That church I mentioned before? Wiped clean, although probably not built super sturdily.

Impressive damage from the Salado tornado. Clearly a very strong tornado.

Impressive QLCS currently moving through NW Louisiana. Several intense spin-ups associated with it in and north of the Shreveport area.

 

[OHWX97]

Haughton, LA is likely about to take a direct hit from a damaging tornado.

CC has gotten noisy approaching Haughton but that is a QLCS velocity signature you ALWAYS take very seriously

I didn't see a CC drop as it moved through town, but I'm sure they experienced some intense straight line winds at the very least.

Small supercell out ahead of the line near Hope, AR is now tornado warned

 

[MattPetrulli]

Well the 00z HRRR is certainly concerning across the Mid South tomorrow. Depiction is mixed mode (but with a number of supercells), but the parameter space across much of the region supports significant tornadoes with very impressive mid level lapse rates, plenty of moisture, and strong low level shear. We'll have to see how tonights convection from Texas behaves since it seems there's a pretty mature MCS ongoing right now with a cold pool, but the timing of the mid-level shortwave trough rounding the base of the parent upper low is pretty ideal.

Important trend from 00z HRRR to 02z HRRR has been more and earlier convection
00z

02z

Though, 02z only runs through 20z, crapvection could be a limiting factor if this pans out and should be noted if the trend continues in either direction. Imo think the moderate for tornadoes should be expanded a little to the north and east to include more of North Central MS, East AR, and West TN.

 

[OHWX97]

Near Castor, LA... wow!

 

[Equus]

Big time outflow surge like that usually precedes the more significant of the QLCS tornadoes; bad news coming up looks like

There was a damaging tornado on the ground with a TDS on this storm when it was south of Shreveport.

 

[Taylor Campbell]

Wow. Where was Doppler on Wheels and the research group for this behemoth?

 

[OHWX97]

Wow. Where was Doppler on Wheels and the research group for this behemoth?

Aren't most of them still stationed in the southeast for the PERiL project?

 

[OHWX97]

Really bad situation ongoing in and around Riceville, IA. Multiple damaging tornadoes have occurred near the city.

 

[OHWX97]

Spring Valley, MN... good grief.

 

[Equus]

Yeah that line is going nuts in that super high shear environment right now

 

[Shakespeare 2016]

Really bad situation ongoing in and around Riceville, IA. Multiple damaging tornadoes have occurred near the city.

Do you have a source?

 

[OHWX97]

Do you have a source?

Look at what @Equus posted above you.
