Philadelphia, PA – Drivers and evening commuters across the I-95 corridor could face sudden downpours and damaging wind gusts as thunderstorms rapidly develop by mid-afternoon Wednesday.
According to the National Weather Service in Philadelphia/Mount Holly, widespread showers and thunderstorms are expected to expand between 3 p.m. and 10 p.m. Wednesday, with a 60 to 80 percent coverage rate. While not every storm will turn severe, isolated cells could produce wind gusts up to 60 mph, small hail, and rainfall rates near 1 inch in a short period.
The greatest risk zone stretches from Philadelphia through Wilmington and into South Jersey, including Camden, Vineland, and Atlantic City. Roads like I-95, I-76, and the Atlantic City Expressway could see reduced visibility under 1 mile during peak rainfall, especially during the evening commute.
Emergency managers warn localized flooding may develop in poor drainage areas. Residents are urged to secure outdoor items, charge devices ahead of potential outages, and move indoors immediately if thunder is heard.
Temperatures will drop sharply after the storms, with a cold easterly breeze setting in by Thursday morning and daytime highs struggling to leave the 40s.
Storm activity may linger overnight, and additional advisories remain possible through early Thursday.
