Weather Rewind: May 13th-19th, 2012

Temperatures last week averaged out to 4.1 degrees above average for the middle of May, buoyed by a warm and humid start and a warm and dry finish.  Despite Monday being the coolest day of the week temperature-wise, the presence of humid air and showers around the region at times in the afternoon helped provide for a day that still ended up above average thanks to the daily low of just 64.

Rounds of rain and some thunder moved through the region on Tuesday and late Tuesday night -- bringing upwards of two inches of rain to parts of the region.  The rainiest parts of the area were to our north and northwest while parts of Delaware and South Jersey saw less than an inch of rain from the midweek system. Month-to-date, rainfall has been much closer to average around the Philly metro and has exceeded average across Central into Northeastern Pennsylvania.  However, it does remain dry across Southwest New Jersey and much of Delaware, with rainfall generally between 30 and 60 percent of normal month-to-date south of town.
