This live cam from down in town shows how ineffective salt is in this weather. This is Hwy 25w/63. TDOT had heavily pretreated and spread salt through the night.

I was surprised to find almost an inch of compaction in one of my measuring spots from last night. I didn't take any measurement at all from 4:30 am to 8am. I was at 5.5 inches in that spot, from 4:30 to 8 my cleaned off spot accumulated .75 inches, but the measuring spot actually went down to 5.25 inches.
I'm down to 14 degrees and it's back to absolutely pouring down again. Vis around 1/4th mile. The radar doesn't even look impressive but even seeing returns at all on the Plateau when the DGZ is almost to the surface, is impressive.
It's been crazy how it's just sat in place. The bands, as you guys are now getting to see, are darn fun. That's the best and worst part about ULLs. At times their banding may give an area 6 inches, and 20 miles away that area may only get an inch.
I have a spot where I measure and a spot that I clean off every three hours to measure. That will give you a good idea of your rates. And in cases where the snow is wetter than this, it will give you a better measurement of how much snow actually fell since you won't have as much compaction.
I think the 10+ projections from models that way will probably verify. The ratios are incredible so it will really stack up. I can't account for micro climates there because I don't know them like the folks who live there. But I did see that this was overperforming around Bristol at least. And Tri had 5 inches 2 hours ago.
Looks like the radar is about to light up over TellicoWx soon. It's quickly filling Blount County and extending down into Monroe County now.
I see that the Tri-Cities has 5+ already and Tys over 2. Hopefully our NE Tn crew us doing well. I hope Holston's snow hole wasn't a thing either.
This isn't quite developing the way the HRRR seems to think it should, which was down the Apps and expanding NW, but a big shield is developing over the Plateau and its heading towards the valley. The radar does look like it's itching to explode down the 75 corridor to the mountains of SE TN.
Looks like radar is filling in back to the South west too, with a solid area that may move over everyone south of 40, provided it survives the Plateau.
You may be a little too far from the radar for it to see that band well. I hope some of our Knox crew us up, looks like heavy snow sagging across them.
I can't tell which way it's going but the band that sat over me and dumped on me looks like it's made it's way down to Oak Ridge and Clinton. If it's sinking south, it should over take Knoxville soon.
I'm still not sure which way anything is moving or if it's moving at all on radar. It just seems to dance in different directions on the different sites I use.
