The State Climate Office of North Carolina posted a description of the locally heavy rains that occurred in central NC this past Saturday on their blog at https://climate.ncsu.edu/climateblog?id=197&h=5666e5c1.  One CoCoRaHS observer in Cary NC reported 7.52 inches for the day.  Estimates of the return period are that some areas received a 100-year event or more.  If you don’t know what a return period is or just want to know more, the article has a good description of what it is and where you can get estimates of return period for your area.
