THE RESULT WILL BE SCATTERED SHOWERS AND THUNDERSTORMS. A SLOW WEST TO EAST DRYING TREND ACROSS ARIZONA WILL BEGIN DURING THE MIDDLE PORTION OF NEXT WEEK... BRINGING A DECREASE IN THUNDERSTORM ACTIVITY AND WARMER DAYTIME TEMPERATURES. && .DISCUSSION...COLLIDING BOUNDARIES CONTINUE TO PRODUCE THUNDERSTORMS SOUTH OF DOUGLAS THIS MORNING AND WILL NEED CLOSE MONITORING. ON FRIDAY COCHISE COUNTY WAS INUNDATED WITH COPIOUS RAIN AND WIDESPREAD FLASH FLOODING. WITH THE SOILS SATURATED ANY ADDITIONAL MODERATE OR GREATER RAINFALL FOR ANY SIGNIFICANT LENGTH OF TIME WILL CAUSE MORE FLASH FLOODING... A DEFINITE POSSIBILITY TODAY AS THE FOCUS OF INCREASING MOISTURE REMAINS ALONG THE ARIZONA/NEW MEXICO BORDER. A SHORT WAVE TROUGH JUST NORTH OF THE BAJA SPUR CONTINUES TO PUMP MOISTURE NORTHWARD. ALONG WITH AMPLE DEEP MOISTURE... A DIFFLUENT SOUTH TO NORTH 30 KNOT FLOW ALOFT WILL HELP BUILD THUNDERSTORMS OVER SOUTHEASTERN ARIZONA AGAIN TODAY. BEYOND TODAY... THE SHORT WAVE RIDGE CURRENTLY OVERHEAD WILL BEGIN TO BREAK DOWN AS THE DISTURBANCE NEAR THE BAJA SPUR MOVES NORTHEASTWARD IN THE WAKE OF A LONGER WAVE TROUGH DROPPING OUT OF WESTERN CANADA. AS THE IMPULSE MOVES NORTHEASTWARD IT WILL PROVIDE ADDITIONAL DYNAMICS TO THE ALREADY MOIST AND UNSTABLE AIR MASS OVER SOUTHERN ARIZONA FOR ANOTHER ACTIVE DAY ON SUNDAY. AFTER ITS PASSAGE HOWEVER THE LONGER WAVE TROUGH WILL BEGIN TO DRY OUT THE UPPER LEVELS RESULTING IN A SLOW DRYING TREND THROUGH THE WEEK. BUT... THE POSSIBILITY OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS WILL CONTINUE. AS THE AIR MASS SLOWLY DRIES AFTERNOON TEMPERATURES WILL RESPOND BY RETURNING TO NEAR OR ABOVE NORMAL BY NEXT WEEKEND. && .AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && EVANS WEATHER.GOV/TUCSON
HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE TUCSON AZ 1042 AM MST FRI AUG 12 2005 AZZ019-029>035-131400- NORTHERN GREENLEE COUNTY-SOUTHEAST PINAL COUNTY- UPPER GILA RIVER VALLEY-WESTERN PIMA COUNTY-TOHONO OODHAM NATION- TUCSON METRO/MARANA/GREEN VALLEY-SANTA CRUZ COUNTY-COCHISE COUNTY- 1042 AM MST FRI AUG 12 2005 THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ARIZONA. .DAY ONE...TODAY AND TONIGHT SYNOPSIS...EXPECT SHOWERS AND THUNDERSTORMS TO INITIALLY DEVELOP OVER THE HIGHER TERRAIN LATE THIS MORNING AND INTO THE EARLY AFTERNOON...WITH STORMS MOVING SLOWLY TO THE SOUTHEAST AT 5 TO 10 MPH. STORM INTENSITY WILL BE ENHANCED EAST OF A LINE FROM SASABE TO ELOY TODAY THANKS TO A DIVERGING WIND FLOW IN THE UPPER ATMOSPHERE. THE SLOW MOVEMENT OF STORMS AND ENHANCED THUNDERSTORM ACTIVITY ACROSS THE SOUTHEAST CORNER OF THE STATE...WILL MAKE THE MAIN THREAT LOCALIZED FLASH FLOODING. A SLIGHTLY ELEVATED THREAT OF DAMAGING WINDS IS PRESENT ALONG A LINE FROM SASABE TO ELOY ALONG A MOISTURE BOUNDARY ALOFT. DISCUSSION...THE LATEST PRECIPITABLE WATER IMAGERY INDICATED DEEP MID-LEVEL MOISTURE WAS PRESENT ACROSS ALL OF SOUTHEAST ARIZONA... WITH THE DEEPEST LOW-LEVEL MOISTURE POSITIONED ACROSS THE WESTERN DESERTS. SURFACE DEWPOINTS...A GOOD MEASURE OF LOW LEVEL MOISTURE... WERE GENERALLY IN THE LOWER 60S THIS MORNING ACROSS VALLEY LOCATIONS. AN UPPER LEVEL LOW PRESSURE AREA ACROSS THE NORTHERN BAJA PENINSULA HAS PRODUCED AN AREA OF DIFFLUENT FLOW ACROSS THE MAJORITY OF SOUTHEAST ARIZONA. THE BEST DIVERGENCE ALOFT WILL BE EAST OF A LINE FROM SASABE TO ELOY...AND WILL ENHANCE THUNDERSTORM DEVELOPMENT AND INTENSITY. THE LATEST GOES-10 WATER VAPOR IMAGERY INDICATED THAT A PLUME OF DRIER AIR ALOFT WILL CONTINUE TO ROTATE NORTHWARD INTO SOUTH CENTRAL ARIZONA BY THIS AFTERNOON. THIS MOISTURE BOUNDARY...MAINLY ALONG A LINE FROM SASABE TO ELOY...WILL ALSO SERVE AS A FOCUSING MECHANISM FOR THUNDERSTORMS. A MID-LEVEL HIGH PRESSURE AREA NEAR LAS VEGAS WILL PUSH STORMS SLOWLY TO THE SOUTHEAST AT 5 TO 10 MPH THIS AFTERNOON. THE LACK OF ANY SIGNIFICANT SHEAR WOULD SUGGEST THAT THE MAJORITY OF STORMS TODAY WILL BE OF THE PULSE TYPE VARIETY. THE SLOW STORM MOTION WOULD ALSO SUGGEST AN INCREASED RISK OF LOCALIZED HEAVY DOWNPOURS...AND RESULTING POSSIBILITY OF FLASH FLOODING...ESPECIALLY ACROSS THE AREA WITH THE BEST UPPER-LEVEL DIFFLUENCE...EAST OF A LINE FROM SASABE TO ELOY. FURTHER WEST...ALONG THE MOISTURE BOUNDARY ALOFT THERE IS A SLIGHTLY ELEVATED RISK OF STRONG THUNDERSTORM DOWNDRAFTS PRODUCING DAMAGING WINDS. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH TUESDAY THERE WILL BE SCATTERED AFTERNOON AND EVENING THUNDERSTORMS THROUGHOUT THE PERIOD WITH THE POSSIBILITY OF LOCALIZED FLASH FLOODING AND DAMAGING WINDS POSSIBLE. .SPOTTER INFORMATION STATEMENT...
