Long Island Weather: Heavy Downpours Possible Through Friday

A storm with the potential to produce heavy downpours across Long Island has forecasters warning of possible flash flooding Thursday night through Friday, according to the Upton-based National Weather Service.

Scattered showers are expected Thursday afternoon and heavier rainfall could start falling later in the evening, meteorologists said.

Forecasters did note, however, that areas most likely to be impacted by flash flooding are the Lower Hudson Valley, southwestern Connecticut and northeast New Jersey and New York City. But “it will be possible across the entire tri state area,” the NWS said in a statement on its website.

Heavy downpours could last through Friday, forecasters said.

There’s also a chance of showers and thunderstorms Saturday morning before partly sunny skies take over with temperatures topping off at 86 degrees.

Sunday’s forecast would appear to be more appealing to Long Islanders looking to enjoy summer’s final weekends. Forecasters are calling for mostly sunny skies with a high near 82 degrees.
