Mega Audino forgotten?

I tried to do Mega Audino raid day, but was stuck in a Kroger during a Tornado warning. Ended up with one remote raid, but only have 175/200 mega energy to evolve it.

I was so sad that it wasn’t brought back for Kalos Fest when it seemed like every other Mega was involved. Any ideas on when it’s coming back or how to get the last 25 energy needed?
