    Go back and dig through our Nina Decembers and compare them to these ensembles at 360. This look often delivers pretty significant cold shots. HUGE grains o salt at this range, but a decent signal at range.
  2. Carvers Gap
    12z ensembles depict a fairly typical cold start to winter with sever cold over Montana bleeding southeastward into the Upper South w/ the Apps as the demarcation line. That looks has delivered some crazy cold into portions of our forum area during the past decade and a half. I suspect we see something similar again. The 12z GEFS, EPS, and GEPS all show another strong cold shot around d12-15. It is possible they are a bit ahead of things....it is also possible they are sensing a very strong cold shot. When cold is that strong on an ensemble at range....reality "could" be much colder.

    The 12z GFS continues to advertise a vey sharp change in our weather regime. Winter is on its way, folks. That is not a promise of snow, but there are certainly chances on the GFS. LR ext(weeklies) models washed out the strength of the troughs heading east. Now that the pattern is in range, it is a bit more chippy than what we saw on the Weeklies. Some STRONG amplification showing up.

    Weekend shift at WJHL is talking about upslope later next week.

    18z GFS now has the low pivoting over NE TN. That is a really cold run. Winter is on all modeling this afternoon.
  6. Carvers Gap
    Looking at ensembles and LR ensembles....winter is on our doorstep.
  7. Carvers Gap
    I think it is going to depend on how far south that energy dives. Trends often pull that energy north over time(we have seen it happen dozens of times). That may well be our set-up for snow this winter...nickel and dime stuff.
  8. Carvers Gap
    Both the 12z CMC and Euro have a decent NW flow event on tap. GFS it typically too progressive. Looks like a really good chance for 5-10" of snow for folks above 3000'. NE TN could get into the action, especially if the low doesn't trend northward(which it could). The Euro and CMC are very good setups.

    There is gonna be a thaw. Now whether that thaw is a "thaw" or spring....IDK. Just for kicks and giggles, and it isn't overly accurate at this range. That isn't a warm look.
  10. Carvers Gap
    I didn't know this until reading some of DT's stuff at wxrisk, but the operational Euro is out to 360(not just 240). And that is one cold looking run at 12z. Wow.
  11. Carvers Gap
    The 12z CMC "almost" pops an inland runner Miler A. The GFS is more of an Ohio Valley special which deepens and pushes NW flow into the area. Either way, chances are increasing that higher elevations across the Plateau and Apps are gonna see some snowfall during that timeframe. I wouldn't be surprised to see some snow showers in the valleys of E TN.

    Ya'll, I am not seeing big changes in ensembles at all. Maybe I need to go back and look more carefully. Operational runs are going to swing wildly with a potential pattern change in the works. Also, it is worth noting that storms in the 7 day range tend to disappear and then reappear. 18z GFS is a pretty robust late, fall system. We take that in a heartbeat.

    Evaporating snow chances in the Upper South are a way of life. Gotta be tough at this latitude. Welcome to the show! Let's see what becomes of it. We are kind of in that window where things get lost. But Boone probably is correct that our best chances are on northwest flow - if that. Looks like the cold front is out of sync with the GOM system. As long as it isn't 85 degrees in November anymore, I can live with that change. LOL. ...all of my wife's family is from around Canton.
  14. Carvers Gap
    Right. I think our best chance is probably a northwest flow event. Even that is not guaranteed. Given the record warmth that we have experienced during October and start of November, it is startling to see such a strong cold front bust up the heat ridge over the East.
  15. Carvers Gap
    Really, really nice upslope event on the 12z CMC.
  16. Carvers Gap
    The 18z GFS just about got it.
  17. Carvers Gap
    The 12z Euro has found the cold....that is gonna leave a mark.
  18. Carvers Gap
    The 12z GFS and CMC are threatening to drop the hammer - meaning starting winter east of the Rockies. That is a big time trough which is getting carved out. That storm is likely going to impact the hemispheric wx pattern afterwards.
  19. Carvers Gap
    The elements are there for a big phase. Timing is a hair off right now on modeling.

    Yes, I have thought for a while that something is "off" in LR ext modeling. For now, I tend to lean warm for winter on average, but as I have noted, I am not overly confident in that. If we flip cold for December, I think we generally follow La Nina climatology with January being a wild card month since it may turn out to be a weak signal. If Nina gets stronger, January is likely warm. That weak signal is trouble in LR forecasting IMO. In my thinking, Dec would be the cooler of the three winter months. January would be a "strong lean" warm. February would be warm. Modeling does seem to be coming around to December being cooler relative to the rest of winter. PDO probably still rules the roost, but we'll see. The winter where it got crazy cold right at Christmas with that Ana-front, and then winter (for eastern areas) went away. That might be a good analog. In the winter thread, I used two analogs. Dec and Feb played nice. January is one extreme or the other. I know there is a correlation between cool Novembers and colder winters. However, with AN rainfall for portions of fall and a late lasting hurricane season...something makes me think that connects to a colder winter for us. There are some mixed signals for sure, but I tend to lean warmer than average for DJF and feel confident about that. What I am not confident about is that we get a really good cold shot that makes us not remember the AN temps. Plateau (and westward) could have a different solution than what is mentioned above. The further west in the forum that one goes...the better chances for sustained winter. But, a weak La Nina will sometimes have cold shots push all of the way into the eastern valley and into the western Piedmont. I think the MJO probably drives the bus again....I don't think it will be favorable for long amounts of time as the dateline will have BN SSTs.

    There it is - again. The Holy Grail of snow tracking is having a late season, tropical storm get entrained into a strong cold front. We have had it happen twice during the past 15 years. The GFS is flirting with it...
  22. Carvers Gap
    There it is....
  23. Carvers Gap
    Still pretty fluid. I think models are sensing a pretty significant pattern change. I doubt they have anything nailed down. I like the direction today!

    This is a 30 day control map from the Euro Weeklies ext (now daily);
