A storm system making its way from the Midwest is expected to hit the Philadelphia region Sunday, bringing with it a chance of severe weather throughout the region.
The NBC10 First Alert Weather team has also issued a First Alert from 4 p.m. to 12 a.m. for the greater Philadelphia region as the system creates the possibility of scattered but powerful and fast-moving storms.
With a combination of heat and humidity throughout the day, as well as an expected warm front, you can expect scattered thunderstorms, heavy rain, lighting, possibly damaging winds and even hail.
The Lehigh Valley will get the first surge as showers begin shortly after 4 p.m. The storms then move eastward, arriving in Philadelphia and Trenton between 5 p.m. and 7 p.m. The system will reach the Jersey Shore between 7 p.m. and 8 p.m.
While the severe weather will peter off Sunday evening, there could still be some lingering showers overnight.
Things should improve by Memorial Day, however, as temperatures remain hot, but the humidity dissipates.
