The early morning twister touched down around 1:15 a.m. near Concord, the agency tweeted after inspecting the scene. Meteorologists later determined max winds reached 105 mph within a 12.6 mile path from just south of Watertown to Dousman.

Based on its preliminary survey of the damage, the NWS classified the tornado as an EF-1.

Later, NWS meteorologists also confirmed a second tornado which traveled 2.2 miles in Waukesha Co. near Dousman. Based on damage reports, that one was given a preliminary EF-1 rating with max winds reaching 100 mph.

A third EF-0 tornado was confirmed SW of Watertown, touching down shortly after 1 a.m. and leaving damage along Hilltop Rd., just north of Highway A. Max winds reached 80 mph with meteorologists classifying it as an EF-0 tornado.

A fourth EF-1 tornado was confirmed near Wales and traveled to just SW of Waukesha. The brief twister was on the ground for 5 minutes - spinning up to EF-1 strength with max winds of 95 mph.

Another survey is expected Friday between Verona and Middleton as well as near Ripon and Brandon.

The severe weather that swept through Wisconsin, cutting a north to south path, started late Wednesday night and did not leave the state until early the next morning. In that time, the storms caused significant damage to buildings, knocked down trees and power lines, and caused multiple road closures.

Tens of thousands of people were left without power at various points in the night.

Late Thursday morning, Gov. Tony Evers issued a State of Emergency order that covered all of Wisconsin. The declaration directed state agencies to help assist with the recovery efforts and freed the Wisconsin National Guard to activate and work with civilian agencies, if necessary.
