1-30/2-1-26 Arctic Blast, ULL Snow Event
Holston_River_Rambler replied to John1122's topic in Tennessee Valley
One other thing that has been interesting to me looking through the SPC meso page, is this ribbon of deep DGZ around the stretched out vorticity: I think there is a 3000' thick DGZ layer back in Kansas. EDIT: Oh wow, that's not in feet, it's in meters. So that's almost 10000 feet thick- 782 replies

The main cold pool is still a ways off: Still quite a bit of dynamics associated with it yet to swing through: The above isn't exactly the same, but is kind of a real time analysis of the vort. maps I and others post (example): Noticed a bit of frontogenesis too, on the SPC mesoscale page over East TN:- 782 replies

Still some dry air to overcome. And I'm guessing there are some people looking at the sounding below who have seen a model sounding, but aren't quite sure what it means, so I have put a few (hopefully) helpful tags. Above sounding is for around 8am this morning ,near Morristown, just as a site kind of in the middle of the area most likely to get snow. Red and green lines show the temperature and dewpoint respectively at any given level between the ground and the tropopause. the ground is at the bottom of the line and the tropopause is at the top. You want those two to be together or close, to get precipitation. Note that on the above sounding they are still a bit apart, especially lower down in the atmosphere. For good snow growth, you want the dewpoint and temperature to be together in the yellow zone, the dendritic growth zone (DGZ). DGZ has to do with temperature. There is additional info about the DGZ for a particular sounding in the box on the far bottom right. Temperature and saturation can effect snow dendrite type: You'll probably see some soundings on here today or have already seen some that shows a HUGE DGZ. Lastly we have Omega, called so because (I think) it is the greek letter used to denote forcing. I am not a mathemataizer, so here is a description:- 782 replies

I think at this point noon - 1 is probably a good call, but I would just watch radar and wait for the snow to reach the ground. HRRR is struggling with the radar depiction, even when it initializes with the current radar. You can see below it initializes with the current radar: But loses it in the next frames.- 782 replies
