Was 74° yesterday, clear and near calm, on my mountainside SE of Tucson.
We can't even BUY winter down here... I miss it, like that badly infected tooth I had yanked out once. (Once per tooth is about the limit, no?)
Seriously, though, (i.e., you have warning the BS is on the way) it does get cold down here occasionally, but doesn't stay all-winter type cold. I've seen temps in the 0°-15° range. But deserts don't hold heat, so a lot of that is early morning radiation cooling, before the sun is high enough to warm anything. We can see early mornings in the 30's and afternoons in the 70's. We wear thermometers out.
We even have snow in the deserts, now and then. One year I couldn't get to Tucson for the SW Regionals. I-10 was snowbound, and all 3 of Arizona's snowplows were busy up around Flagstaff...
Final insult? Been there; done that; moved to Arizona...
Feel for you guys, sincerely. It ain't fun, especially for the deep south folks whose blood has thinned to adapt to the warmer climate.
