Cheyenne, Wyoming – A broader warming trend is expected to take shape across Wyoming as February transitions into March, increasing the probability that winter’s harshest cold becomes less persistent statewide during the Feb. 28 through Mar. 13 timeframe.
According to the National Weather Service Climate Prediction Center, Wyoming carries a 33% to 50% probability of above-normal temperatures in the Week 3-4 outlook. The warmer signal spans much of the state, including the Interstate 80 corridor from Evanston to Cheyenne, north along Interstate 25 through Casper, and across Interstate 90 in northeastern Wyoming.
This extended-range guidance favors more seasonable to slightly milder conditions compared to late-February averages. While cold snaps remain possible given Wyoming’s elevation and terrain, the broader atmospheric pattern suggests fewer prolonged Arctic intrusions dominating the High Plains and mountain basins.
Precipitation probabilities during the same period lean near normal across the state. No strong wet or dry anomaly stands out in the long-range outlook, indicating that typical late-winter systems remain possible without a clear signal for excessive snowfall or extended dry stretches.
Communities from Jackson and Riverton to Gillette and Laramie fall within this gradual transition toward early-spring conditions. The Week 3-4 outlook reflects large-scale atmospheric trends rather than specific storm timing or day-to-day weather details.
Additional refinements are expected as the late-February to mid-March window approaches and shorter-range guidance becomes available.
