Winter Storm in Meade Co. Plains, South Dakota

A digging upper level trough over the Southwestern United States supported an overrunning/warm front pattern to develop over the northern plains and along the front range of the central and northern Rockies. Strong low level, moisture laden warm air moved over cold air already in place over the northern plains. Snowfall developed quickly over western South Dakota during the afternoon and evening of Feb. 6. By early the morning of the 7th, heavy snow had fallen over much of western South Dakota. Nearly every county in western South Dakota reported 6 to 9 inches. The heaviest snow fell in a wide swath from the northern and central Black Hills, across Meade, and into Ziebach counties. In this area of heaviest snow, most reported snowfall was 8 to 12 inches. A significant area in the Central and Northern Black Hills recieved more than 18 inches.
