Southeast Wyoming gets warm, windy conditions ahead of cooler weather next week

CHEYENNE, Wyo. — Southeastern Wyoming, including Laramie County, will experience seasonably warm temperatures through the week, punctuated by windy conditions and a potential for snow next week, according to the National Weather Service in Cheyenne.

Daytime highs are expected to reach the 50s and 60s, with a brief cooldown Wednesday. Wednesday’s high is forecast in the upper 30s to upper 40s for most areas, and around 50 degrees for locations below 4,000 feet.

Winds are expected to pick up Thursday and into Friday, particularly in wind-prone areas, with calmer conditions returning over the weekend. Gusts could approach high wind criteria in areas like Arlington, Bordeaux and the Interstate 80 summit late Thursday and early Friday, though confidence is limited and a high wind watch has not been issued.

“In-house wind guidance is flirting with high wind criteria for a few of our wind-prone areas for a time late Thursday evening through the early morning hours of Friday prior to sunrise,” the NWS in Cheyenne said in its area forecast discussion.

Friday’s forecast includes concerns for fire weather along the Interstate 25 corridor from Cheyenne to Douglas and along Interstate 80 from Cheyenne to Kimball, with low humidity and west/northwest winds. However, near-surface winds are expected to remain light, precluding red flag conditions.

The weekend will see continued mild and dry conditions, with a potential for high winds in wind-prone areas Sunday.

Next week, a cold front is expected to bring cooler and wetter weather. Rain and snow showers are likely Monday, with snow showers expected Tuesday. The heaviest snow accumulations are expected in the mountains, but lighter accumulations are possible in the Wyoming plains and Nebraska Panhandle.

“The next shot at widespread and/or accumulating precip comes Monday into Tuesday with the upper trough and surface cold front,” the NWS in Cheyenne said.

For Wednesday, the forecast calls for mostly sunny skies, a high near 43 degrees and northwest winds gusting at up to 30 mph.
