Early season snowfall in Hermantown, MN on October 26-27, 2010!

This is the snow received in Hermantown, Minnesota from what is being called "The North American Extratropical Cyclone of October 26-27, 2010." This is the storm that set a new record low pressure for the state of Minnesota when at 5:13 PM CDT on October 26, 2010, the barometer fell to 28.21 inches of mercury at Bigfork, Minnesota. This storm started as rain on the 26th in Hermantown, and temperatures were in the low 50s in the morning. Over 2 inches of rain fell before the temperature dropped to around 37 in the late afternoon and precipitation mixed with and then changed to snow. Overnight, near blizzard conditions occurred with wind gusts over 50 MPH recorded. By morning, around 8 inches of snow had fallen. This was a very strong storm indeed, and it's especially interesting because the heaviest snow fell to the south and southeast of the low pressure center, rather than to the west and northwest, which is much more common. While it was snowing in Hermantown, the temperature was still in the 40s in International Falls. The storm was so strong that it brought the warm air around to the north and cold air around to the south. It certainly was a rare event.

Stormtracker05 is correct, generally a large powerful low pressure system, formerly a tropical storm before making landfall however it got absorbed by a very strong cold front the "extra-tropical low within 4 days re-arranged the frontal system causing to occlude in a cold pool both at ground level and aloft the result was a wide variaty of weather some snow was being reported 85 miles SSW of low pressure center, while 60 miles to your ESE was getting thunderstorms with hail.

@stormtracker05 Thanks, I never knew it had a term! This was one wicked storm, to say the least. You seem to know quite a lot about weather. Are you going to college for it or did you learn on your own?
