RIVERTON, WY — The air across the Wind River Basin feels crisp and still this morning, the kind that smells faintly of pine and distant snow. A stretch of bright, calm weather continues for now — but a subtle winter shift is on the way as the region prepares for Thanksgiving travel and colder conditions early this week.
The National Weather Service in Riverton reports mostly clear skies through Sunday, with highs near 50°F and light winds. These mild days are ideal for outdoor prep — whether clearing yards, hanging lights, or getting vehicles ready for long drives ahead of the holiday.
By Monday evening, clouds will increase from the northwest as a weak Pacific disturbance crosses the state. This system brings a 20% chance of snow showers, mainly for higher terrain west of town and along Highway 26. While accumulations look minor, any quick burst of flakes could coat roads or create brief visibility drops after sunset. Temperatures will dip into the upper teens, signaling the start of a late-November cool-down.
From Tuesday forward, Riverton settles under mostly sunny but colder skies — highs in the 30s and lows near 20°F. Thanksgiving Day looks calm and cool, with highs near 47°F, perfect for early travel or quiet outdoor gatherings.
