Cheyenne, Wyoming – Severe thunderstorms may develop across Wyoming by Wednesday afternoon as warm temperatures peak ahead of an incoming cold front, raising concerns for hail, gusty winds, and localized flooding.
According to the National Weather Service in Cheyenne, isolated to scattered thunderstorms are possible each day this week, but Wednesday is expected to bring the most active and potentially severe weather. Highs will climb into the mid-60s and low 70s across the state’s eastern half, including along the I-25 corridor, before colder air pushes in Thursday morning.
Cities like Cheyenne, Torrington, and Wheatland could see storm development by late Tuesday, with Wednesday bringing the highest risk for severe weather. Cooler temperatures will follow Thursday, especially in higher elevations, where snow showers may develop. By Friday and Saturday, showers and thunderstorms return as daytime highs hover in the 50s and 60s.
Residents should monitor alerts closely and prepare for rapidly changing conditions, especially on Wednesday. Charge devices, secure outdoor items, and avoid unnecessary travel during storms.
Further updates on severe weather timing and impacts are expected over the next 24–48 hours as confidence in the forecast increases.
