A nice mixture of sun and clouds with another warm day across Long Island. High temperatures will reach the 80s for most areas, while the immediate shoreline stays a little cooler with temperatures in the 70s.

Long Island Rip Currents

Tonight, the sun goes down just after 7 p.m. Skies will become increasingly cloudy as temperatures fall into the upper 60s and lower 70s. Most of the night will be dry, but the chance for showers increases toward daybreak, so you may want to have the umbrella ready when you wake up Thursday morning.

Thursday starts with the chance for a few showers before we see some breaks of sunshine during the day. It will be warm and humid, with highs climbing into the 80s. Another round of spotty showers will be possible during the afternoon and evening. A few showers could linger Thursday night into very early Friday morning before we start drying things out.
