AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PHOENIX AZ
1225 PM MST TUE JUN 3 2008

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

.UPDATE...UPDATED AVIATION DISCUSSION

&&

.SYNOPSIS...
A SERIES OF UPPER LEVEL DISTURBANCES WILL PUSH ACROSS OR JUST TO THE
NORTH OF THE DESERT SOUTHWEST THE NEXT SEVEN DAYS. EACH ONE OF THESE
WILL BE RESPONSIBLE FOR KICKING UP BREEZES...INCLUDING THE SYSTEM
EXPECTED TO MOVE THROUGH ON WEDNESDAY. THIS SYSTEM WILL ALSO HELP TO
LOWER AFTERNOON HIGH TEMPERATURES BY A FEW DEGREES ON THURSDAY.
ANOTHER WARMING TREND WILL BE EVIDENT OVER THE UPCOMING WEEKEND...
BUT ALL-IN-ALL TEMPERATURES WILL ONLY WARM BACK UP CLOSE TO SEASONAL
NORMALS.

&&

.DISCUSSION...
DRY...POSITIVELY-TILTED UPPER LEVEL SHORTWAVE TRAVERSING ACROSS AZ
TODAY WITH LITTLE NOTICEABLE AFFECT ON SENSIBLE WEATHER. TEMPS ARE
OFF A FEW DEGREES COMPARED TO YESTERDAY AT PRESS TIME...BUT SOUNDINGS
WOULD ARGUE THEY SHOULD CATCH UP DURING AFTERNOON HEATING.

NOT MUCH HAS CHANGED REGARDING OUR THINKING WITH THE MUCH STRONGER
SHORTWAVE SCHEDULED TO MOVE ACROSS TO OUR N ON WED/WED NIGHT.
LATEST MOS FROM OUR WRN SITES WOULD ARGUE FOR WIND ADVISORY CO RIVER
WWD LATE WED MORNING INTO WED EVENING. WILL LOOK FURTHER INTO THIS
AS LATER MODEL DATA FILTERS IN AND MAKE ANY CHANGES IN AFTERNOON
PKG. MEANWHILE...BEST COOLING APPEARS AS IF IT WILL HOLD OFF UNTIL
THU...PERHAPS EVEN A FEW DEGREES UNDER WHAT WE ARE CURRENTLY CALLING
FOR. COOLING WILL BE SHORT-LIVED AS MODELS AGREE STRONG WARMING WILL
COMMENCE BY FRIDAY.

NO UPDATES NEEDED TODAY.

PREVIOUS DISCUSSION...
TODAY...ELONGATED SHORT WAVE TROUGH AND ASSOCIATED VORT LOBE WILL
SLIDE EASTWARD ACROSS THE FORECAST AREA TODAY. THE TROUGH WILL BRING
DRIER AIR TO THE REGION ALONG WITH NEGLIGIBLE HEIGHT FALLS. NEUTRAL
TEMPERATURE ADVECTION BELOW 700 MB WILL EQUATE TO HIGH TEMPERATURES
ROUGHLY WHERE THEY WERE MON AFTERNOON...AROUND 101 DEGREES IN
PHOENIX.

WED...GFS HAS CAUGHT UP TO THE ECMWF WITH ITS DEPICTION OF A CLOSED
MID-LEVEL LOW ACROSS THE GREAT BASIN. WED WILL BE THE WINDIEST DAY
OF THE WEEK AS THE LOCAL PRESSURE GRADIENT TIGHTENS IN RESPONSE TO
LEE CYCLOGENESIS TAKING PLACE ACROSS THE CENTRAL PLAINS. LATEST GFS
SUGGESTS MIXING THROUGH ABOUT 750 MB WILL PRODUCE LATE AFTERNOON
WIND GUSTS BETWEEN 25 AND 30 MPH IN THE GREATER PHOENIX AREA.

THU...CYCLONIC FLOW IN THE WAKE OF THE SYSTEM WILL BE STEERED DOWN
THE COLORADO RIVER VALLEY AND ACROSS THE AZ DESERTS...THOUGH WINDS
WILL NOT BE NEARLY AS STRONG AS THOSE ON WED. MEANWHILE...SLIGHTLY
COOLER AIR MASS WILL MOVE IN BEHIND THE LOW...WITH TEMPS FAILING TO
REACH THE HUNDRED DEGREE MARK.

FRI...ANOMALOUSLY HIGH 500 MB HEIGHTS (ASSOCIATED WITH A BUILDING
SUBTROPICAL RIDGE) WILL TRANSLATE TO THE LOWER LEVELS IN THE FORM OF
STRONG WARM ADVECTION. AFTER A BRIEF COOLDOWN THE DAY
BEFORE...TEMPERATURES ARE EXPECTED TO RECOVER QUICKLY...WITH HIGHS
LIKELY REACHING THE HUNDRED DEGREE MARK IN PHOENIX UNDER SUNNY SKIES.

EXTENDED...MODELS IN GENERALLY GOOD AGREEMENT THAT CONDITIONS WILL
REMAIN DRY WITH LITTLE TO NO CHANCE FOR PRECIPITATION. GFS APPEARS
TO BE RELIABLE THROUGH ABOUT SUN-MON...WITH A WARMING TREND
ADVERTISED THROUGH MON. MODELS DIVERGE SIGNIFICANTLY EARLY NEXT
WEEK...THOUGH A SLIGHT COOLDOWN TUE SEEMS LIKE A GOOD BET WITH THE
MAJORITY OF THE GUIDANCE SHOWING AN AREA OF LOW PRESSURE DEVELOPING
ACROSS THE WESTERN CONUS.

&&

.AVIATION...
CLEAR SKIES AND LIGHT WINDS CONTINUE ACROSS ENTIRE AREA AT MID DAY.
LATE AFTERNOON AND EVENING WINDS LIKELY TO PICK UP AND BECOME OCNLY
GUSTY...WITH SOME GUSTS TO BE 20-25 KTS IN THE YUMA/BLYTHE/IMPERIAL
AREA. LOOK FOR BREEZY CONDITIONS WEST OF THE LOWER COLORADO RIVER
VALLEY THIS EVENING AND DURING THE OVERNIGHT HOURS.

STRONGER WINDS...ASSOCIATED WITH UPPER TROUGH AND COLD FRONT WILL
ARRIVE IN SOUTHEAST CALIF FIRST...THEN SPREAD INTO PHOENIX METRO
AREA WEDNESDAY. EXPECT WIND SPEEDS OF 20 TO 30 KTS AHEAD OF THE
FRONT...AND SOME AREAS OF LOWER VISIBILITY IN THE KIPL-KYUM-KBLH
AREA DUE TO BLOWING DUST/SAND ON WEDNESDAY.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
UPSWING IN WINDS ARRIVES TOMORROW AS A LOW PRESSURE SYSTEM MOVES
INTO THE WESTERN STATES. HAVE HELD OFF ON ISSUING A FIRE WEATHER
WATCH BECAUSE IT APPEARS THAT WINDS IN THE ARIZONA AND LOWER
COLORADO RIVER VALLEY ZONES WILL BE JUST SHY OF CRITICAL
THRESHOLDS...ALTHOUGH IT IS POSSIBLE THAT ISOLATED MOUNTAIN TOP
LOCATIONS MAY REACH CRITERIA. WINDS WILL BE STRONGER OVER SOUTHEAST
CALIFORNIA. HOWEVER...THE DURATION OF CRITICAL THRESHOLDS LOOKS LIKE
IT WILL NOT BE QUITE LONG ENOUGH FOR A FIRE WEATHER WATCH. WINDS AT
MOST PLACES WILL PEAK BETWEEN 4-8 PM...THOUGH SOUTHEAST CALIFORNIA
MAY PEAK BETWEEN 5-10 PM. WINDS WILL NOT BE AS STRONG
THURSDAY...THOUGH BREEZY TO LOCALLY WINDY CONDITIONS CAN BE EXPECTED
OVER OVER MAINLY SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA WITH
WINDS FAVORING NORTHWEST AND NORTH DIRECTIONS. LIGHT WINDS ARE
EXPECTED FRIDAY WITH SOMEWHAT STRONGER WINDS OVER THE WEEKEND AND
EARLY NEXT WEEK.

THE LOW PRESSURE SYSTEM WILL BE DRY AND LEAD TO MODEST COOLING
FOLLOWED BY GRADUAL WARMING.
