The local office's own words before this river 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 river flood warning went out at Jul 27, 2:00 AM MST, 1 hour 11 minutes earlier.

Area forecast discussion, Jul 27, 2:00 AM MST, 1 hour 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
200 AM MST SUN JUL 27 2008

.SYNOPSIS...ENOUGH MOISTURE REMAINS ACROSS THE AREA FOR A CHANCE OF
SHOWERS AND THUNDERSTORMS TODAY. A DRIER WESTERLY FLOW WILL SEE A
DECREASE IN SHOWERS AND THUNDERSTORMS FOR MUCH OF THE WORK WEEK
WHILE ALLOWING HOTTER TEMPERATURES.

&&

.DISCUSSION...SCATTERED SHOWERS AND THUNDERSTORMS CONTINUE IN
EASTERN COCHISE COUNTY WITH DECAYING COMPLEX STRADDLING THE STATE
LINE...OTHERWISE DEBRIS CLOUD ACROSS THE AREA THIS MORNING. AN URBAN
AND SMALL STREAM FLOOD ADVISORY REMAINS IN EFFECT FOR MUCH OF OUR
EASTERN AREAS...AND CURRENTLY WATCHING THE REACTION ON THE GILA
RIVER NEAR DUNCAN. A COUPLE OF WASHES FEEDING JUST UPSTREAM OF THAT
PORTION OF THE RIVER WAS HIT PRETTY HARD EARLIER. REMAINS OF
TROPICAL MOISTURE WRAPPING DEEPER INTO NEW MEXICO WITH THE REMNANT
LOW SHEARING THROUGH NORTHEAST AROUND THE RECEDING HIGH.

THE LAST COUPLE OF SOUNDINGS HAVE TOLD MUCH OF THE TALE AS A
WESTERLY FLOW HAS KICKED IN ALONG WITH MID LEVEL WARMING AND SOME
DRYING. 00Z KTUS SOUNDING HAD PRECIPITABLE WATER DOWN FROM 1.85 TO
1.4. CERTAINLY ENOUGH MOISTURE UNORGANIZED CONVECTION TODAY...BUT
AFTER THAT EXPECT A SIGNIFICANT DECREASE IN THUNDERSTORM COVERAGE
FOR MUCH OF THE WEEK AS A WEST TO SOUTHWESTERLY FLOW ON TOP OF THE
BUCKLING HIGH DRYS THINGS OUT. A MORE FAVORABLE HIGH CENTER
RECONSOLIDATING FURTHER NORTH TOWARD THE END OF THE WEEK SHOULD
BRING THE MOIST FLOW BACK. UNTIL THEN...LESS MOISTURE NOT ONLY MEANS
LESS RAIN...BUT ALSO MORE HEAT.

&&

.AVIATION...ISOLATED SHOWERS AND THUNDERSTORMS EASTERN AREAS THIS
MORNING...OTHERWISE DEBRIS CLOUDS WILL GRADUALLY CLEAR. ANOTHER
CHANCE OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

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