On August 4th, a strong thunderstorm passed over Marblehead and I ended up chasing the lightning around town trying to catch bolts from various locations.  This image was taken from the beginning of the storm as the grey clouds formed and overtook the sky over Marblehead.  I wasn’t sure how to describe these impressive cloud formations but they seemed to form a churning sky over Marblehead Light so I stuck with that terminology.  If someone has a better description, please let me know.

Here are more images from this outing on August 4th:
