Philadelphians hoping to enjoy festivals and fireworks on the Fourth of July should be in luck: The city likely won't be celebrating the nation's independence in one of the torrential rainstorms that's hit the region on near-daily basis for the past week.

The National Weather Service says Independence Day in Philadelphia should be mostly sunny, with a slight chance for showers and thunderstorms in the afternoon. But forecasters say there's just a 20-percent chance of rain on Thursday.

Though precipitation will be moving away from the Philly area, "temperatures and humidity values will begin to rise," according to a weather service forecast discussion.

The day is expected to be hot, with a high temperature near 91 degrees.

Those hitting up early Independence Day festivities or traveling out of town today face a somewhat greater chance of rain. The weather service says to expect scattered showers and thunderstorms, mainly before 7 p.m., with a 40-percent chance of precipitation.

Some of today's storms could lead to heavy showers, the forecast discussion says, but "the potential for widespread excessive rainfall will be less than previous days."

The high temperature today is slated to reach 86 degrees and forecasters say to expect a humid day.

And that heat and humidity is expected to continue over the weekend, when heat indices could reach the upper 90s.

Friday, Saturday and Sunday should all be mostly sunny, forecasters say. The weather service expects the high temperature to reach 93 degrees on Friday and Saturday and 92 on Sunday.
