AZZ020>028-CAZ030>033-070600- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 245 PM MST THU SEP 6 2007 .SYNOPSIS... MOISTURE FROM THE REMNANTS OF TROPICAL DEPRESSION HENRIETTE WILL CONTINUE TO MOVE NORTHEASTWARD THROUGH ARIZONA AND NEW MEXICO. THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE SOUTHWEST AND SOUTH-CENTRAL ARIZONA DESERTS...AS WELL AS THE HIGHER TERRAIN OF SOUTHERN GILA COUNTY THROUGH THE EVENING HOURS. HIGH PRESSURE WILL BUILD OVER THE AREA FRIDAY THROUGH THE WEEKEND FOR DRIER AND WARMER CONDITIONS. THE DAILY THREAT FOR SHOWERS AND THUNDERSTORMS WILL BE LIMITED TO THE HIGHER TERRAIN OF NORTHERN AND EASTERN ARIZONA NEXT WEEK...WITH WARM AND DRY WEATHER OVER THE DESERTS. && .SHORT TERM... TONIGHT THROUGH SUNDAY... SAT IMAGERY THIS AFTERNOON CONTINUES TO SHOW CLOUD SHIELD ASSOCIATED WITH THE REMNANTS OF TD HENRIETTE PUSHING NORTHEASTWARD THROUGH SRN ARIZONA AND INTO NEW MEXICO. LATEST RADAR TRENDS SHOW AN AREA OF SCATTERED SHOWERS AND THUNDERSTORMS NORTH OF OUR CWA...BEGINNING TO DRIFT SOUTHWARD INTO FAR NORTHERN MARICOPA COUNTY. THERE ARE ALSO ISOLATED THUNDERSTORMS OVER SOUTHERN GILA COUNTY...AND LA PAZ COUNTY. THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE EARLY EVENING HOURS OVER LA PAZ/YUMA COUNTIES EASTWARD. AFTER MIDNIGHT...A SLIGHT CHANCE WILL CONTINUE FROM CNTRL MARICOPA COUNTY EASTWARD. BY FRIDAY...MODELS SUPPORT A DRYING TREND...WITH LOW LEVEL 700 MB MOISTURE DECREASING FROM 6-7 DEG C THIS EVENING TO ABOUT 1-2 DEG C BY 12/18 UTC FRIDAY. MEANWHILE...MID LEVEL WEAK ANTICYCLONE DEVELOPS OVER THE STATE FOR WARMING TEMPS AND SUBSIDENCE OVER THE AREA. LEFT A SLIGHT CHANCE IN FOR ZONES 23/27 EASTWARD FRIDAY EARLY EVENING. BY THE WEEKEND...WE SHOULD BE HIGH AND DRY...WITH THE THREAT FOR SHOWERS AND THUNDERSTORMS CONFINED TO THE HIGHER TERRAIN OF SOUTHERN GILA COUNTY. TEMPS WILL WARM TO A FEW DEG ABOVE EARLY SEPT AVERAGE...EVEN WARMER OVER THE SE CAL DESERTS AND ALONG THE CO RIVER VALLEY. OVERALL...THESE TRENDS WERE HANDLED WELL IN THE INHERITED FORECAST PACKAGE...AND ONLY MINOR ADJUSTMENTS WERE MADE TO ACCOUNT FOR CURRENT SAT/RADAR/OB TRENDS. PREVIOUS DISCUSSION FROM 1000 MST... RADAR ACROSS SOUTH-CENTRAL ARIZONA IS RELATIVELY QUIET AS THE REMNANTS OF TD HENRIETTE CONTINUE TO SHEAR APART AS SHE DRIFTS NORTHEASTWARD INTO NEW MEXICO TODAY. STRONG MOISTURE GRADIENT IN PLACE FROM SRN NV TO SE AZ. THE 1200 UTC KDRA SOUNDING (DESERT ROCK) HAS AN 850 MB TD OF -14C WHILE KTUS (TUCSON) HAD A 1200 UTC 850 MB TD OF 13 DEG C. THE DRIER AIR TO THE NORTH/NORTHWEST IS DUE TO THE UPPER TROF MOVING THROUGH THE ROCKIES TODAY. THE QUESTION IS HOW QUICKLY WILL THE DRY AIR TO NORTHWEST MOVE INTO THE SOUTH-CENTRAL DESERTS? BOTH THE GFS AND NAM 12 UTC RUNS FROM THIS MORNING HAVE 700 MB TD INCREASING LATER THIS AFTERNOON AS THE MOISTURE FROM THE SE MOVES OVER THE VALLEY FLOORS. BOTH MODELS HOLD ON TO 700 MB TD OF 6-7 DEG C THROUGH 06 UTC TONIGHT (11PM). FCST SOUNDINGS FROM BOTH MODELS ALSO SHOW QUITE A BIT OF INSTABILITY OVER NIGHT FOR THE SOUTH-CENTRAL DESERTS...IN ADDITION TO SOME WEAK UVV AT 700 MB OVER THE AREA. CURRENT FORECAST PRETTY MUCH CONFINES ANY THREAT FOR OVERNIGHT SHOWERS/THUNDERSTORMS TO ZONE 24 SOUTHERN GILA. AT THIS TIME...NOT QUITE SURE THINGS WILL BE COMPLETELY OVER FOR OUR CNTRL AND ERN CWA BY 0600 UTC. WILL DISCUSS WITH OTHER FORECASTERS ON STATION...AS WELL AS BLAST UP CALL WITH NEIGHBORING OFFICES...AND ACCESS THE POSSIBILITY OF EXTENDING THE ZONE 24 SLIGHT CHANCE POPS A BIT FURTHER WEST OVER THE VALLEY FLOORS FROM 06-12 UTC. AFTER 12 UTC...BOTH MODELS AGREE DRIER AIR WILL MOVE INTO CENTRAL AZ...WITH THE CHANCE FOR SHOWERS/TSTMS CONFINED TO THE HIGHER TERRAIN EAST OF PHOENIX. THERE MAY BE ENOUGH RESIDUAL MOISTURE OVER THE AZ CNTRL DESERTS TO WARRANT SLIGHT CHANCE POPS FRI AFT/EVE. BY THE WEEKEND...WELL START A WARM UP WITH CONTINUED DRY CONDITIONS AND NO THREAT FOR SHOWERS/THUNDERSTORMS FROM SE CA TO S-CNTRL AZ DESERTS. IN THE MEANTIME...THE FCST FOR TODAY (SLIGHT CHANCES FROM LA PAZ/YUMA COUNTIES THROUGH MARICOPA COUNTY...INCREASING TO CHANCE POPS OVER THE FAR ERN CWA) SEEMS REASONABLE GIVEN THE CURRENT SITUATION. NO IMMEDIATE CHANGES NEEDED TO THE FORECAST...AS THINGS APPEAR TO BE ON TRACK FOR NOW. && .LONG TERM... SUNDAY NIGHT THROUGH THURSDAY... RIDGE CONTINUES TO STRENGTHEN WITH A NW-SE ORIENTATION. THIS WILL LEAD TO ADDITIONAL DRYING AND WARMING THROUGHOUT THE EXTENDED PERIOD. DIURNAL TSTMS SHOULD DIMINISH AS RIDGE BUILDS IN. KEEPING POPS VERY LOW AND MOSTLY OVER ESTRN MTS WITH TEMPS A LITTLE ABV CLIMO. && .AVIATION... SEPTEMBER 6 1745 UTC (SEPTEMBER 6 1045 MST) KPHX/KIWA ON WRN EDGE OF CLOUD SHIELD ASSOCIATED WITH DECAYING/WEAKING TROPICAL SYSTEM. TAIL END OF A MID LEVEL TROUGH IS MOVING ACROSS NRN AZ...WHICH HAS HELPED TOUCH OF TSTMS ALREADY THIS MORNING OVER THE NRN AZ MTNS. KPHX/KIWA WILL BE IN BETWEEN THESE SYSTEMS. SLIGHT CHANCE /20-30 PERCENT/ THAT TSTMS COULD IMPACT THE AIRFIELDS...BUT THINKING IS THAT MUCH OF THE ACTIVITY WILL BE NORTH AND SE OF THE METRO AREA. TSTMS OVR NRN AZ SHOULD MOVE OFF TO THE EAST...NOT TOWARD PHX...WHILE ACTIVITY TO THE SOUTH WILL LIKELY BE INHIBITED BY CLOUD COVER. WILL USE CBS FOR NOW AND MONITOR FOR UPDATES. WINDS WILL SLOWLY TURN FROM SE TO SW THROUGH THE AFTN. WESTERN TAF SITES...KYUM/KBLH/KIPL...WILL REMAIN DRY WITH MOSTLY SUNNY/CLEAR SKIES AND LIGHT WINDS THROUGH FRIDAY MORNING. SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL FOR MORE DETAILED INFORMATION. AVIATION DISCUSSION IS NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... SEPTEMBER 6 2045 UTC (SEPTEMBER 6 1345 MST) SATURDAY THROUGH THURSDAY...HIGH PRESSURE WILL BUILD BACK OVER THE REGION STARTING THIS WEEKEND...AND WILL REMAIN THROUGH THE COMING WEEK. THIS WILL RESULT IN DRIER AIR SPREADING ACROSS THE REGION. TEMPERATURES IN TURN WILL BEGIN TO INCREASE TO SLIGHTLY ABOVE NORMAL...WHILE RH VALUES DECREASE THROUGH THE PERIOD. RAINFALL CHANCES WILL BE CONFINED TO THE HIGHER TERRAIN OF SOUTHERN GILA COUNTY...WITH NO CHANCES ACROSS THE REST OF THE FORECAST AREA. WINDS WILL REMAIN LIGHT THROUGH THE PERIOD. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE.
