One of the amazing aspects of the Mega Storm was that it was what we call a "Gulf Storm." Gulf Storms form as the center of low pressure tracks all the way south to near the Gulf of Mexico, instead of say a Colorado Low, Panhandle Hook or Alberta Clipper.
Gulf Storms are rare for Minnesota and they produce the wettest heaviest snows because they suck up deep moisture form the Gulf of Mexico and charge almost straight north toward Minnesota and Wisconsin, wringing out heavy wet snow as moisture slams into the cold air dome over Minnesota.
Everyone has a weather story, and I've found that the Halloween Mega Storm is one of those events when everyone remembers where they were.
So where were you in '91? Please share!
