AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
330 PM MST MON JUL 14 2014
.UPDATE...UPDATED FIRE WEATHER DISCUSSION.
&&
.SYNOPSIS...
MONSOON MOISTURE WILL CONTINUE TO INCREASE ACROSS THE REGION THROUGH
TUESDAY...WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. COOLER
TEMPERATURES ARE ALSO FORECAST DUE TO CLOUDS...HUMIDITY...AND
RAINFALL. BY WEDNESDAY...A DRYING AND WARMING TREND IS FORECAST TO
CONTINUE INTO FRIDAY. INCREASED HUMIDITY AND A THREAT OF AFTERNOON
THUNDERSTORMS WILL RETURN MAINLY TO PORTIONS OF SOUTHWEST AND SOUTH
CENTRAL ARIZONA NEXT WEEKEND.
&&
.DISCUSSION...
MID AFTERNOON SATELLITE IMAGERY NOT LOOKING OVERLY PROMISING ACROSS
THE LOWER DESERTS. CU HAVE REPEATEDLY DEVELOPED AND DIED OFF SINCE
NOON AND THE METRO IS VIRTUALLY CLEAR OVERHEAD AS OF 22Z.
TEMPERATURES ALOFT AROUND 500 MB ARE JUST TOO WARM AND PROVIDING
ENOUGH OF A CAP TO INHIBIT CONVECTION. WHILE STORMS STILL HAVE A
GOOD CHANCE TO SURVIVE EAST OF PHOENIX NEAR GLOBE AND TO THE
SOUTHEAST OF THE METRO...THE LOWER DESERTS WILL STRUGGLE TO SEE
WIDESPREAD CONVECTION. GOING TO TRIM POPS SLIGHTLY INTO THE 15-20
PERCENT RANGE. COULD SEE STILL SEE SOME ISOLATED STORMS THAT PRODUCE
GUSTY WINDS AND HEAVY RAIN AROUND THE METRO.
MOISTURE WILL REMAIN IN PLACE ACROSS EASTERN ARIZONA ON TUESDAY
ALTHOUGH SOME DRY AIR WILL ALREADY START MOVING IN FROM THE WEST. AS
TUESDAY\S WEATHER WILL BE HEAVILY DEPENDENT UPON WHAT HAPPENS THIS
EVENING...MADE VERY FEW /IF ANY/ CHANGES TO THE POPS FOR TUESDAY.
MAINTAINING ELEVATED PRECIP CHANCES EAST OF THE COLORADO RIVER
VALLEY ALTHOUGH NOT AS HIGH AS TODAY\S VALUES.
&&
.PREVIOUS DISCUSSION...
TUESDAY...
IN THE UPPER LEVELS...BEHIND THE EXITING INVERTED TROF...MODELS
FORECAST UPPER LEVEL 300/250 MB HIGH CENTERS TO DEVELOP OVER
NORTHEAST AZ BY LATE TODAY...THEN SHIFT TOWARD FLAGSTAFF ON TUESDAY.
MONSOON RESEARCH HAS SHOWN WHEN 300/250 MB HIGH CENTERS
COINCIDE...SIGNIFICANT CONVECTION FAVORS THE EAST THROUGH SOUTH
FLANKS OF THE ANTI-CYCLONIC CIRCULATION. THEREFORE...LARGE
CONVECTIVE STORMS ARE EXPECTED OVER THE EASTERN RIM AND WHITE
MOUNTAINS THIS AFTERNOON. WESTERLY MOVING OUTFLOWS AND CONVECTION
BUILDING ALONG THE OUTFLOWS WILL HAVE A GOOD CHANCE OF DESCENDING
INTO THE LOWER CENTRAL DESERTS BY EVENING... INCLUDING PHOENIX AND
CASA GRANDE. THEREFORE EVENING PRECIP PROBABILITIES WILL BE ELEVATED
ON TUESDAY. AFTERNOON TEMPERATURES WILL ALSO BE COOLER DUE TO
INCREASED HUMIDITY AND CLOUDS.
WEDNESDAY THROUGH FRIDAY...
ALTHOUGH MODELS HAVE A DIFFICULT TIME MODELING THE LIGHT UPPER LEVEL
WIND REGIME DURING THE SUMMER-TIME...THIS FAR OUT THEY SUGGEST BROAD
QUASI-STABILIZING ANTICYCLONIC FLOW ALOFT OVER OUR FORECAST AREA. AT
THE SAME TIME...MODELS FORECAST A SIGNIFICANT DRYING TREND FROM THE
WEST...ALL RESULTING IN AN END TO CONVECTIVE ACTIVITY OVER THE
FORECAST AREA...WITH THE EXCEPTION OF ZONE 24 SOUTHERN GILA COUNTY
EAST OF PHOENIX WED THROUGH FRI.
SATURDAY AND SUNDAY...
MODELS FORECAST A RETURN OF MONSOON MOISTURE FROM MEXICO THIS
PERIOD. A FEW WEAK NORTHWARD UPPER LEVEL PERTURBATIONS FROM MEXICO
ARE POSSIBLE...AND ENOUGH TO INTRODUCE A SLIGHT CHANCE OF LATE
AFTERNOON/EVENING SHOWERS TO THE LOWER CENTRAL AZ DESERTS AND
MOUNTAINS FOR THE WEEKEND.
&&
.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...KSDL...
LATEST SATELLITE TRENDS SUGGEST THAT INHIBITION IN THE BOUNDARY
LAYER IS CURRENTLY HINDERING STORM DEVELOPMENT IN THE LOWER DESERTS.
HOWEVER...CONDITIONS STILL REMAIN MOIST AND FAVORABLE FOR CONVECTION
IN THE PHOENIX AREA EARLY THIS EVENING. ALTHOUGH ACTIVITY IS NOT
EXPECTED TO BE AS ORGANIZED AS THAT WHICH OCCURRED SUNDAY...ISOLATED
CELLS WITH AVIATION IMPACTS SUCH AS BRIEF GUSTY WINDS AND BLOWING
DUST ARE POSSIBLE...PARTICULARLY AT KIWA.
SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
AN AREA OF LOW PRESSURE ACROSS THE NORTHERN BAJA PENINSULA WILL
CONTINUE TO GENERATE ISOLATED CONVECTION THROUGH LATE THIS
AFTERNOON...MAINLY ACROSS NORTHERN IMPERIAL COUNTY. AT THE
TERMINALS...THERE IS A SLIGHT CHANCE OF A THUNDERSTORM OR GUST FRONT
AT KIPL THROUGH THIS EVENING BUT SOMEWHAT LESS LIKELY AT KBLH.
AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
&&
.FIRE WEATHER...
THURSDAY THROUGH MONDAY...
DRIER AIR WILL CONTINUE TO SPREAD EASTWARD THROUGHOUT MUCH OF CNTRL
ARIZONA THURSDAY/FRIDAY. DAYTIME HUMIDITIES OVER THE LOWER DESERTS
MAY FALL AS LOW AS 10 PERCENT WITH THE INTRODUCTION OF DRIER AIR
INTO THE REGION WITH GOOD RECOVERIES OVERNIGHT. THEREFORE...THE BEST
OPPORTUNITY FOR SHOWERS AND THUNDERSTORMS WILL BE RELEGATED BACK TO
THE HIGHER TERRAIN...INCLUDING GILA COUNTY...WITH LITTLE TO NO
CHANCE OF PRECIPITATION IN SOUTHEAST CALIFORNIA THROUGH THIS PERIOD.
WINDS WILL REMAIN RATHER LIGHT WITH ONLY OCCASIONAL AFTERNOON
GUSTS...THOUGH SOME STRONGER GUSTS WILL ACCOMPANY ANY AFTERNOON AND
EVENING THUNDERSTORMS IN GILA COUNTY. FORECAST MODELS INDICATE A
RETURN OF MONSOONAL MOISTURE BACK INTO THE REGION SOMETIME AFTER
SUNDAY...WITH SOME MINOR DIFFERENCES WHEN THE DEEPEST PROFILE WILL
BE OVER THE DISTRICTS.
