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.

The National Weather Service took to X, formerly known as Twitter, to announce a flash flood warning for parts of Berks County until 11:30 p.m.

You probably noticed the difference during the day on Thursday, as it was hot and humid with highs pushing near to 90 with feels-like temperatures in the mid-90s.

It's going to feel steamy on July 4th.

The greatest chances for showers and storms could happen Thursday night with an approaching cold front.

While it wasn't a washout for July 4th, there is still a possibility of scattered storms. Those storms could affect fireworks displays.

It could be possible that some neighborhoods are getting rained on while people in other places view fireworks in a dry evening sky.

Luckily, much of the rain could move through before fireworks blast off on July 4.

The possibility of severe weather is most prominent through parts of Chester County and into northern Delaware and parts of western South Jersey.

The severe weather threat is more limited than originally feared.

Excessive rainfall is a more likely impact from this system with the possibility of lots of rain falling in a rather quick period of time throughout much of the Philadelphia region, including the city, Pennsylvania suburbs, New Jersey suburbs and northern Delaware.
