Arctic high pressure will be settled over the state of Wyoming for the rest of today.  Expect partly to mostly sunny skies, breezy to gusty winds, and mainly dry weather conditions statewide.  Temperatures will be not as cold, but still colder than normal.  High temperatures will be in the teens and 20's.  A low pressure system will then approach the state tonight and will remain settled over the region on Tuesday and Wednesday.  This will cause a series of faster-moving weather systems and cold fronts to slide across the area.  We will see cloudy, overcast skies with a small chance for flurries or light snow during this time.  Only small, if any, new accumulations are expected, but it could be enough to create some slick and icy spots on roadways.  Temperatures will also become colder and well below average, with highs in the teens.  Wind chill values will be even colder and below zero.  Warmer and more settled weather is expected by the end of the week and start of the upcoming weekend.
