Believe it or not, it does. It's usually in January or February. You're down around DFW aren't you? That's about even with Montgomery. I'm up in the NW corner of Alabama, about even with OKC. It's hard to believe that that small of a distance can make that big a difference in the temperature. Those really cold temps usually only last a couple of weeks and the sun usually warms everything up to above freezing during the day even then, but not always. The coldest I ever remember it being here was 5 below zero and that was at least 20 years ago. I was in college, and Dang, that's cold, I don't care where you're from. I don't see how people LIVE in Canada! Too cold for my wimpy-ass Southern blood! ;o)
Yes, I'm near DFW and I also have wimpy ass southern blood. :)
