The map at the top is my snow forecast for Saturday late afternoon into Sunday morning. This seems fair considering latest weather model guidance. Snow begins in the afternoon from Southeast PA southward and across NYC and points northeast Saturday evening.
The bottom map is is the NAM weather model (North American Model) snowfall forecast. It is the most aggressive of all the weather models out there today. It seems overdone and you might want to cut the amounts in half. This is for snowfall Saturday afternoon into Sunday morning.
