Completely agreee. It was historic for this area. Most I’ve seen in GA since March 93. I think we got more snow this time but the wind and drifts in 93 were unreal. And a blizzard warning is pretty cool.

It's not for nearly 90% of the state usually just the two rows along the GA boarder (along the Apps and points E) that see anything from most of these CAD events I've seen rest of the state in the upper 40's and 50's while this was ongoing

Where are you viewing the 925 mb temps?
Depends on how deep the cold is. It could be a bigger deal for the valleys where he cold air can leach down. Personally if AL gets involved take your finger and trace from whereal the Tallapoosa comes into AL down to Lake Martin. That is your battle area.

From Robert Gamble at wxsouth:
After catching my breath, and regaining conciousness from viewing all the afternoon data and ensembles suite--I'd have to say this looks very ominous. Still 5 to 7 days out though, and subtle shifts could occur--but the least likely shift would be on the low level Arctic Cold temps. With precip falling, temps will be in the lower 20s throughout piedmont Carolinas, mid 20's Atlanta metro during heart of the event, even upper teens for temps in part of Virginia, eastern West Virginia--so snow ratios would be much higher than a typical 10 to 1 Ratio.
Imagine having 1" or more of Liquid Precip fall into air that is 27 degrees? I'm talking to you Georgia and South Carolina.

Correct if I m wrong but 0C or Below at 925 mb AND lower, with above 0C above.(850 etc)
Jeeze, the Euro control (which is lighter than most members in regards to precip totals) has the 32F line to the SC coast:
That freezing line into AL is very concerning, as is the lighter precip. Not only would the lighter precip not pull down the warmer temps above the surface, it also would limit latent heat release from freezing droplets. That also on top of higher ice accrual rates.
All this I'm taking about into AL where temps would be more borderline. Bottom line, nasty setup.

Ok I tried to map this out with topography to show how it effects E central AL folks usually. Of course this is dependent oh HP location and strength but most CAD events for this area go like so

Great map.

Sounds like an appropriate time to mention the SPIA Ice Damage Index, which factors in wind strength...

The blue lines I'm tried to show where it drains and feathers out thru the App's... The brighter is higher elevation of course and usually have no issue icing up...i habe seem it go farther W to about the I-65 corridor but it rarely happens unless it is a massive MB high and placement is farther S

Good map. The nose including Gadsden is fact. Probably parts of Scottsboro and Fort Payne included. Maybe Far East Blount.Ok I tried to map this out with topography to show how it effects E central AL folks usually.

I am extremely interested to see if my area can avoid most of this being fr rain. Hoping for more sleet...I think it can happen.

Agree, plenty of time for it to trend colder

Yes I was little of up on the northern part here is another map you can literally see the drain pattern in the area I outlined a moment ago. Most of the time it is hard to get it back any farther West say towards Blount Eastern Jefferson the cold dense air doesn't want to climb again unless strong HP
