Do not get paniced yet, this is not a SURE thing. It does have the potential to become a "super storm", but not there yet.
Here, add Weather Underground to your list of weather to watch. Personally I have found Accuweather to be the least accurate more than 12 hours out. Weather Channel tv gives a pretty good big picture with the potentials
Here is a link for Weather Underground regular page. Put in your zip and get your local forecast. The one I have sent it for Glen Rock, PA as I do not know where you are located.

From Weather Underground:
For now...the typical uncertainties with timing...track and
intensity of upper level and boundary layer features are in play.
The operational European model (ecmwf) had been the most consistent and impressive
during the past 36 to 48 hours...depicting what could best be
characterized as a superstorm-type solution that (if verified)
would produce widespread heavy snowfall over central and eastern
Pennsylvania. However...Saturday European model (ecmwf) runs indicated a
significant eastward shift to what had been a consistent
solution...both in terms of track and intensity. This is to be
expected for the majority of ecws scenarios days in advance...and
does not diminish the potential persay of a large winter storm. It
does however underscore the importance of expressing uncertainty
this far in advance of a potentially large storm...and to focus on
communicating that uncertainty along with trends.
