Surprise ! Cold weather couldn't settle too long without a snowstorm !
As the arctic air went more South than forecasted, it appears that as a reaction, some warm sub tropical air will move north along the US East shore.
Models are still hesitant whether the storm will hit NYC/NJ
However, a trend has shown up in the last 3 GFS Model updates (American Model) showing the storm less and less offshore and bringing more and more snow each update
1/2/18 12:00 Z update (Parsippany: ~1in / NYC: 1 to 3in)
1/2/18 18:00 Z update (Parsippany: 1 to 2in / NYC: 3 to 5in)
1/3/18 00:00 Z update (Parsippany: 3 to 4in / NYC: 3 to 4in)
Personal forecast :
- Assuming the storm path continues to move slightly more inland (Parsippany: 3 to 5in / NYC: 4 to 8in)
