Fall/Winter '21-'22 General Obs

[bearman]

Snowing here in west Knox suprised to see radar continuring to feel in.

[Holston_River_Rambler]

Just woke up to get a glass of water and I have a dusting on elevated surfaces.

[John1122]

Looks like it shifted south of Campbell for now but there's a band in Scott county that looks like it will move back over. It snowed for a good 7 hours or so back home. I'd guess for now 1 to 1.5 inches fell based on returns and the fact that downtown LaFollette  down around all the pavement looks like it has an inch or so on the non-paved surfaces and roof tops. Also saw a few car driving by with what looked like around an inch on them.

Snow has nicely filled back in from all the way down towards Pikeville/Athens up to Cumberland, Roane,  North Knox, Anderson. Scott, Union, Claiborne and Campbell County,

JKL put up a SPS for widespread 1 to up to 3 inches for Bell County up to Harlan. 

If future radar is right, a nice band will move across the valley around 5-6 am. It's been trying to clear it off the Plateau since 1am and it's not gone away there, so it may be around longer than it's being shown on there for the Knox corridor.

Woke up to a light dusting on cars and elevated surfaces. Kinda surprised actually. Temp is 30.

[Carvers Gap]

Moderate to heavy dusting of snow IMBY.  

[fountainguy97]

Solid .5-.75 this morning.

 

21-22 stats: 9 events totaling 16.5" 
Basically right on the average numbers from my 3 winters of tracking. 

[John1122]

There was an inch back home this morning per my cousin. That put me at about 21 inches on the year. Not sure if there are any events left but I wouldn't be surprised if we get another chance or two. 

[John1122]

Made it home from Chattanooga. Still snow on the ground here in shady or north and east facing areas. 

[Math/Met]

I'm posting this more from a scientific standpoint because impacts should be minimal. Even though the LLJ isn't strong tonight (only in the 30 to 40kt range at 850mb over the mountains before 12z), conditions on forecast soundings are almost ideal for mountain waves late tonight and tomorrow morning. This would be a turn nothing into something scenario.  Just interested to see how windy it can get with relatively weak cross barrier winds. I'll update with obs if it materializes. 

Thursday still looks like a major event.  The stronger LLJ events like Thursday tend to hit the Smoky Mts pretty good too, in addition to Camp Creek.

[Math/Met]

Several gusts in the 50-65mph range on weather stations in the Camp Creek/Greystone area of Greene County. 

[Math/Met]

There's been a 64mph gust so far today in Camp Creek and a 78mph gust on Cove Mountain, so high winds are already verifying in the warning areas. The best opportunity for this mountain wave event is probably after 4:00pm today into early evening, as the LLJ increases over the mountains, 850mb flow backs slightly over WNC, and loss of daytime heating. Thermal profiles aren't ideal, but the amount of wind energy still provides plenty of the potential.

 

[Math/Met]

Latest update. 

83mph at Cove Mountain

70mph at Camp Creek.

[Math/Met]

I saw this on Twitter. I didn't go out there today, so I'm glad someone got some obs from the school since the tower isn't working.

 

[Shocker0]

Light snow with an unexpectedly white ground here NW of Crossville at 330am CT

 

[Holston_River_Rambler]

I have a dusting on sheltered and elevated surfaces. 

[Jed33]

Snow flurries around here now too. No dusting, but flying in the air at least.

[John1122]

Had a solid dusting here this morning. My teacher friend was mad school wasn't late because of it.

[John1122]

Had some nice snow showers this afternoon. One is underway right now.  Temp is in the upper 20s. 

[John1122]

Time lapse from the Elk Viewing Tower which is a few miles East of me as the crow flies. You can see some of the snow showers that rolled through today. One or two were pretty impressive.

[Holston_River_Rambler]

Thunder and lightning overnight. TIMs model is 30% charged. 

[nrgjeff]

I see a couple chances along and north of I-40. Still a few weeks to go up there. 

[John1122]

The squall line moving through means business with wind and driving rain. I'd say some 50+ gusts in it. 

[Holston_River_Rambler]

Lightning off in the distance to the south. 40%. 

[Holston_River_Rambler]

More lightning and thunder now. 50%

[Silas Lang]

Just heard a rumble of thunder. Got 1.54 inches of rain so far today...looking at the radar, it looks a bit more robust than the even the latest NAM . Neighbor's yard ponding up already. Going to boat to work tomorrow at this point I suppose. 

[Holston_River_Rambler]

Just got the most vivid lightning since fall. That creates a special, off run of the TIMs model. 60%. 

[John1122]

The Thunder that Holston got is moving over here now. Getting close to 2 inches of rain since last night. 

[Greyhound]

Based on the thunder / lightning we got last night, I fully expect the TIMS model to give me solid 1-2 FEET of snow in the very near future.

[nrgjeff]

My Kid reports thunder last night. Unfortunately I slept through it. 

Meanwhile every road in East Brainerd was flooded. Advisory no FF Warning. Two blocks away in Georgia had a Warning. Where was ours? Schools should have delayed 2-hours; but without the warning, decision makers did not act.

Total Failure of the Warnings system!
