What planting zone are you in? If 6 or higher, I would get that seed down ASAP. If 5 or lower, you are probably too late. Enter your zipcode here to find out:

The advantage to fescue is it germinates and establishes faster than KBG. FWIW, underdeveloped cool season grass tolerates cold better than heat and I wouldn't worry about light frosts. I planted tall fescue 11 days ago. We had a few nights here around freezing and I'm seeing healthy sprouts now.
The newer turf-type tall fescues (TTTF) are generally finer bladed than the older KY-31. However different cultivars are bred for different qualities - blade width, color, heat and drought tolerance, etc., and you probably find something that shines in one or two categories or does all of them just OK.
If you are too late now, I personally would not bother with spring planting and wait and do a late summer seeding. Unless the seeding area has some afternoon shade, a spring seeding will have a rough time in the heat of summer unless you are prepared to baby it all summer long.
It says i'm in zone 5b. The reason I wanted to risk is because for the past 3 years, it's been warmer. From one of the articles above, it says Sept 1-30 for southern Illinois. OUCH! I'm in northwest. When I did renovated my lawn 10 years ago, I dropped seeds August 15 and it was a success. It's just that it's too long of a wait for August 2021.
fyi, I bought an active grub killer this morning. I continued raking the dead grass and wow, there's tons of mature grub about an inch long. I had a dead spot last year in front and my neighbor approached me and said
"I know why you have a dead spot there, it was killed by grubs. Grab me a shovel and I'll show you." He cuts the grass and dirt deep and lifted the it. We didn't see anything. LOL! With my findings few days ago, I now know he was only assuming and I think he thinks that grubs live 6-10inches deep. LOL 🤣. Grubs just lives half inch to 1 inch deep, just a little below the roots. He saw me today while I was raking my lawn. He didn't bother to come and ask why I'm pulling out the dead grass. His lawn is also dead.
Do you think I'll be happy with TTTF? It looks very nice on youtube and on pictures.
