Snows maps for Thurs/Fri:
Here are the new snow maps from the 12Z runs of the Euro, GFS, and Canadian models, respectively. The Canadian looks way overdone.
The 4th image shows the total projected precipitation through 8 PM Friday from the Euro.
It looks like 2 waves of low pressure, with the first being the remnants of Zeta, which will bring 1 to 3 inches of rain to Long Island from Thursday morning to Friday afternoon/evening.
