Polar vortex is definitely happening, its just the question of how much it dumps south into PA.. which models have been toying around with the last couple days. 12z models today has the Euro as colder than the GFS. Wed-Fri looks to be the brunt of the arctic air intrusion with Thursday as the absolute coldest. For Thursday GFS had high singles for while Euro looked debatable if it reached 0 in H-burg. Either number for a high is hard to do in the Sus Valley. Interior Central PA was in the -10s on both (Euro colder) on both models for Wed night. Wind and prospective snow on the ground could dictate an even lower bottom to low temperatures. 

If we get a 4 to 8 event definitely looking much colder.

Looks like maybe a few inches here Monday night into Tuesday.
