Recapping November 2011

November 2011 was a mild and somewhat wet month on the whole -- temperatures in Philadelphia averaged out to 51.3 degrees, 3.7 degrees above our current averages and 5th warmest November since 1872.   Much of the warmth was centered in the last ten days of the month where temperatures averaged nine degrees above normal, including a rare 70 degree day in Philadelphia during the month of November (this past Monday).   Temperatures in Allentown (9th warmest), Wilmington (6th), Atlantic City (6th), and Mount Pocono (2nd) were also mild in comparison to the historical norm for our region and among the ten warmest in their climate records.

Rainfall for the month ended up at 3.87" -- just shy of an inch above normal for Philadelphia for November.  While not wet on the whole, the last two weeks of the month provided the lion's share of the rains for the month between three soggy storms that brought at least a half inch of rain in each of them, with the middle storm bringing over two inches of rain to the Delaware Valley.   The combination of rain between September, October, and November buoyed Philadelphia to the second wettest meteorological autumn on record, trailing just 1999 (which had a slightly more wet September going for it) in all-time rains.
