THIS EVENING AND OVERNIGHT

After another nice fall day with more of a mix of sun and clouds and seasonal temperatures, clouds will slowly clear more this evening. It will become partly cloudy overnight. Temperatures are dropping through the 50s and into the 40s this evening. Have a coat with you through the overnight. Low temperatures into Thursday morning will be in the mid-to-upper 40s under a partly cloudy sky.

DRY STREAK CONTINUES

We are past 10 days and counting since measurable rain here on Long Island. Check out some rain statistics for the month below. As of now, a couple of showers will be possible next Tuesday and Wednesday, but the next best chance for any sort of steadier rain may hold off until next Thursday or Friday.

HALLOWEEN FORECAST

The forecast for Halloween on Saturday is still looking pretty nice for all the trick-or-treaters and Halloween festivities. We're expecting sunshine during the morning, with a few clouds in the afternoon. Temperatures will be cooler compared to Friday, with highs in the upper 50s and lower 60s. 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.
