High pressure will build over the state of Wyoming today and will remained settled over the area through Wednesday.  Any areas of patchy fog, mainly along I-80 between Cheyenne and Laramie, will dissipate by mid to late morning.  Otherwise, expect sunny to mostly sunny, light to breezy winds, and mainly dry weather conditions during this time.  Temperatures will become warmer and closer to average today, with daytime highs in the 50's and 60's.  We will then see unseasonably mild temperatures (60's and 70's) by Wednesday.  A cool front and weather system will slide across the area on Thursday.  Expect increasing cloud cover, breezy to gusty winds, and a few isolated showers and thunderstorms.  Temperatures will become a few degrees cooler, but it will still be warmer than normal.
