Winter Storm Summary - Dec 15/16, 2015

A strong Colorado low pressure system moved northeast during the daytime hours on Tuesday with a band of intense snowfall working into the southern Red River Valley before midnight. This intense snowfall was quickly cutoff in the central and southern valley as a dry layer aloft known as the "dry slot" lifted into the area in the early morning hours on Wednesday. This initial intense band of snow produced a quick 3 to 4 inches of snowfall in a 2 to 3 hour period. This band rotated around the low and stalled over part of eastern ND, allowing heavy snow to fall for a long period of time from near Pembina, ND to Cooperstown, ND. This is evident on the radar imagery and in the snowfall map where locations under the prolonged banding snowfall received up to 13 inches of snow.
