Wednesday brought sunny skies with a high of 88 degrees at Long Island MacArthur Airport — equaling the airport’s hottest temperature so far this year.
Unofficial reports came in, too, of 90 degrees in Calverton, Riverhead and Locust Valley, said Jay Engle, National Weather Service meteorologist based in Upton.
The last time it was that hot at the airport was on May 25, when the thermometer topped out at 88 degrees.
Earlier in the day, News 12 Long Island meteorologist Rich Hoffman said conditions Wednesday would have folks scrambling for ways to stay cool.
Remaining in effect through 11 p.m. is an air quality alert issued by the state Department of Environmental Conservation.
The alert says the Air Quality Index for Wednesday will be higher than 100. Index ratings of more than 100 mean levels of different air pollutants can have adverse health effects for those with respiratory issues, including asthma.
Hempstead Town, meanwhile, is opening 15 cooling centers, and keeping its 10 pools and eight beaches open an extra hour through Friday “to help keep residents safe and healthy during the current snap of hot and steamy weather,” Supervisor Anthony Santino said in a news release.
Hoffman said that higher than normal temperatures will be around into the weekend.
Thursday is a mix of sun and clouds, humid, and with a chance of scattered showers and thunderstorms developing in the afternoon, Hoffman said.
Highs in the low 80s are expected for the East End, Engle said, moving up closer to 90 for areas farther to the west. And, yes, humidity can reach high — but not oppressive — levels.
