Sun looks like a tough day to chase with guidance showing convection lining out quickly after initiation, and embedded supercells being the main mode in hard to chase territory. 12z NAM has the right exit region of the jet offering support over EC Oklahoma around 21z with mid 60s DPs, 200 0-1 Helicity, and 2000+ CAPE. Stronger instability and weaker shear are present further south into TX,AR, and LA where a QLCS appears to push through into the middle of the night. The strongest helicity tracks are currently shown crossing into WC Missouri during daylight which is where I'd focus on positions if I could be out there. Should be interesting to see how this plays out in future model runs.
