Icy North I-40 event January 5th

[John1122]

Snowing quite hard now and nothing showing up on radar.  Temp has fallen to 28. 

[Carvers Gap]

Snow showers in KPT.

[Grothar of Herndon]

Light snow with temperature falling below freezing. Expecting 1-2" additional accumlation and think 1" is more realistic.

[John1122]

I've been down in town a few hours, it's snowing hard here and the ground is white. My neighbor just sent this from on the mountain. 

 

[Scottie16]

Finally starting to see bigger flakes here


.

[John1122]

The snow has now turned steady with dime sized flakes. Roads and all are covered here now. 

[Grothar of Herndon]

Temp:25

DP: 20

Light snow with a dusting so far. Wind is having most impact blowing WNW 15mph with gust 30mph. Temperature has dropped from 41F to 25F during past 4 hours. Almost a flash freeze.

[Knoxtron]

20.8 and non-stop flurries, guess we're staying in for a while 

[John1122]

Steady snow here, closing in on a very fluffy inch.

Same here. Had a dusting until a heavier band developed and dumped the last 40 minutes.

[John1122]

Just had about ten minutes of the heaviest snow of the whole backside. 

[John1122]

Still getting steady nickels and dimes. The NAM 3k had me getting 1.5 inches but I didn't believe it. 

[Reb]

Wild little streamer here coming off the Little River. Has been constantly churning for several hours. Wish I was underneath the bands!

 

 

[BlunderStorm]

As of midnight it's back down to 23 and I've recorded an additional 1.1 inches of fluffy snow. Intermittent snow showers and flurries are continuing to fall. Temperatures never exceeded 38 so the initial snowpack managed to survive the thaw and cold rain transforming into a sort of half ice half snow concrete an inch or two deep. The weekend slider however it may playout is going to have a perfect surface to start accumulating with forecast temps staying below freezing for the week.

[John1122]

It's been snowing here since noonish and I've yet to see mby have a single radar return. Earlier it was like the snow was magically appearing in Union and Anderson County down stream from here.

One of my favorite snow bands has made an appearance this morning, the Bays Mt. band:

 

It even got an MRX mention this morning's AFD:

Have extended the Winter Weather Advisory another 3 hours as north
or northwest to south southeast snow bands have set up in a few
spots. One near the Knoxville Airport and another just west of Fall
Branch Tennessee that may be coming off higher terrain features.
Fall Branch is just east of one of the higher parts of Clinch
Mountain that reaches near 3000 feet.

They call it Clinch Mt, but it is actually Chimney top, the highest peak in the Bays Mt formation. 

 

Zoomed in view:

 

 

The one Reb mentioned above is still kicking around a bit,  but is harder to figure out, but maybe it is just a good trajectory over the river:

There does seem to be some continuity with an upstream band near John?

That streamer put some school systems out this morning!  We used to call it the Twilight Zone when driving through odd snow bands on I-26 in Gray.

Looks like wind converges in the lee of the peak. Bernoulli effect both sides. Convergence zone overcomes any downslope.

Second example also looks like convergence after wind accelerates over two parallel parts of the River, then converges. Unless it's plain ol' river / reservoir effect.

Hopefully Friday we can do better the micro-events, haha!

Nah, no need to justify it.  You all have been with us form the first day that we split from the southeast forum.  Don't even think twice about it.  We aren't letting the Mid-Atlantic forum have you all.  LOL.  

Not to mention, they just don't belong there.  People like DT have zero clue how to make an intelligent snow map for SW VA and the southern Apps.  Every time I see one of his snow storm maps I find myself wishing he'd just stop including our area in them.  Either broaden your horizon and learn some microclimates outside of your bubble or stop trying.  Ok, off my soap box. 

Oh yeah, and congrats on the snow Blunder!!!  I knew you guys were golden for at least a couple of inches with that one.

[nrgjeff]

Oh my! Anytime it starts with "not to be that guy," "not to be offensive," or "I'm sorry but" then they are that guy, they are offensive, and they're not sorry. That's political roundtable toxic!

Southwest Virgnia is 110% this Region. It certainly is by weather patterns. It definitely is by culture - and that's a high compliment. It's an extension of the Great Valley (and sometimes the snow pain), the Blue Ridge, and the Cumberland Gap is still up from the Cumberland Plateau. Geography is king.

As for the topic at hand, friends west of Knoxville also had some of that snow band this morning. 

[Daniel Boone]

Picked up 1.2" overnight.

[BuCoVaWx]

Managed to pick up another inch throughout the night/morning. 5 inches total, not bad considering the amount of rain that fell with it!

[Carvers Gap]

Snowing here in Bristol(flurries).  Mountains are covered in white.  Their parking lots have been plowed recently.

[Carvers Gap]

Light snow flurries in Kingsport this morning.

[John1122]

It's actually still snowing here as well. That's the sign of a powerful winter storm, 24-36 hours of light snow in it's wake, often not seen by models. Last year was the same.

Very light snow throughout the morning today in Memphis as well.
