Today on spaceweather.com (if not today look in archives -see bottom) for these images. It says that mammatus are "when storms are breaking up"

Yesterday in the Czech Republic, Matus Kocka photographed some "very strange clouds" hanging over Brno where he is going to college:
These are mammatus clouds. They form in turbulent air on the undersides of thunderstorms.

Indeed, Kocka photographed these "after some strong weather" swept through Brno. More images: #1, #2, #3, #4
