Hazardous Weather Outlook, Thunderstorms In NJ (UPDATE)

July 4th was great, but the outlook isn't so rosey for New Jersey on July 4th weekend.

The National Weather Service has issued a hazardous weather outlook throughout New Jersey, saying thunderstorms on Saturday may produce locally heavy rainfall. More storms could happen on Saturday and Sunday (see forecast below).

Some of the rain was already happening in parts of the state on Friday.

The forecast could delay any kind of Indpendence Day fireworks, parade or celebration this weekend. Read more: NJ Fireworks 2019: See Local Fireworks On July 4th Weekend

A surge of moisture and a slight southward dip in the jet stream will trigger a daily eruption of showers and thunderstorms, according to AccuWeather. Some areas could be hit with multiple downpours per day.

On Friday the northeastward surge of showers and thunderstorms began in earnest, according to AccuWeather.

"There is going to be a lot of water pent up in the atmosphere into at least Saturday which can be released in the form of torrential downpours," AccuWeather Senior Meteorologist Brett Anderson said in an AccuWeather release.

On Saturday and Sunday, downpours are likely to persist from southern Ohio, southern Pennsylvania and much of New Jersey on south, according to AccuWeather.
