The golden snow shovel award winner goes to Pleasant Lake, MN where 8.5" of snow fell through Sunday morning.

Snowfall So Far This Season
While the snowfall season isn't officially over just yet, here's how we stack up for the season thus far. Note that snowfall amounts are still running pretty close to if not slightly above average in the central part of the state, while many other locations around the region are running double digit deficits. Incredibly, Marquette, MI is running nearly 4ft. to 5ft below average this season!


Lake Superior Ice Coverage Update
Thanks to very cold weather during the first half of February, ice coverage across Lake Superior is running much higher than it did during the first 2 months of Meteorological Winter (December & January). As of February 28th, nearly 14% of Lake Superior was covered in ice. At this time last year, only 7% was covered, while nearly 85% was covered back in 2019. Looking at the graph of this winter's ice coverage vs the long term average, we actually spiked to above average levels during the middle part of the month during the Arctic outbreak, but we're running below average once again. The average ice coverage on Lake Superior as of March 1st is a little more than 40%.
