Discussion
It turns cooler today in the Philly metro region following the overnight passage of a cold frontal system and temperatures are likely to top out near the 80-degree mark for afternoon highs as compared with the middle 90’s on Wednesday. With the frontal system stalling out in rather close proximity, the weather here will remain somewhat unsettled into Friday with an isolated afternoon shower or thunderstorm and then likely another round of showers and thunderstorms from later tonight into tomorrow...some of the rain can be heavy at times.
Another cold front will bear down on the Mid-Atlantic during the day Saturday and this “primary” frontal system will likely bring more showers and thunderstorms to the area from later Saturday into Saturday night. A “secondary” cold front will then drop south and east into the Mid-Atlantic region from later Sunday into Monday and it can result in some additional shower activity; however, I am not expecting any late weekend rainfall to be heavy or organized like that of earlier in the weekend. A cool, dry blast of air arrives on Monday, Labor Day, featuring below-normal temperatures and very comfortable humidity levels for the first half of next week.
