I GUESS "LAND HURRICANE" IS ONE WAY TO PUT IT. In case you haven't heard it was officially the strongest non-tropical low we've seen in the Continental U.S. -  record low of 955.2 at Big Fork, MN. To put things in perspective - the storm was comparable to a category 3 hurricane. This storm has definitely surpassed some of the strongest historical storms in the upper midwest. 

Pictures from Grand Marais, North Shore Lake Superior - 26 foot waves came ashore with sustained wind gusts in the 60 mph range.
