FWIW, marginal storm risk for the day:

...Arklatex to parts of Ohio/Tennessee Valleys...
A near-frontal band of convection, with widely scattered embedded
thunderstorms, is apparent on the western rim of the outlook area.
This activity will continue to shift eastward through the day in an
environment of favorable deep/speed shear but marginal instability,
offering the threat for isolated severe wind gusts and marginal
hail. A tornado cannot be ruled out.

Looks a little suspect.

Well... seems we don't need to exactly sleep on today's risk.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS EVENING
ACROSS PARTS OF NORTHEASTERN MISSISSIPPI AND NORTHWESTERN ALABAMA
INTO MIDDLE TENNESSEE...
...SUMMARY...
A few severe thunderstorms are possible this evening within a
corridor across northeastern Mississippi and northwestern Alabama
into middle Tennessee. This includes a risk for potentially
damaging wind gusts and perhaps a couple of tornadoes.
...20Z Outlook Update...
Adjustments to the categorical and probabilistic outlook lines were
made to account for the progression of synoptic and sub-synoptic
features, and latest trends concerning ongoing destabilization.
...Mid South vicinity...
Low-level moisture return is ongoing on southerly return flow across
the lower Mississippi into Tennessee Valleys. This appears to be
contributing to modest boundary-layer destabilization (including
CAPE up to 500-1000 J/kg), which is expected to continue developing
northeastward as an initial short wave impulse, which has emerged
from the Southwest, progresses east-northeast of the central Great
Plains late this afternoon and evening. As the associated frontal
wave migrates into the lower Ohio Valley, there appears a window of
opportunity for vigorous convective development focused along/just
ahead of the trailing surface trough across Tennessee into
Mississippi. This may coincide with a 40-50 kt southerly 850 mb jet
axis, along which enlarged low-level hodographs may become support
of supercells structures accompanied by the risk for damaging wind
gusts and/or a couple of tornadoes. With the influence of the
mid/upper forcing on the warm sector expected to be
glancing/short-lived, it appears this risk will be maximized this
evening, but at least some severe weather potential may linger as
remnant convection spreads eastward/southeastward overnight.

A couple of those cells around Memphis look a bit supercellular.
I see maybe some circulation on velocities, but not very tight. I'm assuming this is all fairly elevated.
-
Maybe a supercell will hit Bruce, I wouldn't want him to have to storm chase.

thanks bud bring it . Hopefully we can all endure some action this spring severe wise...
-
If I never see another severe weather event it'll be too soon, a tornado killed my mother in 1974 so I never wish for severe storms for anyone.

Bruce, how clueless are you when you post? Tennessee had 27 tornado fatalities last year. I'm sure hardly anyone wants severe weather.
It's a fact of life, and it's inescapable, but come on, man. I have to think you are just trolling when you post things like that.
-
Severe risk will be nil in eastern areas. Forecast high was 62, but the actual afternoon high was 47. There may be some elevated instability, but storms will quickly weaken as they head east into our much cooler environment.

I agree there won't be much of a severe threat in East TN but the temps actually seem to be doing what they were forecast to do. I was surprised at temps staying in the 40s this afternoon but when I looked at the hourly forecast we're supposed to warm as the front comes through with our high in the 60s happening at 11:59pm. Who knows if that will verify or not, but it's what's supposed to happen.

I guess it could happen if winds pick up as predicted, and it mixes the warmer air down. Right now, nary a breeze here.
Southern valley and Plateau does have a very low end risk of a strong/severe storm.
3. Low-end risk for a strong/marginally severe storm or two in the
Plateau/southern Tennessee Valley areas during the 10 p.m. - 3 a.m.
timeframe. An isolated, brief tornado and damaging winds are the
main concerns.

It mentions scattered storms. One storm heading into Henderson, TN is showing some rotation.

I sure can relate and so sorry about your mother! I lost several classmates in North Alabama in in April 1974. Our family was lucky as a Super cell was headed right at us and veered away at the last minute. I have been through many tornadoes in my life but always got lucky. I get extremely anxious when severe weather is close by. I never would wish for severe weather at all. Give me sunshine or snow. Not Carnage and devastation! :(
-
I'd be happy with just some good thunder and lightning. It's been far too boring for several months.
-
Sever Thunderstorm Warning issued for me!
Storm is going to go right over schneitzeit, then I'll be next.
-
And heading right towards me.
-
Good bit of lightning, thunder and heavy rain passed through.

I was a 13 year old kid in that 74 Black Wednesday...completely tore up our house and killed my aunt and uncle...We lived in Franklin Co right by Tim's Ford Dam

Intense storm in Nolensville.

The storm near Lobelville moving into Hickman County is starting to rotate.

I am seeing lightning and hearing thunder out here in Lascassas for the first time since late August.

I need to keep an eye on that. The hook would sweep right over my house.

It is going to come right over my house too! Already had one round of thunder and lightening and very heavy rain. Just want to keep my power on.

Just walked out to get the mail that ran late tonight and it's warming up with a heavy fog building. Very strange tonight.

Pretty intense cell passing through.
I wish the NWS hadn't changed their radar product. With no county lines, I can't tell where the storms are relative to my home. I'm using Accuweather's radar for reference tonight. I think NWS's update is a disservice to the public.

Wow. Actually dropped a Tornado Watch. Definitely did not see that coming.

Great work from MTEMC. Lights back on.

I'd think about splurging for Radarscope. Available for both Android and iOS. 9.95 one time purchase. It's much better than any web-based platform.

The cell over Polk county is marked 1.25

I've really enjoyed Radarscope. Worth the buy...and a good start for amateur chasers.

This is what I use for the time being. Similar to the old NWS product.

that is exactly what i use. love it

Sounds like Trussville got hit last night. Seems like that area just north of Birmingham is a hot spot for tornadoes.

One dead, 30 injured in Fultondale, Alabama. Tornado width was 1/4 mile wide.
The death was a young adult who was crushed beneath the rubble in his home.

Yet again another southern nocturnal strong to violent tornado in a populated area when it was NOT expected to be able to get one that strong, very similar to our march storm last year.

Couldn't have said that better myself.
Nocturnal? Check.
Wintertime? Check.
Unexpected? Check.
Significant tornado (EF3 or higher)? Check.
Deadly? Sadly, check.
All the boxes are checked for a rogue storm. @justinmundie, are you there? How aware of this pending disaster were the folks in Birmingham?

Even spann seemed a bit caught off guard when he saw the debris signature i watched his coverage ( he is just the best at that ) the only real difference was the fact it was not as long track....but my gosh this is twice in 10 months that a Major tornado happened when it really never showed signs of being capable, kind of scary to think how little we really know , i am sure people went to bed thinking it was just another garden variety storm line like we always get
