Light snow expected overnight on Long Island

More light snow is expected for Long Island, thanks to a clipper-like system sweeping in over the Great Lakes, the National Weather Service said Monday.

Less than an inch of snow is likely early Tuesday for most portions of Nassau and Suffolk counties, said Brian Ciemnecki, a meteorologist with the Upton-based service.

Chance of precipitation overnight into Tuesday is 50 percent and again overnight into Wednesday is between 30 percent and 40 percent, the service said.

"Nothing major," Ciemnecki said. "It's going to be cold, so we'll have fluffy snow that will easily blow around. Less than an inch to less than a half-inch in some spots."

The snow could make for a slightly slower morning commute, Ciemnecki said.

Traditionally, an Alberta clipper is a low-pressure system that moves east over the Great Lakes and through the Midwest, depositing in its path at least a couple of inches of snow and often colder temperatures.

"This maybe isn't a true Alberta clipper, because it's not bringing much snow," Ciemnecki said, "but it will be cold."

Temperatures will range from the mid 20s to the low 30s until Wednesday, the service said.

Mostly, the system will bring snow west and south of Long Island, the service said, with portions of Michigan, Wisconsin, Illinois, eastern Pennsylvania and some mid-Atlantic states getting up to 3 inches.
