The radar

The Phoenix radar (KIWA), 77 km from the middle of the area, began a volume at 21:34 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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

Flgstf/Belemont, AZ (KFGZ), launched 12:00Z, 9.5 hours before the alert went out and 166 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.

Area forecast discussion, Oct 6, 2:20 PM MST, 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
220 PM MST TUE OCT 6 2015

.SYNOPSIS...
DEEP LOW PRESSURE WILL CONTINUE GRADUALLY MOVING ACROSS THE DESERT
SOUTHWEST THROUGH WEDNESDAY. THIS WILL RESULT IN CONTINUED UNSETTLED
CONDITIONS TODAY WITH SHOWERS AND THUNDERSTORMS...MAINLY EAST OF THE
LOWER COLORADO RIVER VALLEY. DECREASING MOISTURE AND CLEARING SKIES
ARE EXPECTED STARTING WEDNESDAY...WITH NEAR TO SLIGHTLY ABOVE NORMAL
TEMPERATURES TOWARD THE END OF THE WEEK AND INTO THE WEEKEND.

&&

.DISCUSSION...
SLOW PROGRESSION OF THE POTENT UPPER LEVEL LOW PRESSURE SYSTEM
CONTINUES THIS AFTERNOON ACROSS NORTH-CENTRAL AZ. AMDAR UL WIND
FIELDS AND EARLY AFTN SATELLITE LOOPS PLOT THE LOW CIRC CENTER
SPANNING ACROSS MOHAVE/YAVAPAI COUNTIES WITH LINES OF
SHOWER/THUNDERSTORM ACTIVITY ALONG ASCENT REGIONS/VORTICITY
LOBES...ONE STRETCHING SW THROUGH YUMA AND MARICOPA COUNTIES AND AN
ADDITIONAL LINE OF ENHANCED STORM ACTIVITY ACROSS EASTERN AZ FROM
TUCSON THROUGH SHOW LOW. FAVORABLE SHEAR PROFILE REMAINS IN THE
BALLPARK OF 20-30KTS OVER SOUTH-CENTRAL AZ AND UNIDIRECTION INFLOW
WINDS HAVE HELPED STORM PROPAGATION AND UPDRAFT DEVELOPMENT SO FAR
THIS AFTERNOON.

LAPSE RATES QUICKLY STEEPENED IN THE WAKE OF THE MID-TROP FRONT/VORT
LOBE MOVING THROUGH WESTERN AZ AND STORM ACTIVITY DEVELOPED SHORTLY
AFTER OVER THE SW AZ DESERTS IN THE LATE AM. THE HEAVIEST
STORMS...AS OF THIS WRITING...WERE MOVING NORTHWARD ACROSS THE PHX
METRO AND INTO YAVAPAI COUNTY WITH AN ADDITIONAL UPWARD PULSE MOVING
TOWARDS MARICOPA/CASA GRANDE. ADDITIONAL SHOWER AND VERY ISO STORM
ACTIVITY WAS STILL FILLING BACK IN ACROSS SOUTHWEST MARICOPA/PINAL
COUNTY...MOST NOT TO THE INTENSITY THAT WAS OBSERVED EARLIER IN THE
DAY. WITH SUBSIDENCE WAKE FLOW BEGINNING TO NOSE INTO FAR WESTERN AZ
AND ALREADY ESTABLISHED OVER SOUTHEAST CA...THE POP GRADIENT WILL
CONTINUE TO TIGHTEN FOR THE REST OF THE AFTERNOON AND EVENING...WITH
THE OVERALL MOTION OF THE ACTIVITY GRADUALLY TRANSLATING EASTWARD.
CHANCE FOR RAIN SHOWERS AND SLIGHT CHANCE FOR ANY LINGERING RUMBLES
OF THUNDER WILL CONTINUE FOR MARICOPA COUNTY EASTWARD INTO THE EARLY
EVENING...WITH A FAIR BIT OF THE ACTIVITY LOSING ITS PUNCH AFTER
SUNSET. CLEARER SKIES AND MORE OPPORTUNITY FOR WARMING HAS ALLOWED
DAYTIME TEMPERATURES TO WARM JUST SHY OF NORMAL FOR THE WESTERN
FORECAST ZONES...WHILE MUCH COOLER TEMPERATURES REMAIN OVER THE
SOUTH-CENTRAL AZ DESERTS.

THE UL LOW WILL CONTINUE TO SLOWLY TRACK EASTWARD ACROSS CENTRAL AZ
PERSISTING THE COOLER TEMPERATURES ALOFT WITH 500MB TEMPERATURES
NEARING MINUS 14-15C FOR WEDNESDAY. WITH PERSISTENT COOLING AND
LINGERING LL MOISTURE FIELDS...THERE WILL STILL BE A DECENT CHANCE
OF SOME SHOWERS AND THUNDERSTORMS OVER HIGHER TERRAIN AREAS EAST OF
PHOENIX DURING THE DAY ON WEDNESDAY...BUT BY LATE WEDNESDAY NIGHT
THE RAIN THREAT SHOULD END ACROSS OUR AREA. WHAT DOESN'T RESULT AS
PRECIP ACTIVITY WILL FILL IN ACROSS THE FORECAST AREA IN THE FORM
SIGNIFICANT CU FIELDS BEFORE WAKE SUBSIDENCE ROTATES INTO THE AREA
FROM THE NORTH...DISSIPATING THE CLOUD COVER. THE UPPER LOW WILL
CONTINUE TO MOVE SOUTHEASTWARD INTO MEXICO ON THURSDAY WHILE RIDGING
ALOFT FROM THE PACIFIC WILL START TO OVERTAKE THE DESERT SOUTHWEST.

TEMPERATURES THROUGH THE REST OF THE WEEK WILL VARY QUITE A BIT WITH
AREAWIDE HIGHS TODAY ONLY IN THE LOWER TO MIDDLE 80S ACROSS THE
DESERTS. AS RIDGING ALOFT TAKES OVER AND HEIGHTS DRAMATICALLY
INCREASE BY LATE THIS WEEK...HIGHS WILL INCREASE EACH DAY...REACHING
NORMALS OR SLIGHTLY ABOVE ON THURSDAY AND THEN WIDESPREAD 95-100
DEGREE HIGHS OVER THE DESERTS FROM FRIDAY INTO EARLY NEXT WEEK. LONG
RANGE MODEL OUTPUT SHOWS REMARKABLY GOOD AGREEMENT IN CYCLING THE
SAME UPPER LOW BACK WESTWARD THROUGH NORTHERN MEXICO AND THE BAJA
PENINSULA THIS WEEKEND...SETTLING OVER THE EASTERN PACIFIC FOR EARLY
NEXT WEEK. IF THIS SOLUTION PANS OUT IT MAY AGAIN BRING IN INCREASED
MOISTURE SOMETIME EARLY NEXT WEEK AND A RETURN OF RAIN CHANCES.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...KSDL...

A COLD LOW PRESSURE SYSTEM WILL MOVE BODILY INTO CENTRAL ARIZONA
FROM SOUTHERN CA TODAY. UNSETTLED CONDITIONS ARE EXPECTED THROUGH
03Z WED...I.E. CIGS 5-7 THSD AGL WITH SCT SHWRS AND AFTN TSTMS.
SIGNIFICANT ATMOSPHERIC VERTICAL WIND SHEAR THIS AFTERNOON MAY PLAY
A ROLE IN POSSIBLY GENERATING ISOLATED SEVERE TSTMS...STRONG SFC
WIND GUSTS...AND LARGE HAIL.

SOUTHEAST CALIFORNIA/SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...

A COLD LOW PRESSURE SYSTEM WILL MOVE EAST INTO CENTRAL ARIZONA
TODAY. HOWEVER SCT TO BKN CLDS 8 TO 10 THSD AGL WITH ISOLATED SHWRS
