The coldest temperatures I ever experienced was in the winter of 1994. I know that people up north and the Midwest have been through much worse, but being from the East coast, I was not used to it. I was living in Louisville in ‘94 and we had air temps around between 0 to - 10 for about a week. That was after we had a surprise 13” snow storm that ended up shutting down the city for close to a week. No one was prepared for it because it was only supposed to be 1 inch! The highways were closed around Louisville and they literally sent in the National Guard to plow out the city. It was like lake effect snow along the Ohio River. It was so cold in Louisville that we couldn’t even enjoy the snow. I don’t look forward to that kind of cold again. My parents were in MD, so I know that the DC area was hit with a terrible ice storm a that same week.
