    Holding off my run until after the 12z Euro....might be interesting.

    @Holston_River_Rambler, the UKMET looks decent...but I only have it in 12 hour increments. What do you have?
  3. Carvers Gap
    For folks who are new...Go to Tropical Tidbits, select the CMC from global models, choose 500 vort map from upper air dynamics tab, toggle to hour 66, and then use the previous run arrows to look at the last four runs. Look at the changes in that trough axis. GFS is similar but not nearly as pronounced.
  4. Carvers Gap
    The buckle/indentation on the eastern side of the 500 vort trough(you can see it around MI/IN) is not nearly as pronounced on earlier runs. That same feature is on both the GFS and CMC. That is pulling the base of that trough a bit more eastward and pulling that lee side slp northwest. That feature should give us a clue on future runs.
  5. Carvers Gap
    That is the sign of a pretty powerful signature for storm to do that. I simple neutral tilt trough will do the trick, and the system basically returns to that after it passes our longitude.

    12 CMC is west with its axis and on the eastern side of the envelop. The 500 vort map evolution is interesting. @Holston_River_Rambler was on to something earlier when he mentioned the axis of this trough needed to be watched. At 60, there is a portion of that trough that tightens up, goes slightly negative for a time(before returning to neutral). This pulls the slp north and west. Powerhouse of a system. That buckle(near MI/IN) on the approaching side of the trough is pulling the system west on both the CMC and GFS. That is why we are seeing slp pop in areas along the Big Sandy River.

    But man, the CMC just went freakin' bonkers.

    Welcome to the forum!!!

    12z GEFS at 54 Ioses the lee side low cluster. Looks like the slp may run west of the Apps or the energy to our north is being modeled stronger. My guess is the spine of the Apps is washing out the solution. Again, one more trend and this is a middle TN storm. Just depends on when the trend stops, but it has been pronounced for about four runs. Storm has sharpened which means it is less positive tilt and more neutral by the time it hits middle/east TN. 12z is on the left and 6z on the right...

    The trend on the GFS has taken the snow axis from central PA to eastern OH(during the past four runs: edit). Big changes and all westward at this point. I suspect the westward job stops during the next 1-2 runs if this follows the pattern of every other storm this winter. 48-96 hours have had big jogs westward and then revert back eastward at some point. Storm still looks health, but the angle of the storm is up for grabs right now.
  11. Carvers Gap
    Surface accumulations are significantly down on this run. The westward trend continued. I think the spine of the Apps shredded the storm. I will say...one more jog westward, and this becomes a middle TN storm (and maybe major) on the GFS. The synoptics still look good, but a low directly over the apps just messes with dynamics to no end. My expectations are low for MBY on this one.
  12. Carvers Gap
    GFS is going to be a paste job for some.
  13. Carvers Gap
    Through 42 hours, the GFS looks sharper and follows the trend of short range modeling.
  14. Carvers Gap
    12z GFS is rolling.
  15. Carvers Gap
    That is a nasty looking storm on the Euro after 200.
  16. Carvers Gap
    12z RGEM has a similar trend NW. In this scenario, NE TN gets a good thump, but if you look at the snow totals for this storm, you can seen the axis really sharpen and back west a bit. So looks like the short range "cone" is the spine of the Apps to just around Nashville. Prior, this had stopped at the Plateau. NE TN is on the easter envelope of this now - but a good run nonetheless but trends do matter at this stage - not a huge fan of trends right now for MBY. That said, the storm is still there...just backing west a bit. So, the likelihood of somebody getting snow on Christmas Eve is still there with chances for somebody in our forum area(to see a decent thump of snow) increasing at this point.
  17. Carvers Gap
    @John1122 and some other posters in that region are gurus for your micro-climate. I will let them answer your question in detail on that. They are way more knowledgeable about the northern Plateau than I am. But yeah, generally, your chances look decent IMHO.
  18. Carvers Gap
    1-2. We deal with a significant heat island here and are right on the river, so our elevation is a bit lower than Bristol or JC.
  19. Carvers Gap
    I would be liking my chances right now if on the easter side of the Plateau.
  20. Carvers Gap
    3K NAM looks a little more robust for E TN valley locations...not a fan of that trend for MBY but will benefit folks to my west. Let's see where modeling goes...trend overnight have been a slightly westward jog of the slp. Storm may well be a powerhouse. Problem for those of us in E TN, the stronger this gets...the more it could wind-up and shift west. Again, the NAM has issues with being overly amped past 48, so lets see what the models on the east side of the envelope do...RGEM and GFS operational. The Euro at 6z was popping a low over NE TN.
  21. Carvers Gap
    And welcome aboard!!!!
  22. Carvers Gap
    Probably a wise move right now. If the 12k NAM(which is iffy at best at this range) is correct, they may be too high over NE TN. So, going conservative is wise. They can always up totals. I think that is just a heads-up for people traveling.
  23. Carvers Gap
    12z NAM basically blanks E TN valley locations.
  24. Carvers Gap
    If you live in NE TN(really all of E TN), not a trend you want to see from the NAM. Now, it is the NAM past 48 hours and it has a problem with over-amping systems. The slp is stronger with the NAM by several millibars. That in turn sharpens the storm and changes the angle into the region. Snow axis moved about 200 mi west in KY from eastern KY to middle KY.
