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 Aug 24, 9:12 PM MST, 16 minutes earlier.

Area forecast discussion, Aug 24, 9:12 PM MST, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
912 PM MST TUE AUG 24 2010

.SYNOPSIS...SHOWERS WITH ISOLATED TO SCATTERED THUNDERSTORMS WILL
DECREASE IN COVERAGE OVERNIGHT TONIGHT.A GRADUAL DECREASE IN SHOWERS
AND THUNDERSTORMS IS EXPECTED WEDNESDAY INTO FRIDAY...FOLLOWED BY
ANOTHER UPSWING IN THUNDERSTORM ACTIVITY BY EARLY NEXT WEEK. ABOVE
NORMAL HIGH TEMPERATURES WILL CONTINUE THIS WEEK.

&&

.DISCUSSION...IT WAS A WIDESPREAD ACTIVE AFTERNOON AND EVENING
ACROSS SOUTHEAST ARIZONA TODAY. THE COMBINATION OF A WEAK MID-LEVEL
FLOW AND A SOMEWHAT DRY SUB-CLOUD LAYER RESULTED IN STRONG PULSE
TYPE STORMS INITIALLY...ESPECIALLY FOCUSED ALONG A BACKDOOR FRONT
THAT EXTENDED ACROSS THE AREA. THESE PULSE STORMS RESULTED IN STRONG
OUTFLOWS THAT NOT ONLY COLLIDED WITH OTHER THUNDERSTORM
OUTFLOWS...BUT THE FRONTAL BOUNDARY EXTENDING ALONG THE CENTRAL
PORTIONS OF THE FORECAST AREA AS WELL. TO MAKE THINGS EVEN MORE
ACTIVE...A VORT MAX ROTATING AROUND THE MID-LEVEL HIGH OVER SOUTHERN
NEVADA ALLOWED FOR STORMS TO MOVE FROM THE RIM TO THE SSW INTO THIS
ALREADY ACTIVE AREA. IN ANY EVENT...THERE WAS STILL SIGNIFICANT
COVERAGE OF SHOWERS WITH MODERATE TO HEAVY RAINFALL ALONG WITH
ISOLATED TO SCATTERED THUNDERSTORMS AS OF 9 PM MST. EXPECT COVERAGE
TO RAPIDLY DECREASE OVER THE NEXT FEW HOURS. UPDATED THE FCST TO FIT
THIS SCENARIO. HOWEVER...AND MCS LOOKS LIKE IT IS BEGINNING TO
DEVELOP OVER NORTH CENTRAL SONORA MEXICO...JUST TO THE SOUTH OF THE
HUACHUCA MOUNTAINS. RUNOFF FROM THIS FEATURE MAY BE PROBLEMATIC TO
THE SAN PEDRO RIVER BASIN INTO TOMORROW MORNING.

OTHERWISE...THERE ARE STILL PLENTY OF RUNOFF ISSUES ACROSS THE
FORECAST AREA LATE THIS EVENING...WITH THE MOST SIGNIFICANT RAINFALL
OCCURRING NEAR SAFFORD WHERE GAGES REPORTED OVER 3 INCHES OF RAIN
HAS FALLEN OVER MOUNT GRAHAM AND LOCATIONS JUST SOUTH OF THE TOWN
ITSELF. STREAM GAGES NOT REPORTING ANY MAJOR FLOODING PROBLEMS AS OF
9 PM MST...BUT SIGNIFICANT RUNNING WATER IS STILL ANTICIPATED IN
SOME LOCALES THROUGH THE EARLY MORNING HOURS DUE TO THE OVERALL
COVERAGE OF PCPN.

&&

.AVIATION...NUMEROUS SHOWERS WITH ISOLATED TO SCATTERED -TSRA WITH
CLOUD BASES 5-7KFT WILL PERSIST ACROSS SOUTHEAST ARIZONA TO THE EAST
OF A KOLS-KTUS-KSAD LINE THROUGH MIDNIGHT. THESE STORMS WILL
DECREASE IN COVERAGE THROUGH DAYBREAK. EXPECT ELY/SELY SURFACE WINDS
AT 10-15 KTS WITH SOME GUSTS TO AROUND 20 KTS. AVIATION DISCUSSION
NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...NO FIRE WEATHER CONCERNS AT THIS TIME.

&&

.PREV DISCUSSION...SOMEWHAT LESS THUNDERSTORM ACTIVITY...EXCEPT FOR
THE WESTERN DESERTS...WAS EXPECTED WEDNESDAY AND THURSDAY.
THEREAFTER...AN INCREASE IN SHOWERS AND THUNDERSTORMS CAN BE
ANTICIPATED FRIDAY AND SATURDAY AS A TROUGH OF LOW PRESSURE
INTERACTS WITH MOISTURE OVER THE AREA. GFS MODEL WAS RATHER
CONSISTENT IN ADVECTING DRIER AIR INTO MUCH OF ARIZONA SUNDAY INTO
EARLY NEXT WEEK. THIS SHOULD RESULT IN A SIGNIFICANT DECREASE IN
THUNDERSTORM ACTIVITY SUNDAY INTO WEDNESDAY OF NEXT WEEK. ABOVE
NORMAL HIGH TEMPERATURES CAN BE EXPECTED THROUGH FRIDAY...THEN
DAYTIME READINGS WILL TREND CLOSER TO NORMAL OR A FEW DEGS BELOW
NORMAL BY EARLY NEXT WEEK.

&&

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

SMALL HAIL.

THUNDERSTORMS THIS AFTERNOON HAVE DEVELOPED FARTHER WEST THAN

SOUTHEAST PINAL AND PIMA INTO WESTERN SANTA CRUZ COUNTIES AS OF 1

THUNDERSTORMS AND THE FACT THAT THE STEERING FLOW ALOFT REMAINED
LIGHT...THUNDERSTORMS SHOULD BE FAVORED ACROSS THE LOWER DESERTS OF
PIMA AND PINAL COUNTIES THE REMAINDER OF THIS AFTERNOON AND EARLY
THIS EVENING.

THUNDERSTORMS DEVELOPING ACROSS GREENLEE...GRAHAM...AND COCHISE
COUNTIES SHOULD REMAIN MORE ISOLATED IN NATURE FOR MUCH OF THIS
AFTERNOON. THUNDERSTORMS MAY INCREASE IN COVERAGE THIS EVENING
ACROSS MAINLY COCHISE COUNTY AS A WEAK DISTURBANCE OVER MEXICO
PASSES BY THE REGION.

STORM MOVEMENT THIS AFTERNOON AND EVENING WILL BE TOWARD THE WEST
AT LESS THAN 10 MPH.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

THERE WILL BE A CHANCE OF SHOWERS AND THUNDERSTORMS MAINLY IN
