NWS Tucson, AZ wrote its last area forecast discussion before the first event at Aug 4, 2:40 PM MST, 4 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 240 PM MST THU AUG 4 2005 .SYNOPSIS...HIGH PRESSURE WILL EXTEND FROM THE FOUR CORNERS TO THE GREAT BASIN...KEEPING THE DESERT SOUTHWEST IN A MONSOONAL FLOW PATTERN. THERE WILL BE DAY TO DAY VARIATIONS...BUT IN GENERAL... MOISTURE WILL REMAIN SUFFICIENT FOR MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THROUGH EARLY NEXT WEEK. && .DISCUSSION...STANDARD MONSOON CONVECTIVE DAY IN PROGRESS ACROSS THE FORECAST AREA. MORNING CLOUD COVER HAS BEEN SLOW TO BURN OFF WHICH HAS MADE FOR A SLOW START TO CONVECTION ACROSS ERN CWA...BUT LATEST PSR RADAR IMAGERY SHOWS STRONG STORMS FORMING OVER ERN MOUNTAINS. TSTMS ALREADY MORE NUMEROUS VERSUS YESTERDAY ACROSS THE AREA...MCV CURRENTLY ACROSS WRN CWA WITH CONVECTION FIRING NEAR ORGAN PIPE. MODEST INCREASE IN FLOW PUSHING INTO ERN AREAS...WITH 15-25 KT OF EASTERLY MID LEVEL FLOW NOTED FLOWING BELOW FOUR CORNERS HIGH. AGAIN THE MAIN CONCERN WILL BE FLASH FLOODING...DUE TO RELATIVELY SLOW STORM MOVEMENT...WITH ELEVATED CONCERNS OVER SANTA CRUZ AND ESPECIALLY WESTERN AND CENTRAL PIMA COUNTY WHERE HEAVY RAINS HAVE OCCURED THE PAST FEW DAYS. OTHERWISE...HAVE NOT MADE ANY DRASTIC CHANGES TO PREVIOUS FORECAST...WITH STANDARD MONSOON CONDITIONS EXPECTED THROUGH THE FORECAST PERIOD. FLOW WILL LIKELY TURN MORE NORTHEASTERLY HEADING INTO THE WEEKEND...AS THE FOUR CORNERS HIGH SHIFTS A BIT WEST TO NEAR LAS VEGAS. THIS WILL BE FAVORABLE FOR STORMS TO FORM OVER THE MOGOLLON RIM AND PROPAGATE SOUTHEAST INTO THE LOWER DESERTS BY LATE AFTERNOON. SO WE WILL KEEP SCATTERED TSTM CHANCES THROUGH THE WEEKEND. NOTICE TO USERS... KEMX WSR-88D IS INOPERATIVE. RETURN TO SERVICE AS OF THIS WRITING IS NOT EXPECTED UNTIL SOMETIME TODAY...MOST LIKELY IN THE LATE AFTERNOON OR EVENING. && .AVIATION...ISOLATED/SCATTERED THUNDERSTORMS AT OR IN THE VCNTY OF TERMINALS CAN BE EXPECTED WITH SFC WND G35KT AND REDUCED VSBYS TO 4SM POSSIBLE IN TSRA UNTIL 06Z. && .TWC WATCHES/WARNINGS/ADVISORIES...FLOOD WARNING FOR SMALL STREAMS IN EFFECT TODAY FOR CENTRAL PIMA COUNTY.(VAMORI WASH) && PUBLIC...SHOEMAKER AVIATION...SHOEMAKER WEATHER.GOV/TUCSON
HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE TUCSON AZ 955 AM MST THU AUG 4 2005 AZZ019-029>031-033>035-051400- NORTHERN GREENLEE COUNTY-SOUTHEAST PINAL COUNTY- UPPER GILA RIVER VALLEY-WESTERN PIMA COUNTY- TUCSON METRO/MARANA/GREEN VALLEY-SANTA CRUZ COUNTY-COCHISE COUNTY- 955 AM MST THU AUG 4 2005 THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ARIZONA. .DAY ONE...TODAY AND TONIGHT SYNOPSIS...SCATTERED SHOWERS AND THUNDERSTORMS WILL FIRST DEVELOP OVER THE HIGHER TERRAIN...ESPECIALLY ALONG A LINE FROM DOUGLAS TO SAFFORD AROUND NOON. THESE STORMS WILL THEN MOVE WEST AT 10 TO 15 MPH INTO THE VALLEYS BY MID AFTERNOON. THESE STORMS WILL THEN BEGIN TO SLOW DOWN TO 5 TO 10 MPH AS THEY PUSH INTO THE LOWER DESERTS OF SOUTHWEST ARIZONA BY LATE AFTERNOON AND EARLY EVENING. THESE STORMS WILL INITIALLY HAVE THE ABILITY TO ORGANIZE INTO CLUSTERS INCREASING THE THREAT OF DAMAGING THUNDERSTORM WINDS. THE MOIST ATMOSPHERE ACROSS SOUTHEAST ARIZONA WILL ALLOW THE THREAT FOR LOCALIZED FLASH FLOODING TO CONTINUE TODAY...ESPECIALLY ACROSS THE CENTRAL AND WESTERN PORTIONS OF PIMA COUNTY WHERE STORMS WILL MOVE SLOWER AND RAIN WILL FALL ON ALREADY SATURATED SOILS. DISCUSSION...AN UPPER HIGH CENTERED OVER THE CENTRAL PLAINS TODAY WILL ALLOW AN EASTERLY FLOW TO SETUP ACROSS SOUTHEAST ARIZONA. THIS FLOW HAS IMPORTED DRIER AIR INTO THE FAR EASTERN PORTIONS OF THE STATE...AND HAS DEVELOPED A LOW AND MID LEVEL MOISTURE BOUNDARY ROUGHLY SETUP ALONG A LINE FROM DOUGLAS TO SAFFORD. THIS BOUNDARY IS CLEARLY EVIDENT ON THE LATEST GOES-10 PRECIPITABLE WATER IMAGERY. IN THE UPPER ATMOSPHERE...A MOISTURE BOUNDARY AS SEEN ON WATER VAPOR WILL CONTINUE TO NUDGE INTO THE SOUTHEAST CORNER OF THE STATE BY THE EARLY AFTERNOON HOURS. THIS BOUNDARY WILL INTERACT WITH THE LOW AND MID LEVEL MOISTURE BOUNDARY TO SERVE AS A FOCUSING MECHANISM TO HELP INITIATE CONVECTION. IN ADDITION...A WEAK AREA OF UPPER DIFFLUENCE WILL SUPPORT STRONG THUNDERSTORM UPDRAFTS ALONG AND AHEAD OF THE UPPER MOISTURE BOUNDARY. ALTHOUGH THE MORNING UPPER AIR SOUNDING FROM TUCSON INDICATED A WEAK SOUTHEAST STEERING FLOW AT 5 MPH...THIS SHOULD CONTINUE TO INCREASE THROUGHOUT THE DAY...BECOMING EAST AROUND 10 TO 15 MPH. THE INCREASE IN SPEED SHEAR WILL ALLOW STORMS TO BECOME MORE ORGANIZED...POSSIBLY FORMING INTO MULTICELLULAR CLUSTERS BY LATE THIS AFTERNOON... AND THUS INCREASING THE RISK OF DAMAGING THUNDERSTORM WINDS. ALTHOUGH THE FASTER STORM MOTION WOULD GENERALLY DECREASE THE THREAT FOR VERY HEAVY DOWNPOURS...THESE STORMS ARE MOVING INTO A VERY MOIST LOWER AND MIDDLE ATMOSPHERE THE FURTHER WEST THEY PUSH. THE GREATEST CONCERN FOR FLASH FLOODING IS ACROSS CENTRAL AND WESTERN PIMA COUNTY LATE THIS AFTERNOON AND EVENING...WHERE THE STEERING FLOW WILL SLOW DOWN THE STORMS OVER AN ALREADY WELL SATURATED AREA. OTHERWISE...LOOK FOR THUNDERSTORMS TO FIRST DEVELOP OVER THE HIGHER TERRAIN...ESPECIALLY NEAR THE MOISTURE BOUNDARIES ROUGHLY ALONG A LINE FROM DOUGLAS TO SAFFORD AROUND NOON. THESE STORMS WILL THEN MOVE WEST AT 10 TO 15 MPH INTO THE VALLEYS BY MID AFTERNOON. THESE STORMS WILL THEN BEGIN TO SLOW DOWN TO 5 TO 10 MPH AS THEY PUSH INTO THE LOWER DESERTS OF SOUTHWEST ARIZONA BY LATE AFTERNOON AND EARLY EVENING. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY THERE WILL BE SCATTERED AFTERNOON AND EVENING THUNDERSTORMS THROUGHOUT THE PERIOD WITH THE POSSIBILITY OF LOCALIZED FLASH FLOODING AND DAMAGING WINDS POSSIBLE. .SPOTTER INFORMATION STATEMENT...
