A large synoptic scale storm system that originated across Colorado, moved northeast across the Plains and Upper Midwest from late Thursday November 17th, through early Saturday, November 19th. The bulk of the heavy snowfall occurred Friday morning through Friday afternoon, when locally 6 to 12 inches of snow fell across west central and into central Minnesota. In addition to the heavy snowfall, strong winds developed, creating blizzard conditions in west central Minnesota by Friday morning as the system intensified.
Initially, a band of mainly light precipitation spread northward into western Minnesota the early morning of Friday, November 18th. A couple of inches of snow fell along the Minnesota, South Dakota border, northeast to near Alexandria and Wadena before 6 am LST. In the warm sector, rain and some sleet occurred along with thunderstorms during the morning in southern Minnesota. Once the surface low moved from north central Iowa, northeast to west central Wisconsin, any mixture of sleet, rain or snow in western Minnesota, quickly changed over to all snow and became heavy with snowfall rates of 1 to 2 inches per hour.
The most intense time when both heavy snow and high winds occurred was between 6 am LST and 3 pm LST. This is when the pressure gradient strengthened and caused widespread wind speeds of 30 to 40 mph across southwest, and west central Minnesota. Highest gusts of 50 to 55 mph were recorded during the morning, and early afternoon.
Although the snow was wet and heavy, the combination of strong winds, and intense snowfall rates, produced blizzard conditions. The most snow fell in an area from Villard, Sauk Centre, north-northeast to Long Prairie, Little Falls and Camp Ripley. The heaviest snowfall in the state occurred in north central Minnesota and the arrowhead of Minnesota where up to two feet of snow fell. Once the snow tapered off in western Minnesota, surface visibility increased rapidly, gusty winds kept the area roadways snow covered, and no travel was recommended by the Minnesota Department of Transportation as numerous accidents occurred.
