There was one word that came to mind when I looked at this setup: YUCK!
The 15Z stuff looks a little more promising, so I guess since this is a virtual chase I'll sit in Dimmit, TX for this one. This kind of setup simply would not be good looking enough to drag me out on a real chase, though.
EDIT: (forecast reasoning): Weak and unorganized, but moist, sfc flow under weak low-mid level flow, which is all under a departing shortwave ridge, but downstream of a decent looking 300 mb shortwave trough. I see the 500 mb shortwave, but it's not the most impressive thing I've ever seen. Seems like the lift associated with it will be greater at higher altitudes, thus effectively pulling up any cap that there may be. Soundings looked either too high-based farther west or moist adiabatic farther east, lending to less instability. Nonetheless, early morning convection likely moistening the boundary layer, thus allowing for parcels to saturate at very low levels and become unstable anyway. Convection in SW OK also putting out an outflow boundary. Thus, this setup looks like a mesoscale setup, and it's hard to analyze a mesoscale scenario with the synoptic charts that have been provided. I will be a frequent visitor to the Oklahoma and West Texas mesonet sites today, waiting for the day's events to fire along an outflow boundary, perhaps the one flowing southwestward from the convection in SW OK.
I guess I'll see if my reasoning verifies, though. I could be dead wrong. I just kind of laughed at this setup when I first looked at it.
