AZZ020>028-CAZ030>033-110600- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 327 PM MST WED AUG 10 2005 SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... A VERY HUMID...TROPICAL AIRMASS OVER SOUTHEAST CALIFORNIA...AND SOUTHWEST AND SOUTH-CENTRAL ARIZONA WILL LEAD TO A CHANCE OF SHOWERS AND THUNDERSTORMS AGAIN THIS EVENING...SOME STORMS MAY PRODUCE HEAVY RAINFALL. MORE SUNSHINE SHOULD PRODUCE WARMER WEATHER ON THURSDAY...AND THIS COULD LEAD TO THE POSSIBILITY OF ISOLATED SEVERE THUNDERSTORMS IN THE AFTERNOON AND EVENING HOURS. LITTLE CHANGE IN THE WEATHER PATTERN IS EXPECTED THROUGH SATURDAY WITH TEMPERATURES REMAINING AT OR SLIGHTLY BELOW NORMAL. && .DISCUSSION... FORECAST APPEARS ON TRACK TONIGHT. AT 3 PM...SKIES HAVE BECOME PARTLY CLOUDY OVER MUCH OF THE AREA. THE INCREASE IN SUNSHINE HAS ALLOWED TEMPS TO CLIMB INTO THE UPPER 80S TO LOW 90S OVER MOST OF THE DESERT ZONES...ALTHOUGH THIS IS STILL 3 TO 7 DEGREES F LOWER THAN YESTERDAY AT THIS TIME. MOST OF THE CONVECTIVE ACTIVITY SO FAR THIS AFTERNOON HAS OCCURRED OVER LA PAZ...YUMA...AND WESTERN MARICOPA COUNTIES. FOR TONIGHT STILL EXPECTING A 30 TO 40 PERCENT CHANCE OF SHOWERS AND THUNDERSTORMS OVER MOST ZONES. DEBRIS CLOUDS PERSISTED OVER MUCH OF THE AREA THROUGH EARLY AFTERNOON LIMITING THE HEATING...AND THUS THE POTENTIAL FOR EXPLOSIVE CONVECTION. THE CHARACTER OF STORMS TODAY HAVE BEEN RATHER LOW TOPPED...WITH FEW STORMS BUILDING ABOVE 35K FEET. WITH VERY LOW LCL AND LFC HEIGHTS...STORMS ARE ABLE TO FORM EASILY...BUT THE LACK THE OF HEATING IS PRODUCING LONG/SKINNY CAPE PROFILES. THIS TREND IS EXPECTED TO CONTINUE TONIGHT UNLESS SIGNIFICANT WARMING TAKES PLACE BEFORE SUNSET. THE MAIN THREAT TONIGHT WILL BE LOCALLY HEAVY RAINFALL AS THE ATMOSPHERE REMAINS INCREDIBLY MOIST WITH PRECIPITABLE WATER VALUES AROUND 2 INCHES. AN ISOLATED SEVERE STORM (WET MICROBURST) IS ALSO POSSIBLE. STORMS OVER SOUTH CENTRAL AZ APPEAR TO PROPAGATING A BIT QUICKER TODAY...AND THIS IS REFLECTED IN THE 700-300MB STEERING FLOW OF 10 TO 15 KTS. FOR TOMORROW...LITTLE CHANGE IN THE OVERALL SYNOPTIC PATTERN. THE 300MB UPPER HIGH IS EXPECTED TO WOBBLE IN THE VICINITY OF THE AZ/NM BORDER...WHILE A DISTURBANCE RIDES UP ALONG THE BAJA CA COAST. NAM/GFS CONTINUE TO DEVELOP A 30 TO 40KT JET AT 300MB BETWEEN THESE FEATURES...ALONG WITH AN OVERALL DIFFLUENT FLOW OVER THE CWA BY 06Z. THIS UPPER LEVEL SUPPORT...COMBINED WITH MORE INSOLATION/HEATING MAY LEAD AN ENHANCED POTENTIAL FOR SEVERE STORMS TOMORROW...ALONG WITH THE POSSIBILITY OF CONTINUED HEAVY RAINFALL. AS USUAL...A LOT WILL DEPEND ON HOW MUCH CONVECTIVE ACTIVITY OCCURS TONIGHT...AND HOW MUCH DEBRIS CLOUDINESS IS PRESENT DURING THE MORNING HOURS TOMORROW. BY THIS WEEKEND INTO EARLY NEXT WEEK...THE MEDIUM RANGE MODELS CONTINUE TO ADVERTISE A SERIES OF SHORTWAVES AFFECTING THE SOUTHWEST. THERE IS THE POSSIBILITY OF SOME DRYING FROM THE WEST TAKING PLACE...ESPECIALLY OVER SERN CALIFORNIA...WHICH COULD RESULT IN THE REDUCTION OR ELIMINATION OF THUNDERSTORMS. HOWEVER...AS THE SYSTEMS MOVE INTO THE REGION...INCREASED SHEAR AND SOME UPPER LEVEL Q-G FORCING COULD LEAD TO DEVELOPMENT OF SEVERE WEATHER...ESPECIALLY IF THE LOW LEVEL MOISTURE IS ABLE TO STAY PUT. DUE TO UNCERTAINTIES IN TIMING AND STRENGTH OF SYSTEMS...AND AVAILABILITY OF MOISTURE...DECIDED NOT TO MAKE IN BIG CHANGES AT THIS TIME. && .AVIATION... DISCUSSION FOR 00Z TAFS. LOWER CLOUDS...WITH CIGS BLO 6K FT CAN STILL BE EXPECTED LATER TODAY WITH SOME OF THE STRONGER STORMS. BRF VSBY TO BLO 3 MI MAY ALSO OCCUR IN/NEAR THESE CELLS. TAFS ADEQUATELY DEPICT CURRENT WEATHER. SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH...LAXTAFIPL FOR MORE DETAILED INFORMATION. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE.
