NEW YORK (WABC) -- Strong evening thunderstorms could wreak havoc on July 4th fireworks celebrations across the Tri-State area on the final day of a dangerous heat wave.

A Severe Thunderstorm Warning has been issued for portions New York City, the Hudson Valley, and northern New Jersey. A Severe Thunderstorm Watch is also in effect for New York City, New Jersey and portions of the Hudson Valley. Any storm has the potential to produce damaging winds, downpours and even some hail.

The timing of the storms could coincide just as fireworks kick off across the region, including New York City, which could see storms move in during the 9 p.m. and 10 p.m. hour.

The Macy's Fourth July Fireworks start time was moved up from 9:25 p.m. 9:02 p.m. as a result of the incoming storms.

The silver lining is that the storms will finally break the four-day heat wave, as temperatures fall back into the 80s on Sunday with a chance for showers developing later in the day.

More widespread showers and thunderstorms are expected Sunday night into Monday, bringing the most significant relief from the oppressive heat and humidity.

Anyone heading outdoors for holiday festivities should stay hydrated, monitor air quality conditions, and keep an eye on the weather later Saturday as storms may become heavy and dangerous in some locations.

Extreme heat causes NJ Transit nightmare during rush hour

NJ Transit is asking its rail customers to find another way home if possible, cross-honoring on NJ Transit or private carrier buses, PATH, or even NY Waterway ferries, as electric trains are being slowed by the heat.

"What we want people to do is use all the methods we are making available...to try and use all of those systems to get home," NJ Transit President and CEO Kris Kolluri. "It's the most excessive temperatures we have had this year."

CeFaan Kim has the latest from Penn Station.

Sagging wires temporarily stopped two trains during the commute. In one instance, a rescue train was deployed to Harrison to get about 300 customers back to Hoboken Terminal. It took about 45 minutes to tow the disabled train back to Hoboken. During that time, the air conditioning was on, and police were distributing water on the train.

Meanwhile, the Hackensack Drawbridge, a century-old bridge that crosses the Hackensack River between Secaucus and East Rutherford, got stuck open for 25 minutes because of the heat, causing delays. NJ Transit decided not to open any more rail bridges for the rest of Thursday's commute as a result.

Amid the extreme temperatures, smoke was also seen at Hoboken station after 5 p.m. after the heat sparked a fire, sending some riders running from the platform. NewsCopter 7 was over the scene where smoke was seen on track 7.
