There appears to be a drying area just ahead of that heavy band down in south central PA. Is some energy being robbed from the lighter precipitation to to feed the heavy band?

Could be some subsidence behind the initial push of snow.  I think people need to step away from the radar for 30min or so because I don't see anything bad developing or not developing.  The real business isn't supposed to be cranking until sunset to our south.

The dry area 5 miles to my south  1.5 hrs ago never made it here if it means anything.

Something like that. The heavier band is associated with stronger upward motion, but to compensate there is downward motion on either flank of the band. Hence the subsidence-induced drying.

I wouldn't say energy is being "robbed" from one band to the other, more like one area of enhanced lift leads to enhanced area of downward motion next to it. The ol' "what goes up, must come down" applies here. So it would dissipated due to localized subsidence. This is what can separate the men from the boys in big snow storms, when a deform band sets up, you can get hammered if you're under it, but significantly lesser amounts on the edge where the downward motion occurs
