The bad news: New Jersey is getting a wintry blast of snow and cold temperatures coming off the long Thanksgiving weekend.

Sunday saw the arrival of icy conditions and some snow in the northern part of the state, while much of the rest of NJ dealt with rain or sleet, according to NJ 101.5 Chief Meteorologist Dan Zarrow.

The biggest snow accumulations are yet to come Monday, as this storm system strengthens dramatically just off the coast, Zarrow said.

A Winter Storm Warning continued Sunday evening for western Bergen, Morris, Passaic Sussex, and Warren counties, while also including Hunterdon, Mercer, and Somerset counties.

A less-urgent, less-severe Winter Weather Advisory was in place for eastern Bergen, Essex, Middlesex, and Union counties. That also was expanded by Sunday evening to include Burlington, Camden, Gloucester, Hudson, Monmouth, and Ocean counties.

A Coastal Flood Advisory was in effect for Middlesex, Monmouth, and Ocean counties, where a foot of surge may cause minor flooding during Monday's midday high tide cycle.

Monday was looking snowier than originally anticipated, Zarrow said, with a possibility for isolated double-digit totals in North Jersey and some late Monday snow accumulation in South Jersey. Zarrow said by the time this storm winds down, it appears snow accumulation is possible anywhere in New Jersey by Tuesday morning.
