A weak ridge of high pressure will build over much of the state of Wyoming today, which will keep skies mostly sunny and conditions mainly dry.  However, flurries or light snow showers will be possible in the western and southern mountains as well as lower elevations of southwestern Wyoming, including I-80 (Utah state to Arlington).  Skies will stay mostly cloudy in these areas.  Temperatures will be cold, but close to average statewide with daytime highs in the 20's and 30's.  A series of fast-moving weather systems will pass through the area on Wednesday and Thursday.  This will continue to create flurries or light snow shower activity in the western and southern mountains and lower elevations of southwestern portions of the state.  No major travel concerns are expected during this time.  Temperatures will also remain close to average.  Higher pressure returns to the area for the end of the work week, which brings more settled weather to the entire state.
