we aren't expecting those gusts to drop below High wind criteria until after 09z Tuesday. However, for the Plains and valley areas near Laramie and Cheyenne we could start seeing those gusts drop off around sunset when the diurnal mixing stops occurring and boundary layer separation happens. The pressure gradient starts to relax through the overnight period with the Craig to Casper height gradient dropping below 60 meters after 09z Tuesday. With the shortwave pushing into the CWA early Tuesday morning throughout the day should be fairly dry, leading to no precipitation with this system. Behind this system a strong upper-level ridge is developing and will move into the Intermountain West. As a result, warming temperatures and dry conditions are expected to return to the region. Elevated winds look likely during the day Tuesday as 700mb height gradients remain elevated. High winds do not look likely for Tuesday afternoon at this time.

Temperatures overnight are expected to be a little chilly with potential temperatures dropping down into the teens and 20's. With the clear to mostly clear skies tonight, optimal radiational cooling will occur with the coldest temperatures being in both the mountains and far eastern side of the Nebraska Panhandle. For areas closer to the mountains along I-25, temperatures are expected to be a little warmer with the continued aide from our downsloping winds. Temperatures will increase back into the 30s and 40s for much of the area during the day Tuesday and temperatures will once again drop into the teens and twenties for Tuesday night as well.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 134 PM MST Mon Jan 26 2026

The long term will see a quick passing system on Wednesday help to bring our temperatures back down to near normal and promote some breezy winds alongside elevated precipitation chances, but by the weekend we'll see high pressure ridging fully entrenching the Western US, with highs becoming 10-15 degrees above normal at that time. Wednesday starts with a quick shortwave moving across the region, with a secondary and weaker system on Thursday. Overall the impacts from these systems will be fairly minimal, keeping our temperatures near normal while also promoting some breezy winds and passing precipitation chances. With a lack of significant moisture and weak forcing, a few passing snow showers are possible with low accumulations, mostly relegated to the mountains and as well as one or two bands in the Nebraska Panhandle. Models are also unimpressed with our high wind chances, with in house guidance only promoting a 30-50% probability of high wind gusts for our wind prone locations. By the weekend however, the ridge will overspread the entirety of the Western US and cause our temperatures to notably increase, with widespread highs in the mid 40's to mid 50's and drying conditions. With the high increasing it's presence, it will be harder for any passing systems to graze us, also reducing our chances of high winds. If you've been looking for some favorable conditions for outdoor activities, this weekend might be your opportunity.
