Synoptic WF appears to have made it as far north as I-80/88; however, outflow farther south in central Illinois is obvious on the surface chart (10am Central Time). I figure the rouge cells ahead advertised on some CAMs will go on that OFB. Given how sharp the WF is up north, I'd favor the OFB. Note I have a strong personal bias toward OFB. Still could be chaser's choice. I'm also not in the field today; so, with a virtual chase I can afford to take forecast risks. Still I have to like 1-2 cells east of where the OFB intersects the Pacific front / quasi-DL. Good luck, and be safe!

Late summer drought (perhaps flash repeat) would not shock me. Risk of sooner, but depends on if SER is dirty or clean. Until then pretty wet, yuck!

Hopefully the -NAO is a joke too. Might as well get on with spring. Let the SER give us some sun and Vitamin D! Long range I have to favor a persistent SER. TNI might get backwards for severe early / SER late spring. However, the broad forcing is already acting Nina. So after electric load goes on holiday, maybe utilities can make some money back this summer. HOT and HUMID - Dry heat is off the table after all this rain.

Big changes since Sunday. Instead of Ohio River Valley jungle, we now have an outflow boundary in North Alabama and just south of KCHA. Still plenty of failure modes. A. Rain-out B. Veered off C. Capped (too little too late) D. Combo of 2-3 above E. Rather watch sports reruns Early season is prone to failures, which is of course good for the general public. That said I figure ENH is incoming. Obviously if something is close to KCHA I'll take a look. No chase greater than 2 hours though; so, I won't be visiting the chasable northwest Bama area today.

We got throttled March 2012. I've nothing much on this week. Veered off trash. Only turning is in the Ohio River Valley jungle. Back to NCAA Basketball reruns!

I expect Tuesday will get an Outlook on Saturday morning or soon after. Euro remained consistent if not stronger. LLJ is a touch veered, but not like the last two systems. It's fortunately not backed like Super Tuesday either. Upper level winds are a given. Low level theta E (temps/humidity) will be a question. Even with all those caveats, if the Euro holds, one has to think Tuesday gets a 15%.

Be safe @Calderon and thank you for your service!

A less smug tone is appreciated next time. Thank you. Holston you are a better person than me, lol!

The Midwest can have it. Dixie had enough heartache for the season.

Judging by my Twitter feed on Friday, storm chasers are out as usual. They are being careful at gas stations and rest stops. Bringing their own paper towels, wipes and hand sanitizer. Air fare will be cheap to the Plains. Airlines are offering no change fees! Do you know what that means? You don't have to know the exact days when you book. Gasoline is cheap too. Seriously though, I'm not even thinking about travel until we see how this plays out for a few more weeks. Dixie local? No thanks as in any year. Critical Federal Agencies have plans, but I will defer to an NWS Met for more on that. NWS and TV Mets are very dedicated to saving lives in any circumstance.

With an MD in the house you already know, he is perfectly safe to drive home solo (COVID-19 independent of the activity of driving). Bring paper towels with, for restrooms and door handles. Educated guess is Alabama is awaiting test kits. No policy/politics in here, but Bama has finally confirmed at least one as of this writing. Highest Middle Tenn confirmed is in affluent suburbs. Do they have their own test kits independent of the CDC? My guess the risk is equal both places (very low). That said... Informed people I know are practicing social distancing. Work recommends avoiding groups of 10+. I've heard sharply conflicting thoughts from the two MDs I know personally. However the tie was broken when Galen Medical released an article: This is No Snow Day. Galen says don't even let kids play with their friends much. Tough for solo kids w/o siblings. Keep having fun as a single nuclear family unit only. I was thinking, wow really! Galen and Church (online only now) both make the point. We do not act in fear. We act out of love and consideration for others. Elderly and vulnerable need us to collectively stay healthy in order to protect them (much as we can). Medical sector needs us to slow down this thing - spread out the cases - which we know are inevitable. Spread out over several months will be easier to treat than all at once. So we are keeping to ourselves, except to buy perishables. Couple weeks ago we took care of non-perishables for a while. We go out to jog and play soccer or shoot hoops. School is remote by video app. Work in shifts. Probably have several movie marathons and books in our immediate future. It's different, but we'll manage. Keep your faith. And hey, now we are all ready for severe weather season too!

Link between COVID-19 and weather. Storm chasers enjoy cheap air fare to the Plains. No 14 hour drive! Oh wait, the actual storm chasing days. I forgot about that.

In an ever changing World of uncertainty, the European weekly charts offer a dose of stability but not-so Southern Comfort... Warm and Wet! Go figure. In other news KU is ranked #1 with no March Madness. I guess hang the National Championship banner at Allen Field House.

I got distracted watching stocks, lol! But yes, we have a severe weather problem in Tennessee tonight. So the models all have Missouri Boot Heel convection going into Kentucky. All clear? Hell no! Let's do some meteorology. First of all it's not moving northeast. It's moving due east. That'll anchor the boundary farther south than progged. Gee, that never happens. I am hoping the short-wave ejection will push the boundary to the TN/KY border. If not it's in danger of hanging up near I-40. Frankly breaks my heart to type this. Sometimes we science. Sometimes we pray. Anyway, the 850/925 mb charts look more veered than Super Tuesday. Do not expect a repeat. Still, just strong storms disrupt recovery. Psychological damage of just general thunderstorms can't be ignored. Shear will be worse up in Kentucky (or wherever the boundary settles out). Not Super Tuesday, but not a good night either.

Please do. Your local utility will like you. Thoughts are my own, lol! If we can keep air fare low through next winter, I see some Rocky Mountain skiing in the forecast!

Guess we can already go with another blowtorch winter 2020-21. Maybe the SER will be such a beast it keeps severe Midwest and Plains. Flash drought coming to a place near you.

Yes @Calderon is absolutely correct! @PowellVolz that's not a TDS. That is lofted debris carried into the forward flank. Also a sign of a violent tornado. Sure enough OHX finds EF-4 damage. Though the lofted debris signature didn't last as long, it has similarities to the Kansas City tornado last May. Middle Tennessee tornado itself might have lasted longer than the KC one. Have to look back at all that. At any rate, this Tennessee tornado was historical.

European weekly charts are ugly for severe wx the next few weeks. Great Lakes Ridge with Gulf Coast underbelly is replaced with more traditional East Coast ridge. +AO and -PNA spell more Dixie Alley trouble. I'm not rooting for this. Rather postpone to May Plains.

Low CAPE high shear events happen. Wait! This was not exactly that... I'm watching KPAH get the hail treatment about 5pm Monday. Back of my mind I know it's westerly flow aloft over a boundary - but a little early in the season for that set-up. Text my buddy a boundary rider is going off on PAH, but don't think too much about it. Cell weakens, and I start gearing up for Big Monday college basketball on ESPN. Wake up Super Tuesday to Middle Tennessee super tragedy on the news. WTF? Going back to Monday afternoon shear was never in question. I've written here many times, look for westerly flow aloft instead of that SSW flow junk. Nearly 90 degrees of turning was noted. 850 was a little veered, but upstream was deep moisture - count it as backed in Dixie. 925 mb was straight south and both increased going overnight - all forecast ahead of time! Surface of course had the notorious boundary related SRH. CAPE and instability was more complicated. Steep mid-level lapse rates were in place, but low-level CAPE was close to zero. Forecast soundings had the latter improving; but, I'm such a skeptic of those. Normally early season other rain is falling, and it remains stable. Well no rain was falling south of the boundary. Surface chart in retrospect shows an unstable airmass advecting in unfettered. Sure enough it arrived at the boundary in Middle Tennessee. LLJ strengthened. Alas the 2% TOR area was under the gun. CAMs actually had robust storms, but not necessarily a boundary rider beast. Old fashioned meteorology could have provided a more obvious heads up before the evening news. However, credit some local TV Mets for sounding the alarm on the evening news. Still, it's tough to overcome a 1am long-track cyclical damaging tornado. Dixie Alley is just so awful. It's either busted chases, or much much worse. The human suffering down here is cruel. At least the Vols cheered up Tennessee. https://davieswx.blogspot.com/2020/03/march-3-2020-double-digit-death-toll.html excellent article from Davies.

Even the stubborn Euro gives snow above 4,000 FT. Thickness and 700 mb Ts fall with precip. Thursday is happening at the ski areas. Then we have Friday NWFS.

Flash Drought, but still humid AF and AN temps. Yuck!

Thursday could do it front side above 3,500 FT, but more likely at/above 4,000 FT. NAM is cold surface temps, but has a warm nose at 700 mb, though it's early to drill down that far on the NAM. Euro holds 700 mb below freezing, but surface temps are right only above 4,000 FT. Also got the NWFS section Friday. Overall paint me optimistic for the true mountains and ski areas. Lower elevations cliff dive advisory could be upgraded to warning (552 thickness). Anyway it looks like the ski areas can get another good weekend which is nice for business.

ERTAF has begun! Cue up, It's the Most Wonderful Time of Year! Agree with them though, it looks benign for a while. Just as well until after the Final Four. Japan satellite shows the two Kelvin waves (MJO pulses) well. Also got a trough trying to dig into central China. Probably get a ton of MJO interference though. Though both sets of weekly forecasts appear on fire with the West trough, devil is in the details. Soft underbelly Deep South hints split flow chaos.

MJO problems will keep the weather models as volatile as the stock market this week. Just when we think snow is possible; boom, downside reversal! I still miss Chattanooga's ultimate upside reversal on Feb. 8 sorry I've mentioned it on two threads in five minutes. In all seriousness, I still consider TRI and the Upper Plateau in the game Friday night for wrap around and/or slight NWFS. Maybe I just want to ski one more time.

My guess is some convergence in the wake misses you to the northwest. Have you ever checked up 27? Hypothesis is based on trajectory exactly parallel to the mountains. If from the west or northwest, I figure everybody gets killed by downslope. We know a lot about that in Chattanooga off the Plateau, lol! In other news, Friday evening I'm so glad I missed MRX updating for the Chattanooga area. Never even saw that update. Watched Netflix when it became obvious KCHA temps would hang up as usual. Good for those who got snow OK with the system. Despite the wonderful Feb. 8 surprise, KCHA has adjusted back to just being the cheering section.
