AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
955 AM MST TUE APR 29 2008

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

.SYNOPSIS...
WARM AND DRY WEATHER WILL CONTINUE TODAY...BEFORE A VERY DRY LOW
PRESSURE SYSTEM BRINGS BREEZY TO WINDY CONDITIONS WEDNESDAY...AND
COOLER TEMPERATURES THROUGH THE LATTER PART OF THE WEEK. EXPECT LESS
WIND AND WARMER WEATHER FRIDAY...FOLLOWED BY YET ANOTHER WEATHER
SYSTEM LATE IN THE UPCOMING WEEKEND.

&&

.DISCUSSION...
UPPER AIR DATA FROM 12Z INDICATED THE DEEP TROUGH WAS JUST ABOUT ON
THE WEST COAST AT THAT TIME. NOT MUCH MOISTURE WITH THIS SYSTEM
ACROSS OUR PART OF THE SOUTHWESTERN STATES...BUT THE LAST IMPULSE
HAD JUST ENOUGH RH TO TRIGGER SOME HIGH-BASED CONVECTIVE CLOUDS IN
NORTHERN AZ. ONE PIREP INDICATED SOME CB ACTIVITY EAST OF KIGM.

THE OTHER CONCERN WITH THIS IMPULSE IS THE MODERATE WINDS ALOFT NOW
ACROSS OUR CWA. AT 500MB WE HAD ONLY 30-40 KTS...AND UPSTREAM FLOW
IS NOT ALL THAT SIGNIFICANT. WE HAVE ADJUSTED THE SHORT TERM WINDS
DOWNWARD...AND THE GUSTY WINDS FOR LATER TODAY DO NOT APPEAR TO BE
DEVELOPING ACROSS OUR AREA. FOR WEDNESDAY...MODELS SHOW A FURTHER
TIGHTENING OF THE GRADIENT AND OUR WINDS WILL PICK UP EVEN MORE.
WIND SPEEDS APPEAR TO STAY BELOW WIND ADV THRESHOLDS ON WED.

THAT SYSTEM WILL ALSO BRING A COOLING TREND...AND MAX TEMPS FOR WED
AND THURSDAY WILL BE DOWN CONSIDERABLY. IN FACT LATEST GFS SHOWS
ABOUT 100 METER HEIGHT FALLS AT 500MB BY WED NIGHT/THURSDAY MORNING.

BY LATE IN THE WEEKEND...ANOTHER STRONG PACIFIC STORM SYSTEM WILL
FORM NEAR THE WEST COAST AND MOVE ACROSS AZ. THIS ONE WILL AGAIN
BRING ADDITIONAL MOISTURE AT THE HIGHER LEVELS...INCREASING
WINDS...AND LOWER DAYTIME TEMPS. LATEST GFS MOS SHOWS 92 FOR PHOENIX
BOTH SUNDAY AND MONDAY AS THE TROUGH BOTTOMS OUT IN SOUTHERN AZ.

&&

.AVIATION...
WRN TAF SITES...WINDS TO START OUT RATHER LIGHT WITH NORMAL MORNING
TENDENCIES BEFORE BREEZES BEGIN TO PICK UP LATER THIS AFTERNOON IN
ADVANCE OF A STRONG PACIFIC WEATHER SYSTEM. STRONGEST WINDS AFT 21Z
WILL BE NOTED ESPECIALLY AT KBLH/KIPL WHERE GUSTS NEARING 30KTS PSBL
22Z-02Z. COULD BE SOME PATCHY AREAS OF BLOWING DUST AND SAND...BUT
NOT CERTAIN ENOUGH OF THIS TO INCLUDE AS TEMPO GROUPS ATTM. WINDS
WILL BEGIN TO TAPER OFF LATE THIS EVENING...WITH ANOTHER WINDY DAY
ON TAP OUT W FOR WEDNESDAY.

OVER KPHX/KIWA TAF SITES...EXPECT SOMEWHAT LESS WIND BY LATE
AFTERNOON THAN OUR WRN NEIGHBORS...BUT STILL POSSIBLY GUSTING TO
20KTS AFT 22Z. NORMAL LIGHT...NOCTURNAL WINDS ANTICIPATED AT BOTH
SITES LATE TONIGHT...IE MAINLY FROM THE SOUTHEAST OR E. WINDIER WX
ON TAP FOR WEDNESDAY AT BOTH TAF SITES...WITH SOME WLY GUSTS TO
25KTS POSSIBLE.

ONLY SOME PATCHY CIRRUS CLOUDINESS AT ALL TAF SITES NEXT 24 HRS.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
WINDS ARE EXPECTED TO INCREASE IN SOUTHEAST CALIFORNIA AND THE LOWER
COLORADO RIVER VALLEY TODAY AS A PACIFIC LOW PRESSURE SYSTEM
APPROACHES THE SOUTHWEST US. SUSTAINED SPEEDS UP TO 20 MPH WILL BE
POSSIBLE IN IMPERIAL AND RIVERSIDE COUNTIES...WITH A FEW GUSTS UP TO
35 MPH POSSIBLE. RH VALUES WILL BE WELL UNDER 15 PERCENT DURING THE
DAY. CONDITIONS MAY BRIEFLY APPROACH CRITICAL FIRE WEATHER
CONDITIONS IN THE LATE AFTERNOON INTO EARLY EVENING HOURS.

THE STRONGEST WINDS WILL SHIFT EASTWARD WEDNESDAY INTO THE LOWER
COLORADO VALLEY AND SOUTHWEST/SOUTH-CENTRAL ARIZONA. EXPECT
SUSTAINED WIND SPEEDS OF 20-25 MPH/GUSTS 35-40 MPH TO DEVELOP IN THE
LATE MORNING HOURS AND PERSIST THROUGH THE EARLY EVENING. THIS
COMBINED WITH VERY DRY AIR WILL CREATE HAZARDOUS FIRE WEATHER
CONDITIONS...AND MANY LOCATIONS ALONG THE LOWER COLORADO RIVER
VALLEY...AS WELL AS SOUTHWEST AND SOUTH-CENTRAL ARIZONA...WILL
EXCEED CRITICAL FIRE WEATHER CONDITIONS BY WEDNESDAY NOON. THUS...
FIRE WEATHER WATCH WILL CONTINUE FROM 11 AM UNTIL 8 PM
WEDNESDAY.

THURSDAY THROUGH THE WEEKEND...LIGHTER WINDS ANTICIPATED THROUGH THE
END OF THE WEEKEND AS DRY AIR WILL REMAIN OVER THE SOUTHWEST US.
ANOTHER LOW PRESSURE SYSTEM MAY AFFECT THE REGION SUNDAY...LEADING
TO BREEZY CONDITIONS.
