A ridge of high pressure will slowly move east today.  This will keep skies sunny to mostly sunny and conditions mainly dry across much of the state today.  Winds, however, will be strong and gusty across eastern Wyoming with gusts between 40 and 50 mph.  Temperatures across western Wyoming will stay very mild and above normal, while cool and seasonal temperatures can be expected for the rest of the state.  Daytime highs will be in the 50 and 60's.  A strong cold front and weather system will approach the state of Wyoming throughout the day on Saturday.  Expect increasing clouds and windy conditions for the entire state.  Temperatures will be unseasonably mild for the first half of the weekend with daytime highs in the 60's and 70's.  Rain and mountain snow showers will develop and stay mainly settled over far western portions of the state, but we cannot rule out an isolated rain shower for the rest of the state.  Significantly colder and below normal temperatures arrive on Sunday.  Rain showers will be possible across lower elevations early in the day, then quickly turn to light snow by the afternoon and evening.  Mountains and higher elevations like I-80's Summit between Laramie and Cheyenne could receive a few to several inches of snow on Sunday, which will reduce visibility and create slick, icy roads with some accumulating snow.  Light snow continues statewide Sunday night into Monday and will make many roads slick and icy.  Expect only small accumulations, if any, across lower elevations.
