Some (myself included) are finding the dense clustery convection (even with strong UH streaks) apparent on the HRRR and 3KM NAM concerning for chaseable tornado potential. I'll re-post what I just posted on ST Discord:
I admit I often fail to do this enough, so let's go through some of the factors that usually lead to the convective mess/quick upscale growth the CAMs are hinting at.
Low-mid level VBV? Not really seeing it.
Shear vectors parallel to the initiating boundary? Not that I'm seeing.
Too much forcing for too little capping? Possibly.
Any others I'm missing?
Although regarding the forcing, isn't that usually a problem with a very strong synoptic system? Per mesoanalysis, this SFC low should be deepening with time (a positive if you want storms), but not getting TOO deep (~1000MB), which might actually lead to a higher significant tornado threat.
