Winter Storm — Gillette, Wyoming

2001-02-06 to 2001-02-07 · Gillette, Wyoming

Wider weather episode

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, and spread into Northeastern Wyoming. By early the morning of the 7th, heavy snow had fallen over nearly all of northeastern Wyoming. Campbell, Crook, and Weston counties were covered with 8 to 10 inches. The heaviest snow fell in the Bear Lodge Mountains and Wyoming Black Hills, where 9 to 18 inches of snowfall were widely reported.
