I live in Raleigh and you cannot establish Fescue by planting it this time of the year, even if you plan to water the heck out of it. The hot sun from Mid-Jun through August will just bake it. Do you have lots of shade or is your yard fairly open? If your yard is fairly open I recommend you pass on Fescue and go with a Bermuda type grass. Yes, it will be brown in the winter but once established it will be much easier to keep beautiful in the summer.
Live with the natural grass/weeds until early September. Plan what you want to do and get it established this fall!
