Storms developing south of JAN have access to richer moisture/instability and steeper mid level lapse rates. The one near Brookhaven is really going up fast.

Yep.

 

Still early, but the combination of low CAPE, not so great mid-level lapse rates and a LL flow coming from the worked over MCS environment is clearly hindering things thus far along/north of I-20 in MS. The environment across much of AL isn't any better. Given how quickly convection and the front are pushing east towards an even more unfavorable environment, the overall threat (tor wise) across a large portion of the risk area should be in question.

It's a good thing that today's threat for strong tornadoes is lower, as the same areas that were hit yesterday are getting hit again.

 

Quick aside: What's the link to ECMWF's new model page?

Nothing really exploding in MS or AL.

 

Yeah there are some nice discrete cells, but they are northwest  of the best LLJ.  The crapvection in southern Alabama is also preventing stuff to the northwest from really getting going. Yesterday made it memorable enough though.

There is a pretty tiny corridor of enhanced tornado potential right now in far southern MS. Further west the continued production of convection over southern AL and FL has left the area with lower lapse rates and pretty negligible low level shear. The effective inflow layer shear in Birmingham as of 18 UTC was 5 knots...

The HRRR is also not very bullish about the threat further east with the low-level backing inflow actually eating away SB CAPE with time. I think its becoming increasingly likely the tornado threat won't be realized further east.

The environment is all kinds of messed up. As others have said, there does appear to be a small region of potential across SE MS into portions of SW AL and the FL panhandle, but even there time is kind of ticking. Dews in the upper 50s in some stations across N AL doesn't bode well for the Tornado Watch.
