Long Island weather: Temps to soar into 80s Wednesday

The National Weather Service said a stretch of

The National Weather Service said a stretch of on-again, off-again rain through most of Tuesday, May 24, 2016, with thunderstorms possible, is expected.

Get ready for a little blast of summer weather, perhaps with a nod to the upcoming Memorial Day weekend — the unofficial start of the season.

Under sunny skies Wednesday, temperatures are forecast to soar into the low to mid 80s, well above the norm for this time of year, said Carlie Buccola, National Weather Service meteorologist based in Upton.

“A dramatic warmup is expected across the entire region” for Wednesday, the weather service said in its Tuesday morning forecast discussion.

Long Island MacArthur Airport is looking at highs of about 84, with temperatures slightly ticking up as you move closer to New York City, where 86 is forecast for Central Park, the weather service said. As is often the case, the East End is a little cooler, with 81 forecast for Montauk.

The New York State Department of Environmental Conservation and state health officials Tuesday issued an air quality health advisory due to expected high ozone levels for Long Island, and the New York City metro area on Wednesday.

The advisory will be in effect from 11 a.m. to 11 p.m.

Young children, those with respiratory conditions and older people are advised to curtail outdoor activities when ozone levels are the highest, in the afternoon and early evening, the alert said.

Normal highs for the last week of May range from 70 to 72 degrees, with 80 more akin to the end of June, says Jessica Spaccio, climatologist with the Northeast Regional Climate Center, based at Cornell University.

The last time the airport saw 80 or above was Sept. 29, 2015, when 81 degrees was hit, she said.

Actually, we’re a little overdue, as May 6 is the average date to reach or exceed 80, she said, based on data going back to 1984. (Of special interest quite possibly to weather nerds only, the latest date to see the first 80 was June 4, 1984, the first year the weather service started maintaining records for the airport.)

On Thursday, skies turn a bit cloudy, but daily highs range from the upper 70s to low 80s, says News 12 Long Island meteorologist Rich Hoffman. There’s a slight chance of rain for the overnight hours.

A look ahead to the long weekend from Friday through Monday shows dry skies, with seasonable temperatures in the low to mid 70s, said Jay Engle, also a weather service meteorologist in Upton. Forecasters will be keeping an eye on a tropical disturbance, he said, but so far the models are keeping it “suppressed to the south through the holiday weekend.”
