In the absence of a -NAO, I'd certainly be concerned about the coming cold staying held back over the Rockies & midwest, but I highly doubt it does as long as we have a giant west-based -NAO in place. It's probably a matter of when not if it gets really cold down here. I've personally been yearning for a couple 60-70F days lately here in NC and it's nice that we might finally seem them
Thank you! GA or Bama as well? plus wanted to see if we have any H5 or SFC maps that he might have.

This is the SC-based map I worked on last night & today. I went thru all of the written publications from voluntary observers for this storm and read a few pieces of literature for additional observations that are missing from most maps & documents you'll find out there. I also added several obs (like the 6.5" in Laurens, SC for ex) based on snow liquid ratios from adjacent stations.
Thank you. Selfishly, would love that storm around here...hahah
Update for this. Now that it is known, I have removed all current warning points and currents bans for people who triggered this system. This is a one-time free reset, try not to do anything to cause it again.
This guy's blog is about as detailed as I've seen for the time.
Remembering The 1973 Snowstorm In South Carolina
February 9-10, 2013 marked the 40 th anniversary of the greatest snowstorm to hit South Carolina in modern times. Snow in the South ...

I don't blame ya. I know NWS ILM has made a nice map of the snow from this storm. I could probably make a more localized one for south-central GA if you'd like.
Here's the z500 vort near the peak of this storm during the night of the 9th into the 10th.
Here's the hemispheric 500mb anomaly map I pulled from NOAA ESRL. Tbh, it was a crappy-looking pattern in a large-scale sense that triggered this storm
I made this a while back but forgot to post it. Here are the pretty precip maps for that storm.
I posted this site this morning, but you can search through some more parameters.

The first link should have H5 or SFC maps associated with the storm.
Thank you! I know the look, as of now, doesn't really look like this but I really could see a good southern slider system for the I-20 corridor south and I-85 and I-40 south. To me....as of now...the pattern screams potential
Thank you!
FWIW icon shifted south

Here is a snippet from James Spann!!!
LONG RANGE IDEAS: While the idea of Arctic air entering the Deep South next week is now off the table, we note very cold air will be looming north of here through next week. Temperatures this morning over Alaska were as cold as -40F, and that kind of air covers much of western Canada and the Arctic region. That air is heavy, and at some point will have to move.
One run of the American GFS model today shows a big snow/ice event for Alabama in 10 days. You will see that plastered all over social media, but it is meaningless at this point. Having said that, the players are on the field for some potential for winter mischief by mid-month. Arctic air and an active southern branch of the jet stream will be watched closely. But, we could go through the entire month of February without a winter storm threat; this is Alabama after all. But, it wouldn’t be a big shock if we have at least a chance of wintry precipitation within the next three weeks. We will see.

Are you ready for the cold ? Looks like you will have highs between 0 and 5 for several days with lows -15 to -20 !

Thank you!
This is actually perking my ears up far more than the ten day system.
Oh come on now

baby steps just like with our little event last week.....
wedges by 00z tomorrow? At least there’s no S/W trough (yet) 
We really have to give the ICON some credit for spotting this.
Hey December 2017 went from suppression to 9-12” in three days. Sooooo.
Imagine if that digs more out west ? 
lol that increase of ridging in the NPAC really changed everything, were trending towards a favorable look for severe over winter in the medium range 
And oh....
And oh....

Think we can get a two-for-one deal on the wedges?
It’s gonna slide East tho, thanks to the -NAO 
All factz!
and here it comes

It honestly makes it a bit more believable if you ask me. This wouldn't be the first time that it would've happened either.
Recall March 1st 2009- There were tornadoes and severe storms all across Alabama and West Georgia on Saturday February 28th. I saw that a winter storm watch was posted for north and central Alabama. In Auburn, AL (where I was living at the time), the temp reached 79 with bright sunshine after the storms rolled out. 12 hours later, it was nuking snow- ended up with a little over 4 inches on campus.
Not surprising at all if we see these extremes.
Happy hr goof has temps pushing 70 across Alabama, Georgia & South Carolina @ 165 with a massive gradient back to the north and west.
@Brick Tamland ....is it happening?
?

Oh mama
Yeah I think most of SC except for the northern Upstate and eastern NC will sneak a mild day, but I have a feeling the rest of us will be wedge in out ahead of this front. There’s just such a good snowpack to our north now and with that -NAO it’s gonna be hard to stay out of that wedge. For the folks that do get 60s/70, they might get to experience one of my favorite weather events... the 25+ degree day to day temp drop
