I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Your lawn could be turning brown from a couple of different things. It may be drought or it could be a disease. I suggest you take a sample of lawn about 4X4" with some soil and roots. Take the sample from the zone between healthy and dead grass. Then put it in a ziplock bag and take it to your County Extension Office and see if they can identify the problem and if necessary prescribe an appropriate remedy. Taking some photos may also be helpful to them in their diagnosis.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
