TO BE IN THE 30 TO 35 MPH RANGE FOR THE MOST PART. SINCE THIS IS LESS

AREA FORECAST DISCUSSION...CORRECTED WWA SECTION
NATIONAL WEATHER SERVICE PHOENIX AZ
200 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...
LOW LEVEL MOISTURE IS ALREADY INCREASING ACROSS SRN AZ AZ IS EVIDENT
BY INCRG DEW POINTS AND THE DEVELOPMENT OF CU ALONG THE 1-10
CORRIDOR FROM PHX TO TUS. SLY FLOW OF 10-20 KTS...LIKELY ENHANCED
WITH SYNOPTIC FORCING FROM NORBERT...WILL CONTINUE TO INCREASE
MOISTURE LEVELS. OVERALL THE MODELS ARE HANDLING THE CURRENT
SITUATION WELL THOUGH DISCUSSIONS WITH HPC/TPC /THROUGH WFO TWC/
INDICATE THE MODELS MAY NOT BE ADEQUATELY RESOLVING NORBERT/S
CIRCULATION. OTHERWISE MID-LATITUDE WAVE CONTINUES TO DEVELOP AND
DIG OVER THE NW CONUS AS SEVERAL SHORTWAVES MOVE THROUGH IT.

SYSTEM WILL BE MOVING INTO OUR CWA ON FRIDAY RESULTING IN LOWER
TEMPERATURES AND INCREASING CLOUD COVER. TIGHT MOISTURE GRADIENT
WILL BE DEVELOPING OVER OUR CWA...WITH MUCH DRIER AIR OVER OUR WRN
ZONES. NOT EXPECTING TO SEE ANY PRECIP UNTIL POSSIBLY FRIDAY EVENING
ACROSS SRN GILA COUNTY. TEMPERATURES WILL BE SEVERAL DEGREES COOLER
FRIDAY AS COMPARED TO TODAY.

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...
BREEZY CONDITIONS CAN BE EXPECTED TODAY AS SURFACE PRESSURE GRADIENT
TIGHTENS IN RESPONSE TO DEVELOPING LOW PRESSURE IN UTAH. GUSTS OF 15
TO 25 KTS CAN BE EXPECTED AREA-WIDE THIS AFTERNOON. SKIES WILL
REMAIN CLEAR. OVERNIGHT...WINDS WILL REMAIN A BIT STRONGER THAN
NORMAL /GREATER THAN 10 KTS/ WITH TYPICAL DIURNAL PATTERNS STILL
TAKING HOLD. COULD BE SOME LOW-LEVEL WIND SHEAR BETWEEN 10 AND 16Z
FRIDAY IN THE LOWEST 5000 FEET WITH WINDS ABOVE THE SURFACE AROUND
25 KTS...BUT DID NOT INCLUDE IN THE TAFS ATTM. APPROACHING UPPER
LEVEL LOW PRESSURE SYSTEM WILL ENHANCE WESTERLY WINDS TOMORROW WITH
GUSTS OF 20 TO 30 KTS POSSIBLE DURING THE DAY.

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.

&&

.PSR WATCHES/WARNINGS/ADVISORIES...

AZ...WIND ADVISORY FROM 8 AM TO 5 PM MST SATURDAY FOR AZZ024.
