Cape May, southern Cumberland County, and Delaware are under a slight risk of severe weather today and tonight.
Additional threats include downpours, sizable hail, and isolated tornadoes are not out of the question.
The remainder of the week remains unsettled, but as of now, the severe weather threat looks to unfold today.
It appears a frontal boundary will stall over the region on Thursday.
Shower and storm chances will be concentrated closer to Thursday afternoon and evening, which is likely to be south of Philly, but this could shift given its final position.
Humidity returns for all on Friday as the front lifts north again along with a hit-or-miss thunderstorm chance.
Rain and storms are possible on Saturday before a stronger cold front sweeps all the way through and reduces the high heat and humidity by Saturday night.
TROPICS
Tropical Storm Cristobal has formed in the southern Gulf of Mexico. Cristobal is forecast to meander around near its current position over the next several days before making a move north into the open waters of the Gulf of Mexico this weekend.
Slow strengthening is expected.
Cristobal is predicted to pose a threat to the United States Gulf Coast by the end of the weekend and early next week. Cristobal is now the earliest third named storm on record.
The old record was Colin, which formed on June 5, 2016.
