Your joking right? Wow he never says anything like that. Hum....??

I did see him post and talk about a brutal winter, however .. I haven't seen him post or say anything about this weekends storm. We shall see.
Also remember, usually we see the most changes within the storm range of D3-5 ( storm starting time) which we are all up in that window now
U knew what I mean...but to think about it, he said southeast
Where did he say that?

Fwiw the 18z ICON is even more suppressed so far through hour 78.

Take anything he says with a grain of salt. He foretasted a dusting to an inch of snow last December and we got blasted. They are going to rely on the GFS right now, and he did mean south and east.

He just said as a tease for his forecast to expect a wintry mix with sleet and snow starting Saturday and more to follow. Maps to follow in newsca

ya'll scored big time twice last year. I got cold rain in mby but just 5 miles north of my pure snow. I was so upset. Hope the tables are turned this time.

What? Really? Glen Burns said that? Wow!!
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.Here are the dewpoints from the last frame of the NAM.

Fwiw compare the NAM dewpoints to the GFS for the same time.

GFS CAD erosion is always comical lol.

Yeah the 18z ICON is much further south so far this run
Yes, things have shifted south a bit verses 12z GFS.
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

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.
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!!
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.
Yep, boundaries from cad can enhance llvl helicity

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
