Lyn, our lowest temps last year were way below zero! It get cold here for sure I know we got down to -10 for sure and maybe lower than that.
I will check into Oklahoma, I surely can't go wrong with one made for our climate.
Andi, we are mostly dry and hot, hot in the summers. Normally low humidity except spring when we could have trouble cool temps and too much moisture. The wind is crazy, sometimes blowing 30-40 mph for days on end so yes to windy!
I appreciate all of the suggestions and will do a little research.
