Massive storm clouds seemingly moving together in a thick stream and dipping low over downtown Toronto made for an ominous scene on Tuesday.
CityNews viewers sent in impressive photos of the eerie looking formations, even musing if it was an alien invasion.

Meteorologist Natasha Ramsahai explains the fantastic formations are actually known as shelf clouds.
“They usually occur at the base of a thunderstorm cloud or cumulonimbus cloud,” she says. “They occur along the leading edge of a gust front, so if you see this, it’s about to get very windy for a short period of time.”
Listen to more about the unsettled weather over the next few days from Natasha Ramsahai:
The clouds brought a very brief round of showers to the downtown core and cleared out within minutes.
Pockets of heavy downpours and thunderstorms are expected over the next few days with temperatures in the high 20s or low 30s and humidex values soaring closer to 40.
