Long Island weather: Dense fog, possible storms overnight

The National Weather Service has issued a dense fog advisory for parts of Long Island Wednesday night into early Thursday morning.

In an advisory issued just after 9 p.m., the service warned drivers to watch out for dense fog in northwestern and northeastern Suffolk, southwestern and southeastern Suffolk, and northern and southern Nassau.

The advisory is in effect until 4 a.m. Thursday.

Visibility could be just a quarter-mile or less at times, the service said, especially along the coast.

Faye Barthold, National Weather Service meteorologist based in Upton, said the best chance for precipitation is from around 8 p.m. Wednesday to midnight.

Locations most likely to see overnight thunderstorms are to the north and west of New York City, she said, though a rumble of thunder can’t be ruled out for Long Island.

Thursday will bring a day that so far appears to be rainfree, with mostly sunny skies and temperatures rising to around 79 degrees, which would be a couple of degrees above normal, she said.

Friday will see mostly sunny skies, at least until around noontime, after which comes a 30 percent chance for showers and thunderstorms, the weather service said.

The weekend looks like a mixed bag, with the forecast calling for a mostly sunny Saturday and a 50 percent chance of showers Sunday.
