The radar

The Flagstaff radar (KFSX), 73 km from the middle of the area, began a volume at 21:06 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

Phoenix, AZ (KPSR), launched 12:00Z, 9.1 hours before the alert went out and 74 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, Jul 12, 1:20 PM MST, 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
120 PM MST FRI JUL 12 2013

&&

.SYNOPSIS...
MOIST MONSOON AIR UNDER FAVORABLE SOUTHERLY FLOW WILL CONTINUE INTO
THIS EVENING...WITH SCATTERED TO NUMEROUS THUNDERSTORMS EXPECTED
OVER SOUTH CENTRAL ARIZONA...WITH ISOLATED THUNDERSTORMS ELSEWHERE.
DRIER AIR WILL BEGIN TO SLIDE INTO THE REGION ON SATURDAY...AND
ESPECIALLY ON SUNDAY AND MONDAY...WITH CHANCES OF SHOWERS AND
THUNDERSTORMS DECREASING EACH DAY. TEMPERATURES WILL BE WARMING TO
NEAR...OR ABOVE NORMAL VALUES NORMAL FOR THIS WEEKEND INTO EARLY
NEXT WEEK.

&&

.DISCUSSION...
AFTER A RATHER QUIET MORNING...A RATHER ACTIVE AFTERNOON
WEATHERWISE APPEARS TO BE ON TAP FOR SOUTH CENTRAL ARIZONA THIS
AFTERNOON AND EVENING. AS DEPICTED ON THE LAST SEVERAL RUNS OF THE
HOURLY HRRR MODEL...A LARGE COMPLEX OF THUNDERSTORMS THAT FORMED
LATE LAST NIGHT OVER NORTHERN SONORA MEXICO HAS HELD TOGETHER QUITE
WELL AND IS NOW PRODUCING A LINE OF STRONG THUNDERSTORMS THAT IS NOW
MOVING ACROSS PINAL COUNTY. THIS COMPLEX OF STORMS APPEARS TO BE
BEING SUPPORTED BY A SHORTWAVE/JET MAX THAT WAS PICKED UP ON THE 12Z
500MB ANALYSIS OVER SOUTHEAST ARIZONA. THESE STORMS HAVE ALREADY
PRODUCED DAMAGING WINDS...BLOWING DUST...SMALL HAIL...AND LOCAL
RAINFALL AMOUNTS IN EXCESS OF 1 INCH OVER PIMA AND PINAL COUNTIES.
LATEST HIGH-RESOLUTION MODEL RUNS TAKE THESE STORMS INTO THE GREATER
PHOENIX AREA THIS AFTERNOON...THEN RAPIDLY WEAKEN THEM THIS EVENING
AS THEY MAKE AN ATTEMPT TO PUSH INTO WESTERN ARIZONA AS THE
SUPPORTING SHORTWAVE RAPIDLY MOVES OFF TO THE NORTH AND WEAKENS.

SATURDAY APPEARS TO BE SETTING UP AS A QUIETER DAY...ESPECIALLY IF
TODAY'S THUNDERSTORM ACTIVITY WORKS OVER THE AIRMASS OVER THE
REGION. MODEL GUIDANCE IS IS GOOD AGREEMENT THAT RIDGING WILL BUILD
BACK WESTWARD INTO THE DESERT SOUTHWEST AS AN UPPER TROF MOVES INTO
THE PACIFIC NORTHWEST. LATEST NAM FORECAST SOUNDINGS DROP THE PWAT
VALUES OVER THE PHOENIX AREA TO AROUND 1.6 INCH ON SATURDAY
AFTERNOON...1.3 INCH ON SUNDAY AFTERNOON...AND 1.1 INCH ON MONDAY
AFTERNOON. CURRENT THINKING IS THAT THUNDERSTORM ACTIVITY WILL BE
CONFINED TO THE HIGHER TERRAIN NORTH AND EAST OF PHOENIX ON
SATURDAY...WITH LITTLE OR NO ACTIVITY ON SUNDAY AND MONDAY.
TEMPERATURES ARE EXPECTED TO WARM EACH DAY...WITH HIGHS APPROACHING
110F BY MONDAY.

ALTHOUGH WE ARE NOT COMPLETELY SOLD ON THE LONG RANGE MODEL
SOLUTIONS FOR THE MIDDLE OF NEXT WEEK...IT DOES LOOK LIKE A FAIRLY
SIGNIFICANT UPPER LOW MAY MAKE IT/S WAY ACROSS THE SOUTHERN PLAINS
INTO NEW MEXICO BY NEXT TUESDAY. IT IS TOO EARLY TO KNOW HOW MUCH
MOISTURE WILL BE AVAILABLE ACROSS THE REGION...BUT IF THIS SOLUTION
PANS OUT...THE MIDDLE OF NEXT WEEK COULD SEE VERY ACTIVE MONSOON
ACTIVITY ACROSS EASTERN ARIZONA AND POSSIBLY INTO THE LOWER DESERTS.
THE OVERALL FLOW DURING THIS TIME WILL LIKELY BE FROM THE NORTHEAST
ACROSS EASTERN ARIZONA AND FROM THE SOUTH ACROSS FAR WESTERN
ARIZONA. A SCENARIO LIKE THIS WOULD LIKELY RESULT IN DRY CONDITIONS
TO THE WEST OF PHOENIX AND AN ACTIVE MONSOON PERIOD ACROSS THE
HIGHER TERRAIN EAST OF PHOENIX. THE LONG RANGE TEMPERATURE OUTLOOK
SHOULD BRING NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES ACROSS OUR
WESTERN ZONES AND NEAR TO SLIGHTLY BELOW NORMAL FOR SOUTH-CENTRAL
AND EAST-CENTRAL ARIZONA.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA...INCLUDING KPHX...KIWA AND KSDL...
CONVECTION TRYING TO WORK ITS WAY INTO THE METRO AREA FROM THE
SOUTH...BUT AS HAS BEEN THE CASE FOR THE PAST FEW DAYS...STORMS SEEM
TO BE DECAYING AS THEY DESCEND INTO THE DESERTS AND ENCOUNTER THE
MID LEVEL CAPPING INVERSION. THAT BEING SAID...HRRR MODEL AND TO
SOME EXTENT THE U-OF-A WRF MODELS TRY AND BRING THIS CONVECTION
INTO THE EAST VALLEY LATER THIS AFTERNOON. INTRODUCED VCSH AT ALL
PHOENIX TAF SITES BETWEEN 19-21Z ALTHOUGH MY CONFIDENCE IN
PREVAILING -SHRA REMAINS LOW. IF NOTHING ELSE...WIDESPREAD CIGS
BETWEEN 6-8KFT ARE LIKELY ACROSS THE AREA THIS AFTERNOON/EVENING.
WINDS WILL REMAIN WESTERLY UNTIL EARLY EVENING...BANKING ON OUTFLOWS
TO TURN THEM AROUND OUT OF THE EAST BY MID EVENING.

SOUTHEAST CA AND SOUTHWEST AZ...INCLUDING KIPL AND KBLH...
MAINLY LOOKING AT BLOWOFF HIGH CLOUDS ACROSS SE CA. CHANCES OF
PRECIP AT BOTH SITES IS SLIM...ONLY GOING TO MENTION SCT-BKN250.
WINDS WILL FAVOR TYPICAL DIURNAL PATTERNS THROUGH SATURDAY MORNING.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SUNDAY THROUGH THURSDAY...
A DRYING TREND WILL KEEP STORM CHANCES MAINLY CONFINED TO THE HIGHER
TERRAIN NORTH AND EAST OF PHOENIX SUNDAY AND MONDAY. MINIMUM
HUMIDITY VALUES IN THE TEENS WILL PERSIST ACROSS THE LOWER DESERTS
FOR SUNDAY AND MONDAY. BY TUESDAY OR WEDNESDAY...AFTERNOON MINIMUM
VALUES WILL IMPROVE...ONLY DROPPING INTO THE 20-30 PERCENT RANGE
WITH ANOTHER INCREASE IN MOISTURE. OVERNIGHT RECOVERY SHOULD BE GOOD
TO EXCELLENT WITH READINGS CLIMBING ABOVE 40 PERCENT MOST NIGHTS.
DAYTIME GUSTY WINDS ARE POSSIBLE EACH DAY...ALONG WITH POSSIBLE
THUNDERSTORM OUTFLOW BOUNDARY WINDS ON SATURDAY AND AGAIN TUESDAY
AND WEDNESDAY.
