The severe thunderstorms which swept across Victoria caused flash flooding and leaving tens of thousands without power.
They hit Melbourne's CBD around dinner time, just as people were preparing for a night in front of the television (or their smartphones and tablets).
Pulled from their screens, residents turned their gaze to the dazzling electrical show in the sky.
When the storm passed, they noticed oddly shaped clouds and took to social media to share their finds.
Bureau of Meteorology forecaster Dean Marramore said the circular clouds were called mammatus clouds.
"It's a Latin name and it means breast, udder or mammary gland," he said.
"Basically, that's what they look like."
Mammatus clouds get their shape when cold air sinks below the cloud.
"They normally form on the back of severe thunderstorms like the one we had last night," Mr Marramore said.
"You get a lot of air rise up into the storm and then some of it tries to sink back down."
Mr Marramore said the uncommon cloud formation generally lasted between 15 and 20 minutes.
He said Tuesday's mammatus clouds were particularly "impressive" because they occurred as the sun was setting.
