Turning Attention to Part 2

Part one of the storms did not live up to the forecast as the snow and sleet was minimal in Central and Southern New Jersey. Many picked up a coating of snow which was followed by light freezing rain and freezing drizzle. The light icing made for a difficult morning commute.

Temperatures are now rising above freezing in most of the area. The big question tonight will be which locations will drop a few degrees with the diminishing daylight. For some areas, this could be extremely close as 32/33 degrees makes all the difference between an ice storm and a heavy rain storm. The high resolution models continue to indicate icing north of the Atlantic City Expressway and west of the Garden State Parkway. More serious icing continues to appear as though it will affect Northwestern Central New Jersey into Northern New Jersey.

The warm air aloft has even begun to impact the northern counties so it looks as though the snow will even be minimal there. Sussex County has temperatures in the teens, so some snow could still be falling in that county. Should there be rain, it will be quite dangerous up there.

A winter storm warning has been continued for Sussex, Hunterdon, Somerset, Warren, Morris, Mercer, Middlesex, Passaic, Essex, Union, Hudson, and Bergen Counties. This is for both part one and part two of the storm.

A winter storm watch has been continued for Burlington, Camden, Gloucester, Salem, Ocean, and Monmouth Counties. This is for part two of the storm only.

A winter weather advisory has been continued for Atlantic, Burlington, Camden, Gloucester, Salem, Ocean, and Cumberland Counties. This is for part one of the storm only.

Criterion:

A winter storm warning means four inches or more of snow or sleet and/or 0.25” or greater of ice accretion is imminent or occurring. North of Interstate 195, the criteria for snow is six inches.

A winter storm watch means four inches or more of snow or sleet and/or 0.25” or greater of ice accretion is possible. North of Interstate 195, the criteria for snow is six inches.

A winter weather advisory means two inches of snow or sleet/and or 0.01” to 0.24” of ice accretion is imminent or occurring. North of Interstate 195, the criteria for snow is three inches.
