SPC added an ENHANCED (risk level 3 of 5) for a swath of Kansas in their update about 30 minutes ago. There are already storms along I-70 in the orange area. The tornado risk has also increased, from a probability standpoint.
Very large hail is also a threat. Hail larger than 1″ is given a 30% probability in the red area. The hatched area has a 10% chance for hail stones larger than 2 inches.
