There will be a mix of clouds and sun Wednesday on Long Island but only a slight chance of rain before possible showers and thunderstorms Thursday, according to the National Weather Service.
Temperatures on Wednesday will be in the low 80s, said Dominic Ramunni, a meteorologist with the weather service, adding that the skies will be a mixture of clouds and sun before a change in the weather.
There's a 20% chance of showers and thunderstorms, the weather service said.
By Thursday, a warm front will move in early in the day, which Ramunni said, "could bring with it a few showers and an accompanying cold front that will move through later in the evening that will also bring with it at least a chance for some showers perhaps a thunderstorm or two."
The temperatures Thursday will be 77 degrees before dipping to 68 at night, the weather service said.
"Behind that front, Thursday night, we’ll start to see some dryer air into the region Friday afternoon," Ramunni said. "In my opinion, it’s going to feel gorgeous on Saturday."
July’s mean temperature is 73.9 in Islip, according to the weather service’s records, which began in 1963. The maximum is 81.7 and the minimum is 66.
