Wyoming — A crisp, frosty start grips central Wyoming this morning, with a light freeze settling across Riverton and nearby valleys.
According to the National Weather Service, temperatures dipped to near 34 degrees early this morning, with some low-lying and sheltered areas closer to 32 degrees before sunrise.
This is part of a broader spring pattern where clear skies and dry air allow rapid overnight cooling across the high plains.
The most immediate impact window stretches through 9 a.m., when patchy frost and brief slick spots may linger on bridges and rural roads, especially along US-26 and WY-789. Low-lying areas near the Wind River and open fields are most vulnerable to cold pooling, increasing the risk of thin ice in shaded stretches.
Gardeners across Riverton, Lander, and Shoshoni face another concern. Sensitive plants may see frost damage if left uncovered during these early morning hours.
Conditions shift quickly by midday. Sunshine pushes temperatures into the mid-60s, drying roads and improving travel conditions.
Another cold drop follows tonight, with lows near 32 degrees again. Expect a repeat frost risk early Saturday, especially in sheltered valleys and rural drainage areas.
The weekend trends warmer and more stable. Highs climb into the low to mid-70s by Saturday and Sunday, bringing a brief stretch of classic spring weather.
By Monday into Tuesday, changes return. Scattered showers and isolated thunderstorms develop, with gusty winds over 20 mph possible. While severe storms are not expected now, lightning and brief downpours could affect travel.
Plan for freezing mornings now, then prepare for shifting conditions early next week as spring storms begin to re-enter the region.
