CHEYENNE, Wyo. — A red flag warning is in effect today for parts of southeast Wyoming due to low humidity, gusty winds and hot temperatures. Scattered showers and thunderstorms may develop by mid-afternoon and continue overnight, bringing strong, gusty winds but limited severe weather potential.
Today’s temperatures will be mild in the morning, with some areas still in the 60s and 70s, according to the National Weather Service in Cheyenne. As the day progresses, expect hot September temperatures, particularly east of the Laramie Range. A shortwave from the Pacific Northwest is expected to bring some lift, likely triggering showers and storms by mid-afternoon.
A cold front will move through overnight, leading to lower temperatures on Wednesday. Highs will be around 10 degrees lower than today, with widespread cloud cover keeping things cool. Scattered clusters of showers and storms are likely, with moderate to heavy rain possible. Severe weather is unlikely, but small hail and gusty winds may occur.
Thursday will see continued precipitation chances as a short-wave trough moves through, with temperatures ranging from the upper 60s to low 80s. By Friday, conditions will become warm and dry again, with temperatures gradually rising through the weekend.
