Long Island weather: Cooler, less humid and feeling like fall

Long Island will see a dip in temperatures during the day Friday and Saturday, down to what’s more seasonable for October, with a rebound to above normal starting Sunday, forecasters said.

It will be "a taste of fall today and Saturday," News 12 Long Island meteorologist Rich Hoffman said. Indeed, look for “cooler and noticeably less humid conditions” Friday and Saturday, the National Weather Service predicted.

Friday was expected to bring partly sunny skies, with the day warming up to the mid-60s, the weather service said.

"A little bit of a chill out there this morning," Hoffman said. "Air is much drier."

High tide time Friday evening brings isolated minor coastal flooding to Nassau County’s southern shoreline, the weather service said. There is a small craft advisory off the South Shore until 6 p.m. Saturday.

Conditions cool down overnight to the low to mid-50s by early morning Saturday, which is forecast to see mostly sunny skies.

Normal daily highs at Long Island MacArthur Airport in Ronkonkoma are 66 to 67 degrees, with 49 normal for overnight lows.

Then a warmup comes during the day Sunday and Monday, Columbus Day, with temperatures heading up to the mid- then low 70s, the weather service said, with both featuring sun and clouds.

While the bulk of Long Island trees normally see peak leaf color toward the end of the month and into early November, other areas of the state have started the annual transition to autumn hues.

Vibrant peak and near-peak colors are expected this weekend in some spots of the Adirondacks, according to the weekly fall foliage report issued by

Most of the state’s northern areas will be midpoint in the transformation process, with southern areas just starting it, leaf spotters reported. Long Island and New York City are the only holdouts at this point, with no significant change at all.
