Here's what I've gather so far...
As mentioned, it looks like Sandy will be a tropical storm by the time it reaches mid-PA (approx. 50 mph). Looks like it will have this "Nor'easter" effect because the winds, going counterclockwise, will pick up colder air from the northeast and pull it down on the west side of the storm (PA) making it a cold and wet "tropical" storm.
Looks like PA also at the same time gets hit with this other northwest cold front storm. Not sure of the exact effects of this convergence but it seems like it would be more cold and snow than flooding. Not sure what the wind effect would be.
BTW, here's a link to a pretty good real-time view of the hurricane and its projected path.

Praying for you.
Not to sound alarmist but that sounds like the “snow bomb” nor’easter that stalled out over southeastern North Carolina in late January, 2000. It started spinning up over land in the vicinity of Ft. bragg, even had an eye. Very unusual, snowfall amounts were impressive. I’m nearly 200 miles away and got a foot. Some areas were over two feet, heavy wet snow, roofs were collapsing.
