Your official weather forecast for long July 4 weekend

Get ready to crank up those air conditioners. And keep your eye on the sky if you're heading to any parades or fireworks displays during the long Fourth of July weekend.

Forecasters say it's going to be a steamy and sticky holiday weekend with occasional threats of spotty afternoon and evening showers and thunderstorms. In other words, it should be "a very summer-like pattern," said Lance Franck, a meteorologist at the National Weather Service's regional forecast office in Burlington County. 

With a dome of high pressure stationed near Bermuda, known as a Bermuda High, a tropical mass of hot and humid air will be pushing its way from the south and west up into the Mid-Atlantic and Northeast region, Franck noted. During the weekend, a weak frontal boundary will have the potential to spark some scattered showers and thunderstorms.

How chilly is the Atlantic Ocean this week?

As of now, it appears the biggest threat for stormy weather will be Saturday, and the threat of severe storms is higher in northwestern New Jersey than along the Jersey Shore, according to the Weather Service's Storm Prediction Center

High humidity and dangerous rip currents

Two of the most noteworthy weather trends the next couple of days will be the uncomfortable humidity in inland areas --  particularly in western counties like Mercer, Burlington, Camden and Gloucester -- and strong rip currents along the Jersey Shore.

The heat index, how hot it feels when the air temperature is combined with the humidity, is expected to rise to the mid-90s by Friday afternoon and in the mid- to upper 90s by Saturday afternoon along the urban corridor from Trenton to Philadelphia, Franck said.

As for the dangerous rip currents, the threat was low Thursday morning but will rise to a moderate risk Thursday afternoon and early evening at the Jersey Shore as winds and waves increase in intensity. The threat is expected to remain moderate on Friday.

"We're very concerned about late this afternoon and into this evening, given the conditions we're expecting during that timeframe," Franck said. His advice to swimmers at the Shore: "Feet should remain in the sand unless lifeguards are in the stand."
