Cheyenne, Wyoming – A fast-moving warmup will push temperatures across Wyoming 10 to 20 degrees above normal by Friday afternoon, increasing snowmelt and creating shifting conditions on rural roads and waterways.
According to the National Weather Service Climate Prediction Center, there is a 70 to 80 percent probability of above-normal temperatures statewide through early next week. Southeast Wyoming, including Cheyenne and Laramie, will see the most noticeable jump in daytime highs.
Cheyenne is expected to reach the upper 60s to low 70s by Saturday, with peak warmth between 2 p.m. and 5 p.m. Along the I-25 and I-80 corridors, dry conditions will dominate, while central and western areas such as Casper and Rock Springs warm into the 60s. Higher elevations will also see a steady rise in temperatures, accelerating snowmelt in the Rockies and increasing runoff into creeks and rivers.
This warming trend ties Wyoming into a broader western heat dome impacting Colorado, Utah, and Idaho. While most areas remain dry, a few isolated showers could develop late in the day across eastern plains, bringing brief gusty winds.
Residents should stay alert near fast-moving water and prepare for rapidly changing conditions between morning cold and afternoon warmth. The heat surge will persist through the weekend into early next week, with additional updates possible as conditions evolve.
