Don’t rush a good snow storm

The latest computer model guidance, based on upper air observations taken at 6am, is holding firm on the potential for heavy snow from South Dakota through the southern half of MInnesota into Wisconsin. Snow will likely be mixed with sleet for a time early Sunday in far southern Minnesota.

Here's one of the computer model's projections for the position of the center of the surface low at 6PM on Sunday. Old school synoptic meteorology tells me this is in a great path to produce heavy snow from Marshall up to St. Cloud to the Twin Cities. Wind barbs are in knots. Expect winds of 20 to 30 miles an hour to blow and drift snow Sunday and Sunday evening.

There is no need to start altering snowfall predictions. The heaviest snow will likely occur from 9AM until about 10PM Sunday. More than twelve hours of moderate to heavy snowfall will tally up to ten plus inches of snow in some locations.
