Mostly Sunny skies with some passing clouds. Highs 62 to 68. It will be a little breezy at times, but overall, it's shaping up to be a very nice fall day. Whether you're heading out for a walk, getting some outdoor work done or enjoying the beautiful fall foliage, the weather is certainly cooperating.

Tonight, we'll see partly cloudy skies with temperatures dropping into the 50s for most of Long Island. Some of our colder spots, especially around the Pine Barrens, could dip into the 40s, so you'll want a light jacket if you're heading out early Friday morning.

Friday is looking fantastic as we wrap up the workweek! We're expecting mostly sunny skies with temperatures reaching the upper 60s to lower 70s. That's pretty mild for the end of October, so take advantage of the warmer weather while it lasts. A cold front will move across Long Island Friday night, bringing a return to cooler temperatures just in time for Halloween. Skies will clear out, and overnight lows will drop into the 40s, setting us up for a chilly start to Saturday morning. The good news is that we're not expecting any rain with this front, so outdoor plans are looking good heading into the weekend.

Happy Halloween! Saturday is shaping up to be a nice day for all your Halloween activities, with dry weather expected throughout the day. We'll see a mixture of sunshine and clouds, with afternoon temperatures generally in the 50s, possibly reaching close to 60 degrees. For all the little ghosts and goblins heading out trick-or-treating Saturday evening, the forecast is looking pretty good! Expect some clouds around, but no rain, with temperatures in the lower 50s during the early evening before gradually cooling into the 40s later at night. A light jacket or an extra layer underneath those Halloween costumes might be a good idea. Sunset Saturday will be shortly before 6 p.m., so make sure the kids have reflective clothing, glow sticks or flashlights to help drivers see them. Drivers should also slow down and use extra caution in neighborhoods with trick-or-treaters.

Don't forget, daylight saving time comes to an end early Sunday morning! We'll turn our clocks back one hour at 2 a.m., giving us an extra hour of sleep. It's also a great time for an important home safety reminder. Test all your smoke alarms and carbon monoxide detectors, replace batteries if needed and check the expiration dates on your detectors. Smoke alarms generally should be replaced every 10 years, while carbon monoxide detectors should be replaced according to the manufacturer's instructions. It's also a good time to check your fire extinguishers, review your family's fire escape plan, make sure your heating system is ready for the colder weather and check your outdoor lighting and timers. With the time change, sunset Sunday will be shortly before 5 p.m., meaning it will get dark much earlier during the evening commute and after-school activities. As for Sunday's weather, we'll start off chilly with temperatures in the 40s, followed by mostly sunny skies, a few passing clouds and afternoon highs climbing back into the 60s.

Overall, we're looking at a really nice stretch of fall weather across Long Island as we head into the Halloween weekend. Friday will be our warmest day, followed by a cooler but dry Halloween on Saturday and a pleasant rebound in temperatures on Sunday. It's great weather for trick-or-treating, youth sporting events, fall festivals, pumpkin picking, enjoying the beautiful fall foliage or getting some last-minute outdoor projects done before November arrives. Just keep a sweater or light jacket handy for those chilly mornings and evenings. And remember, as we turn the clocks back this weekend, take a few minutes to make sure your home and family are ready for the colder months ahead. Enjoy the beautiful fall weather, have a safe and happy Halloween, and don't forget to turn those clocks back Saturday night!

Dry conditions will continue for all those outdoor Halloween activities. During the evening trick-or-treating hours, temperatures will be in the 50s, making for some nice and comfortable weather for the kids heading out to collect their candy. Saturday night will be partly cloudy, with overnight lows dropping into the 40s.

CLOCKS 'FALL BACK' THIS WEEKEND

Daylight saving time ends early Sunday at 2 a.m., so don't forget to turn your clocks back one hour before heading to bed Saturday night. You'll get that extra hour of sleep, but sunset will arrive about an hour earlier Sunday evening. It's also a great time to check your smoke detectors and carbon monoxide detectors, replace batteries if needed, and make sure everything is working properly as we head into the colder months ahead.
