An upper-level weather system will remain settled over the Rockies and Plains today and will then slowly move out of the region on Wednesday.  For today, expect partly to mostly cloudy skies, breezy to strong winds, and cooler than normal temperatures.  High temperatures will remain in the 40's and 50's.  Scattered rain showers and thunderstorms will also be found throughout the state.  By later tonight, rain could mix with and turn to snow across the higher elevations of I-80 and northeastern portions of the state.  Roads will stay mainly wet, but we cannot rule out a few slick spots.  We will then see partly to mostly sunny skies and a smaller chance for showers and thunderstorms on Wednesday.  Temperatures, however, will remain cool and below normal.  Higher pressure will then build over the region on Thursday and Friday, which will make temperatures warmer and closer to average.  However, lingering low-level moisture and daytime heating will continue to create minimal chances for showers and thunderstorms.
