This initial band may be the forcing along that back Bent warm front. The stuff south of it is showery. Watch echoes continue to reform and watch that band slowly start becoming more E-W.
That area in nrn MA and esp srn NH is going to get croaked I think. Nice signals of the whole flow turning more easterly and prolonging heavier precip.
Despite the temp, it must be wetbulbing nicely aloft. The snow is blowing around with the wind. Not the messy slush parachutes you'd expect. Steady light snow.
