A second day of record-breaking temperatures is expected for Wednesday on Long Island when it will feel like “summertime” in some areas, the mercury possibly hovering around 70 degrees, according to forecasters.

Morning clouds, drizzle and fog will open Wednesday as was the case on Tuesday when record highs were set at Islip and LaGuardia and Kennedy airports. But it is predicted to become partly sunny and warm, setting the stage for temperatures to rise almost 30 degrees above normal.

According to Joe Pollina, a meteorologist with the National Weather Service at Upton, Tuesday broke “quite a few records” in the Long Island area and on Wednesday “it’s going to be even warmer.”

“There’s kind of a summertime high pressure over the western Atlantic setting up a southwesterly flow bringing in a Bermuda high that brings in heat and humidity in the summer,” Pollina explained.

Pollina said that by 1:54 p.m. Tuesday a new record of 64 degrees was set for the high at Islip — topping the former record of 62 set for the date in 2016. Also Tuesday afternoon Kennedy reached a high of 64, breaking the record of 61 set in 1949 but the real record smasher was LaGuardia where the temperature climbed to 68, leaving behind the record of 63 set in 1943.

The normal high and low for both Tuesday and Wednesday at Islip is 41 and 26 respectively, according to the Weather Service.

Nassau is expected to have highs in the mid-60s on Wednesday with New York City predicted to possibly reach 70 while the Twin Forks will be cooler and remain in the 50s, Pollina said. He added the record high for Wednesday’s date was 63 set in 2002 and the forecast calls for a high of at least 64.

“Remember water temperatures range from 38 to 42 degrees, so that tends to keep Long Island cooler,” said News 12 Long Island meteorologist Bill Korbel.

Pollina said the record for Wednesday’s date at La Guardia was a high of 68 set in 1958 and he said the same high of 68 is predicted again for Wednesday. This time he said JFK could be the big record smasher with a high of 69 being expected compared to the previous record high of 63 set in 2002.

Korbel said Wednesday night will be mostly cloudy with a chance of showers and lows near 46 ahead of a mostly cloudy Thursday with scattered showers and the high going back down to a more seasonable 46 degrees with an overnight low of 35.
