AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
340 PM MST SAT JUL 2 2011

.SYNOPSIS...
GUSTY WINDS FROM THE SOUTHEAST AND EAST AND BLOWING DUST ARE
EXPECTED IN THE SOUTH-CENTRAL ARIZONA DESERT INCLUDING THE GREATER
PHOENIX AREA BY THIS EVENING. ISOLATED THUNDERSTORMS ARE EXPECTED
BUT WITH LITTLE IF ANY RAIN IN THE DESERT. HUMIDITY WILL INCREASE
WITH AN INCREASING CHANCE OF MOSTLY LATE AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS SUNDAY AND THE 4TH OF JULY. BLOWING DUST
IS EXPECTED IN THE DESERT AREAS AHEAD OF THE THUNDERSTORMS. IT WILL
NOT BE AS HOT BEGINNING SUNDAY. A SLIGHT CHANCE OF MAINLY LATE
AFTERNOON AND EVENING THUNDERSTORMS WILL PERSIST THROUGH THE END OF
THIS COMING WEEK.

&&

.DISCUSSION...
THERE WAS SOME CLOUDINESS FROM THE EAST-SOUTHEAST MOVING ACROSS
SOUTH-CENTRAL AND SOUTHWEST ARIZONA INCLUDING THE GREATER PHOENIX
AREA EARLY THIS AFTERNOON WHILE IT WAS SUNNY OVER SOUTHEAST
CALIFORNIA. DESPITE THE CLOUDINESS...TEMPERATURES WERE GENERALLY 4
TO 6 DEGREES WARMER COMPARED WITH THE SAME TIME YESTERDAY. THERE
WERE ALSO ISOLATED THUNDERSTORMS SOUTH AND EAST OF PHOENIX EASTWARD
ACROSS THE HIGHER TERRAIN WITH ISOLATED REPORTS OF BLOWING DUST IN
THE DESERT AREAS. DEW POINT TEMPERATURES WERE GENERALLY 10 TO 20
DEGREES HIGHER IN SOUTH-CENTRAL ARIZONA WITH LITTLE CHANGE IN
SOUTHEAST CALIFORNIA. WIND WAS GENERALLY LIGHT MOSTLY FROM THE EAST
AND SOUTHEAST...EXCEPT GUSTY NEAR THUNDERSTORMS.

THE HIGH PRESSURE SYSTEM ALOFT OVER NEW MEXICO HAS BECOME STRONGER
WITH THE HOTTEST WEATHER SO FAR THIS YEAR AND RECORD HIGH
TEMPERATURES TODAY. THE HIGH TEMPERATURE OF 118 DEGREES AT PHOENIX
SKY HARBOR AS OF 312 PM MST THIS AFTERNOON IS THE 4TH HIGHEST
TEMPERATURE EVER RECORDED AT SKY HARBOR AND BROKE THE RECROD HIGH
TEMPERATURE FOR THE 2ND OF JULY OF 116 DEGREES SET IN 1990. PRIOR TO
1990...THE 118 DEGREE READING WAS THE ALL-TIME RECORD HIGH FOR
PHOENIX.

THE HIGH PRESSURE SYSTEM WILL BECOME ESTABLISHED NEAR THE 4 CORNERS
AND FILTER SOME MOISTURE INTO OUR AREA BY TONIGHT WITH A MORE
SIGNIFICANT INCREASE IN MOISTURE SUNDAY AND THE 4TH OF JULY.

THUNDERSTORMS THAT DEVELOP TO OUR EAST ARE EXPECTED TO SEND STRONG
GUSTY OUTFLOW WINDS AND BLOWING DUST INTO THE SOUTH-CENTRAL ARIZONA
DESERT AREAS LATE THIS AFTERNOON AND THIS EVENING AND POSSIBLY AS
FAR WEST AS LA PAZ COUNTY AFTER THAT THIS EVENING. THE THUNDERSTORMS
FROM THE HIGHER TERRAIN TO THE EAST THAT MOVE WEST ARE EXPECTED TO
BE ONLY ISOLATED WITH VERY LITTLE IF ANY RAINFALL OVER THE
SOUTH-CENTRAL ARIZONA DESERT AREAS. THE PREVIOUS DISCUSSION STILL
APPLIES.

PREVIOUS DISCUSSION...
A SIGNIFICANT COOL DOWN IS EXPECTED SUNDAY AS BOTH THE GFS AND ECMWF
SHOW DEEPER MOISTURE WORKING ITS WAY NORTHWARD INTO THE SONORAN
DESERT. ALTHOUGH HEAT INDICES ABOVE 105 DEGREES ARE EXPECTED
SUNDAY...LOCAL EXCESSIVE HEAT CRITERIA WILL NOT BE MET AND THE
WARNING WAS TRIMMED BACK IN TIME IN THE FORECAST PACKAGE ISSUED
EARLY THIS MORNING...ENDING EARLY SUNDAY MORNING. LOW-LEVEL MIXING
RATIOS IN EXCESS OF 8 G/KG WILL SUPPORT ISOLATED TO SCATTERED
THUNDERSTORMS DURING THE AFTERNOON AND EVENING. THE STRONGEST STORMS
WILL BE CAPABLE OF PRODUCING WINDS IN EXCESS OF 40 MPH AND BLOWING
DUST WITH REDUCED VISIBILITIES. LATEST GUIDANCE IS HINTING THAT THE
ACTIVITY WILL CONTINUE WESTWARD OVERNIGHT AND INTO EARLY MONDAY
MORNING ACROSS SE CA.

ANOTHER ACTIVE DAY EXPECTED FOR THE 4TH OF JULY. STRONG MOISTURE
FLUX WILL AGAIN SUPPORT SCATTERED AFTERNOON AND EVENING
THUNDERSTORMS. GUIDANCE IS LIKELY FAILING TO ACCOUNT FOR THE
PRESENCE OF CONVECTION AND TEMPERATURES APPEAR TO BE TOO HIGH.
OFFICIAL FORECAST IS AGAIN WEIGHTED HEAVILY TOWARDS THE COOLER
ECMWF...RESULTING IN A DROP OF 5 TO 7 DEGREES FROM THE PREVIOUS
FORECAST.

TUE-SAT...CONDITIONS WILL REMAIN FAVORABLE FOR THUNDERSTORM ACTIVITY
THROUGH MUCH OF THE WEEK AS THE MONSOON HIGH REMAINS POSITIONED TO
OUR NORTH AND EAST. LATEST GFS/ECMWF ALSO SUGGEST THAT CONVECTION
MAY BE ENHANCED BY A CONTINENTAL PV FRACTURE TUE-THU. SLIGHTLY
WARMER AND DRIER CONDITIONS ARE EXPECTED LATE IN THE WEEK AS THE
FLOW BECOMES MORE SOUTHWESTERLY AHEAD OF A TROUGH ALONG THE WEST
COAST.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX AND KIWA AIRFIELDS...
EAST AND SOUTHEAST WINDS ARE EXPECTED TO CONTINUE THROUGH THE
EVENING HOURS. ISOLATED THUNDERSTORMS ARE POSSIBLE OVER THE HIGHER
TERRAIN EAST OF PHOENIX WHICH COULD PRODUCE GUSTY OUTFLOW WINDS
LATER THIS AFTERNOON INTO THIS EVENING. THERE IS A CHANCE FOR
LOWERED VISIBILITIES NEAR 5SM WITH SOME BLOWING DUST OR HAZE DUE TO
THE STRONG OUTFLOWS AND HAVE INCLUDED A TEMPO GROUP DUE TO THE
UNCERTAINTY OF EXACT TIMING.

SOUTHWEST ARIZONA AND AND FAR SOUTHEAST CALIFORNIA INCLUDING
KIPL...AND KBLH AIRFIELDS...
DIURNAL WIND PATTERNS ARE EXPECTED TO CONITINUE THROUGH THE
REMAINDER OF THE DAY WITH MODELS INDICATING A GULF SURGE DEVELOPING
AFTER 06Z TONIGHT BRINGING ENHANCED SOUTH AND SOUTHEAST BREEZINESS.
REMNANT MID TO HIGH LEVEL CLOUDS FROM DISTANT THUNDERSTORMS WILL
LIKELY MOVE IN LATE TONIGHT AS WELL.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
TUESDAY THROUGH SATURDAY...
A MONSOON PATTERN WILL BE IN PLACE THIS COMING WEEK WITH A FOUR
CORNERS HIGH LEADING TO EAST AND SOUTHEAST FLOW ALOFT. THERE WILL BE
AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS EACH DAY. THERE WILL BE
FLUCTUATIONS IN HUMIDITIES FROM DAY TO DAY BUT OVERALL...MINIMUM
HUMIDITIES ARE EXPECTED TO REMAIN AT OR ABOVE 15 PERCENT THROUGH
WEDNESDAY BEFORE SLOWLY DECLINING. SIMILAR TRENDS CAN BE EXPECTED IN
THE MAX HUMIDITIES. AS IS TYPICAL...MOST STORMS WILL PRODUCE MORE
WIND...WITH SOME POSSIBLE BLOWING DUST...THAN RAIN BUT WETTING RAIN
WILL BE POSSIBLE WITH INDIVIDUAL THUNDERSTORMS.
