The episode as NWS OUN wrote it up.
A weak cold front became stationary and began slowly lifting as a warm front by late afternoon. North of the front, isolated thunderstorms developed in an environment characterized by very weak shear and dry low levels. This caused pulse storms which produced spotty damaging winds once they collapsed.

NWS Norman, OK wrote its last area forecast discussion before the first event at Sep 16, 2:38 PM CST, 2 hours 17 minutes earlier.
