Good catch, here are this CTP comments.
“there remains some model spread in the exact low track, which could alter exactly where the heaviest precipitation falls. The 18Z EPS for instance now tracks the surface low a bit further south, which could result in the heaviest precipitation falling over extreme Southern PA and shift the axis of heaviest snow from just north of I-80 to just south of it. Marginal surface temperatures and uncertainty where the potential CSI banding occurs argues for riding the current Winter Storm Watch over much of the region. Still can`t rule out significant snow as far south as the I-81 corridor based on the latest southern shift in the models.”
