Summer’s first heat wave — defined as three consecutive days of temperatures above 90 degrees — is forecast to bring sweltering conditions to Long Island this weekend.

The National Weather Service (NWS) predicted temperatures will hit about 90 on Friday, 95 on Saturday, and 97 on Sunday. NWS issued an excessive heat warning for Nassau and Suffolk counties from 6 a.m. Saturday through 8 p.m. Saturday and a heat advisory from noon Friday to 6 a.m. Saturday. Heat index values will make it feel as hot as 106 during the peak of the heat wave, forecasters say.

“Extreme heat can cause illness and death among at-risk population who cannot stay cool,” Upton-based NWS meteorologists said in the heat warning. “The excessive heat may
quickly cause heat stress or heat stroke
.”

NWS also issued an air quality alert for LI and the tri-state area through 11 p.m. Friday, due to elevated air pollution levels that can cause health concerns.

Temps are expected to cool off again Monday into the 80s when storms are forecast to possibly hit the area.
