All of NE MA including Boston and Essex and Middlesex counties will see snow fill in tonight. Radar presentation suggests at least some snow there with a strong band heading towards the South Shore.
Scott should be here, the band is heading northwest from the Cape to that area. I would not be surprised we see the pivot point on the Cape this overnight.
I think the low is further north, than models indicated, and could be tracking between ACK and the BM. You can see the location of the low on satellite right now check the infrared imagery.
Radar from Taunton, MA shows the easterly surface inflow developing with precipitation blossoming to the east. This will combine with the synoptic banding for snow tonight.
