Wintry January 3rd-6th, 2018 Winter Storm The ARCC/Xtreme Weather Special

From met Chris Simmons on Facebook. I'll take it.

Nice he has me for best of heaviest snow
 
New Swiss model for Virginia has 12-16" over me

Seriously if the RGEM's upper air dynamics are correct, there will be an area of 12-18 inches in NC and Virginia. Super dynamic storm. Would love to be in your location right now. Would not be surprised if you get thundersnow. In fact, I would expect it if the RGEM verifies.

How strong will the winds be, yeah I get to plow it too, can't wait to make this money and track and enjoy the snow
 
The 6z GEFS made some significant improvements. The low placement and precip shield has been shifted about 50 miles west. The biggest net gain was in SE GA, FL, and southern SC. Those significant improvements at that short lead time with the ensembles (and the operational too) makes me think that there will be more corrections further upstream on the next run. Here are a couple of images from the GEFS:

Globals at this hour? who hugs those?
I think we get hung up on EVERYTHING until all the models come to a general consensus (or the event is over). Unfortunately, the models will have some significant differences until the bitter end. Makes this a fun, and sometimes exasperating, hobby!
 
Me, Frosty and lots of others in WNC, Ala, Miss, Tenn and likely even NW Ga are pretty much out of this one but I hope those down East/South will get some good numbers

Matthew East said this regarding the comparison to the Jan 2000 storm.

Not going to get the air of of the Deep South moisture injection that one had, most likely.

He did say it's possible the snow could get as far west as the Triad and Charlotte.
 
Do you know much about the WRF-ARW2? From what I can find, it sounds like it's recent performance may be decent but I honestly know nothing about it. In my opinion, I like it's depiction of the surface low consolidating faster (although I think it is too far east and probably too weak) and the precipitation shield the best of all the runs I've seen so far.

Hmm, I'm not sure either but I would agree that's a fairly realistic depiction of what could happen here, snow possible getting as far west as the Triad and Charlotte, with the core of snow over US-1 &/or I-95 and a lot of mixing issues east of I-95... In general the synoptics seem to favor a slightly dampened version of January 2000 if anything, but I'd feel really good about this storm if I was in Fayetteville, Goldsboro-Wilson, Roanoke Rapids, & Raleigh-Durham right now... The Triangle was on the eastern edge of the heaviest snows in January 2000 so a little E or SE shift won't hurt us
 
I don't know really what to think this morning. You have the globals lock and step with one another and refusing to budge but then this morning having the RGEM on board with the NAM is promising. I have winter storm watches one County to my East and rah going with 1-2 here. Going to be fun to watch today especially the location and strength of our short waves and I mean really we are less than 24 hours away from things popping off down south

Has a nice heavy snow band over my area
