Welcome back, summer.

Temperatures sizzled Wednesday, with a high of 88 degrees recorded at Long Island MacArthur Airport in Ronkonkoma, according to the National Weather Service.

That tied the Islip record for the day set in 1989, according to meteorologist Tim Morrin. The National Weather Service began keeping records at the airport in 1984.

High humidity made it feel like 95 degrees in parts of Long Island and hotter than 100 degrees in parts of New York City, he said.

Typically this time of year, temperatures are in the mid-70s, Morrin said.

The temperature did not break the record for the day at Brookhaven National Laboratory, which has been monitoring the weather on Long Island since 1947.

The mercury reached 88.7 degrees at the Upton lab Wednesday, falling far short of the daily record of 96 degrees set in 1983.

A cold front is expected to bring scattered showers and thunderstorms in the afternoon and evening Thursday, opening the door to a more seasonable air mass bringing temperatures in the 70s through the weekend.

While "certainly not rare for this time of year," Wednesday's hot weather is "more typical to occur in July into August," Morrin said.

The last time the thermometer reached 90 at the airport was on July 20, the final day of a heat wave that began July 14, he said.
