White Wednesday Before Black Friday?

National Weather Service NYC says
IT WILL NOT TAKE TOO MUCH TO GO FROM
ALL SNOW AND VICE VERSA…

SO THIS IS WHERE THERE IS SIGNIFICANT
UNCERTAINTY IN THE FORECAST. HOWEVER…INTERIOR LOCATIONS CONFIDENCE
OF A PRIMARILY SNOW EVENT IS MUCH HIGHER THAN THE Precipitation TYPE FORECAST AT
THE COAST.

SNOWFALL AMOUNTS WILL RANGE FROM 6 TO 10 INCHES IN THE WATCH
AREA…TO AS LITTLE AS 1 TO 2 INCHES ACROSS THE EASTERN FORKS OF
LONG ISLAND. RAIN WILL CHANGE TO ALL SNOW ACROSS THE INTERIOR BY
NOONTIME…AND MIX WITH OR CHANGE TO SNOW DURING THE AFTERNOON HOURS
AT THE COAST.
634pm Monday, Nov 21

The question is how much cold air will come into the storm and whether the storm will have some dynamic cooling of its own.
