February 17-18th Winter Storm Thread.

Wow, it's close to being all snow just north of me on the plateau. Maybe even for me. -

I feel like it has done well in modeling the boundary layer issues I've had with storms here vs other modeling. That said, I can't remember how far the lead time was for it nailing those,. It's still pretty far out in HRRR land right now. -

One more jump or two and the NAM will look a lot like everything else. -

NAM 3km has been a little steadier, but IMO it also made a jump south at 18z : -

850 wind trend past 6 runs too: There' certainly still rug pull potential for sure, but that trend, if not our friend, is at least friendlier. -

The 18z NAM is still the warmest model and most aggressive with the warm nose, but let's also consider the trend it has over the past 6 runs: -

Still interested to see what happens with the trailing bits of energy as the system(s) evolve over the next couple of days: -

Yeah this is the first time I've had access to soundings from some of these models and the differences between what the precip type says, what the precip type shows on the model output, and what the sounding looks like seem a little wonky. -

Look how close the above sounding is to an all snow sounding, from over my head: -

Here's how the RAP sees the precip types: Here's what it sees as the sounding around Chatt at 2 AM Thursday: It says rain, but shows mix and it is sooooo close with that forcing to being all snow. -

I wish Jack Sillin was doing what he did for that storm a few days ago, where he used RAOB data to analyze model output. That was helpful. Would be nice to see how what's left of the TPV is acting like a pseudo 50/50 low and causing confluence over NE, vs how models are seeing it. NAM seems to be playing catch up with that feature, but being the warmest model, it could still be right with eventual evolution, even if how it sees us getting there is wrong, lol. -

2/14- 2/16 Winter Storm and Arctic Cold
Holston_River_Rambler replied to WestTennWX's topic in Tennessee Valley
I think we've just had so much low level moisture hanging around the past few days, that the true arctic air, now that it is being allowed to sweep in after yesterdays storm, is wringing it out. -

It does blast the warmth in after that though. Yet the sounding over IMBY looks kinda snowy, even though it says sleet. Full saturation in the DGZ, very shallow warm nose that all that forcing and rates might mitigate. At least a sleet/snow mix I would say on this NAM run, anyway: circled area is the sounding: -
