(WQOW) -- The National Weather Service has upgraded the tornado that tore through northern Wisconsin from an EF-2 to an EF-3.

The NWS says new evidence shows that wind speeds reached 140 miles per hour. Drone footage and survey results show that tornado tracked along a damage path 83 miles in length -- making it the longest tornado in Wisconsin recorded history.
