First post here, was wondering why the other place has been so dead. 
 

Thanks @ClicheVortex2014 for all these great posts again. 
 

HRRR STP pretty strong the next couple hours

Like to say thanks for the new site and I’ll be donating. Couldn’t figure out why the old site was so dead. Everyone stay safe that are ahead of these storms today 

Good to see some familiar names 😁

QLCS tornadoes like to hide on the northern part of bowing segments. I spy at least 3 possible tornadoes.

At this rate, this could be quite the prolific tornado day even without warm sector storms. These tornadoes are weak but spin up quick. They'll likely be disguised as damaging wind reports until offices get out to survey.

Just now, OKwx_2001 said:

That warm sector cell will probably merge with the squall soon so it's potential has likely gone down, which is good 

What's concerning to me is although that supercell never went tornado or even severe warned, it represents a larger trend of warm sector cells getting more and more organized. If this trend continues, it's only a matter of time until they actually produce. And it's only 1:40pm local time.

Warm sector supercells are starting to go tornado warned earlier.

HRRR says parameters should continue to increase in the next hour or so, weaken a bit, then re-strengthen as the sun sets and presumably low-level shear increases

Could be a problem

Yup I was just about to post that. Pretty classic looking supercell. Big compared to many of the supercells we've seen today. Plenty of room to run.

SPC just mentioned this supercell

 

 DISCUSSION...MRMS mosaic radar imagery depicts a broken QLCS from
   the TN/AL border into southeast LA, which continues to progress
   eastward with time. This QLCS has an extensive history of producing
   damaging gusts and tornadoes. Immediately ahead of the squall,
   semi-discrete supercells have recently demonstrated transient
   periods of strong low-level rotation, with up to 40 kt rotational
   velocities noted on some storms (i.e. Wayne County, MS). The 2207Z
   MOB VWP depicts long, curved hodographs, bearing near 400 m2/s2 SRH
   in the 0-1 km layer alone, indicative of ample low-level shear for
   surface-based, sustained supercell structures to produce tornadoes.
   Latest deterministic HRRR and Warn-on-Forecast ensemble guidance
   also depict an appreciable concentration of mid-level rotation
   tracks along the southeast MS/southwest AL border over the next
   couple of hours, and this is where the greatest short-term tornado
   potential resides. The George County, MS supercell may have the best
   tornado potential since it has the longest residence time in the
   warm sector with unimpeded inflow.
