A cold front and weather system will push through the state of Wyoming early today.  Scattered rain showers will be possible statewide across lower elevations, but the best chance will be in northern and southeastern Wyoming.  Rain showers could become heavy at times, especially in southeastern parts of the state in the afternoon and evening.  Light to moderate snowfall is also expected today in the northwest, northern, and southeastern mountains and higher elevations.  Temperatures will be cooler and well below average today.  Expect daytime highs in the 40's and 50's.  We will see rain showers continue tonight across southern Wyoming.  Expect rain showers to mix with and turn to snow tonight over I-80's Summit between Laramie and Cheyenne, which will create slightly reduced visibility as well as slick and icy spots.  Overnight lows will drop into the 30's and lower 40's.  Another fast-moving weather system will cross the region on Thursday.  Temperatures will continue to stay cool and below normal.  Rain will mix with and turn to snow across eastern Wyoming in the evening and overnight hours.  Expect mainly small accumulations, but reduced visibility and slick spots will be possible at times.
