That look has big dog potential given it’s probably gonna be juiced if it isn’t squished by a vortex
If we can get that trough to slide over top, get it to amplify to our N near us and eject out the southern wave ?

Yeah it definitely does. Here's a few early December big dogs I was able to dig up on that apparently had similar longwave patterns.
December 2-3 1896
December 4-5 1907
December 4 2000
Composite mean 500mb anomaly from the above 3 storms

You can get active subtropical jets in a multitude of ways without El Nino, a Kelvin or MJO wave, +PMM (as we'll see this coming week), and equatorward breaking rossby wave on the dynamic tropopause in the right place and orientation can deposit a significant amount of westerly momentum onto the subtropical jet.
I could be wrong but, wouldn't there be a caveat since there's a ridge south of Greenland rather than a trough that would pump cold air?

Yeah the trough there is a key distinction and something we may need to see as this moves forward in time. A trough south of Greenland pushes the North Atlantic storm track southward, delivers a cold high to our north over New England and southeastern Canada and helps slow the background flow just enough for the wave in the southern stream to amplify and tilt just in the nick of time to produce here. We can certainly do without the trough there but it would help no doubt imo

I think it was Dec 4-5, 2002. Raleigh had their most freezing rain from a single storm since 1948.
Such an exciting advisory map tonight across the US:
I remember that storm well. I was living in Concord and after about a 1/2 inch of sleet/snow it switched over to 18 hours of freezing rain with the temperature hovering between 27-29. The ice accrued to just under an inch which was the most I’ve personally experienced. Power was out for a longer time after that than with Hugo

Trust me nashville is a huge heat island but it’s much further north then Atlanta. I’m 40 minutes north of Nashville and have seen many times driving from Nashville to White House at night temp drops of 10 degrees. Look at the gfs on weather bell using the 2m temps and you can literally see a bubble of warm air surrounding Nashville, especially at night when cooler temps are ongoing

It was the worst ice storm in history over this way . Over an inch of freezing rain ice acruel. Brutal

swing and miss, need slower southern wave/faster trough to swing in from the NW into SE Canada but pattern is definitely there 
00z GFS wants to go for some more Max LO records ?
Ayo wtf 
Just goes to show you the lack of confidence there is in the 10 day period.
CMC and ICON are aligned, and the GFS and Euro are in another alignment camp.

Doubt it?
