AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
151 PM MST SUN JUN 28 2015

.SYNOPSIS...
THROUGH THIS WEEK...PERIODIC SHOWERS AND THUNDERSTORMS WILL BE
COMMON ACROSS THE MOUNTAINS OF SOUTHERN AND EASTERN ARIZONA. SEVERAL
EVENINGS WILL CARRY A SLIGHT CHANCE FOR THESE STORMS TO MOVE INTO
THE POPULATED LOWER DESERT AREAS. THE MOST LIKELY OUTCOME IN THOSE
AREAS WILL BE GUSTY WINDS AND SOME BLOWING DUST...BUT VERY LOCALIZED
BRIEF HEAVY RAIN WILL ALSO BE POSSIBLE. AFTERNOON TEMPERATURES WILL
REMAIN SLIGHTLY ABOVE NORMAL THOUGH BELOW THE EXCESSIVE LEVELS
EXPERIENCED THE PAST COUPLE WEEKS.

&&

.DISCUSSION...
AFTER A CLEAR MORNING ACROSS ARIZONA...CONVECTION IS QUICKLY
BLOSSOMING EARLY THIS AFTERNOON. THANKS TO THE INCREASED SUNSHINE
TEMPERATURES ARE RUNNING SEVERAL DEGREES ABOVE SAME TIME
YESTERDAY AND DEW POINTS DOWN JUST A LITTLE BIT. 28.12Z KTUS SOUNDING
STILL HAD VERY HIGH PWAT VALUES...ABOUT 1.4 IN AND NEAR RECORD HIGHS
FOR LATE JUNE. SOUTHEAST CALIFORNIA IS CAUGHT IN THE INCREASINGLY
MERIDIONAL FLOW BETWEEN THE GREAT BASIN HIGH AND AN OFF-SHORE LOW AND
THIS HAS HELPED KEEP TEMPERATURES THERE DOWN SEVERAL DEGREES.

FOR THE REST OF TODAY...HI-RES MODELS SHOWED MUCH MORE VARIABILITY IN
THEIR CONVECTIVE DEPICTION THOUGH OVERALL THERE WAS LESS ENTHUSIASM
FOR STRONG OUTFLOW WINDS INTO THE METRO AREA. THIS ISN/T TOO
SURPRISING GIVEN THE EXPECTED SLIGHT DECREASE IN INSTABILITY. THERE
WAS GENERAL AGREEMENT THAT WHAT OUTFLOWS DO FORM WILL MOVE IN
EARLIER...IN THE 3-6PM WINDOW. GIVEN THE QUICKLY THINNING BOUNDARY
LAYER MOISTURE THIS AFTERNOON...IT LOOKS LESS LIKELY THAT THE PHX
METRO AREA WILL SEE CONVECTION OF SUBSTANCE WITH ANY OUTFLOW /NOT TO
SAY A COUPLE OF SHOWERS POPPING OFF WONT HAPPEN/.

THE EASTERLY FLOW DOES SEEM AS IF IT/LL PUSH MORE STORMS ACROSS
SOUTHERN ARIZONA AND ALSO NORTHERN ARIZONA...WHICH MAY CAUSE OUTFLOWS
TO COLLIDE OVER WESTERN MARICOPA...YUMA...AND LA PAZ COUNTIES. THAT
AREA MAY SEE MORE SHOWERS/STORMS THIS EVENING. FURTHER WEST...BEYOND
PERHAPS A FEW SHOWERS EXPECTING IT TO REMAIN DRY UNDER THE MID/UPPER
LEVEL CLOUD CANOPY.

GREAT BASIN HIGH NOW APPEARS IT WILL BIFURCATE...WITH A CHUNK OF
ANOMALOUS TEMPS/HEIGHTS HEADING NORTH TOWARD ALASKA AND THE
REMAINDER SETTLING A BIT FURTHER SOUTH. THAT MEANS OVERALL WHAT WE
SEE TODAY IS GENERALLY WHAT WE/LL GET. REALLY HARD TO PICK OUT ANY
INDIVIDUAL DAY AS BEING MORE ACTIVE AT THIS POINT. CONCEIVABLE THAT
GILA...PINAL AND FAR EASTERN MARICOPA COUNTIES GET DAILY STORMS WHILE
PHOENIX WEST GETS LIMITED ACTIVITY /BESIDES SOME DUSTY WINDS/.
TEMPERATURES WILL NOT MODERATE MUCH AND REMAIN JUST ABOVE SEASONAL
NORMS.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
THUNDERSTORMS CURRENTLY ACROSS EASTERN ARIZONA WILL GRADUALLY MOVE
WEST THROUGH THE AFTERNOON AND EVENING. WHILE TS IS NOT EXPLICITLY
EXPECTED OVER KPHX...KSDL/KIWA COULD BE CLIPPED. ALL TERMINALS WILL
LIKELY BE IMPACTED BY OUTFLOW WINDS IN THE 22-02Z WINDOW.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
MID/UPPER LEVEL CLOUDS WILL NOT MOVE A GREAT DEAL OVER THE NEXT 24
HOURS. A FEW BRIEF SHOWERS WILL BE POSSIBLE BUT THE THREAT FOR TS IS
LOW.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
TUESDAY THROUGH SATURDAY...APPEARS WE ARE GOING TO BE IN A STAGNANT
PATTERN FOR MUCH OF THE WEEK...CHARACTERIZED BY SLIGHTLY ABOVE
NORMAL TEMPERATURES...DAILY MOUNTAIN THUNDERSTORMS MOVING FROM EAST
TO WEST...AND LOW DAYTIME HUMIDITY VALUES WITH GOOD OVERNIGHT
RECOVERY.

&&

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT WEATHER CONDITIONS
ACCORDING TO STANDARD OPERATING PROCEDURES.
