RIVERTON, Wyo. – Fall weather takes a sharp turn across central and western Wyoming today as a cold snap moves through the region, bringing scattered showers, gusty winds, and snow above 7,500 feet. Conditions will clear quickly by Friday, setting up a sunny, breezy weekend perfect for outdoor events and travel across Fremont and Natrona counties.
According to the National Weather Service in Riverton, Thursday’s showers and isolated thunderstorms could briefly turn heavy, with small hail possible in stronger cells. Snow levels will fall sharply in the Wind River and Absaroka Mountains, where early-season flakes may dust high passes. Motorists along U.S. 26 and WY-789 should drive cautiously as temperatures drop and visibility fluctuates through the morning hours.
Friday brings a complete turnaround with clear skies, highs near 60°F, and light winds. By Saturday, sunshine dominates again with comfortable highs in the low 60s and calm afternoon conditions—ideal for fall decorating, hiking, or pumpkin patch visits.
The mild weather continues into Sunday before a weak system brings a few showers late in the day. Residents planning mountain travel should prepare for quick changes in elevation temperatures and check for updates from WYDOT on potential slick passes. Warmer afternoons and crisp evenings will return early next week, but the chill in the air serves as a reminder that Wyoming’s winter is edging closer.
