High pressure will be the main weather feature across the state of Wyoming through the afternoon hours.  Expect mostly sunny skies, breezy to gusty winds, and mainly dry weather conditions statewide.  Temperatures will also stay cold and below normal, with daytime highs staying in the teens and 20's.  An upper-level weather system will slowly move across Colorado today and then approach the CO/WY state line by the evening and overnight hours.  This could create a few flurries or light snow showers across central and southeastern Wyoming tonight.  No new snow accumulation is expected and travel should not be impacted by this weather system.  There could be a few more additional flurries or light snow showers early on Friday morning.  Otherwise, expect a mix of sun and clouds and mainly quiet weather conditions throughout the state.  Temperatures will be a few degrees warmer for the end of the week, but it will still be cold and below average.  An Arctic cold front brings even colder temperatures and a better chance for snow on Saturday.
