AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PHOENIX AZ
955 PM MST MON MAY 19 2008

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

.SYNOPSIS...
AN EXTREME ROLLER COASTER RIDE OF TEMPERATURES WILL OCCUR BY THURSDAY
AS TEMPERATURES PLUMMET 25 TO 30 DEGREES OR MORE FROM THE RECORD
BREAKING HIGHS REACHED MONDAY. ALTHOUGH IT IS EXPECTED TO BE A DEGREE
OR SO LOWER TUESDAY COMPARED WITH MONDAY...RECORD BREAKING HIGHS ARE
STILL EXPECTED. BREEZY TO WINDY WEATHER WILL DEVELOP AGAIN TUESDAY
WITH THE STRONGEST WINDS IN SOUTHEAST CALIFORNIA TUESDAY AFTERNOON
AND EVENING. IT WILL BECOME VERY WINDY OVER THE ENTIRE AREA WEDNESDAY
AND MUCH...MUCH COOLER BY THURSDAY. THE STRONG PACIFIC LOW PRESSURE
SYSTEM THAT WILL BE RESPONSIBLE FOR THE WINDIER AND MUCH...MUCH
COOLER WEATHER WILL ALSO RESULT IN A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS DURING THE LATTER PART OF THE WEEK.

&&

.DISCUSSION...
FORECASTS LOOK REASONABLE WITH ANOTHER EXCESSIVE HEAT WARNING FOR
ALL OF OUR DESERT AREAS FROM 10 AM TO 8 PM TUESDAY.

IT IS STILL EXPECTED TO BECOME BREEZY TO WINDY TUESDAY WITH THE
STRONGEST WINDS IN SOUTHEAST CALIFORNIA. A FIRE WEATHER WATCH IS IN
EFFECT FOR SOUTHEAST CALIFORNIA AND THE LOWER COLORADO RIVER VALLEY
FROM 2 PM TO 11 PM TUESDAY. WINDS LOOK AS IF THEY COULD BE STRONG
ENOUGH TO WARRANT A WIND ADVISORY AS WELL IN PORTIONS OF SOUTHEAST
CALIFORNIA ESPECIALLY JOSHUA TREE NATIONAL PARK.

VERY WINDY WEATHER IS ANTICIPATED ACROSS THE ENTIRE AREA WEDNESDAY.
A FIRE WEATHER WATCH IS IN EFFECT FOR THE ENTIRE AREA FROM 10 AM TO
9 PM WEDNESDAY. A WIND ADVISORY WILL LIKELY BE NEEDED FOR SOUTHEAST
CALIFORNIA AND THE LOWER COLORADO RIVER BEGINNING BY LATE MORNING
AND CONTINUING THROUGH THE AFTERNOON INTO THE EVENING HOURS
WEDNESDAY...AND BY MID AFTERNOON THROUGH THE EVENING HOURS IN
SOUTHWEST AND SOUTH-CENTRAL ARIZONA.

AS THE STRONG LOW PRESSURE SYSTEM CURRENTLY NEAR THE BRITISH
COLUMBIA COAST DEVELOPS SOUTH OVER OUR AREA...TEMPERATURES WILL
PLUMMET 25 TO 30 DEGREES OR MORE COMPARED WITH THE RECORD BREAKING
HIGHS TODAY WITH A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
DEVELOPING ESPECIALLY NORTH AND EAST OF PHOENIX.

PREVIOUS DISCUSSION...
EARLY AFTERNOON TEMPS GENERALLY RUNNING ABOUT 5-7 DEGREES WARMER
THAN 24 HOURS AGO IN SOUTH-CENTRAL ARIZONA AND 0-3 DEGREES WARMER IN
SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA. PHX HAS REACHED 110 SO
FAR. MOS GUIDANCE AND MODEL THERMAL FIELDS INDICATE A LITTLE BIT OF
COOLING FOR TOMORROW BUT NOT ENOUGH TO AVOID RECORD OR NEAR RECORD
HIGH TEMPERATURES AT MOST LOCATIONS. EXCESSIVE HEAT WARNING FOR THE
LOWER ELEVATIONS TUESDAY REMAINS IN EFFECT.

BIG CHANGES REMAIN ON TRACK BEGINNING WEDNESDAY. BOTH GFS AND NAM
SHOW DRY COLD FRONT PUSHING SOUTHWARD THROUGH OUR FORECAST
AREA...REACHING SOUTHEAST ARIZONA BY 00Z THURSDAY. TEMPERATURE DROPS
OF 10-15 DEGREES STILL LOOK GOOD. THE AIRMASS CHANGE WILL ALSO LEAD
TO WINDY CONDITIONS ACROSS THE FORECAST AREA. GFS PROGS THE
ASSOCIATED UPPER LOW TO BECOME CENTERED NEAR LAKE MEAD BY 12Z
THURSDAY. THAT IS WHEN PRECIP CHANCES BEGIN FOR OUR AREA. WITH
COLDER AIR ALOFT PROVIDING INSTABILITY...PRECIP WILL TEND TO BE
CONVECTIVE IN NATURE. GIVEN TRAJECTORY AND TIME OF YEAR...SYSTEM
SHOULD BE LACKING FOR MOISTURE. THUS POPS ARE CONSERVATIVE. OF NOTE
HOWEVER ARE GFS AND ECMWF WHICH PROG ANOMALOUSLY HIGH QPF OVER
PORTIONS OF NORTHERN MARICOPA AND GILA COUNTIES. THIS IS DUE TO
CONSIDERABLE VERTICAL MOTIONS PER THE OMEGA FIELDS AND A LOW LEVEL
CORRIDOR OF MOISTURE COMING OFF THE GULF OF CALIFORNIA. NUDGED POPS
UP SLIGHTLY IN ACKNOWLEDGMENT BUT IN A POST-FRONTAL SITUATION WOULD
NOT COUNT ON THIS LOW LEVEL MOISTURE ADVECTION SCENARIO TO BE AS
ROBUST. WHAT IS MORE CERTAIN IS ADDITIONAL COOLING WITH ANOTHER
10-15 DEGREE DROP THURSDAY. LINGERING MOISTURE AND VORT LOBE
ACTIVITY WILL KEEP SLIGHT CHANCE POPS GOING FRIDAY THOUGH THE UPPER
LOW IS NOW PROGGED BY BOTH GFS AND ECMWF TO WEAKEN AND SHIFT
NORTHEASTWARD AS ANOTHER UPPER LOW APPROACHES FROM THE NORTHWEST
WITHIN THE BROAD TROUGH OVER THE WESTERN STATES. ANTICIPATE LITTLE
CHANGE IN TEMPS. MEANWHILE...THERE WILL BE MUCH LESS WIND THURSDAY
AND FRIDAY.

OVER THE UPCOMING HOLIDAY WEEKEND...THE SECOND UPPER LOW IS
ADVERTISED TO SETTLE OVER CALIFORNIA AND NEVADA BEFORE SHIFTING
NORTHEASTWARD AS A RIDGE OVER THE CENTRAL STATES BEGINS TO EXPAND
WESTWARD. THOUGH CONFIDENCE IS LOW IN ANY PARTICULAR SCENARIO...WILL
TAPER OFF SHOWER THREAT BY SUNDAY...AND BEGIN TO WARM TEMPS BACK UP
SOMEWHAT...STILL ONLY IN THE LOWER 90S AT THE WARMEST SPOTS.

&&

.AVIATION...
KPHX/KIWA AND SURROUNDING AIRFIELDS...LIGHT WINDS TONIGHT AND
TUESDAY MORNING...THEN INCREASING AGAIN FROM THE WEST GENERALLY 15
TO 20 KNOTS WITH GUSTS TO AROUND 25 KNOTS AFTER 2000 GMT UNTIL ABOUT
0100 OR 0200 GMT.

KYUM/KBLH/KIPL...WINDS GENERALLY OF 5 TO 15 KNOTS FROM THE SOUTH OR
SOUTHWEST AT KYUM AND KBLH AND FROM THE SOUTHWEST OR WEST AT KIPL
ARE EXPECTED THROUGH TUESDAY MORNING...THEN WINDS ARE EXPECTED TO
INCREASE FROM THE SOUTHWEST DURING THE AFTERNOON 15 TO 25 KNOTS...AND
AT KBLH AND KIPL GUSTS TO 30 KNOTS ARE MORE ARE EXPECTED...CONTINUING
INTO THE EVENING.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
TUESDAY...WEST WINDS WILL DEVELOP OVER SOUTHEAST CALIFORNIA DURING
THE AFTERNOON...WITH GUSTS IN EXCESS OF 35 MPH POSSIBLE. COMBINED
WITH AFTERNOON RH VALUES BELOW 15 PERCENT...CONDITIONS ARE EXPECTED
TO BECOME FAVORABLE FOR RAPID FIRE GROWTH. AS A RESULT...A FIRE WX
WATCH HAS BEEN ISSUED FOR SOUTHEAST CALIFORNIA AND THE LOWER CO
RIVER VALLEY FOR TUESDAY.

WEDNESDAY...A FIRE WX WATCH FROM SOUTHEAST CALIFORNIA EAST TO
SOUTHERN GILA COUNTY WILL CONTINUE IN EFFECT DUE TO STRONG
WINDS...LOW RH VALUES...AND HIGH FIRE DANGER.

THURSDAY THROUGH THE WEEKEND...A STRONG LOW PRESSURE SYSTEM WILL
MOVE THROUGH THE SOUTHWESTERN STATES THE LATTER PART OF THE WEEK FOR
SIGNIFICANTLY COOLER TEMPERATURES...INCREASING MOISTURE WITH A DAILY
THREAT FOR SHOWERS AND THUNDERSTORMS...AND CONTINUED BREEZY
CONDITIONS.

IF OUTDOOR ACTIVITIES ARE PLANNED...MAKE SURE TO HAVE PLENTY OF
WATER ON HAND TO AVOID DEHYDRATION.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

NEAR-RECORD HIGH TEMPERATURES WILL CONTINUE TUESDAY AS THE HIGH

MOVES FROM THE PACIFIC NORTHWEST TOWARD THE SOUTHWEST STATES. STRONG
WINDS OF 20 TO 30 MPH WITH GUSTS OVER 40 MPH WILL BE LIKELY DURING
THE LATE MORNING THROUGH EVENING HOURS WEDNESDAY. THIS MAY RESULT IN
AREAS OF BLOWING SAND AND DUST DEVELOPING. IN COMBINATION WITH VERY
