Temperatures will be cooler and slightly below normal today across much of the Cowboy state.  Expect highs generally in the 30's to low 40's by later this afternoon.  Scattered snow will gradually come to an end by late morning and early afternoon across southeast Wyoming, leaving slick and wet road conditions in spots.  Scattered snow may continue a bit longer across the Big Horn mountains and over the northern-most mountain ranges.

As warmer temperatures move in for Tuesday, areas of fog will likely set up across the state's valleys and basins, and parts of southern and southeast Wyoming into Tuesday morning.  Some of this fog may cause some icing and possible slick spots on roads.  There will be a chance for very light snow showers with fog across southeast Wyoming's higher elevations, especially along parts of I-80 between Cheyenne and Arlington.  Otherwise, developing sunshine is expected Tuesday, with warmer temperatures and drier conditions.  The next storm system to affect Wyoming arrives Wednesday afternoon through Thursday with rain and snow.
