SIGNIFICANT WEATHER ADVISORY FOR SOUTHWESTERN JEFFERSON COUNTY
UNTIL 700 PM CDT...

At 629 PM CDT, Doppler radar was tracking a strong thunderstorm near
North Johns, or near Bessemer, moving north at 45 mph.

Pea size hail and winds in excess of 40 mph will be possible with
this storm.

Locations impacted include...
Southwestern Birmingham, Bessemer, Hueytown, Fairfield, Pleasant
Grove, Midfield, Adamsville, Brighton, Lipscomb, Sylvan Springs,
Mulga, Maytown, North Johns, Birmingham Fairgounds, Edgewater,
Ensley, Legion Field, Forestdale, Splash Adventure and Birmingham
Southern College.

Hey folks...chiming in from Bessemer. That was a pretty stout storm. Be careful out there NW Jefferson County

 

[Equus]

Lots of thunder here from those little cells marching NNW I presume with the warm front.

It’s going to be interesting over the next couple hours for North Alabama. You have those storms racing north on what I’m assuming is the warm front? You also have that rain shield marching east across North Mississippi that would put the brakes on major severe weather. The good news is maybe the threat won’t last all night

Rain shield is moving due N. It's just a question of what the storm mode is and where the warm front is by the time those storm in MS get here. I will say that supercell in MS is on a bad track for Huntsville..

 

[Tennie]

It looks like the Goodman tornado was likely a relative spin-up, as its associated radar signatures was here then gone within a few radar scans.

 

[Richardjacks]

I dont these storms are along the warm front. I believe they are a combination of low level convergence ahead of the low and diffluence aloft mixed with some instablity with little capping...the warm front should be fuether north of here.

 

[Equus]

We're probably going to have a lot of those spinups as the line marches this way. Still have impressive low level shear. Am intrigued to see if anything happens ahead of the line in the warm sector otherwise we're going to have a QLCS-fest plus that echo that's causing the warnings thus far at the apex... and that echo isn't going to pass too far from here.

 

[Richardjacks]

The environment over east Mississippi will start to change in a couple of hours as the upper low tilts and shear begins to strengthen, should lead to more cellular vs linear.

 

[Equus]

Alto damage was pretty high end... have seen pictures floating around with debarking and heavily damaged tossed vehicles in addition to less well built structures destroyed.

Wanna bet the highest concentration of tornado warnings for the day is across eastern MS into AL? Because that's not that far off a possibiliy given the overnight parameters. Gonna stay up laaaate

 

[kcyalater]

I feel like this thing is going to struggle to break up at this point.

 

[MattPetrulli]

Not sure about line breaking up, but can definitely see a QLCS threat going through much of the night.

 

[mattdanielwx]

New tornado watch on the way....likely for parts of Central AL

 

[Bama Ravens]

 

[SilentShadow87]

Two children were killed in a car in Alto. Absolutely horrific.

 

[Bama Ravens]

Interestingly, the STP on the HRRR keeps the highest values down along the coast.

 

[Equus]

Tornado warning NW of Vicksburg on the second line. Lemme say, HRRR did wonderfully. Radar is almost identical to some of the CAM plots from last night, showing multiple lines with isolated rotating semi-discrete stuff embedded.

 

[MattPetrulli]

Tornado issued for cell SW of Louisville, MS. Has a rather strong couplet.

 

[Equus]

Now a small TDS with that

 

[warneagle]

Spotter confirmed tornado near Carthage, MS

 

[DaveFromGA]

 

[WesL]

New TOR warning for Leake and Attala counties in MS.
