A week of mostly sub-freezing temperatures is expected, with Tuesday having the best shot to push briefly above the freezing mark south. A weak clipper will bring a light snowfall to southern areas Tuesday night into early Wednesday. #NJ #NJWX #WX #Weather

Some climate sites in the week ahead could challenge records for longest sub-freezing stretch, though the new week will be more tolerable than it has been. The weekend, however, will still have nasty wind chills. #NJ #NJWX #WX #Weather

Virtually all 00z guidance has no snowfall this weekend, with an offshore low a swing and a miss. There is still one or two models that show a graze with some snow showers at the beaches. We'll still be watching it given how close some guidance shows the shield. #NJ #NJWX #WX #Weather

GFS and Canadian represent a scenario where this storm can get pulled closer to the Mid Atlantic, and clip the coastal plain of NJ, so that possibility is still on the table, as well as a possibility of a complete miss as represented by other models. #NJ #NJWX #WX #Weather
