Last night's season finale of Discovery Channel's Storm Chasers, season 4, entitled Judgement Day, featured an EF4 tornado that hit the small town of Wadena, Mn. June 17th was a historic day for Minnesota in that 48 separate tornadoes spun up in the state including a total of 3 EF4's. Skip Talbot shot some phenomenal footage of the EF4 monster that hit the area just west of Albert Lea, Mn. The structure of the clouds and the tornado in Skip's video is simply amazing.
I distinctly remember that day. I chased storms from Springfield, Mn. to Mankato, Mn. I saw no tornadoes, but I saw several storms with wall clouds and 4 rotating supercells train, one after another, over Mankato.
The Storm Chaser episode was entertaining, and it's too bad that they didn't stick around Minnesota for another week since June 25th was another very stormy day in Minnesota.
