All the back and forth about a coastal low has brought us to the original idea that the weather over the next several day will be fine. Indeed Friday through much of Monday will be good making this the 5th weekend in a row of good weather. Today and Saturday there will be a bit of a northeast wind and that will keep tempertures down just a bit but it should still make the 80s. The beaches will probably be in the mid to upper 70s with the wind off the water. Other than occasional clouds there are no weather problems into Monday.
The next weather system arrives late Monday with showers and thunderstorms into all of Eastern Pennsylvania by evening and everywhere else after midnight. This should last through most of Tuesday before the front moves off shore and then another dry air mass arrives for Wednesday and Thursday. It seems to be a pretty straight forward forecast. 80s will be here Monday and Tuesday and then lower 80s for the midweek period. No sign of 90 degree weather returning anytime soon.
