Big time F, KATL has been below freezing five times so far this meteorological winter season, 9 if you count November, which is absolutely abysmal. December was 4 degrees above average, which is pretty normal these days. January is 6 above average thus far, and is likely to stay at least 4 or 5 above average with temps forecasted the next 5 days. Grading the winter season based on snowfall outside the mountains isn't really my thing since none of these areas average anything significant in a season, I base it more on seasonal forecasts and departure from average temperatures.
