A severe thunderstorm watch for Long Island originally issued until 10 p.m. Tuesday has expired.
Storms did move through earlier Tuesday evening but conditions appeared quiet in most areas of Long Island by about 8:30 p.m.
As of 7:30 p.m, more than 3,600 PSEG Long Island customers were without power, the utility's website said, but that number declined to just over 800 by 8:45 p.m. Tuesday.
Tuesday's high hit 90 degrees across much of Long Island Tuesday, with humidity levels already pushing 80 percent in most areas and above that in some.
The weather service called for overnight lows into the upper 60s and a high of just 78 degrees expected Wednesday.
However, the strong possibility of thunderstorms is forecast for later in the week as well, starting Thursday and running through Saturday.
