Last night, I threw out the idea of the storm whipping around the trough and went with Sandy coming into N.J. I recognized the low NAO and the potential for a storm, but thought the storm would come from the trough digging in and not Sandy. But as it turned out, Sandy will be the storm that is a product of the low NAO.
My track has Sandy going in across central New Jersey and looping around eastern Pennsylvania before heading out to the Northeast. Keep in mind, Sandy will go from tropical to extra-tropical storm and the wind field will spread out. In fact, as Sandy goes through the transition, the pressure will continue to fall as she approaches the coast which is why it makes Sandy even more dangerous. It's not that Sandy has a weakening coming, but Sandy is getting stronger as it comes into the coast with a widening wind field.
The maps below show the impacts with Sandy.
