    Finally figured out how to get the height of the snow line on my radar app. Looks like over the eastern TN valley it is around 2k feet and dropping steadily

    Latest HRRR hammers Clay and Knox counties, KY. 13.3 jackpot spot. I have absolutely no confidence in that sort of an amount, but that model starts to change that area over as early as 1 - 2 AM NAMs backed off sig. from their 6z runs throughout today, but the RAP seems to be coming back a bit.

    Sun setting here and temp finally starting to drop, just as clouds are rolling in, (as Dan said in the other thread). Some mid 40s on Wunderground's map near Somerset, KY

    Another Frozen Head trip. Definitely chilly above 3000'. Some cold air advection clouds too.

    Stole the idea to look for this off Jeff Piotrowski on twitter, but this a stout disturbance and lapse rates (maybe??) are helping create some convective snow in western OK. I think the disturbance if forecast to become less wound up as it moves across our area, but I wonder if any one can get some thunder 24 hours from now?

    Now the NAM, RGEM, and the RAP (show here for full snow weenie effect) have come around to some version of what it has been showing. Scratch that the 06z new HRRR looks pretty for y'all out in parts of Middle and west TN It drops the High Knob Hammer with 8 inches at LPN. All other models cut that in half. RGEM even gets into the coveted purple area in its snow precip. depiction just west of Nashville, for small window. Rooting for y'all in Nashville and SWVA and hoping i can get a surprise change over too.

    Speaking of Cross Mt. @John1122, you can really see some downsloping on satellite this afternoon. I've been getting a little bit of upslope enhanced precip here in MoCo.
  8. Holston_River_Rambler
    So we’re at the point that we have to fake punts to get 1st downs on Vandy?

    EPS member 11 loves us and wants us to be happy:

    18z 3km NAM actually tries to change y'all over before the end.
  11. Holston_River_Rambler
    Yeah, it looked like it was the heaviest precip contour on weathermodels. Really heavy precip has def. been consistent across most models.
  12. Holston_River_Rambler
    I hope it does. I guess I'm just in a bearish mood right now and won't believe it until I see it.

    I don't know what the Euro is smoking, but I'm going to drive up to Huntsville and Oneida Monday AM, to see if anything like this verifies:

    God bless the CMC, it's really trying to help some of us out.

    I’m not entirely convinced the second one has moved as far south as it will. Some of the EPS members looked better than the OP for TRI and the 6z Euro continued the trend with the energy nudging just a tad more south as it drops over the southwest. But yeah, that line somewhere between Wytheville and Marion is usually the cut off. Y’all did pretty good with something like this in Dec. 2018, right? I think my parents in Ridgefields right on the Holstein (probably one of the warmest areas in Sullivan county) got maybe 8 inches. That HP is so close to being in sync with the Low, but just a little too far ahead of it to keep everything south. hopefully as winter goes on we can get more highs to start dropping down if cold can keep building in Canada.

    Overnight ensembles in the fantasy range still look like they want to quickly sweep the trough out of the southwest, and they start to make the Pac look more favorable (GEPS least of the three though): GEPS: GEFS: EPS: In loftier realms, the strat. continues to stratify. Nothing too dramatic, but still interesting: The split at 50mb looks like it is going briefly to happen: But the last image in the above, shows it at 10mb. Still pretty wound up. The temperature maps at 10mb are more interesting to me this AM: You can see some warming over the pole, but cooler temps look to be trying to wrap back in. One thing that I don't remember noticing before is warming over the North Atlantic. As long as I've been making these strat. gifs (admittedly not very long) the heat flux for warming attempts all have come from Asia and the Bering Sea. It could be that the ever elusive -NAO, which I haven't seen materialize as long as I've been active on weatherboards, is having an effect too this year. There does seem to be some connection between the geographic location of the heat fluxes and the -AO and -NAO. I have absolutely no idea if I'm reading this correctly, but it looks to me like the two feed into one another. Reading the above gif like a graph, where the map at the botton is one axis and the hPa heights on the lefty are the other, look above Baffin Island/ Bay it almost looks like the heating that extends down from 1 hPa, to close to 50 hPa is tied to the cooling to its left, cooling that is in part an attempt to balance the larger area of heating above Siberia on the map, and extending down to about 50 hPa too. Now go back and look at the temps on the Euro's depiction of the SPV at 10 mb above, see how the warmer areas correspond. I'm hoping that there is some kind of precarious balance in this inbalance that can at least keep the SPV from dominating this winter. Further south Maritime Continent convection looks sort of healthy, but a lot of it is south of the equator, which, I believe should mute its impact. Hopefully that batch north of the equator, between 160 and 170 (with a little trailing back to 190) degrees longitude can kick it up a notch and help us out. There is some convection over the Eastern Indian Ocean that does appear to be adding some...not sure what the right word here is... momentum? maybe... to the N. Hemishpere's flow: You can also see that in this chart: You can see the bigger wave over N. Australia, just SE Darwin, and that is likely why the SOI (determined from looking at the differences between the MSLP between Darwin and Tahiti (look at all the sinking air there) is ~15 today. But again, all that OLR near Darwin is S. of the equator, so notice the arrows indicating divergent winds, all aimed S or SE. Looking at the MJO this way, you can see why it's in the COD. Conflicting, and weak, signals. Still happy with Ventrice's projections, which would show it getting more into the W. Pacific.:

    Carver's, I'm gonna have to cancel weathermodels and get weatherbell, gotta have access to Bastardi's proprietary snow algorithms for more hope, lol . I bet that mix above was all snow on weatherbell.
  19. Holston_River_Rambler
    Kinda diggin' that the Euro is digging the energy for the second storm even more than 12z, at 18z: Further south and a stronger high press seems to have been the trend with that one lately, though not sure how long that will continue.
  20. Holston_River_Rambler
    Here's the 12z EPS for you NE TN and SW VA folks. I hope it hits y'all with a good one!
  21. Holston_River_Rambler
    CPC has a new (at least to me) interactive MJO site that lets you see lagged composites from each phase for 3 month periods throughout the year: https://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/LaggedComposites/

    MRX giving us some hope this AM @John1122 "Midlevel frontogenesis ramps up between 06Z and 12Z, and QPF during this time frame are expected to be in the half to one inch range. The tricky part is how quickly temperatures will fall. The models may be underestimating the cooling that may ensue as the frontogenesis ramps up, so the forecast will knock down NBM temps a little Sunday night. This will put snow in the mountains of East TN, SW VA, and parts of the northern Cumberland Plateau. If the cooling occurs even faster, then there could be a potential for significant snow amounts in the mountains, but confidence remains low at this time." verbatim the RGEM has some very heavy precip from that forcing: Forcing: Precip: If I had a vehicle that could handle the drive in a big snow, I'd be thinking about chasing to High Knob for this one.

    18z Euro, oh Lawd:
  24. Holston_River_Rambler
    In the interests of dom (and because I saw it on the MA forum and it gave me the idea), I thought I'd look at the EPS MSLPs for the second system. More Miller Aish look. Still no guarantees it's not a rainer for people outside elevation (2500 ft. +) or SWVA and TRI, but, the more the low tracks S and E, the better for me.
  25. Holston_River_Rambler
    @Carvers Gap I like weatherbell, now lol. Those surface maps look better than what I saw at weathermodels. They had a low in Kentucky for the second system, near Louisville, transferring to the coast.
