These are Mummatus clouds, a fairly new cloud classification that’s only been recognized for the last few years. Their name derives from the Latin word “mamma”, meaning udder or breast (for fairly obvious reasons!). Their formation is still fairly mysterious, with more than ten proposed mechanisms. They’re often associated with severe thunderstorms.
