Overview

A strong low pressure system moved into the northern plains and stalled over the eastern Dakotas for a couple days, bringing a long duration of heavy snow and gusty winds to portions of northeastern WY and western SD. The heaviest snow fell over the upslope area of the northern Black Hills, where snowfall amounts of 2 to 3 feet were reported. Portions of northwestern and central SD received up to a foot of snow, while the downslope areas of southwestern SD and around the Rapid City area had little to no snow. Strong winds of at least 60 mph were reported on the plains just east of the Hills. On the afternoon the 30th snow and winds finally diminished across the area. The map below shows our snowfall reports. There are also a few pictures from the Lead area, along with a listing of some of the reports we received.
