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.
The nearest sounding before it
Phoenix, AZ (KPSR), launched 00:00Z, 0.9 hours before the alert went out and 44 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

MEYERSWhat 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 Sep 12, 3:05 PM MST, 2 hours 47 minutes earlier.
Area forecast discussion, Sep 12, 3:05 PM MST, 2 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 305 PM MST SAT SEP 12 2015 .SYNOPSIS... SEVERAL PACIFIC DISTURBANCES WILL MOVE INTO THE REGION SUNDAY THROUGH TUESDAY...WITH A MODEST INCREASE IN MOISTURE AND CHANCES FOR SHOWERS OR THUNDERSTORMS. THESE DISTURBANCES WILL ALSO ALLOW TEMPERATURES TO FALL SLIGHTLY BELOW AVERAGE DURING THE FIRST PAST OF THE WEEK. A MUCH DRIER AND STABLE AIRMASS WILL RETURN FOR THE LATTER HALF OF NEXT WEEK. && .DISCUSSION... AFTERNOON WV IMAGERY DEPICTS AN INCREASINGLY COMPLICATED SCENARIO WITH A PRONOUNCED CIRCULATION CENTER AND DIVERGENT JET SIGNATURE APPROACHING THE CNTRL CALIFORNIA COAST...BUT LARGELY DOWNSTREAM CONFLUENT SHEARED NORTHWEST FLOW THROUGHOUT ARIZONA. HOWEVER...A SUBTLE SHORTWAVE APPEARS TO BE DROPPING SOUTH FROM THE FOUR CORNERS AREA...AIDING IN LARGER SCALE SYNOPTIC ASCENT ACROSS THE MOGOLLON RIM...WHITE MOUNTAINS...AND PORTIONS OF SRN GILA COUNTY. 12Z REGIONAL SOUNDING DATA SAMPLED PWATS AROUND 1.40 INCHES...HOWEVER ONLY MODEST 10-11 G/KG IN THE SFC-H8 LAYER...AND MORE NOTABLE MOISTURE AROUND THE H7 LAYER. ONE OF THE MORE INTERESTING ASPECTS OF THIS AFTERNOONS ANALYSIS IS UNUSUALLY COOL TEMPERATURES AT THE H5 LEVEL (-8C TO -9C) AND VERY STEEP MIDLEVEL LAPSE RATES (H7-H5 7-8 C/KM). GIVEN THE BOUNDARY LAYER FLOW AND LIMITED MOISTURE IN THE SFC-H8 LAYER...EFFICIENT MIXING HAS ALLOWED SFC DEWPOINTS TO FALL INTO THE UPPER 40S IN SERN ARIZONA...TO MIDDLE 50S IN CNTRL ARIZONA. THESE READINGS MAY MAKE SURVIVAL OF DEEP CONVECTION INTO LOWER ELEVATION LOCATIONS DIFFICULT (IF NOT IMPOSSIBLE)...EVEN WITH MORE ORGANIZED OUTFLOWS. HOWEVER...WITH LARGE INVERTED-V PROFILES AND DCAPE VALUES 1200-1500 J/KG...CANNOT COMPLETELY DISCOUNT SOME STRONGER LONG TRAVELING OUTFLOWS IMPACTING LOW ELEVATIONS (I.E. PHOENIX METRO). OTHERWISE...SHOWER ACTIVITY IN SERN CALIFORNIA ASSOCIATED WITH A SLUG OF MIDLEVEL MOISTURE (IN AN OTHERWISE CONVECTIVELY LIMITED ENVIRONMENT) WILL CONTINUE TO LIFT NORTH THIS EVENING. THIS FIRST IN A SERIES OF SHORTWAVES WILL LIFT INTO WRN ARIZONA SUNDAY...ALLOWING SOME MEASURE OF SLY LOW LEVEL FLOW AND MOISTURE ADVECTION. HOWEVER...AS THIS OCCURS...MODELS ARE IN EXCELLENT AGREEMENT DEPICTING SUBSTANTIAL WARM ADVECTION ALOFT WITH MIDLEVEL LAPSE RATES ONCE AGAIN BECOMING MORE MOIST ADIABATIC (5.5-6.0 C/KM). WHILE BOUNDARY LAYER MOISTURE MAY REALIZE A SOMEWHAT HIGHER MAGNITUDE THAN MODEL FORECAST SOUNDINGS DEPICT...AT THIS TIME ONLY 8- 10 G/KG IS SUGGESTED YIELDING MLCAPES ONLY IN A 50-200 J/KG RANGE. JET DIVERGENCE FIELDS WILL ALSO BE MOST ROBUST OVER NRN ARIZONA WITH MORE ANTI-CYCLONIC FLOW ENTERING FAR SWRN ARIZONA...YET SREF PROBABILITIES AND A FAIR SUBSET OF HIGH RESOLUTION MODELS STILL SUPPORT SCT STORMS DURING PEAK HEATING WITH DEEP INVERT-V SOUNDINGS AND GUSTY WINDS POSSIBLE. MODEL TIMING OF FOLLOW UP PACIFIC SHORTWAVES MONDAY AND TUESDAY ARE STILL CHANGING SLIGHTLY WITH EACH MODEL RUN. HOWEVER...MODELS ARE STILL CONSISTENT WITH FORECASTS OF MODERATELY STRONG 850/700 20-30 KT SOUTHERLY WINDS IN FAR WESTERN ARIZONA (PARTICULARLY MONDAY)...AND GOOD VEERING WIND PROFILES WITH HEIGHT. IN ADDITION... SYNOPTIC SCALE ASCENT WOULD BE FAVORED WITH GRADUALLY FALLING HEIGHTS ALOFT AND INCREASING JET ENERGY. HOWEVER...ONE MAJOR DETRIMENT TO CONVECTIVE ACTIVITY AND RAINFALL APPEARS TO BE ADDITIONAL WARMING ALOFT...SUCH THAT H5 TEMPERATURE REACH -5C AND CREATE VERY STRONG CAPPING ALOFT AND SEVERELY HINDERED LAPSE RATES. MODEL SOUNDINGS SHOW THE INCREASES LOW LEVEL MOISTURE RELATED TO THE STRONGER SLY FLOW...HOWEVER NO PLACE TO LIFT THIS MOISTURE. IN THE END...THIS TIME FRAME MAY END UP WITH A LOT OF MID CLOUDS ALONG A QUASI-FRONTAL BOUNDARY...BUT NOT MUCH MORE THAN A FEW SHOWERS. CONFIDENCE IN THE OVERALL EVOLUTION OF THIS PERIOD IS QUITE LOW...AND KEPT POPS SOMEWHAT RESTRICTED. WEDNESDAY THROUGH SATURDAY... ALTHOUGH STRONG UPPER LEVEL SOUTHWEST WINDS WILL PERSIST OVER THE FORECAST AREA...DUE TO ADDITIONAL PACIFIC SHORTWAVES FLOWING WELL NORTH OF THE AREA...MODELS INSIST THAT STABLE AND WARM WEATHER IS IN THE OFFING. FORECASTER CONFIDENCE IS LOW FOR THIS PERIOD...THEREFORE NO SHOWER THREATS WILL BE MENTIONED. AFTN TEMPS THESE DAYS SHOULD BE NEAR NORMAL. && .AVIATION... SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL... THUNDERSTORM ACTIVITY WILL TEND TO REMAIN OUTSIDE OF METRO PHOENIX FAVORING YAVAPAI...GILA...PINAL...AND WESTERN PIMA COUNTIES. HOWEVER A STRAY STORM OVER THE VALLEY FLOOR IS ENTIRELY POSSIBLE...ESPECIALLY FOR KIWA. THUS INSERTED VCTS IN PHOENIX AREA TAFS. OUTFLOW WINDS ARE ALSO POSSIBLE BUT CONFIDENCE TOO LOW AT THIS POINT TO INSERT TEMPO GROUPS WITH STRONG WINDS. IF PINAL AND PIMA COUNTIES ONLY HAVE ISOLATED ACTIVITY THEN POTENTIAL FOR OUTFLOWS AND BLOWING DUST AFFECTING TAF SITES WILL BE LOW. ANTICIPATE REGIONAL STORM ACTIVITY TO DISSIPATE WELL BEFORE MIDNIGHT. OTHERWISE...ANTICIPATE WESTERLY SURFACE WINDS TO PREVAIL INTO THE EVENING BEFORE TRENDING TOWARD EASTERLY DIRECTIONS LATER THIS EVENING. SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH... BAND OF THICK MID-HIGH CLOUDS...BASES GENERALLY ABOVE FL100...WITH EMBEDDED SHOWERS WILL START DECREASING FROM SOUTHWEST TO NORTHEAST AFTER 00Z. ISOLATED THUNDERSTORMS ARE ALSO POSSIBLE...ESPECIALLY OVER LA PAZ COUNTY WHERE SURFACE HEATING HAS BEEN MUCH BETTER. THERE IS ALSO THUNDERSTORM POTENTIAL TO THE WEST OF THE FORECAST AREA OVER THE HIGHER MOUNTAINS OF SAN DIEGO AND WESTERN RIVERSIDE COUNTIES...EXPECT THOSE STORMS TO DISSIPATE AWAY FROM HIGHER TERRAIN. ANTICIPATE REGIONAL STORM ACTIVITY TO DISSIPATE WELL BEFORE MIDNIGHT. OTHERWISE...SURFACE WINDS WILL FOLLOW FAMILIAR DIURNAL PATTERNS. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... TUESDAY THROUGH SATURDAY... LINGERING MOISTURE WILL KEEP SLIGHT THUNDERSTORM CHANCES GOING TUESDAY...MAINLY EAST OF THE LOWER COLORADO RIVER VALLEY. MOISTURE WILL DECLINE WEDNESDAY ONWARD FOR REMOVAL OF STORM CHANCES. WITH DRIER AIR...MINIMUM HUMIDITIES WILL DECLINE WITH MOST LOWER ELEVATIONS DROPPING BELOW 20 PERCENT BY FRIDAY. OVERNIGHT RECOVERY DECLINES AS WELL BUT REMAINS GOOD. TEMPERATURES WILL BE BELOW NORMAL TUESDAY FOLLOWED BY A SLOW WARMING TREND.
