It was really weird a couple of weeks ago when we had that freak storm system roll through the Great Lakes. The day started out nice and warm, and as the day went on the temperature fell fast and the winds reach near hurricane strength. Records were set for the lowest land-based barometric pressure reading (weathermen said it was the equivalent of what you'd see with a Cat 3 hurricane). They said that there'd only been a handful of such storms recorded on the Great Lakes... and one of them was November 10th, 1975.
