A surge of warm air advection ahead of an approaching cold front brought widespread precipitation to southern Wisconsin. Precipitation started as rain and freezing rain in spots, but transitioned over to snow during the afternoon and evening hours. Many schools either cancelled ahead of time or had early dismissals early that afternoon. Snow accumulated quickly, impacting the evening commute. A strong cold front arrived that evening, bringing strong wind gusts of 30-40 mph. These winds caused blowing and drifting snow across much of southern Wisconsin as snow was winding down.
