Two weather systems, one in Montana and another in Colorado, will pass by the state of Wyoming today.  This will keep skies partly to mostly cloudy statewide.  There will be a chance for snow showers in the western and southern mountains, while the rest of the state will remain mainly dry.  Winds could be breezy at times, but no significant gusting is expected.  Temperatures will also be chilly, but close to average with daytime highs in the 20's and 30's.  Another weather system will approach western portions of the state on Thursday, which will keep skies partly to mostly cloudy throughout the state.  However, the only  chance for snow will be in the western and southern mountains and the rest of Wyoming will see mainly settled weather conditions.
