Heavy Snow: February 20-21, 2011

The February 20-21, 2011 snowstorm is the largest February snowstorm on record for the Twin Cities since 1891.

February is typically not known for large snowstorms. However, this February is the exception to the rule with the February 20-21 storm setting the largest snowfall record for February for the Twin Cities International Airport. The storm total was 13.8 inches, easily breaking the old record of 11.2 inches that was set with the storm of February 1-2, 2004

This storm began with a low pressure area that moved eastward from Nebraska across Iowa. Light to moderate snow spread northward across southern Minnesota on Sunday morning the 20th, with the snow beginning in the late morning hours across the Twin Cities. Light snow began to fall at the Twin Cities International Airport at around 10am. The snow became heavy by late afternoon, with visibilities a 1/4 mile or less at the Twin Cities International airport from 3 to 6pm on the 20th. Flashes of lightning were observed with the heavier snow bands across the Twin Cities. Some drier air worked its way northward and tapered off the snow over the Twin Cities after midnight. Freezing drizzle then coated the top of the snow pack, forming a thin veneer of ice. Light snow began again over the Twin Cities during the morning of Monday, February 21 and visibilities dropped below a mile with snow in the afternoon as part of the departing storm system lingered over central and southern Minnesota.

Many places in central and southern Minnesota north of Interstate 90 saw from 8 to 12 inches, with the highest totals in an east to west line from west central Minnesota through the Twin Cities and then into west central Wisconsin. Madison in west central Minnesota in Lac Qui Parle County saw the most snow with 20 inches. Portions of the southwest Twin City Metro area also saw up to 19 inches.

This is the second snowstorm to be the record largest snowstorm for the month for the Twin Cities during the 2011 winter season. The December 10-11, 2010 storm was the largest snowfall on record for December and now the February 20-21 is the largest snowfall on record for February.
