Weather Rewind: December 25-31, 2011

Another warm week last week in the Delaware Valley -- the last week of 2011 closed out on a mild note as temperatures were 7.6 degrees above average, buoyed by our toasty days on Friday and Saturday (55 and 59 for highs respectively, as well as the rainy and mild Tuesday (58 for a high).   Those three days effectively accounted for much of our temperature departure last week.   Our "November in December" theme (you'll see me repeat this a bit more later on today) ran much of this month, with mild stretches knocked back by small touches of typical winter.

Typical winter will at least last more than a day or two this week.

Rainfall was confined to Tuesday where the region picked up between a half inch and an inch of rain from a shield of rain that moved through during the afternoon and early evening.  Winds gusted to 51 mph at the Airport on Tuesday evening with a squall line that developed and moved through the western suburbs, Philadelphia, Delaware, and South Jersey just after the dinner hour.

Nationally, 2011 will shape up as mild for the eastern two-thirds of the country, warmest (and driest) in Texas on the whole and coolest in the Pacific Northwest.  The coolest in the West is typical for a La Nina style pattern...what wasn't typical was the amount of rain that fell in the Ohio Valley and Northeast (record setting years for many locations besides us).
