UKMet 850 and Sfc Temp panels are out.  It runs the 850 low thru the heart of GA to NC.  Looks really good for GA mtns to NC mtns...iffy just east of there

Might actually be decent for the Atlanta area this time around. In the January 2017 storm, the 850 mb low went slightly to the north of Atlanta if I recall so the warmer 850 winds are coming in from the southwest and could never change over quickly enough. If it actually goes South of Atlanta, I might be a little more confident this time around.

i'd say it's a little better

Euro adds to yet another model showing that warm bubble in East GA/Upstate SC lol. Limiting any real chance of decent accumulation there. Everything I'm seeing says you want to either be North or West of Atlanta when this thing hits. Sucks for me and other East metro residents, but not surprised.

Definintely agreement on the leading wave for Friday to put down a light stripe from S MS thru CLT.  Question is if the southern wave axis starts to turn more neutral and bring in a continuing slug of precip for most of Saturday like the NAM/CMC/UKMET/NAVGEM

I’m just west of Atlanta at home and work on acworth. Trends today have been amazing for this area.

again, i'm not terribly worried... I don't think the models are accurately showing surface temps based on the full soundings.  There could be some delay, maybe an hour or two vs elsewhere but it shouldn't matter a lot if there is sustained precip and decent rates. This run is a good 5 degrees colder than the previous runs here. Our biggest concern should be total precip amounts/rates not being heavy enough to dynamically/evap cool the column or any warm nose centered around 800mb..which the nam shows making it just to athens to elberton or so for a brief time before retreating back south. 

Good run for atlanta metro...they don't seem to have to worry about any of that based on most of the modeling....unless it ends up like the uk where they would end up mostly rain and snow would be mostly confined to west and north of the city.

Yea, EURO still doesnt look like UKMET or CMC... Its a little bit of a compromise between those 2 and GFS 

Snowmap shows Coldrain jackpot over 6 inches lol

Hard for me to tell if that map has "Cary" in the heavy wet snow jackpot or not.  Can anyone post it with counties shown?

I still believe we will see a system leaning toward the more amped versions. This has been an evolving thing the last couple of days, whereas the models are playing catchup with the strength of the trough and with the continuation of moving the GL further north, northeast.

The Op Euro since the upgrade 2 winters ago in systems that aren’t overly strong at the surface has tended to have a flat bias.  I think the ensembles are definitely going to be more north and west.   The Euro also tends to make slow adjustments.  Sometimes if models are catching onto the setup late the Euro can still be making adjustments inside 12-18 hours

At 48-60 hours?   This should be in its wheelhouse now.  I would be surprised if the EPS is much further west and would expect spread to decrease.  I also think the snow axis will shift west as the precip will be further west I bet and eastern side wide will be warmer.

It's kind of amazing how the Euro has fallen from how it used to be regarded

So pack, you're saying there's a chance still huh? :)

Honestly sounding like 'dripping snow' at best for our area---If we're lucky

Be interesting to see the ensemble mean on this one

I consider you and I, along with the western folks to be in a good spot right now.

Going to be really tough for us, even with the Euro track.  I think it will be probably back towards 85 with a narrow wet/snow band.

The eastern edge already looks to have a hard cut to it.  Just because of climo and time of year alone I expect that to shift back about 30-50miles

Exactly my thoughts. I85 and points north/west unless we get lucky and somehow don't have to fight rain and 45 degree temperatures at the onset of precipitation
