I grew up in Dallas, and one year in the early 80’s, the temperature did not get above freezing for 3 weeks. White Rock Lake was frozen and people were ice skating on it.
My mom still lives in Dallas, and I don’t think she’s been In a winter as bad as that one.
A couple of years ago they had a bad ice storm and my parents were without electricity for almost a week. We never personally lost electricity when I was growing up. I think that was the worst winter for my parents.
