Long Island weather: Chance of thunderstorms Tuesday evening, but mostly for south of LI

Tuesday evening brings slight chances of showers and thunderstorms for parts of Long Island, but forecasters say much of that action is expected to stay further to the south.

Yes, the chance is slight, and it doesn’t look to be amounting to much, said Geoff Bansen, News 12 meteorologist.

A “low end” chance for precipitation exists, particularly for Nassau County and areas of western Suffolk for around the 6 to 10 p.m., range, said Joe Pollina, National Weather Service meteorologist in Upton. That would be to see some scattered showers and storms, make that isolated, for areas to the east.

And, it’s always good to remember that all thunderstorms produce lightning. “If you hear thunder, you're close enough to be struck,” the weather service says.

Vulnerable areas along Nassau County’s South Shore bays could see some localized minor flooding, according to a flood statement in effect from 7 to 10 p.m.

We’re getting into that “hazy, hot and humid pattern, as we head into the Fourth,” Bansen said. “It could be “pretty steamy through the end of the week.”

A quick look at Wednesday shows mostly sunny skies and highs in the mid-80s, as humidity picks up.

Thursday, the Fourth of July, could bring patchy fog in the morning to some areas, with most of the day delivering a mix of sun and clouds. That’s as temperatures head up to the mid-80s – a few degrees cooler on the East End and South Shore. Still, there's a slight chance for an evening thunderstorm in Bansen's forecast. 

There’s also potential for a repeat of that patchy fog Friday morning, with partly sunny skies, some mugginess and temperatures again reaching the mid-80s or so.

Chances of showers enter the picture Friday night, with showers and thunderstorms likely for Saturday, the weather service said. As for that humidity, it's to be most oppressive on Saturday, Pollina said.

Sunday, with partly sunny skies, is expected to reach the low 80s, with Bansen indicating potential for some scattered showers and storms.
