The only thing missing with this system was just issued…. .

I was looking at the HRRR sim earlier and towards the end of the system you could see the precip in the southern Valley up against the foothills start drifting more north back into the valley like a little wave developed or something. I haven’t looked in a while though. .

If you are not fighting temp issues, all of this moving up the valley is headed for upper ETn. It’s basically running parallel to the apps. .

Video doesn’t do justice… https://x.com/jeepvols/status/1746987812744827300?s=46&t=LVg8BRWCh1zZb6F_t95EVg .

Biggest flakes I’ve seen so far. Also… we are about to lose the sun angle while the best precipitation moves in. I’m not good at judging “rates” but I imagine what I’m getting has to be close to 1” an hour. Flakes are massive .

The radar is beautiful .

I called it a few days back. .

That stuff west of Nashville has exploded the last hour. There was a 50 mile dry slot south of Nashville but it filled in fast. .

It’s a good snow when it starts piling up in and around your vehicle wheels. .

I’m just shy of 6” now. My family took a walk on our community greenway… .

A friend of mine sent this from Ruston Louisiana. .

Man I hate that for you. Unbelievable .

Mesoscale Discussion 0069 NWS Storm Prediction Center Norman OK 1150 AM CST Mon Jan 15 2024 Areas affected...parts of middle and eastern Tennessee Concerning...Heavy snow Valid 151750Z - 152045Z SUMMARY...An area of heavier snow rates, occasionally approaching 1 inch per hour, may be maintained east-northeastward across portions of middle and eastern Tennessee through 2-4 PM CST, before gradually diminishing through early evening. DISCUSSION...A mid-level speed maximum propagating across northern Mississippi is forecast to reach the Cumberland Plateau by early evening. This still appears associated with an area of enhanced mid/upper forcing for ascent, which might be maintained through the 20-22Z time frame while overspreading portions of middle through eastern Tennessee. Thereafter, frontogenetic forcing is forecast to generally weaken across the Tennessee Valley through southern Appalachians vicinity, yielding diminishing precipitation rates. Until then, it appears that the area of enhanced lift will include upward vertical motion maximized within the favorably cold mid-level layer (centered around or above 600 mb) for large dendritic ice crystal growth. It appears this may remain strong enough to support continuing potential for occasional heavy snow rates up to around 1 inch per hour, where lower/mid tropospheric profiles are maintained at or below freezing (roughly north of the 0 C isotherm at 859 .

I think us north of Knoxville is transitioning to higher ratio snow. The radar looks about the same but the flake size is smaller but the intensity has picked up. Hopefully this continues SE towards @Reb . .

@Carvers Gap said multiple times the winners would be the ones who were just on the good side of the R/S line. He’s spot on. .

I’m so glad you are getting in on this, even if it’s 2-4”. My buddy in Cleveland has been asking me all week what’s going to happen. I told him he’s on a line where 2 or 3 miles might be the difference in all or nothing. .

Halls is Maynardville light so… lol.. my wife is from Union County. .

The moisture feed goes all the way back to Tx/La border. The bigger question is when does the whole feed start to shift SE. As long as @John1122 and our friend on the northern Plateau continues to see snow we are fine in the valley. Like John just said…. The radar doesn’t look great NW of Knoxville but the snow is there. It’s colder to the NW of Knoxville so the DGZ is lower and that area is in a radar dead zone. The radar is likely shooting over the top of the snow. .

Actually that might not be good for them. That could be, likely bright banding. When snow is in the process of melting on the way down it expands, gets bigger. When it gets bigger it shows up on radar as extremely heavy precipitation. I’ve been under those before and it could be light rain switching back and forth to fat mush flakes. .

Temp around 28 but the DP is 25. That’s should keep my temp from going up and keep me all snow right? .

TWC app has me at -6 for Wednesday morning. Don’t like that .

Dang. That usually works for me. Definitely A server issue .
