For me, some of the CAM's have been hinting at pre-frontal supercell activity on the morning of 4/24, but the thermodynamics are too marginal to support several, maybe a few supercells could form due to kinematic intensity. Any supercell that does form will have significant tornado potential, but the potential for this scenario to occur is over such a large area that it's hard to tell. Most of the talk is about the dryline and shear potential in TX/OK/LA, but MS, AL, and FL should be watched too.
