AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
936 AM MST THU MAR 7 2013

.SYNOPSIS...
ANOTHER MILD DAY WILL BE IN STORE TODAY BEFORE MUCH COOLER
TEMPERATURES ARRIVE FRIDAY AS A STRONG LOW PRESSURE SYSTEM MOVES
THROUGH THE SOUTHWEST. THIS SYSTEM WILL ALSO BRING VERY GOOD CHANCES
OF PRECIPITATION TO MUCH OF THE REGION IN THE THURSDAY NIGHT THROUGH
FRIDAY NIGHT TIME FRAME...ALONG WITH A CHANCE OF THUNDERSTORMS.
LINGERING CHANCES FOR PRECIPITATION ARE EXPECTED FOR SATURDAY MAINLY
ACROSS SOUTH-CENTRAL ARIZONA. THE COOL TEMPERATURES WILL LAST
THROUGH SATURDAY...BUT THEN QUICKLY REBOUND BY EARLY NEXT WEEK AS
HIGH PRESSURE RETURNS.

&&

.DISCUSSION...
MID MORNING WATER VAPOR IMAGERY DEPICTS A LARGE UPPER LEVEL TROUGH
OFF THE COAST OF SAN FRANSISCO...WITH AN ELONGATED AREA OF MID LEVEL
MOISTURE STRETCHING FROM THE EASTERN PACIFIC INTO IDAHO. MEANWHILE A
LARGE PLUME OF SUBTROPICAL MOISTURE IS STREAMING NORTHWARD THROUGH
BAJA...SONORA...NEW MEXICO...AND TEXAS BUT ACROSS OUR FORECAST
AREA...CONDITIONS REMAIN QUIET AND DRY. NOT MUCH IN THE WAY OF CLOUD
COVER AT THIS POINT...THE THICKER MID AND HIGH CLOUDS ARE STILL OFF
TO THE WEST AS OF 16Z. CONSEQUENTLY...I MADE MINOR CHANGES TO THE
SKY GRIDS FOR THE REST OF THE DAY TO PAINT A MORE
OPTIMISTIC...MOSTLY SUNNY FORECAST. TEMPS SHOULD STILL BE ABLE TO
REACH THE UPPER 70S TO LOWER 80S TODAY...BASICALLY A NEAR COPY OF
YESTERDAY\S TEMPS.

INCOMING 12Z MODEL DATA CONTINUES TO INDICATE A RAPID TRANSITION
AWAY FROM THE SUNNY SKIES AND WARM TEMPS WE\VE BEEN EXPERIENCING ALL
WEEK. SHOWERS ARE EXPECTED TO BREAK OUT LATE TONIGHT WITH A
SECONDARY /MORE WIDESPREAD/ ROUND OF SHOWERS TOMORROW AFTERNOON.
FOCUS FOR THE REST OF THE DAY WILL BE ON REFINING POPS AND
DETERMINING ANY WINTER IMPACTS ACROSS OUR FORECAST AREA. AT THIS
POINT IT APPEARS THE ONLY VULNERABLE AREAS FOR SNOWFALL WILL BE THE
HIGHEST ELEVATIONS EAST OF PHOENIX. ELSEWHERE...A HEALTHY QUARTER TO
HALF INCH OF RAIN LOOKS LIKE A GOOD BET.

&&

.PREVIOUS DISCUSSION...
THE STRONG NEGATIVE HEIGHT ANOMALY IS CURRENTLY CENTERED JUST OFF
THE OREGON COAST WITH TWO MAIN PV ANOMALIES NOW ORIENTED TO THE
SOUTH OF THE HEIGHT CENTER. THE SOUTHERN MOST PV ANOMALY CENTERED
ROUGHLY 500NM WEST OF KLAX IS STARTING TO REALLY WRAP UP AND PULL IN
MOISTURE FROM THE SOUTHWEST. A 120KT 300MB JET WILL DIVE SOUTHWARD
INTO THE BACK SIDE OF THE MAIN LONGWAVE TROUGH BY TONIGHT. THESE PV
ANOMALIES AND THE DIVING JET MAX WILL HELP TO DRIVE THE MAIN
LONGWAVE TROUGH SOUTHWARD ALONG THE CALIFORNIA COAST AND TO SHIFT
THE TROUGH FROM A POSITIVE TILT TO A MORE NEUTRAL TILT BY FRIDAY
MORNING. THE LAST SEVERAL MODEL RUNS HAVE BEEN CONSISTENT IN THE
PROGRESSION OF THIS SYSTEM THROUGH SATURDAY. THE MODEL TREND OF
INCREASING THE ATMOSPHERIC MOISTURE CONTENT IS STILL TAKING PLACE
WITH FORECAST PWATS NOW OF AROUND THREE QUARTERS OF AN INCH ACROSS
THE CWA ON FRIDAY.

UPPER DYNAMICS WITH THIS IMPRESSIVE LOW WILL BE QUITE STRONG
STARTING LATE THURSDAY NIGHT OVER SOUTHEAST CALIFORNIA AND THEN INTO
THE DAYTIME HOURS FRIDAY ACROSS SOUTHERN ARIZONA. LARGE SCALE ASCENT
WILL INCREASE ACROSS THE ENTIRE REGION BY EARLY FRIDAY MORNING AS
SHOWN BY INCREASING Q-VECTOR CONVERGENCE AND MODEST UPPER DIFLUENCE.
THIS WILL BE IN ADDITION TO THE STRONG MOISTURE ADVECTION AND MODEST
MID-LEVEL ISENTROPIC LIFT. THESE FACTORS ARE EXPECTED TO PROMOTE
WIDESPREAD SHOWER DEVELOPMENT STARTING AFTER MIDNIGHT IN WESTERN
ZONES AND THEN SPREADING EASTWARD ACROSS THE MAJORITY OF
SOUTH-CENTRAL ARIZONA BY DAYBREAK FRIDAY. THE BEST DYNAMICS COME
INTO PLAY STARTING LATE FRIDAY MORNING AND LASTING THROUGH THE
AFTERNOON HOURS AS THE MAIN PV ANOMALY MARCHES ACROSS THE REGION.

THE VERY COLD MID LEVEL TEMPERATURES ASSOCIATED WITH THIS
SYSTEM...AROUND -30C AT 500MB...WILL PROVIDE FOR FAVORABLE SOUNDING
PROFILES WHICH SHOULD LEAD TO SCATTERED THUNDERSTORM DEVELOPMENT
ACROSS THE REGION AFTER 12Z FRIDAY. MODEL SOUNDINGS INDICATE UP TO
600 J/KG OF CAPE AND LI/S OF -2 WILL BE POSSIBLE FRIDAY AFTERNOON
ACROSS SOUTH-CENTRAL ARIZONA. GIVEN THE POTENTIAL UNSTABLE
ENVIRONMENT AND FAIRLY STRONG SHEARED WIND PROFILES...THERE WILL BE
SOME POTENTIAL FOR STRONG GUSTY WINDS AND SMALL HAIL WITH A FEW OF
THE STRONGEST THUNDERSTORMS. WINDS ALOFT WILL NOT BE OVERLY
STRONG...ON THE ORDER OF 30KTS...BUT WITH SOME EVAPORATIVE COOLING
AND MOMENTUM TRANSFER...ISOLATED THUNDERSTORM GUSTS OF UP TO 45 MPH
WILL BE POSSIBLE. FORECAST QPF AMOUNTS ARE STILL LOOKING LIKE A
GENERAL QUARTER TO A THIRD OF AN INCH ACROSS THE DESERTS OF
SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA. HIGHER AMOUNTS ARE
EXPECTED OVER THE SOUTH-CENTRAL ARIZONA DESERTS WITH A BASIN AVERAGE
OF AROUND A HALF AN INCH WITH AMOUNTS CLOSER TO AN INCH IN FAVORED
UPSLOPE AREAS NORTH AND EAST OF PHOENIX.

THE MAIN COLD FRONT WILL SLIDE THROUGH WESTERN ZONES BY LATE FRIDAY
MORNING AND DURING THE AFTERNOON AND EARLY EVENING ACROSS SOUTHERN
ARIZONA. PRECIPITATION CHANCES WILL DROP OFF AFTER FROPA...BUT
RESIDUAL WRAP AROUND MOISTURE AND PRECIPITATION CHANCES WILL LINGER
AT LEAST INTO SATURDAY. SNOW LEVELS WILL DROP TO AROUND 4000 FEET BY
MIDNIGHT FRIDAY...WITH RAIN CHANGING TO SNOW ACROSS HIGH TERRAIN
AREAS IN NORTHEAST MARICOPA AND SOUTHERN GILA COUNTIES. THERE IS
STILL SOME QUESTION WITH SNOW AMOUNTS...BUT CURRENT THINKING IS
ELEVATIONS ABOVE 5000 FEET COULD SEE 2-3 INCHES WITH SLIGHTLY
HIGHER AMOUNTS FOR THE HIGHEST PEAKS. LIGHTER AMOUNTS OF UP TO AN
INCH IS EXPECTED AT ELEVATIONS BETWEEN 4000-5000 FEET FRIDAY NIGHT.

THE DEEP TROUGH WILL LINGER LONG ENOUGH INTO SATURDAY TO EXPECT SOME
INSTABILITY SHOWERS WITH HIGHEST CHANCES NORTH AND EAST OF PHOENIX.
AFTER SATURDAY...MODELS INDICATE A QUICK BUILD UP OF HEIGHTS AND
WARMING TEMPERATURES. THERE IS SOME MODEL DIFFERENCES BY THE MIDDLE
OF NEXT WEEK WITH THE GFS BEING THE SLIGHTLY COOLER OUTLIER AMONG
LONG RANGE GUIDANCE...SO FOR NOW LEANING TOWARD THE WARMER EUROPEAN.
WILL LIKELY SEE TEMPERATURES IN THE LOWER TO MIDDLE 80S BY TUESDAY
AND POSSIBLY EVEN APPROACHING 90 ACROSS THE SOUTHEAST CALIFORNIA
LOWER DESERTS ON WEDNESDAY. ENSEMBLE GUIDANCE CONTINUES TO POINT
TOWARD A DOMINANT UPPER RIDGE ACROSS THE DESERT SOUTHWEST INTO LATE
NEXT WEEK. THE WARMEST GUIDANCE FOR NEXT THURSDAY ACTUALLY SHOWS
HIGHS POSSIBLY REACHING NEAR RECORD HIGHS FOR AREA.

.AVIATION...
SOUTH-CENTRAL AND SOUTHWEST AZ ARIZONA INCLUDING KPHX...KIWA AND
KSDL...AND SOUTHEAST CA INCLUDING KIPL AND KBLH...

OCCASIONAL HIGH CIRRUS TODAY WILL SUCCUMB TO LOWER CIGS BETWEEN 7K
AND 10K FT BY THE END OF THE TAF PERIOD 12Z FRIDAY. LIGHT WINDS THIS
MORNING OF THE TYPICAL DIURNAL DIRECTION WILL STRENGTHEN BY LATE
AFTERNOON AS THE PRESSURE GRADIENT TIGHTENS AHEAD OF AN APPROACHING
STORM SYSTEM. CENTRAL ARIZONA TERMINALS MAY KEEP MORE OF A S/SW
COMPONENT VERSUS THE TYPICAL WLY DIRECTION DURING THE
AFTERNOON...AND MAY NOT TRULY BECOME E/SE DURING THE OVERNIGHT
(AGAIN KEEPING MORE OF A SLY DIRECTION). A FEW HIGHER GUSTS MAY BE
POSSIBLE ACROSS SERN CALIFORNIA (PARTICULARLY AT KIPL). SCT -SHRA
WILL JUST BE IN THE DEVELOPMENTAL STAGE AT THE END OF THIS TAF
PERIOD...AND HAVE INTRODUCED A VCSH MENTION GIVEN THE UNCERTAINTY IN
EXACT TIMING AND COVERAGE. MAY EVENTUALLY NEED A TEMPO OR
PREDOMINANT GROUPING FOR THE HOURS JUST BEYOND 12Z FRIDAY (AND
CERTAINLY FOR THE FRIDAY AFTERNOON TIME FRAME FOR THE CNTRL ARIZONA
AERODROMES IN FUTURE TAF PACKAGES).

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SATURDAY THROUGH WEDNESDAY...
A TRAILING PIECE OF ENERGY WILL ALLOW FOR ISOLATED TO SCATTERED
SHOWERS SATURDAY AFTERNOON ACROSS CENTRAL ARIZONA...THOUGH MOST
AREAS WILL BE STARTING A PROLONGED DRYING TREND. UNSEASONABLY COOL
TEMPERATURES AND HIGH RELATIVE HUMIDITIES WILL BE COMMON ON
SATURDAY...WITH A MODEST WARMING AND DRYING TREND SUNDAY. A RAPID
SHIFT TOWARDS VERY WARM AND DRY WEATHER WILL BE ON TAP FOR THE
BEGINNING OF NEXT WEEK...WITH AFTERNOON HIGHS SOME 10 DEGREES ABOVE
NORMAL AND MINIMUM HUMIDITIES FALLING INTO THE LOWER TEENS AND
SINGLE DIGITS. FORTUNATELY...DURING THE SAME TIME FRAME IN THE
MIDDLE OF NEXT WEEK...WIND SPEEDS WILL BE UNUSUALLY LIGHT (WELL
BELOW 10 MPH) EVEN IN THE TYPICALLY MORE EXPOSED LOCATIONS.
