Last Saturday a thunderstorm occurred north of Houston, TX. A one-minute video captured from the storm is embedded below. The audio has been processed to only 25% of the sound pressure levels recorded. Nothing much is lost since there is mainly only the sound of wind and ambient traffic noise. What was different about this type of storm was the frequency of lightning and the appearance that the ribbons of lightning seems to jump from cloud to cloud, rarely connecting with the ground. The video shows the frequency of lightning in real time. There was no audible thunder to accompany the bolts. This is the type of of lightning that we used to call heat lightning.
