AZZ020>028-CAZ030>033-041200- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 900 PM MST SUN SEP 3 2006 SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... SUBTROPICAL MOISTURE WILL INCREASE OVER THE REGION THROUGH LABOR DAY AS TROPICAL STORM JOHN...CURRENTLY OVER THE SOUTH-CENTRAL BAJA CALIFORNIA PENINSULA...WEAKENS TO TROPICAL DEPRESSION STATUS AND MOVES SLOWLY TOWARD THE NORTHWEST. SHOWERS AND THUNDERSTORMS... WITH LOCALLY HEAVY RAIN...WILL BE POSSIBLE AT ANY TIME THROUGH TUESDAY. LINGERING MOISTURE WILL REMAIN OVER OUR REGION THROUGHOUT THE REMAINDER OF THE UPCOMING WEEK...FOR A CONTINUED CHANCE OF MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. && .SHORT TERM... TONIGHT THROUGH WEDNESDAY... MODELS AREA HAVING A TERRIBLE TIME FORECASTING MOISTURE INTRUSIONS INTO ARIZONA FROM OLD HURRICANE JOHN...AND FORECASTING THE KINEMATICS AND SUBTLE DYNAMICS AT ALL LEVELS. PERHAPS THIS IS DUE TO ABSOLUTELY NO MEXICAN UPPER AIR DATA FOR THE PAST 24 HOURS...AND FROM NCEPS DISCUSSION...NO MORE NOAA HURRICANE HUNTER DROPSONDE DATA SINCE JOHN BECAME A TROPICAL DEPRESSION. SO THE REMNANTS OF JOHN LOCATED OVER CENTRAL BAJA ARE SPINNING DOWN IN A DATA SPARSE AREA. AND...THIS DATA SPARSE AREA AGAIN HAS RESULTED IN VARYING AND BAD MODEL FORECASTS...INCLUDING WHAT HAPPENED SUNDAY AFTERNOON AND EVENING. IT TURNED OUT THAT UPPER LEVEL WESTERLY PACIFIC FLOW ACROSS SOUTHERN CA...MERGING WITH SOUTHWESTERLY FLOW OUT OF BAJA...RESULTED IN STRONG UPPER LEVEL CONVERGENCE AND NEARLY CLEAR SKIES OVER SOUTHWEST AND SOUTH CENTRAL AZ. UPPER LEVEL CONVERGENCE WAS STRONG ENOUGH TO PRODUCE ONLY ISOLATED LOW TOPPED THUNDERSTORMS ALONG THE MOGOLLON RIM. AGAIN...REMNANTS OF JOHN WERE SPINNING IN A DATA SPARSE AREA...AND MODEL FORECASTS GOING FORWARD THEREFORE CAN BE UNCERTAIN AT BEST. THE COLORADO STATE ENSEMBLE TRAJECTORY FORECASTS...BASICALLY STALL TROPICAL DEPRESSION JOHN OVER CENTRAL BAJA. HOWEVER THE GFS MODEL FORECASTS ITS DYING CIRCULATION TO MOVE TO A POINT 88 MILES SOUTHEAST OF YUMA...ALONG THE MEXICAN BORDER BY MONDAY EVENING. ALSO THE GFS FORECASTS A WEAK UPPER LEVEL DISTURBANCE TO MOVE OVER SOUTHWEST AND SOUTH CENTRAL AZ MONDAY AFTERNOON TO PROVIDE A LITTLE SUPPORT. GENERALLY HOWEVER...THE MODELS ARE FORECASTING AN UPSWING IN CONVECTIVE ACTIVITY MONDAY AFTERNOON AND EVENING ACROSS PORTIONS OF SOUTHWEST AND SOUTH CENTRAL AZ. ULTIMATELY THEREFORE...WE HAVE TO PLAY THE PROBABILITY GAME...MEANING...THERE IS A HIGHER THAN NORMAL CHANCE FOR SHOWERS AND THUNDERSTORMS GIVEN ALL THE PARAMETERS ASSOCIATED WITH TROPICAL DEPRESSION JOHN 300 MILES SOUTH OF YUMA... WITH HINTS OF IT MOVING NORTH TOWARD THE AZ BORDER. FOR THE REMAINDER OF THE EVENING... WE ALREADY DOWNGRADED THE PROBABILITY OF SHOWERS AND THUNDERSTORMS TO A SLIGHT CHANCE CATEGORY IN SOUTH CENTRAL AZ...AND REMOVED THE CHANCE COMPLETELY FROM SOUTHEAST CA AND THE COLORADO RIVER. HOWEVER LATEST RADAR AND SATELLITE IMAGERY AT 0330Z (830 PM LOCAL) SHOWED ISOLATED THUNDERSTORMS WITH TOPS TO 40 THSD FEET...MOVING SOUTHWEST FROM OFF THE HIGHER TERRAIN...INTO NORTHEAST MARICOPA COUNTY TOWARD PHOENIX. ADDITIONAL STORMS COULD DEVELOP IN PORTIONS OF THE GREATER PHOENIX AREA THIS EVENING...ALONG OUTFLOW BOUNDARIES...CONSIDERING A VERY MOIST AND QUASI-UNSTABLE 00Z PHOENIX SOUNDING. LOW LEVEL MOISTURE ON THE PHOENIX SOUNDING WAS BORDERLINE EXTREME. FORECASTS LOOK OK FOR NOW. NO ADDITIONAL UPDATES PLANNED. && .LONG TERM... WEDNESDAY NIGHT THROUGH SUNDAY... WEST TO NORTHWEST FLOW IS FORECAST TO DEVELOP ON WEDNESDAY AS UPPER RIDGE SHIFTS A BIT TO THE WEST...WHICH SHOULD RESULT IN A RETURN OF SOMEWHAT DRIER AIR...ESPECIALLY OVER FAR SOUTHEAST CALIFORNIA. HOWEVER...TROUGHING IS FORECAST TO DEVELOP OVER OR NEAR THE WEST COAST BY THURSDAY...AND WEAK TROUGHING WILL LIKELY PERSIST INTO SATURDAY OVER THE WESTERN UNITED STATES. AZ PTN OF CWA WILL BE IN UPPER DIFLUENT/DIVERGENT FLOW ALOFT...AND GFS FORECASTS MOISTURE TO INCREASE FROM THE SOUTH AND EAST AS TROUGHING DEVELOPS...ESPECIALLY OVER AZ PTN OF THE CWA...SO WILL HOLD ONTO CHANCE POPS THRU SATURDAY GIVEN THIS SCENARIO. AS USUAL...DAYTIME HEATING AND POSITION/ EXISTENCE OF WEAK UPPER DISTURBANCES WILL MODULATE THE CONVECTION. EXPECT BELOW NORMAL TEMPERATURES DURING THIS PERIOD...WITH NOT TOO MUCH DAY-TO-DAY CHANGE. ABOVE NORMAL PRECIP LIKELY OVER AZ PTN OF CWA. && .AVIATION... 06Z TAFS ADEQUATELY DEPICT EXPECTED WEATHER. SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL FOR MORE DETAILED INFORMATION. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE.
