A tornado warning has been issued--after the cell passed over the town. Fortunately, it doesn't look like it touched down on the town. However, it appears that Jordan Hall might have an incipient tornado on his stream:

Cell near meridian Ms will need to be watched

It means the radar stops the volume scan halfway through, rescans the lowest four levels, and then finishes the rest of the volume scan.

is that a better scan??

It gives data in the lower levels more frequently (approximately twice as fast, depending on the exact coverage pattern).

Seems like these renegade storms are having trouble keeping their spin. Its only 59 in Selma, so im not sure how these storms are gonna grow once they get over to this area
I wonder whether the warm sector might actually be more stable (especially in the lower levels) than the forecasts anticipated...
Columbia Report: Lakeview subdivision has damage and trees down. A couple of homes in the area as well as businesses, received damage., Per EM

Areas affected...southeast MS and southwest AL
Concerning...Tornado Watch 5...6...
Valid 122311Z - 130045Z
The severe weather threat for Tornado Watch 5, 6 continues.
SUMMARY...Primary tornado threat will persist near the warm front,
especially with discrete/semi-discrete supercells that cross/remain
anchored along it. A strong tornado is possible.
DISCUSSION...Several supercells have occurred over the past hour,
mainly from parts of south-central MS into southwest AL. The
environment will remain quite conductive to low-level rotation,
especially near/along the wavy west/east-oriented warm front that
extends roughly from Simpson County, MS to Montgomery County, AL.
Discrete and semi-discrete supercells that can continue to
regenerate across eastern LA into southeast MS will be the most
likely candidates for eventually sustaining a longer-lived tornado
as they impinge on the vorticity-enriched warm front. Overall setup,
with peak STP having increased to a 3 as of 22Z, should favor
potential for a strong tornado.
The northern extent of the tornado threat will be limited by cooler
temperatures. Per early afternoon observed and RAP forecast
soundings, as storms move north of the 65-66 F isodrosotherm, the
tornado threat will diminish. Surface winds deeper into the warm
sector across LA are slightly veered and modulating to some extent
low-level hodograph curvature.

Watching the storm near state line. Getting stronger

I see two possible issues that have kept us from having sustained mesocyclones:
1.) There is some veer-back-veer in the 3km ish range that is interrupting the organization of a persistent mesocyclone.
2.) The low level lapse rates are a little paltry. Stronger low-level lapse rates would improve the stretching of the updraft near the surface.
I still think we will see an uptick in tornado activity as the LLJ strengthens during the evening, especially in storms that root themselves along the warm front or an outflow boundary that was left behind this morning.
