10:00 AM | **First extended heat wave of the summer in the Mid-Atlantic region lasts through Sunday…a run to 100 degrees on the table in some spots this weekend** — Arcfield Weather

The weekend will feature high heat and humidity with temperatures likely climbing well into the 90’s on Saturday afternoon and a surge to near 100 degrees is not out of the question for Sunday afternoon. The next cool frontal system should bring us some shower and thunderstorm activity on Sunday night and/or Monday.  Following the passage of that next cool front, it looks like there will be relief in the temperature department on Tuesday and Wednesday with highs generally confined to the 80’s.

If 100 degrees is actually reached this weekend in the I-95 corridor, it would be the first time in a couple of years in some spots and in as many as ten years in other sites.  For example, BWI Airport in Baltimore, MD hit the century mark just two years ago on July 20th of 2020. In Washington, D.C., the last official 100 degree reading came during August of 2016 at Reagan National Airport (DCA). 

In Philly and New York City, one has to go back ten years for the last 100 degree (or higher) readings. On July 7th, 2012, Philly (PHL) officially topped out at 101 degrees and on July 18th of the same year, New York City’s Central Park reached 100 degrees.  Interestingly, while it has been about ten years since 100 degrees has been reached in Philly and New York City, those 2012 readings actually marked the third consecutive year of 100+ degree days in the two metro areas.  Philly topped out at 103 degrees on July 22nd of 2011 and at 103 degrees on July 7th in 2010.  In New York’s Central Park, temperatures reached triple digits on back-to-back days in both 2011 and 2010 (7/22-23/2011: 104, 100 degrees; 7/6-7/2010: 103, 100 degrees).
