STORM WATCH: SHOWERS TONIGHT, ROUNDS OF RAIN FRIDAY

Periods of moderate to heavy rain are still on the way to Long Island into Friday! This evening will still be drier than wet, but keep the rain jacket and umbrella with you. There will still be some widely scattered showers from time to time paired with a southwest breeze with gusts up to around 20 to 25 mph. That wind will subside overnight. It will stay mostly cloudy and mild with those occasional showers through the evening. Temperatures will remain in the 60s.

Scattered downpours can start to arrive any time after 10 p.m. tonight. This will set the stage for a wet Friday, but there will be a wide range of rain totals across Long Island and some breaks in the rain at times. Budget a little extra travel time and keep the rain gear with you all day.

The steadiest and most widespread rain is likely in the morning through early afternoon with a few rumbles of thunder. While there will be breaks in the rain at times in the afternoon and evening, there will still be some rounds of rain moving through. By afternoon and evening, the best chance for steadier and heavier rain will be over central and eastern Suffolk County. It will be drier for Nassau and northwestern Suffolk Counties by that time with just some scattered showers. Rain totals will be around 0.5" to 1.5" in Nassau and northwestern Suffolk Counties, but can be as high as around 2" to 4" of rain in central and eastern Suffolk County. The last of any steadier rain will taper off in eastern Suffolk County around or before midnight. Stay with News 12 for updates all day on Friday.

TRAVEL IMPACTS: Wet leaves can make travel more slippery this time of year and those leaves can clog storm drains and lead to some ponding of water and minor street flooding. Keep this in mind and use caution traveling on Friday. Areas that see more downpours - especially eastern Suffolk County - have the best chance to see more scattered areas of minor flooding. Use caution traveling all day.
