That Rgem run would be an all time winter storm for any month of the year. As I've said a few times, those are more likely to happen in March than any other month.
Basically followed the SREF plumes. Up over the Plateau area and Mid Tn, and around the same over the East Valley. Looks like more snow out west vs 18z as well.
We are around 24 hours out for AMZ and our west sider from this starting. Shelby is under snow returns by 8pm CST tomorrow per the HRRR.
It's coming in healthier out west than 18z.
Another 1993 flashback. WVLT met said "don't believe these big totals you're seeing shared on social media of model out puts. No way it is going to happen." Eerily reminiscent of Matt Hinkin's famous statement in 1993 about not believing the 12+ inch totals and blizzard talk being thrown about. He said 6 inches max back then.
For those asking about snow in East Tennessee in March. 2018 had several days of pretty widespread snow. There was generally 1 to 3 in East Tn and up to 3 or 4 inches in SE Kentucky.
I can't believe these extreme runs, even though I know they are very very possible in March storms. Even more likely in March storms as a matter of fact. That gfs run would be dumping 3 inches an hour here.
