    It's possible, there's a mountain to my SE that rises about 900 feet above me.
  2. John1122
    That looks like an AI version of the GFS ensemble.
  3. John1122
    Now WVLT says my area will get a dusting. So I take back everything positive I said about him.
  4. John1122
    The AI GFS has more precip futher west than the Op GFS, but less precip along the mountain counties than the Op GFS.
  5. John1122
    I believe the HRRR and RAP do, possibly the Rufus and FV3 too.
  6. John1122
    They were made available to emergency management offices.
  7. John1122
    The GFS is slightly down with totals. Basically today the low end models have went up, the high end have came down, and they are meeting in the middle.
  8. John1122
    I will also credit the WVLT met, as he said expect snow showers in the extreme cold that isn't showing up on models. This will be one of those situations where the dgz is probably around 2500 feet and up so snow will fall and it will seem to come from nothing on radar.
  9. John1122
    Whatever model wvlt used showed 4 inches for my area, 5 for Knoxville, and 6-8 east of there.
  10. John1122
    Yes.
  11. John1122
    It's just getting more into a better range for it. Also, keep in mind, most models tend to actually underestimate QPF.
  12. John1122
    Johnson City is 93 percent for over 4 and about 80 percent for oved 6.
  13. John1122
    Newest NWS graphics dramatically increased snow accumulation percentages for my area. I was 22 percent for more than 2 inches last package. I'm now near 70 percent. I had a 10 percent chance of 4 inches or more, now that's 50 percent.
  14. John1122
    The RGEM backed down by about .2 on snowfall across the area. 4.4 in Knox at 12z was 4.2 at 18z.
  15. John1122
    The ICON was a tick better. 2.8 inches at 12z is 3 inches at 18z in Knoxville for instance.
