A large upper trough became cut off from the flow across the Southern High Plains. This brought favorable wind shear over much of western north Texas, but due to widespread cloud cover, instability was marginal.

Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
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 western north Texas, but due to widespread cloud cover, instability was marginal. Still, at least one severe thunderstorm occurred during the late afternoon with optimal heating.
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 May 26, 5:27 PM CST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 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...
