Fall/Winter Banter - Football, Basketball, Snowball?
Holston_River_Rambler replied to John1122's topic in Tennessee Valley
Carver's, I'm gonna have to cancel weathermodels and get weatherbell, gotta have access to Bastardi's proprietary snow algorithms for more hope, lol . I bet that mix above was all snow on weatherbell. -

Kinda diggin' that the Euro is digging the energy for the second storm even more than 12z, at 18z: Further south and a stronger high press seems to have been the trend with that one lately, though not sure how long that will continue. -

Here's the 12z EPS for you NE TN and SW VA folks. I hope it hits y'all with a good one! -
CPC has a new (at least to me) interactive MJO site that lets you see lagged composites from each phase for 3 month periods throughout the year: https://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/LaggedComposites/

MRX giving us some hope this AM @John1122 "Midlevel frontogenesis ramps up between 06Z and 12Z, and QPF during this time frame are expected to be in the half to one inch range. The tricky part is how quickly temperatures will fall. The models may be underestimating the cooling that may ensue as the frontogenesis ramps up, so the forecast will knock down NBM temps a little Sunday night. This will put snow in the mountains of East TN, SW VA, and parts of the northern Cumberland Plateau. If the cooling occurs even faster, then there could be a potential for significant snow amounts in the mountains, but confidence remains low at this time." verbatim the RGEM has some very heavy precip from that forcing: Forcing: Precip: If I had a vehicle that could handle the drive in a big snow, I'd be thinking about chasing to High Knob for this one. -

In the interests of dom (and because I saw it on the MA forum and it gave me the idea), I thought I'd look at the EPS MSLPs for the second system. More Miller Aish look. Still no guarantees it's not a rainer for people outside elevation (2500 ft. +) or SWVA and TRI, but, the more the low tracks S and E, the better for me. -

@Carvers Gap I like weatherbell, now lol. Those surface maps look better than what I saw at weathermodels. They had a low in Kentucky for the second system, near Louisville, transferring to the coast. -

It has that wicked Miller B look to the setup. No bueno for me, but hopefully better for y'all up that way. -

I'm starting to become even more bearish than Jeff for the plateau, for the Monday deal: Even though it is coming through overnight, and even though as Carver's mentions its a great low track, it's a rainer. Hopefully the energy can get a tad more wound up and pull a wee bit more cold in. Otherwise, it might just end up being a 3000 ft + event. -

@Carvers Gap In terms of the strat, there is definitely a solid attack at it's base (look at the top of Greenland, it almost totally breaks at the bottom there) : there's just not a lot going on above that. Most models show (still this AM) it getting split at 50 mb, and the main lobe dropping in over Hudson's Bay and then trying to reconsolidate, at that pressure level. At the top though, it stays pretty stout throughout, even if it is pushed around a bit. Here's the overnight Euro OP at 10 mb: -

6z RGEM looks tasty at it's end: If it can dig a little more and separate from that N. Stream, piece it is in sync with, it would help. Otherwise it might get squished. I think if we can get a healthy vort rolling along I - 20, it may surprise with it's precip shield. But look at how differently the energy is still being handled: 6z GFS, southern stream looks similar, but a totally different depiction of the N. energy from the RGEM: 0z Euro looks more like the RGEM: and the 6z NAM just looks like as mess: Agree with y'all overnight and I think everything from the high end of Tellico's call above, to Blunderstorm's weak slider are still on the table this AM and the 0z EPS city charts show that for most areas in our forum. -

The aurora could be visible at some of our latitudes according to this site: https://www.gi.alaska.edu/monitors/aurora-forecast You have to set it to Dec. 10 though and choose North America as the region to see the visibility line at the I 40 latitude. -

I've seen fantasy Greenland blocks before, but don't think I've ever abv. normal heights over Greenland one for almost an entire run. -

Here is our disturbance, about to swing ashore in BC. Looks healthy. We'll see if the Rockies are kind to it: -

The 18z RGEM looks more 0z Euroish now: Yeah it's a meso model at the end of its run, but hey, it's happy hour. -

I kinda feel like, anemic as happy hour GFS OP was, that was the best look it has had so far: (Using COD for maximal snowage) -

CMC looks like a compromise favoring the GFS. Still some precip, but the energy is not nearly as wound up. -

Sometimes @Carvers Gap, regarding the model changes over the past week, I really do wonder how much it has to do with how they initialize tropical convection: Last week over the MC: This AM: a lot of the MC convection. is south of the equator. although there is more over the Indian Ocean -

It's wild @TellicoWx Even most GEFS members don't have much, though some have the wave. I can't tell if the new GEFS is more favorable than the old one (still available on COD: 6z Old GEFS: New GEFS: -

I really like the conversational tone of the writer who does BNA's AFD (Not a jab at other AFDs, I like em all) " I think what will be of more interest to everyone is what`s on the backside of Saturday`s system. As of right now, the white stuff is a possibility Sunday night in both of our major models. However, the euro is drastically different in evolution compared to the GFS. In fact, if the euro verifies, portions of Middle TN could see plenty of the white stuff. No, no, no. I`m not biting yet. The last several euro runs have been much different from one another and without a better sense of consistency, I`m just going to keep a chance PoP in for Sunday night`s potential wintry stuff. We`re cool and dry to start off next week, so for now, this weekend system will be the only one to deal with over the next 7 days." -

I think every model, except the GFS and GFS parallel, has some sort of wave riding the front laid down after this weekend's storm (even if they are no where near as amped as the Euro). Even the NAVGEM (God love it's little soul) Isn't there some ancient lore about if the (supposedly) progressive NAVGEM has a storm... -

Oh Lawd, I forgot Knoxville: The control looked a little more like yesterday's run, so that's why some of the eastern areas miss out on that member. -

Man, I thought for sure that was an oddball Euro run yesterday, lol. Some EPS support though (no particular order and including the 0z Mean; sorry for the speed, but giphy limited me to 1.2 seconds per frame because of the image #): -
