An upper-level weather systems will continue to slowly move across the state of Wyoming and interact with some lingering monsoonal moisture today.  Expect early sunshine and then clouds will thicken during the afternoon and evening hours.  There will also be a chance for isolated showers and thunderstorms, mainly across western and southern Wyoming.  Any storm that develops could be strong and capable of producing hail, gusty winds, and brief periods of heavy rain.  Temperatures will also be warmer and closer to average statewide, with daytime highs in the upper 70's and 80's.  A ridge of high pressure will then build over the region this weekend.  Expect sunny to mostly sunny skies, but we still cannot rule out a few isolated showers and thunderstorms due to lingering low-level moisture and daytime heating.  Temperatures will also remain warm and close to normal, with daytime highs in the 80's to lower 90's.
