Jeffrey Gluck’s note

A developing coastal low will bring accumulating snow to the NYC metro area. NYC proper sees 4-8 inches with a sharp gradient - Long Island stays lighter (2-6) while the Hudson Valley gets hammered with 7-13 inches thanks to enhanced orographic lift.

Based on 12z GFS/ECMWF/NAM blend.
