Scattered showers move from west to east across Long Island this evening as a cold front crosses the area. An isolated thunderstorm is possible, and a few showers could briefly produce a heavier downpour. Rain gradually tapers off from west to east overnight, followed by falling temperatures and a shift to a cooler northwest breeze.

A noticeable change. Mostly sunny, breezy and much cooler with lower humidity. Temperatures will be roughly 10 to 15 degrees cooler than Friday in some locations, making it feel much more like October. North winds around 10 mph will add to the cooler feel.

Mostly clear to partly cloudy and chilly with light winds. Temperatures fall well into the 50s across Long Island.

Some sunshine is possible early, but clouds will steadily increase as an area of low pressure approaches from the south. Showers may begin developing during the afternoon, especially after about 2 p.m. and particularly across coastal portions of the Island.

Cloudy with periods of showers possible. Current indications suggest rainfall will generally be light, and significant impacts are not expected. There is still some uncertainty concerning how closely the developing wave of low pressure passes to Long Island.

Any lingering clouds or early showers give way to increasing sunshine. A reinforcing cold front moves through later in the day, opening the door for a much colder air mass Monday night.

Mostly clear, breezy and considerably colder. Temperatures fall into the 40s across much of Long Island as Canadian high pressure begins building into the region.

Sunny, breezy and quite cool. This will likely be the coolest daytime air of the season so far, with afternoon temperatures struggling to reach 60 degrees in many locations—around 10 degrees below normal.

Another sunny, crisp fall day with very low humidity and temperatures remaining well below normal.
