AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
921 AM MST TUE MAY 17 2011

.SYNOPSIS...
LOW PRESSURE WILL APPROACH THE REGION TODAY AND WINDS WILL INCREASE
THROUGH THIS EVENING. VERY WINDY WEATHER IS LIKELY TO SPREAD INTO
ALL AREAS ON WEDNESDAY...ALONG WITH A CHANCE OF SHOWERS FOR SOUTH
CENTRAL ARIZONA. HIGH TEMPERATURES ARE FORECAST TO BE IN THE 70S AND
80S THE REST OF THE WEEK BEFORE DRIER AND WARMER WEATHER ARRIVES ON
SATURDAY. ANOTHER PACIFIC LOW PRESSURE SYSTEM WILL MOVE IN SUNDAY
AND MONDAY.

&&

.DISCUSSION...
MID MORNING SATELLITE IMAGERY REVEALS A DEPARTING SHORTWAVE TROUGH
ACROSS EASTERN ARIZONA...WITH ANOTHER DEEPENING TROUGH ACROSS
NORTHERN CALIFORNIA. CLOUDS WERE THIN BUT INCREASING ACROSS THE
REGION THIS MORNING AS A 100KT JET STREAK MOVED ONSHORE ACROSS
SOUTHERN CALIFORNIA. AT THE SURFACE...WINDS WERE INCREASING ACROSS
SOUTHEASTERN CALIFORNIA ALONG WITH DEWPOINTS WHILE WINDS REMAINED
LIGHT AND DEWPOINTS REMAINED LOW EAST OF THE COLORADO RIVER.

FOR THE REST OF TODAY...VARYING AMOUNTS OF HIGH CLOUD COVER ARE
EXPECTED BUT IN GENERAL IT WILL BE A MOSTLY SUNNY/PARTLY CLOUDY DAY.
I MADE MINOR ADJUSTMENTS TO CLOUD COVER FOR TODAY AND TONIGHT AS I
DONT THINK THE EXTENSIVE AREA OF CLOUD COVER WILL ARRIVE UNTIL SOME
TIME ON WEDNESDAY AS THE MAIN SHORTWAVE TROUGH MOVES THROUGH
NORTHERN ARIZONA.

I ALSO REFINED THE POPS TO REMOVE ALL MENTION /ASIDE FROM FAR
SOUTHWEST IMPERIAL COUNTY/ OF PRECIP TODAY AND TONIGHT. INCOMING 12Z
MODEL DATA SUGGESTS THAT THE BOUNDARY LAYER WILL REMAIN TOO DRY FOR
PRECIP TODAY AND TONIGHT. BEST CHANCE OF PRECIP WILL BE WEDNESDAY
AFTERNOON INTO WEDNESDAY EVENING...THIS IS ALREADY REFLECTED WELL IN
THE FORECAST AND ONLY MINOR ADJUSTMENTS WILL BE MADE LATER THIS
AFTERNOON. OTHERWISE THE FORECAST REMAINS ON TRACK.

&&

.PREVIOUS DISCUSSION...
AS THE NEXT IMPULSE ROTATES INTO THE WESTERN STATES...OUR AREA WILL
SEE THE WINDY AND COOLER CONDITIONS...PARTICULARLY IN THE WESTERN
HALF OF THE CWA. LATEST MOS GUIDANCE CALLS FOR STRONG WINDS AND
HIGHS ONLY IN THE 70S AND LOWER 80S FOR BLYTHE AND IMPERIAL. GFS AND
ECMWF BOTH SHOW THE DEEP LOW HUGGING THE CALIF/OREGON COAST
TONIGHT...AND THEN MOVING INLAND AND NEAR THE UTAH/ARIZONA BORDER BY
LATE WEDNESDAY. ASSOCIATED LOW LEVEL GRADIENT TIGHTENS UP MORE ON
WEDNESDAY...AND 925 MB WINDS GENERALLY RUN 10 KTS STRONGER WEDNESDAY
COMPARED TO TODAY. WILL HOLD OFF ON THE WIND ADVISORY FOR
TODAY...ALTHOUGH THERE MAY BE PATCHY AREAS OF BLOWING DUST WEST OF
THE LOWER COLORADO RIVER VALLEY.

BY LATE WEDNESDAY AND INTO THURSDAY...STRONGER FORCING AND DEEPER
MOIST LAYER ARRIVES INTO SOUTH CENTRAL AZ. BEST CHANCE OF SHOWERS IN
PHOENIX WILL BE WED NIGHT...ALTHOUGH HIGHER POPS STILL IN ORDER
ACROSS SOUTHERN GILA. DONT EXPECT ANY HEAVY RAIN WITH THIS DEEP LOW
TO OUR NORTH. WE AGREE WITH LATEST HPC OUTPUT AND WILL SHOW PHOENIX
GETTING ENOUGH RAIN TO SETTLE THE DUST...AND ONLY ABOUT A TENTH OF
AN INCH OR SO IN THE HIGHER ELEVATIONS OF ZONE 24.

TEMPERATURES WILL ONLY WARM TO THE UPPER 60S IN GLOBE/MIAMI
WEDNESDAY AND THURSDAY...AND ONLY IN THE UPPER 70S IN PHOENIX. THE
RECORD LOWEST HIGH TEMP IN PHOENIX ON WEDNESDAY IS 75F. MODELS STILL
SHOW A SHORT-LIVED RIDGE PASSING THROUGH ARIZONA FRIDAY NIGHT AND
SATURDAY...FOR A NICE WEEKEND WITH BELOW NORMAL TEMPS.

NEXT TROUGH WILL DIVE SOUTH ALONG THE COAST...AND BOTH GFS AND ECMWF
SHOW IDENTICAL DEVELOPMENT AND SPEED. THUS WE HAVE GOOD CONFIDENCE
ON KEEPING PRECIP IN FORECASTS FOR THE NORTHERN PARTS OF OUR CWA
SUNDAY NIGHT INTO EARLY MONDAY.

&&

.AVIATION...
SOUTH-CENTRAL...INCLUDING KPHX AND KIWA...
THROUGH 19Z TUE...BKN CLDS AOA 20 THSD MSL...SOUTHWEST WIND 5 TO 15
KTS. BETWEEN 19Z TUE AND 04Z WED...INCREASING WEST WINDS 15 TO 25
