The last few days took a massive bite out of the monthly departure for DFW, as February will only end up -1.2*F below average.
As far as winter on the whole (Dec - Feb), it ends up with an average temp of 48.6*F (+0.3*F above average).
Snowfall-wise, the season (Dec - Feb) ended up being above average with a total of 2.6", all of which fell with the Winter Storm on 1/9 (and was partially sleet contaminated).
