Weekend storm likely for Jersey Shore, Philadelphia region. Here's the weather forecast.

Friday morning's story was the chilly weather across the Philadelphia region, but we're looking ahead to two NEXT Weather Alert Days on Sunday and Monday as a weekend storm will begin to form from a coastal low.

Overnight frost and freeze warnings have expired in the Philadelphia area, after we had the coldest morning we've felt since April 18. In the city, temperatures dropped to 45 degrees, while several spots in the Lehigh Valley and Poconos went below freezing, signifying the end of the growing season there (meaning no further frost or freeze warnings will be issued for those areas).

Bus stop forecast for Friday, grade of B, sunny and 46 at 8 a.m., 61 and partly cloudy at noon, 64 and partly cloudy at 3 p.m.

The rest of our Friday is a pleasant fall day with mixed clouds and sunshine and highs in the 60s. The normal high for this time of year is 70 degrees.

Weekend storm forecast

Looking ahead to the weekend, it's time to make your backup plans if you have anything outdoors set for Sunday, as a strong area of low pressure (a coastal low) will be developing south of our area and moving north. 

Impacts will be widespread but felt the greatest at the Jersey Shore, where high winds will be up to 60 mph and up to 3 inches of rain will fall. 

In addition, seas will be extremely rough, with waves potentially 15-20 feet in spots — so flooding is likely, especially around high tide. Coastal flood alerts are already in effect.

Closer to the I-95 corridor, winds will be lower but still significant, closer to 40mph, and 1 inch of rain will be likely. Power outages are a possibility and there could also be very slow travel Sunday and Monday. Your morning commute Monday could be very slow.

By Tuesday, the system moves east and rather quiet weather settles in with a slight warmup by midweek.

Here's your 7-day forecast:
