AZZ020>028-CAZ030>033-020000- AREA FORECAST DISCUSSION...UPDATED AVIATION DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1100 AM MST WED AUG 1 2007 SOUTH-CENTRAL AND SOUTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... A VERY MOIST AND UNSTABLE ATMOSPHERE WILL REMAIN ENTRENCHED OVER THE DESERT SOUTHWEST INTO THE UPCOMING WEEKEND. AT THE SAME TIME...WEAK WEATHER DISTURBANCES WILL MOVE INTO THE REGION...RESULTING IN AN INCREASED THREAT FOR SHOWERS AND THUNDERSTORMS...MOSTLY DURING THE AFTERNOON AND EVENING HOURS. SINCE THE STORMS WILL BE SLOW-MOVING... HEAVY RAIN WILL BE THE MAIN THREAT. && .SHORT TERM... TODAY THROUGH FRIDAY... ISOLD TSTMS STILL RUMBLING OUT IN FAR WRN CWA NEAR THE SALTON SEA... WITH LOTS OF DEBRIS CLOUDINESS OVERLAYING THE REMAINDER OF THE FCST AREA. THIS DEBRIS CLOUD SHIELD WILL BE SLOW TO BURN OFF AND WILL THEREFORE DELAY OUR NEXT BATCH OF STORMS UNTIL LATER IN THE DAY. EXCEPTION TO THIS WILL BE OVER SRN GILA COUNTY ZONE...WHERE INSOLATION HAS ALREADY COMMENCED...AND ELEVATED SOUNDING PROJECTIONS SHOW AN EARLIER ONSET. MEANWHILE...WV IMAGERY SHOWS A HIGH CENTER OVER SRN COLORADO AND ANOTHER NEAR THE BIG BEND...WITH A MID-LEVEL TROUGH AXIS/DEFORMATION ZONE STRETCHED IN BETWEEN THE CENTERS WWD INTO CENTRAL AZ. THIS COULD SERVE TO FOCUS SOME ACTIVE CONVECTION LATE TODAY INTO THIS EVENING ACROSS SCNTRL ZONES ONCE CONVECTIVE TEMPS ARE REACHED. STEERING FLOWS ARE VERY WEAK...AND WITH PWATERS OVER THE DESERT FLOORS OF NEAR 2 INCHES...LOOK FOR MORE SLOW-MOVING HEAVY RAIN-PRODUCING STORMS...FORMING/ENHANCING ALONG OUTFLOW BOUNDARY INTERSECTIONS. EXPECTING LITTLE CHANGE ON THURSDAY/FRIDAY AS SYNOPTIC SCALE FEATURES CHANGE ONLY SLIGHTLY. POP/WX GRIDS...AS WELL AS TEMPS...ALL APPEAR REASONABLE. ALREADY UPDATED FOR MORE CLOUDS AND ISOLD SHOWERS OUT IN WRN ZONES...NO OTHER UPDATES NEEDED ATTM. && .LONG TERM... FRIDAY NIGHT THROUGH TUESDAY... ANOTHER INVERTED TROF IS EXPECTED TO MOVE INTO SOUTHEAST AZ FROM TEXAS AND NORTHWEST MEXICO SUNDAY AND MONDAY...RESULTING IN AN UPSWING IN CONVECTION OVER CENTRAL AND EASTERN AZ. MODELS HOWEVER ...ARE FORECASTING AN INCREASINGLY DRY PACIFIC WESTERLY FLOW BY LATE TUESDAY...FOR A REDUCED THREAT OF SHOWERS AND THUNDERSTORMS OVER SOUTHEAST CA AND SOUTHWEST AZ. OTHERWISE...A BROAD BRUSH APPROACH TO FORECASTS FOR SOUTH CENTRAL AZ (MEANING A CHANCE FOR AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS) WILL CONTINUE THROUGH TUESDAY. && .AVIATION... AUGUST 1 1800 UTC (1100 MST) AT 1730 UTC...SIGNIFICANT MID-HIGH LEVEL DEBRIS CLOUDS WERE DRAPED ACROSS MUCH OF ARIZONA...EXCEPT FOR PORTIONS OF THE SOUTHEAST AND NORTHEAST CORNERS OF THE STATE. SCATTERED SHOWERS AND THUNDERSTORMS NEAR AND WEST OF KLAS WERE ALSO MOVING SLOWLY WESTWARD ACROSS SOUTHERN NEVADA AND AREAS OF SOUTHEAST CALIFORNIA WEST OF KEED. EXTENDING SOUTH FROM THIS LINE...SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WERE IMPACTING IMPERIAL COUNTY WEST OF KIPL AND PORTIONS OF EASTERN RIVERSIDE COUNTY WEST OF KBLH. ENOUGH OF A CONCERN TO ADD VCSH AT KBLH AND VCTS AT KIPL FOR THE NEXT FEW HOURS. KYUM SHOULD REMAIN DRY. AS FOR KPHX/KIWA AND VALLEY AIRFIELDS...THICK CLOUD COVER THIS MORNING AND A MORE STABLE LOWER ATMOSPHERE (PER THE 12 UTC PSR SOUNDING) WILL HELP LIMIT THUNDERSTORM ACTIVITY THROUGH MUCH OF THE AFTERNOON. SCATTERED SHOWERS AND THUNDERSTORMS WILL STILL DEVELOP ALONG THE HIGHER TERRAIN SURROUNDING THE VALLEY OVER THE NEXT SEVERAL HOURS... MOVING LITTLE GIVEN WEAK UPPER LEVEL STEERING FLOW. HOWEVER...THE EXTENT AND TIMING TO WHICH THESE STORMS MIGHT REACH THE DESERT FLOOR IS UNCERTAIN. THUS...WILL KEEP MENTION OF CB/S AT KPHX/KIWA...ONLY TO AMEND FOR VCSH/VCTS AFTER A BETTER PICTURE OF CONVECTION FOR THE DAY IS AVAILABLE. STAY TUNED... SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL FOR MORE DETAILED INFORMATION. AVIATION DISCUSSION IS NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... AUG 1 1240 UTC (AUG 1 0540 MST) ELEVATED PRECIPITATION CHANCES WILL CONTINUE THROUGH THE WEEKEND...WITH THE GREATEST PROBABILITIES ELEVATED SITES IN ARIZONA...AND THE LOWEST PROBABILITIES ACROSS THE DESERTS OF SOUTHEAST CALIFORNIA. A BROAD UPPER LEVEL TROUGH WILL APPROACH THE REGION FROM THE NORTHWEST BY EARLY NEXT WEEK. THIS WILL START A DRYING TREND...WHICH WILL RESULT IN THE REDUCTION OF PRECIPITATION CHANCES AS WELL AS A LOWERING OF RH VALUES. WINDS WILL LIKELY INCREASE AHEAD OF THE SYSTEM...RESULTING IN GUSTY AFTERNOON AND EVENING WINDS. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE.
