AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
210 PM MST SUN JUN 29 2008

.SYNOPSIS...HIGH PRESSURE ALOFT WILL BECOME CENTERED OVER THE GREAT
BASIN REGION BY MONDAY. THUNDERSTORM ACTIVITY WILL INCREASE TODAY
INTO MONDAY AS EASTERLY FLOW TRANSPORTS MOISTURE INTO THE AREA.
OTHERWISE...HOT DAYTIME TEMPERATURES WITH A SLIGHT CHANCE OF
AFTERNOON AND EVENING THUNDERSTORMS WILL OCCUR THE REST OF THE WEEK.

&&

.DISCUSSION...SATELLITE AND RADAR IMAGERY WAS SHOWING A LARGE
THUNDERSTORM CLUSTER THAT DEVELOPED OVER MOUNT BALDY IN THE WHITE
MOUNTAINS. OTHER STORMS HAD DEVELOPED IN THE CHIRICAHUA MOUNTAINS
AND MOVED WEST OVER THE VALLEY BETWEEN ELFRIDA AND SUNSITES. STORMS
IN THE GILA WILDERNESS OF WEST-CENTRAL NEW MEXICO WERE ALSO STARTING
TO MERGE WITH THE CLUSTER DRIFTING SOUTHWEST OFF MOUNT BALDY. EXPECT
STORMS TO BECOME MORE ORGANIZED IN THE WHITE MOUNTAINS DURING THE
NEXT HOUR...AND TRACK SOUTHWEST TOWARD THE GILA RIVER VALLEY AROUND
SAFFORD BY 4 PM MST. THE AIRMASS ACROSS THE LOWER DESERTS SHOULD BE
UNSTABLE ENOUGH THIS EVENING TO SUPPORT THUNDERSTORMS IF AN
ORGANIZED OUTFLOW FROM THE PROGRESSION OF STORMS OFF THE EASTERN
RIM AND WHITE MOUNTAINS MAKES IT THAT FAR WEST. OTHERWISE...THERE
WILL BE TOMORROW AS THE UPPER HIGH REMAINS CENTERED TO OUR NORTH.
UNTIL THEN...THE MAIN THREAT FROM STORMS TODAY WILL BE STRONG AND
DAMAGING WINDS.

UPPER HIGH PROGGED TO BE OVER NRN AZ/SRN UTAH REGION MON WITH NELY
MID-LEVEL FLOW OVER SE AZ. PATTERN FAVORABLE FOR CONVECTIVE
INITIATION VICINITY MOGOLLON RIM BY LATE MON MORNING OR EARLY MON
AFTERNOON WITH SHOWERS/THUNDERSTORMS EXPECTED TO MOVE SWWD MON
EVENING. QUASI-STATIONARY UPPER HIGH OVER THE GREAT BASIN THE
REMAINDER OF THE WEEK. THUS SEE NO REASON TO MAKE SIGNIFICANT
ADJUSTMENT TO INHERITED FORECASTS THAT REFLECT LOW-GRADE CONVECTIVE
ACTIVITY DURING THE TUE-SAT PERIOD. DAYTIME HIGH TEMPS EXPECTED TO
AVERAGE SLIGHTLY ABOVE NORMAL THROUGHOUT THIS FORECAST PERIOD.

&&

.FIRE WEATHER...HOT DAYTIME TEMPERATURES WILL OCCUR INTO THE MIDDLE
OF THIS WEEK. THUNDERSTORM COVERAGE IS EXPECTED TO INCREASE THIS
THIS EVENING AS DEEPER MOISTURE MOVES INTO THE AREA. GUSTY AND
ERRATIC WINDS WILL OCCUR VICINITY THUNDERSTORMS. ISOLATED TO
SCATTERED MAINLY AFTERNOON AND EVENING THUNDERSTORMS TO OCCUR DURING
THE UPCOMING WEEK AS HIGH PRESSURE ALOFT REMAINS OVER THE GREAT
BASIN.

&&

.AVIATION...HIGH-BASED THUNDERSTORMS WILL DEVELOP OVER THE HIGHER
TERRAIN THIS AFTERNOON AND MOVE WESTWARD INTO THE VALLEYS BY THIS
EVENING. MAIN CONCERN FOR THE TERMINAL SITES LATER THIS AFTERNOON
AND EVENING WILL BE WIND GUSTS OVER 35 KNOTS AND REDUCED
VISIBILITIES DUE TO BLOWING DUST. OTHERWISE SURFACE WINDS GENERALLY
EASTERLY 5-15 KTS TODAY...AND 10-20 KTS TONIGHT INTO MONDAY.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.
