Whether the heat wave sizzles its way into Day 5 remains to be seen. The National Weather Service said in some places it will and in some places it won't. But no matter where you live in metropolitan area, this is it.
Relief comes Friday.
Forecasters said that after four straight days of 90-degree-plus heat - including three days of record-breaking temperatures at Long Island MacArthur Airport in Ronkonkoma and back-to-back days of 100-degree-plus heat recorded in Central Park and Kennedy and LaGuardia airports - the heat wave is "winding down."
Temperatures are expected to drop into the low 70s Thursday night, a welcome relief.
"After an uncomfortable night, an onshore flow of air will keep temperatures closer to normal mid-July levels," the weather service said in a statement. "High temperatures should be about 10 degrees" than they were Wednesday.
The break in the weather is because of an approaching cold front that forecasters predict will bring showers and thunderstorms for the next few days.
Rain Saturday is expected to be particularly heavy - and could produce "urban, poor-drainage and small-stream flooding," forecasters warn.
But the cold front should cool things down fast.
Though New York City could still hit at least 90 degrees for the fifth straight day, in most places in Nassau and Suffolk, the mercury will only soar into the upper 80s - marking an official end to the heat wave at four straight days.
Islip has recorded temperatures of 97 degrees, 95, 101 and 96 so far this week.
It's been 96, 99, 103 and 100 in Central Park; 101, 97, 101 and 100 at Kennedy; and 98, 99, 103 and 101 at LaGuardia, according to the weather service.
The East End has been cooler, but not by much. The temperatures so far this week at Montauk have been 88, 91, 96 and 87.
It certainly beat being in Newark, N.J., which recorded consecutive days of 101, 102, 103 and 101. That's a scorcher.
