I live in the Northwest but
I am a Landscape Contractor. Time him that fine fescue will have thatch problems which can make for bug problems down the road. If at all possible preannual rye grass is better. Not annual rye grass. 100% preannual. I have some that looks green all summer long with no water.
I am not from your side of the country. But If you can go with preannual rye. I would. Lots easier to maintain.
