Historic Christmas Cold & maybe snow?! Dec 23rd-30th
John1122 replied to Wurbus's topic in Tennessee Valley
That GFS run was similar to the wild Euro run either yesterday or day before. -
Historic Christmas Cold & maybe snow?! Dec 23rd-30th
John1122 replied to Wurbus's topic in Tennessee Valley
I just read a post, maybe even by you, from the March storm as it approached, that the Euro had just completely caved to the GFS. That said, this one is still early in the game regarding the storm. Extreme cold seems nearly unavoidable but it would be tempered with snow vs without snow. There's still very often major model disagreement inside 90 hours over the last few years. -

We will see where it ends up and who caves, but the Euro is erratic to say the least, right now. -

It's odd to watch these models cutting storms straight towards the heart of a big H over Eastern Canada then they get caught in Northern Michigan and sit and spin because they can't go any further.- 582 replies

It's liable to be way off but it did this in March this year when the Euro was reluctant to get on board at this range.- 582 replies

I suspect the Euro may have the issue the cpc noted several days ago where models weren't allowing storms to feel blocking properly. They noted that storms should be pushed further south than they were being modeled. It doesn't make a ton of sense to see a storm heading for Michigan with a massive -NAO in place.- 582 replies

The Euro keeps firing blanks. It did that often with last years events as well before finally catching up. Hopefully that's the case here.- 582 replies

Seems like there was a big snow event just to my NW and parts of Kentucky that got the snow were in the -15 to -20 range. I got to -2 or -3 4 times in a 10 day period. When that cold hit everything was shunted to the deep south/southeast coast.- 582 replies

A met on Southern who has been designing his own model posted his latest run and it was a doozy. Unlikely to happen but his model showed a power house Miller A with widespread 12-15 inch totals across basically the same areas that got heavy snow in March. Slightly lesser totals far Eastern areas but still 6+ inches there. No idea what goes into his house model but it would be glorious if it were some how correct.- 582 replies

I was below freezing from around Christmas until January 10th. Had some highs in the 10s and lows below 0, which is maybe only one of three times I remember that without at least an inch of snow on the ground.- 582 replies

I was thinking 17-18 was cold to the coast and the deep south got snow while we were mostly dry but frigid.- 582 replies

17-18 was our last monster cold wave. Unfortunately it was also arctic dry. Had we managed snow cover we'd have seen -10s that time. Still, we were two weeks below freezing and the creek had ice 8 inches thick here. Late December and early January cold waves are different due to that low sun angle. When they hit, we get a lot of frozen creeks and ponds. Hopefully we get snow with this one.- 582 replies

John1122 replied to Carvers Gap's topic in Tennessee Valley
The ridge out west will be all the difference for our area, it needs to be a little taller than it was on the Euro to get a solution more like the GFS from 12z. The consensus now is cold, and a system that has a great deal of spread in it's evolution. So right now I'd feel very comfortable saying it's going to get very cold. Somewhat comfortable saying that there will at least be flakes in the air somewhere in our region as we head towards Christmas week, but very unsure about anything beyond that.- 582 replies

I think we will get it in this pattern. It's rare to get such a potent front to move through that doesn't at least bring some snow with it.- 582 replies

Really nice clipper pass on the 0z for most of the area. Reminds me of the old Siberian express systems that would dump 2-4 inches of snow and rush in extreme cold behind it. The Canadian is almost as snowy, but even colder than the GFS through 210.- 582 replies

Poured all day here as well. There was some thunder around 5pm this evening too.

The Euro is still not where we'd like it to be, but it's slow to get on board over the last few years, on systems like this. We've had a few nice anafrontal events including the 2020 Christmas eve snow, that the GFS spotted first.- 582 replies

The 12z suite is coming in cold and the snow was back to some extent on the GFS and the Canadian is all in.- 582 replies

The GFS is so extreme that there's a late run snow event where New Orleans is too far north to be in the heavy snow axis. Mobile and Panama City do really well.- 582 replies

The Canadian has the GFS rain to snow idea from 18z. Also very cold, if not quite as cold as the GFS. Curious to see now if the Euro joins the cold part or keeps it's warmer idea from 12z that lacked ensemble support from the EPS.- 582 replies

0z GFS now has a clipper ushering in the frigidity on December 21st. Then it gets frigid and upslope piles up on the plateau and mountains, Even not showing up on the p-type maps the snowfall totals go up.- 582 replies

18z looks just like modeling did for the 2020 Christmas eve snow event. Those strips of heavier snow in an anafrontal situation. I've noticed it often models anafrontal snow that way but we tend to all get closer to equal amounts when it happens.- 582 replies
