Another Record Setting Day...And Month...For Philly

Update, 7 PM:  We set a daily rainfall record for any day, any month, all-time in Philadelphia with 7.35" as of 7 PM...and we're probably not done with the rainfall yet as more thunderstorm activity is firing in the western burbs, moving slowly east.

For the month, now 12.33" (3rd wettest month ever, wettest July on record).

Original post follows below:

For those who like records, today sets several in one shot. First, the obvious, 5.95" of rain at the Airport through 6 PM. Most in a single day since Floyd dropped 6.63" back on September 16th, 1999. We can top six before the night's over -- might be tough to break the record but we'll keep an eye on it. Heavy rains straddle the Delaware River and I-295 corridors in South Jersey, with plenty of roads underwater across suburban South Jersey.

The city, immediate South Jersey, and Wilmington are the clear exceptions to the rule today regarding rain and thunder. Most of the region avoided getting the training of rains that stuck themselves like superglue along I-95 and I-295. Wilmington's 1.36" of rain was significant and Pottstown's 0.80" of rain was pretty hefty as well, but neither of those totals compared to the three to five inches of rain that fell around the Airport.  Northeast Philly, just 20 miles away from the Airport, picked up just 0.24" of rain through 6 PM. Amazing gradient and cutoff on today's heavy rainfall.

Today's six inch (or more) rainfall has pushed the rainfall total for June to 10.93" through 6 PM, which is not only the wettest July on record but the sixth wettest month on record in Philadelphia (since 1872).  It's also the fifth time in the last four years we've hit ten inches of rain in a calendar month, the fourth time in the last two years.
