A trough of low pressure settled over the west coast will funnel a very limited supply of moisture and atmospheric instability into western Wyoming today and Wednesday.  This will create a small chance for flurries or light snow, mainly over the mountains and higher elevations.  Little to no new accumulations are expected, but watch out for a few isolated slick spots on roadways.  Meanwhile, higher pressure builds over the rest of the state.  Expect a mix of sun and clouds, breezy to gusty winds, and mainly dry weather conditions during this time.  Temperatures will also be warmer than normal statewide, with highs in the 30's and 40's.  The large low pressure system that has been settled over the west coast will then propagate east into the state of Wyoming late Wednesday night into Thursday.  This weather system will then remain settled over the region through Sunday.  Cloudy, overcast skies with light to scattered snowfall will be in the forecast statewide Thursday through Sunday.  The best chance for snow will be late Thursday night through early Saturday.  There will also be two cold fronts, one on Wednesday night/Thursday and another on Friday night/Saturday, that will bring very cold and well below average temperatures to the region.
