Winter Storm Brings Impressive Snow Totals Impressive snow totals really stacked up over southeast Wisconsin! The snow came from an area of low pressure passing to our south, along with some Lake Effect Snow. Below are 3 analyzed surface weather maps from early morning on Monday through Monday evening.
While we don't often see heavy Lake Effect Snow in southern Wisconsin, this is common in other areas (think Buffalo, NY) during the winter. Snow totals averaged 10 to 15 inches near the Lake, with a few places in Racine county picking up over 20 inches! Amounts tapered off to around 3-4 inches from around Madison west. Milwaukee broke its daily maximum snowfall record on 3/13 with 8.7 inches. The previous record was 6.7 inches set in 1972. The storm total snow in Milwaukee (for all three days), was an impressive 11.2 inches. Places which didn't see the Lake Effect Snow, such as Madison, had much lower totals. In fact, the snow total in Madison was only 4.2 inches (a full 7 inches less than in Milwaukee--this really shows you what Lake Effect snow can do!). Here's a graphic showing the snow totals across southern Wisconsin:
Radar Loops These radar loops span the time from 7 pm Sunday until 3 pm Tuesday (click to enlarge). Light snow overspread southern Wisconsin Sunday evening and tapered off Monday morning. Winds were out of the east. Extra moisture off of the lake enhanced the snowfall totals in many lakeshore areas. Sheboygan, Milwaukee, Racine, and Kenosha had all reported 6 to 8 inches of snow by 7 am Monday. Inland areas had 3 to 5 inches by 7 am. You can see that a few lake-enhanced snow bands started converging just north of Milwaukee Monday afternoon. This caused snow to pile up quickly in a small area. Mequon and Newberg picked up 10 to 15 inches by late Monday afternoon. The lake effect snow band took on more of a north-south orientation Monday night. This band brushed southeast Wisconsin late Monday night into Tuesday morning. Additional "waves" of snow in the lake effect band kept affecting the Wind Point area of Racine County. Snowfall totals ended up in the 15 to 23 inch range there!
