Long Island weather: Sunny, high temps in 80s

Long Islanders can expect continuing warmer-than-normal temperatures, at least through Thursday, forecasters say.

Monday was forecast to head up to around 83 degrees, the National Weather Service said, with 71 considered the norm for the day. Tuesday is looking at highs of around 78 at Long Island MacArthur Airport; Wednesday, 80; and Thursday, 78.

Sunday’s high at the airport reached 89 degrees, well beyond the record of 83 set in 2009, according to the weather service. The average temperature for the month at the airport, as of day-end Sunday was 69 degrees, which is 2.3 degrees above normal.

That’s as, “after a cool start to September, above normal temps have been the norm over the past week and a half,” the weather service said Monday in a tweet.

Rich Hoffman, News 12 Long Island meteorologist, said it feels more like July 25 than Sept. 25.

Long Island finds itself under a high pressure area that’s been keeping conditions unseasonably warm, said Faye Morrone, weather service meteorologist in Upton.

Later in the week, she said, a cold front will be coming through, causing the high to “gradually slide off shore,” as well as helping to push what’s now Hurricane Maria out to sea.

Look for some areas of fog Monday night into Tuesday morning, followed by some sun and clouds Tuesday, Hoffman said.

Still, despite the summery conditions, better be careful if you’re thinking of a trip to the beach, as there’s a high risk for rip currents at ocean beaches, which the weather service says probably will continue through at least Thursday and possibly Friday.

That’s as swells from Maria on Monday “will be increasing along the Mid-Atlantic and southern New England coasts,” the National Hurricane Center said. “These swells will likely cause dangerous surf and rip currents at beaches in these areas through much of the week.”

Expect “rough seas along South Shore as Hurricane Maria passes to our south and east,” News 12’s Hoffman said.
