January 2021 Medium/Longterm Pattern Discussion.
Holston_River_Rambler replied to AMZ8990's topic in Tennessee Valley
I think some of the wishy-washy, waffly-doffly SE ridgeish looks at H5 we've been seeing in the 10 days+ range, may have to do with another Pac jet extension, triggered by a Siberian High descent and subsequent low formation in the pac (much smaller than the last one). High descent circled in black and low development circled in red: and here is what happens with the jet, notice that it gets stronger then weakens and gets more broken up: -

Overnight Ukie: Looks like, at least for now, the difference is energy over the midwest that turns the midlevel flow out of the south and mess up thermals. Ukie doesn't have it in the same place some of the other globals do: Ukie: CMC (as the most prominent example): -

It's not even finished snowing yet over NE TN, but figured this would do for us lustful snow hounds: -

It closes off an isobar in the NC foothills, perhaps indicative of a leeside mesolow. -

Looks like the 21z RAP will be nice to Eastern areas from Knoxville northeast. It's about 75% finished. -

I tried anticipating the happy hour GFS a couple of days ago, and I failed miserably. But hey, I'll always have the SREFs. On a topical note, here is a dramatic rendering of tnweathernut's PBP. (I can't take credit for it): -

Speaking of my own backyard (and probably screwing myself in the bargain), I am just SW of the 3000' Frozen Head mts and have noticed here that we can sometimes squeeze out some extra precip if it is coming in from the SSW (up the valley and then up the plateau, and then up the higher mts). Some of the hi res models have been showing something that looks like that. Not sure if it is some synoptic/ mesoscale feature or the terrain though, in terms of what the models are showing. -

Seems like y'all always get missed. Y'all deserve a Miller B that hammers you and warm noses us. (I hate Miller Bs, lol). -

Ye Olden NAM suite looks a little south at 12z. I, of course, like it, on account of the southern Morgan County dollop. It's track looks like just a classic one for TN, but with an air mass just a little too marginal for everyone. -

Looks like the RGEM has decided it doesn't like Sullivan county, but favors Washington and Carter counties: Meanwhile the 12km NAM seems to have decided to just do its own thing and keeps the snow going for most of its run from Nashville east: You be you NAM: 3km NAM has some nice bands: Here is the RAP, for fun, since we are entering its long range now: It will be interesting to see what synoptic evolution the WRF-ARW core shows when it gets in range later this evening. That core has been spitting out some big solutions on the SREFs
