An upper-level weather system and cool front will slowly approach the state of Wyoming today. This will cause clouds to thicken throughout the day and will also create scattered shower and thunderstorm activity later this afternoon and evening. Any storms that develop could be strong to severe and capable of producing hail, gusty winds, lots of lightning, and heavy rain at times. Temperatures, however, will remain very warm to hot and well above normal. Daytime highs will stay in the 80’s and 90’s. A ridge of high pressure will become settled over western portions of the nation on Wednesday, Thursday, and Friday. This will cause a northwesterly flow, which is favorable for creating fast-moving weather systems, to form over the state of Wyoming. Expect partly to mostly sunny skies with isolated to scattered showers and thunderstorms during this time. Temperatures will also be not as hot, with daytime highs in the 70’s and 80’s. Expect hot temperatures and a small chance for showers and thunderstorms on Independence Day.
