Minnesota Normal Annual Snowfall: 1981-2010

A climate normal is defined as the average of a variable over a continuous three-decade period. At the end of each decade, a new 30-year average is calculated. The statistic is a measure of the central tendency of the variable. Minnesota's highly variable climate leads to large year-to-year swings above and below this benchmark value.

The normal snowfall map incorporates data from the MNDNR Snow Rules project. The project gathered high spatial density snowfall data from 2002 through 2011 in three northeastern Minnesota counties (St. Louis, Lake, and Cook). Despite the nine-year time-span being less than the 30-year normal period, these data were included to offer an picture of the unique snowfall patterns found along Minnesota's North Shore.


For a regional view of normal annual snowfall totals, the Midwestern Regional Climate Center offers a normal annual snowfall map for the Midwest.

Normal snowfall statistics for many cities in the United States can be found here. Normal snowfall data for the Twin Cities, including thresholds, are found on page two of Twin Cities Climate Normals.
