We're ending the workweek on a beautiful note across Long Island, with plenty of sunshine and comfortable fall temperatures. Most of Nassau and Suffolk counties will warm into the lower 70s this afternoon, while the immediate shoreline and East End will stay a little cooler, with highs in the 60s. It will become a bit breezy at times, with wind gusts around 20 mph. Overall, it's a fantastic Friday to get outside and enjoy some sunshine before changes arrive later this weekend. Whether you're heading out for a walk, enjoying some fall activities or just spending time outdoors, today's weather is looking great.
As we head into tonight, clouds will gradually increase, with skies becoming mostly cloudy across Long Island. It will turn chilly overnight, with temperatures dropping into the mid- and upper 40s. If you're heading out to a fall festival, haunted house or other outdoor event, you'll definitely want to bring along a jacket or sweatshirt. The good news is that we'll stay dry.
Saturday starts off on a nice note, with mostly sunny skies during the morning before clouds begin to build in the afternoon. Temperatures will be a few degrees cooler, with highs generally between 65 and 70 degrees. Overall, Saturday is looking like another good day for outdoor plans.
Saturday night, skies will turn cloudy, but we're expecting dry conditions to continue through the overnight hours. Temperatures won't be quite as chilly, with lows generally in the 50s. If you have Saturday evening plans, including any Halloween or fall festivities, the weather should cooperate. However, we'll be watching a developing weather system that will bring some changes for the second half of the weekend. Sunday morning looks mainly cloudy, but much of the morning should remain dry. By the afternoon, rain will begin developing across Long Island. It will also become a bit breezy, with afternoon temperatures generally in the 60s.
Sunday evening and Sunday night look to be the wettest part of the weekend. Expect cloudy skies with periods of rain, and there is even the possibility of a few thunderstorms. Some of the rain could become moderate to heavy at times, producing locally heavy downpours and reduced visibility on area roadways. While it doesn't look like a complete washout for the entire weekend, Sunday afternoon and especially Sunday night are the periods you'll want to keep an eye on. If you have outdoor plans Sunday, try to get them done during the morning before the steadier rain develops. Overnight temperatures will remain relatively mild, with lows in the 50s.
The unsettled weather will carry over into Monday morning, with cloudy skies and some lingering rain showers around for the morning commute. Keep the umbrella handy if you're heading out early. The good news is that improving weather is expected as we move through the afternoon, with showers gradually ending and drier conditions returning. We may even see a few breaks in the clouds later in the day. Afternoon temperatures will reach the upper 60s to around 70 degrees. The bottom line: Enjoy the sunshine and comfortable temperatures today, take advantage of another mainly dry day Saturday, and plan for wet weather Sunday afternoon through Sunday night. Better weather should return by Monday afternoon.
ISAIAS REMNANTS TO BRING RAINY END TO WEEKEND
Hurricane Isaias (ees-ah-EE-ahs), the first Atlantic hurricane of the 2026 season, is churning in the Gulf and expected to make landfall tonight. This storm is important to Long Island because the remnant moisture in the form of mostly light to moderate steady rain will reach the Island by Sunday afternoon through early Monday.
This storm will track inland from the Gulf and quickly weaken, but leftover rain from this will get pushed into the northeast and Long Island by late Sunday into Monday. This will not be a major storm by the time it reaches Long Island and some of the heaviest nearby rain is likely to stay south of Long Island.
Major impacts are not expected locally. However, it will be wet and breezy, with up to 1 inch of rain expected. So, there will be impacts to fall and weekend holiday festivities and travel plans late Sunday evening through Monday morning.
