An upper-level weather system and cool front will slowly approach the state of Wyoming today.  This weather system and cool front will then become stalled over the region on Friday and Saturday.  For today, expect partly to mostly cloudy skies with breezy to gusty winds statewide.  Scattered rain showers and a few thunderstorms are expected in western Wyoming, while isolated showers and thunderstorms will be found elsewhere.  Temperatures, however, will remain mild and above the average for this time of year.  Expect daytime highs in the 60's and 70's, with some lower 80's in the eastern plains.  Cloudy, overcast skies with rain showers will then be likely on Friday and Saturday.  Heavy rain will also be possible at times, mainly Friday night into Saturday.  Temperatures will become cooler and closer to average statewide on Friday.  We will then see unseasonably cool temperatures on Saturday.  A cool and very unsettled weather pattern continues for the end of the weekend through the first half of the work week.
