Increased snowfall amounts from the National Weather Service!
This is due to the higher snow ratios as I was posting about. The following is just now from the National Weather Service covering Long Island and the Tri-state area:
Updated forecast to increase snowfall amounts across eastern Long Island and southeast Connecticut based on latest radar trends. Several observations across southeast Nassau and southern Suffolk of 5-7" already support an increase in snow totals as well. The snow characteristic is drier due to the colder profiles and likely contributing to higher ratios and more efficient accumulation. Blowing and drifting of snow will occur as well. Banding continues to increase and there are signs of the deformation axis setting up somewhere just east of NYC into Nassau County. Several mesoscale snow bands continue to rotate in from the south and east and converge near this axis. Snowfall rates around 1" per hour possible and could be as high as 2-3" per hour especially through the morning across eastern Long Island. No changes made to the ongoing headlines, but snowfall totals were adjusted and some areas across the east end of Long Island could see close to 20" by the time the snow diminishes this evening.
