It's been an active summer across the Northland with numerous severe weather events during the past couple of weeks. Damaging winds and hail have been common with the Brainerd Lakes vicinity being one of the harder hit areas so far this summer.  There's also been a few tornadoes especially in north central portions of Minnesota.  I guess you could call the flood from July 11th Mother Nature's knock out punch but since it's only early July, I'm pretty sure were going to be dealing with a few more severe weather/flood events through the rest of the summer.
