It will but you have to let the run finish or just after. Yeah, super annoying...and the 48hr, 120hr snow maps don't work.

This is quickly looking like a lock for at least minor/moderate snow in the upstate. We should get something even with the less-amped solutions thanks to the Lee-side convergence zone as the vort passes overhead.
And the more-amped solutions are even better than that for us.

What models are not able to hone in at this point are things like Thermal profiles, placement of low and high pressure, track and timing. Looking at this synoptically, it seems this will come back some NW as we get closer to go time but how much is unknown. This will be determined by the movement of the high pressure to our North and the area where the cyclogenesus gets wound up. Even if it stays offshore (not too far) the precipitation field will expand further North and West than the models will show, happens every time.

WeatherNext almost seems like a mix between the less amped GFS and the more amped EURO. Almost closer to the CMC.

I would imagine those totals are underestimated over the Carolinas because ratios will be quite a bit higher than 10 to 1. Same goes for the ensembles

Biggest fail mode here is if the vort pass starts trending farther to the north. That’s bad for everybody except maybe the northeast.
Would be concerned if we see weathernext trend this way the next few cycles but so far so good. Insane we are 108-120hrs out and not 240+.

I haven’t looked at the 5h maps, but this feels like it could be like the 2004 storm. Where you got a weak gulf low that gives 2-5 inches to Alabama/georgia, then a transfer to a coastal bomb that gives charlotte 2 feet… meanwhile my house gets a feather dusting.
Let’s hope it’s not that.
Edit: 5h pattern not all that similar

Yeah, the two ways to fail is if the low sweeps out to sea quickly or if the northern stream is too far north and east and the storm doesn't get started far enough south. It would be a mid-Atlantic, Northeast deal.
Y’all are gonna wishcast this to rain here. But given the recent northerly trends with past storms, that was probably a given anyway.

This trending north is going to be a problem. Not for cold but for where this thing eventually wraps up. West Virginia and Pennsylvania licking their chop

Man thats a big increase for the upstate!

Yeah we are trending the vort into a better position out west, but it doesn’t need to go too far west either

Oh hell you had to mention that disaster. At first glance yesterday that's all I could think of..was actually scared to look this morning. But now I think we are o k for a light event at least

Oh yeah, that one was nasty for Oconee and Pickens counties. Little to nothing there, while I get 1 foot here and other parts of my county get 18+. I don't see it happening, but what this board needs is a Jan 1988 repeat. 95% of the board would be hit if that happened again. All the way from OK and TX to the Carolinas and VA.
6z WeatherNext snowfall probability thresholds.
WeatherNext is clearly a little under dispersed, but considering the run-to-run consistency and the track record, this is very high confidence from the model.

Yall the weathernext model is pretty much locked in and that’s saying something as it was locked in on this weekends storm at this range. I think this will be a decent storm for many on this forum.

That is an amazing look for you guys west of here. I dream of heavy powder falling at 15 degrees
While this might not be an Alabama “Storm”, looks like we might get a bit of snow Northeast of I59-I20. Worth watching.
I encourage you to read closely the maps @bouncycorn just posted literally 3 posts before yours, 20 mins ago, and see if you can answer your own question. If you’re not sure where Atlanta is without labels, can pull up a county map on Google. Really helpful when reading weather maps to find your own county.
The latest 06z WeatherNext Ens run was without a doubt the best one I've seen for the eastern / northeastern areas of the forum. The EPS and WNext are quite similar with the storm right now.....but where do we trend??

There's definitely a chance for some snow in ATL-Athens corridor if there's earlier cyclogenesis in the gulf. WeatherNext kind of hints at this. You would need the northern stream to dig futher west and south.

Let’s be careful. It isn’t locked in until the precip and height fields stop bouncing around so much from run to run. It’s almost there but for the last storm it was only locked at 120 hours. I’d wait at least a day.
I mean precip is cranking in the gulf by hr 96, wow.
Just just eyeballing the 6z Euro AI and trying to estimate what that looks like for GA specifically I-20 and then to East the most of this falls under very cold temps would be all snow and slightly better ratios. It's a 1-3 inch event for western counties and grows moving toward the Carolinas upward in totals

Grit, question--the orientation of this coastal NE->SW on its snow print looks kind of odd to me for storms that tend to form and move up the coast. What do you think is going on there?
would you mind adding the aifs ens to this with similar parameters? curious what that story tells and if it's similar to weathernext
Will be a another good test, but this is much trickier IMO.

No, IK it isn’t Set, but unless I see something other than a Bombing Coastal I’m not overly excited for Western Carolina’s. We need a traditional Gulf LP
Granted I’m speaking for I-77 an West / NW in SC / NC
Track A - Heavier Totals (Ride the Line of RN/SN in Miller A)
Track B - Moderate Totals (Far enough NW No Rain in Miller A)
Track C - Imo Too Far NW I’ve scraped a 1-3” out out of this but primarily a East of 77 event

something must be done about AIFS snow maps
Just added to the original post
I am near ATL and I think this is a great look at this range. Though it is an even better look for the Carolinas
Yeah, for sure, we shouldn’t refer to them as snow maps. Really just frozen probability maps.
Notice he went with the most northerly map looks. Who knows, he's maybe more right than wrong.

Not necessarily. He moreso just used later frames of the runs which focus more on the northern areas
