AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
200 PM MST WED MAR 25 2009

.SYNOPSIS...
AN UPPER LEVEL DISTURBANCE AND ASSOCIATED COLD FRONT WILL PUSH
ACROSS THE AREA DURING THE AFTERNOON AND EVENING ON THURSDAY. THIS
WILL GIVE AN INCREASE IN WIND DURING THE DAY...WHICH MAY RESULT IN
BLOWING DUST IN THE DESERTS. THE SYSTEM IS A DRY ONE WITH NO RAIN
EXPECTED. HIGHER PRESSURE WILL THEN RETURN TO THE AREA FOR FRIDAY
AND SATURDAY FOR WARMER AND SUNNY WEATHER. ANOTHER DRY WEATHER
SYSTEM WILL PUSH THROUGH EARLY NEXT WEEK FOR MORE BREEZY CONDITIONS.

&&

.DISCUSSION...
STRONG SHORTWAVE TROUGH SYSTEM PUSHING SEWD TODAY DOWN THE FRONT
SIDE OF HIGH-AMPLITUDE ERN PAC RIDGE. THIS TROUGH...DUE TO ITS
OVERLAND TRAJECTORY...WILL CONTAIN LITTLE IN THE WAY OF MOISTURE AS
IT PASSES THRU THE PHX CWA ON THURSDAY. SO...POPS HAVE BEEN REDUCED
TO LESS THAN 10 PCNT. FRONTAL PASSAGE THRU THE ENTIRE CWA WILL BE
SOMETIME BETWEEN 19Z AND 01Z TOMORROW.

GFS REMAINS STRONGER WITH IT/S WIND FIELDS AS COMPARED TO THE NAM.
PREFER THE GFS SOLUTION AS A GREAT DEAL OF THE OTHER AVAILABLE MODEL
GUIDANCE /SREF AND ECMWF/ BETTER SUPPORT IT. BY 00Z FRI THE GFS
DEVELOPS A 35+ KT H85 NW JET ACROSS LA PAZ/MARICOPA/PINAL COUNTIES.
MODEL SOUNDINGS SUGGEST AN AVERAGE BOUNDARY LAYER WIND IN THE
PHOENIX AREA OF 25-30 MPH WITH GUSTS OVER 40 MPH. THEREFORE...HAVE
DECIDED TO HOIST A WIND ADVISORY FOR BASICALLY THE ENTIRE CWA EXCEPT
FOR FAR SW AZ/FAR SE CA ZONES FOR 19Z THU-02Z FRI. BREEZY CONDITIONS
WILL CONTINUE INTO FRIDAY MORNING AS A SECOND STRONG NLY LLJ
DEVELOPS ALONG THE LOWER COLORADO RIVER VALLEY. GIVEN THE DRY AND
COOL AIRMASS MOVING IN...EXPECT MOST AREAS TO DECOUPLE WITH THE
EXCEPTION OF SE CA/SW AZ MOUNTAINS SUCH AS THE CHOCOLATE AND KOFA
MOUNTAINS.

PLENTY OF DRY SOIL CONDITIONS TO BE AFFECTED BY WINDS...SO WILL
CONTINUE THE MENTION OF BLOWING DUST/SAND IN WX GRIDS. COLD FRONT
WILL PASS THRU LATE ENOUGH THAT WE SHOULD STILL SEE SOME DECENT
WARMING...WITH WARMEST DESERTS NEAR 80 DEG F TOMORROW. IN THE WAKE
OF THE UPPER TROUGH...TEMPS WILL LOWER ABOUT 5 TO 8 DEGREES ON
FRIDAY...WITH MUCH LESS WIND.

PREVIOUS DISCUSSION...
SATURDAY THROUGH MID NEXT WEEK...A DRY NORTHWEST FLOW WILL CONTINUE
...WITH MODELS POINTING TOWARD ANOTHER WEATHER SYSTEM TO BRUSH BY TO
THE NORTHEAST SUN/MON. THIS NEXT SYSTEM IS EXPECTED TO UNFOLD
SIMILARLY TO THE SHORT TERM SYSTEM...WITH THE MAIN IMPACT ONCE AGAIN
WINDY WEATHER AND DRY CONDITIONS. TEMPS WILL GRADUALLY WARM TO
WITHIN A FEW DEG OF NEAR NORMAL FOR LATE MARCH...UPPER 70S TO LOW 80
ACROSS THE WARMEST DESERT LOCALES.

&&

.AVIATION...
WESTERLY WINDS WILL DEVELOP FOR ALL TAF SITES THIS AFTERNOON AS THE
MOUNTAIN/VALLEY CIRCULATION SETS UP. FROM 02-06Z WINDS WILL SWITCH
TO A DRAINAGE FLOW. THURSDAY MORNING THE DRAINAGE WINDS WILL
PERSIST...BUT FROM 16Z-19Z STRONG W/NW WINDS WILL DEVELOP AS A LOW
PRESSURE SYSTEM MOVES IN FROM THE NW. WINDS WILL BE STRONGEST
/GENERALLY SUSTAINED 20-30KT WITH GUSTS 35-40 KTS/ AT KPHX AND
NEARBY SITES AND THE KBLH AREA. WEAKER...BUT STILL WINDY...
CONDITIONS CAN BE EXPECTED AT KIPL AND KYUM. BLDU WILL ALSO BE
POSSIBLE.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...

...RED FLAG WARNING IN EFFECT FROM NOON MST /NOON PDT/ TO 7 PM MST
/7 PM PDT/ THURSDAY FOR THE LOWER COLORADO RIVER VALLEY...THE
SOUTHWEST AND SOUTH-CENTRAL ARIZONA DESERTS...AND SOUTHERN GILA
COUNTY FOR STRONG WINDS...LOW RH VALUES...AND A HIGH FIRE DANGER...

STRONG WINDS WILL QUICKLY INCREASE THURSDAY AS A POWERFUL LOW
PRESSURE SYSTEM MOVES THROUGH THE FOUR CORNERS REGION. HAVE OPTED TO
CONVERT THE FIRE WEATHER WATCH TO A RED FLAG WARNING AS CONFIDENCE
IS HIGH ON CRITICAL THRESHOLDS BEING MET. AFTER DISCUSSION WITH THE
SOUTHERN CALIFORNIA GACC...DECIDED TO HOLD OFF ON ISSUING A HEADLINE
PRODUCT THERE DUE TO FUEL MOISTURE LEVELS BEING A BIT DAMP. HOWEVER
...WINDS AND RH VALUES IN THOSE AREAS WILL REMAIN A CONCERN. SEE
PHXRFWPSR...WWUS85 KPSR...FOR ADDITIONAL DETAILS.

FRIDAY THROUGH SUNDAY...
A STRONG LOW PRESSURE SYSTEM LOCATED OVER EASTERN NEW MEXICO WILL
CONTINUE TO MOVE EASTWARD...LEAVING THE REGION IN A DRY NORTHWEST
FLOW ALOFT. BREEZY CONDITIONS CAN BE EXPECTED FRIDAY AFTERNOON ALONG
THE LOWER COLORADO RIVER VALLEY INTO SOUTHEAST CALIFORNIA...WITH
GUSTS TO AROUND 30 MPH POSSIBLE. A WEAK RIDGE OF HIGH PRESSURE WILL
BUILD OVER THE REGION SATURDAY...LEADING TO SLIGHTLY ABOVE NORMAL

FALL WELL BELOW 15 PERCENT EACH DAY AS A DRY AIRMASS REMAINS IN
PLACE.
