Oak Moon Upslope/ Upper Low Storm Obs
Holston_River_Rambler replied to Holston_River_Rambler's topic in Tennessee Valley
The more I look at the HRRR above, the more I think the trajectory of the Upper low has something to do with enhancing the Lake Michigan band. Hopefully that hammers someone. Maybe it backs the flow enough in the mid levels to get some extra lift??- 300 replies

Oak Moon Upslope/ Upper Low Storm Obs
Holston_River_Rambler replied to Holston_River_Rambler's topic in Tennessee Valley
I'm dry slotted for now and in the mid 30s. @BhamParker Latest HRRR shows the Lake Michigan band aimed right at Sevier county between 8 and 10 PM. It also is seeing valley areas having a tough time over coming temps as the upper low's lift swings up the eastern valley. We'll see.- 300 replies

Oak Moon Upslope/ Upper Low Storm Obs
Holston_River_Rambler replied to Holston_River_Rambler's topic in Tennessee Valley
Looks like I'm just barely gonna miss the band lifting across the N. plateau. Still rain here and 40. Wind is picking up quite a bit though. Sorry @PowellVolz missed your mention last night. There is a way to tell the elevation based on correlation coefficient radar, but I don't know. I need to figure it out though, I was asking myself the same question, lol. As y'all were talking about above overnight, will be interesting to see what happens with the upper low as it drops in to the west and creates some lift directly up the eastern valley, if the NAM, RAP, and HRRR are right. Moisture from the lakes and actual wrap around moisture is lifted at a really nice trajectory for place up the valley from Knoxville. It's the only way y'all can get orographic lift. So many mesoscale and topographic things could impact it though. John and I could get downsloped (me from Crab Orchard mts and him from Cross mountain), but that also has to work against the upper low's lift and lift up onto the plateau. I'm looking forward to watching it on radar this PM and evening to see if it develops and what it does. The IR NAM gif below shows the lift. It is the moisture @TellicoWx mentions above- 300 replies

I just peeked at the SREFs for Crossville and @Blue Moon you weren’t kidding about the mean jump lol! Like you said prolly not a good idea to bite, but fun to think about the possibilities.- 300 replies

Oak Moon Upslope/ Upper Low Storm Obs
Holston_River_Rambler replied to Holston_River_Rambler's topic in Tennessee Valley
Probably a good call lol. But the NAM is trying to do the same thing. The HRRR drops 6-7 inches over somewhere southwest of Lexington. I’m running a little cooler than forecast up here at 46 degrees and maybe that’s what is causing the models to want to change over some areas sooner? Burst of heavy snow for 45 minutes at 8 am = a win- 300 replies

I meant the MRX quote more as a chance of something earlier than the main upslope event. I'm hoping I can chase it up toward the Obed in the AM while some of the deeper moisture is still around.- 300 replies

MRX is going with a chance of some snow mixed in tomorrow AM for my area. "Rain and snow showers likely before 10am, then a chance of rain showers between 10am and 4pm, then a chance of rain and snow showers after 4pm. Cloudy, with a temperature falling to around 34 by 5pm. Northwest wind around 10 mph, with gusts as high as 20 mph. Chance of precipitation is 60%. Little or no snow accumulation expected."- 300 replies

Honestly no clue. This should be as good a chance as any to see. I've only ever been there for an upslope the one time I mentioned yesterday in banter. This seems like a better upslope opportunity. Looks like you get WSW though. Good luck!- 300 replies

3km has a pretty good ban around 8 AM. If that verifies I will go poke around to see if I can catch it in the morning: Even showing a brief change over in @Blue Moon land around 4 - 5 AM- 300 replies

I though I'd create a thread for this storm since there may be another one we are talking about in the main thread for the end of this week. I think the full moon of November is technically called the Beaver Moon, but I just couldn't bring myself to call it that.
