Major Late Season Snowstorm
Duluth, MN

April 3 to 4, 2007

This storm was the third and last of big second-half season snowstorms for Winter 2006/2007 each of which totaled around a foot or more of accumulation. The other two events are described in separate storm entries. The other two storms occurred the last week of February and the first week of March. Prior to those three storms very little snow had fallen for the season.

Snow started to fall just before 3 AM on the 3rd and ended around 3:30 AM the 4th. Three periods of moderate to heavy snow fell from 5 AM to 9 AM, 1 PM to 4 PM, and 5:15 PM to 6:30 PM. After heavier snow ended at 6:30 PM, light snow showers or flurries continued beyond midnight, ending around sunrise the following morning.

Convergence at head of the lake appeared evident on radar, especially from late morning through the first half of the afternoon. An approaching trough from the west may have also contributed to the convergence.

Snow totals:
NWS Duluth, MN 12.2 inches
This observer 11.7 inches
