KEY MESSAGES

- High Wind Warnings continue through this evening for the wind prone locations of Wyoming, with widespread gusty winds for the rest of the region.

- Warmer temperatures and mostly benign conditions expected Sunday through middle of next week.

SHORT TERM /THROUGH SUNDAY/

Issued at 215 PM MST Sat Jan 10 2026

High wind event ongoing across the region primarily for our wind prone locations though some stronger gusts have been popping up from eastern Wyoming through the Panhandle as the 700mb jet has increased over these regions. While widespread gusts into the high wind warning territory (58+ mph) aren't expected for these zones that are currently not warned, an isolated stronger gust nearing this criteria could be possible through the evening hours. High wind warnings for the usual wind prone locations are set to expire through the evening as conditions weaken through tonight.

Otherwise, the forecast will be largely uneventful as high pressure ridging begins to take over the western US and brings notably warmer than average conditions back to the CWA. Highs today are near normal for this time of year, but into Sunday we'll be back to seeing widespread 50's east of the Laramie Range, with portions of the Panhandle already expected to get back up into the mid to upper 50's. Significant weather concerns after high wind warnings expire will be nil through the remainder of the short term.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 215 PM MST Sat Jan 10 2026

The long term will be characterized as mostly inactive. Tuesday and again could see some light high mountain snow and breezy conditions. Otherwise, dry and cooling conditions expected through the long term period.

Models show an upper level ridge to remain over the region through much of the long term. Tuesday however, models show a weak disturbance that will ripple across the region bringing with it slightly breezy conditions as well as high mountain snow and low elevation rain. As for the winds, 30-50% of the raw ensembles show sustained winds between 25-30 mph with gusts between 35-40 mph primarily along the I-25 corridor between Cheyenne and Douglas with higher probabilities of stronger winds along the ridgetops of the Laramie Range. Same goes for the I-80 corridor between Cheyennes and Rawlins.

Models show a brief timeframe between 5 AM Tuesday and 5 AM Wednesday where some areas will see some light precipitation. However, little to no accumulations are expected. Only 10-20% of the raw ensembles are in agreement. If precipitation does occur, much of it will fall as rain along the lower elevations and snow along the ridgetops. Confidence in any precipitation accumulating is low.

Temperatures will remain above normal as the ridge remains in place overhead through Thursday. In-house guidance shows that the max temperatures will be 10-20 degrees above seasonal normal with the exception of the higher mountain tops. Models show west of the Laramie Range will average temperatures below 50 degrees while the east will average temperatures in the mid to upper 50s with a few isolated locations seeing low 50s.

Models show a cold front headed its way to the area Thursday afternoon/early evening and will likely be accompanied by increased winds again. The cold front will cool the area back towards seasonal normal temperatures. Models are still out of alignment as we move into mid-week with clusters showing the divergence to be with the location of the incoming system. One model wants to bring in a trough while another model just has stronger north to northwest winds. Regardless of that, both are suggesting a decent cool off towards the end of the period. In-house calculations show that by Friday, temperatures could be at or below seasonal average. Models show highs to be in the mid to upper 30s across the entire CWA with moderate (40-60%) confidence in temperatures.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1014 AM MST Sat Jan 10 2026

VFR conditions will persist through the forecast period. Winds will be the primary concern with all locations seeing breezy winds between 15-25 kts with gusts to near 40 kts. Winds will settle at most locations overnight. However, SNY/AIA will see wind shear around 02-03Z at WS020/32040KT.
