Snow Amounts, What To Expect

A very large and dynamic system is moving into our area. Already snow has broken out in NC and VA. As it moves up, it will enter our area as a brief period of snow or sleet and change to rain. It may rain a large majority of the day. Once the disturbance from our west phases, our temperatures will drop and things will begin to rock and roll. Rain will change to snow and it will snow heavy at times. Winds will kick up to 20-30 mph and be gusty. Thundersnow cannot be ruled out either. It will snow for a good part of the night before tapering to flurries early Sat. Here is what I am looking for, unchanged from earlier.
SNOWFALL AMOUNTS:

Philly south to NE MD: 1-3"
Philly North to 195 3-6"
195 North to 78 6-10"
78- NYC 10-12"
Lower Hudson Valley - RT 91 in CT 12-20"
RT 91 to East Coast 20-30"
