Guidance shows the activity weakening overall, but we still anticipate some snow squalls/snow showers as the front passes through, some of which could coat the ground in places. #NJ #NJWX #WX #Weather

New Year's Eve will become mostly cloudy with a chance of snow showers. Snow showers or even a snow squall is possible in the morning on New Year's Day, followed by bitter cold. Temperatures will fall back some after the daybreak frontal passage and stay in the 20s for most. #NJ #NJWX #WX #Weather

There is a lot of dry air in place, so it will be tough to overcome, but we'll put the chance at 20-30 percent of some flakes reaching the surface. #NJ #NJWX #WX #Weather

A couple of our new high-resolution computer model runs are showing a weak impulse could yield a couple snow showers overnight across the area. Given how cold it is, if snow reaches the ground, dustings or coatings would be possible. #NJ #NJWX #WX #Weather

The ocean-effect snowband is starting to diminish some, but it’s put down a fresh coating or more of snow for many. #NJ #NJWX #WX #Weather

Another ocean-effect snow band has developed. Much like lake-effect snow, these can cause localized winter weather conditions and snow accumulations of a coating-inch over a narrow corridor where it trains. #NJ #NJWX #Weather #WX

Our next weather maker will be a warm front that pushes through Sunday afternoon and evening.

Temperatures may be hovering around freezing in Northwestern NJ, and this could lead to a period of freezing rain. Guidance is in fairly good agreement with a swath of light icing.
