First Call Forecast for Rainfall Possibilities During 4th of July Fireworks in Pennsylvania

First Call Forecast for Rainfall Possibilities During 4th of July Fireworks in Pennsylvania

The Fourth of July is just two days away, and we are looking at the potential for rain in parts of the state Thursday evening. Friday evening doesn’t look too much better, but we will keep you updated on that.

Showers will move through the state Thursday afternoon, and will begin to weaken as they run into the high pressure. Even still, some rain showers may persist through the evening and unfortunately during fireworks.

The HI-Res NAM model suggests some showers will linger in Southwest PA and a greater portion of Eastern PA. We suggest looking at the radar to find a window of dry conditions. Below is the Hi-Res NAM Future Radar for 6 PM Thursday through 12:00 AM Friday.

Most likely, the radar will not look exactly like that. Often times precipitation moves through ahead of schedule, so it may be a bit farther east. We will have another update to the forecast on Wednesday evening!

4TH OF JULY FIREWORK RAINFALL CHANCES

Area A: 60% chance of rain for fireworks around 9:30pm July 4th

Area B: 40% chance of rain for fireworks around 9:30pm July 4th

Area C: 20% chance of rain for fireworks around 9:30pm July 4th

As of now, we don’t recommend cancelling 4th of July firework shows anywhere. Stay tuned for another update on Wednesday!
