Yeah the radar hole, which is at its worst over the Lebanon/Schuylkill County areas and particularly bad for low-topped cloud events, is a real issue that everyone is aware of. You have to rely on visible satellites, highway cams, on-the-ground reports, and the like. Not ideal. Eric Horst was tweeting about this after the event and mentioned the push to get another weather radar somewhere in the vicinity of MDT or MU; not sure if there is really anything to that but it would go a long way towards solving the problem. It frustrates all of us.
