If you see 2 or 3 closed 500mb contours SE of LI, really nothing else to be said-those have been our top snowfall producing setups. Inland wouldn't do quite as well but maybe close because of less wind (wind can hamper ratios by breaking up the flakes) and excellent moisture transport in the CCB. And we all know these love to put a NW fronto band in there somewhere like West Milford which always seems to get hammered in these.
