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

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.
