January finished about 3 degrees below normal in Philadelphia, and it was quite cold in much of the nation
The National Climate Data Center reported today it was the chilliest January since 1994, a month that may be a first-ballot selection in the U.S. winter hall of fame.
January 1994 marked the last time that the temperature fell below zero in Philadelphia, and it was a month of memorable local ice storms.
Nationally, the climate center calculated that the January 2011 temperature was 0.8 degrees below the 20th Century average. In the 117-year period of record, it was the 37th coolest.
