CHEYENNE, Wyo. — Cheyenne will experience dry and calm conditions through Friday, with warmer temperatures gradually returning. Highs will climb into the mid-70s to mid-80s today and Friday, with no significant impacts expected beyond fire weather concerns.
A slow-moving Pacific storm system is forecast to reach the area over the weekend, bringing a shift in weather patterns, according to the National Weather Service in Cheyenne. Rain chances increase to around 10% Friday night as the system approaches.
Expect a significant cooldown starting Saturday as cooler Canadian air moves in. Highs could dip into the 50s and low 60s, with beneficial rainfall forecast along the Interstate 80 corridor and eastern areas. Rainfall amounts of up to an inch may help alleviate drought conditions. The first measurable snowfall of the season is possible Sunday at elevations above 10,000 feet in the Snowy Range.
Cooler temperatures will persist into next week, with the potential for another weak front to arrive by Tuesday, keeping daytime highs below average. A warming trend is likely by midweek as an upper-level ridge builds.
