That was a simple one. I know what Cold Air Damming is, but just never put that CAD is what that stands for. Thanks for your invitation to join in, b ut I am a lurker by nature

Still both are too aggressive along the Carolina coast with 850mb warming, (in which the 0z EC does NOT agree with), b/c the continual BS of bringing a coastal trough inland (last week, it was correct, but the CAD wasn't strong here, either) .... but this time, this is a strong cold air damming high ... it won't scour out.
Moisture has trended a bit less. A check of the model run diagnostics and such, indicate that the 12z runs have good coverage of the US/CANADA and MEXICAN RAOBS ... so as it stands, at least data coverage appears decent ... 12z ECMWF will be interesting (especially WRT to the SW low) ... which now appears MIGHT be correct ... all the models are starting to trend towards a SW cutoff low ...
QC, you're still in the game ...

We're all set except for bread and milk, and to re-fill our propane tank for the gas grill. Looks like I know what I'll be doing tonight. Getting ready and saying prayers that our house will be spared this time. We've got an alternate heat source and cooking, so....I guess whatever will be, will be.
Not looking forward to ice. Especially not "significant" or "historic" ice storm.
Why can't this just be snow?

Sorry, Jeny ... like to tell you otherwise, but thermal profiles don't support the onset of snow this time, since the temperatures between 2,000 and 5,000 ft ABV the SFC are warmer than the 2 M (SFC) temperatures ... (nature of CAD/wedging) - since the moisture comes in during the height (peak) of the CAD, ATL really has some problems ahead ...

I know it... but Atlanta's overdue. It's been what, 5 years since the last ice storm? I wish you the best... without giving too much away, could you tell me what part of the metro you live in?

I'll try to have an update today as things warrant, provided I feel well enough to do so ..
