LLJ issues perhaps overdone on the models? If so, watch out.

Edit: SPC says get ready for show time...


DISCUSSION...Recent mesoanalysis shows a strong (i.e. 50-55 kt at
850 mb) low-level jet throughout much of the warm sector
. This
mesoanalysis is verified by area 18Z soundings, with CRP and FWD
sampling 55 kt and 65 kt at 850 mb, respectively. Some convective
contamination may have contributed to the stronger winds at FWD, but
the general expectation is for these strong winds to persist
throughout the warm sector this afternoon and evening.

Given 12z and 18z HRRR tomorrow, I think a convective evolution similar to 4/12/20 may occur where a QLCS producing tornadoes moves through LA/MS through morning and afternoon and renegade supercells form and show the highest tornado threat.

Just comparing purely from a convective evolution standpoint. I think the convective similarities ends with GA/TN and eastward

Now a PDS warning. No large or dangerous wording.

I don't know re the PDS. Maybe because it was heading straight for Jacksboro? The cell looks to be over a sparsely populated area for the next 15-20 minutes. Also appears to be rain-wrapped which is not good.

Yikes, did not expect things to escalate so quickly, especially with the northern storms which were supposed to be in a less favorable environment for significant tornadoes. This outbreak is off to a rough start.
