Colder Temperatures With Rain & Snow Spreading East Across Wyoming Today Into Thursday Morning
A trough of low pressure will be settled over the state of Wyoming today, Thursday, and Friday. This will cause a series of cold front and weather disturbances (one today and another on Friday) to slide across the region. For today, light snow or a rain/snow mix will be possible throughout western and central Wyoming. Watch out for lowered visibility and slick/icy roads. Rain will then develop across eastern Wyoming later today and will then mix with and quickly turn to snow tonight. The main concern overnight will be across southeastern Wyoming, where cold temperatures and light to moderate snowfall is expected. Lower elevations will generally see 1-3″, but up to 6″ could be possible near Wheatland, Bordeaux, and Chugwater. The Summit over I-80 will also see up to 8″ of snow by early Thursday morning. Slick and icy roads will be likely, with snowpacked roads expected over the Summit. For the rest of the state, light snow showers will continue overnight, with little to no accumulations expected. However, it will be enough to create slick and icy spots on roadways. Snow showers will gradually taper off throughout the state during the morning hours on Thursday. Slick, icy, and some snowpacked (over the Summit) roads will also linger through mid-day. Expect partly to mostly cloudy skies and improving weather conditions for the rest of Thursday. By early Friday morning, light snow will redevelop across northern and western Wyoming. Light snow will then be possible throughout the state during the afternoon and evening hours. Temperatures will be cooler and closer to average statewide today, with highs in the 30’s and 40’s. Lower 50’s will be possible in the far eastern plains. Significantly colder and well below average temperatures will then arrive on Thursday and Friday, with daytime highs in the 30’s to lower 40’s.
