NEW YORK — A powerful summer storm moved into the region Monday, fed by high temperatures and high humidity that made for another dangerously hot day.

A severe thunderstorm warning was issued for for Kings, Queens, Bronx and Nassau counties, according to the National Weather Service.

An earlier warning applied to central Passaic and Bergen counties in New Jersey; Fairfield, Middlesex and New Haven counties in Connecticut; and central Westchester County in New York, according to the National Weather Service. It expired at 4:15 p.m.

Large hail, damaging winds and lightning are all occurring with this system. Gusts from the storm could reach 60 mph, and damage to roofs, siding and trees are possible, the agency said.

The rest of the region remained under a severe thunderstorm watch until Monday evening, the NWS said.

That alert applies to Bergen, Passaic, Essex, Union and Hudson counties; and Bronx, Kings, Nassau, New York (Manhattan), Orange, Putnam, Queens, Richmond (Staten Island), Rockland and Westchester counties in New York; Middlesex, New Haven and New London counties in Connecticut.

Extreme heat is powering the storms, which won’t bring relief from the sweltering temperatures.

A heat advisory issued over the weekend has been extended through at least 8 p.m. Tuesady for the five boroughs, where temperatures climbed into the mid 90s to start the week.

The high in Central Park reached 93 degrees Monday, 4 degrees short of the record high temperature for July 25 set in 1999, according to the National Weather Service.

This heat wave is forecast to last through Thursday, when the mercury is expected to slide backwards into the 80s.
