Thunder here...and you know what might come next. TIMS models activation may be in order. Modeling is showing a system to our SE(low road) right after that cutter. The northwest trend is the real deal during late Feb. That is the time frame for the GFS's big Chatt system from the 12z Feb 5 run. Link to comment Share on other sites More sharing options...

It's funny, I remember my grandpa ranting about this when I was a kid and he seemed to predict snow better than the local mets lol 2 Link to comment Share on other sites More sharing options...
nrgjeff Posted February 10, 2022 Share Posted February 10, 2022 Saturday snow is canceled for southeast Tenn. I'm now much more interested in Thursday severe Mid South. Maybe it'll TIMS after that, haha! 3 Link to comment Share on other sites More sharing options...

dwagner88 Posted February 13, 2022 Share Posted February 13, 2022 I just signed a contract on a new house. I’m moving out to Apison. The house sits at around 950’ in elevation on the back side of White Oak Mountain. It should do much better in winter events than my current house in the city at 780’. 11 Link to comment Share on other sites More sharing options...
Carvers Gap Posted February 13, 2022 Share Posted February 13, 2022 Just looking at the CFSv2 and the EPS with the east Pac/AK block...winter is not over IMHO. That is a BIG east Pac block at the end of the EPS run. CFSv2 is quite cold looking mid-late March. I would not be surprised (to each @John1122) to see a rogue snowstorm in March. 4 Link to comment Share on other sites More sharing options...
Mr. Kevin Posted February 13, 2022 Share Posted February 13, 2022 Mid march is a month from now and by then we would possibly see ULLs develop unless we have a big trough set up. ULL are big snow producers and it's been a while since my area has seen one. 3 Link to comment Share on other sites More sharing options...
jaxjagman Posted February 14, 2022 Share Posted February 14, 2022 Someone is going to get dumped on if the long range models are right.Mid Level ridge around the Caribbean and Upper Level Ridge around the MId Atllantic.No clue about severet but hydro would suggest with this pattern some serious flood potential somewhere 1 Link to comment Share on other sites More sharing options...
Holston_River_Rambler Posted February 14, 2022 Share Posted February 14, 2022 Is it really a flood threat until janetjanet starts posting here? But yeah, the past several runs of the GFS have been showing someone getting 5"+ between the Ohio Valley and us. So far most of those runs favor the OH Valley. The EPS mean is up to around 3.5 - 4" across most of the state. I'd say 25% of the members get us over 5 - 6" and one member gives ye olden "get your waterwings and floating flamingos ready" amounts of 8 - 11 inches over eastern parts of TN. Hopefully the CFS is right and we get a break by early - mid March from this pattern that seems to be setting up. It seems to me to be like the pattern we've had, in the sense that the northern stream kept throwing energy at the Gulf, but it just never synced up with southern waves. So there were a bunch of chances for something big, but it never pulled it off. This new pattern looks like it will keep throwing energy at us in ways that would be conducive to flooding, but hopefully it doesn't sync everything up just right.

Carvers Gap Posted February 14, 2022 Share Posted February 14, 2022 And if the EPS is correct, we go from a flood pattern and back to a huge eastern PAC block which would set the stage for some cold wx in March. The GEFS is less enthused. I am a lot less bullish on a warm and early spring than I was a week ago. We are definitely going to see a warmup prior to any cold along with massive return flow and moisture. Link to comment Share on other sites More sharing options...
Carvers Gap Posted February 14, 2022 Share Posted February 14, 2022 Unless I am just looking at the wrong slides, that is a fairly significant flip by the 12z GEFS post 300 to a cooler/colder pattern and away from the torch. Link to comment Share on other sites More sharing options...
Carvers Gap Posted February 14, 2022 Share Posted February 14, 2022 Major flip on the Euro Weeklies around week 2.5. They have turned quite cold. Of course, it could be a mirage, but those are some abrupt changes that are showing up on LR modeling. At least to me, that is a pretty significant storm signal which we don't always see during March these days. I don't think winter is over. It may take a break for a couple of weeks, but that looks not warm for early March. 1 1 Link to comment Share on other sites More sharing options...
John1122 Posted February 14, 2022 Share Posted February 14, 2022 I'd like to see a big March hitter. 3-5 inchers in March used to be common here. With the upside of course for big big storms. 4 Link to comment Share on other sites More sharing options...
Carvers Gap Posted February 15, 2022 Share Posted February 15, 2022 New is left and old is right. Day 14-21. Cold is centered after March 2nd or 3rd. The overall configuration at 500 is a snowstorm look. Lots of cutters, but one of those cutters could likely force a bowling ball underneath.

If it quickly moves through the warm phases, then we may have another opportunity. I'd be fine with strong ULL. Link to comment Share on other sites More sharing options...
Holston_River_Rambler Posted February 15, 2022 Share Posted February 15, 2022 GFS has ben showing some strat. warming at the pole pretty consistently at the end of its run, for the past few cycles. More than I've seen so far this year when I've paid attention to it. If it can hold for a few more days it might have some legs. 1 Link to comment Share on other sites More sharing options...

Matthew70 Posted February 15, 2022 Share Posted February 15, 2022 For the majority outside of mountains & higher elevations. It’s most likely cold cold rains here in mid state. I will take a hard pass on those. Please. Link to comment Share on other sites More sharing options...
Math/Met Posted February 15, 2022 Share Posted February 15, 2022 Just wanted to mention that the mountain wave event for Thursday is looking very impressive. The 850mb wind chart is what you'd expect for a damaging wind event in the typical mountain wave areas. There are obviously other factors in these events (850mb wind speed and cross barrier wind direction only explain about 50% of the variability in MW wind gusts at Camp Creek), but this has many characteristics of a very strong wind storm along the mountains and foothills. 5 2 Link to comment Share on other sites More sharing options...

Carvers Gap Posted February 15, 2022 Share Posted February 15, 2022 It may or may not work out, but that is a nasty looking shot of cold showing up again on modeling this morning. I don't think lower elevations are out of the game. We just haven't seen a crazy March in a while. Even recently, I have seen light, measurable snow into April IMBY. It may well flip back warm during that time frame, but the speed of the flip on modeling could indicate significant cold relative to norms. We'll see. Still have a couple of weeks until that time frame gets here. A lot can and will change at that time. For now, we have the 0z GEFS/EPS/Euro Weeklies on board. It could bust. The much discussed 10th-20th timeframe will not verify as cold or snowy as modeled at range. 3 Link to comment Share on other sites More sharing options...

If it is going to rain, then I at least want it warmer. 2 Link to comment Share on other sites More sharing options...

Yeah, IF favorable phases coincide with strat induced blocking, chances of a storm is possible in March and a blockbuster at that. However, LATE March cuts down the odds particularly in lower eles..
