A line of thunderstorms crossed southern Wisconsin during the overnight hours of Monday, July 13th. The storms initially developed over eastern North Dakota Sunday afternoon. They produced large hail, damaging winds and a few tornadoes across portions of central Minnesota. The storms evolved into a line and tracked southeast into western Wisconsin late Sunday night and crossed south central and southeast Wisconsin early Monday morning. There was a lot of straight line wind damage in southern Wisconsin.

Radar loop across southern Wisconsin starting around 1 am and ending just before 7 am

Nearly all of southern Wisconsin experienced sporadic wind damage. There were many reports of downed trees, some which fell on houses, cabins and power lines. There was a report of one-inch hail in Beaver Dam. The radar identified rotation in one segment of the bowing line of storms over the town of Columbus and then the rotation weakened as it tracked through southern Dodge County. The NWS Warning Meteorologist issued a tornado warning after seeing the rotation. The NWS Damage Survey Team surveyed Columbus this morning and determined that the damage was caused by straight-lined winds in that location. The survey team also determined that damage in Dodge County was due to straight line winds.
