AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE TUCSON AZ
230 PM MST SUN AUG 18 2013

.SYNOPSIS...AN UPPER LEVEL RIDGE WILL REMAIN CENTERED OVER THE
REGION THROUGH AROUND TUESDAY...THEN IT WILL BEGIN TO WEAKEN AND
SHIFT TO THE EAST. THE PRESENCE OF THIS HIGH WILL MAINTAIN ABOVE
AVERAGE AFTERNOON TEMPERATURES MOST OF THIS WEEK. WE WILL CONTINUE
TO SEE ENOUGH MOISTURE FOR A CHANCE OF MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS.

&&

.DISCUSSION...IT WAS ANOTHER RECORD BREAKING DAY FOR TUCSON AIRPORT
WITH A HIGH OF 107 DEGREES. THIS MARKS THE 3RD DAY IN A ROW WITH
TEMPERATURES AT 107 OR HIGHER. SCATTERED SHOWERS AND THUNDERSTORMS
QUICKLY DEVELOPED ACROSS CENTRAL PORTIONS OF THE FORECAST AREA
MIDDAY AND HAVE CONTINUED THROUGH THE EARLY AFTERNOON. LATEST KEMX
RADAR IMAGERY SHOWS THESE STORMS NOW MAINLY EAST OF SELLS WITH THE
HIGHEST CONCENTRATION FROM SASABE TO MARANA. EXPECT THESE SCATTERED
STORMS TO CONTINUE INTO THE EARLY EVENING HOURS WITH THE MAIN THREAT
BEING STRONG AND GUSTY WINDS WHICH WILL ALSO BE CAPABLE OF PRODUCING
BLOWING DUST ESPECIALLY NORTH AND WEST OF TUCSON. LOCALIZED HEAVY
DOWNPOURS WILL ALSO OCCUR WITH THESE STORMS. THE STORMS SHOULD
GENERALLY TAPER OFF DURING THE EVENING HOURS BUT CAN'T RULE OUT A
FEW LINGERING SHOWERS AND STORMS OVERNIGHT.

MEANWHILE...SOUTHERLY FLOW WILL CONTINUE THROUGH THE EARLY PART OF
THIS WEEK AS HIGH PRESSURE ALOFT REMAINS CENTERED NEAR THE AZ/NM
BORDER. WITH CONTINUED SOUTHERLY FLOW AND AMPLE MOISTURE...EXPECT A
CONTINUED LOW TO MID GRADE MONSOON PATTERN. FOR THE SECOND HALF OF
THE WEEK...THE HIGH IS PROGGED TO SHIFT EAST WITH THE FLOW BECOMING
MORE EASTERLY. THE LATEST MODEL RUNS ARE SHOWING SLIGHTLY DRIER AIR
ADVECTING IN WHICH WOULD RESULT IN MORE OF A LOW GRADE MONSOON
PATTERN. HAVE KEPT POPS GENERALLY IN THE SLIGHT CHANCE TO LOW END
CHANCE RANGE THIS WEEK...WITH THE USUAL DAY TO DAY VARIABILITY
EXPECTED. BY NEXT WEEKEND WE'RE WATCHING A POSSIBLE SYSTEM MOVING UP
THE COAST OF BAJA WHICH COULD BRING A RESURGENCE IN MONSOON STORMS.
STAY TUNED. OTHERWISE...TEMPERATURES WILL REMAIN WELL ABOVE NORMAL
EARLY THIS WEEK WITH GRADUAL COOLING TO NEAR NORMAL NEXT WEEKEND.

&&

.AVIATION...SCT-BKN CLOUDS 8-12K FT AGL WILL CONTINUE THRU ABOUT
19/06Z WITH LINGERING SCT-BKN DEBRIS CLOUDINESS AOA 15K FT AGL INTO
MONDAY MORNING.SCT -SHRA AND -TSRA WILL CONTINUE THRU ABOUT 19/06Z
THEN TAPER OFF THEREAFTER. SURFACE WINDS ERRATIC AND GUSTY NEAR
TSRA'S...OTHERWISE NORMAL DIURNAL TRENDS ARE EXPECTED.  AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...AN UPPER LEVEL HIGH PRESSURE OVER THE AREA WILL
RESULT IN ABOVE NORMAL TEMPERATURES. THERE WILL BE AMPLE MOISTURE
FOR ISOLATED TO SCATTERED AFTERNOON AND EVENING THUNDERSTORMS
THROUGH MUCH OF THIS WEEK. TEMPERATURES WILL COOL SLIGHTLY LATE THIS
WEEK BUT WILL REMAIN ABOVE NORMAL UNTIL NEXT WEEKEND. NORMAL DIURNAL
WIND TRENDS ARE EXPECTED THIS WEEK...WITH STRONG GUSTY WINDS
POSSIBLE IN THE VICINITY OF THUNDERSTORMS.  IT IS LOOKING INCREASING
LIKELY THAT MOISTURE WILL INCREASE FROM THE SOUTH LATE NEXT WEEKEND
RESULTING IN A DECENT UPTICK IN CONVECTION.
