    It's like for the lead up to the this, some of the more extreme model camps the models switched sides. Last storm the NAMs were the most suppressed and east, until just before the event, but now they are the furthest north. Last time the Euro was not as consistent as the GFS, but it has consistently shown more snow where the GFS was washed out until about 36 hours ago.

    WRT to what EastKnox just posted, I think on that description (and I could def. be wrong), this section is the most significant edit: for this situation: "PVA is NOT under the vort max but is rather in the downstream area from it. Any variation in the vorticity isoline spacing, wind speed or angle the wind vectors intersect the vorticity isolines over space and time will change the advection of vorticity and will subsequently change the magnitude of PVA. In a situation where there is a vort lobe, in the downstream region of the vort lobe, some areas within the region will have greater PVA than others depending on variations in vorticity isoline spacing, wind speed and the angle of intersection between vorticity isolines and wind vectors."

    I think they're talking about the 500 mb vort (positive vorticity advection). I mean it is backing the flow out of the southwest some, but it is def. not a big wrapped up vort like the last storm: I guess it is better than nothing.

    Yeah, wrt my question earlier, the only notable enhancement to lift they mention is : "additionally think the Plateau counties up into southwest VA will also see higher amounts as they`re near the PVA which will help bring down the precipitation at a much faster rate. Further down in the valley things are much more uncertain specifically because of uncertainty in how fast the column saturates and how warm they get during the day."

    Looks familiar @John1122

    Yeah that’s what is confusing me. The models are showing some steady if not dramatic lift. Sort of an overrunning scenario. I would have thought that that would have been frontogenetic since presumably there’s a front nearby but pivotal maps don’t show much in the way of that. There’s something (we probably several things) subtle going on in different levels of the atmosphere that are lifting the moisture. No one culprit, slow but steady. Honestly I kind of like that approach more than the drama of the last storm. At least for my part of the plateau.

    Anyone want to take a stab at the lifting mechanics of this system? The 500mb vort looks strung out and weak. The jet dynamics look weak to me too. I looked at the frontogenesis maps on Pivotal and they didn't look anything like this last system. Is it that fabled lift source, isentropic upglide?

    It's a Holston River special, lol. Knoxville to Kingsport, at least in TN.

    Euro looking good for MBY this run:

    Still having some issues getting clouds to clear out sw of Knoxville, but here is a nice shot of the snow cover using visible and day phase GOES 16 imagery:

    Someone has been cutting lumber on that side of the Mountain. Made a nice overlook for me, lol. I'm not sure if it is on private land or the State forest, but it is right off the trail that climbs the mountain. Only about a 3/4 mile hike up to that clearing. The sun's over Little Brushy mountain in that one pic. I live pretty much at the base of it.

    Just about 3 miles north of my place, on Lone Mountain: Looking east from Lone Mt: Looking at Frozen Head yesterday, from Highway 62: Coalfield yesterday, looking Northeast:

    Lord have mercy, 15z SREF is resolving the shortwave as stronger run over run: Here we go again, I guess...

    Whatever was wrong with imgur is fixed now:

    Looks like the control was even further south than the OP. Having trouble uploading pics right now though.

    Here is the 850mb rel. velocity gifified: I don't know though. I'm just not very enthused by the 500mb energy: Late add: Is the QB from the transfer portal?

    Euro dug the energy for the late week system a bit more at 12z:

    On the drive in from Mossy Grove to Bearden I’d say the big winner was around Pellissippi State. Snow accumulations started to taper off around Coalfield who I’d say got 1/4”. Oliver Springs really got screwed. Nothing even on roof tops or grassy surfaces. There was at least a faint hint of a dusting on the top of the hill between Oliver Springs and Oak Ridge. As Runman said OR itself looked pretty bleak. Snow picked up again on the hill just past Oak Ride on 62 heading toward pellissippi parkway.

    A couple of pics from my area: Obligatory deck pic: Have to head into to Knoxville for a dental appointment, so will be interesting to see how it played out from here to there.
