A stationary trough of low pressure over the west coast will continue to transport moisture and atmospheric instability into the state of Wyoming today.  This weather system will slowly move east into the region on Friday, Saturday and Sunday.  A cool front will also dig south into the state late Saturday into Sunday.  For today, expect partly to mostly sunny skies, breezy to gusty winds, and a few hit-or-miss showers and thunderstorms.  Any storms that develop could be capable of producing small hail, gusty winds, and lots of lightning, especially in southeastern parts of the nation.  Temperatures will be warmer and near or slightly above normal, with daytime highs in the 60's and 70's.  We will see cloudy to mostly cloudy skies and a better chance for showers and thunderstorms on Friday, Saturday and Sunday.  Rain could become heavy at times and create minor areas of flooding.  Temperatures will become cooler and below normal during this time.  Daytime highs in the 40's and 50's, with some lower 60's on the far eastern Plains.
