We had our first cold blast and snowfall of a few inches about the 1st of Dec. One day it was 75 and the overnight low was 65 and the next night it was 25, the next was 12 (all F.) We still have traces of snow in protected and shaded locations including our roof on the north side.
Today and tomorrow are forecast to be in 50's.
After all, this is Oklahoma where the wind comes sweeping down the plains (sometimes all the way from Canada or the north pole.)
The best argument I ever lost to my wife was aver a heated and air conditioned cab on our new tractor. I just love it. I could stand some more A/C some of the time but the heater is ARCTIC ready. Even when it is below 10F yoiu can't run the heat too high as it will drive you out. A heck of a heater.
