With temps being the biggest question, specifically how quickly the column cools, the NWS outlook is reasonable.
Just an OT side note, but it's kinda funny how the algorithm for these model snow maps make most of Allegheny county a giant UHI.
In reality it's mostly just the valley floors, that lose a lot of snowfall accumulation. Obviously these maps are taken with a giant grain of salt, just something I've noticed the past few years.
