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.
