The radar

The Tucson radar (KEMX), 37 km from the middle of the area, began a volume at 06:53 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

Tuscon, AZ (KTUS), launched 00:00Z, 6.9 hours before the alert went out and 5 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.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tucson, AZ wrote its last area forecast discussion before this flash flood warning went out at Jul 19, 8:45 PM MST, 3 hours 6 minutes earlier.

Area forecast discussion, Jul 19, 8:45 PM MST, 3 hours 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
845 PM MST MON JUL 19 2010

.SYNOPSIS...AMPLE MOISTURE AND FAVORABLE EAST TO SOUTHEAST FLOW WILL
BRING AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS TO SOUTHEAST
ARIZONA.

&&

.DISCUSSION...AN EXTREMELY BUSY AFTERNOON AND EVENING FOR THE
EAST/SOUTHEAST CWA...BUT IT APPEARS YET AGAIN THE MAJORITY OF THE
TUCSON METRO AREA WILL BE ON THE SHORT END OF THE RAIN STICK YET
AGAIN. NUMEROUS THUNDERSTORMS ROTATING AROUND UPPER HIGH...STATIONED
OVER CENTRAL ARIZONA...WITH SUBSIDENCE BENEATH THIS HIGH APPARENTLY
PROTECTING MUCH OF THE LOWER DESERTS FROM THUNDERSTORMS.
MEANWHILE...SEVERAL SEVERE THUNDERSTORMS AND FLASH FLOODS REPORTED
ACROSS ESPECIALLY COCHISE COUNTY...WITH HIGHLIGHTS INCLUDING
VEHICLES STRANDED IN FLOODED WASHES NEAR DRAGOON...AND A
THUNDERSTORM OUTFLOW WIND GUST OF 68 MPH AT KDUG...SEE LSR/S ISSUED
DURING THE PAST SEVERAL HOURS FOR DETAILS. TREMENDOUS AMOUNTS OF
RAIN HAVE FALLEN ACROSS MUCH OF COCHISE COUNTY...WITH RAIN
CONTINUING AND EVEN MORE ARRIVING FROM NEW MEXICO. FLASH FLOOD
WARNINGS WERE JUST ALLOWED TO EXPIRE...BUT JUST ISSUED A SMALL
STREAM FLOOD ADVISORY FOR THIS AREA TO COVER CONTINUED RUNOFF. A
LONE THUNDERSTORM FORMED ON OUTFLOW BOUNDARIES NEAR THREE
POINTS...PRODUCING SMALL HAIL AND GUSTY WINDS. WITH THAT LONE
EXCEPTION...CONVECTION HAS BEEN HITTING A BRICK WALL ALONG THE
COCHISE/PIMA COUNTY LINE VICINITY SO FAR...AND WEAKENS AS IT
APPROACHES TUCSON AND THE PROTECTION OF THE RIDGE...EASILY SEEN ON
RADAR MOSAIC LOOPS. GIVEN CURRENT RADAR AS OF 845 PM...IT APPEARS
VERY UNLIKELY THAT COCHISE COUNTY CONVECTION WILL AFFECT EASTERN
PIMA COUNTY IN ANY SIGNIFICANT FASHION. STILL...PLENTY OF MOISTURE
RESIDES OVER THE AREA...AND WITH NUMEROUS OUTFLOWS HANGING
AROUND...RETAINED DECENT POPS FOR MOST AREAS THROUGH 06Z....THEN
TAPERED THEM OFF AFTERWARDS. STRONGEST COMPLEXES OVER THE NEW MEXICO
BOOTHEEL AND SONORA/CHIHUAHUA WILL LIKELY REMAIN THERE FOR THE
REMAINDER OF THE NIGHT...AWAY FROM THE MORE HOSTILE ENVIRONMENT
CLOSER TO THE UPPER HIGH. STILL...SOME SHOWERS/STORMS AROUND TUCSON
FOR SEVERAL MORE HOURS.

00Z NAM RUN TONIGHT FOLLOWS PREVIOUS FORECAST THINKING...WITH UPPER
HIGH SHIFTING EASTWARD TO CENTRAL NEW MEXICO BY TUESDAY AFTERNOON.
00Z NAM STRONGLY SUGGESTS THAT ACTIVITY WILL FAVOR AGAIN THE EASTERN
CWA...GREENLEE/GRAHAM/COCHISE COUNTIES...TUESDAY AFTERNOON. ANY
CAPE/INSTABILITY OF SIGNIFICANCE PROGGED FOR THESE AREAS TOMORROW
AFTERNOON. HOWEVER...THIS AREA WILL BE WELL WORKED OVER FROM
TONIGHT'S CONVECTION...SO WILL WAIT AND SEE IF REALITY MATCHES UP
WITH WHAT NAM SAYS. CLEARLY...ANY MORE HEAVY RAINFALL IN COCHISE
COUNTY WILL POSE PROBLEMS TOMORROW ON SATURATED SOILS/ELEVATED
STREAMS AND WASHES.

&&

.AVIATION...SCT TSRA/SHRA GRADUALLY DIMINISHING THROUGH 06-09Z.
CLOUD BASES AROUND 3-6K FT AGL WITH REDUCED VSBYS VICINITY STRONGER
TSTMS. STRONG GUSTY AND ERRATIC OUTFLOW WINDS FROM SOME STORMS.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...AMPLE MOISTURE AND FAVORABLE EAST TO SOUTHEAST FLOW
WILL BRING AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS TO
SOUTHEAST ARIZONA THIS WEEK.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...NONE.

1030 AM MST MON JUL 19 2010

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ARIZONA AND SOUTHEAST ARIZONA.

.DAY ONE...TODAY AND TONIGHT

ALTHOUGH A MOIST ATMOSPHERE REMAINS IN PLACE ACROSS SOUTHEAST ARIZONA
TODAY...THE MID TO UPPER-LEVEL HIGH CENTER TEMPORARILY TRACKS OVER
THE AREA BEFORE TAKING UP RESIDENCE OVER NORTHERN NEW MEXICO
TOMORROW. THIS WILL MAKE THE ATMOSPHERE SLIGHTLY MORE STABLE ALOFT
TODAY. ALTHOUGH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL
BE POSSIBLE THIS AFTERNOON AND EVENING...COVERAGE WILL BE DOWN FROM
THAT EXPERIENCED OVER THE PAST FEW DAYS.

HOWEVER...STORMS WILL STILL BE CAPABLE OF PRODUCING DAMAGING WIND
GUSTS AND LOCALIZED HEAVY RAINFALL. RAINFALL AMOUNTS NEAR THE
STRONGEST STORMS WILL APPROACH ONE INCH...WHICH CAN PRODUCE
LOCALIZED FLOODING PROBLEMS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

ISOLATED TO SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS WILL RESULT IN A THREAT OF STRONG THUNDERSTORM OUTFLOW
WINDS AND LOCALIZED HEAVY RAINFALL. EXPECT AN ELEVATED CHANCE OF
THUNDERSTORMS DURING THE SECOND HALF OF THE WORK-WEEK...AS THE UPPER
FLOW PATTERN BECOMES FAVORABLE FOR CONVECTIVE DEVELOPMENT.

.SPOTTER INFORMATION STATEMENT...

WEATHER SPOTTERS ARE ENCOURAGED TO REPORT SIGNIFICANT WEATHER
CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES.
