The 35th anniversary of one of the worst thunderstorm wind events to hit northern Wisconsin is July 4th. The landscape in a long strip from near Lake Mille Lacs in Minnesota to east of Rhinelander in Wisconsin was devastated by straight-line winds to 100 mph or stronger.
The anemometers at the airports near Phillips and Rhinelander registered 100 mph winds before they blew away. The storm cluster struck that area from around 1 p.m. to 3 p.m. as it rapidly raced eastward.
It flattened huge amounts of forest, destroyed or damaged many buildings and killed one person, and injured 35 others. This storm was extensively studied by severe weather and tornado researcher, Dr. Ted Fujita. He of course developed the famous Fujita Scale to measure tornado intensity based on the damage caused.
