00z and 6z models have brought an increasing amount of confidence that a significant snowstorm will impact the region sometime Saturday through Saturday night.  This looks like an all snow event once again, however, the dynamics are much better with a strengthening storm center passing just southeast of the benchmark.  Snow favors Cape and Islands and most of SE MA from the BOS to PVD corridor of I95 southeastward.  Cape Cod and the Islands have the best shot at a foot or more of snow.
