AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PHOENIX AZ
950 PM MST MON SEP 8 2014

.UPDATED...UPDATED AVIATION DISCUSSION...

&&

.SYNOPSIS...
MOISTURE WILL REMAIN IN PLACE ACROSS THE REGION FOR THE NEXT SEVERAL
DAYS...HOWEVER MOST OF THE LIFT IN THE ATMOSPHERE WILL BECOME
FOCUSED OVER NORTHERN ARIZONA. THUS...ONLY SCATTERED SHOWERS AND
THUNDERSTORMS ARE EXPECTED IN SOME AREAS THROUGH TUESDAY...THOUGH
SOME COULD STILL SEE BRIEF PERIODS OF HEAVY RAIN. A GRADUAL DRYING
TREND WILL BEGIN STARTING DURING THE MIDDLE OF THE WEEK AS HIGH
PRESSURE SLOWLY REBUILDS OVER THE REGION.

&&

.DISCUSSION...
CONVECTION CONTINUES ACROSS FAR WESTERN ARIZONA AND SOUTHEAST
CALIFORNIA THIS EVENING. RADAR AND SATELLITE TRENDS INDICATE A FEW
POP UP SHOWERS ARE EXTENDING SOUTHEASTWARD INTO MARICOPA AND PIMA
COUNTIES ALTHOUGH NOTHING THAT FAR SOUTH HAS BECOME WELL ORGANIZED.
STILL...COULD SEE A FEW SPRINKLES OR SHOWERS ACROSS THE METRO
OVERNIGHT. WILL NUDGE POPS UP SLIGHTLY ACROSS PHOENIX THROUGH
TUESDAY MORNING.

MEANWHILE...00Z NAM AND RAP INDICATE SHOWERS WILL BLOSSOM ACROSS
WESTERN ARIZONA AROUND 12Z OR SOONER AS UPPER FLOW BECOMES MORE
ORGANIZED AND WIND SPEEDS INCREASE. GIVEN FAVORABLE UPSLOPE FOR AND
QUITE A BIT OF MOISTURE STILL IN PLACE ACROSS THE REGION...I AM
GOING TO CONTINUE WITH THE FLASH FLOOD WATCH FOR THE FAVORED UPSLOPE
AREAS NORTH/WEST OF PHOENIX THROUGH TUESDAY EVENING.

&&

.PREVIOUS DISCUSSION...
COMPLICATED FORECAST FOR TUESDAY AS MANY COMPETING FEATURES COME
INTO PLAY DRIVING (OR INHIBITING) CONVECTIVE INITIATION AND
COVERAGE. FORCES/ELEMENTS FAVORABLE FOR CONVECTION INCLUDE A
CONTINUATION OF AN ABNORMALLY MOIST ENVIRONMENT (BOUNDARY LAYER
MIXING RATIOS 11-14 G/KG) AND FORCED ASCENT APPROACHING FROM THE
NORTHWEST IN ASSOCIATION WITH ANOTHER WAVE MOVING TOWARDS NORTHWEST
ARIZONA. DETRIMENTAL FACTORS INCLUDE A VERY DISCERNIBLE DRYSLOT
MOVING NORTH ON THE EASTERN SIDE OF THE OLD NORBERT CIRCULATION WEST
OF THE BAJA...AND WARM AIR ADVECTION IN THE MIDLEVELS HELPING REDUCE
OVERALL INSTABILITY. THE VAST MAJORITY OF HIGH RESOLUTION CONVECTIVE
MODELS (WHICH HAVE PERFORMED VERY WELL IN THIS EVENT TO THIS POINT)
REALLY TARGET NORTHWEST ARIZONA EXTENDING SOUTH INTO LA PAZ AND YUMA
COUNTIES AS THE PRIME REAL ESTATE FOR CONVECTIVE COVERAGE.
THEREFORE...HAVE REALLY TRIMMED POPS OVER THE SERN CWA INCLUDING THE
PHOENIX METRO...WHILE FOCUSING 50 PERCENT CHANCES OVER THE
AFOREMENTIONED AREAS.

FOR WEDNESDAY INTO THE WEEKEND...A SLOW DRYING AND WARMING TREND
WILL COMMENCE AS HIGH PRESSURE ALOFT STEADILY BUILDS ACROSS THE AREA
FROM THE WEST. TOTAL MOISTURE WILL RATHER SLOW TO ERODE AS LOW/MID
LEVEL WIND FIELDS WILL BE ON THE WEAK SIDE...HOWEVER NOTABLE DRY AIR
SEEN IN WV IMAGERY OVER THE EAST PACIFIC SHOULD OVERTAKE MUCH OF THE
AREA. HOWEVER...SOME CONVECTION WILL STILL BE POSSIBLE OVER HIGHER
TERRAIN OF SOUTHERN GILA COUNTY...THOUGH UPPER WINDS WILL MOSTLY
FAVOR THE SOUTHWEST WHICH IS AN UNFAVORABLE DIRECTION FOR BRINGING
ANY HIGHER TERRAIN STORMS INTO THE LOWER DESERTS. EXPECT HIGH
TEMPERATURES TO SLOWLY RISE...REACHING TO AROUND SEASONAL NORMAL
VALUES BY ABOUT FRIDAY.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
STARTING TO SEE SOME ACTIVITY CREEPING INTO THE WEST VALLEY. GOING
TO MENTION VCSH AT ALL TAF SITES OVERNIGHT BUT IT APPEARS THE BEST
AREAS WILL BE IN THE HIGHER TERRAIN TO THE NORTH AWAY FROM THE
TERMINALS. GIVEN THE ABUNDANCE OF MOISTURE IN THE ATMOSPHERE AND
LINGERING BOUNDARIES FROM THIS MONDAY MORNING\S
CONVECTION...CONFIDENCE IN HOW TONIGHT WILL EVOLVE IS LOW. STORMS
SHOULD RE-FIRE TUESDAY AFTERNOON ACROSS THE AREA...VCSH REINTRODUCED
LATE IN THE TAF PERIOD.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
STORMS MORE LIKELY ACROSS AZ THAN SE CA ON TUESDAY BUT I WILL RETAIN
A MENTION OF VCSH AT BLH FOR A FEW HOURS OVERNIGHT...AND AGAIN
DURING THE AFTERNOON. DRIER AIR SHOULD WORK IN FROM THE SOUTHWEST
LATE IN THE TAF PERIOD.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
THURSDAY THROUGH MONDAY.
A GRADUAL DRYING TREND WILL COMMENCE DURING THE MIDDLE OF THE WEEK
AS MOISTURE GETS SCOURED OUT FROM THE NORTHWEST. ANY SHOWER AND
THUNDERSTORM CHANCES WOULD BE VERY SLIGHT...AND PRIMARILY LIMITED TO
THE HIGHER TERRAIN OF GILA COUNTY DURING THE AFTERNOON AND EARLY
EVENING HOURS. AFTERNOON HUMIDITY LEVELS WILL GENERALLY FALL INTO A
15-30 PERCENT RANGE WITH GOOD TO EXCELLENT OVERNIGHT RECOVERY. ASIDE
FROM SOME AFTERNOON UPSLOPE GUSTINESS...WIND SPEEDS WILL REMAIN
RELATIVELY LIGHT.
