I find it hard to believe that such a small amount of snow – in Wisconsin, yet! – could have broken any records.
Five inches of snow fell at the Dane County Regional Airport yesterday (Feb 9), eclipsing the 4.5-inch record snowfall that fell on Jan. 15.
Officially, a record 4.5 inches of snow was recorded at the Dane County Regional Airport on January 15, 2018.
The previous record snowfall for Jan. 15 in Madison had been the 3.8 inches that fell in 1943.
