AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
846 AM MST WED JUN 24 2015

.SYNOPSIS...AS THE MOISTURE CONTINUES TO INCREASE...THE CHANCE OF
SHOWERS AND THUNDERSTORMS WILL GREATLY INCREASE TODAY. SOME STORMS
TODAY WILL GENERATE STRONG WINDS WITH AREAS OF BLOWING DUST
POSSIBLE. A CHANCE OF SHOWERS AND THUNDERSTORMS WILL THEN CONTINUE
INTO NEXT WEEK...WITH THE WEEKEND SHAPING UP FOR A BUSY THUNDERSTORM
PERIOD. AS THIS HAPPENS...DAYTIME TEMPERATURES WILL MODERATE CLOSER
TO SEASONAL NORMALS.

&&

.DISCUSSION...LATEST IR/WV IMAGERY SHOWS MOSTLY CLEAR SKIES ACROSS
MUCH OF SOUTHEAST ARIZONA WITH SOME LEFTOVER DEBRIS CLOUDINESS
MAINLY ACROSS THE TOHONO OODHAM NATION. THE INVERTED TROUGH THAT
WE'VE BEEN WATCHING OVER THE PAST FEW DAYS IS NOW LOCATED OVER
CHIHUAHUA WITH NORTHEAST STEERING FLOW BETWEEN THIS FEATURE AND THE
HIGH PRESSURE RIDGING ACROSS NORTHERN ARIZONA INTO THE FOUR CORNERS
REGION. 12Z KTWC SOUDNING WAS STILL FAIRLY DRY WITH PWAT VALUES
UNDER 1 INCH. HOWEVER...LATEST SURFACE OBSERVATIONS AND MODEL DATA
ARE ALL DEPICTING CONSIDERABLE MOISTENING OVER THE PAST COUPLE OF
HOURS. THE TUCSON AREA REMAINS ON THE EDGE OF THE MOISTURE BUT WE
ARE SEEING LOWER LEVELS MOISTEN IN THE TUCSON METRO WITH SURFACE
DEWPOINTS IN THE 40S AND THE 50S WITH 50S TO EVEN SOME LOWER 60S
ACROSS GRAHAM/GREENLEE/COCHISE COUNTIES.

IN TERMS OF CONVECTIVE DEVELOPMENT TODAY...WE EXPECT A FAIRLY EARLY
START ALONG A LOWER LEVEL CONVERGENCE ZONE...INITIALLY  ACROSS CENTRAL
PORTIONS OF THE AREA FROM EASTERN PIMA COUNTY INCLUDING THE TUCSON
METRO AREA AND ADJACENT CATALINA/RINCON MOUNTAINS SOUTHWARD INTO
THE SANTA RITA MOUNTAINS AND SANTA CRUZ COUNTY. WITH THE STRONG
INVERTED-V PROFILES THE MAIN THREAT WILL BE STRONG GUSTY WINDS AND
BLOWING DUST PUSHING MAINLY TO THE WEST. RAINFALL AMOUNTS WILL
GENERALLY BE LESS THAN ONE HALF OF AN INCH IN VALLEYS  WITH THE
MAJORITY OF VALLEY LOCATIONS FROM TUCSON WESTWARD SEEING PRIMARILY
WIND IMPACTS. SOME HIGHER RAINFALL AMOUNTS ARE POSSIBLE IN THE
MOUNTAINS. MEANWHILE...WE ALSO EXPECT DEVELOPMENT ACROSS THE WHITE
MOUNTAINS THIS AFTERNOON WHICH WILL PUSH TO THE SOUTHWEST AND LIKELY
RESULT IN GUSTY OUTFLOW WINDS MAINLY ACROSS PINAL COUNTY INTO THIS
EVENING. LATEST FORECAST HAS THIS SCENARIO COVERED WELL SO NO
UPDATES THIS MORNING.

&&

.AVIATION...VALID THROUGH 25/18Z. MOSTLY CLEAR THIS MORNING WITH
DEBRIS CLOUDS CLEARING. HOWEVER...SCT-BKN CLOUDS ABOVE 7-9KFT AGL
WILL INCREASE STARTING AFTER 24/18Z WITH SCT TSRA COVERAGE EXPECTED
THIS AFTERNOON AND EVENING...AFFECTING MUCH OF SE AZ AFTER 24/19Z.
STRONG GUSTY OUTFLOW WINDS OF 40-50 KTS WILL BE POSSIBLE IN AND NEAR
THUNDERSTORMS ALONG WITH RELATIVELY BRIEF MVFR CONDITIONS. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...MONSOONAL MOISTURE WILL BE DIRECTED INTO SOUTHEAST
ARIZONA FOR THE NEXT SEVERAL DAYS WITH THUNDERSTORM ACTIVITY
CONTINUING TO RAMP UP THROUGH THE WEEKEND.  COVERAGE OF STORMS WILL
SPREAD WESTWARD EACH AFTERNOON THROUGH REST OF THE WEEK.  INITIAL
THREAT FROM THUNDERSTORMS WILL BE STRONG GUSTY OUTFLOWS AND DRY
LIGHTNING THROUGH WEDNESDAY UNTIL MOISTURE BECOMES MORE ENTRENCHED.
WIND GUSTS OF 35-45 MPH WILL BE FAIRLY COMMON WITH THE POTENTIAL FOR
THE STRONGEST AFTERNOON AND EARLY EVENING STORMS TO PRODUCE WINDS IN
EXCESS OF 50 MPH.

EASTERLY WINDS CURRENTLY OVER MUCH OF ZONE 152 WILL CONTINUE THROUGH
TODAY AND THURSDAY. WINDS WILL SWING BACK AROUND TO A NORTHWESTERLY
DIRECTION ON FRIDAY. SATURDAY THROUGH MONDAY...WINDS WILL BE
EASTERLY/SOUTHEASTERLY DURING THE AFTERNOON.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...NONE.
