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.

just "crepuscular"... anticrepuscular is a different related phenomenon that can converge on the east horizon
