Snow is expected to begin falling over western and central Wyoming beginning today, followed by windy conditions that could make travel difficult.

The National Weather Service office in Riverton is forecasting 3 to 4 inches of snow in Casper, 4 to 6 inches in Jackson and Sheridan and even higher amounts in Yellowstone. The agency has issued a winter weather advisory for much of the state and a winter storm warning for the far west.

The snow should end Monday, but high winds could result in blowing snow and drifting, according to the National Weather Service. 

After a weekend of mild temperatures, thermometers are expected to plunge overnight Sunday to 22 degrees in Casper. Windy conditions will make temperatures feel even colder, the Weather Service warned.
