CHEYENNE, Wyo. — A brief warm spell will bring near-average to above-average temperatures to southeast Wyoming today and Thursday. Sunny skies and breezy conditions will prevail, with a high near 44 today in Cheyenne. Winds from the west-northwest are expected to reach 15-20 mph, with gusts up to 30 mph. Tonight, temperatures will drop to a low near 23 under mostly clear skies.
Thursday is forecast to be the warmest day of the week, with highs reaching the low 50s in many areas. However, winds will pick up, particularly in wind-prone areas, where gusts may exceed 50 mph. The National Weather Service out of Cheyenne has issued a High Wind Watch for Thursday into early Friday.
An arctic cold front is expected to arrive Friday morning, bringing a sharp drop in temperatures and increasing snow chances. The NWS predicts widespread light to moderate snowfall, with accumulations of 1 to 4 inches possible in southeast Wyoming, and higher amounts in mountainous regions. Snowfall will likely begin Friday afternoon and continue into the evening, with gusty winds potentially causing areas of blowing snow and reduced visibility.
This weekend will usher in frigid temperatures, with highs in the single digits to teens on Saturday. Light snow may linger into Sunday, with a reinforcing shot of arctic air potentially arriving Sunday into Monday. If the second front materializes, dangerously cold wind chills and even colder temperatures are possible early next week.
