There's a chance that showers or a scattered thunderstorm could scramble your Fourth of July plans, the National Weather Service said.
But not for the long haul.
"But there's also the chance most areas won't even see showers and thunderstorms," said Pollina, noting the chances for precipitation are relatively low. "It basically will not be an all-day event."
Rain is most likely to fall in the form of scattered showers between 4 p.m. and 9 p.m., the service said.
Total accumulation is not expected to be more than a quarter of an inch, and clear weather is likely to move in by nightfall, the service said.
High temperature for the holiday is expected to be around 87 degrees, with a low of 72 for Wednesday night.
The weather stays most hot -- in the high 80s to low 90s -- until Saturday night, when the chance of showers and thunderstorms again is about 30 percent.
