The lower of those two independent cells just north of Elkhart TX just showed a velocity couplet on the last scan.

I'm at 65/57 right ahead of that leading line that passed GWX, assuming still in the cold pool from the earlier hailers since that outflow boundary was pretty easy to track all the way into MS. It's weakening so fingers crossed nothing gets too out of control here with the surface relatively stable. Will prolly still stay up and watch it anyway.

I feel like in a lot of severe events where a predominantly linear mode is expected, the forecast often mentions the possibility of stronger tornadoes from discrete supercells ahead of the line, but it rarely pans out. This is one of the few times I've seen it in this classic a fashion.

It's also very odd how the echo is oriented NW-SE (like an upper Midwest summertime, southeastward-moving northwest flow storm) yet the storm is still moving in the traditional NE direction.

Also interesting that despite a 10% hatched tornado probability zone on the convective outlook, there's not a single red box in effect (all blue). I've seen them routinely issue tornado watches in 5% contours.

NWS Birmingham has my location in a marginal risk in the morning; whereas, SPC says enhanced. Pretty big discrepancy!
In contrast, BMX has a much larger area of the CWA in the Moderate Risk category than the SPC. Hopefully BMX knows best here, at least with keeping the bad stuff south this time!

So this fairly discrete supercell near Washington, LA decided to pop up a velocity couplet and prompt a TOR warning out of NOWHERE

Looks like the tornado has finally lifted, let's hope this thing doesn't decide to drop another tornado

BMX has removed areas north of Birmingham from the risk.

Tornado Watch out for southern Alabama and the Florida Panhandle. A stormy morning at the beaches. North of the line, a big blob of heavy rain between the coast and Birmingham.
