Wednesday afternoon was shaping up to be cloudy and breezy, with a slight chance of showers, just 20 percent, forecasters said.
But keep the umbrellas handy as the chance rises to 70 percent for Wednesday night, with rain most likely from 8 p.m. to 2 a.m., the National Weather Service said.
Nassau and Suffolk counties can expect daily highs in the low 40s and an east wind of between 18 and 21 mph, the service's Upton office said. With highs likely running 10 to 15 degrees below normal, "it will be a raw day," the service said in its forecast update.See alsoCurrent conditions
Wednesday night lows are expected to be in the mid 30s, said News 12 Long Island meteorologist Rich Hoffman.
There also is a chance for patchy fog overnight.
The stretch of cloudy, chilly weather with scattered showers and drizzle lingers until early Saturday, when clearing is expected, forecasters said.
In fact, on his Facebook page Hoffman said, "More #COLD weather today and you will need the umbrella. A beautiful weekend. We just have to get there."
