    The NAM is more robust with qpf out west so far.
  2. John1122
    The NAM is much more aggressive with the precip shield early in the run, vs 12z.

    East Tennessee looks really cold through the entire HRRR. There is probably downsloping showing up along the foothills. Looks like Knoxville is 29 at the end of it's run. Other models are showing more of a warm push though.
  4. John1122
    The SREF mean is a slightly more south version of the NAM.
  5. John1122
    The Tennessee Georgia game was like the models. We started out way ahead. Then against all logic, we fell behind, now let's hope we come back at the end.
  6. John1122
    When we start out that cold we often get a front end thump before it rains. Happened several times in 2015.
  7. John1122
    The SREF is showing a NAMish solution which makes sense, as they share some DNA I believe.

    I foolishly thought we finally had a simple set up that would work for most of us. But it's Tennessee, so of course not. Models can nail snow in Texas or Oklahoma a month out. Here 6 hours out they struggle.

    There's a low in Canada over the top. When it's weaker the Euro is further north. When it's stronger, further south. Yesterday at 12z it was 986 and most of Tennessee got a good run. Today it's 981 and half of Tennessee gets blanked.

    We are approaching the "something's gotta give" stage of modeling. These tracks for the precip shield are well over 150 miles apart 36 hours before it's starting in the western areas. They'll either converge or one set is riding off the cliff into oblivion.
  11. John1122
    Not sure which is more SE the GFS or Euro.
  12. John1122
    If after all this, the upper gulf coast gets the snow storm I'll have to take a winter model watching sabbatical.
  13. John1122
    The Euro is coming in south. Memphis may get blanked if it's right.
  14. John1122
    The mean looks like that because one member dumped well into double digit inches over that area. You may or may not get rained on there due to downsloping. Hopefully not.
  15. John1122
    The CMC has us in the single digits and a monster winter storm brewing over Oklahoma and Texas at the end of it's run.
  16. John1122
    I believe in the case of the RAP there, it's still very early in the storm evolution and it should still have 12 hours or so to go with hopefully a better cold press. But after looking at some of the NAM family members, maybe not.
  17. John1122
    Yes, according to NOAA.
  18. John1122
    Yes, it looks a lot like the 3k NAM. Probably because it is essentially the 3k NAM and the HRRR wrapped in one. It runs as a hi-res deterministic model for the first, I think, 36 hours and finishes to 60 as an ensemble run.
  19. John1122
    It's the NAM upgrade coming to full time use later this year. Maybe it has the same biases the NAM does.
  20. John1122
    UKIE. 10:1 may be right here because it gets up into the lower 30s in the East. Probably a 75 mile shift SE.
  21. John1122
    The UKIE took a jump Southeast and is more in-line with the RGEM. The NAM family seems to be in the NW camp by itself now.
  22. John1122
    Looks like it was more than close!
  23. John1122
    Well maybe it won't get better. It's warm nosing like crazy and has rain in Crossville and mid-40s up the Eastern areas.
  24. John1122
    The new NAM replacement is out to 53hrs and it's a little south of the NAM but not by a ton. Its snow shield is almost right along 40 in East Tennessee and west of I-81. But it will likely be getting better for the East towards 60. Memphis gets 4 inches of snow and changes over to sleet and freezing rain on it. What a nightmare that would be, if zr gets involved.
  25. John1122
    RAP at the end of it's run.
