The entire state of Wyoming will be in between weather systems for the rest of today.  Expect partly to mostly sunny skies, light to breezy winds, and mainly dry weather conditions statewide.  Temperatures will also become warmer and above normal.  Daytime highs will stay in the 60's and 70's, with 50's possible over higher elevations and the mountains.  A cool front and weather system will then quickly approach the region late tonight and continue to move across the state on Thursday.  Clouds will thicken statewide tonight.  Rain showers and a few thunderstorms will also develop by early Thursday morning across far northern Wyoming.  Areas of patchy fog could also be possible along I-90 and could lower visibility at times.  Rain showers will then be possible for northern, central, and eastern Wyoming for the rest of the day.  Watch out for wet roads with some areas of fog and reduced visibility, especially in the evening and early overnight hours.  Temperatures become cooler and closer to average for these locations, with highs in the 50's and 60's.  Meanwhile, there will be only a small chance for showers and thunderstorms in the far southwest corner.  Temperatures will also remain unseasonably mild, with highs in the 60's and 70's.  Higher pressure builds over the region on Friday, which will keep skies mostly sunny and conditions mainly dry.  Temperatures will also become warmer than normal for the end of the work week.
