With such a sustained, power ful press of arctic air coming down, I'm not sure how further north this climbs. In some sense, this reminds me of the December 2009 snow event for PA. There was the last second nudge north that brough warning level snowfall (6"+) to the southern tier, but the cutoff was sharp. In eastern PA, Allentown was almost smoking cirrus while it was piling up in Philly and Lancaster.
