AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
320 PM MST MON AUG 13 2012

.SYNOPSIS...
STRONG HIGH PRESSURE WILL CONTINUE OVER THE DESERT SOUTHWEST THROUGH
TUESDAY...RESULTING IN WELL ABOVE NORMAL TEMPERATURES AND PERIODS OF
EXCESSIVE HEAT. MONSOON MOISTURE WILL SLOWLY SPREAD BACK INTO THE
REGION STARTING LATE WEDNESDAY...RESULTING IN AN GRADUAL INCREASING
THREAT OF AFTERNOON THUNDERSTORM ACTIVITY OVER SOUTHEAST CALIFORNIA
AND SOUTHWEST ARIZONA THROUGH THE WEEKEND. THE BEST CHANCES OF
AFTERNOON AND EVENING THUNDERSTORM ACTIVITY ACROSS SOUTH CENTRAL
ARIZONA LOOK TO BE THURSDAY INTO SATURDAY.

&&

.DISCUSSION...
THE DAY IS SHAPING UP LIKE A TYPICAL MONSOON AFTERNOON IN
AUGUST...WITH EXTREMELY WARM TEMPERATURES AND ISOLATED STORM
DEVELOPMENT DOTTING THE DESERT LANDSCAPE. THE REGION AGAIN FALLS
UNDER THE INFLUENCE OF A 300MB CUT OFF CIRCULATION /THAT HAS
REMAINED MOSTLY STATIONARY/ OVER NORTHERN BAJA AND THE UPPER LEVEL
RIDGE TO OUR EAST ACROSS NEW MEXICO. OVERALL MOTION ON A LOOPED
WATER VAPOR SAT LOOKS VERY SIMILAR TO YESTERDAYS WITH SOMEWHAT
WEAK DIFLUENT FLOW NORTH OF THE FORECAST AREA. EARLIER THIS MORNING
A PASSING OUTFLOW/GRAVITY WAVE FROM NEW MEXICO TREKKED TO THE WEST
ACROSS THE SOUTHERN PORTION OF THE STATE...TRIGGERING MID MORNING
ISOLATED /POP-CORN OR PULSE/ STORMS ACROSS THE WESTERN DESERTS. DUE
TO THE IMPRESSIVE HEAT OBSERVED SO FAR TODAY...EXPECT PULSING STORM
DEVELOPMENT TO CONTINUE INTO THE EARLY EVENING WITH SOME STRONGER
ISOLATED STORMS...WITH MOST THUNDERSHOWERS HAVE PERIODS OF BRIEF
HEAVY RAIN...LIGHTNING AND SOME GUSTY WINDS. STEERING FLOW ALOFT IS
FAIRLY LIGHT...VARIABLE IN DIRECTION WITH 5 TO 10 KTS TOTAL VELOCITY
WHICH IS EVIDENT ON BOTH THE STORM MOTION ON THE RADAR AND FROM THIS
MORNING/S SOUNDINGS. NO DISCERNIBLE UPPER LEVEL SUPPORT TO HELP
PERSIST STORMS OVERNIGHT...SO POPS DROP BACK TO SINGLE DIGIT VALUES
AFTER 06Z ACROSS MUCH OF AZ. CHOSE TO KEEP SOME SLIGHT CHANCE
MENTION ALONG THE LOWER COLORADO RIVER OVERNIGHT...PROXIMITY TO THE
UPPER LOW AND SOME PERSISTENT MOISTURE COULD SUSTAIN SHOWERS
OVERNIGHT IN THAT AREA.

RIDGE THICKNESSES SHOW NOT MUCH CHANGE BETWEEN VALUES FORECAST FOR
TODAY AND TOMORROW...REACHING 588-589DM BOTH AFTERNOONS. GIVEN
THAT...ADJUSTED FORECAST TEMPS FOR TOMORROW GENERALLY UP A DEGREE OR
TWO. OVERNIGHT LOWS TONIGHT COULD BE TRICKY IF CLOUDS FROM THIS
AFTERNOON/S CONVECTIVE PERSIST AND INSULATE THE LOWER DESERTS.
DESPITE ANY CHALLENGES TO THE FORECAST DUE TO LINGERING CLOUDS...IT
WILL BE ANOTHER WARM MORNING ACROSS THE AREA LEADING INTO ANOTHER
EXTREMELY WARM DAY. THE EXCESSIVE HEAT WARNING WILL CONTINUE THROUGH
WEDNESDAY AM. CONDITIONS TOMORROW APPEAR SIMILAR TO TODAY...HOT
CONDITIONS LEADING TO AFTERNOON PULSE CONVECTIVE ACTIVITY ACROSS THE
REGION. MOISTURE LEVELS ARE NOT THE BEST FOR SUSTAINED STORMS...BUT
MODEL SOUNDING PWATS SUSTAIN AN INCH OR GREATER THROUGHOUT THE
REGION. EXPECT CONVECTION TO INITIATE OVER THE HIGHER TERRAIN
EARLIER BEFORE THE LOWER DESERTS REACH PEAK HEATING IN THE
AFTERNOON.

WEDNESDAY THROUGH SUNDAY...
MEDIUM RANGE MODELS CONTINUE TO CALL FOR A SUBSTANTIAL MOISTURE
INCREASE TO OCCUR BEGINNING WEDNESDAY AND CONTINUING INTO THE
WEEKEND...ALLOWING FOR A MARKED UPSWING IN THUNDERSTORM CHANCES.
UPPER HIGH IS FORECAST TO SHIFT INTO NWRN ARIZONA OR SRN NEVADA
GIVING A MORE FAVORABLE ELY OR NELY STEERING FLOW TO THE LOWER
DESERTS. AN INVERTED TROF SLOWLY WORKING NORTHWESTWARD ALONG THE SRN
BAJA COAST WILL HELP SPREAD MOISTURE TO THE NORTH AND INTO MEXICO
AND SRN AZ. BY THURSDAY EXPECT CHANCE POPS ACROSS SOUTH CENTRAL AZ
WITH 10 TO 20 PERCENT CHANCES OVER THE SWRN AZ AND SERN CA DESERT
EACH DAY. HIGH TEMPERATURES WILL FALL MARKEDLY GIVEN THE EXPECTED
INCREASE IN MOISTURE...CLOUDS AND SHOWERS...AND BY THURSDAY MUCH OF
THE LOWER DESERT WILL EXPERIENCE HIGHS IN THE VICINITY OF SEASONAL
NORMALS. LATEST GFS/ECMWF GUIDANCE IS ACTUALLY BACKING OFF ON THE
MOISTURE INCREASE SLIGHTLY AND MEX/ECE MOS TEMPS ARE NOT QUITE AS
COOL AS PREVIOUS RUNS SUGGESTED SO WE WILL RAISE HIGHS A COUPLE
DEGREES OR SO THURSDAY INTO THE WEEKEND AND KEEP THE MAX READINGS
CLOSE TO SEASONAL NORMALS INSTEAD OF 2-3 DEGREES BELOW. THERE IS
ALWAYS THE CHANCE THAT IF A SIGNIFICANT CONVECTIVE OUTBREAK OCCURS
SOMETIME DURING THE LATTER HALF OF THE WEEK...LOWS MAY DROP TO NEAR
OR EVEN BELOW 100 IN AREAS OF SIGNIFICANT RAIN.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
THROUGH 04Z TUE...VERY ISOLATED THUNDERSTORMS EXPECTED AROUND THE
OUTSKIRTS OF THE GREATER PHOENIX AREA. THIS COULD FORCE GUSTY
OUTFLOW WINDS FROM ANY DIRECTION FOR A SHORT TIME. OTHERWISE
VARIABLE WINDS UNDER 10 KNOTS. FROM 04Z TUE THROUGH 19Z TUE...SCT
CLOUDS AOA 15 THSD MSL. LIGHT WINDS UNDER 10 KNOTS.

SOUTHEAST CA AND SOUTHWEST AZ...INCLUDING KIPL AND KBLH...
THROUGH 04Z TUE...VERY ISOLATED THUNDERSTORMS...MORE NUMEROUS OVER
THE MTNS WEST AND SOUTHWEST OF KIPL. TSTMS COULD DEVELOP GUSTY
OUTFLOW WINDS FROM ANY DIRECTION FOR A SHORT TIME...GUSTS TO NEAR
35KTS.  OTHERWISE VARIABLE WINDS UNDER 10 KNOTS. FROM 04Z TUE
THROUGH 19Z TUE...SCT CLOUDS AOA 15 THSD MSL. LIGHT WINDS UNDER 10
KNOTS.
