Minnesota is know for it's changes in weather..i've come out of a movie in the winter to find the weather was much colder.
it was 20 below last week--35 today and down to 8 or so below
tomorrow..in the summer it's the thunderstorms that come up fast.
with the modern weather forecasts what would have been a fast change in the weather--morning to afternoon--is no surprise but
heavy winds over our lakes can come on very quick.out of a nice summer day a calm lake will go to whitecaps in minutes.
Lake Superior is a killer when it come to that.even the cottage country lakes will "stand on end" and drive fisherman to shore.
