Wintry Dec 8-10th Winter Storm

Thanks. Not sure why I bothered to ask. I knew it would be worse. Why can’t we get one of those meso high things?!

yeah its long range HRRR though. I don't really pay much attention outside 10-13hrs of hrrr. Trends at that time frame are looking solid. outside of 14hrs the HRRR is prone to make a lot of shifts and noise

18Z NAM is warmer.

Folks in Ne GA, WNC, and upstate SC are going to have a hell of a ride overnight! Heavy snow/Sleet

Writing is on the walls for RDU

That front thump of snow is going to be impressive

Peachtree City just tweeted out this link to a Brasstown Bald streaming webcam, saying that it's getting some "light wintery accumulations". Hard to tell since the Mars lander has better video quality than this thing, but judge for yourself:

We'll see how this goes, still plenty of room for Raleigh to get up to 3-4" and potentially verify the higher forecasts yesterday, but there are many good reasons I only went 1-3" in my map yesterday for both the Triangle area & Charlotte, I may keep this or bump to 2-5" depending on how we appear to be evolving relative to the short-range CAMs later this evening. Many ridiculed the NAM for getting the pattern wrong so it should simply be dismissed entirely but, models can easily be right for the wrong reasons and when I see a 60+ knot jet being modeled at the peak of the warm nose near 700 hPa coupled to about 180 degrees of deep layer veering thru the profile this brings back haunting memories of January 2017 around here. While the NAM shows all snow verbatim, it may change to sleet faster than modeled and that seems to happen more often than not lately in setups like this.



Compare the 3km NAM forecast w/ this sounding I took with my colleagues during January 2017 at NC State.
The soundings themselves are actually similar, Notice both have a 60+ knot jet ~ 700 hPa and a lot of veering in the mid-levels, the 3km NAM just doesn't have a pronounced warm nose aloft, at least not yet anyways lol.

Agreed. All models are showing a nice front end thump and then flips to something.

3km NAM just though 12z

18Z NAM is warmer.

I thought the front end thump looked better, but transitioned to mix a little faster. Looked like a wash

Looks pretty light to me.

HREF is sounding warning bells for a lot of ZR in the Upstate over to CLT, still.

Can someone post 18z nam zr maps? I can’t access it

 

[droptines35758]

Top of Old Fort mountain was white. It was 32° at the top, and 37° at the bottom.

Looks like a dusting-inch to me right now. Yeah, I'd call that light.
