.SYNOPSIS...
STRONG GUSTY WINDS WITH AREAS OF BLOWING DUST IS THE FORECAST FOR
INTO THIS EVENING AHEAD OF A PACIFIC COLD FRONT. LOCALIZED DENSE
BLOWING DUST WITH SHARPLY REDUCE VISIBILITY IS ALSO EXPECTED. THE
STRONG PACIFIC COLD FRONT WITH A CHANCE OF SHOWERS AND THUNDERSTORMS
WILL MOVE EAST ACROSS SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA
THROUGH THIS EVENING WITH SHOWERS LIKELY AND A CHANCE OF THUNDER-
STORMS IN SOUTH-CENTRAL ARIZONA INCLUDING THE PHOENIX AREA BY LATE
THIS EVENING AND TONIGHT. IT WILL BE MUCH COLDER SATURDAY WITH NEAR
RECORD COOL DESERT HIGHS BETWEEN 60 AND 70 DEGREES. A FEW SHOWERS
ARE POSSIBLE AGAIN LATE SUNDAY INTO MONDAY WITH ANOTHER COLD FRONT.
WARMER WEATHER MAY FINALLY RETURN TOWARD THE END OF NEXT WEEK.

&&

.DISCUSSION...
...PACIFIC STORM SYSTEM WITH STRONG WINDS...BLOWING DUST...SHOWERS...
POSSIBLE THUNDERSTORMS...AND MUCH COOLER WEATHER...

VIGOROUS PACIFIC TROF STILL PUSHING STEADILY EASTWARD AND INLAND
EARLY THIS EVENING WITH THE TROF AXIS RUNNING FROM CENTRAL NV
SOUTHWARD THRU FAR SERN CA. MAIN VORT MAX APPEARED TO BE APPROACHING
YUMA FROM THE SOUTHWEST AT 8 PM PER THE VAPOR IMAGERY. SYSTEM
APPEARS TO BE BOTH VERY DYNAMIC AND REASONABLY MOIST. LATEST SAN
DIEGO SOUNDING SHOWED A SATURATED MARINE LATER TO ABOUT 650 MB AND
IR IMAGERY SHOWED SIGNIFICANT LOW CLOUDS/STRATUS MOVING INLAND OVER
THE COASTAL RANGES AND INTO OUR CWA ASSOCIATED WITH THE FRONTAL
BAND. FRONTAL BAND NOW MOVING EAST ACROSS THE SOUTHEAST AZ DESERTS
WITH NUMEROUS SHOWERS ON RADAR SPREADING EAST OF THE LOWER CO RIVER
VALLEY.

SYSTEM AND ASSOCIATED FRONT APPEAR TO BE A FEW HOURS SLOWER THAN
PREVIOUSLY THOUGHT...AND THE COLD FRONT WILL PROBABLY NOT GET INTO
THE PHOENIX AREA TIL BETWEEN 10 AND 11 PM THIS EVENING. RAISED POPS
A BIT FOR TONIGHT ACROSS ARIZONA...WITH LIKELY NUMBERS OVER SWRN AZ
AND CATEGORICAL VALUES FROM MARICOPA COUNTY EASTWARD. MOST OF THE
COLD AIR ALOFT APPEARS FOCUSED OVER NORTHERN ARIZONA...BUT THE
DIFLUENCE ALOFT/PVA/DYNAMICS ARE HELPING TO FORCE A FEW STORMS OVER
THE HIGHER TERRAIN NORTH AND EAST OF PHOENIX. ALREADY HAVE SEEN A
FEW LIGHTNING STRIKES OVER SRN GILA COUNTY...AND THERE WILL BE A
SLIGHT CHANCE FOR THUNDERSTORMS LATER THIS EVENING OVER THE CENTRAL
DESERTS AS THE COLD FRONT MOVES THRU THE AREA. EXPECT TO SEE GUSTY
WINDS AHEAD OF AND ASSOCIATED WITH THE FRONT...THAT IS WHY THE WIND
ADVISORY FOR SOUTH CENTRAL AZ CONTINUES DESPITE MOST WIND REPORTS
CURRENTLY BELOW THRESHOLDS. FORECASTS HAVE BEEN UPDATED TO REFLECT
THE CURRENT SKY POP AND WEATHER TRENDS AND LOOK TO BE IN GOOD SHAPE.

.PREVIOUS DISCUSSION...
AREAS OF BLOWING DUST WERE DEVELOPING IN THE GENERAL AREA BETWEEN
CASA GRANDE...THE PHOENIX AREA...AND GILA BEND EARLY THIS AFTERNOON.
WIND WAS FROM THE SOUTH AND SOUTHWEST GUSTING BETWEEN 30 AND 40 MPH
IN THIS AREA. WIND WAS GENERALLY FROM THE SOUTHWEST AND WEST GUSTING
BETWEEN 25 AND 35 MPH IN SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA.

CLOUDINESS FROM THE SOUTHWEST WAS GRADUALLY INCREASING ACROSS THE
AREA THIS AFTERNOON. TEMPERATURES WERE GENERALLY UP TO 5 DEGREES
WARMER IN PORTIONS OF SOUTH-CENTRAL ARIZONA...AND AT LEAST A FEW
DEGREES COOLER IN FAR SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA
EARLY THIS AFTERNOON COMPARED WITH THE SAME TIME YESTERDAY. DEW
POINT TEMPERATURES WERE GENERALLY 20 TO 30 DEGREES HIGHER SOUTHWEST
AND WEST OF PHOENIX AND 3 TO 15 DEGREES HIGHER FROM PHOENIX EASTWARD.

A PACIFIC COLD FRONT WITH MOSTLY LIGHT SHOWERS WAS SWINGING EAST
INTO SOUTHEAST CALIFORNIA THIS AFTERNOON. RIGHT BEHIND THE
FRONT...THE MAIN LOW PRESSURE SYSTEM WITH MOST OF THE SHOWERS AND
ISOLATED THUNDERSTORMS WAS SWINGING EAST OVER SOUTHERN
CALIFORNIA.

WINDS FROM THE SOUTH AND WEST ARE EXPECTED TO INCREASE SOMEWHAT MORE
ACROSS SOUTHEAST CALIFORNIA...AND SOUTHWEST AND SOUTH-CENTRAL
ARIZONA INTO THIS EVENING AS THE STRONG PACIFIC COLD FRONT
APPROACHES FROM THE WEST. STRONG CROSS WINDS ARE EXPECTED ACROSS
SOME ROADS AND HIGHWAYS. THE STRONGEST WINDS ARE EXPECTED IN
SOUTHWEST AND SOUTH-CENTRAL ARIZONA WITH GUSTS TO OVER 40 AND
POSSIBLY 50 MPH INTO THIS EVENING.

THE STRONG GUSTY WINDS ARE EXPECTED TO CONTINUE TO CAUSE AREAS OF
BLOWING DUST IN THE DESERT AREAS. THIS INCLUDES INTERSTATES 10 AND 8
BETWEEN TUCSON...CASA GRANDE...PHOENIX...GILA BEND...YUMA...AND EL
CENTRO. THE AREA BETWEEN TUCSON...CASA GRANDE...PHOENIX...AND GILA
BEND IS ESPECIALLY PRONE TO LOCALIZED VERY DENSE BLOWING DUST WITH
NEAR ZERO VISIBILITY POSSIBLE INTO THIS EVENING. THE BLOWING DUST
COULD BE A CONCERN FOR THE LATE AFTERNOON COMMUTER RUSH HOUR IN THE
GREATER PHOENIX AREA.

THE STRONG PACIFIC LOW PRESSURE SYSTEM AND COLD FRONT WITH STRONG
DYNAMICS WILL ACCELERATE EAST AND RESULT IN A CHANCE OF SHOWERS AND
THUNDERSTORMS THAT WILL MOVE FROM WEST TO EAST ACROSS SOUTHEAST
CALIFORNIA AND SOUTHWEST ARIZONA INTO THIS EVENING...THEN SHOWERS
ARE LIKELY IN SOUTH-CENTRAL ARIZONA BY LATE THIS EVENING AND DURING
THE NIGHT ALONG WITH AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS.

MOST OF THE RAIN IS EXPECTED TO BE IN SOUTH-CENTRAL ARIZONA INCLUDING
THE GREATER PHOENIX AREA TONIGHT. MOST OF THE SHOWERS AND CHANCE OF
THUNDERSTORMS WILL PROBABLY NOT REACH THE PHOENIX AREA UNTIL LATE
THIS EVENING.

RAINFALL AMOUNTS ARE EXPECTED TO BE LESS THAN A TENTH OF AN INCH IN
SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING EL CENTRO AND
YUMA. RAINFALL AMOUNTS ARE EXPECTED TO RANGE FROM 1 TENTH OF AN INCH
TO MORE THAN A QUARTER OF AN INCH IN THE SOUTH-CENTRAL ARIZONA
DESERT INCLUDING THE PHOENIX AREA TO MORE THAN A THIRD OF AN INCH
IN THE HIGHER TERRAIN NORTH AND EAST OF THE GREATER PHOENIX AREA.

COLDER AIR WILL MOVE IN BEHIND THE FRONT WITH WELL BELOW AVERAGE
TEMPERATURES. COMPARED WITH TODAY...HIGH TEMPERATURES ARE EXPECTED
TO BE 10 TO 20 DEGREES COLDER SATURDAY WITH HIGHS BETWEEN 60 AND 70
IN THE DESERT AREAS INCLUDING PHOENIX...YUMA AND EL CENTRO. AND...
DESERT LOW TEMPERATURES ARE EXPECTED TO BE IN THE MID 30S TO UPPER
40S SATURDAY NIGHT.

THE SNOW LEVEL WILL LOWER TO BETWEEN 5 THOUSAND AND 55 HUNDRED FEET
BY SATURDAY MORNING. HOWEVER...MOST OF THE PRECIPITATION WILL HAVE
ENDED BY THEN. THUS...NO SIGNIFICANT SNOWFALL ACCUMULATION IS
EXPECTED AT THAT LEVEL.

PREVIOUS DISCUSSION...
GOOD AGREEMENT NOW THAT WE/LL SEE ANOTHER LOW PRESSURE SYSTEM SWING
THROUGH THE SOUTHWEST SUNDAY INTO MONDAY. POPS WERE INCREASED ONCE
AGAIN FOR THIS SYSTEM...EVEN THOUGH IT IS NOT AS STRONG AS TODAY/S
STORM THE BOUNDARY LAYER WILL STILL BE SUFFICIENTLY MOIST THAT AN
EXTENDED PERIOD OF WETTING UP WON/T BE NEEDED. THIS SECOND SYSTEM
WILL ALSO BRING ANOTHER PUSH OF COOLER AIR FOR MONDAY/TUESDAY.

FORECAST FOR TUESDAY THROUGH FRIDAY OF NEXT WEEK GETS MURKY.
STARTING TO SEE MORE EVIDENCE OF A MORE SUBSTANTIAL RIDGE DEVELOPING
OVER THE WEST COAST AS A LARGE CUT-OFF LOW DEVELOPS WEST OF THE
NORTHERN CALIFORNIA COAST. HOWEVER...THERE IS A LOT OF SPREAD IN THE
MODEL DATA LEADING TO BELOW AVERAGE CERTAINTY. FOR NOW WILL GO WITH
THE MEAN SOLUTION OF RIDGING OVERHEAD WHICH WILL BRING TEMPERATURES
BACK CLOSE TO NORMAL.
