Local Snowfall, Precip and Wind Reports from the March 10-11, 2021 Winter/Spring Storm

A strong winter/spring storm hit the Northland Wednesday afternoon into Thursday morning bringing widespread heavy rain and snow to much of northeast Minnesota and northwest Wisconsin. Precipitation totals of 1 to nearly 3 inches were reported from east-central and northeast Minnesota into northwest Wisconsin, making this one of the biggest precipitation events we’ve seen in the Northland in months! Note: Duluth picked up 0.97″ of precipitation on March 10th, 2021, making it the greatest precipitation event in Duluth since November 9th, 2020 when 1.18″ of precipitation fell.

An estimated 9,000 Minnesota Power customers were without power Wednesday evening into early Thursday morning as widespread power outages occurred due to the combination of heavy wet snow and strong winds.

Note: About the only thing I was surprised about with last night’s storm was that we didn’t get any thundersnow in parts of northeast Minnesota, including in the Twin Ports, I really thought we would’ve had some of that given this storm’s dynamics, but it didn’t happen.

New record: 0.97″; old record was 0.56″ set 143 years ago in 1878.
