But will it happen?
I say no. The same ECMWF model run that is showing this superstorm is also showing a major positive NAO (North Atlantic Oscillation). A positive NAO will essentially make a ridge that diverts any storms away from the East Coast. Just simply using that, it is easy to see why this ECMWF run is flawed.
Other than the NAO, The Pacific North American Pattern (PNA) will be in a raging negative phase, indicating the likelihood of a ridge in the East and storm systems in the West half of the country.
