Reviewing The First Half of March

Through yesterday, Philadelphia's on pace for the 4th warmest March since 1872.  We're averaging a temperature of 49.5 degrees so far this month, or 8.2 degrees above average.   Only 1921, 1945, and 1946 were warmer throughout the course of the month.  Needless to say, the month has been quite May-like as temperatures have been 70 or above four times so far this month...equal to the number of 70 degree days we've seen in 2003 and 2010, which are the last two years we've seen four or more forays into the 70 degree realm.  The most 70's in a particular month is nine in 1921 and 1945...this week might give us a real run at approaching that mark.

Despite the uber warmth we've seen in much of the last week around here, there have been occasional chill shots early in the month.  We had lows in the 20's on the morning of the 6th and the region was below average on three occasions so far out of the first two and a half weeks of the month.  It hasn't been quite wall-to-wall warmth although it sorta feels that way.

In terms of rainfall, it has been rather dry this month -- just 0.42" of rain so far...about an inch and a half below average for the region, which continues the dry trend we've seen in much of the Mid Atlantic since December.
