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 start in northeastern Wyoming toward midday, and then shift into the Black Hills and western South Dakota late this afternoon and evening. 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.

Total snow accumulations of 1 to 4 inches are expected on the Weston County plains, with snow totals of 3 to 7 inches expected for the Wyoming Black Hills. Heavier snow is expected in the higher terrain of the Black Hills. Winds gusting as high as 40 mph will be likely with this storm.

A Winter Storm Warning remains in effect from 3 PM Monday afternoon until 6 AM Tuesday for Weston County Wyoming, including the cities of Newcastle and Upton, and a winter storm warning is also in effect for the Wyoming Black Hills including Four Corners.

Those living in the forecast area can expect high temperatures 10-20 degrees colder than average during the storm time frame, with prolonged cold temperatures expected to follow in the coming days.

Plan on slippery road conditions, with areas of blowing snow, with reduced visibility. These hazardous conditions could impact evening driving.

The latest road conditions can be obtained by calling 5-1-1.
