The 00z HRRR just ran the low straight into the mountains and never transferred to the coast. When it ended, it was a 997 low sitting in West Virginia. It's the HRRR at long range....but don't think I've ever seen a low do that before. Needless to say, it wasn't a good run.
I just don't want a WSW for Knox county issued from MRX. If that happens, 99% chance we aren't getting Winter storm warning totals. If they decide to go with a special weather statement or WWA, decent chance it over performs in Knox.
My money is on what CMC is showing here. Snow everywhere but the valley with that warm nose. I'll be happy with my 1-2 slushy accumulation and enjoy everyone else's pictures.
We have 2 camps at this moment. GFS/CMC is showing the low meandering across TN while it transfers to NC/VA and most everyone in TN gets mostly rain. The other scenario is Euro/UKmet/GEFS showing the low further south into mid-Mississippi and then transferring to around Myrtle Beach and brings all types of wintry precip from Memphis to Kingsport across the state.

I'll say there are more big dogs for East TN on the GEFS that I thought there was going to be. I feel like this system is truly a boom or bust system though and will likely be more of a bust for most of us.
