Old Man Winter is making his first appearance of 2026 in southeast Wyoming this week.

That includes subzero wind chills, snow squalls, and heavy snow at higher elevations, with up to 15 inches possible in the Sierra Madre Range and eight inches in the Snowy Range.

While Cheyenne and Laramie can only expect light to moderate snowfall, snow squalls are possible, especially in Laramie, and both communities can expect wind chills that may fall below zero on Thursday.

That's according to the Cheyenne Office of the National Weather Service. The agency posted the following on its website:

Snow will develop west of the Interstate 25 corridor today and spread east into the high plains this evening and tonight. A few snow squalls are also expected between Rawlins and Cheyenne. Moderate snow accumulations are more likely north of Interstate 80 into Thursday morning where a Winter Weather Advisory has been issued. Periods of heavy snow will continue for the Sierra Madre and Snowy Ranges through Thursday morning where ongoing Warnings and Advisories will continue.
