Chance For Rain/T-Storms Across Western & Southern Wyoming, Mostly Sunny & Dry Elsewhere
A ridge of high pressure will build over the entire state of Wyoming for the rest of today. This will allow temperatures to become warmer and well above normal statewide, with daytime highs in the 60's and 70's. Some lower 80's will also be possible in the eastern plains. Subtropical moisture, however, will begin to be transported into parts of the state as a low pressure system approaches the region. Expect partly sunny skies with isolated to scattered showers and thunderstorms across western and far southern Wyoming today and overnight. Elsewhere, we will see mostly sunny skies and mainly dry weather conditions. A large and slow-moving weather system and cool front will then approach the region on Thursday and will continue to move across the state on Friday and Saturday. For Thursday, expect thickening clouds with late-day showers and thunderstorms. Temperatures, however, will remain very mild to warm and above normal. Cloudy, overcast skies and rain showers will then be likely on Friday and Saturday. Temperatures will become noticeably cooler and closer to averag on Friday and then even cooler and well below average temperatures will arrive on Saturday.
