For tonight, expect partly cloudy skies with dry and comfortable conditions. Temperatures will cool into the 50s overnight. Heading into Tuesday, we'll see a mixture of sunshine and clouds throughout the day. It will be a little cooler, with afternoon highs generally in the 60s to near 70 degrees. Clouds will increase Tuesday night, bringing a slight chance of a passing shower, although most locations should remain dry.

Wednesday is shaping up to be the warmest day of the week. We'll enjoy plenty of sunshine mixed with a few clouds, and temperatures will climb into the mid- and upper 70s. That's well above average for the middle of October and will make it feel more like late September. If you have outdoor plans, Wednesday looks like one of the nicest days of the week before cooler weather returns.

Changes arrive Thursday as temperatures drop back into the 60s despite a good deal of sunshine. It will still be a pleasant fall day, just noticeably cooler than Wednesday. Clouds will begin increasing Thursday night as our next weather system approaches the region. That will set the stage for an unsettled finish to the workweek.

Friday looks to bring cloudy skies and periods of rain across Long Island, with temperatures generally in the 60s. Behind this system, colder air will move into the region as we head into the weekend. While the timing of the rain still needs to be fine-tuned, the overall trend points toward a return to more typical October weather, possibly even a little colder. After our midweek taste of warmth, you'll want those jackets and sweatshirts handy again for the weekend. As of right now, most of the weekend looks dry and we could end our wet Sunday streak. Lows over the weekend will be in the 30s and low 40s and highs in the 50s.
