Same here in Union City, picked up an inch so far...coming down at a pretty good rate too. If we avoid any dry slot/dry air, we could pick up a few more inches

[ShawnEastTN]

I'm just wondering how long I'm going to have virga. Seems to have gotten to the ground quickly down Shawn's way if he already had some sleet. 

I didn't have virga very long maybe about 45 minutes, but it's still being eaten by dry air it's very very light sleet like pellets here and there.

I can now confirm a very light sleet rain mixture.

38 here and 35 across the Clinch Mountain in Gate City. If that gives you an idea of micro climates.

[McMinnWx]

Snowing here. 

[Holston_River_Rambler]

33/28. Nothing falling here yet. 

[McMinnWx]

I can’t believe it. Nothing crazy, but I’m impressed that it broke through the dry air.

Puking sleet just north of Birmingham (Cullman, Al), ground completely covered...Huntsville has transitioned to all snow in the city.

Yup. Coming down at a decent clip.

Amended: this might be sleet. It’s making too much noise when it hits.

Huntsville just added a few more counties into the warning area.

From Twitter, pic out of Cullman, AL... 

[The unknown]

It’s snowing at a pretty good clip here in Jackson Tennessee. We’ve already picked up quite a few inches. 

[Vol4Life]

Was just out in Oak Ridge about 30 minutes ago.  It was starting to sleet there

Not sure how much relevance this has for the valley. Cullman is on the west side of the plateau and has more access to low level cold air than we do.

Cullman is North of Birmingham

Yes. And west of southern portions of the plateau. There are no topographical barriers to the west blocking cold air.

It's sleeting or snowing here according to my security camera so it should be pretty close to there. I'll go outside and see if it's snow or sleet real quick

You sure, I think that’s ash lol, I see nothing

[PowellVolz]

Interesting that TWC app has changed to 1-3” of snow for Knoxville

[mempho]

Hooray!  Where have you been hoss?

Well, I had kind of a rough year, bro! My son was in sick for a long time and I had COVID on NYE and it's just been a whirlwind coming back but this is certainly lifting the spirits. What a treat this week has been!

Plateau isn't holding the cold dry air back..soundings over the valley has -10° DP overhead. It's a race between the moisture penetrating to the surface (which it already is with the sleet reports coming in from the southern valley). Also, the reason MRX kept Hamilton in a WWA and HUN is now playing catch-up in their area. Models have done a poor job reflecting how quickly the moisture is reaching the surface. Warm air advection is still hours away. 00z HRRR sounding over McMinn..
