Here is a worst case scenario, if you want to know.  Heavy snow from Norfolk to Allentown, Poughkeepsie, NYC, Long Island.  18" + snow.  60 to 70 mph winds at Jersey shore. Coastal flooding.  All travel shut down. Power outages.

Scary huh?  It could happen if it all pans out a la Euro.  The Euro computer is predicting that, the others are not.
