NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Jul 30, 2:40 PM MST, 5 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 240 PM MST SUN JUL 30 2006 .SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL ALLOW THUNDERSTORMS TO CONTINUE WELL INTO THE EVENING HOURS TONIGHT...SOME WITH LOCALLY HEAVY RAINS. MOISTURE IS EXPECTED TO REMAIN OVER ARIZONA THROUGH THE UPCOMING WEEK WITH A CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY...ALTHOUGH A SLOW DRYING TREND WILL DECREASE AREAL COVERAGE BY MIDWEEK. && .DISCUSSION...RADAR AND SATELLITE IMAGERY SHOWING THREE MAIN AREAS OF CONVECTION AT THIS TIME. ONE AREA...WITH ATTENDANT LARGE RAINFALL RATES...IS LOCATED OVER THE COCONINO PLATEAU AREA. THIS CONVECTION CAUGHT UP IN RIDGE AXIS DEFORMATION ZONE WITH LITTLE MOVEMENT SHOWN. SOUTHERN PORTION OF THIS WILL MOVE SOUTHEASTWARD TOWARD FLAGSTAFF OVER THIS AFTERNOON AND INTO THE EVENING. SECOND AREA FORMED OFF THE CHUSKA MOUNTAINS AND IS CURRENTLY PUSHING SOUTHWEST TOWARD THE LITTLE COLORADO RIVER VALLEY. THIRD AREA IS LOCATED OVER THE EASTERN LITTLE COLORADO RIVER VALLEY AND MOGOLLON RIM...TO THE WHITE MOUNTAINS. THIS AREA IS PUSHING SOUTHWARD. EXPECT AREAS IN BETWEEN TO DEVELOP THUNDERSTORMS LATER THIS AFTERNOON AS OUTFLOWS CONVERGE AND INTERACT. EXPECT ACTIVITY TO LAST WELL INTO THE EVENING HOURS DUE TO THE HIGH LEVELS OF MOISTURE AND INSTABILITY IN PLACE OVER THE REGION...WITH GENERAL MOTION TO THE SOUTH AND OUT OF THE FORECAST AREA BY MIDNIGHT. FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH MIDNIGHT TONIGHT GENERALLY SOUTH OF A LINE FROM THE GRAND CANYON TO CAMERON TO SANDERS. STEERING FLOW BECOMES WESTERLY MONDAY WHICH WILL BEGIN A SLOW DRYING TREND FOR THE WEEK. EXPECT ACTIVITY MONDAY TO STILL BE HEAVY RAIN PRODUCING THUNDERSTORMS WITH SIMILAR COVERAGE AS TODAY. AS THE FLOW STRENGTHENS ALOFT TUESDAY AND WEDNESDAY...SLIGHTLY DRIER AIR MOVES INTO THE REGION...AND STRONGER WIND SHEAR PROFILE SUGGESTS THE POTENTIAL FOR ISOLATED SEVERE STORMS ON THESE DAYS. ADDITIONAL DRY AIR IS FORECAST TO MOVE IN FROM THE WEST LATER IN THE WEEK TO CONTINUE TO REDUCE THE THUNDERSTORM COVERAGE...ESPECIALLY WESTERN SECTIONS. HOWEVER...LOW-LEVELS REMAIN MOIST ENOUGH FOR DAILY AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS OVER MUCH OF THE HIGHER TERRAIN AREAS OF THE MOGOLLON RIM AND WHITE MOUNTAINS EVEN IN THIS DRIER AIRMASS. COVERAGE WILL BE LESS THAN NORMAL...BUT IT CERTAINLY WONT BE A DRY FORECAST. STAUDENMAIER && .AVIATION...FOR THE 00Z PACKAGE...SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE REGION THROUGH 07Z WITH HEAVY RAIN...VISIBILITIES LOCALLY REDUCED TO UNDER 1SM AND CEILINGS AOB 2000 FT AGL. THUNDERSTORMS WILL GRADUALLY DECREASE IN COVERAGE AFTER 07Z. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS. && .FGZ WATCHES/WARNINGS/ADVISORIES...FLASH FLOOD WATCH UNTIL MIDNIGHT MST TONIGHT FOR ZONES AZZ007-008-012>018-037-038. &&

EXPECT THE GREATEST ACTIVITY FROM THE COCONINO PLATEAU...ALONG THE MOGOLLON RIM...TO THE WHITE MOUNTAIN...AND SOUTH OF THESE AREAS.
