When you have the out of region heavy hitters watching and posting, you know you have something legit on your hands. These early cells look intense. Still watching that one west of Hagerstown. Hail look to that one now with another big cell developing north just over the MD/PA border.

It's an overblown concern IMO, people say that after every storm. 

Right.  I would doubt those that DO get hammered by any storms are going to say the threat was overblown or "complaining" about a bust, despite many others perhaps not getting anything too bad.  Not the same animal as a large-scale snow event that underperforms almost everywhere.
