Southward pushing cold air near the surface interacted with a post-frontal wave in southwest flow aloft to produce a prolonged period of light snowfall, which began as a period of light freezing rain and freezing drizzle across far southwest Minnesota during the afternoon and early evening of February 21. In addition to snowfall which accumulated from as much as 1 to 2 inches, strong northerly winds produced dangerous wind chills from 25 below to 35 below zero from later on February 21 through the afternoon of February 22.
