AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
255 PM MST SAT APR 14 2007

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

.SYNOPSIS...
A QUICK MOVING HIGH PRESSURE SYSTEM WILL CROSS THE REGION TODAY...
LEADING TO CONSIDERABLY WARMER TEMPERATURES TODAY AND SUNNY
CONDITIONS. A LOW PRESSURE SYSTEM WILL BEGIN MOVING INTO SOUTHERN
CALIFORNIA LATE TONIGHT...THEN SLOWLY CROSS ARIZONA THROUGH MONDAY.
THE MAIN IMPACTS OF THE SYSTEM WILL BE WINDY AND COOLER WEATHER
SUNDAY INTO MONDAY...WITH AREAS OF BLOWING DUST POSSIBLE SUNDAY
ACROSS THE LOWER DESERTS. THERE WILL ALSO BE A SLIGHT CHANCE OF
SHOWERS...MAINLY SUNDAY NIGHT AND MONDAY MORNING. THIS SYSTEM WILL
BE FOLLOWED BY HIGHER PRESSURE FOR SUNNY AND WARMER WEATHER TUESDAY
THROUGH MIDWEEK ALONG WITH BREEZY CONDITIONS AT TIMES.

&&

.SHORT TERM...
TONIGHT THROUGH TUESDAY...
WATER VAPOR SATELLITE IMAGERY SHOWS NEXT STORM SYSTEM IS MOVING ON
TO THE CALIFORNIA SHORE AT THIS TIME. VISIBLE AND INFRARED IMAGERY
SHOW BAND OF HIGH CLOUDS ASSOCIATED WITH PARENT LOW ALREADY MOVING
OVER MUCH OF THE CWA. SURFACE OBSERVATIONS SHOW PLENTY OF LOW LEVEL
MOISTURE CURRENTLY WITH THE SYSTEM ON THE WEST SIDE OF THE COASTAL
MOUNTAINS. BUT A VERY DRY AIRMASS REMAINS IN PLACE OVER THE
MOUNTAINS AND DESERTS...WITH WIDESPREAD DEW POINTS IN THE TEENS.

MODELS CONTINUE TO SLOW DOWN THE PROGRESSION OF THE SYSTEM FOR
SUNDAY AND MONDAY. THIS WAS ANTICIPATED YESTERDAY...AND I/M GLAD TO
SEE IT/S PANNING OUT. THE FORECAST MAY PLAY OUT A LITTLE SLOWER THAN
THE MODELS ARE STILL INDICATING...BUT AT LEAST THEY HAVE A BETTER
HANDLE ON IT TODAY AS COMPARED TO YESTERDAY. STILL THINKING THAT THE
SYSTEMS FORWARD PROGRESSION WILL BE DICTATED BY THE DEVELOPMENT OF
THE LARGE H5 LOW OVER THE NORTHEAST CONUS.

H5 LOW EVOLVES...CUTS OFF...AND MOVES OVER SOUTHERN CALIFORNIA BY
SUNDAY AFTERNOON. ONLY HAVE PRECIP CHANCES ACROSS SOUTHERN
CALIFORNIA FOR SUNDAY AFTERNOON RIGHT NOW. AIRMASS AHEAD OF THE LOW
WILL REQUIRE SOME TIME TO SATURATE. ALSO THINKING THAT WE/LL HAVE
BETTER CHANCES NEAR THE CENTER OF THE LOW...WHERE INSTABILITY WILL
BE MAXIMIZED AND SOME MOISTURE WILL BE AVAILABLE.

LOW CONTINUES TO JAUNT FORWARD THROUGH SUNDAY NIGHT. AS IT DOES...I
EXPECT SHOWERS TO BEGIN BLOSSOMING OVER THE CENTRAL/EASTERN PORTIONS
OF THE CWA. MAY SEE A DECREASE IN SHOWERS DURING THE MID TO LATE
MORNING HOURS MONDAY...WITH ANOTHER INCREASE IN ACTIVITY MONDAY
AFTERNOON AS THERMALLY DRIVEN INSTABILITY COMBINES WITH THE SYNOPTIC
FORCING TO CREATE SHOWERS WITH EMBEDDED THUNDERSTORMS. PRECIP SHOULD
BE ENDING ACROSS THE WESTERN CWA /SRN CA/ AS MONDAY WEARS ON.

PRECIP CHANCES LINGER OVER THE HIGHER TERRAIN OF THE EASTERN CWA
MONDAY NIGHT/TUESDAY MORNING. LATER SHIFTS WILL LIKELY HAVE TO
REVISE THESE POPS AS THEY ARE COMPLETELY DEPENDANT ON THE SYSTEM/S
FORWARD SPEED. SNOW LEVELS LOOK LIKE THEY WILL REMAIN IN THE 5500
FOOT RANGE...WHICH WOULD EFFECT A RATHER SMALL PORTION OF OUR AREA.

OTHER WEATHER CONCERNS...WINDS NOT LOOKING AS IMPRESSIVE SUNDAY.
WE/LL STILL SEE WIDESPREAD BREEZY TO WINDY CONDITIONS...BUT NOT
EXPECTING A REPEAT PERFORMANCE OF LAST WEEK/S WINDY SYSTEM. STILL
HAVE A MENTION OF AREAS OF BLOWING DUST IN THE GRIDS /SE CA AND SW
AZ HAVEN/T SEEN ANY DECENT PRECIP IN QUITE A WHILE/...BUT DIDN/T
ATTACH A VISIBILITY QUALIFIER.

MAXIMUM TEMPERATURES SUNDAY WILL BE APPROACHING A FULL 20 DEGREES
COOLER ACROSS SE CA AS COMPARED TO TODAY. MAXIMUM TEMPERATURES
ACROSS CENTRAL AND SOUTH-CENTRAL ARIZONA WILL BE A BIT MORE TRICKY
SUNDAY AS THEY WILL BE PREDICATED ON THE LOW/S MOVEMENT. WITH THE
SLOWER EVOLUTION EXPECTED...RAISED MAX TEMPS A FEW ACROSS EASTERN
CWA. FOR MONDAY...JUST THE OPPOSITE. COOLER MAX TEMPS EXPECTED OVER
THE EAST DUE TO CLOUDS/SHOWERS...WITH WARMING ALREADY STARTING OVER
SE CA. WARMER MAX TEMPS YET CWA-WIDE TUESDAY AS RIDGE MOVES IN.

MIN TEMPS SLIGHTLY WARMER SUNDAY DUE TO HIGH CLOUDS...COOLER MONDAY
WITH PRECIP. FOR TUESDAY...WILL BE TOUGH AS CLOUDS WILL BE LINGERING
OVER THE EAST AND DRIER AIR WILL BE MOVING INTO THE WEST...SO PLAYED
IT CONSERVATIVE FOR NOW.

&&

.LONG TERM...
TUESDAY NIGHT THROUGH SATURDAY...
DRIER ZONAL FLOW LATE TUESDAY NIGHT OVER THE DESERT SOUTHWEST...
AHEAD OF THE NEXT UPPER LEVEL TROF OVER THE PAC NW. THIS TROF ENERGY
DROPS SOUTH THROUGH THE GREAT BASIN...AND SWINGS THROUGH NORTHERN
ARIZONA WEDNESDAY INTO THURSDAY. OF NOTE IS AN AMPLIFIED RIDGE OVER
THE CENTRAL CONUS THAT FORMS A BLOCK...BOTH GFS/EURO SHOW 564DM
HEIGHTS WELL NORTH INTO THE ONTARIO CANADIAN PROVENCE. THIS PATTERN
SERVES TO BROADEN THE SHORT WAVE TROF OVER THE WESTERN CONUS...AND
ALLOWS MORE ENERGY TO PUSH SOUTH AND WEST WITH TIME. CURRENTLY...
MODELS INDICATE LITTLE MOISTURE ASSOCIATED WITH THIS TROF. SO...
ELECTED TO KEEP THE FORECAST DRY THROUGH THE EXTENDED...AND JUST
INTRODUCE BREEZY CONDITIONS CWA-WIDE WEDNESDAY...AND POSSIBLY AGAIN
FRIDAY ALONG WITH SOME INCREASED MOISTURE AND CLOUDINESS...TRENDING
DOWN MAX TEMPS A FEW DEGREES INTO THE UPPER 80S THROUGHOUT THE
EXTENDED.

&&

.AVIATION...
VFR CONDS WILL BE THE RULE AT ALL TAF SITES TONIGHT AND INTO SUNDAY.

NEXT TROUGH SYSTEM CURRENTLY TAKING SHAPE ALONG THE CENTRAL/SRN CA
COAST WILL GIVE AN INCREASE IN WINDS AT ALL TAF SITES NEXT 24 HRS.
MSTR WILL BE LACKING WITH THIS SYSTEM...AT LEAST INITIALLY...SO NO
CIGS BLO 6K ANTICIPATED THRU 00Z MONDAY. PERHAPS SOME ISOLD AREAS OF
BLOWING DUST/SAND COULD BRING VSBYS LCLY 3-5SM AT WRN TAF SITES
AFTER 20Z OR SO.

SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL
FOR MORE DETAILED INFORMATION.

AVIATION DISCUSSION IS NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
TROUGH SYSTEM DEVELOPING ALONG THE CENTRAL/SRN CA COAST WILL FOR
SURE BRING AN INCREASE IN SURFACE WINDS...CLOSE TO CRITICAL FIRE WX
THRESHOLDS DURING THE DAY SUNDAY. HOWEVER...HUMIDITIES ARE ALSO
EXPECTED TO RISE DURING THE DAY AS THE SYSTEM NEARS...ESPECIALLY
OVER SE CA FIRE WEATHER ZONES. FURTHER TO THE E...IT COULD GET DICEY
OVER SCNTRL AZ...WITH SUFFICIENTLY LOW HUMIDITIES...BUT MARGINAL
WINDS. AT PRESENT TIME...CONFIDENCE IS NOT HIGH ENOUGH TO SWITCH
CURRENTLY WATCH TO A RED FLAG WARNING FOR SCNTRL FIRE WX ZONE 132...
SO WILL LEAVE AS WATCH FOR NOW AND LET MID SHIFT RE-EVALUATE THE
SITUATION WITH LATEST MODEL GUIDANCE IN HAND.

MEANWHILE...YET ANOTHER LOW PRESSURE SYSTEM WILL APPROACH THE DESERT
SW BY THE MIDDLE OF NEXT WEEK...POSSIBLY RESULTING IN ANOTHER BOUT
OF STRONG WINDS...LOW HUMIDITIES AND RESULTANT FIRE WEATHER
CONCERNS. MORE ON THIS IN LATER DISCUSSIONS.
