A cluster of supercell thunderstorms developed across eastern Nebraska during the afternoon of 16 June 2017 and raced south through the state. The thunderstorms had merged into a large mature complex by early evening, and produced very strong wind gusts (many in excess of 80 mph) along its path. The system persisted after sunset, necessitating a switch from visible satellite imagery to IR. In order to ensure a smooth transition from day to night, a useful strategy is to overlay visible imagery on IR imagery. As the visible pixels fall to 0, the IR pixels will appear in their place. See below for an example from the 16 June 2017 event.
