AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
500 PM MST WED JUN 27 2012

.UPDATE...AVIATION WEATHER DISCUSSION.

&&

.SYNOPSIS...
THE ATMOSPHERE WILL BEGIN TO DRY OUT OVER THE NEXT FEW DAYS AS HIGH
PRESSURE ALOFT SLOWLY STRENGTHENS. THERE WILL BE A SLIGHT CHANCE OF
AN AFTERNOON OR EVENING THUNDERSTORM RESTRICTED MAINLY OVER THE
HIGHER TERRAIN OF SOUTH-CENTRAL ARIZONA BOTH TODAY AND ON THURSDAY.
VERY WARM OVERNIGHT LOWS AND HOT AFTERNOON TEMPERATURES WILL RESULT
IN THE POTENTIAL FOR EXCESSIVE HEAT ACROSS MUCH OF THE ARIZONA
DESERT THE REST OF THIS WEEK AND INTO THE EARLY WEEKEND.

&&

.DISCUSSION...
DEEPEST MOISTURE AND MOST INSTABILITY ONCE AGAIN IS OVER EXTREME
SOUTHEAST ARIZONA. SATELLITE AND RADAR SHOW THUNDERSTORMS DEVELOPING
SOUTHEAST OF TUCSON...ALONG THE INTERNATIONAL BORDER AND OVER THE
RIM. ONCE AGAIN BIGGEST THREAT FOR OUR FORECAST AREA WILL BE BLOWING
DUST KICKED UP BY BOUNDARIES PROPAGATING NORTHWARD FROM THE STORMS
TO THE SOUTH. MESOSCALE FORECAST MODELS KEEP CONVECTION PRETTY MUCH
OUTSIDE OUR COUNTY WARNING AREA...THOUGH THEY DO INDICATE SOME
BOUNDARIES MOVING INTO THE AREA. MODEL PERFORMANCE OVER THE LAST
SEVERAL DAYS HAS NOT BEEN REAL GOOD IN HANDLING THESE SO CONFIDENCE
IS NOT REAL HIGH. YESTERDAY WE DID GET SOME DUST FROM OUTFLOW
GENERATED BY STORMS TO OUR SOUTH...SO THERE IS A DEFINITE
POSSIBILITY WE'LL SEE SOMETHING SIMILAR TONIGHT. DEWPOINTS IN THE
LOWER DESERT THIS AFTERNOON HAVE BEEN RUNNING IN THE LOW 50S. THIS
MAY HELP THE BOUNDARIES TO MOVE FURTHER NORTH INTO THE REGION.

THERE WILL BE A DWINDLING CHANCE ON SHOWERS AND STORMS FOR THE
REMAINDER OF THE WEEK...AS THE RIDGE BUILDS BACK TO THE WEST OVER
ARIZONA...EFFECTIVELY SHUTTING OFF THE FLOW OF MOISTURE INTO THE
REGION. MODEL SOUNDINGS SHOW DECREASING PWAT THU THRU THE END OF THE
WEEKEND. BOTH THE GFS AND ECMWF ARE IN REASONABLE AGREEMENT WITH THE
FORECAST POSITION AND STRENGTH OF THE RIDGE...WITH BOTH SHOWING A
595 DM CENTER OVER SOUTHEAST ARIZONA ON FRIDAY. EXCESSIVE HEAT WILL
BECOME THE PRIMARY CONCERN OVER THE NEXT TWO TO THREE DAYS.
ALTHOUGH THE AFTERNOON HIGH TEMPERATURES WILL BE JUST SHY OF
EXCESSIVE HEAT WARNING CRITERIA...THE COMBINATION OF THESE
TEMPERATURES WITH EXCEPTIONALLY WARM LOWS IN THE UPPER 80S TO NEAR
90 WILL MAKE THE HEAT OPPRESSIVE. AN EXCESSIVE HEAT WARNING IS IN
EFFECT RIGHT NOW THROUGH FRIDAY AT 8 PM. A WATCH OR WARNING MAY ALSO
BE NEEDED FOR SATURDAY.

A STORM SYSTEM APPROACHING THE PACIFIC NORTHWEST WILL CAUSE THE HIGH
PRESSURE TO SHIFT ITS POSITION EARLY NEXT WEEK...POSSIBLY ALLOWING A
RETURN OF SHOWERS AND STORMS TO THE REGION BY NEXT TUESDAY. THIS IS
QUITE A WAYS OUT THOUGH AND THERE IS SOME DISPARITY ATM BETWEEN
MODELS ON THE AMOUNT OF MOISTURE THAT WILL WORK ITS WAY INTO
ARIZONA. FOR NOW...RETAINED THE NEAR CLIMO POPS INHERITED FROM OUR
EARLIER FORECAST PACKAGE.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA...INCLUDING KPHX...KIWA...AND KSDL...

THROUGH 03Z THU...ISOLATED THUNDERSTORMS 30-50 MILES SOUTH OF
PHOENIX WILL LIKELY GENERATE NORTHWARD MOVING CONVECTIVE OUTFLOW
BOUNDARIES 15 TO 20 KTS WITH BLOWING DUST UNDER 2 MILES AT TIMES.
03Z THU TO 17Z THU...SOUTH TO SOUTHEAST WIND UNDER 10 KNOTS...SCT
CLOUDS AOA 14 THSD MSL.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...

MOSTLY CLEAR SKIES AND DIURNAL WIND PATTERNS WILL PERSIST THROUGH
THURSDAY. ANTICIPATE OCCASIONAL GUSTINESS BETWEEN 23Z AND 03Z.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SATURDAY THROUGH WEDNESDAY...
HIGH PRESSURE WILL BE CENTERED OVER THE ARIZONA/NEW MEXICO REGION
THROUGH THE WEEKEND WITH LITTLE IF ANY THUNDERSTORM ACTIVITY OVER
ARIZONA...LET ALONE SOUTHEAST CALIFORNIA. HUMIDITIES WILL REMAIN LOW
WITH FAIR TO POOR OVERNIGHT RECOVERY. AN INCREASE IN MOISTURE ALOFT
ALONG WITH THUNDERSTORM CHANCES IS ANTICIPATED AS EARLY AS MONDAY
WHICH WILL HELP IMPROVE OVERNIGHT HUMIDITY RECOVERY.
HOWEVER...EXPECT STORMS CHANCES OVER THE FORECAST AREA TO REMAIN
CONFINED TO THE HIGHER TERRAIN OF SOUTH-CENTRAL ARIZONA.
OTHERWISE...FAMILIAR WARM SEASON DIURNAL WIND PATTERNS CAN BE
EXPECTED...FAVORING SOUTHWEST AND WEST DIRECTIONS IN THE AFTERNOON
AND EVENINGS.
