Significant Winter Storm Moving Into the Area Monday
NEWCASTLE, WY. – A strong upper low and associated upper trough will bring snow and blowing snow into the area beginning Monday and continuing through Tuesday morning.

The snow will persist through tonight, but end by Tuesday morning.
The highest snow accumulations are expected across the northern Black Hills, with lighter snowfall accumulation expected across the rest of the area. Gusty northwesterly winds are expected to create difficult travel conditions due to blowing and drifting snow.
