The European ECM Model is showing a strong Nor'easter Wednesday night. This model handled Sandy the best.

It’s not a certainty..yet, but the risk of a significant Nor’easter bringing wind, rain and snow to the areas hardest hit by Sandy is increasing tonight. If the overnight model runs come up with nearly the same solution then folks up here will need to prepare for winds over 50 mph. Snow is possible on the inland side of the storm as well as cold air flows into the storm. With damaged dunes along the shore, even a moderate onshore flow will cause some high waters and delay the restoration of power.

The U.S. Global model is also hinting strongly at a strong low developing. See below:

The gfs model (NOAA) also indicates a strong storm. This is the 18Z run from Saturday.
