What forms of ID do I need to fly domestically from Massachusetts after October, 2018?

I am planning to fly to Texas in a few weeks, but I do not have a Read ID. I have a standard Massachusetts license and a passport, and the passport is going to expire within 6 months.

To fly domestically would I need to renew my passport (even though it is technically still valid)? Do I even need my passport at this time — would my standard license still work?
