Casper will be mostly dry today and this evening but mountain snows will be on the increase.  Brisk winds, colder temperatures and snow showers for Casper and most of the state tonight and early Tuesday.  Snow will be heaviest across the mountains and then the northern, central and east-central plains.  The Casper area will likely see two to five inches of snow with more on Casper mountain. 

Southeastern Wyoming will see the lightest accumulations.  Expect travel and livestock conditions though to be impacted nearly statewide on Tuesday.
