Snow and Cold: May 7-9, 2010

More snow fell on May 7-8th in Minnesota than March and April 2010 combined. The heaviest snow reported at an official national Weather Service Station was 4.5 inches at Duluth, this was the 3rd largest snowfall reported in May for Duluth. There were some unofficial reports of greater amounts in the higher terrain of the Iron Range. A total of 7 inches was reported near Hibbing, and 8 inches near Grand Rapids. The weather system responsible for the snow was a developing low pressure area that moved from Missouri on the morning of May 7th to the eastern Great Lakes by May 8th. There was just enough cold air mixed in the system to allow the precipitation to reach the ground as snow. It was snowing by 8am on the 7th in Duluth and slowly the rain changed over to snow farther south. Just a trace of snow was observed at St. Cloud and the Twin Cities International Airport.

After the snow cleared, May 8th was a blustery day with some scattered rain and snow showers in the morning, then as the skies cleared in the evening, the temperature plummeted. People awoke to a frosty start on the morning of May 9th, with many locals in southern and central Minnesota bottoming out in the upper 20's to lower 30's. The coldest temperature found in Minnesota was 17 degrees at Embarrass in St. Louis County.
