NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Aug 30, 9:30 AM MST, 1 hour 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 930 AM MST WED AUG 30 2006 .SYNOPSIS...MOISTURE WILL SLOWLY INCREASE ACROSS ARIZONA THROUGH THE REMAINDER OF THE WEEK. EXPECT WIDELY SCATTERED THUNDERSTORMS TODAY MAINLY OVER THE WHITE MOUNTAINS AND MOGOLLON RIM AND ISOLATED STORMS ELSEWHERE. SHOWER AND THUNDERSTORM COVERAGE SHOULD INCREASE ACROSS ALL OF NORTHERN ARIZONA ON THURSDAY AND INTO THE WEEKEND. TEMPERATURES ARE EXPECTED TO COOL A FEW DEGREES WITH THE INCREASING CLOUD COVER. && .DISCUSSION... THIS MORNING THE 24 HOUR SFC DEW POINT CHANGES SHOW INCREASES FROM 5 TO 15 DEGREES. THE SATELLITE PW IMAGES ALSO SHOW HIGHER VALUES THIS MORNING VS YESTERDAY OVER MOST LOWER ELEVATION AREAS IN THE CWA. HIGHER TERRAIN AREAS (E.G. VICINITY FLAGSTAFF) SHOW LITTLE 24 HOUR PW CHANGE. CURRENT THINKING IS THAT AREAS NORTH OF A LINE FROM ST JOHNS TO SELIGMAN WILL SEE SOME AFTERNOON CU AND ONLY ISOLATED STORMS. AREAS SOUTH OF THIS LINE HAVE DEEPER MOISTURE. THIS AFTERNOONS POP GRID LOOKS GOOD. DL 3 AM DISCUSSION...MOISTURE IS SLOWLY INCREASING ACROSS THE STATE THIS MORNING WITH DWPTS ACROSS THE LOWER COLORADO RIVER SHOWING A LARGE INCREASE. SATELLITE IMAGERY SHOWS SOME MIDLEVEL CLOUDINESS IS ALREADY DEVELOPING ACROSS THE WRN ZONES AS THIS MOISTURE MOVES NORTHWARD. THUS...HAVE INCREASED POPS IN THESE LOCATIONS. BEST CHANCES FOR PCPN WILL REMAIN OVER THE WHITE MTNS AND MOGOLLON RIM... WITH THE LOWEST CHANCES IN THE NRN ZONES. MODELS CONTINUE TO INDICATE SOME STRENGTHENING OF THE SUBTROPICAL HIGH AS WELL AS A CONTINUATION OF THE MID-LATITUDE WESTERLY FLOW. THIS WILL MAINTAIN ENOUGH OF A PRESSURE GRADIENT TO RESULT IN BREEZY AFTERNOONS EACH DAY. IT WILL ALSO LIMIT THE NORTHWARD PROGRESSION OF THE SUBTROPICAL MOISTURE. EXPECT THAT THE NRN ZONES WILL HAVE ONLY A SLIGHT CHANCE OF SHOWERS EACH DAY...WITH BETTER CHANCES IN THE SRN ZONES. DAY TO DAY PATTERN WILL BE MODULATED BY SMALL SCALE FEATURES EMBEDDED IN THE FLOW...NONE OF WHICH ARE WELL HANDLED BY THE MODELS. LATEST NHC GUIDANCE STILL INDICATES THAT TC JOHN WILL INTENSIFY AND MOVE NWWD ALONG THE MEXICAN COAST AND PASS JUST SOUTH OF THE TIP OF BAJA CALIFORNIA ON FRIDAY. THIS WILL ALMOST CERTAINLY GENERATE A GULF MOISTURE SURGE THAT COULD PUSH INTO NRN AZ BY SAT/SUN. THUS... HAVE INCREASED POPS ACROSS THE CWA FOR SUN/MON. DB && .AVIATION...FOR THE 18Z PACKAGE...TAFS AND TWEBS ADEQUATELY CONVEY EXPECTED CONDITIONS. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS. .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. &&
