Weather Summary for northeast Minnesota and northwest Wisconsin
Date:  October 10, 2016

Couldn't ask for a nicer fall day around here.  Highs today warmed into the upper 60s to lower 70s under a partly cloudy to mostly sunny sky.  Temperatures today were a good 10-20 degrees above average for the 10th of October.  It was a windy day though but this is quite typical for this time of year, winds were out of the south or southwest at 10 to 20 mph with gusts to around 30 mph.  Surface map at 5 PM had a cold front stretching from north of Lake Superior to northwest Minnesota to east central South Dakota.  Believe it or not a few thunderstorms have developed this afternoon north of Minnesota across southern Ontario Province.  The atmosphere over parts of the Northland has become a little unstable this afternoon with late afternoon elevated CAPE sitting at around 500 j/kg.
