Slippery roads and walkways are predicted for Thursday morning, with temperatures dropping and turning overnight rain into a light snowfall, the National Weather Service said.

With a low of freezing and gusty winds continuing into Wednesday night, a wintry mix and then snow will begin to fall on Long Island in predawn hours Thursday, accumulating about a half-inch by morning, the weather service said, and continuing throughout the first half of the day.

"A quick moving system is expected to bring a period of light rain overnight changing to light snow early Thursday, impacting the Thursday morning commute with slippery road conditions," the weather service said in a Wednesday night advisory.

"Snow is expected to end Thursday afternoon from west to east. A widespread 1 to 2 inches of snow is expected with locally up to 3 inches of snow."

There is a winter weather advisory for the region from 5 a.m. Thursday to 1 p.m.

Unlike the past few rounds of snow, the very cold Friday and weekend temperatures will make it less likely that it will swiftly melt away.

Wind chills Thursday will be between 20 and 30 degrees, and the low Thursday night won't be more than 13 degrees.

Friday will be partly sunny; with the high topping out at just 24 degrees with a north wind of about 13 mph and a nightime low of 16, forecasters said, with wind chills well below zero.

There is a 30% chance of snow Friday night with the same odds of more coming early Saturday.

The daytime high Saturday will be just 27 degrees and a low of 18 degrees with cloudy skies.

On Sunday, temperatures should rise just above freezing, hitting 34 under partly sunny skies. The nighttime low sinks to 19.
