Watch out for a few scattered showers tonight as a cold front slides through the area. Any rain that falls tonight will be on the light side, with totals of a quarter inch or less expected across Long Island.

Cooler and drier air will move in behind the cold front. The air will become noticeably less humid throughout the day on Friday, with dew points dropping from the 60s into the 50s and possibly the 40s by Friday night.

Saturday afternoon will stay fairly cool, with temperatures in some areas struggling to reach the upper 60s. Saturday night, a warm front will move in, bringing more clouds and an increasing chance of rain. Rain is likely by Sunday morning and could continue through much of Sunday before gradually ending Sunday night. At this point, some flooding could be possible throughout the day.

The first day of fall is Tuesday and overall, temperatures should be slightly cooler than normal through midweek, especially during the daytime, because of winds coming from the northeast and east.
