Yes, but like John said, TYS doesn’t tell the story very well, bc it’s not even in Knox Co. It was on the far southern end of where the heavier band setup, and like most airports definitely has a UHI effect. That said, the -14° was too extreme, and I did notice right at go time that the GFS corrected by warming up. However, in the places where there was 8+ inches of snow that fell, sub zero readings were common. Especially in low lying areas of those places. This included most of Knox and surrounding counties. I hit -1° at my house, but I live on a ridge overlooking Cherokee Lake. Many places away from the lake and lower elevation went lower than that into the -5 to -10 range. So, while not perfect, it wasn’t too terrible imo.

I live on the east side of Cherokee, overlooking the lake, but didn’t see any flurries. Instead just the dandruff ice crystals I remember as a kid falling after these big arctic air masses. Now, there have been some clouds though and maybe it’s possible some had flurries in them.

Seeing ice crystals float by now! Such a rare phenomenon in our area. It’s been years since I’ve seen it.

Bottomed out at -1 here it looks like. There’s been off and on high clouds and a slight breeze that has kept us from really tanking here.

I’m also at 8 here dropping 2-3 degrees an hour since about 5:30

Spoke too soon. That one was more juicy than the average clipper! Looks good.

This looks like a clipper but it’s been so long since we had one I forgot what they looked like! They used to always lay down 1-3in to the north of the low as it slid by.

Good to know about the calcium! I didn’t know that was used.

Seems like about 18° is about it for the regular brine. If they put beet juice in it, I believe they add it as long as the temp is somewhere between 5-20°. However I don’t think it’s that effective below 18°. Below that I don’t think there’s much you can do if you can’t plow it or scrape it. Just have to wait until the sun comes back out to help with it.

I was looking at that earlier. Check out the GFS. It is way colder than the cmc or the rgem! Can’t believe it will actually be that cold -14 in Knoxville and -13 at Tri. Seems about 10 degrees too cold. I guess if winds go completely calm and the sky stays completely clear it could make a run at that with this kind of deep snowpack

That’s a really common area to get a band of snow to set up after these powerhouse arctic fronts push through. In this area it is often referred to as the “Bay’s Mountain Effect”. It is not uncommon to see this terrain enhancement in that area and there is another area northwest of Sevierville that does it too. Looked like it happened this morning as well.

Now for the cold part of this storm. GFS going for sub -10F tonight in the areas of the valley that had the heaviest snow. With the coldest around Knoxville of -14!!!! MRX is saying -1 to -2 or so for most of the heavy snowpack area. If we go lower than -10 I’d be surprised, but I guess we will see. I’ve only seen lower than -10F one or two times in my life, and that wasn’t anywhere I lived at the time.

Have you hit double digits yet?

Right at 8in now! That band from Knoxville pulled right up over my area. I have literally been right on the line for the rain/sleet/snow today. Bays Mtn seems to have kept the west 1/3 of county heavy snow with little to no mixing. If I had any I don’t know when it was. Meanwhile out by I81 it was very little snow until the last hour. I think they have had about 1.5in. Such a sharp gradient in this county! I don’t ever remember seeing such a big difference in snowfall.

Heavy snow again here. Just under 6.5in now.

Absolutely ripping here!

Getting close to 6in now

Up to 4.75in now

In this area, it appears that Bays Mtn has kinda been the cutoff so far from the mix. I live in the far NW corner of Hamblen Co now at the corner of Grangier, Hamblen, and Hawkins. I’ve got a little over 4in now, but a buddy of mine out by I81 says he’s got around 2in. Hopefully the WAA will cease for all of us. It’s stayed all snow here, but I’m uncomfortably close to the line.

Closing in on 4in now wow!

It’s been snowing quite heavily for awhile! I know we’ve got to be getting close to 3.5-4in by now but I’m not sure but what that might be sleet bc of the brightbanding. I hope not.

With the snow cover it might be possible

Closing in on 3in now. Heavy snow! It’s not all that dry either. Sticking to the trees pretty well. Road is beginning to cave.

Closing in on 2in now

It’s absolutely ripping here right now!
