Sandy looks to be a menace or a downright historic storm possibly for the eastern U.S. Its alarming to me that the European which continue to advertise a significant storm recurving NW into the Northeast next week. After really scratching my head and seeing a track like that is quite rare if at all, but its does have support from the Nogaps,GEM, and GFS ensemble members. Its interaction with the Omega block consisting of a blocking high in the north Atlantic, and a large ocean storm over the central north Atlantic, and a digging negatively tilted upper trough over the Ohio valley will be critical in determining where Sandy goes. But Iam starting to think Sandy may miss her chance out to the northeast like GFS says with it undercutting the block. Time will tell but I would watch this very very closely!
