Likely way overdone to say the least this run, but the 6z GFS had the general idea of a low tracking towards Ohio & then forming a secondary in response to the blocking in the Northeast. The good recent off & on runs the last few days of the Euro & the AI models had this same general idea. The 6z GFS just gets the coastal going a little earlier & then rapidly strengthens it, producing a historic result, that is of course unlikely.
