NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Jul 30, 12:30 PM MST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 1230 PM MST FRI JUL 30 2010 .SYNOPSIS...AN EXTREMELY MOIST SOUTHEASTERLY FLOW WILL CONTINUE TO BRING SHOWERS AND THUNDERSTORMS TO THE AREA...PRIMARILY DURING THE AFTERNOON AND EVENING HOURS. LOCALLY HEAVY RAINFALL AND THE POSSIBILITY OF FLASH FLOODING WILL CONTINUE FOR THE NEXT SEVERAL DAYS. && .UPDATE...A FLASH FLOOD WATCH HAS BEEN ISSUED FOR ALL NORTHERN ARIZONA FORECAST ZONES AS VERY HEAVY RAINFALL HAS QUICKLY DEVELOPED FROM NUMEROUS STORMS ACROSS THE FORECAST AREA EARLY THIS AFTERNOON. && .DISCUSSION...A VERY MOIST AIRMASS CONTINUES TO RESIDE OVER THE AREA THIS MORNING. CURRENT OBSERVATIONS SHOW OVER 1.2 INCHES PRECIPITABLE WATER AT FLAGSTAFF...OVER 2.0 INCHES AT PHOENIX THIS MORNING. SLIGHT STABILIZATION HAS OCCURRED SINCE YESTERDAY AROUND THE 400 MB LEVEL. INSTABILITY IS NOT OVERLY IMPRESSIVE...AND THE SOUNDING SUPPORTS HEAVY RAIN WITH LIMITED LIFT IN THE PRIME HAIL GROWTH REGIONS FROM ABOUT 23-33 KFT MSL LIMITING HAIL POTENTIAL AND EXTREME MOISTURE LIMITING STRONG WIND POTENTIAL. FAIRLY EXTENSIVE CLOUD COVER OVER PORTIONS OF NORTHERN AZ SHOULD ALSO LIMIT THE INTENSITY OF CONVECTION OVER WHAT MIGHT BE EXPECTED WITH SUCH LARGE PRECIPITABLE WATER VALUES. IN SUMMARY...ANOTHER DAY OF WIDESPREAD PRECIPITATION WITH POCKETS OF VERY HEAVY RAINFALL POSSIBLE. BEST POTENTIAL FOR STRONG STORMS WILL BE IN AREAS WHICH DEVELOP A FEW HOURS OF SUNSHINE IN THE LATE MORNING/EARLY AFTERNOON. CURRENT FORECAST IS ON TRACK AND NO UPDATES PLANNED THIS MORNING. && .PREV DISCUSSION/330 AM MST/...VERY MOIST AIRMASS RESIDING OVER ARIZONA TODAY THROUGH SUNDAY...POSSIBLY LINGERING INTO MONDAY...BEFORE SLIGHTLY DRIER AIR MOVES BACK INTO THE AREA. TEMPERATURES ALOFT DO NOT SHOW ANY COOLING TREND FOR TODAY. SOME COOLING IS INDICATED FOR SATURDAY ALONG WITH SOME INCREASES IN PW VALUES. DID LOOK EXTENSIVELY AT THE DATA COMING IN FOR A POSSIBLE FFA FOR TODAY...DECIDED TO HOLD OFF SINCE THE AIRMASS ADVECTING INTO NORTHERN AZ HAS ITS ORIGINS FROM SOUTH CENTRAL PARTS OF THE STATE...THAT IS CURRENTLY EXPERIENCING ON GOING CONVECTION AS OF 10Z. IF THE DAY SHIFT WARRANTS AND THEY SEE THE CLOUD COVER CLEARING OFF EARLY...SO THAT MORE CAPE CAN BUILD UP EARLY IN THE DAY...THEN A FFA MAY BE NEEDED FOR TODAY. DID PUT INTO THE GRIDS TRW+ WITH MENTION OF HEAVY RAIN POSSIBLE TODAY THROUGH SUNDAY. FOR SATURDAY SOME COOLING ALOFT APPEARS TO OCCUR AS ADVERTISED BY THE MODELS AND WITH THE INCREASE IN MOISTURE...THOSE TWO CONDITIONS MAY BE ENOUGH TO INCREASE THE THREAT OF FLASH FLOODING...AND WARRANT AN FFA. AGAIN IF CLOUD COVER IS TOO DENSE TO BEGIN THE DAY ON SATURDAY...THAT COULD KEEP THE THREAT OF FLASH FLOODING LOW. FOR SUNDAY INTO WEDNESDAY THE LOW PRESSURE THAT MOVE WESTWARD ACROSS ARIZONA WILL CONTINUE TO MOVE FARTHER AWAY TO THE WEST ALLOWING FOR SOME MIDLEVEL DRYING...HOWEVER THE LOW LEVELS WILL STILL REMAIN FAIRLY MOIST...SO EXPECTING MORE OF A MODERATE TO PERHAPS WEAK MONSOON PATTERN SETTING UP FOR NEXT WEEK. && .AVIATION...FOR THE 18Z PACKAGE...SCT-NMRS SHRA/TSRA WILL CONTINUE INTO THE EVENING HOURS...DIMINISHING AFT 04-06Z. HEAVY RAINFALL LIKELY WITH AREAS MVFR AND LOCAL IFR VIS/CIGS PSBL. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS. && .FGZ WATCHES/WARNINGS/ADVISORIES...FLASH FLOOD WATCH IN EFFECT FOR ALL NORTHERN ARIZONA FORECAST ZONES UNTIL MIDNIGHT TONIGHT.
