Really, there are fine details, but this is about as consistent as a model run can be vs. its prior run, esp. given complex pattern.
Agree.. the transition of temps through the column as CAD builds and precip advances isn't going to get shaken out until it's nearly go time

12z GFS a trending back stronger with the CAD high

FV3 still in line with prev run for the most part. Mercy that's a lot of precip.

As expected the snow map wasnt quite as crazy with amounts due to slightly less QPF.
Don't look at the snow maps, look at QPF

Ginormous south trend in 0z CMC.
Yup.. CMC finally got a clue. Even has the UL bonus snow on Tuesday rolling through.

not very often you see an upper low diving southeast into georgia...drops another 0.25 to 0.40 of mostly snow too. hopefully the fv3 is even more bullish.
0z canadian does the same thing btw.
Yep, and I've always noticed the UL progression most always trends stronger at the last minute with a cutoff with this big snowstorms.. always the last piece of the puzzle
-
GFS definitely trending toward its successor WRT the upper level low swing through early Tuesday

Through 90 there is less total precip over WNC
No, it's not. It's pretty much on par with the prev run thru 96

well the 0z gfs holds in showing much warmer temps. If our suspicions are correct, this could be an epic bust on it's way out the door. Nam is up to 8 degrees colder than the gfs over north ga.
It's the GFS, and at this range what's the surprise?
-
The northern s/w is less strung out and more defined like the NAM... that's likely given the resolution. I think the late phase and cutoff UL solution is looking better.
-
Pretty minor differences at this range.. within 20-30 miles by the looks of it.. overall setup is similar
-
At 72, the low is in the same place.. Minor differences.. perhaps a hair more north with the precip sheild
-
The ICON, which has no knowledge of CAD, has trended back south. Gives the mtns a real shellacking.

Instead it's an 84 hour NAM fantasy storm.
This is preferred.

NAM builds in a 1040mb banana high over the OH valley to the NE. You can't ask for anything better. It's like an old 384hr GFS fantasy storm coming true.

It then rapidly builds the cold air in as the storm approaches. I'll take that. I'll also echo Wow's sentiments about the NAM.
The wonders of low dewpoints as precip builds in. God bless CAD.

A moisture-laden storm will bring heavy precipitation to parts of the Southeast and Lower Middle Atlantic region during the December 9-11 period. Cities such as Atlanta, Charleston, Pensacola, and Tallahassee could pick up 2" or more precipitation.
As a result, 2018 would rank among the 15 wettest years on record for a number of those cities.
Farther north, the pattern remains consistent with the composite 500 mb patterns that have seen significant accumulations of snow in parts of the Carolinas and Virginia. Further, the guidance has gradually moved into increasing consensus for a moderate to possibly significant snowfall in such cities as Asheville, Charlotte, Greenville-Spartanburg, Raleigh, and Roanoke. With cold air damming likely to precede the storm and a strong ridge likely to block it from turning sharply up the Coast, my confidence in a track favorable to the Lower Middle Atlantic region and parts of the Southeast has continued to increase.
Consistent with many of the notable snowstorms to affect this region, accumulating snow will likely remain south of the Mason-Dixon Line. There is also a possibility that the accumulating snow remains south of Washington, DC and its nearby Virginia suburbs.
The Don has spoken. Thank you, Don.

6:30pm EST Dec. 5: NCEP data issues are causing delays in some model products.
Maybe that's correlated?
There's just too much awesomeness. Good safety measure.

Look, it’s time to be real on this storm. I know we have all become experts on hedging and caveats and flies in the ointment. But I go back the old Wright Wearher boards 20 years ago and we have never, EVER seen a storm modeled like this. Consistent, run after run depiction of a historic event. Three inches of QPF paired with a classic CAD? Yes, the features will be better sampled in a day but I really don’t think Lucy can pull away the football on something like this. Even if the QPF is cut in half it’s still a monster. Even if the CAD is overstated by 100 miles, a large area will see more than a foot.
Bottom line: anything can happen, but I had to eventually wrap my head around a Cat 4 October hurricane and I wish I had accepted the inevitable sooner.
This thing is coming.
Get your ass back in NC!
Having you and burger away from something as potentially memorable as this one is an injustice!
Now if I can get Robert posting on here again...

The r/s line is even a bit more further south than the FV3
