What a great 12z GFS run for CTP for this week!
First, on Tuesday, there is a chance for 1 or 2 inches of snow, mostly north of the turnpike with a weak system.
Then the real fun begins Wednesday night with the start of the overrunning snow. The snow then continues at varying intensity until early Friday. This run keeps most of PA all snow for this event.
The snow map is just for this event.
