May 1-3, 2013 Record Heavy Snow

Meteorological Overview Snowfall Graphics Photos Snow Totals

Overview

A slow moving, potent spring storm brought unwelcomed, heavy snow to parts of the region from late Wednesday night (May 1st) through Thursday, May 2. The snow lingered into Friday the 3rd. Prior to that, the storm's surface low and cold front sparked a few showers and thunderstorms on Monday and Tuesday (April 30-May 1), with a few severe storms late Monday night into early Tuesday morning.

Unseasonably cold air flowed in behind the front, with 70s to low 80 highs ahead of it and 40s behind it. Cold air continued to invade from the west and north Wednesday night while a band of precipitation set up from northwest Wisconsin, across southeast Minnesota, and southwest through central Iowa. The band intensified late Wednesday night, and with ample cold air, what fell was mostly snow - and very heavy at times. 1 to 2 inch per hour snowfall rates were common overnight Wednesday. Despite the warm grounds, roadways became snow covered, resulting in slick and dangerous travel Thursday morning.  The bulk of the snow fell on Thursday.

Daily snowfall records were set at many locations. In fact, the one-day totals also set monthly records!
