Subtropical moisture from the south will approach the state of Wyoming today, which will keep skies partly to mostly cloudy statewide.  This could also create a few flurries or light snow showers across far southern Wyoming later this evening and overnight.  Expect some isolated slick spots over the higher elevations of I-80, mainly near Elk Mountain and over the Summit.  Otherwise, conditions stay mainly quiet and there will be no other major travel concerns.  Temperatures will also remain cool and close to average today, with daytime highs in the 30's and 40's.  Moisture will continue to move into the state on Saturday and create a chance for flurries or light snow in southern Wyoming into Saturday morning.  Expect more clouds than sun and seasonal temperatures throughout the state for the rest of the day.  A Canadian cold front will then push south into Wyoming Saturday night into Sunday.  This will create a better chance for snow for much of the state.  Slick and icy roads will be possible across central and eastern Wyoming and visibility could also be reduced at times overnight.  Significantly colder temperatures arrive on Sunday and there could also be a few lingering flurries or light snow showers.
