Heat advisory in effect through Monday

The National Weather Service is forecasting heat indexes of up to 102 degrees the next two days on Long Island, with some relief expected later in the week.

The weather service issued a heat advisory for the entire Island for Sunday through 8 pm Monday, with heat indexes of 95 to 100 degrees for most of the Island on Sunday, and up to 102 degrees on Monday. Heat indexes will be up to 97 degrees in eastern Suffolk County. Heat indexes are “feels-like” temperatures that take into account the humidity.

Air temperatures Sunday will range from the lower 90s in parts of Nassau to the upper 80s in eastern Suffolk, with winds of up to 15 mph in the afternoon, said weather service meteorologist Nelson Vaz.

Look for similar temperatures on Monday and Tuesday, he said.

There also will be a 20% chance of isolated thunderstorms the next few days, especially in the afternoon, he said.

“We’re just in a very hot and humid pattern, and that’s really the fuel for these thunderstorms,” ​​Vaz said. “Where you’ll have the better chance of seeing it is closer to the city, where you’ll have more heat and humidity to deal with.”

But, he said, “Most locations will see nothing.”

Nighttime temperatures Sunday through Tuesday will be in the lower and mid 70s.

“The next chance for some type of change is Wednesday,” Vaz said. “That may be our next chance of seeing more widespread shower and thunderstorm activity.”

The chance of rain Wednesday is 60%, with highs forecast in the mid 80s.

There’s a 30% to 40% chance of rain Thursday and Friday, with temperatures in the lower or mid 80s.
