I'm not sure what you call cold, but I worked in Boulder years ago and can remmy going to work when it was twenty below zero. I also remmy snow staying on the ground from T'giving to New Years. One year had knee deep snow with drifts to top of the fence. It took a week to melt... in March.
My father grew up near OKC and I've been there several times. Doubt that OK gets THAT cold. You don't mind. Right?? 
Where do you want to move?
