Look at the NAM 500mb starting at 60 hours (ugh, I know). It is trying to create a second UL over eastern WV up into PA. Absolutely not modelled anywhere until now...
Both AIs show a possible nor'easter later next week, but look really good for an SWFE pattern after that. A repeat of 1/25...even at 2/3scale that would be nice.
Perhaps the transition away from PNAP is the moment for a good coastal?
ICON keeps the 500 closed low north of the Tidewater, rather than over Savannah. A rather radical change, I would think.
Edit: Not a huge change over itself, but far from the look of every other model.
They can be squirrelly bastards. Often a very narrow zone of heavy snow, precip-tpye issues, overall very sensitive to small modelling changes.. OTOH, they tend to give SWCT our best chances for huge totals.
