Seriously. Best models days were just before the HECS events in 2009, 2010, and 2016 when the models dumped 2.5"+ liquid on us on every single piece of guidance. That FV3 plot is just silly impossible model porn that will change in 6 hours.
I would take the globals and smooth out the precip maps on them. They aren't going to be too good at nailing anything too specific in that regard. Snow max could end up anywhere from RIC to Mason/Dixon line.
