Environment

A trough was moving into the Ohio valley. Along with the trough, a surface cold front was moving into the region from the west. Central Kentucky and Southern Indiana were well within the warm sector of this system.

Figure 1: 500mb Chart 18Z	Figure 2: 850mb Chart 18Z	Figure 3: Surface Chart 18Z

Scattered skies allowed for ample surface warming and increased surface based instability to develop in the early afternoon. Effective shear was 40-50kts within the region, plenty for organized storms to develop. 

Figure 4: SBCAPE / CIN 18Z	Figure 5: Effective Shear 18Z	Figure 6: 0-1km SRH 18Z

The Supercell Composite Parameter should a good signal for organized supercells to develop. Low LCLs around 600-750 meters was a good indicator that tornadoes would be possible.
