Big CC drop in Eton, Georgia

storm was just TOR warned a few minutes ago (Murray County)

edit: adjacent Polk County (TN) just TOR warned as well

Really messy and challenging for the NWS offices. Storms seem to overcome some capping inversion in the areas that have not been touched yet. Ramp up and then they go mushy again and linear.

I feel like that’s gonna be the story for rest of the night. Going to be lots of wind damage with spin ups every now and then

TVS south of Cullman, AL.

 

[CamWX]

Warned now.

 

[NWTENN]

That debris signature disappeared about as fast as is possible. My folks were about 15 miles away, directly in the path of that thing. So, so thankful it lifted.

 

[Jimmy Hypocracy]

I mean just looking at the GSP Radar you can tell this is an uncommon setup for us. With the way precip is streaming right out of the S/SW in those little candlewick clusters. This is not going to be a fun night. You guys be safe out there.

The Nam 3k seems much less bullish for the STP across central NC. Although I wouldn't rely on this too much since we are in now-casting, it is, however, encouraging to see.

Warned storm in TN east of Chattanooga, by the NC line. Doesn't look very impressive.

And the tornado signature coming into Jefferson is Gone in 2 scans. These cells just can’t keep going tonight. They flare up, look great, then die. Story of this outbreak

Sometimes, having insane amounts of shear can actually be a hindrance and can be too much to maintain storm rotation.

Hope that will be the case. I'll take anything to lessen the threat a bit here and ease my anxiety.

 

[BirdManDoomW]

The line approaching north west Mississippi and southwestern Tennessee appears to be a growing concern for high wind based on last few scans. Really starting to develop into a “bow echo”.

 

[CamWX]

Warned storm in TN east of Chattanooga, by the NC line. Doesn't look very impressive.

Confirmed tornado in Polk County, TN.

 

[GeorgiaGirl]

Fun! (Latest HRRR, near me, early morning):

 

[BirdManDoomW]

This has my eye Memphis Tennessee southward into much of Mississippi starting to get warned for winds of at least 70mph. It’s actually getting stronger convection wise tonight which isn’t always seen in linear storms this late.

This is good news, and it backed off that supercells in the QLCS look, but it really looked bad for wind damage, almost looks like our classic wintertime QLCSs we get, but just more instability, seems like it did speed up a bit tho, but the tradeoff to a smaller tornado threat was more damaging wind

 

[BirdManDoomW]

Jesus that eastern TN tornado is moving at 65mph. Not a favorable speed to chase for sure I hope law enforcement that reported it didn’t even try.

 

[Psalm 148:8]

The wind gusts here are crazy!!! Hope some of that rain ahead of the storms will stabilize as that line gets to Ga! I do not want to lose power tonite!!!! Or have trees down on my house!

 

[Lostnthaweather85]

Will the air destabilize any between the current line in Alabama and the line in Arkansas?

 

[BufordWX]

Will the air destabilize any between the current line in Alabama and the line in Arkansas?

I believe that 2nd line is supposed to weaken.
