These crazy-looking clouds recently covered the sky in Saskatchewan. What are they?

These clouds are called mammatus clouds.The rounded and smooth look of mammutus clouds often captivate onlookers. They are often found underneath anvil clouds of severe thunderstorms. Anvil clouds are the flat top of a thunderstorm, or cumulonimbus cloud. It takes a turbulent atmosphere for these clouds to develop. However, mammutus clouds can also form underneath clouds associated with non-severe thunderstorms.

CBC (Canadian Broadcasting Corporation) News compiled photos of a recent event where mammutus clouds covered the sky in Saskatchewan.

Centre County, PA (1792)
Quote from the diary of William Colbert, a Methodist Circuit Rider up in Centre County: "A very cold morning. It was surprising to see so much snow on the ground at this season of the year. The limbs of the peach trees broke, and large limbs of the oaks broke down, and saplings bent across the road. It began to snow last night before we went to bed. I came out of my way by Lamb's to Phillip Antes."
