The episode as NWS PSR wrote it up.

Scattered thunderstorms developed across portions of south central Arizona during the morning hours on July 26th, and they continued into the afternoon. The storms affected southern Gila county, including areas from Globe to San Carlos, and also affected eastern portions of the greater Phoenix metropitan area including Apache Junction. The storms produced gusty and damaging winds estimated to be in excess of 60 mph as well as locally heavy rainfall with rain rates at least one inch per hour. The storms led to the issuance of a variety of products including Severe Thunderstorm Warnings and Urban and Small Stream Flood Advisories.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
936 AM MST FRI JUL 26 2013

.SYNOPSIS...
MOIST SOUTHEASTERLY FLOW WILL KEEP A CHANCE FOR SHOWERS AND
THUNDERSTORMS IN THE FORECAST THROUGH SATURDAY...WITH THE BEST
CHANCES FOR STORMS TO BE IN THE AFTERNOONS AND EVENINGS TODAY.
SOUTHWESTERLY FLOW WILL THEN START A DRYING TREND ON SUNDAY...WHICH
IS EXPECTED TO CONTINUE THROUGH MOST OF NEXT WEEK...WITH THE MONSOON
MOISTURE BEING PUSHED OFF WELL TO OUR EAST.

&&

.DISCUSSION...
STORM ACTIVITY ACROSS THE FORECAST AREA HAS LIFTED MOSTLY TO THE
NORTH INTO YAVAPAI AND MOHAVE COUNTIES IN ARIZONA AND SAN BERNARDINO
IN SE CALIFORNIA THIS MORNING. CLOUDS HAVE BEEN SLOWING CLEARING FROM
SOUTH...WHERE SKIES ACROSS YUMA AND SW MARICOPA COUNTIES ARE MOSTLY
CLEAR. CONTINUED CLEARING WILL AIDE IN DESTABILIZING THE REGION FOR
STORMS LATER IN THE DAY...FIRST GENERATING OVER THE HIGHER TERRAIN
AND THEN PROGGED TO MOVE INTO THE LOWER DESERT ELEVATIONS AS LARGER
SCALE LIFT ACTS UPON THE REGION. VERY MOIST ATMOSPHERE ACROSS THE
REGION...OVER 2 INCHES PWAT ON THE 12Z PHOENIX WX BALLOON. PRIMARY
STORM THREATS TODAY WILL REMAIN HEAVY RAINFALL THAT COULD LEAD TO
LOCALIZED FLOODING IMPACTS AND TO A LESSER EXTENT GUSTY OUTFLOW
WINDS AND BLOWING DUST.

WITH THE MORE LIMITED PRESENCE OF SHOWERS AND CLOUDS THIS MORNING AS
COMPARED TO LAST...TEMPERATURES ARE ANYWHERE FROM 5 TO 10 DEGREES
WARMER ACROSS MUCH OF THE AREA. DEWPOINTS HAVE ALSO SEEN A FEW
DEGREE BOOST TODAY...WITH MANY LOCALES ACROSS THE REGION IN THE LOW
70S. STILL TRACKING THE INTERACTION BETWEEN THE TRANSITORY UPPER
RIDGE TO OUR NORTH AND THE PERSISTENT INVERTED TROUGH MOVING OUT OF
THE GULF OF CALIFORNIA THIS MORNING UP INTO THE LOWER COLORADO RIVER
VALLEY. PLENTY OF DIVERGENT UPPER LEVEL FLOW AT 500 AND 300MB IN
PROXIMITY TO THE RIDGE AXIS TO HELP GEN UP CONVECTIVE ACTIVITY AGAIN
THIS AFTERNOON. STEERING FLOW THROUGH THE COLUMN WILL TRANSITION
FROM SOUTHEASTERLY TO SOUTHERLY THROUGH THE DAY...STILL FCST IN THE
10 TO 20KT RANGE. WILL CONTINUE TO WATCH FOR
DEVELOPMENT...ESPECIALLY IN THE AREAS OF CLEARING CLOUDS...ACROSS
SOUTHERN ARIZONA THROUGH THE DAY. MINOR TIMING ADJUSTMENTS WERE MADE
TO THE POP AND WX FORECAST WITH ADDITIONAL CHANGES TO SKY COVER AND
DEWPOINTS TO MATCH UP WITH CURRENT TRENDS.

&&

.PREVIOUS DISCUSSION /ISSUED AT 300 AM MST/PDT/...
INVERTED TROF CONTINUED TO MOVE WEST/NORTHWESTWARD INTO SWRN AZ AND
SERN CA EARLY THIS MORNING...AND IT SPREAD ADDITIONAL MOISTURE INTO
THE AREA...MAKING A WET AIRMASS EVEN WETTER. PWAT VALUE FROM THE
RECENT 03Z SOUNDING AT PHOENIX ROSE TO AN EVEN 2 INCHES. THIS
FEATURE LED TO NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS THE CENTRAL
DESERTS YESTERDAY MORNING AND AFTERNOON...AND IT WILL LEAD TO
ELEVATED SHOWER AND THUNDERSTORMS CHANCES ACROSS MUCH OF THE CWA
INCLUDING THE SERN CA AND WESTERN AZ DESERTS TODAY. POPS WERE RAISED
TO 20 PERCENT OR HIGHER OVER MOST OF THE DESERTS TODAY...AND OTHER
FACTORS SUPPORTING THE INCREASED POPS ARE FAVORABLE 15-20K SELY
STEERING FLOW COMBINED WITH MODEST DEFORMATION/DIFLUENCE ALOFT. IR
IMAGERY AT 2 AM SHOWED MOSTLY CLOUDY SKIES ACROSS THE AREA...AND
RADAR INDICATED A FEW LIGHT SHOWERS OR VIRGA STILL PRESENT OVER
PORTIONS OF THE WESTERN DESERTS. CLOUDS AND PRECIP SHOULD LEAD TO
ANOTHER DAY OF BELOW SEASONAL NORMAL HIGH TEMPERATURES...WE ARE
GOING WITH A HIGH OF JUST 101 AT PHOENIX TODAY COMPARED TO THE
NORMAL OF 105.

MODEL GUIDANCE REMAINS IN VERY GOOD AGREEMENT IN CALLING FOR A
CHANGE IN THE WEATHER PATTERN THIS WEEKEND INTO THE MIDDLE PORTION
OF NEXT WEEK...MAINLY A DRYING PATTERN AS SOUTHWESTERLY FLOW ALOFT
SETS IN ACROSS SERN CA AND MUCH OF WEST AND CENTRAL ARIZONA. OVER
THE WEEKEND AN UPPER LEVEL LOW IS FORECAST TO SLOWLY APPROACH THE
CALIFORNIA COAST...AND AS THIS OCCURS THE UPPER HIGH SHIFTS OFF
TOWARDS THE SOUTH AND EAST ALLOWING SWLY FLOW ALOFT TO SPREAD ACROSS
MOST OF THE CWA. IN ADDITION TO THIS BEING A VERY UNFAVORABLE
DIRECTION FOR BRINGING STORMS INTO THE DESERT IT TYPICALLY LEADS TO
DRIER AIR ADVECTING INTO THE LOWER DESERTS...MINIMIZING THE CHANCES
FOR ANY STORMS TO SPONTANEOUSLY DEVELOP OVERHEAD. AS A RESULT...WE
HAVE A DECREASING POP/WEATHER TREND FROM THE WEST THIS WEEKEND AND
BY SUNDAY AFTERNOON THUNDERSTORM CHANCES WILL BE CONFINED TO AREAS
EAST OF THE LOWER CO RIVER VALLEY. POPS OVER THE AZ DESERTS WILL
LOWER TO BELOW 15 PERCENT MOST PLACES...WITH HIGHER VALUES CONFINED
TO HIGHER TERRAIN AREAS EAST OF PHOENIX. DESPITE THE DRYING...H5
HEIGHTS LOWER TO AROUND 588DM...SO HIGH TEMPS WILL STAY NEAR OR
SLIGHTLY BELOW SEASONAL NORMALS....WITH 104 FORECAST AT PHOENIX BOTH
SATURDAY AND SUNDAY.

FOR THE MONDAY THROUGH WEDNESDAY TIME PERIOD...ALTHOUGH THE LOW OFF
THE CA COAST WEAKENS AND EVENTUALLY LIFTS INLAND...A DRYING SWLY
FLOW ALOFT CONTINUES ACROSS SERN CA AND MOST OF ARIZONA. THIS
CONTINUES TO ERODE MOISTURE...WITH PWAT VALUES DROPPING TO NEAR OR
BELOW ONE INCH OVER THE DESERTS. THREATS FOR THUNDERSTORMS WILL BE
CONFINED TO THE HIGHER TERRAIN EAST OF PHOENIX...OVER SRN GILA
COUNTY...EACH DAY WITH POPS MOSTLY LESS THAN 20 PERCENT. EXPECT
MOSTLY SUNNY DAYS AND MOSTLY CLEAR NIGHTS FOR THE MOST PART ACROSS
THE DESERTS. HIGH TEMPS WILL START TO WARM AS H5 HEIGHTS RISE AND
THE ATMOSPHERE DRIES...AND BY WEDNESDAY THE HOTTER LOWER DESERTS
WILL APPROACH 110 DEGREES.

BY NEXT THURSDAY THE SWLY FLOW BEGINS TO WEAKEN AND BOTH THE GFS AND
ECMWF INDICATE A RETURN TO SELY STEERING FLOW INTO SOUTH CENTRAL
ARIZONA. THEY ALSO SUGGEST AN INVERTED TROF WILL MIGRATE INTO SERN
AZ AND WILL LEAD TO AN INCREASE IN THUNDERSTORMS CHANCES ACROSS THE
CENTRAL DESERTS FOR THE AFTERNOON AND EVENING HOURS. POPS OUT WEST
WILL REMAIN LOW AND IN THE SINGLE DIGITS AS THE AIRMASS REMAINS TOO
DRY AND STABLE FOR ANY SIGNIFICANT CONVECTION TO DEVELOP.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA...INCLUDING KPHX...KIWA AND KSDL...
LEFT-OVER DEBRIS CLOUDS FROM THURSDAY/S THUNDERSTORM ACTIVITY TO
KEEP BKN-OVC MID AND HIGH-LEVEL CIGS OVER THE PHX AREA TERMINALS
THROUGH AT LEAST MID-DAY...WITH AT LEAST SOME EARLY AFTERNOON
CLEARING LIKELY. CONVECTIVE ACTIVITY IS ONCE AGAIN EXPECTED TO
DEVELOP OVER THE REGION THIS AFTERNOON AND EVENING...WILL KEEP VCSH
IN THE TAFS TO REFLECT THE POSSIBILITY OF THIS CONVECTION ACTUALLY
REACHING THE TERMINALS. WINDS TO FAVOR TYPICAL DIURNAL
PATTERNS...WITH SPEEDS MAINLY AOB 12KTS.

SOUTHEAST CA AND SOUTHWEST AZ...INCLUDING KIPL AND KBLH...
OFF AND ON MID AND HIGH CLOUDS ARE EXPECTED THROUGH THE PERIOD WITH
HIGH BASED CU DURING THE AFTERNOON AND EARLY EVENING. THERE IS A
SLIGHT CHANCE THAT THUNDERSTORMS COULD AFFECT THE TERMINALS THIS
AFTERNOON OR EVENING...BUT CONFIDENCE IS TOO LOW TO INCLUDE IN THE
TAFS...AT THIS TIME. WINDS TO FAVOR A SOUTHERLY DIRECTION
THROUGH THE TAF PERIOD AT BOTH KIPL AND KBLH...WITH SPEEDS MAINLY
AOB 10KTS.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SUNDAY THROUGH THURSDAY...
LOW PRESSURE MOVING VERY SLOWLY INLAND INTO CENTRAL CA AND THE GREAT
BASIN WILL PUSH MUCH DRIER AIR INTO THE REGION...REDUCING MONSOON
THUNDERSTORM ACTIVITY TO JUST SOME ISOLATED CELLS OVER THE HIGHER
TERRAIN NORTH AND EAST OF PHOENIX. MINIMUM HUMIDITY VALUES WILL FALL
INTO THE LOW TO MID TEENS OVER THE LOWER DESERTS...WITH FAIR TO GOOD
OVERNIGHT RECOVERIES. WINDS TO FAVOR THE USUAL DIURNAL TRENDS...WITH
SOME AFTERNOON AND EARLY EVENING GUSTINESS...ESPECIALLY OVER THE
HIGHER TERRAIN.
