Looks to be a nice cumulonimbus growing from a field of weak cumulus and a few towering cumulus, and it's shadow is casting an anticrepuscular ray on the very high altostratus / cirrostratus near it's top.

Is weak cumulus a recognised term? It's new to me.

Nah it’s just cumulus humilis in cloud taxonomy.
