Discussion
More rain is headed towards the Philly metro region and the highest amounts are likely to take place from later tonight into tomorrow morning and across the southern half of the area (e.g., Philly, Chester County, Delaware County). Low pressure will form along a stalled out frontal boundary zone and push towards the Mid-Atlantic coastline over the next 24 hours and rain should overspread the area from southwest-to-northeast and strong thunderstorms can be mixed into the picture. Given the recent heavy rainfall, flash flooding is a concern; especially, across southern sections of the Philly metro region. Temperatures will remain fairly warm today with highs at or slightly above the 80 degree mark, but stiff NE winds on Saturday – typical of a nor’easter - could confine temperatures to the lower 70's to go along with the rainfall. Much improvement will take place on Sunday as the storm pulls away from the Mid-Atlantic coastline.
