Jan 30th-February 1st 2026 Arctic Blast/ULL Snow OBS Thread.

The “northwest flow” is almost north to south right now. This is really good for Knox County because it eliminates a lot of downsloping we get from the mountains in Morgan and Anderson County when the flow is more traditionally out of the northwest

Biggest flakes of the day starting to fall here

[GBOVolz]

Starting to pick back up

I’m just now checking in where I’ve been out for a while but man… looks like you scored pretty big. That looks like 6 to 8 inches at least on that table.

Yeah, it really started dumping, but I think we are transitioning to the more NW flow part of the storm.  

I was thinking maybe it was just the flake size getting bigger because we were warming up but no, visibility has definitely dropped. I think the models had it cutting off for our area around now and only continuing in the foothills, but I wonder with the air saturated/NW flow and temperatures dropping whether we can wring out a bit more moisture this afternoon/evening. At least enough for more mood flakes

[bearman]

Man you did great.  I ended up with around 5 inches we were just on the edge or the better rates.  You were right in the heart.

Soundings showed the possibility of this going on thru the night, but models didn't have any lift to put anything down on snow maps (that was when i was looking pre event). Haven't checked them since event started.

[Save the itchy algae!]

Currently getting the heaviest snow yet for the event.

[TellicoWx]

Near whiteout conditions here now...visibility less than 500 yards

[Math/Met]

Deck picture. It's actually a little bit sheltered based on wind direction.

Same. This is incredible

[TellicoWx]

Camera sees a little better...that's hill to hill in town square ( about 250 yards or so)

[Hurricaneguy]

8.625” Greeneville TN. Beyond thrilled!!! Still snowing too 

[WintryMixmaster]

Back to baby snowflakes but I think that 10-15 minute period added 0.1" to my total haha

[bearman]

It is ripping here now.

[TellicoWx]

My sister had drove her boys up to go sledding..they just made it back home. Said they barely made it back in 4x4 and snow drifing from the heavy rates and wind, was about 6-12" in parts of the road. She lives on one of the ridgelines outside town about 3 miles.

Got right at 4 inches in sweetwater

NW flow has kicked in. It is absolutely puking in the snow at my house, potentially the biggest flakes and the heaviest I’ve seen so far and it’s not on radar. So I’m guessing this streamer coming down through East Knox County is really laying it down since it’s being picked up by the radar.




.

I picked up another inch or so from that. It puked for about an hour, it just slowed down.

[TellicoWx]

I'm actually at a loss for words...the smallest flakes are size of goose feathers. Never seen snowflakes this large in my life.

[TellicoWx]

Hard to get on camera and it doesn't do justice to how dark it has got here

From the weather channel's radar, you can see the thin band of heavier snow that set up shop N-S through Cedar Bluff and briefly jogged west 1-2 miles and gave me that period of heavier snow (that dot it actually about 1.5 miles due north of my house)

[GBOVolz]

Big wreck on 40 just east of 640 headed west. This wreck happened about the same time one of those streamers was on radar in E Knox Co i was talking about.

Oh wow!! I hope everyone is ok. I’m gonna sit back and chill with the wifey. We actually had to reschedule our cabin because of the cleaners couldn’t make it there and I’m not sure that we’d want a Traverse Mountain Road in these conditions


.

[TellicoWx]

There's a hill there somewhere..radar has nothing on it here. All the tire tracks on the road are now covered back up.

[Wurbus]

I'm under one of these streamers in KNX and its pretty intense.

[GBOVolz]

It looks to me that the snow bands are curving towards the SW for some reason. Is this wind shear or is there a high pressure wrapping the snow around it?

I can’t get the gif to load so I tweeted the gif to link it here.

Feels like I'm in a snow globe right now

[TellicoWx]

Easily 2-3" per hr snow rates right now

What’s your estimate total you have right now?

[Scottie16]

Sun angle is something fierce.
