AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PHOENIX AZ
1041 AM MST THU OCT 29 2015

.UPDATE...UPDATED AVIATION DISCUSSION...

&&

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL TRACK ACROSS THE SOUTHWEST STATES THROUGH
EARLY SATURDAY. THIS WILL BRING A CHANCE OF SHOWERS TODAY AND FRIDAY
EAST OF THE LOWER COLORADO RIVER VALLEY. WINDY CONDITIONS CAN BE
EXPECTED NEAR AND WEST OF THE LOWER COLORADO RIVER VALLEY LATER
TONIGHT AND DURING THE DAY FRIDAY. COOLER TEMPERATURES ARE IN STORE
REGION-WIDE. CLEARING SKIES ARE FORECAST SATURDAY...WITH A RETURN TO
NEAR NORMAL TEMPERATURES SUNDAY AND MONDAY. ANOTHER WEATHER SYSTEM
AFFECTS THE REGION TUESDAY AND WEDNESDAY.

&&

.DISCUSSION...
A STRONG NEGATIVE TILT WAVE WAS DIVING INTO THE SWRN CONUS THIS
MORNING WITH LARGE SCALE SYNOPTIC ASCENT GENERALLY OVERSPREADING THE
REGION. WV IMAGERY DEPICTS A COMPACT SHORTWAVE DESCENDING SOUTHEAST
INTO FAR NORTHWEST ARIZONA...WHILE AN OBJECTIVELY ANALYZED MERIDIONAL
60+KT H5 JET STREAK THROUGH CALIFORNIA SUGGESTS FURTHER DEEPENING OF
THE LONGWAVE TROUGH AND ENCAPSULATED VORTICITY CENTER. DESPITE
OVERALL MINIMAL AVAILABLE INSTABILITY...ROBUST COLD ADVECTION ALOFT
WAS FUELING SCT SHOWERS AND EMBEDDED THUNDERSTORMS NEAR THE COLORADO
RIVER VALLEY WHILE CLEARING WAS TAKING PLACE THROUGH CENTRAL AND
SOUTHWEST ARIZONA.

CONCEPTUALLY AND WITH SUPPORT OF SEVERAL HIGH RESOLUTION
MODELS...THE COMBINATION OF SFC HEATING...APPROACHING COLD ADVECTION
ALOFT...POCKETS OF MIDLEVEL FRONTOGENETICAL FORCING...AND VORTICITY
ADVECTION WILL SUPPORT FURTHER DEVELOPMENT OF SCT SHOWERS THROUGH
CENTRAL ARIZONA LATER THIS AFTERNOON. THERE WILL CERTAINLY BE A
WINDOW FOR THUNDERSTORMS LATE AFTERNOON WITH FAVORABLE LAPSE RATES
AND ASCENT...BEFORE DRY AIR AND LOSS OF DAYTIME HEATING DECREASES
THE OVERALL THREAT. HAVE MADE SOME LARGER ADJUSTMENTS TO CLOUD COVER
THIS MORNING BASED ON SATELLITE TRENDS...WHILE REFINING
PRECIPITATION CHANCES TOWARDS SHORT TERM TRENDS AND ENSEMBLE OUTPUT.

&&

.PREVIOUS DISCUSSION...
/355 AM MST THU OCT 29 2015/
TODAY AND FRIDAY...
THE LOW IS EXPECTED TO DEEPEN OVER THE STATE IN THE NEXT 24-36
HOURS...SAGGING ACROSS NORTHERN MEXICO...THE AXIS GRADUALLY SHIFTING
EAST AND TAKING ON MORE OF A POSITIVE TILT WITH TIME. WITH THIS
MOVEMENT...PRECIPITATION CHANCES/MODEL QPF KEEP SCATTERED SHOWERS
AND THUNDERSTORMS CONTINUING ACROSS SOUTH-CENTRAL ARIZONA THROUGHOUT
THE DAY TODAY INTO FRIDAY...PRECIPITATION CHANCES TRENDING DOWNWARD
BY FRIDAY AFTERNOON AS THE LOW MOVES EAST AND MORE STABLE CONDITIONS
TAKE HOLD. COOLER DAYTIME TEMPERATURES ON TAP TODAY AND FRIDAY...
WITH SOME OF THE LOWER DESERT ELEVATIONS DIPPING INTO THE 70S.

ON THE BACK SIDE OF THE TROUGH...STRONGER LOW LEVEL WINDS ARE
EXPECTED TO DEVELOP ACROSS SOUTHEAST CALIFORNIA AND SOUTHWEST
ARIZONA AS NORTHERLY 40-50KT 850MB WINDS MATERIALIZE LATER THIS
EVENING INTO FRIDAY MORNING. THE MOMENTUM OF THE STRONG WINDS WILL
PERIODICALLY MAKE IT TO THE SURFACE...SO ADVISORY STRENGTH WINDS ARE
POSSIBLE NEAR AND WEST OF THE LOWER COLORADO RIVER VALLEY THURSDAY
NIGHT AND FRIDAY. ANTICIPATE THE STRONG WINDS TO PRODUCE SOME
LOCALIZED BLOWING DUST/SAND IN THIS AREA.

SATURDAY THROUGH MONDAY...THE PACIFIC TROUGH OVER ARIZONA IS
FORECAST TO MOVE EAST INTO NEW MEXICO AND WEST TEXAS EARLY SATURDAY
FOR MOSTLY SUNNY AND CLEAR SKIES OVER OUR FORECAST AREA. RIDGING
OVER THE DESERT SOUTHWEST WILL ALLOW TEMPERATURES TO SLOWLY WARM UP
THROUGH THE WEEKEND...STAYING IN THE LOW TO MID 80S THIS PERIOD.

TUESDAY AND WEDNESDAY...A MORE POTENT UPPER LEVEL LOW IS SLATED TO
DROP SOUTHWARD FROM BRITISH COLUMBIA AND THE PACIFIC NORTHWEST.
CURRENTLY THE ECMWF AND GFS ARE NOW BETTER AGREEMENT IN THE
TRACK/STRENGTH OF THE LOW AS IT DROPS SOUTH OVER THE GREAT
BASIN...THE TRACK FURTHER WEST THAN PREVIOUS RUNS...AND THE
EVOLUTION A BIT SLOWER...SPORTING A 546DM 500MB CLOSED LOW OVER
SOUTHERN NEVADA BY WEDNESDAY MORNING. THE TREND IN THE EXTENDED
FORECAST IS STILL ONE FOR COOLER DAYTIME TEMPERATURES...IN THE LOW
70S FOR THE DESERTS...AND SLIGHT PRECIPITATION CHANCES MAINLY OVER
SOUTH-CENTRAL ARIZONA TUESDAY THROUGH MIDWEEK.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
MORNING SHOWERS HAVE SINCE EXITED TO THE EAST...BUT ADDITIONAL
SHOWERS AND ISOLATED STORMS ARE EXPECTED LATER THIS AFTERNOON.
COVERAGE WILL BE SPOTTY AND PROBABLY NOTHING MORE THAN VCSH BUT ALL
PHOENIX TERMINALS STAND A CHANCE OF A BRIEF SHOWER THROUGH 03Z
TONIGHT. CIGS COULD BRIEFLY LOWER TO AROUND 5-6KFT WITHIN THE
HEAVIEST SHOWERS BUT PREVAILING CIGS WILL BE CLOSER TO 8-10KFT. WINDS
WILL FAVOR TYPICAL DIURNAL PATTERNS THROUGH FRIDAY MORNING.

SOUTHEAST CALIFORNIA/SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
VERY LOW CHANCE OF SHOWERS AT BLH /ALREADY INDICATIONS THAT SHOWERS
ARE MOVING EASY/...THUS I WILL KEEP SE CA TAFS DRY. BIGGER CONCERN
WILL BE GUSTY WINDS ESPECIALLY AT BLH LATE TONIGHT INTO TOMORROW AS
STRONG NORTHERLY WINDS DEVELOP DOWN THE COLORADO RIVER VALLEY. WINDS
WILL BE GUSTY /CLOSE TO 30KTS AT TIMES/ EARLY FRIDAY MORNING BUT
SHOULD GRADUALLY RELAX JUST AFTER THE END OF THE TAF PERIOD. WHILE
WINDS WILL BE GUSTY...THEY WON'T BE NEARLY AS STRONG AT IPL.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SATURDAY THROUGH THURSDAY...
SATURDAY AND SUNDAY...DRY WEATHER WITH NEAR NORMAL TEMPERATURES.
LIGHT WIND. MINIMUM RELATIVE HUMIDITY WILL RANGE FROM 15 PERCENT IN
