Euro doesn't cut and runs the low up across Central NC just like the GFS. It had a big Northern Valley dry slot earlier so totals in the East won't be what they were earlier at 12z.

Basically a near exact match of the 3k at 60.

Eastern Valley warm nose that wasn't as pronounced at 12z. Rain up to Anderson County in the eastern valley.

Maybe slightly warmer vs 12z. Major winter Storm unfolding north of 40 from the Plateau west by 1am Sunday morning.

Euro maybe 25 miles west vs 12z thru 42. See if that changes anything down the run.

The 3k, which I hadn't looked at, looks like it would pass the bottom of the mountains and not cut.

For whatever reason the individual Ens were poor for the West half of the state. Only two were big hits state wide.

He didn't take getting fired from WVLT very well.

I'm 99 percent sure that's either the NAM or the Canadian from about 36 hours ago when one run cut into Kentucky.

She apparently took it quite differently and was surprised when I said Campbell County could see 4-6 inches of heavy wet snow.

I just spoke to someone who watched WVLT weather and they were surprised that it might snow here. She said the WVLT met just said any snow that falls outside the high mountains or maybe Crossville and Jamestown wouldn't stick and there was nothing to be concerned about at all.

There's a verification link on the NBM info website.

I've noticed their predicted snowfall maps is often that. As I typed in reply to Tellico, my phone brought up an amber alert in Tellico. Hope everyone ends up okay in that down there.

That 00z will probably lead to expanded watches and is probably why Nashville and Jackson just sent out messages about winter weather being more likely.

I hope for all our sakes a Canadian solution comes to pass. That's solid for the whole forum basically. I'll take a few less inches if everyone gets more.

I'd love to see it track from Columbia to Danville Virginia.

"WHAT IS NBM? The National Blend of Models (NBM) is a nationally consistent and skillful suite of calibrated forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance. The goal of the NBM is to create a highly accurate, skillful and consistent starting point for the gridded forecast. This new way to produce NDFD grids will be helpful providing forecasters with a suite of information to use for their forecasts. The NBM is considered an important part of the efforts to evolve NWS capabilities to achieve a Weather-Ready Nation." I would guess it's the NAM/GFS family + the Euro suite.

I'm not sure what all goes into it. Jeff may know. It's where the point forecasts come from I believe.

If we can really get that low to cut up through Central North Carolina, we can make big hay on the back end.

Further south but downsloping eastern areas on the front end. Huge deform band in middle Tennessee.

GFS is warmer than the NAM through 54.

If that's real I don't even know what to say..

It seems like each model has its favorite snow hole. The Canadian models have Roane County in the cross hairs.

I assume the second shift came to work with fresh eyes.

Unfortunately, yes. We had another storm a few years ago that did that. So it's definitely on the table. We won't be in the prime NAM range until tomorrow, so I expect more changes as we go. Another shift south like the one we just had with it from 18z to 00z, and it would cut the other side of the Apps before it could get up the valley. Other models are more of a straight Miller A type track. I wouldn't give the NAM any great weight over the Euro for now.
