Compact yet intense low pressure area is currently in place over western Kansas. Wind analysis indicates intense wind spinning in that area, leading to likely spinning in the atmosphere. 700mb and 300mb maps also indicate the presence of a storm system in the area.
Current radar is indicating a strong storm cluster in north central Kansas, as well as a couple 'popcorn' cells along the western edge of the tornado watch box. These will likely be the supercells that will have to be watched.
Modest instability is in place. With the close proximity of the frontal boundary to the watch box, a tight temperature gradient combined with a fairly intense wind field are making for fair tornado conditions.
