Visibility down to about 1/4th mile now. Flakes still dimes and nickels. Looking at cams it's snowing in Cumberland and maybe Roane but it doesn't look like it is yet on the west Knoxville cams. Should start soon if it isn't, I'd think.
Snow has started here. Very little virga at all. Maybe 10 minutes of it. Still very light but flakes are reaching the ground. 2 hours early vs MRX timing.
The fire hose that Powell was talking about it portrayed on in ICON laying down 4 to 5 inches in a band about three counties across from out AMZ's way across Murfreesboro, along the Plateau and into SE KY and SW VA.
The models that showed a good thump around Clarksville and St Louis are so far winning vs the drier models that choked off totals out that way.
Fwiw the 0z Gem/Rgem/GFS are very close to what is ground reality that way and they are upping totals this way. The GEM just put 3.5 inches into North Knox and 2.5-3 inches along and south of 40.
The RGEM is similar with a little bonus area of 4 inches around Roane Co.
The GFS is 2.5 inches or so along 40 and also slipped a little heavier area around Roane and Loudon co.
None of the mixing issues around the foothills really either.
Hopefully they don't all school the Euro west of here then lose to the Euro here.
You'll usually see some virga there, as it's higher moisture. When the DGZ lowers is when you have the most trouble seeing snow on radar. But eastern Fentress/Western Scott is usually tough under any circumstances.
