Here's my latest. Notice that I've nudged contours from yesterday's outlook map ~30 miles to the north & west. Timing is a bit slower...and warm air aloft is just as aggressive as I imagined. So, more wet than white across SE PA...but a snowy, icy mess for central & northern PA. pic.twitter.com/VPKrgb3Qa6
