What happened

The episode as NWS OUN wrote it up.

A boundary moved southeast into Oklahoma during the afternoon hours of the 9th. An upper level wave accompanied this front, and combined with afternoon heating helping severe thunderstorms to develop during the afternoon and overnight hours. Thunderstorms also developed on the many outflow boundaries that were created throughout the event. Hail, high winds and flash flooding were reported.

LOW-LEVEL JET WEAKENS SUFFICIENTLY. ADDITIONAL SCATTERED DEVELOPMENT
POSSIBLE THIS AFTERNOON ON OUTFLOW BOUNDARIES OVER THE NORTHWEST
HALF OF CWA. MUCH MORE WIDESPREAD ACTIVITY EXPECTED TO DEVELOP
OVER OR NEAR NORTHWEST OKLAHOMA REGION THIS EVENING AND SHIFT
EAST AND SOUTHEAST TONIGHT INTO TUESDAY MORNING. THIS WILL LIKELY
BE A REPEAT SCENARIO THE NEXT FEW DAYS...WITH THE FOCUS SHIFTING
FARTHER SOUTH EACH DAY AS FRONTAL BOUNDARY ENTERS REGION WEDNESDAY
AND BECOMES STATIONARY. GIVEN ANTECEDENT CONDITIONS MOST AREAS...HEAVY
RAIN WORDING WILL BE ADDED TO FORECASTS WHERE WE HAVE HIGHER
CONFIDENCE OF EXCESSIVE RAIN.

BOTH NAM AND GFS MASS FIELDS HEAVILY IMPACTED BY CONVECTIVE FEEDBACK
PROBLEMS...WITH THE GFS BEING AFFECTED THE MOST. THEREFORE...LITTLE
