AZZ020>028-CAZ030>033-271045- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 915 PM MON JUL 26 2004 SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... MOISTURE WILL CONTINUE OVER THE AREA WITH A POSSIBILITY OF SHOWERS AND THUNDERSTORMS TONIGHT. BY TUESDAY NORTHWESTERLY FLOW FROM A HIGH PRESSURE AREA NEAR THE SOUTHERN CALIFORNIA COAST WILL SPREAD DRIER AIR FROM THE NORTHWEST IN OUR REGION. THIS WILL CONFINE A SLIGHT CHANCE OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS TO THE HIGHER TERRAIN EAST OF THE GREATER PHOENIX AREA BY WEDNESDAY. THE DRY WEATHER IS EXPECTED OVER THE ENTIRE AREA BY THURSDAY AND FRIDAY. THIS HIGH PRESSURE CENTER WILL MOVE EAST TO NEW MEXICO BY THE WEEKEND...HELPING TO BRING A RETURN OF MOISTURE AND A SLIGHT CHANCE OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS BACK TO SOUTH CENTRAL ARIZONA. && .DISCUSSION... PLENTY OF MOISTURE AVAILABLE FOR CONVECTION ACROSS AZ TODAY...WITH GOES PWAT IMAGERY SHOWING A PLUME OF UP TO 1.5 INCHES EXTENDING UP OVER MOST OF SRN AZ THIS EVE...AND THE 00Z PSR RAOB SHOWED 1.33 INCHES. SURFACE DEWPOINTS OVER THE AZ DESERTS STILL A BIT ON THE SKIMPY SIDE THO...RUNNING MAINLY IN THE MID TO UPPER 50S AS OF 8 PM THIS EVENING. UPPER HIGH NOW SITUATED OFF THE SRN CA COAST...WITH A NWLY STEERING FLOW IN EFFECT OVER MOST OF THE CWA...AS SEEN IN THE WATER VAPOR IMAGERY AS WELL AS THE VAD WIND PROFILE DATA AND EVE SOUNDINGS. FOR THE MOST PART THIS AFTERNOON AND EVE...STORMS HAVE FORMED OVER CENTRAL AZ...NORTH OF OUR NRN CWA BORDER...THEN DRIFTED TO THE SE AND MAINLY AFFECTED THE AREA NORTH AND EAST OF PHOENIX ...WITH ZONE 24 SEEING MOST OF THE STORMS. RATHER STRONG CONVECTION THAT DEVELOPED OVER SRN YAVAPAI COUNTY AND MOVED INTO FAR NRN ZONE 23 SENT STRONG OUTFLOW TO THE SOUTHWEST THAT RANGED FROM 20 TO 40 MPH IN PLACES. FOR THE MOST PART AS THE OUTFLOW MOVED SOUTH AND WEST NO NEW STORMS WERE TRIGGERED...AS THE AIRMASS OVER THE CENTRAL DESERTS STILL A BIT MOISTURE STARVED. IF THOSE BOUNDARIES COMING FROM THE NORTH HAD MET OTHER OUTFLOW COMING FROM THE SOUTHEAST THEN STRONG STORMS MIGHT HAVE FIRED UP OVER THE PHOENIX AREA...BUT WE HAVE NOT SEEN THOSE BOUNDARIES MOVING FROM THE SE AS CONVECTION HAS BEEN LIMITED THERE TODAY. TONIGHT MAY BE SOMEWHAT OF A REPEAT PERFORMANCE FROM WHAT HAPPENED LAST NIGHT...AS A CLUSTER OF STORMS CONTINUED TO DEVELOP OVER SRN YAVAPAI COUNTY AS OF 9 PM...WITH THE DEVELOPMENT MORE AND MORE TO THE WEST OVER THE PAST FEW HOURS. WITH THE STEERING FLOW FROM THE NW...THIS MEANS A BETTER CHANCE FOR THOSE STORMS TO MOVE INTO CENTRAL MARICOPA COUNTY AND THE PHOENIX METRO AS THE NIGHT WEARS ON...AND THERE COULD BE MORE STORMS AND SHOWERS IN THE AREA AT AND AFTER MIDNIGHT. THERE APPEARS TO BE ANOTHER SHORT WAVE MOVING AROUND THE HIGH AND THRU NRN AND CENTRAL AZ TONIGHT...AND THIS CAN BE SEEN IN THE PLOT DATA AS WELL AS THE VAPOR IMAGERY...WHERE SIGNIFICANT DIFLUENCE ASSOCD WITH THE UPPER SHORT WAVE IS NOTED OVER CENTRAL AZ. ETA FORECASTS THIS SHORT WAVE TO MOVE TO THE SE TONIGHT...AND THIS WILL ADD DYNAMICS TO THE MIX AND ALLOW THE STORMS TO MAINTAIN SOME ORGANIZATION FOR SOME HOURS TO COME. SOME CHANGES TO THE FORECAST FOR TONIGHT MAY BE MADE TO REFLECT THE INCREASED CHANCE FOR STORMS TO CONTINUE PAST MIDNIGHT OVER OUR ERN CWA. OTHERWISE FORECAST LOOK OK...BASIC TRENDS ARE FINE. AS WE HEAD INTO THE MIDDLE OF THE WEEK...FLOW BECOMES INCREASINGLY WESTERLY OR NORTHWESTERLY AND THIS SPREADS DRIER AIR INTO OUR CWA FROM THE WEST. IOP FOR INCREASED RAOBS FOR NAME PROJECT...MONSOON SUPPRESSION 00Z WED TO 00Z FRI. .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE. CA...NONE. && 11
