A slow-moving weather system will move across the state of Wyoming today, Saturday and Sunday.  A cool front will also dig south into the region late Saturday into Sunday.  We will see cloudy, overcast skies with breezy to gusty winds through the end of the weekend.  Rain and thunderstorms will also be likely during this time, especially for central and eastern parts of the state.  Rain could become heavy at times and create areas of minor flooding and standing water on roadways.  Strong to severe thunderstorms will also be possible in far southeastern Wyoming, which could create hail and damaging winds.  Temperatures will be cooler and below normal today and Saturday, with daytime highs in the 50's to lower 60's.  Expect even cooler and well below average temperatures on Sunday.
