Heavy snow is in the forecast. While most of us enjoyed a warm Sunday, a large winter weather system is engulfing the western United States. Snow showers are currently over the west Wyoming border spilling from north Utah and east Idaho. Monday morning will bring snow north and south of the Wind River Range. It won’t be until Monday evening when a large influx of moisture from northern Colorado and the Central Plains injects additional moisture along the cold front that will have passed most of Wyoming. The moisture from the plains will overrun the frontal boundary and produce large amounts of snow on the west side of the boundary into eastern Wyoming, northwest Nebraska, and southwest South Dakota.
