AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 200 AM MST WED AUG 10 2005 .SYNOPSIS...ABUNDANT MOISTURE WILL REMAIN OVER SOUTHEAST ARIZONA THIS WEEK AS AN EAST TO SOUTHEAST FLOW PREVAILS. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO CONTINUE INTO THE WEEKEND. && .DISCUSSION...HIGH PRESSURE CONTINUES OVER THE DESERT SOUTHWEST AND INTERMOUNTAIN REGION EXTENDING INTO THE FRONT RANGE AND SOUTHERN PLAINS. WEAK HIGH CENTER CONSOLIDATED OVER NEW MEXICO HAS BROUGHT A SOUTHERLY COMPONENT TO OUR EASTERLY FLOW OVER THE PAST COUPLE OF DAYS. VERY WET WITH PRECIPITABLE WATER VALUES OVER 1.75 INCHES AND SURFACE DEWPTS IN THE 60S AND 70S. HEAVY SCATTERED COVERAGE TO STORMS HAS GENERALLY MEANT FLOODING PROBLEMS WHEREVER THEY FORM. COMPLEX THROUGH NORTHWEST CHIHUAHUA MAY SEND OUTFLOWS INTO SOUTHEAST PORTIONS THIS MORNING...OTHERWISE EXPECT PARTIAL CLEARING THIS MORNING WITH MORE STORMS FORMING BEFORE NOON. HEAVY RAIN AGAIN THE MAIN CONSIDERATION FOR THIS AFTERNOON AND EVENING. LONG FETCH OF DEEP MOISTURE KEEPS US UNDER THE GUN THROUGH THE WEEK. WEAK IMPULSES IN THE FLOW AND OUTFLOWS WILL CONTINUE TO HELP ORGANIZE CONVECTION THROUGH THE WEEKEND AT LEAST. EVEN IF WE DO START TO PULL IN A WESTERLY FLOW AS THE RIDGE BUCKLES AND SHIFTS OFF EARLY NEXT WEEK...IT WILL TAKE QUITE A WHILE TO DRY OUT (ESPECIALLY CONSIDERING UPSTREAM IN A WESTERLY FLOW WILL INITIALLY BE WET TOO). && .AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && WEATHER.GOV/TUCSON
HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE TUCSON AZ 1155 AM MST TUE AUG 9 2005 AZZ019-029>035-101800- NORTHERN GREENLEE COUNTY-SOUTHEAST PINAL COUNTY- UPPER GILA RIVER VALLEY-WESTERN PIMA COUNTY-TOHONO OODHAM NATION- TUCSON METRO/MARANA/GREEN VALLEY-SANTA CRUZ COUNTY-COCHISE COUNTY- 1155 AM MST TUE AUG 9 2005 THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ARIZONA. .DAY ONE...TODAY AND TONIGHT SYNOPSIS...THUNDERSTORMS ALREADY DEVELOPING MAINLY OVER THE HIGHER TERRAIN LATE THIS MORNING...ESPECIALLY OVER THE CATALINAS AND THE RINCONS...BUT MORE STORMS ARE DEVELOPING IN THE VALLEYS TODAY COMPARED TO YESTERDAY. STORMS ARE DRIFTING SLOWLY TO THE NORTHWEST AND ACTIVITY WILL CONTINUE TO SHIFT TO THE VALLEYS AND FAR WESTERN DESERTS BY THE LATE AFTERNOON AND EARLY EVENING. THE MAIN THREAT WILL BE LOCALIZED FLASH FLOODING...ESPECIALLY ACROSS PIMA COUNTY... SOUTHEAST PINAL...AND COCHISE COUNTIES WHERE SATURATED SOILS WILL CAUSE ADDITIONAL RAINFALL TO RAPIDLY RUNOFF INTO WASHES ALREADY OCCUPIED BY PONDED OR RUNNING WATER. DISCUSSION...THE LATEST PRECIPITABLE WATER IMAGERY INDICATED DEEP MOISTURE OVER MUCH OF THE REGION WITH VALUES FROM 1.6-1.8 INCHES. IN ADDITION DEWPOINT TEMPERATURES AT THE SURFACE ARE GENERALLY IN THE 60S TO LOWER 70S. AN AREA OF DIFFLUENT FLOW REMAINS ACROSS SOUTH CENTRAL ARIZONA BETWEEN THE UPPER HIGH OVER WESTERN NEW MEXICO AND AN INVERTED TROUGH JUST WEST OF THE GULF OF CALIFORNIA INTO SOUTHERN CALIFORNIA. THE REMNANTS OF A STORM COMPLEX FROM THE OVERNIGHT HOURS OVER SONORA MEXICO IS CURRENTLY MAKING ITS WAY TOWARD SOUTH CENTRAL ARIZONA WHICH WILL LIKELY ENHANCE THE ACTIVITY THAT DEVELOPS TODAY... ESPECIALLY OVER CENTRAL AND EASTERN PORTIONS OF PIMA COUNTY. THE 12Z SOUNDING FROM KTUS INDICATED A VERY MOIST AIRMASS IN PLACE WITH A PRECIPITABLE WATER VALUE OF 1.79 INCHES. IN ADDITION...THE AIRMASS WAS VERY UNSTABLE. MID LEVEL WINDS WERE ALSO LIGHT... THEREFORE THE STORMS THAT DEVELOP TODAY SHOULD BE RATHER SLOW MOVERS AND THE THREAT FOR FLOODING RAINS WILL BE THE MAIN THREAT FOR THIS AFTERNOON AND EVENING...BUT WE CANT RULE OUT THE POTENTIAL FOR A FEW OF THE STORMS TO PRODUCE WET MICROBURSTS AS WELL. ONE LIMITING FACTOR FOR THE DEVELOPMENT OF STORMS TODAY WILL BE THE EXTENSIVE CLOUD COVER WHICH WILL LIMIT THE AMOUNT OF SOLAR INSOLATION WE RECEIVE. SLOW NORTHWEST MOVEMENT OF ACTIVITY WILL PROVIDE A HEIGHTENED CONCERN FOR FLASH FLOODING ACROSS MUCH OF THE FORECAST AREA THIS AFTERNOON AND EVENING AS THE SOILS ARE WELL SATURATED FROM HEAVY RAINFALL THE PAST COUPLE OF DAYS IN MANY AREAS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY 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... WEATHER SPOTTERS ARE ENCOURAGED TO REPORT SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES. MOLLERE
