My dad had a successful chase today out in eastern Kansas, south of the Garden City area. He saw multiple tornado/landspouts today as I nowcasted him around the storm and provided updates. I took a bunch of PNG files from GR but I cant seem to get them to show up. The storm my dad got on took a classic right turn into the surface flow and had an amazing hook. Above I put multiple maps showing real time data as the tornadoes were dropping. I outlined the area where the tornadoes developed and from diagnosing today I figured it was the area of high Helicity values, the storm motions and high Cape values(3000J) that helped this storm produce when it did.
