A thunderstorm that formed near the Sydney CBD late Thursday, December 8, 2016 created a spectacular lightshow, with thousands of bolts striking in many directions. After a hot and clear day of 31 °C (87.8 °F) temperatures, the skies suddenly turned black as thunder and lightning raged overhead. Loud booms were heard as lightning crashed down in the CBD and surrounding areas, leading people to run for cover, media reported. The storm continued for over 2 hours throwing out cloud to cloud and cloud to ground lightning bolts, FreeNewsAU, an independent news and severe weather media based in Sydney, reported. A number of Anvil Crawlers, horizontal, tree-like, in-cloud lightning discharges whose leader propagation is resolvable to the human eye, were also noted.
