***BLIZZARD WATCH FOR SUFFOLK COUNTY AND PARTS OF CONNECTICUT***

The computer models continue to show a major snowstorm for many parts of the tri-state area.  Confidence continues to grow and the computer models are even more ominous. 

Both GFS and the European have bombogensis occurring at the benchmark of 40N 70W, with an intense deformation zone setting up over much of the tri-state area (2maps below)  This is when our heavy snow will fall and rapid accumulation will occur.  Another note, the storm will be a slow mover Friday Night; it may stall or do a loop Southeast of Nantucket.  This will SHOULD prolong the accumulating snow in our area.

High winds between 50-60mph are possible along the coast along with coastal flooding. 

A bit of snow will break out later tonight through tomorrow morning, could coat the ground in many areas.  Then as warm air works in a mix and rain is likely, especially closer t the City and coast. Once the strengthening upper level storm reaches the area cold air will rush in and change the precipitation to snow from Northwest to Southeast.

The brunt of the heavy snow will fall from Friday Evening Through 6am Saturday. 

Again, this is not etched in stone, but I CANNOT ignore the continuous model to model consistency.  As I always state, the snow amount graphics are just a possibility and will be adjusted as we approach the event. 

An incredibly dynamic situation, reminiscent of the Blizzard of 5-7 1978.

Stay Tuned.
