Philadelphia under heat advisory Sunday, more severe storms with strong winds and hail possible this afternoon
PHILADELPHIA (CBS) -- Some scattered showers and storms continued into Sunday morning across the Delaware Valley, while South Jersey and the shore points were hit with torrential and potentially flooding rain early in the day.
Some patchy fog could develop across the area this morning, especially along the shore where the warmer air will cross the much cooler ocean water, which is in the 50s and 60s. Skies will be mostly cloudy with afternoon breaks of sun and highs in the 90s accompanied by a feel-like temperature between 100-103 degrees.
More potentially severe storms Sunday night
The expected heat has triggered a heat advisory from 11 a.m. until 7 p.m. for all areas adjacent to the I-95 corridor, including Philadelphia, Wilmington, Delaware and Trenton, New Jersey.
A flash flood warning has also been issued for Cape May, Atlantic and Cumberland counties through 11:30 a.m. In just a few hours Sunday morning, between 1-3 inches of rain has fallen across the region.
Because of the extreme heat and chance for more severe weather Sunday night, we've declared Sunday a NEXT Weather Alert Day.
Sunday afternoon and evening, scattered showers and strong to severe storms will once again develop across the Delaware Valley ahead of a cold front. Our entire area is under a slight risk of severe weather, or Level 2 on a five-point scale.
The main threats are damaging winds, heavy rain with possible flash flooding and large hail. While the chance that a tornado will develop remains low, we can't completely rule out the possibility.
The first line of storms looks to move across the Philadelphia region between 2-3 p.m., but more storms will develop in the afternoon. The chance for severe weather will continue between 3-5 p.m., possibly in some areas until 7 p.m.
Cooler start to the week
Following Sunday's storms, cooler and more comfortable conditions arrive on Monday and Tuesday, where we'll see sunshine and highs in the low 80s.
On Wednesday, we warm up again to near 90 with partly sunny skies. Then for the Fourth of July it'll be muggy and hot with highs in the low 90s and a feels-like nearing 100.
Another heat advisory and NEXT Weather Alert may be needed for Thursday, so stay with the NEXT Weather team this week for updates. Showers and storms are also possible Thursday afternoon and evening.
