AREA FORECAST DISCUSSION...CORRECTED WWA SECTION
NATIONAL WEATHER SERVICE PHOENIX AZ
835 PM MST THU OCT 9 2008

SOUTH-CENTRAL AND SOUTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA
FORECAST DISCUSSION

.SYNOPSIS...
A SIGNIFICANT COOLING TREND IS IN STORE FOR OUR REGION THIS WEEKEND
AS A STRONG LOW PRESSURE SYSTEM MOVES THROUGH. WINDS WILL BEGIN TO
INCREASE TODAY...WITH BREEZY CONDITIONS IN THE AFTERNOON...BECOMING
BREEZY TO WINDY FOR FRIDAY AND SATURDAY. THE STRONGEST WINDS WILL
OCCUR ACROSS THE MOUNTAINS EAST OF PHOENIX ON SATURDAY WHERE THERE
WILL ALSO BE INCREASED CHANCES FOR PRECIPITATION. HIGH TEMPERATURES
WILL BE COOLEST ON SATURDAY WITH MOST AREAS IN THE 60S AND 70S. LOWS
SUNDAY MORNING WILL BE IN THE 40S AND 50S. A WEAK HIGH PRESSURE
SYSTEM WILL BEGIN TO BUILD IN ON SUNDAY AND REMAIN THROUGH THE WEEK
RESULTING IN QUIET AND SLOWLY WARMING WEATHER.

&&

.DISCUSSION...
CLEAR SKIES WERE NOTED ACROSS THE FORECAST AREA (SOUTHEAST CA TO
SOUTH CENTRAL AZ) THIS EVENING. NO WEATHER PROBLEMS FORESEEN THROUGH
FRIDAY MORNING.

OTHERWISE...A LARGE COLD LOW PRESSURE SYSTEM CONTINUED TO DEVELOP
OVER THE PACIFIC NORTHWEST THIS EVENING. THIS SYSTEM IS STILL
EXPECTED TO PLUNGE SOUTH INTO SOUTHWEST NEVADA BY LATE FRIDAY NIGHT.
MODELS FORECAST VERY STRONG 500 MB HEIGHT FALLS...150 METER 12 HR
FALLS OVER FAR NORTHWEST AZ BY 12Z SAT...WITH 110 METER FALLS OVER
NORTH CENTRAL AZ BY 18Z SAT.  HEIGHT FALLS OF THIS MAGNITUDE PORTEND
STRONG VERTICAL MOTION/COLD ADVECTION RESULTING IN VERY WINDY
CONDITIONS. WIND GUSTS COULD PEAK TO NEAR 40 MPH IN SOUTHEAST CA AND
THE COLORADO RIVER VALLEY LATE FRIDAY NIGHT...SPREADING WEST INTO
SOUTH CENTRAL AZ (INCLUDING PHOENIX) BY SATURDAY MORNING.  A WIND
ADVISORY IS CURRENTLY POSTED SATURDAY FOR THE MOUNTAIN AND MOUNTAIN
VALLEYS OF SOUTHERN GILA COUNTY (ZONE 24) WHERE GUSTS TO 50 ARE
POSSIBLE.

ONE QUESTION IS...WILL THERE BE ANY RAINFALL IN SOUTH CENTRAL AZ
(PHOENIX EASTWARD) WITH THE COLD FRONT.  CURRENT HURRICANE
NORBERT...370 MILES SOUTHWEST OF THE BAJA TIP AT 03Z...HAD SLOWLY
SPREAD TROPICAL MOISTURE INTO NORTHWEST MEXICO THE PAST FEW DAYS.
00Z FRI TUCSON BALLOON SOUNDING SHOWED A SLIGHT INCREASE IN LOW
LEVEL MOISTURE...BUT NOT SIGNIFICANT YET. ON THE OTHER HAND... THE
HERMOSILLO BASED GPS PRECIP WATER (PW) SOUNDER HAS SHOWN A
FLAT-LINING OF PW THE PAST 24 HOURS...AROUND 1.10 INCHES. THIS IN
CONTRAST TO THE TUCSON SOUNDING PW OF 0.68 INCHES THIS EVENING.

MODELS SHOW THAT STRONG 500 MB HEIGHT FALLS OVER NORTHWEST AZ LATE
FRI NIGHT/SAT MORNING WILL PROMOTE INCREASING AGEOSTROPHIC 850/700
MB WINDS...CALCULATED FROM THE SOUTHEAST AT 10 TO 15 KNOTS.
THEREFORE...NORTHWEST MEXICO MOISTURE COULD FLOW INTO THE COLD
FRONT...TOWARD SOUTH CENTRAL AZ FOR A BRIEF 2 TO 4 HOUR PERIOD
SATURDAY MORNING. A SLIGHT CHANCE OF SHOWERS WILL CONTINUE SATURDAY
FROM PHOENIX EASTWARD.

OTHERWISE CURRENT FORECASTS LOOK OK. NO UPDATES PLANNED.  PREVIOUS
DISCUSSION BELOW STILL APPLIES.

PREVIOUS DISCUSSION...
FRIDAY NIGHT A STRONG COLD FRONT WILL ENTER THE NW CORNER OF OUR CWA
AND PUSH ACROSS MOST OUR CWA BY 18Z SAT. STRONG WINDS WILL DEVELOP
AHEAD OF THE SYSTEM WITH THE NAM/GFS INDICATING A 70KT H7 JET. WILL
ISSUE A WINDY ADVISORY FOR SRN GILA COUNTY FROM 8AM THROUGH 5PM SAT.
BEST AREA/TIME FOR PRECIP WILL BE ACROSS SRN GILA COUNTY SAT MORNING
AS MOISTURE FLUX PEAKS DUE TO SLIGHT BACKING OF THE STRONG SLY FLOW
ALLOWING SOME MOISTURE TO BE PULLED WESTWARD. BY SAT AFTERNOON CF
WILL BE PUSHING THE MOISTURE PLUME EAST AND WILL BEGIN TO TAPER DOWN
POPS. NOT EXPECTING TO SEE MUCH IF ANY PRECIP ACROSS PHX...WITH THE
EAST VALLEY MORE LIKELY TO SEE ANY SHOWERS. MUCH DRIER AIR WILL
SPREAD IN BEHIND THE FRONT DURING THE AFTERNOON HOURS SAT WITH NO
PRECIP FOR EL CENTRO/YUMA AREAS. CONDITIONS FOR A RED FLAG WARNING
ARE CURRENTLY BORDERLINE AND WILL THEREFORE HOLD OFF ON ISSUING ANY
HEADLINE FIRE WX PRODUCTS.

SIGNIFICANTLY COOLER TEMPS EXPECTED SATURDAY AS THE TIMING OF THE
CF PASSAGE WILL STRONGLY INHIBIT TYPICAL DIURNAL WARMING. BROUGHT
MAX TEMPS DOWN A FEW DEGREES...INTO THE MID 60S TO MID 70S...FROM
PREVIOUS FORECAST AND THIS MAY STILL BE GENEROUS. BY SUNDAY MORNING
COLD AIRMASS SETTLES IN AND WINDS SHARPLY WEAKEN. WITH A CLEAR SKY
EXPECTED CONDITIONS WILL BE FAVORABLE FOR STRONG RADIATIONAL COOLING
RESULTING IN LOWS IN THE 40S AND 50S.

NOT A BIG CHANGE IN TEMPERATURES FROM SAT TO SUN AS AIRMASS WILL BE
SLOW TO RECOVER. SOME MODEST WARMING THEN TAKES PLACE THROUGH THE
REMAINDER OF THE WEEK AS HEIGHTS SLOWLY INCREASE. MODELS INDICATING
THAT SOME RESIDUAL ENERGY/WEAK TROUGHING WILL REMAIN OVER THE REGION
THROUGH THE WEEK. WILL HOLD ON TO A DRY FORECAST FOR NOW BUT WE MAY
EVENTUALLY SEE SOME SHOWERS OVER ERN AZ LATER IN THE WEEK.

&&

.AVIATION...
SOUTHEAST CA AND THE COLORADO RIVER VALLEY...INCLUDING KIPL...KNYL
AND KBLH...

CLEAR SKIES AND LIGHT SOUTHWEST WIND UNDER 12 KNOTS IS EXPECTED
THROUGH 16Z FRI.  HOWEVER...A STRONG SOUTHWARD MOVING COLD
FRONT...NEAR LAS VEGAS BY 18Z FRI...WILL RESULT IN GUSTY SOUTHWEST
SURFACE WINDS IN THE 15 TO 25 KNOT RANGE BETWEEN 16Z FRI AND 03Z SAT.
MOSTLY CLEAR SKIES ARE ALSO EXPECTED THROUGH FRIDAY EVENING.

SOUTH CENTRAL AZ INCLUDING KPHX AND KIWA AIRFIELDS...
CLEAR SKIES AND LIGHT WIND (UNDER 10 KNOTS) ARE EXPECTED THROUGH 16Z
FRI. HOWEVER...AN APPROACHING DRY COLD FRONT WILL PRODUCE 24 KNOT
SOUTHWEST WINDS IN THE 1 TO 2 THOUSAND FOOT LAYER...WITH THE
POSSIBILITY OF LOW LEVEL WIND SHEAR FROM 11Z TO 16Z FRI AT KPHX AND
KIWA AIRPORTS. AFTER 16Z FRI...INCREASING SURFACE WINDS 10 TO 20
KNOTS...AND GUSTY...WILL DEVELOP THROUGH 02Z SAT. MOSTLY CLEAR SKIES
ARE ALSO FORECAST THIS PERIOD.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SATURDAY THROUGH MONDAY...
DEEP UPPER LOW PRESSURE SYSTEM WILL GIVE WINDY WEATHER TO ALL FIRE
WX ZONES ON SATURDAY...AND THERE WILL BE A SLIGHT CHANCE OF SHOWERS
OVER SCNTRL AZ FRIDAY EVENING THROUGH SATURDAY...ESPECIALLY HIGHER
TERRAIN. MEANWHILE...WITH DRIER AIR WRAPPING INTO THE REGION FROM
THE SW BY SATURDAY...HUMIDITIES AND WINDS COULD REACH CRITICAL
THRESHOLDS FOR A FEW HOURS SATURDAY AFTN/EARLY EVENING...MAINLY OVER
SCNTRL AZ DESERTS. LATER SHIFTS WILL NEED TO ASSESS THE POSSIBLE NEED
FOR A FIRE WEATHER WATCH THIS AREA. LESS WIND EXPECTED ON SUNDAY AS
THE UPPER LOW GRADUALLY WEAKENS...BUT STILL COULD SEE SOME GUSTS
NEAR 25 MPH. BY MONDAY...GENERALLY CLEAR SKIES AND MUCH LESS WIND
WILL BE THE RULE ACROSS THE AREA UNDER HIGHER PRESSURE ALOFT.
