The episode as NWS OHX wrote it up.
As 2024 came to an end, precipitation totals for about the western half of Middle TN finished near to above normal for the year. As such, December 2024 saw drought improvement across this area. However, precipitation deficits continued to grow across southern Middle TN as well as along the Cumberland Plateau. Crossville's end of year precipitation total was 46.94 inches which was nearly 11 inches below normal for the year. This meant that drought conditions persisted or even worsened in this area. By the end of December, about 31 percent of the area was in at least severe drought with about 12 percent of this area in extreme drought.

Area Forecast Discussion National Weather Service Nashville TN 1047 PM CST Sat Nov 30 2024 ...New AVIATION... .UPDATE... Issued at 831 PM CST Sat Nov 30 2024 A long wave trough is set up over the eastern US with a short wave passing to our north. We are seeing some light radar returns from this over our area with plenty of cold air in place. Our dew point depressions are quite large though (10+ degrees) and the 00z OHX sounding shows plenty of dry air in the low levels. Most of this activity will not reach the ground but can't rule out a few flurries into the early overnight. No accumulation or travel issues. Cloud cover will stick around tonight and that will keep things warmer than last night but it will still be cold with lows in the mid 20s to lower 30s. Cloud cover will linger tomorrow morning but we should start to see some clearing in the afternoon. && .SHORT TERM... (Rest of today through Sunday) Issued at 1137 AM CST Sat Nov 30 2024 Temperatures are warming up nicely this morning considering most got down into low 20s! Current observations show a range of 32 to 40 degrees. Snow is falling across central Missouri right now and the movement is generally ESE. The latest NBM has brought a touch higher PoP chances (20%) across the TN/KY border starting this afternoon. Given the southerly component of the system's movement, I think that's reasonable to maintain for today's forecast. It will still likely be snow flurries falling mainly across areas north of I-40. Temperatures will be too warm this afternoon for any impacts. Our 12Z sounding also showed a considerable amount of dry air in the snow growth region (-12 C to -17 C), so we'll need things to moisten up a lot more if we even want to see flurries. Clouds will continue to increase in coverage through the day and this will keep lows tonight a bit "warmer" than last night: mid 20s along the Plateau and 29-32 across the rest of the area. Regardless, still at or below freezing for almost everyone. Sunday will feature clearing skies and an increasing northwesterly wind, setting the stage for another very cold night across middle Tennessee with lows in the teens again along the Plateau and low to mid 20s across the rest of the area. && .LONG TERM... (Sunday Night through next Saturday) Issued at 1137 AM CST Sat Nov 30 2024 Upper-level flow will remain out of the northwest, helping infuse a series of mostly dry cold front across the area through the week. Deterministic models show quite the spread in precip chances and with so much uncertainty, not much change made to the extended. Cold and mostly dry is the big picture right now, though. It does look like we'll see daytime temperatures reach back into the upper 40s to low 50s next Wednesday and Thursday, but another cold front will push temps back down into the low 40s by Friday. && .AVIATION... (06Z TAFS) Issued at 1045 PM CST Sat Nov 30 2024 Largely VFR conditions over the next 24 hrs. Some snow flurries are moving through the area tonight, but they will not have any significant impact vsbys. Light and variable winds tonight, becoming NW less than 10kts after 12z. && .PRELIMINARY POINT TEMPS/POPS...
