STORM WATCH: SCATTERED RAIN, BREEZY ON FRIDAY

It is dry with gradually increasing clouds this evening after a spectacular Thursday, but you will need the rain gear at times on Friday. It will not be raining all day on Friday, but there will be the chance for scattered rain and even an evening strong thunderstorm that can briefly slow down your travels.

Overnight, it will be mostly cloudy with scattered showers arriving after midnight. Off and on rain showers will continue through Friday morning with dry breaks at times. Most of the morning showers will be light to moderate, but a brief downpour cannot be ruled out.

There will be several hours of nice weather in the afternoon! Breaks of sun with temperatures in the upper 60s to lower 70s are expected in the early to late afternoon. So, there will be some time to enjoy outdoors if you would like to.

After 7 p.m., a broken line of thunderstorms will be approaching Long Island from the west. There is a chance, especially in Nassau County, for a briefly strong to severe thunderstorm with wind gusts between 40 and 60 mph. News 12 will keep you updated on this through Friday on-air, on social media and the News 12 app.

After that brief thunderstorm chance between around 7 p.m. and 10 p.m., scattered periods of rain showers will persist Friday night, ending before 8 a.m. Saturday. Just use caution traveling as you can briefly encounter lower visibility and gusty wind during the rain.

It will feel like the upper 30s in the morning with wind gusts between 20 and 35 mph. Highs will only reach the lower 50s in the afternoon and while the wind will start to subside a little, it will still feel chilly.
