Mesoscale Discussion 1986

   Areas affected...northeastern Louisiana to western/central Alabama

 

   Concerning...Tornado Watch 573...574...575...

 

   Valid 300215Z - 300315Z

 

   CORRECTED FOR DISCUSSION TEXT

 

   The severe weather threat for Tornado Watch 573, 574, 575 continues.

 

   SUMMARY...Severe/tornado risk continues across portions of WW

   573/574/575.

 

   DISCUSSION...Widespread thunderstorms continue across the Mid South

   and central Gulf Coast states. The bulk of the ongoing

   severe/tornado risk persists mainly across the central third or so

   of Mississippi into west-central Alabama.  

 

   Across this region, a moist *airmass* persists, ahead of the

   advancing cold front that is now crossing Arkansas/East Texas. 

   Meanwhile, low-level shear has increased a bit over the past hour or

   so, as flow in the 1 to 2km layer gradually strengthens.

 

   While storms have decreased a bit with respect to organization in

   general over the past hour -- likely due to modest after-dark

   stabilization, some increase is noted within streamers of showery

   convective cells south of the main convection -- i.e. across

   southeastern Louisiana and southern Mississippi -- including hints

   of weak rotation. This may be reflective of the aforementioned

   increase in low-level shear, which overall suggests that the

   potential for tornadoes continues across the area.

That cell east of the radar and down by the MS/LA border need to be watched

This evening presents something we didn't have during the day; an effective warm front for storms to ride and possibly locally backed surface winds

The cell east of Jackson radar now has a huge BWER

I think these supercells are struggling to produce because of weak low-level instability. Hope it stays that way

The entire region's LLLR's are less than 6.0/c so i'd say that's probably what's happening, could still be a couple surprises who knows but I agree that the main tornado threat may be behind us

Mid-level mesos are having no problem, and low-level shear is certainly not an issue so it has to come down to the low-level thermos. Doubt there’s an inversion but yeah, I’d bet LLLR is it

Ive been watching this in AL that just went tornado-warned it has arguably the best shear and most potential SRH thanks to a big looping hodograph out of the whole event

EDIT: Confirmed now

Yikes, picked up a bit on CC right as it went over highway.
