Assessing the damage: Storms that passed through NE Wisconsin spawned 4 tornadoes

GREEN BAY -- The National Weather Service in Green Bay indicates a storm that passed through northeast Wisconsin on Monday, July 6th spawned four tornadoes. That's the preliminary word from weather teams on the ground in the region.


The NWS says the first tornado developed just ahead of the main line of showers over northern Waupaca County. Officials say this storm generated a brief EF1 tornado about 3 miles west of Marion in extreme northern Waupaca County.

As this cell continued to move northeast into Shawano County, it produced another very weak tornado (EF0) that briefly touched down near Pella in central Shawano County around 5 p.m.  The dashed circle in the image below denotes a new circulation associated with a different cell that was developing to the southeast of the Pella (just north of Embarrass).

This new cell north of Embarrass continued to organize and strengthen and eventually produced an EF1 Tornado near Gillett in western Oconto County around 555 pm CDT (see image below) as well as another brief EF0 just to the east.
