Fall/Winter Banter - Football, Basketball, Snowball?
Carvers Gap replied to John1122's topic in Tennessee Valley
Great start and then coasted home....but glad to have Tennessee basketball back. -
Fall/Winter Banter - Football, Basketball, Snowball?
Carvers Gap replied to John1122's topic in Tennessee Valley
John has it posted in the main thread. Great track. ICON had something similar. -
I think we are 37 as well. With that light breeze, still chilly. I have to go running later...just trying to wait for it to warm-up a hair.

Man, I really despise lows in the GL regions when tracking storms...they really screw-up all kings to potential. -

That threat is not too far into the future. The 12z CMC and ICON especially have some threats. ICON is super similar to the Euro. Seems to be an wide range of solutions right after 120 with some of those begin wintry. -

MBY has zip as well. Hey, it can only trend better. -

The 12z GEFS and GEPS continue a very quick pivot of the pattern after d10. The 12z GEFS(very late in the run so beware) has a ridge in the West and a block over Greenland. GEPS has something similar with more ridging along the EC. These are fairly significant changes compared to the what has been advertised for many days. -
Temp is 34 in Kingsport with a slight breeze. WC is probably below 32. Pretty raw day.

Biggest thing I notice is that it is a real pain to get it to snow in Tennessee prior to the 15th of December. We have seen some early season, low-elevation snows during recent years...but really as a kid I never really expected it to snow until around or just after Christmas. Getting some great tracks with marginal or no cold. If we can keep that track(or have it re-develop) later this month or in early January, we would likely be in business. I would not rule out accumulating snow north of I-40 during the next couple of weeks across the forum area. Someone would have to thread the needle, but anytime a storm goes "under" us in terms of latitude during the winter months, it probably should be watched. -

12z suite rolling. Taking a quick break from the virtual school grind.... Looks like the GFS, ICON, and CMC have low-road storm threats. The ICON(nice middle and west snow) and CMC both have something between 120-140h. GFS looks slightly too progressive. VERY active pattern - mostly rainers but some mix/snow stuff. -

Major changes on the GEFS extended for early January. Fairly massive shift. This is the daily run of the extended GEFS which rolls about this time each evening for the model suite I subscribe to. @Holston_River_Rambler, do you have access to it? Check that...shift begins Dec 28 -
Spitting some salt and pepper size flakes here. Had some flurries and very light snow showers for about an hour or so. You can see the banding of those on the RadarScope image below.

Yeah, modeling seems to be feeling the presence of the NAO for sure. I am not ready to buy that feature quite yet as there has been a wicked bias towards that. However, we are long over due for a -NAO. Seems lately that the disruption of the SPV and -NAO go hand in hand...but seems like the NAO flashes and then disappears. So, we will see what happens. I was honestly surprised the Weeklies didn't look worse at 500. If they had run from 12z, likely would have looked even better. Again, lots of cutters and maybe some storms passing underneath if the block verifies. Seems like when the NAO shows up, it is often a fixture for most of winter...but ready to see it verify for a week or two before really believing staying power. IF(stress) that is a real feature, that should begin to create a feed(with the unfavorable PAC) into the norther Rockies which bleeds eastward at times. Not an exceptional winter pattern, but probably has the potential to be better than the last few winters. AN temps in January(provided they are slightly AN), can do the trick if timing is right. The NAO would provide for more confluence along the EC. Anyway, way out there...but worth a mention. Hey, it is early Dec...most years(prior to the last five winters) I really wouldn't expect winter wx until later this month or Jan. -

The Weeklies seem to imply that the cold is going to push after initially going West. And that is extremely cold air in Alaska. When operationals start to bounce around usually some very cold air in NA...noticed both of those characteristics at 12z today. -

I personally didn't think the Euro Weeklies looked terrible for 850temps(I never uses its surface temps...terrible warm bias) and 500 maps. The 12z EPS was quite a bit different. In the past few runs it has eliminated the ridging under neath and was quite close to opening the door for the air mass in AK to drop into the nation's mid-section. Will try to post more later. -

12z Euro continues with a progressive pattern of cutters and low road lows(which lack cold). What is actually cool about that run is that it has the AK to SE trough(albeit temporary) which ensembles have struggled with for about a week. Some bitterly cold air in north/central Canada along the eastern shores of Hudson Bay. -
That's pretty hilarious. I see that we have a few who speak our local wx microclimate dialect.

Carvers Gap replied to John1122's topic in Tennessee Valley
Whew. Good luck making heads or tails out of any of those runs - GEM or GFS at 12z. Lots of cutters. Maybe one or two taking the low road with cold air lacking. When models goes haywire like that, makes me wonder if we are about to see some very cold air invaded the lower 48, maybe just after the day14-16 window(basically just outside of modeling's range). Lots of chaos in those two model runs. -

Carvers Gap replied to John1122's topic in Tennessee Valley
I have to be honest...I am not seeing a locked-in pattern on the operational runs at all. Just looks like a pattern with a lot of variability. -
Inside joke for the rest of the TRI Kingsport crew. If you know what we are talking about, discuss let's not...we all need our relatives still working. LOL...downsloping is just one of the problems we have to overcome.

LOL. You know we are going to be last in Kingsport and you know why!

About 300, the 18z GEFS has a ridge now out West. Likely temporary, but illustrates the uncertainty after the 18th. -

Also in the "evening" news from the MA forum(above info was from there as well), the 18z GFS does put the hammer on the SPV. Bout all I got for now. -

DT is mentioning a fairly significant weakening of the La Nina (maybe in the Euro sesaononals) over the next six months. Not sure that helps us at this latitude as it might not help until March. That said, I will take a weakening Nina vs a strengthening one. It is very important to note that most ensembles, monthly model runs, and seasonal models missed the December cold snap. I will post the Euro seasonal for December if I get a chance later. That said, if the Euro is going to miss...Nov/Dec are usually excellent candidates. -

That is kind of my thinking. Maybe get some truly cold air into the Rockies and let it bleed eastward at times.
