What happened
The episode as NWS OUN wrote it up.
A large upper trough became cut off from the flow across the Southern High Plains. This brought favorable wind shear over much of southern and western Oklahoma, but due to widespread cloud cover, instability was marginal. Still, at least one severe thunderstorm occurred during the late afternoon with optimal heating.

Area forecast discussion, May 26, 7:04 PM CST, 1 hour 31 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NORMAN OK 804 PM CDT MON MAY 26 2014 .UPDATE... ADJUSTED RAIN CHANCES THIS EVENING. && .DISCUSSION... A FEW SEVERE STORMS ARE POSSIBLE IN WESTERN NORTH TEXAS THIS EVENING. LATEST RADAR INDICATED STRONG STORMS IN FOARD AND KNOX COUNTIES IN TEXAS. THESE STORMS HAVE BEEN STRONGER DUE TO HIGHER BULK SHEAR OF 30-35KT. THESE STORMS WILL CONTINUE TO MOVE EAST OVER THE NEXT FEW HOURS. DOUBT STORMS WILL INTENSIFY. THE LOSS OF DAYTIME HEATING AND STORMS MOVING INTO OUTFLOW BOUNDARIES FROM PREVIOUS CONVECTION WOULD SUGGEST RAPID WEAKENING IN THE NEXT 1 TO 2 HOURS...THOUGH AN INCREASING LOW LEVEL JET MAY SUSTAIN THEM. REGARDLESS... CANNOT RULE OUT A STRAY HALF DOLLAR HAIL OR 60 MPH WIND REPORT THIS EVENING ACROSS WESTERN NORTH TEXAS. OTHER NONSEVERE STORMS CONTINUE ACROSS CENTRAL AND SOUTHWESTERN OKLAHOMA WHERE SHEAR IS WEAKER. THESE STORMS ARE EXPECTED TO DIMINISH IN THE NEXT FEW HOURS DUE TO THE LOSS OF DAYTIME HEATING. BRIEF GUSTY WINDS AND LOCALLY HEAVY RAINFALL ARE POSSIBLE WITH THESE STORMS. HEAVY RAINFALL REMAINS A CONCERN TONIGHT...ESPECIALLY WITH THE STORMS IN WESTERN NORTH TEXAS AND SOUTHERN OKLAHOMA DUE TO THE INCREASING LOW LEVEL JET. SINCE MANY OF THESE AREAS HAVE NOT RECEIVED MUCH RAINFALL IN THE LAST FEW DAYS...DO NOT PLAN TO ISSUE ANY FLASH FLOOD WATCHES. TIERED RAIN CHANCES FROM 20 TO 30 PERCENT IN NORTHWEST OKLAHOMA WHERE LITTLE TO NO RAIN IS EXPECTED TO 80 TO 90 PERCENT IN WESTERN NORTH TEXAS. THE APPROACH OF THE MID/UPPER LOW WILL ALLOW FOR RAIN CHANCES TO CONTINUE THROUGHOUT THE ENTIRE NIGHT TONIGHT. PRODUCTS HAVE BEEN UPDATED. MBS && .PREV DISCUSSION... /ISSUED 627 PM CDT MON MAY 26 2014/ DISCUSSION... AVIATION DISCUSSION FOR THE 00Z TAFS IS BELOW. AVIATION... HAVE LOW CONFIDENCE IN THE TAFS. THE FORECAST REMAINS COMPLICATED. SHRA/TSRA WILL CONTINUE TO AFFECT MOST SITES BRINGING BRIEF MVFR/IFR CONDITIONS ALONG WITH GUSTY VARIABLE WINDS. GENERALLY FORECAST WORSENING CONDITIONS WITH ALL SITES EXCEPT KWWR AND KGAG BECOMING MVFR 12Z. CONDITIONS WILL IMPROVE WEST TO EAST AFTER 12Z. MBS PREV DISCUSSION... /ISSUED 359 PM CDT MON MAY 26 2014/ DISCUSSION... ANOTHER COMPLEX FORECAST FOR TONIGHT...AS THE UPPER LOW SLIDES OVERHEAD. STORMS ARE ONCE AGAIN ONGOING ACROSS NE OK THIS AFTERNOON...AND PERSISTENT LIFT ACROSS LUB FA HAS KEPT MOIST CONVECTION PRESENT THERE THROUGHOUT MOST OF THE DAY. EARLY MORNING CONVECTION ACROSS SW OK/WESTERN N TX STABILIZED OUR AREA SO THERE HAS BEEN VERY LITTLE REDEVELOPMENT OUT THERE. HOWEVER...BELIEVE MOIST CONVECTION WILL DEVELOP LATER THIS EVENING AS UPPER LOW IMPACTS THE REGION. THE MAIN QUESTION IS...WHERE EXACTLY? GIVEN CURRENT TRENDS AND BEST PLACEMENT FOR UPPER DIV AND DIFFLUENCE...FEEL A FEW AREAS MAY BE FAVORED. INITIALLY SW...W AND W CENTRAL OK...AND PERHAPS PORTIONS OF WESTERN NORTH TEXAS BEFORE MIDNIGHT...AND THEN SOUTHERN/SE OK CLOSER TO SUNRISE AS THE UPPER LOW MEANDERS SE A BIT. MODEL QPF PLACEMENT HAS BEEN FAIRLY INCONSISTENT WITH THIS SYSTEM TO SAY THE LEAST SO DID NOT GO ABOVE AN INCH ANYWHERE FOR NOW GIVEN LACK OF CONFIDENCE. HOWEVER...CONSIDERING THE POSITION OF THE LOW BY TOMORROW MORNING AND DEPTH OF MOISTURE ACROSS THE SE/E FA DID INCREASE POPS TO NEAR 70-80 THERE FROM 06-12Z. SOME OF THE STORMS COULD BECOME STRONG TO SEVERE LATE TONIGHT...BUT MID LEVEL LAPSE RATES AND DO NOT LOOK IMPRESSIVE SO HAIL SIZES SHOULD REMAIN AT OR BELOW SEVERE LIMITS. THE UPPER LOW WILL LINGER OVER THE SW THROUGH TOMORROW KEEPING AT LEAST HIGH POPS IN PLACE ALONG AND EAST OF I35. THE UPPER LOW WILL FINALLY MOVE INTO THE MISS RIVER VALLEY LATE WED...SO HAVE KEPT AT LEAST SCHC POPS OVER THE EAST THROUGH MID WEEK. AN UPPER RIDGE IS THEN EXPECTED OVERHEAD BY LATE NEXT WEEK THROUGH NEXT WEEKEND. THE ECMWF WOULD RESULT IN VERY LITTLE RAIN CHANCES FOR ANY OF OUR FA AS IT BUILDS THE RIDGE ALL THE WAY THROUGH CENTRAL OK...WHILE THE GFS KEEPS IT SHUNTED SOUTH. REGARDLESS...IT LOOKS WARMER AND DRIER (LOW TO NO POPS) THROUGH NEXT WEEKEND ACROSS MOST OF OUR FA. && .PRELIMINARY POINT TEMPS/POPS...
