So… yesterday the GFS 18z shoved the storm way to the south… and today it's putting it right back up in the Great Lakes region again. I can honestly say… I haven't seen the models ever flop so much. Interesting, but my heart is like a yo-yo right now. LOL
Crossing my fingers!!! 
I do have one question out there for you met's though… is there a blocking high pressure system over Ontario or something?? Everytime a system moves into Ohio… for the last couple weeks… it either is shoved southward into southern Ohio or it's completely dissolved coming into Ohio. Just curious??
99% of runs on all models (GFS, Euro, DGEX, GGEM, etc.) have the actual low tracking through the south. And as of now that is where it is going. The low will respawn towards the rockies, dive south into the GOMEX, draw up moisture and head up to the NC coast where if things verify as they stand now, it will bomb out leading to a large winter storm for NC northward.
The two ways that this will go right now:
-Ice/Snow for plains, OV, and Apps then major snowstorm for east coast.
-OTS with a moderate accumulations in the southern Mid-Atlantic and NC.
This has been the dominant look of the storm on the models. The pattern supports this type of “southern slider” storm. It is on the Subtropical Jet Stream.
Fatherfrost, I'm in southwest Pa , what will we get if anything ??
