Pittsburgh Near All-Time Record Monthly Snowfall

Feb. 25 Update: The record was broken today.

Evening Update: Although Pittsburgh's average temperature of 23.3° for February so far is 5.8° below normal, it's significantly higher than the 20.9° recorded in 2007. Only 14" of snow fell that month, a little over a third as much as this year.

On the other hand, the average in January 1978, the current snowiest month, was 0.7° colder. That month, in turn, was over 11° warmer than the previous January, in which more than a foot less of snow fell.
