Brief showers or (as yesterday afternoon) thunderstorms with loud, crashing thunder and semi-torrential rain.
One day I photographed some clouds in the sky before the rain arrived.
And on another day, SWMBO spotted and photographed this rather strange cloud which looked like one side had been sheared off.
Note: the last picture was taken through the windshield of a moving car which accounts for the extraneous light poles and road sign.
Clouds are always fascinating.
