Discussion
It turned out to be the wettest June ever recorded in some Mid-Atlantic locations (e.g., Philly, Wilmington, DE) and July is starting out on a very wet note as well. Philly Int'l Airport ended up with a record 10.56 inches of rain for the month of June and it was the sixth wettest month ever. Torrential rain has already occurred this morning in many Mid-Atlantic locations and more is on the way, but there are signs that this very wet pattern will evolve into a primarily hot pattern by the end of the week, and the threat for rain will gradually diminish as the week progresses.
The combination of a strong upper level low pressure system over the Ohio Valley and an extensive surface high pressure system off the east coast will keep a moist southerly flow of air in place along the east coast for the next couple of days. This type of wind flow will bring copious amounts of tropical moisture up the east coast from the Gulf of Mexico and the result will be more torrential rainfall right into mid-week. By later this week, however, the showers and thunderstorms will become more and more widely scattered and the main weather story will likely be the developing heat as high temperatures should climb to 90 degrees or above.
