What does the 12 km show at 72 hours?  Your previous post only showed out to 66 hours...thanks...sorry...don't have WSI graphics :)

 

 

A little ZR left for Mid GA, S and SE SC, with some (showing snow) on north side of that in central SC  and a mix around Wilmington

Word. I don't care how unreasonable that model is compared to the other models, I'll take that output and call it a night. I'm a little curious to see what's pushing the frozen precip south on that model.

 The 0Z GFS is another good run for N GA and especially NW GA/ATL area, where ~0.25" of mainly ZR falls in some areas. If anything, it may actually be a touch colder than the 18Z.This would be a pretty significant ZR event for ATL and would easily be the heaviest ZR event that wasn't immediately following a snow for many in the area since 12/2005. This could be a big mess on some roads although 0.25" shouldn't cause many power outages.

Hmm, I don't remember any ice in Dec 2005. The last ice I remember was Jan. 2005.

Larry, did you see my posts about the RPM?  I would says ***IF*** that happens to be close to right, then it could be an icy mess that way...Looked like .25" total QPF

Given the dew points on the GFS, that won't even hit the ground east of the mountains! 

It's hard to care about dew points on the GFS when theres no moisture moving in to raise them, and by that I mean no moisture even makes it over the apps hardly. If it did, dew points could possibly rise in enough time for the Piedmont and central NC to be in action.

 

Ok, well Van Denton aside, what are the chances of the dry air affecting the storm? Is there enough moisture to juice things up quickly?

 

Also, I keep reading where people say that the run is more south. Are you talking about the moisture farther south, the cold farther south or something entirely different?

 

Oh, and "stronger". Do we want it "stronger" or "weaker"? What exactly are you talking about? Sorry for all the questions, but that's how you learn, right? :unsure:

I mean, the NAM looks decent but if you look at the soundings at hour 63 if it were to be snowing on radar it wouldn't be hitting the ground due to low dew points, get out to 3 hours later it's perfect and from 66-72 you get several inches in central NC. GFS is showing an entirely different solution, this system lacking moisture and the dp staying low throughout. At least, that's how I see it.

Just for reference, 01/18/2000 is an example of a clipper that produced without a substantial vort max tracking into the Carolinas (and with a weak surface reflection)

I remember that storm. We had thundersnow here. Northern stream storms are often duds, but can be some of the best b/c they are colder by nature.

Honestly, I made that map on Plymouth a half hour ago and kept staring at it and trying to figure out what I did wrong to get a 1+ inch QPF maxima over Tenn. and finally gave up and figured I was just going batty.

 

OK, I lol at this bean.  Canadian is a pretty good snow hit for most of NC, save the SE portion of the state

and DRIER...we'll have to see if this event pans out or not...starting to become skeptical...we'll know for sure tomorrow night

RGEM has wintry weather further south than 12z.

 

Maybe a bit of sleet/tiny bit of freezing rain for CAE, but not much.  The main point is it's more South and colder.  Along with other guidance.

Generally in years, I've noticed if the GFS is dry, then it's a low QPF event.  Changes have been done to that model over recent years, and not sure if that still holds true.

850 line still barely creeps into far northern N.C.

Probably a nasty ice storm (but hopefully sleet) -- looks like .2-.5 QPF.

The Canadian actually looks pretty good.  It appears to have a decent amount of precip and has all-snow for many areas all the way out to Elizabeth City and the Northern OBX.  The Canadian was actually too warm for a lot of us at 12z, IIRC.
