AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
955 PM MST THU APR 23 2015

.SYNOPSIS...
A SERIES OF PACIFIC WEATHER DISTURBANCES WILL MOVE THROUGH THE
REGION THROUGH SUNDAY...RESULTING IN OFF AND ON CHANCES OF RAIN AS
WELL AS BELOW NORMAL TEMPERATURES. BREEZY TO WINDY CONDITIONS ARE
ANTICIPATED SATURDAY AFTERNOON INTO MONDAY. A MUCH DRIER AND WARMER
AIRMASS WITH RETURN TO THE REGION MONDAY THROUGH WEDNESDAY. NEAR 100
DEGREE TEMPERATURES ARE POSSIBLE ON THE WARMEST SOUTHWEST DESERTS
NEXT WEDNESDAY AND THURSDAY.

&&

.DISCUSSION...
TONIGHT AND FRIDAY...
IR/WATER VAPOR SATELLITE IMAGERY SHOWS THE UPPER LEVEL LOW MOVING
EAST OVER THE SOUTHWEST STATES THIS EVENING...THE TROUGH AXIS
CURRENTLY OVER THE LOWER COLORADO RIVER VALLEY. EARLIER THIS EVENING
THERE WERE WIDELY SCATTERED SHOWERS AND THUNDERSTORMS THAT FORMED
NEAR IMPERIAL AND CALEXICO IN SOUTHEAST CALIFORNIA...THE STORMS
GRADUALLY MOVED NORTHWARD ALONG THE LOWER COLORADO RIVER VALLEY
TOWARD BLYTHE...WITH SOME ISOLATED ACTIVITY IN YUMA AND LA PAZ
COUNTIES AS WELL. THE STORM ACTIVITY HAS SINCE DIMINISHED WITH THE
LOSS OF DAYTIME HEATING/INSOLATION. HI-RES MODELS/HRRR AND WRF HAVE
PRETTY MUCH CAPTURED THIS CONVECTIVE TREND...SHOWING VERY LITTLE
ACTIVITY OVER MOST OF OUR FORECAST AREA UNTIL AROUND 11Z FRIDAY
MORNING...THEN SOME ISOLATED SHOWERS ARE POSSIBLE OVER SOUTHERN GILA
COUNTY OFF AND ON THROUGH THE MORNING HOURS. THE  GFS/ECMWF QUICKLY
MOVE THE TROUGH AXIS ACROSS SOUTH-CENTRAL ARIZONA TONIGHT...AND THEN
EAST INTO NEW MEXICO BY FRIDAY AFTERNOON...SO STILL NOT LOOKING AT
PARTICULARLY HIGH PROBABILITIES OF MEASURABLE PRECIP NOR A LOT IN
THE WAY OF ACCUMULATIONS IF WE DO GET RAIN. BASED ON THE OBSERVATION
AND MODEL TRENDS...CUT BACK ON THE POPS FOR MOST OF OUR LOWER DESERT
ZONE/SOUTHEAST CALIFORNIA AND SOUTHWEST AZ THROUGH FRIDAY
MORNING...JUST KEEPING LINGERING SLIGHT CHANCES AT BEST. WITH THE
CLOUDS AND ISOLATED SHOWERS...TEMPERATURES FRIDAY WILL BE
COOLER...IN THE UPPER 70S TO LOW 80S OVER THE LOWER DESERTS. OUTSIDE
OF THE SHORT TERM REDUCTIONS TO POPS FOR TONIGHT...THE FORECAST
LOOKS TO BE ON TRACK FOR THE WEEKEND INTO EARLY NEXT WEEK.

PREVIOUS DISCUSSION...
SATURDAY AND SUNDAY...
TEMPS DECREASE SOME MORE...DIPPING BELOW NORMAL. WE WILL BE BETWEEN
SYSTEMS SATURDAY WITH ONLY SLIGHT WARMING. ANOTHER TROUGH...THIS
TIME FROM THE NORTH...PUSHES SOUTHWARD THROUGH THE DESERTS SATURDAY
NIGHT AND SUNDAY. THE TRAJECTORY OF THIS SYSTEM IS NOT IDEAL FOR
MOISTURE CONTENT. HOWEVER...IT IS COLDER AND STRONGER AND WILL BE
ABLE TO WORK WITH LEFTOVER MOISTURE FOR ANOTHER PRECIP
OPPORTUNITY...MAINLY OVER OUR EASTERN AREAS WHICH INCLUDES METRO
PHOENIX. WINDS WILL BE SIGNIFICANTLY STRONGER AS WELL BEGINNING
SATURDAY AFTERNOON AND CONTINUING INTO MONDAY...ESPECIALLY OVER
SOUTHEAST CALIFORNIA AND THE LOWER COLORADO RIVER VALLEY.

MONDAY THROUGH THURSDAY...DRY NORTHERLY FLOW MONDAY...FOLLOWED BY A
BUILDING RIDGE AND MUCH WARMER TEMPERATURES WILL PRECLUDE ANY SHOWER
ACTIVITY ACROSS THE FORECAST AREA. AFTERNOON TEMPERATURES ON SOME
SOUTHWEST DESERT LOCATIONS WEDNESDAY SHOULD APPROACH 100 DEGREES.

&&

.AVIATION...

SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
UPPER LEVEL TROUGH WILL CONTINUE TO MOVE EAST THROUGH FRIDAY. STILL
LOOKING AT AN ISOLATED SHOWER OR TWO THAT COULD POP UP OVER THE
LOWER DESERTS OVERNIGHT. SHOWER ACTIVITY EXPECTED TO INCREASE IN
COVERAGE EAST OF PHOENIX AFTER 11Z FRIDAY. JUST ENOUGH INSTABILITY
WITH DAYTIME HEATING FOR AN ISOLATED THUNDERSTORM TO FORM NEAR THE
TERMINALS BY EARLY FRIDAY AFTERNOON. SCT-BKN CLOUD DECKS AOA 8KFT
SHOULD CLEAR OUT BY THE EVENING/AFTER 01Z SATURDAY. OVERALL LIGHT
WINDS GENERALLY LESS THAN 10-12KT...GUSTY NEAR SHOWERS OR
THUNDERSTORMS.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
FEW-SCT HIGH CLOUDS FROM 11Z FRIDAY MORNING ONWARD. EXPECT LIGHT
WINDS OVERNIGHT ACROSS THE AREA. SURFACE WINDS REMAIN ELEVATED AT
KIPL THROUGH 09Z FRIDAY...THEN INCREASE WITH GUSTS UP TO 25KT DURING
THE AFTERNOON.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER... SUNDAY THROUGH THURSDAY... A POTENT UPPER TROUGH
WILL MOVE THROUGH THE AREA ON SUNDAY AND BRING ELEVATED WINDS TO THE
AREA ALONG WITH A PERIOD OF ELEVATED HUMIDITIES. FOLLOWING THE
DEPARTURE OF THE TROUGH SUNDAY NIGHT/MONDAY...DRY AIR WILL MOVE INTO
THE REGION AND TEMPERATURES WILL INCREASE. THIS WILL RESULT IN
SINGLE DIGIT AFTERNOON HUMIDITIES WITH FAIR OVERNIGHT RECOVERIES.
WINDS FROM MONDAY ONWARD WILL BE LIGHT AND WILL FOLLOW TYPICAL
DIURNAL TRENDS.
