AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
230 AM MST TUE AUG 1 2006
SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA
FORECAST DISCUSSION
.SYNOPSIS...
VERY HUMID AIR OVER OUR AREA MEANS THAT THE CHANCE OF SHOWERS AND
THUNDERSTORMS WILL CONTINUE MAINLY IN SOUTH-CENTRAL ARIZONA INCLUDING
THE GREATER PHOENIX AREA THROUGH TONIGHT. A SOUTHWESTERLY FLOW OF
AIR ALOFT WILL BRING DRIER WEATHER TO SOUTHEAST CALIFORNIA AND FAR
SOUTHWEST ARIZONA THIS WEEK...MOSTLY CLEAR NIGHTS AND SUNNY AND
WARMER DAYS EXPECTED. A MORE SOUTHERLY FLOW ALOFT OVER SOUTH-CENTRAL
ARIZONA WILL KEEP ENOUGH MOISTURE IN THE AREA WEDNESDAY THROUGH THE
WEEKEND FOR A SLIGHT CHANCE FOR AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS...WITH THE GREATEST CHANCES OVER THE HIGHER TERRAIN
EAST OF PHOENIX.
&&
.SHORT TERM...
TODAY THROUGH THURSDAY...
LOW PRESSURE TROF DEVELOPING ALONG THE CA COAST HAS SET UP A SWLY
WINDFLOW OVER MOST OF OUR CWA...AND IS SERVING TO GRADUALLY DRY OUT
THE AIRMASS FROM THE WEST. RECENT GOES PWAT IMAGERY SHOWED VALUES
BELOW ONE INCH OVER MOST OF OUR CA ZONES...AND SURFACE DEWPOINTS OUT
WEST HAD DROPPED INTO THE MID 50S TO LOW 60S. HIGH MOISTURE REMAINS
YET OVER OUR ERN ZONES...WITH 1.92 INCHES PWAT DEPICTED ON THE
RECENT 03Z PSR SOUNDING...AND SURFACE DEWPOINTS OVER THE CENTRAL
DESERTS WERE IN THE MID 60S TO LOW 70S. AT 2 AM A FEW SHOWERS AND
STORMS WERE MOVING ACROSS ZONE 24...UNDER PARTLY TO MOSTLY CLOUDY
SKIES. IR IMAGERY SHOWED MOSTLY CLEAR SKIES OUT WEST WITH SOME MID
TO HIGH CLOUDINESS LOOKING TO GRADUALLY SPREAD OVER THE AREA FROM
THE SOUTH.
STEERING FLOW TODAY SHOULD BE BASICALLY WESTERLY OVER MOST OF OUR
CWA...WHICH IS NOT A FAVORABLE DIRECTION...BUT GIVEN THE MOISTURE
AND DYNAMICS ASSOCIATED WITH THE WESTERLIES CLOSE BY...WILL KEEP A
SLIGHT CHANCE FOR SHOWERS AND STORMS GOING ALL DAY AND THRU TONIGHT
IN OUR SOUTH-CENTRAL ZONES...WITH ABOUT A 20 PERCENT POP FOR
PHOENIX. EXPECT SUNNY OR MOSTLY SUNNY SKIES OUT WEST. FOR THE NEXT
COUPLE OF DAYS THE TROF REMAINS IN PLACE TO OUR WEST BUT IT DOES NOT
MOVE BODILY INLAND FAR ENOUGH TO REALLY DRY OUT OUR ERN CWA. BOTH
THE GFS AND NAM FORECAST 12-14C 850MB DEWPOINTS EAST OF THE LOWER CO
RIVER WEDNESDAY IN FACT...THO FORCING IS WEAK AND STEERING FLOW
REMAINS SWLY. BY THURSDAY FLOW ACTUALLY STARTS BACKING AS THE TROF
SHARPENS UP SLIGHTLY OFF THE CA COAST...AND MOISTURE STARTS WORKING
BACK WESTWARD. AS A RESULT WILL UP OUR POPS WED AND THURSDAY AND
KEEP SLIGHT CHANCES GOING OVER THE SOUTH-CENTRAL DESERTS INCLUDING
THE PHOENIX AREA BOTH DAYS...WITH CHANCE POPS OVER THE HIGHER
TERRAIN TO OUR EAST. SWLY FLOW WILL ONLY BE GOOD ENOUGH TO REMOVE
THE POPS FROM OUR CA ZONES AND THE FAR WESTERN DESERTS. WITH
MOISTURE DECREASING AND MORE SUNSHINE AVAILABLE TEMPS WILL START TO
RISE...BUT SHOULD STILL REMAIN BELOW SEASONAL NORMALS THROUGH
THURSDAY.
DUE TO RECENT HEAVY RAINS...THE FLOOD WARNING FOR RISING WATERS ON
THE SAN CARLOS RIVER CONTINUES UNTIL 530 AM THIS MORNING. ALSO A
FLASH FLOOD WATCH FOR THE LOWER TONTO CREEK REMAINS IN EFFECT
THROUGH 11 AM TODAY.
&&
.LONG TERM...
THURSDAY NIGHT THROUGH MONDAY...
A DRIER FLOW OF AIR FROM THE SOUTHWEST...AHEAD OF A DEVELOPING LOW
PRESSURE SYSTEM NEAR THE WEST COAST...WILL BRING DRIER WEATHER AND
SOMEWHAT WARMER DAYS TO THE ENTIRE AREA THROUGH THE END OF THIS
WEEK. THE ONLY EXCEPTION WILL BE A SLIGHT CHANCE OF AFTERNOON AND
EVENING SHOWERS AND THUNDERSTORMS OVER THE HIGHER TERRAIN EAST OF
THE GREATER PHOENIX AREA WHERE ENOUGH HUMID AIR MAY CONTINUE.
HOWEVER...ENOUGH DRIER AIR WILL PROBABLY MOVE INTO THAT AREA AT
LEAST THURSDAY AND FRIDAY FOR MOSTLY CLEAR SKIES.
THE WEST COAST LOW PRESSURE SYSTEM IS EXPECTED TO WEAKEN AND HIGH
PRESSURE ALOFT OVER THE GULF COAST STATES IS EXPECTED TO EXPAND WEST
WITH SOME HUMID AIR RETURNING FROM THE SOUTHEAST AT LEAST TO
SOUTH-CENTRAL ARIZONA NEXT WEEK. THIS MEANS A SLIGHT CHANCE OF
MAINLY LATE AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
RETURNING TO ALL OF SOUTH-CENTRAL ARIZONA INCLUDING THE GREATER
PHOENIX AREA NEXT WEEK.
