The episode as NWS OUN wrote it up.
A strong upper level low moved over the Southern and Central Plains region during the day on Sunday. Adequate moistening and sunshine allowed for modest instability to build within a narrow corridor across central Oklahoma. Isolated thunderstorms developed along a pacific front/dryline feature during the mid afternoon hours. These storms occasionally exhibited supercell characteristics, producing large hail and funnel clouds. One very brief tornado occurred over northeastern Oklahoma county. No damage or injuries occurred.
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 Norman, OK wrote its last area forecast discussion before the first event at Dec 14, 11:43 AM CST, 2 hours 17 minutes earlier.

THUNDERSTORMS ARE ALREADY OCCURRING AHEAD OF THIS FEATURE...AND ARE EXPECTED TO CONTINUE TO EXPAND THROUGH THE DAY AND INTO THE NIGHT TONIGHT. SHORT-RANGE MODELS SUGGEST THAT A BAND OF NUMEROUS SHOWERS AND RELATIVELY WEAK THUNDERSTORMS WILL MOVE EAST ACROSS OKLAHOMA AND NORTH TEXAS WELL AHEAD OF THE DRYLINE.
