Let me remind everyone that the last time the GFS at 06z showed a snowstorm for the mid-Atlantic, 6 hours later when a full load of new data had been loaded into the 12z, that storm completely disappeared from the radar never to reappear on any future run of that model. That was fact not fiction like this run most likely is.
It will change every six hours till right before the event and it will be all rain with a mix of snow/sleet. Unless you’re located in upstate New York and Northern New England where it will be all snow
