Hank's posted nudged me to go have a look at the archived analysis data (go to ready.arl.noaa.gov and selected "Archived Meteorology" on the left).  

With the relatively light winds out of the west, I would guess the launch site was along I-40 east of or near Asheville.

This appears to have been a flight launched late morning on July 5, 2017 according to the timestamps visible in the Facebook photos.  I think it was a GoPro camera, photo filenames begin with "G".  T-shirt on the guy that launched it is for a shop in Charlottesville VA.  Payload was found about a week ago near Statesville NC.
