AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 230 PM MST SAT SEP 01 2007 .SYNOPSIS...HIGH PRESSURE AND MONSOON MOISTURE WILL CONTINUE TO BRING A CHANCE OF THUNDERSTORMS TO NORTHERN ARIZONA OVER THE NEXT WEEK. OTHERWISE...ABOVE NORMAL TEMPERATURES WILL CONTINUE UNTIL MONDAY THEN LOWER TO NEAR NORMAL LEVELS BY WEDNESDAY OR THURSDAY AS HIGH PRESSURE WEAKENS. && .DISCUSSION...A DEEP LAYER HIGH PRESSURE SYSTEM REMAINS CENTERED OVER THE CALIFORNIA/ARIZONA BORDER THIS AFTERNOON. AS A RESULT...MOST OF NORTHERN ARIZONA WAS LOCATED UNDER A NORTH TO NORTHEAST FLOW REGIME. THE SOUNDING AT FLAGSTAFF SHOWED QUITE A BIT OF MOISTURE IN THE LOW LEVELS RELATIVE TO A COOL AIR MASS ALOFT AND INDICATES A FAIRLY UNSTABLE AIR MASS. ALL SIGNS STILL POINT TOWARD THUNDERSTORMS INITIATING ACROSS THE MOGOLLON RIM AND WHITE MOUNTAINS THEN PUSHING SOUTHWARD INTO THE LOWER DESERTS. THINK A FEW AFTERNOON AND EARLY EVENING SEVERE THUNDERSTORMS WILL BE POSSIBLE OVER NORTHERN GILA AND YAVAPAI COUNTIES. FOR TONIGHT...WITH NORTHEAST FLOW...OUTFLOW BOUNDARIES FROM THUNDERSTORMS IN UTAH AND COLORADO ARE LIKELY TO MOVE ACROSS NORTHEAST ARIZONA AND INITIATE A FEW STORMS. AS A RESULT...WILL BE CARRYING OVERNIGHT POPS HIGHER THAN THE CLIMATOLOGICAL VALUES. FOR SUNDAY AND MONDAY...NOT MUCH CHANGE IN THE CURRENT PATTERN WITH THE POTENTIAL FOR STRONG THUNDERSTORMS TO MOVE OFF THE RIM AND INTO THE LOWER DESERTS TO THE SOUTH DURING THE AFTERNOONS. NORTHEAST FLOW WILL CONTINUE TO DIRECT NIGHTTIME OUTFLOW BOUNDARIES INTO NORTHEAST ARIZONA WITH THE NOCTURNAL THUNDERSTORM THREAT CONTINUING. FOR THE REMAINDER OF THE WEEK...THE PATTERN GETS EXCEEDINGLY COMPLICATED. MOISTURE LOOKS LIKE IT WILL REMAIN IN PLACE WITH AN INTRIGUING INTERACTION BETWEEN THE CURRENT HIGH PRESSURE SYSTEM...A TROUGH FROM THE NORTH AND THE POTENTIAL INPUT OF DEEP MOISTURE FROM THE TROPICS. THE NET RESULT WILL BE THAT THE CHANCE OF SHOWERS AND STORMS WILL CONTINUE THROUGH THE EXTENDED WITH THE POTENTIAL FOR SOME VERY WET DAYS TOWARDS THE END OF NEXT WEEK. MCCOLLUM && .AVIATION...FOR THE 00Z PACKAGE...EXPECT SCT TSRA/SHRA TO CONTINUE THROUGH 03Z WITH CIGS BKN130-150 AND LCL MVFR CONDITIONS IN THE STRONGER STORMS. AFT 03Z SCT SHRA AND WDLY SCT TSRA SHOULD DIMINISH IN AREAL COVERAGE. FOR SUNDAY...EXPECT SCT TSRA TO DEVELOP OVER THE HIGHER TERRAIN BTWN 17Z-19Z. DL && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. &&
