Wherever the Norlun Trough sets up will be where you have a sweet spot 4-6" most likely east to west I would think through Chester, Delaware County, then move ENE from there south of the Mason Dixon Line is drops off for now. The Vort to our south cruising just south of Baltimore or DC needs to drop just a bit more to affect more people with the moderate snow band. Also, I would think to see these changes at 0z tonight and see if we can increase the ascent of warm air up and over the top as this clipper like system glides to our south and hands off to a developing coastal moving out to sea. This is a tricky situation, but for now I favor Extreme SE Pa over to Central New Jersey over to Ocean County.
