Temperatures will be colder and closer to average throughout the state of Wyoming today due to a cold front that crossed the region yesterday.  Daytime highs will be in the 30's and 40's.  Windy conditions are also expected by this afternoon and evening, mainly throughout central and southern portions of the state.  Parts of I-25 (Colorado state line to Wheatland), I-80 (Cheyenne to Arlington), and US-85 (Colorado state line to LaGrange) could see gusts between 50 and 60 mph.  Conditions remain mainly dry during the day statewide, with the exception of far northwestern Wyoming.  A cold front and weather system will then approach northern and central Wyoming tonight, which will create increasing clouds and a chance for light snow.  Roads could also become slick in icy in places, especially across I-90.  Meanwhile, conditions stay mainly dry throughout southern Wyoming.  This cold front will continue to dig south for the rest of the day on Tuesday.  There will only be a chance for snow in northern and central Wyoming on Tuesday morning, while the rest of the state stays mainly dry.  Strong and gusty winds are also expected again throughout the state.  Temperatures will be cold and close to average in northern and central Wyoming, while unseasonably mild temperatures will be found in southern Wyoming.
