Long Islanders should brace for a hazardous commute Friday morning, when the heaviest of the day’s snowfall is most likely to occur, according to the National Weather Service.

A storm system was to sweep in to the area overnight, starting as rain and switching to snow in the early morning hours, forecasters said.

Earlier morning commuters may face minor accumulations, possibly of around an inch, said Peter Wichrowski, National Weather Service meteorologist in Upton. Those heading to work later, say around 9 a.m., could see “a good, steady snow,” that could be moderate, even potentially heavy if a band sets up.

Expect “a messy commute Islandwide,” said News 12 Long Island meteorologist Bill Korbel, with the weather service, warning of slippery travel.

A winter storm warning was issued for eastern Suffolk County — that’s east of the William Floyd Parkway — through late afternoon, with a winter weather advisory in effect through 2 p.m. for the rest of the Island.

Snowfall could amount to around 3 to 6 inches for the Island, with those higher figures as you head east, Wichrowski said. Any bands of heavy snow would raise those amounts.

Snow wraps up in the afternoon, but there’s also potential for some snow showers late afternoon into evening — brief but possibly heavy — as an Arctic front moves in, bringing much colder air for the weekend.

Overnight lows Friday are in the mid-teens, with wind chill early Saturday in the single digits to around zero, the weather service said. Look for cold conditions to continue into next week.
