The episode as NWS TSA wrote it up.
A slow moving upper level storm system approaching the Southern Plains from the Southern Rockies resulted in a persistent moist and unstable air mass over eastern Oklahoma during late May. On the 26th, two areas of thunderstorms developed and moved across the area. These storms were very efficient rain producers and some moved repeatedly over the same areas, resulting in locally heavy rainfall and some flash flooding.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tulsa, OK wrote its last area forecast discussion before the first event at May 26, 1:54 PM CST, 1 hour 34 minutes earlier.
