Long Island was getting some scattered, spotty showers Thursday, as temperatures reached the low 80s and humid, forecasters say.
Given the amount of moisture in the air, any showers that do arrive could bring “brief, but torrentially heavy downpours,” said Tim Morrin, National Weather Service meteorologist in Upton. Chances of showers drop by around 8 or 9 p.m., he said. The service issued a flash flood warning for some areas Thursday night.
Then, the “heat really gets kicking tomorrow into the weekend,” said Rich Hoffman, News 12 Long Island meteorologist.
An excessive heat warning is in place from 6 a.m. Saturday to 8 p.m. Sunday. And, a heat advisory is in place from noon Friday to 6 a.m. Saturday.
We’re looking at potential air temperatures around 90 degrees Friday for much of Long Island and the mid-90s for Saturday and Sunday, as of the Thursday afternoon. That would make for a heat wave, which is three consecutive days of 90 degrees or above.
However, when we add humidity into the mix, we get what’s known as the heat index, reflecting what it’s actually going to feel like. For Friday that could amount to around 104 degrees, and that goes up to110 or so Saturday and Sunday, according to the National Weather Service.
This is dangerous territory when it comes to health and well-being — particularly for children, the elderly, those with heart/respiratory conditions and anyone working or exercising outdoors.
Long Islanders should also be aware of the danger of leaving children and/or companion animals in vehicles, even briefly, said I. Ross Dickman, meteorologist in charge of the weather service’s Upton office.
Monday brings some relief, Hoffman said, with more comfortable conditions Tuesday.
