A low pressure system slinking its way across the northern midwest of the United States has set a new record as its central pressure is now the lowest on record for a U.S. non-tropical land-based system with a barometeric reading of 956.31 mb 954.95 mb in Minnesota. To put this into some perspective, a Category 3 hurricane usually has a atmospheric pressure of 964-945 mb, but unlike a hurricane the pressure system does not have a large, warm body of water to feed itself with so it isn't quite the same.
The center of the storm is off to the northwest of me, and our local barometer is reading 979.68 mb. The wind is howling, rain is coming down in sheets, and I need to walk the dog still.
