    I 24 at the TN/GA line starting to whiten up the roadway as well

    Monteagle:

    Snow knocking on Chattys door now...Latest RAP and HRRR shifted north some, with the 10z HRRR showing 1.9" for Chattanooga.

    First snow report along the leading edge in AL

    FFC upgraded the GA border counties to a WSW..now calling for 2"-4" for those counties. Best lift an dynamics looks to slide just to the south of Monroe/McMinn counties.

    4z HRRR slightly shifted the precip NNW..wave entering MS now

    Really hope the GFS is off its rocker for this upcoming week. It really wants to point the firehouse at the southern valley. Combine the 4"-5" being shown on the 0z op with the melting snowpack on the mountain peaks..the foothills and areas along creek/river banks would possibly be in trouble. Add in the drastic back and forth temp swings (freezing the saturated soil, then quickly thawing it on top of the rainfall) and mudslides are going to start being an issue as well.

    Think you are in a good spot..with the way the last few winters have been 1" to 2" would be a big win sadly. With the corridor of lift being so narrow..any slight shift could make a big difference either direction. Not sold that any model currently has it right.

    I would gladly cut it to a 1/10 at this point lol. Yeah it seems like it's been a bad stretch here in SE TN for awhile now. I think cutting the earlier snow totals fits well with all the combined model guidance, but mainly because the best FGEN forcing and lift passes too far south. Best outcome would be around an inch for McMinn/Monroe, with the border counties along TN/GA closer to 2".

    00z HRRR looking better in its run so far * vs the previous couple runs...still not as good as the 18z
  12. TellicoWx
    Moisture aloft is building back over N MS currently..not sure if its reaching the ground.
  13. TellicoWx
    Sounding from the ARW2 would support 10:1 even at the lowest elevations..problem with it is probably way over juiced. Sounding for 9am Sat morning over the southern valley.
  14. TellicoWx
    Looks like the ARW2..the accumulation on it starts just after daybreak Saturday morning. It will be moved out by tomorrow night.
  15. TellicoWx
    Not what you wanna see right now after the last day or so...18z GFS
  16. TellicoWx
    As for the long range...18z GFS is a nightmare for flooding for the Eastern valley.
  17. TellicoWx
    Good example of sun angle was today here...areas below 950' still has a light dusting in shade spots, areas above 950' have between 1" to 3" on the ground. Difference was the thermal layer, above 950' hovered between 32/33, while below was closer to 34/35. Sun angle had little to no effect where the thermal was closer to freezing between snow showers. Also, looks like the Skyway got hammered today. Crazy considering the Tellico River had close to a top 5 crest yesterday and a few mudslides.
  18. TellicoWx
    Yeah that was the laughable part, plus the switch over. Not saying it's not possible, but thos soundings looked fairly decent for temps to hang around 32-33 and dont see any warm nose.
  19. TellicoWx
    Only argument I can come up with of the top of my head for sun angle in the first half of Feb would be if the precip shield is more broken..in between bands if the thermal profile is borderline, then it could add just enough heat to the asphalt to cause melt. Shady areas would still stay covered for the most part. Which is what i believe they were alluding too...if models continue to show the snow, i could see them adding some accumulation but mainly on grassy surfaces in the wording. Also, this disturbance is just started appearing on short range models again. So, they are probably wanting to see if they continue the trend or if it was just a blip. Another thing is most AFDs are written close to when the 12z suite is finishing up, so the data from this morning wasn't as good for snow lovers.
  20. TellicoWx
    Honestly that whole Discussion was laughable at best...lol
  21. TellicoWx
    I wonder if all the ground moisture still around could also squeeze a little mor moisture in the very lowest levels from the evaporation taking place.
  22. TellicoWx
    Suprising, looking at all the thermals...temps are right at or below 32
  23. TellicoWx
    Agrees with the others..think the RAP was the fastest breaking out snow over N MS before sunrise.
  24. TellicoWx
    Yeah overnight into the morning hours...slight timing differences maybe in each model, but that's the general consensus
  25. TellicoWx
    RAP is the furthest north of the 4, and plays down a good bit along the TN/GA border.
