AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
1230 PM MST SUN MAR 29 2009

.UPDATE...
UPDATED AVIATION SECTION.

&&

.SYNOPSIS...
A SERIES OF DRY COLD FRONTS ARE FORECAST TO MOVE THROUGH THE AREA
THE NEXT SEVEN DAYS...PRODUCING BREEZY TO WINDY CONDITIONS AT
TIMES...ALONG WITH NEAR OR SLIGHTLY BELOW NORMAL TEMPERATURES. ONE
DRY COLD FRONT WILL APPROACH THE AREA TODAY...CAUSING GUSTY
AFTERNOON AND EVENING WEST WINDS. ANOTHER DRY COLD FRONT IS EXPECTED
WEDNESDAY...WITH A MORE POWERFUL FRONT LATE FRIDAY. OTHERWISE...
DRY WEATHER IS EXPECTED AREA WIDE THIS WEEK.

&&

.DISCUSSION...
CIRRUS SHIELD THAT HAS FORMED OVER THE PHX CWA PAST 12 HOURS IS
BEING ENHANCED BY 130KT JET CORE DEVELOPING OVER SRN UT. 12Z RH
PROGS INDICATE THIS CLOUDINESS WILL BE WITH US THROUGHOUT THE DAY
BEFORE BEING PUSHED SEWD AWAY FROM CWA THIS EVENING. MEANWHILE...
THE STORY OF THE DAY WILL BE WINDS...WHICH ARE EXPECTED TO INCREASE
DURING THE AFTERNOON HOURS AND CONTINUE INTO THE EVENING AHEAD OF
NEXT DRY COLD FRONT. FRONT WILL NOT ACTUALLY PASS THROUGH THE CWA
UNTIL LATE TONIGHT/EARLY MONDAY MORNING...SO DE-COUPLING IS MUCH
LESS LIKELY TO OCCUR WITH THIS SYSTEM AS WITH THE LAST. SO...WE
SHOULD SEE SOME PRETTY MILD TEMPS TONIGHT. NOT EXPECTING WIND SPEEDS
TO GET OUT OF HAND WITH THIS SYSTEM...MAINLY STAYING UNDER WIND
ADVISORY THRESHOLDS. HOWEVER...WITH LOW HUMIDITIES AND SUFFICIENT
WINDS...FIRE WEATHER CONCERNS ARE STILL AT A HEIGHTENED STATE...
ESPECIALLY ALONG THE LOWER COLORADO AND IN THE HIGHER TERRAIN OF
ZONE 24. AS A RESULT...A RED FLAG WARNING IS STILL IN EFFECT FOR
THOSE AREAS LATE TODAY INTO THIS EVENING. PLEASE REFER TO AWIPS
PRODUCT PHXRFWPSR...WMO ID WWUS85 KPSR FOR THE LATEST DETAILS.
ANOTHER BREEZY TO WINDY DAY MONDAY DOWN THE RIVER BEHIND THE FRONT.
ROLLER-COASTER RIDE WITH TEMPS WILL CONTINUE UFN...WITH MONDAY BEING
QUITE A BIT COOLER THAN TODAY...WARMING TUESDAY AND THEN COOLING
BACK BY THE END OF THE WEEK. SEE PREVIOUS DISCUSSION BELOW FOR END-
OF-THE-WEEK WEATHER DETAILS. NO UPDATES.

PREVIOUS DISCUSSION...
A SERIES OF PACIFIC SHORTWAVE TROFS (3 TO BE SPECIFIC) ARE SCHEDULED
TO ACROSS THE FORECAST AREA (SOUTHEAST CA...AND SOUTHWEST AND SOUTH
CENTRAL AZ) THE NEXT 7 DAYS.  THIS FAR SOUTH ACROSS THE FORECAST
AREA...THE COLD FRONTS WILL BE DRY...BUT PACKING BREEZY TO WINDY
CONDITIONS. ONE SHORTWAVE IS EXPECTED TO MOVE INTO NORTHEAST AZ
TONIGHT...AND WILL DEVELOP GUSTY WEST TO SOUTHWEST WINDS THIS
AFTERNOON AND EVENING (IN THE 15 TO 25 MPH WITH GUSTS TO 30 MPH
RANGE).  GUSTY WINDS WILL BE SHORT OF WIND ADVISORY CRITERIA...
HOWEVER LOW RELATIVE HUMIDITIES HAVE PROMPTED THE ISSUANCE OF A RED
FLAG WARNING TODAY ALONG THE COLORADO RIVER VALLEY...AND OVER THE
COMPLEX TERRAIN OF SOUTHERN GILA COUNTY.

MONDAY AND TUESDAY...
DRY AND COOLER TEMPERATURES ARE EXPECTED AFTER THE FRONTAL PASSAGE.
LINGERING NORTH TO NORTHWEST BREEZES IN THE 10 TO 20 MPH RANGE ARE
ALSO FORECAST FOR MONDAY AFTERNOON.

WEDNESDAY AND THURSDAY...
ANOTHER SHORTWAVE TROF WILL PASS TO THE NORTH OF THE FORECAST AREA.
A DRY TRAILING END COLD FRONT WILL SWEEP ACROSS THE AREA WITH
AFTERNOON BREEZES IN THE 10 TO 20 MPH RANGE WEDNESDAY. MOSTLY CLEAR
SKIES AND LIGHT WINDS ARE EXPECTED THURSDAY.

FRIDAY AND SATURDAY...
A MORE POWERFUL PACIFIC SHORTWAVE IS FORECAST TO PLUNGE INTO ARIZONA
FRIDAY EVENING.  ALL MEDIUM RANGE MODELS HAVE DIFFERENT TIMING AND
INTENSITY SOLUTIONS...HOWEVER THE MEAN OF THESE SOLUTIONS ALL POINT
TO A STRONG LOW PRESSURE SYSTEM IN AZ SOMETIME FRIDAY NIGHT.

ACCORDINGLY WE HAVE INTRODUCED A SLIGHT CHANCE OF SHOWERS OVER THE
MOUNTAINS OF SOUTHERN GILA COUNTY FOR FRIDAY AFTERNOON THROUGH
SATURDAY MORNING. IT APPEARS THIS SYSTEM WILL COME THROUGH
RELATIVELY DRY...HOWEVER THERE MAY BE ENOUGH MOISTURE FOR A SLIGHT
CHANCE OF UPSLOPE MOUNTAIN SHOWERS IN SOUTHERN GILA COUNTY.

THE MOST SIGNIFICANT WEATHER WILL BE WIND...POWERFUL WIND. A STRONG
DRY COLD FRONT WILL HAVE THE POTENTIAL TO DEVELOP GUSTS TO 45 MPH
ALONG THE COLORADO RIVER VALLEY...WITH GUSTS TO 40 MPH ELSEWHERE
FRIDAY EVENING.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX AND KIWA...A DRY COLD FRONT
OVER SOUTHERN NEVADA AND UTAH AT 19Z WILL CONTINUE TO MOVE
SOUTHWARD. SOUTH-SOUTHEASTERLY SURFACE WINDS OF 10-12 KNOTS WILL
SLOWLY BECOME SOUTHWESTERLY BY 21Z WITH INCREASING SPEEDS AS THE
AFTERNOON PROGRESSES. ANTICIPATE SUSTAINED WINDS OF 15-20 KNOTS AND
GUSTS OF 25 KNOTS BY 00Z. ANTICIPATE AREAS OF SUSPENDED DUST THOUGH
VISIBILITIES SHOULD REMAIN ABOVE 6SM...BUT MAY NOT BE MUCH ABOVE
10SM BETWEEN 23Z-01Z. AS THE FRONT GETS CLOSER...ANTICIPATE WIND
DIRECTIONS SLOWLY TURNING TOWARD THE SOUTH-SOUTHEAST AFTER 03Z.
EXPECT LOW LEVEL WIND SHEAR TO BECOME AN ISSUE BETWEEN 08Z-15Z
MONDAY DUE TO STRONG SOUTHWESTERLY FLOW JUST ABOVE THE SURFACE AND
SOUTH-SOUTHEASTERLY SURFACE WINDS. THE FRONT IS NOT EXPECTED TO PUSH
VIGOROUSLY ACROSS SOUTH-CENTRAL ARIZONA BUT WILL WEAKEN AND SLOWLY
MOVE ACROSS THE AREA MONDAY MORNING WITH LIGHT WINDS BECOMING MORE
DISTINCTLY WEST IN THE AFTERNOON. EXCEPT FOR CIRRUS THE REST OF THE
AFTERNOON...CLOUDS WILL BE SCANTY WITH PERHAPS SOME SCATTERED
CUMULUS AT 8-10 KFT ASL AFTER 09Z MONDAY.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KBLH AND
KIPL...SOUTH-SOUTHWESTERLY WINDS OF 15-20 KNOTS WITH GUSTS OF 25-30
KNOTS WILL EXPAND IN AREA THE REST OF THE AFTERNOON AND CONTINUE
UNTIL ABOUT 03Z AHEAD OF A DRY COLD FRONT OVER THE SOUTHERN GREAT
BASIN AT 19Z. SOME AREAS OF BLOWING DUST MAY REDUCE VISIBILITIES
BELOW 10SM AT TIMES BUT WILL GENERALLY REMAIN ABOVE 6SM. THE FRONT
WILL BEGIN TO PUSH SOUTHWARD ACROSS THE AREA AFTER 08Z. BEHIND THE
FRONT...NORTHERLY WINDS OF 20-25 KNOTS WITH GUSTS OF 30-35 KNOTS CAN
BE EXPECTED ALONG THE LOWER COLORADO RIVER VALLEY...A BIT LESS
ELSEWHERE ESPECIALLY THE IMPERIAL VALLEY. SOME LOCALIZED BLOWING
DUST WILL ACCOMPANY THE STRONGEST WINDS THOUGH VISIBILITIES ARE
ANTICIPATED TO REMAIN AOA 5SM. IN AREAS WHERE SURFACE WINDS ARE
LIGHT AND VARIABLE AFTER 08Z BEFORE THE FRONT PASSES THROUGH...LOW
LEVEL WIND SHEAR CAN BE ANTICIPATED. OTHERWISE...EXPECT THE ONLY
CLOUDINESS WILL BE DECREASING CIRRUS.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
...FIRE WEATHER WATCH FOR THE LOWER COLORADO RIVER VALLEY MONDAY...

VERY DRY ANTECEDENT CONDITIONS...COMBINED WITH STRONG GUSTY WINDS
MAY DEMAND THAT THE FIRE WEATHER WATCH BE ELEVATED TO A RED FLAG
WARNING BY FUTURE SHIFTS...WITH THE WATCH EXPANDED TO INCLUDE THE
WEST CENTRAL DESERTS OF ARIZONA IN LA PAZ COUNTY. WINDS WILL BEGIN
TO WEAKEN MONDAY AFTERNOON ACROSS THE AREA. HOWEVER...LOCAL BREEZES
GENERALLY LESS THAN 15 MPH WILL PERSIST OVER THE RIVER ZONES AND THE
SOUTHWEST ARIZONA DESERTS INTO TUESDAY MORNING.

VERY DRY CONDITIONS AND LITTLE CHANGE IN RECOVERY THROUGH THE MIDDLE
OF THE WEEK. BREEZY TO LOCALLY WINDY CONDITIONS WILL OCCUR ONCE
AGAIN AREA-WIDE WEDNESDAY AND THURSDAY AFTERNOON. A STRONGER AREA OF
LOW PRESSURE WILL AFFECT THE AREA FRIDAY AND SATURDAY. THIS SYSTEM
HAS THE POTENTIAL TO BRING SOME MODEST INCREASE IN MOISTURE TO THE
HIGHER TERRAIN OF SOUTHERN GILA COUNTY...BUT THE MAIN THREAT WILL BE
STRONG GUSTY WINDS...UP TO 40 MPH...ACROSS THE DESERTS FRIDAY
AFTERNOON AND EVENING.
