Wyoming wakes up under a crystal-clear sky and a brutal 1-degree freeze in Riverton, and the cold bites instantly. Wind chills have dipped near 15 below zero. Frost coats windshields, and exhaust hangs low in the still air.
According to the National Weather Service in Riverton, sunshine will push highs to 36 degrees this afternoon. Light southwest winds stay under 10 mph, helping conditions improve on main roads by midday. Still, shaded spots and bridges can stay slick through late morning.
Temperatures drop back to around 5 degrees tonight under partly cloudy skies. That sets up another hard freeze by early Sunday. Any meltwater from today’s thaw can refreeze quickly after sunset. This is prime flash-freeze season across Fremont County.
Sunday warms to 43 degrees with increasing sunshine. Clouds build Sunday night, but the bigger shift arrives Monday. Highs surge to 52 degrees under partly sunny skies, marking a dramatic rebound from this morning’s Arctic start.
The warming trend peaks Tuesday with highs near 58 degrees. A slight chance of showers develops Tuesday night, with lows near 30 degrees. If temperatures hover close to freezing, a brief rain-snow mix cannot be ruled out in higher elevations.
Wednesday stays breezy with a slight chance of rain and snow showers before midday. Highs reach 55 degrees before cooler air returns late.
Long-range signals show above-normal temperatures lingering into late next week, with 50s holding steady. After today’s deep freeze, spring warmth is knocking on central Wyoming’s door.
