Rain & Snow Expected In Western Wyoming Today, Turning Colder & More Unsettled Statewide on Wednesday

A large trough of low pressure will continue to slowly approach the state of Wyoming today and will become settled over the region on Wednesday, Thursday, and Friday.  This will cause a series of cold fronts and weather disturbances to pass through the state during this time.  For today, rain and mountain snow showers will be possible in western portions of the state.  Elsewhere, expect increasing clouds, gusty to windy conditions, and mainly dry weather conditions.  Winds across southwestern, central, and northeastern Wyoming could gusts between 35 and 50 mph, with occasional higher gusting possible at times.  Temperatures will also be unseasonably mild throughout the state, with highs in the 50’s and 60’s.  By tonight, rain will mix with and quickly turn to snow across lower elevations of western Wyoming.  Rain will also develop and quickly turn to snow across central Wyoming tonight.  Roads will become slick and icy across lower elevations, including on I-80 (Utah state line to Arlington), as well as over the mountains and mountain passes.  Scattered snow showers are expected throughout the day on Wednesday across western and central Wyoming, which will create periods of reduced visibility and slick/icy roadways.  Snow will then develop across much of eastern Wyoming by Wednesday evening and night.  The main concern will be southeastern Wyoming, where light to moderate accumulations are expected into Thursday morning.  Roads will also likely be slick and icy, with lingering slick spots possible elsewhere.  We will also see cloudy to mostly cloudy skies and noticeably colder temperatures statewide on Wednesday.  There will be a smaller chance for light snow on Thursday and Friday, but watch out for some slick and icy spots.  Temperatures will also remain colder than normal during this time.
