Wintry 1/9-12 Winter Potential Great Dane or Yorkie

GFS actually with some little nudges of improvement overall for the deep south that's promising but again models are all over place shouldn't surprise too much
 
I don't see this happening. Not to say I know what will happen but I bet it's not this

For new members, these high ice accumulation maps rarely, if ever, happen. Especially from the cold bias Canadian model.
Not saying it's impossible, but it's unlikely.
 
Here's a 12z model summary for Clemson, SC.

I'm all for living and dying on every model run - that's part of the deal in here. But we gotta keep it 💯 too. The overall trends with recent models runs have been flatter, not more amped - save this run of the GFS. The Euro, EPS, the AI suite, the ICON all have trended flatter overnight. The CMC run was basically the same at 500mb from its previous run. Of course this could end up way amped and west at go time, but we can't say we are seeing that in the overnight trends. Here is the trend on the last 3 runs of the Euro

just my guess off the crummy maps... but 12z ukmet has a strong northern trough dropping down, but it keeps it positive tilted... probably a great run for upstate and also Eastern sections of NC.... stronger front end, but no amplication on the backend should keep the warm nose at bay I think. Hopefully it is generous with precip.

Are we thinking there is a legit freezing rain chance here for this system for the CAD regions? Say NE Atlanta and points north and east?
 
Good gosh (not going to happen):

Nope.... never seen freezing rain in all those areas at the same time.... Impossible. Not gonna happen. There will be transition zones. The wedge will not extend that far south without there being some very cold temps aloft and at the surface in NC. If there is freezing rain in Wilmington and Myrtle Beech, then Charlotte will get frozen. Gfs is smoking crack...

That was the CMC, GFS had rain for those far eastern areas
 
I feel like the 2m temp profiles on the CMC will probably come closest to verifying, the AIFS and Euro have been trending colder and colder.

@Myfrotho704_ this is looking like a classic SE CAD storm for us and other W. Piedmont folk
I agree and I think the CAD is going to get colder each model run. And the low will be push further southwest.
 

I think we are getting the idea, finally. Precipitation types and lines will still be a nightmare to figure out, but we are going to end up with a mess, and a couple +SN surprises in locations just far away from the WAA.

When these systems get going, someone always scores where the 0 to 0.5 850mb temps are right on their doorstep.
