Cloud build-up

Lots of cloud activity today, with cumulus congestus building up in the sunshine.

For a while, there was a mixture of cirrus, contrails, and a few puffs of cumulus mediocris.

Then a build-up of cumulus clouds, like this cloud mountain.

It looked like they were already having rain to the south east.

Forms were changing fast.

The mountain peak was overtaken by a cumulonimbus capillatus (with the fringe on the top).
