A passing weather system will combine with monsoonal moisture to trigger shower and thunderstorm activity throughout the state today.  Shower and thunderstorm activity will be likely across the western, northern and southern mountain areas (and higher terrain), while mainly isolated thunderstorms will be possible throughout eastern Wyoming.  However, any storms that do develop have the ability to produce small hail, gusty winds, and heavy rain at times.  Expect partly cloudy skies with very mild and seasonal temperatures statewide today.  Daytime highs will remain in the 70's to mid 80's.  Chances for showers and thunderstorms continue through the upcoming weekend.
