Long Islanders can expect a rainy and foggy Saturday afternoon, though drier skies are forecast for Sunday.

Areas of "locally dense fog are expected to develop across the region this afternoon and into early this evening," the National Weather Service said in a special weather statement issued for Saturday afternoon.

Motorists are advised to slow down as visibilities of less than a quarter-mile can be expected, the service said in a special weather statement. Visibilities are expected to improve later Saturday evening.

Rain will continue to fall throughout the day, likely tapering off in the late afternoon and early evening, said Joe Pollina, a meteorologist in the service's Upton office. There is a 30 to 40 percent chance of rain from 8 p.m. Saturday through midnight, he said.

In total, the region should get about an inch of rain.

Minor flooding was reported on the Northern State Parkway near Exit 41, according to State Police.

"There may be big puddles on the road but flooding won't be too much of an issue," said News 12 Long Island meteorologist Samantha Augeri. "Of course it makes it rough to drive around with all the potholes."

Temperatures Saturday are expected to reach the upper 40s and drop into the mid-to-upper 30s overnight.

Sunday's forecast calls for temperatures in the mid-to-upper 40s. There is a chance of rain Sunday on the East End in Suffolk, but the rest of Long Island should remain dry, Pollina said.
