RIVERTON, Wyo. – Under a bright moon and cool, still air this Thursday morning, central Wyoming begins one of its last mild stretches before winter’s edge creeps closer. Roads are dry, skies are clear, and the calm hides what’s coming—a subtle but steady shift toward colder, more unsettled air by late weekend.
According to the National Weather Service in Riverton, mostly sunny skies will hold through Friday with pleasant highs in the lower 60s. Winds remain light, ideal for travel across Fremont County and the Wind River Range foothills. Friday afternoon brings the peak of this mini warmup before a developing trough approaches from the west. By Saturday, southerly winds strengthen to 20–25 mph, signaling the next change.
Clouds build through Saturday night, and a few rain showers could mix with snow in higher valleys by late Sunday. Any flakes that fall should be brief and non-accumulating, but this will likely mark the season’s first wintry signal for the region. Travelers on U.S. 26 and I-25 should prepare for gusty crosswinds and temperature drops by Sunday evening.
Behind the system, cooler air settles in early next week. Highs dip into the low 50s Monday with lows in the 20s—perfect conditions for early frost on ranchlands and in low valleys. For now, it’s a picture-perfect late-October stretch: blue skies, brisk mornings, and that growing sense that Wyoming’s first real snow is inching closer to the horizon.
