Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Phoenix, AZ wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 26, 2:06 PM MST, 2 hours 4 minutes earlier.
Area forecast discussion, Aug 26, 2:06 PM MST, 2 hours 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 206 PM MST FRI AUG 26 2011 .SYNOPSIS... ABOVE NORMAL TEMPERATURES WILL CONTINUE ACROSS THE REGION THROUGH EARLY NEXT WEEK...AS A STRONG HIGH PRESSURE SYSTEM BECOMES STATIONARY. AN EXCESSIVE HEAT WARNING IS POSTED FOR THE LOWER DESERTS OF ARIZONA AND SOUTHEAST CALIFORNIA THROUGH MONDAY EVENING. ENOUGH MOISTURE COVERS THE REGION FOR A CHANCE OF LATE AFTERNOON AND EVENING THUNDERSTORMS...MAINLY OVER THE MOUNTAINS THROUGH THE WEEKEND. COOLER TEMPERATURES WITH MORE MONSOON MOISTURE WILL RETURN NEXT WEEK. && .DISCUSSION... EARLY AFTERNOON RADAR MOSAIC REVEALS SCATTERED SHOWERS AND THUNDERSTORMS OVER THE AREA. THE MAJORITY OF THE ACTIVITY HAS BEEN CONFINED TO THE HIGHER TERRAIN EAST OF PHOENIX...AS WELL AS TO THE SOUTH ACROSS PIMA COUNTY. SOME STORMS HAVE DRIFTED INTO THE SOUTHEAST VALLEY OF THE PHOENIX METRO AREA...BUT THUS FAR THEY HAVE REMAINED BELOW SEVERE THRESHOLDS. STORMS HAVE DEVELOPED QUICKLY...BUT STRUGGLE ONCE REACHING THE LOWER DESERTS. SPC MESOANALYSIS SHOWS A WEAK CAP /100 J/KG CIN/ IN PLACE AS OF 2PM...MODELS KEEP THIS CAP IN PLACE BUT WEAKEN IT AROUND 00Z. I COULD ENVISION SOME STORMS DRIFTING THROUGH THE AREA BUT THE MAIN THREATS WOULD PROBABLY BE GUSTY WINDS AND BRIEF HEAVY RAIN. I BUMPED POPS UP JUST A BIT TO 40 PERCENT AS I DON\T ANTICIPATE WIDESPREAD CONVECTION...BUT JUST ENOUGH TO WARRANT SCATTERED WORDING. I ALSO THINK THE PIMA COUNTY CONVECTION WILL MAINTAIN ITSELF AND MOVE THROUGH WESTERN ARIZONA/SOUTHEAST CALIFORNIA LATER THIS EVENING. POPS WERE RAISED IN THESE AREAS EARLIER TODAY AND THIS STILL LOOKS REASONABLE. PRECIP CHANCES ON SATURDAY LOOK BETTER TO THE WEST OF PHOENIX THAN TO THE EAST...AS SREF MLCAPE PROBABILITIES KEEP AN AXIS OF INSTABILITY IN PLACE ALONG THE LOWER COLORADO RIVER VALLEY. IN ADDITION...MODELS SHOW AN UPPER TROUGH ROTATING THROUGH BAJA CALIFORNIA INTO SOUTHERN CALIFORNIA SATURDAY AFTERNOON. THIS WOULD SEEM TO BE ENOUGH TO TRIGGER AFTERNOON SHOWERS/THUNDERSTORMS AND I\LL KEEP POPS THE HIGHEST POPS IN PLACE OUT WEST. OTHERWISE NO MAJOR CHANGES MADE TO POPS. FORECAST TEMPERATURES REMAIN ON TRACK IN THE 112-114 RANGE THROUGH MONDAY. I EXTENDED THE EXCESSIVE HEAT WARNING UNTIL MONDAY AT 8PM. AT THIS POINT TUESDAY LOOKS MARGINAL FOR HEAT WARNING CRITERIA...BUT IS ONLY WITHIN A DEGREE OR TWO. MOISTURE WILL RETURN TO THE AREA STARTING ON TUESDAY WHICH SHOULD HELP KEEP TEMPS DOWN A BIT. && .PREVIOUS DISCUSSION... TUESDAY THROUGH THURSDAY... ATMOSPHERIC THICKNESS AND MORE MONSOON MOISTURE SHOULD BEGIN TO REDUCE AFTERNOON TEMPERATURES BELOW EXCESSIVE HEAT CRITERIA...AND CLOSER TO NORMAL VALUES. THERE WILL ALSO BE AN INCREASED CHANCE OF AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS ACROSS SOUTHWEST AND SOUTH CENTRAL AZ AS WEAK DISTURBANCES COME FLOWING NORTH OUT OF MEXICO. && .AVIATION... SOUTH-CENTRAL ARIZONA...INCLUDING KPHX AND KIWA... MODEST LOW LEVEL MOISTURE IN COMBINATION WITH HOT TEMPERATURES TODAY WILL LEAD TO ISOLATED THUNDERSTORMS ACROSS THE REGION TODAY. INSTABILITY SHOULD BE ENOUGH FOR THE POTENTIAL FOR SOME GUSTY WINDS AND BLOWING DUST ASSOCIATED WITH THUNDERSTORM OUTFLOWS...BUT NOT ANTICIPATING WIDESPREAD COVERAGE. VISIBILITIES ASSOCIATED WITH ANY BLOWING DUST COULD DROP CONDITIONS TO IFR FOR A BRIEF TIME. THUNDERSTORMS ARE EXPECTED TO BE WINDING DOWN BY LATE EVENING WITH LINGERING HIGH CLOUDS AND LIGHT WINDS THROUGHOUT THE OVERNIGHT HOURS. SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA...INCLUDING KIPL AND KBLH... THERE WILL BE SOME MID/HI LEVEL DEBRIS CLOUDS THIS MORNING...WITH SOME HIGHER BASED CU TO DEVELOP IN THE AFTERNOON. MOISTURE AND INSTABILITY ARE SOMEWHAT ELEVATED AND THERE IS A SLIGHT CHANCE FOR AN AFTERNOON OR EVENING THUNDERSTORM...WITH THE BETTER THREAT EXPECTED AT KBLH AFTER 7 PM. WILL MENTION CB IN THE TAF AT KBLH THIS EVENING...AS CONVECTION FORMING OVER HIGHER TERRAIN OF LA PAZ COUNTY MAY SPREAD WESTWARD AND SEND SOME GUSTY OUTFLOW WIND OR BLOWING DUST INTO THE BLYTHE AREA DURING THE MID OR EVEN LATE EVENING HOURS. && .FIRE WEATHER... MONDAY THROUGH FRIDAY... CONTINUED HOT AND FAIRLY DRY CONDITIONS WILL PERSIST INTO NEXT WEEK WITH WELL ABOVE NORMAL TEMPERATURES EXPECTED. MINIMUM RH VALUES WILL RANGE FROM THE 20S AND 30S IN THE EASTERN HIGHER TERRAIN TO THE TEENS ACROSS THE LOWER DESERTS. WINDS WILL GENERALLY REMAIN LIGHT AND VARIABLE THROUGH THE PERIOD WITH THE EXCEPTION OF SOME POSSIBLE GUSTY WINDS DURING THE AFTERNOON HOURS. && .CLIMATE... THE AVERAGE TEMPERATURE FOR 1-24 AUGUST AT PHOENIX...97.4 F...IS THE WARMEST ON RECORD (NEXT WARMEST: 96.2 F IN 1986). AT YUMA...THE AVERAGE TEMPERATURE OF 96.7 F OBSERVED THIS YEAR IS THIRD WARMEST ON RECORD (WARMER/HOTTER: 97.8 F IN 1994 AND 97.1 F IN 1995). IF CURRENT FORECAST MAX/MIN TEMPS FOR PHOENIX AND YUMA VERIFY... THIS AUGUST WILL BE THE HOTTEST ON RECORD AT BOTH LOCATIONS. PHOENIX RECORDED FOUR CONSECUTIVE DAYS WITH MAX TEMPS AT OF ABOVE 113 F (45 C) AND AVERAGE TEMPERATURE AT OR ABOVE 100 F. NEITHER OCCURRENCE IS VERY COMMON: INCLUDING THE 22-25 AUGUST HEAT WAVE IN THE CLIMATOLOGICAL RECORD FOR PHOENIX...FOUR OR MORE CONSECUTIVE DAYS OF 113+ F MAX TEMPS HAS NOW OCCURRED 13 TIMES...WHILE FOUR OR MORE CONSECUTIVE DAYS OF 100+ F AVERAGE TEMPERATURE HAS OCCURRED 19 TIMES. && .PSR WATCHES/WARNINGS/ADVISORIES...
