I agree. I have 3-6” for my area up thru ORH and then light rain / drizzle at 34-35 for a few hours before it ends as a period of light snow Monday night . I highly doubt any 50’s or 60 except perhaps the Cape . Climo always has these form weak secondary along coast. It’s just physics.
2.5 days out . I am quite sure that map will not verify . Either it’s much too low for the whole region .. or .. it’s too high. I just think that scenario there is least likely
