Wintry Dec 8-10th Winter Storm

The fact that this air mass begins to supposedly turn "stale" and we still have a 1036 high to our north is impressive in of itself, 1030+ is usually sufficient to get a strong CAD event in the Carolinas and NE GA.

This bad boy (also in early December) during the early 70s had "just" a 1032 over Pennsylvania and was a ton of fun for much of NC and upstate SC.

for middle Tenn

I wonder once this high gets here the models will trend colder

18z GFS is ugly for RDU

 

[Round Oak Weather]

Also the low being farther north hurt us

Western VA special

I'm certainly not an expert here, but my experience is that I've never seen temperatures go up during a CAD senario like modeled here from 0Z Sunday to 18Z Sunday.

Looks like an Ohio Valley and Mid Atlantic special.

Honestly there's been so many swings in the models, would just look at the ensembles and then look at op models by tommorow night

Looks like the gfs took a step towards the euro. In the north trend. Not good at all

Pathetic that many of us are looking at only our 4th coldest rain of the season with this beautiful setup. Disheartening to say the least

The euro was on the north side of its ensembles . I wouldn’t call it a trend

Even the stuff on the backside is rain this time!

Lol, glad we have a few days remaining.

I'm not sure that it would be with 850s below freezing and temps in the upper 30s, but it certainly wouldn't amount to anything. I just don't buy temps in the low 40s through the majority of the rain event. I twill likely be rain in our area, but colder.

CAD isn't obliterated by strong mid-level WAA (that's assuming there isn't any at the surface on the GFS which doesn't seem like there should be anyway in a CAD like this at least on the front end), that process actually strengthens it and in cases where there's heavy precipitation, while it can warm the low-level dome up to freezing (due to latent heating), this actually augments the CAD in-situ too because the level of maximum latent heating is in the mid-levels capping CAA near the surface.
