June 20th took us to southern Nebraska. Excessive heat, steep lapse rates, moderate CAPE and moisture, as well as a local boundary across the I-80 corridor would set the stage for severe storms this afternoon and evening. Clusters of storms formed west of Kearney, NE and drifted south. Their outflows kicked up new storms ahead of them by early evening. Due to steep lapse rates and optimum freezing levels, the storms were incredibly electrified! Some of the best lightning of 2017 occurred that evening, well into the night time hours. We stayed in front of the cluster of severe storms into Kansas well into the night time hours. A great day for the lightning lovers! And who isn’t one????
