A heat advisory on parts of Long Island will last through Tuesday evening, according to the National Weather Service.

The advisory covers parts of New Jersey, Connecticut and New York. On Long Island, the advisory is issued for Northern Nassau and Northwest Suffolk counties, lasting through 8 p.m. Tuesday, according to the National Weather Service website.

“Pretty much anywhere north of the LIE in the western part of Suffolk would be fair game,” said David Stark, a meteorologist at the National Weather Service, noting that the sea breeze takes longer to reach this area.

Stark said temperatures in Northern Nassau and Northwest Suffolk were in the low 90s Monday, but combined with humidity it felt like the upper 90s. Temperatures were slightly lower elsewhere on the Island. Similar conditions were predicted for Long Island Tuesday. 

There are also increasing chances for showers and isolated thunderstorms developing Tuesday, Wednesday and Thursday, the weather service said. But the higher risk for storms is in New York City and northwest of Long island.

Tuesday is expected to reach 83 degrees, and Wednesday’s high could reach 84, along with high humidity, according to a detailed forecast from the National Weather Service.

Stark says the heat is seasonal. “While it is hot, it is nothing too unusual for this part of the country this time of year,” he said.

The record highs from Islip for these next three days took place in 1993 when July 8 reached 94 degrees, the 9th hit 95, and the 10th saw a 98 degree high. That was a proper heat wave, meteorologists said.

Stark does not anticipate a heat wave this week on the Island, which would require three consecutive days over 90 degrees. “We are not predicting anything warmer than we have today for the rest of the week,” he said.

Gov. Kathy Hochul sent out a release about potential impact from the heat, saying: “Keep an eye on your local forecast, stay hydrated and postpone outdoor activity if possible.”
