High pressure will start to build in from the west.  It will dominate the weather across the Cowboy State for the next several days.  This means that mostly sunny to partly cloudy skies, mainly dry conditions (there will be a few snow showers in the northwest) and warmer temperatures are on the way over the next several days.  Temperatures will top off mainly in the 30s and 40s today.  By Wednesday and Thursday, some portions of southeast Wyoming could see highs in the 60s.
