That GFS 12z has to be one of the worst runs I've seen in recent times - aside from high winds, I can't think of much worse than this, really! Just under an inch of rain, and 2 or 3 degrees above freezing. Awful.
You can see, though, where the disruptive potential comes from... as some places would be getting close to a foot of snow from that!
