After a mostly cloudy day in the 50s Wednesday, that night will bring a slow-moving storm system that carries with it the potential for heavy rain and strong winds, the National Weather Service said Tuesday.
The weather service said up to 1.5 inches of rain could fall on Long island from late Wednesday through Friday morning.
"The slow movement of the front may result in training of showers, which has the potential to bring locally higher amounts which raises the concerns for at least minor flooding," the service said in a storm briefing Tuesday afternoon.
"Southeasterly winds will increase on Wednesday afternoon and continue into Friday. The strongest winds will accompany the cold front Thursday into Thursday night when wind gusts could range from 30 to 40 mph, especially near the coast," the briefing said.
Saturday and Sunday should be at least partly sunny, with highs in the 60s.
Rain may return Monday, the weather service said. A high near 60 degrees is predicted.
