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

Light snow here. Future radar shows the lake moisture snow arriving overnight. No idea if it actually will or not.

10.125” final Greeneville! I’m so unbelievably happy. Grateful to have cashed in big on this one. Good enough for our best snowstorm in nearly 30 years!

Dont bother submitting your reports to MRX. They have 3" as the official report for Tellico.

I feel you there. They'll put out a wildly inaccurate map at some point.

Moderate snow in Sweetwater, heaviest of the night.

Steady pixie snow here as well. Picked up about 1/4th inch in the last two hours.

Driving back from the UT game, nice snow showers on 75 S. I assumed this was lake effect snow coming from the northwest?

On the way home earlier this evening the shield of snow finally relented around 7:30. Roads were with little exception entirely white but kept traversable. Fortunately though, I didn't witness any crashes or spinouts. When I got back and went to measure snow depth was very variable anywhere from 5-9" with a mean around 6.5". Later after 10 snow showers returned and added a bit more atop. For the sake of records I will mark it as 7" although this is one of the shakiest all snow measurements I've done. As far as my memory serves this felt like the most impressive winter storm I've seen since maybe 2015. 8F and completely calm. Flurries falling.

A few satellite items of interest this morning:

Some downsloping evident:

 

Some Cumberland lake effect clouds or snow:

Pixie dust snow showers still going since about 9pm last night, picked up another 1/2inch or so but hard to tell with how much is blowing around

 

Winds finally died down a little (average of 5-8 mph versus 15-20 over the last 36 hours). Hoping the 0° windchill feels less biting than the -15° yesterday or I may have a 3 year old revolt haha

 

Roads covered and very much a gamble without chains. Anyone in the chatt area get more snow last night? Curious if school with happen tomorrow, have my doubts 

[BlunderStorm]

8F w DP of 3, visibility of 1.5 miles with pixie dust flying. Air is still.

A buddy of mine in Mt Juliet says it’s snowing there again

Where do you get your satellite images from?

There was actually a thin band that moved from NE to SW across Hamblen Co this morning. When I woke up around 6 I noticed it was snowing again. Picked up a tiny dusting on top of some cleaned off surfaces. The band slowly crawled SW and has all but broken up near the Jefferson Hamblen Co. line. I’m not sure what contributed to it other than possibly Cherokee Lake? We’ve seen that before a few times in these arctic setups.

We got a unexpected dusting this morning

[GBOVolz]

@Holston_River_Rambler or anyone tell me what this feature is that was on the nighttime satellite images? I’m trying a new way to make gifs so forgive me if this doesn’t work. lol




Here’s a screenshot of what I’m talking about.

[GBOVolz]

I got it lol

Here's a surprise. Map is way off here. I also feel like Holston got more than 1/10th of an inch as well.

Saw that earlier. Looks pretty close up here and in eastern sections. Hancock and Claiborne had Official Cocorahs Reports of 7-9 inches. So for whatever Reason they did put less Amounts in Western Area's.

It seems to match closer to their forecast map.

Some social media response to that terrible map.  This is why snowfall averages are off and it effects weather model performance.

That's what I've harped on for Year's. It goes into the MIS. Bad Spotter reporting and Official Co-op Station flawed Data , location or reporting.
