AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1050 AM MST MON JUL 14 2008 SOUTH-CENTRAL AND SOUTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .UPDATE...UPDATED AVIATION DISCUSSION. && .SYNOPSIS... A VERY MOIST AIRMASS ACROSS ARIZONA WILL KEEP PLENTY OF CLOUDS AROUND WITH RELATIVELY COOL AFTERNOON HIGHS. SCATTERED SHOWERS AND THUNDERSTORMS CAN BE EXPECTED THIS AFTERNOON...WITH LOCALLY HEAVY RAINFALL. MUCH OF SOUTHEAST CALIFORNIA WILL REMAIN DRY TODAY. THE AIRMASS IS EXPECTED TO GRADUALLY BECOME DRIER AND WARMER BY THE MIDDLE OF THE WEEK...AS HIGH PRESSURE ALOFT BUILDS OVER ARIZONA. THIS WILL REDUCE THE CHANCES OF SHOWERS AND THUNDERSTORMS. WEATHER MODELS ARE INDICATING THUNDERSTORM ACTIVITY MAY INCREASE THIS WEEKEND. && .DISCUSSION... HAVE INCREASED POPS FOR TODAY ACROSS S-CNTRL AZ AND SWITCHED WEATHER WORDING FROM PROBABILITY TO COVERAGE WORDING. HAVE ALSO HIGHLIGHTED POTENTIAL FOR LOCALLY HEAVY RAIN THIS AFTERNOON/EVENING IN THE ZONES/GRIDS. LOOKING AT 12Z UPPER AIR DATA...KPSR SOUNDING IS EXCEPTIONALLY MOIST WITH A PRECIPITABLE WATER JUST OVER TWO INCHES. MID SHIFT LOWERED HIGH TEMPERATURES FOR TODAY...WHICH LOOKS TO BE A GOOD CALL. THE LOWER TEMPERATURES WILL PUT A BIT OF A LID ON CAPE/INSTABILITY GETTING OUT OF CONTROL. EVEN STILL...MODEST WARMING GIVES CAPE VALUES NEAR 1000. MAIN FACTOR IN INCREASING POPS FOR TODAY WAS BASED ON LATEST WATER VAPOR AND IR SATELLITE IMAGERY. HARD TO ASSESS...BUT APPEARS THAT THERE ARE STILL SEVERAL SMALL CIRCULATIONS/PERTURBATIONS IN THE SWLY FLOW. LOOKING BACK AT YESTERDAY...APPEARS THAT IT WAS ONE OF THESE SMALL WAVES WHICH HELPED KICK-OFF CONVECTION. WITH A SIMILAR FLOW...AND GIVEN THE AIRMASS...FELT POPS NEEDED TO BE HIGHER. PRECIPITABLE WATER NEAR 2 INCHES NECESSITATED HEAVY RAIN WORDING. WOULD CONSIDER A FLASH FLOOD WATCH...BUT NOT SOLD THAT CONVECTIVE COVERAGE WOULD BE WIDESPREAD ENOUGH TO WARRANT IT. WILL CONTINUE TO MONITOR THAT THOUGH THROUGH THE DAY. PREVIOUS DISCUSSION... OTHERWISE...THE QUESTION FOR TODAY IS...HOW CONVECTIVELY ACTIVE WILL IT GET? OVER SOUTH CENTRAL ARIZONA...CONSIDERABLE CONVECTIVE DEBRIS CLOUDS LINGERING INTO THE MORNING HOURS...ALONG WITH MUCH COOLER SURFACE TEMPERATURES TEND TO STABILIZE THE ATMOSPHERE SOMEWHAT. HOWEVER...THERE IS STILL SOME UPPER LEVEL WEAKNESS (300 MB AND ABOVE) OVER THE EASTERN HALF OF AZ THAT COULD SUPPORT ANOTHER ROUND OF MOUNTAIN THUNDERSTORMS LATER IN THE DAY. WESTWARD MOVING OUTFLOW BOUNDARIES FROM THIS CONVECTION COULD TRIGGER CENTRAL DESERT CONVECTION BY EVENING...INCLUDING PHOENIX. UPPER LEVEL SPEED DIVERGENCE...OR REAR ENTRANCE JET DYNAMICS...IS FORECAST OVER THE EASTERN MOGOLLON RIM AND WHITE MOUNTAINS TODAY. IN OTHER WORDS...15 KNOT 250 MB WINDS OVER CASA GRANDE ACCELERATE ANTI-CYCLONICALLY INTO A 45 KNOT JET MAX OVER NORTHWEST NEW MEXICO THIS AFTERNOON...WEAKER ON TUESDAY. OVER SOUTHEAST CA AND SOUTHWEST AZ...NOT MUCH UPPER LEVEL SUPPORT IS EXPECTED THOUGH VERY HUMID CONDITIONS COULD STILL PROVIDE A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS TODAY AND TUESDAY... MAINLY OVER THE HIGHER TERRAIN. WEDNESDAY AND THURSDAY... LOW LEVEL MONSOON MOISTURE WILL BE THINNING SOMEWHAT. THEREFORE ONLY A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS...MAINLY OVER SOUTHWEST AND SOUTH CENTRAL AZ ARE EXPECTED. FRIDAY AND SATURDAY... A WEAKENING INVERTED TROF MOVING NORTH FROM MEXICO COULD TRIGGER ANOTHER ROUND OF WIDESPREAD CONVECTION OVER SOUTH CENTRAL...AND PARTS OF SOUTHWEST AZ. AND...A LARGER UPPER LEVEL INVERTED TROF IS FORECAST TO MOVE TOWARD AZ FROM WEST TEXAS THIS WEEKEND. && .AVIATION... SOUTH-CENTRAL ARIZONA...INCLUDING KPHX/KIWA AND SURROUNDING AIRFIELDS...SHOWERS ARE CONTINUING TO DEVELOP TO THE NORTHWEST OF THE PHOENIX METRO AREA...WITH THUNDERSTORM DEVELOPMENT OFF TO AN EARLY START TODAY IN THE HIGHER TERRAIN OF SOUTHERN GILA COUNTY. PLENTIFUL MOISTURE REMAINS TODAY...SO THUNDERSTORM ACTIVITY IS CERTAINLY A POSSIBILITY FOR THE LOWER DESERT FLOORS. IT APPEARS THE FAVORED AREAS WILL BE TO THE NORTH AND EAST OF THE GREATER PHOENIX AREA THIS AFTERNOON. HAVE OPTED TO KEEP MENTION OF T-STORMS AND WIND SHIFTS ASSOCIATED WITH OUTFLOW OUT OF THE TAFS FOR NOW...DUE TO UNCERTAINTY OF TIMING AND LOCATION...BUT WILL AMEND IF TRENDS LEAD TO INCREASED CONFIDENCE OF THUNDERSTORM ACTIVITY IN THE PHOENIX METRO AREA. SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA...KNYL/KBLH AND KIPL... THE MAIN THREAT FOR PRECIPITATION WILL STAY TO THE EAST OF THE LOWER CO RIVER TODAY AND TONIGHT...WITH ONLY A SLIGHT CHANCE FOR MAINLY AFTERNOON/EVE STORMS ACROSS THE AREA. WINDS WILL FAVOR THE SOUTH GENERALLY LESS THAN 20 MPH TODAY...WITH A TENDENCY TO TURN MORE TO THE SOUTHWEST OR WEST AFTER 22Z. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... TUESDAY THROUGH SATURDAY... CONVECTIVE ACTIVITY WILL GENERALLY TREND DOWN TUESDAY THROUGH THURSDAY...ESPECIALLY FROM THE COLORADO RIVER WESTWARD. TEMPERATURES WILL RISE BACK TO NEAR NORMAL LEVELS...WITH RH VALUES TREND DOWN SLOWLY...THOUGH SIGNIFICANT DRYING IS NOT EXPECTED OVER THE SOUTH-CENTRAL ARIZONA. MODELS HINTING THAT MOISTURE LEVELS COULD INCREASE AGAIN TOWARD NEXT WEEKEND...WHICH WILL BEAR MONITORING. OTHERWISE NO SIGNIFICANT FIRE WEATHER CONCERNS AT THIS TIME. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE. CA...NONE. && NATIONAL WEATHER SERVICE PHOENIX IS ON THE INTERNET AT WEATHER.GOV/PHOENIX DISCUSSION...INIGUEZ/VASQUEZ AVIATION...ROGERS FIRE WEATHER...CB
