Heavy Snow over Southern and Central Minnesota:
March 12-13, 2006

A powerful spring storm moved from eastern Kansas to southern Wisconsin on March 12th and 13th. This storm brought numerous tornado reports from Kansas to Illinois. This storm also dumped a swath of heavy snow across central and southern Minnesota and into western Wisconsin. At the Twin Cities International Airport 10.7 inches fell. This was the largest snow amount in a Twin Cities snowstorm since February 1-2, 2004. In this storm 11 inches fell over three days.

The snow began with a mixture of sleet and a rumble of thunder in the evening hours of March 12. About an inch of snow fell during the evening across the Twin Cities. There was a lull in the precipitation later in the evening. Then around 1am on March 13, snow moved back in around the Twin Cities and became heavy during the morning commute. At 8am at the Twin Cities International Airport visibilities were down to an eighth of a mile in heavy snow. The snow gradually tapered off during the early afternoon on the 13th.

One interesting aspect about this storm was the high water content of the snow. In St. Paul, where most of the precipitation fell as snow, 7.8 inches of snow melted down to .84 inches of water. Average precipitation for the entire month of March in the Twin Cities is 1.86 inches. In places where some rain mixed with snow precipitation amounts were even higher. Winnebago saw 1.23 inches of precipitation and Zumbrota saw 1.15 inches.
