Tracking rain on the Fourth of July

We enjoyed pleasant weather throughout Pennsylvania, New Jersey and Delaware Monday through Wednesday, with low humidity and plenty of sunshine.

But unfortunately, changes are expected that could impact Fourth of July celebrations.

Later Wednesday, high pressure that was over our area shifted offshore, bringing more humid air and increasing chances of showers and thunderstorms -- especially come Thursday evening.

You’ll notice the difference during the day Thursday, as it will be hot and humid with highs pushing near to 90 with feels-like temperatures in the mid-90s.

The greatest chances for showers and storms happen Thursday in the late afternoon and early evening with an approaching cold front.

While it doesn’t look like a washout for July 4th, there is a possibility of scattered storms. Those storms could affect backyard barbeques, pool parties and fireworks displays.
