AZZ020>028-CAZ030>033-100000- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1006 AM MST TUE AUG 9 2005 SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... A VERY MOIST MONSOONAL AIRMASS WILL CONTINUE TO COVER SOUTHEAST CALIFORNIA...AND SOUTHWEST AND SOUTH CENTRAL ARIZONA THIS WEEK AND WEEKEND. AS A RESULT...THE CHANCE FOR MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WILL CONTINUE...WITH THUNDERSTORM COVERAGE AND INTENSITY VARYING FROM DAY TO DAY. && .DISCUSSION... VERY MOIST MONSOONAL AIRMASS REMAINS ENTRENCHED OVER THE REGION THIS MORNING AS DEPICTED IN LATEST 12Z RAOB PLOTS AND SURFACE DATA. CLOSEST TO HOME...MORNING SOUNDING AT KPSR INDICATED 850MB (700MB) DEWPOINTS OF 17C (6C) RESULTING IN A ROBUST TOTAL PW VALUE OF 2.12 INCHES...A SLIGHT INCREASE OVER YESTERDAY. SURFACE DEWPOINTS AROUND THE CWA WHERE ALL IN THE 60S TO LOW 70S...PRODUCING A TROPICAL FEEL TO THE AIRMASS. A COUPLE AREAS OF CONVECTIVE ACTIVITY WERE STILL ONGOING...A DYING MCS OVER NORTHERN MEXICO...AND A BACKBUILDING MCS OVER SOUTHERN NEVADA. A FEW PRECIP ECHOES WERE NOTED OVER THE CWA...MAINLY ACROSS WRN MARICOPA COUNTY AND PORTIONS OF YUMA AND LA PAZ COUNTIES. CURRENT FORECAST HAS SLIGHT CHANCE POPS THIS MORNING OVER MOST AREAS...AND THIS LOOK GOOD. MAIN CHALLENGES IN THE SHORT TERM REVOLVE AROUND CONVECTIVE POTENTIAL THIS AFTERNOON. UPPER AIR PLOTS SHOW THE 300-250MB HIGH CENTERED NEAR THE AZ/NM BORDER...WITH THE 500MB HIGH CENTERED A BIT FURTHER NORTH OVER SOUTHERN CO. AT 500MB A WEAK INVERTED TROUGH WAS ALSO NOTED EXTENDED FROM NEAR THE BAJA SPUR NORTHWARD THROUGH NE AZ. NO CLEAR CUT SIGN THAT A REALLY ACTIVE DAY IS IN STORE...BUT WEAK DIFFLUENCE ALOFT SHOULD ALLOW FOR SOME RATHER VIGOROUS STORMS TO DEVELOP. HOWEVER...PESKY DEBRIS CLOUDINESS OVER THE AREA NOT ALLOWING FULL INSOLATION AT THIS TIME...ALTHOUGH SOME DISSIPATION IN CLOUDS NOTED AS OF LATE. IF WE DO GET SUBSTANTIAL SUNSHINE AND TEMPS ARE ALLOWED TO WARM RAPIDLY...NO DOUBT WE WILL HAVE SOME DECENT CAPE OVER THE AREA. MODIFIED KPSR SOUNDING FOR A MAX TEMP OF 92 AND MEAN MIXING RATIO OF 13 G/KG YIELDS A MLCAPE VALUE OF NEARLY 1500 J/KG. THUS WE SHOULD HAVE NO TROUBLE GETTING STORMS GOING IN THE HIGHER TERRAIN IF WE HAVE ANY SUN AT ALL. AS HAS BEEN THE CASE THE PAST SEVERAL DAYS...STEERING FLOW WILL BE WEAK SO ANY STORMS THAT DO FORM WILL BE SLOW MOVING AND EFFICIENT RAIN PRODUCERS. THUS LOCALLY HEAVY RAIN WILL BE POSSIBLE...ALONG WITH POSSIBLE WET MICROBURSTS WITH ANY TALL STORMS. TEMPS TODAY LOOK ON TRACK. NOT MUCH CHANGE IN THE THINKING FOR TOMORROW AS THE UPPER HIGHS WOBBLE OVER NM/CO. INTERESTING TO NOTE THAT THE GFS DOES BRING WHAT APPEARS TO BE A CONVECTIVELY INDUCED VORTMAX THROUGH THE AREA TOMORROW. AS SUCH THE MAV GUIDANCE FOR KPHX SHOWS A POP OF 65 AT 00Z ON 11 AUG. AT THIS TIME...WILL NOT BUY INTO THIS SOLUTION AND WILL KEEP THE STANDARD CHANCE FOR MAINLY AFTERNOON AND EARLY NIGHTTIME SHOWERS AND THUNDERSTORMS GOING. HAVENT HAD MUCH TIME TO LOOK AT THE EXTENDED...ALTHOUGH A SERIES OF FAIRLY SIGNIFICANT SHORTWAVES APPEARS TO TRACK THROUGH THE REGION ON WEDNESDAY THROUGH THE UPCOMING WEEKEND. MORE ON THIS IN THE AFTERNOON DISCUSSION. && .AVIATION... DISCUSSION FOR 18Z TAFS. TAFS ADEQUATELY DEPICT CURRENT WEATHER.
