An upper-level weather system will quickly move across the state of Wyoming today.  Expect cloudy to mostly cloudy skies, breezy to gusty winds, and seasonably cool temperatures statewide.  High temperatures will remain in the 30's and 40's, with some lower 50's in the far eastern plains.  There will also be a chance for light to scattered rain and snow showers, especially across western and southern portions of the state.  Roads will stay mainly wet across I-80 (Utah to Cheyenne) and adjacent highways, but could become slick, especially after sunset.  Visibility could also be reduced at times.  Elsewhere, expect just a few isolated wet spots.  Higher pressure will then build over the region on Thursday and Friday.  Expect sunny to mostly sunny skies, warmer temperatures, and dry conditions throughout the state during this time.  The only travel concern will be strong winds at times across the more wind prone areas of Wyoming early on Thursday morning.
