  1. 18z NAM coming in way weaker on the northern side precip shield
  2. Euro cut way down of QPF vs 0z = warmer solution/ no dynamic cooling
  3. More of a problem with using globals with this type of system..it will be very dymaic cooling driven, and it's hard for globals using 6hr windows to "see" exactly what's going on. Take McMinn Co as an example..12z actually looks better on the sounding and qpf increased from 6z, but snow accu didn't...it's hard for the model to interpret what exactly happened during the window of heaviest precip (add in this is very marginal..not much separating from light rain and big wet snowflakes). Hourly meso models may have a better feel for what happens in this setup.
  4. RGEM was close to a decent event (2" per hr rates along spine of the mountains). NAM took the heavier rates along TN/GA border...if the rates keep trending better/shield expands..a lot more of the forum could be in buisness
  5. Could the 18z GFS be a sign it's starting to step toward the Euro? Looks much better for east of Knox on that run...(1st system). Not sure it has been handling the precip rate well (dynamic cooling is going to play a big factor).
  6. Forrest Service usually shuts it down during an event (turn cars around at Indian Boundary entrance)..TDOT will put up the big road closed signs that block the road
  7. Current totals here..Mt Vernon/Belltown area 5.5" (still moderate snow), Coker Creek 6.2" (moderate snow)..Tellico 3" (flurries lol)...difference those bands make
  8. There's the energy...as it lifts NE should pop the low..Hwy 411 up the valley looks to be the divide line between 2-3" and 3"+ roughly
  9. Front just went thru Sweetwater...should be approaching Hwy 411 corridor
  10. Noticed spring city was down to 37..wind gusted close to 40 mph as arctic front came thru
  11. Skies dark enough here that it activated the street lights
  12. When you couple the dynamics/orographic lift/and models typically having a hard time "seeing" low level moisture...think a lot more of the area may bust higher after the initial thump
  13. Would have really liked to see the 0z Euro hold steady vs 18z (Knox/south)...MRX prob won't change anything as far as the advisories/warnings (except maybe move the warning a county to the west).
  14. Glancing at the 0z suite, looks like the ARW and HRRR were the only ones to get the front placement right vs current ground conditions. All the globals and NAM were slower vs reality
  15. If you loop all the 0z models at the same time frame, the LP placement is very close amongst all them...it's progressive bias is at longer range.
  16. Something to remember also about the GFS, it has a big convective feedback bias...could affect it's modeling of the precip shield
