Wintry Dec 8-10th Winter Storm

[WxWatch]

The ICON looks like it went south

Yes, things have shifted south a bit verses 12z GFS.

I'd like to see those 10's well entrenched down into NC but that's not bad and better than most other guidance I believe.

This is what I'm most interested in. I'd really like to see dew points 15-20 at onset.

Icon looks squashed all to hell at 78. I like it

WSBTV Glenn Burns said he thinks it going to be a Brutal winter with the cold hammer coming in Janurary. ALSO, he believe the wintry precip will expand further southeast! Stay tuned Atlanta

Hmm. Wonder if the public flogging he took on FB and Twitter after he blew off the Dec 17 storm has him rethinking his approach.

OOO Glen Burns, he didnt mention the ULL boo!!! That hype was lame!

GFS CAD erosion is always comical lol.

What's funny is the GFS takes so long to get the CAD going, it hadn't even started then .I have a feeling temps are going to be colder for ALL CAD areas .give me a 1038-1040mb high. Boom!!

I think we will get there

One thing that we can bank on...heavy precip board wide. Pretty amazing how widespread the heavier QPF fields are.

A total noob question, but I did relocate from South LA. What is CAD referring to? Is it a specific type of storm? Certain region of the Carolina's?

Cold Air Damming... It's when cold air funnels down the east side of the mountains.

Cold Air Damming. Cold air from the north gets funneled and trapped (hence the word 'damming') in and along the east side of the Appalachians mainly in NC. It produces enough cold air to get really big snows in that region.

Cad or cold air damming can also protect/sheild cad areas of ga,sc, and nc from severe weather

Never gets old looking at these. GSP to GSO looks to be solid.

Yeah sitting on the far eastern edge of any wedge I'll need any help I can get

Or it could enhance severe weather along the CAD boundary !

Uggghhh...icon stopped running. You know it's a winter storm threat for us when that models stop running mid cycle.

 

[Myfrotho704_]

Yep, boundaries from cad can enhance llvl helicity

I am at the bottom of the edge usually...lmao. I think you have a great shot at getting there bud!

Here’s a pretty good explanation of CAD for us laymen; it also discusses why CAD is so difficult for computer forecast models to properly handle:

For visual learners. Low spins to the south. Cold air funnels in from the NE along the eastern facing slopes of the Appalachian mountains
