A flash flood warning was in effect across the Philadelphia area on Sunday morning as torrential rain and lightning swept through the region, threatening to disrupt preparations for the Philadelphia Eagles’ season opener.
The National Weather Service issued the warning until noon for Philadelphia, Trenton, Levittown and surrounding areas of South Jersey and Delaware County. Heavy downpours caused localised flooding on roads, while nearly an inch of rain was reported in parts of the Lehigh Valley.
The heaviest rain was moving east, but intense showers were expected to continue for a further one to two hours across Philadelphia, Delaware, Salem, Camden, Gloucester, Burlington and Mercer counties.
When will the Philadelphia rain clear?
Forecasters said conditions should improve by early afternoon. Radar was expected to clear, with only isolated showers remaining before the rain largely moved away for the rest of the day.
That should allow the weather to settle before the Eagles’ game, with sunshine returning around kick-off and temperatures rising into the 80s Fahrenheit, or roughly 27C to 29C.
However, the morning storm will leave behind high humidity, meaning conditions are likely to feel hot and uncomfortable for supporters at the stadium and tailgaters in nearby car parks.
Temperatures are expected to fall into the 60s Fahrenheit overnight as the humidity eases. Monday should bring mostly sunny conditions and lower humidity, with a possible brief shower during the morning commute, before dry weather returns from Tuesday through Thursday.
