AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
835 PM MST WED FEB 6 2013

.SYNOPSIS...
A GRADUAL COOLING TREND IS IN STORE...ESPECIALLY STARTING OVER THE
WEEKEND. ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS ARE EXPECTED
FOR THURSDAY...BEFORE A FAIRLY STRONG PACIFIC STORM DIVES SOUTH
TOWARDS ARIZONA. THIS WILL BRING BREEZY TO WINDY CONDITIONS ON
FRIDAY ALONG WITH A SLIGHT CHANCE OF RAIN AND MOUNTAIN SNOW SHOWERS
TO THE REGION FRIDAY EVENING THROUGH SATURDAY. MUCH COOLER
TEMPERATURES WILL MOVE IN STARTING SATURDAY LASTING THROUGH THE
MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...
A SERIES OF PACIFIC DISTURBANCES WILL CONTINUE TO MOVE INTO THE
SOUTHWEST U.S. THROUGH THE WEEKEND. THE FIRST MINOR SYSTEM WAS
MOVING THROUGH AZ THIS EVENING WITH EVEN A FEW LIGHTNING STRIKES
ALONG THE MOGOLLON RIM NORTH OF PAYSON AT 8 PM MST. A MODERATE
AMOUNT OF LOW LEVEL PACIFIC MOISTURE HAD ADVECTED INTO CENTRAL AND
SOUTHERN AZ LAST NIGHT AHEAD OF THE PACIFIC SHORTWAVE. THIS
SHORTWAVE FEATURE WILL MOVE OUT OF AZ LATE TONIGHT...SO FOR OUR
FORECAST AREA...EXCEPT FOR A FEW CU CLOUDS BASED NEAR 10 THSD
MSL...MOSTLY CLEAR SKIES ARE EXPECTED THROUGH THURSDAY MORNING.

THE NEXT IN THE SERIES OF PACIFIC TROFS WILL MOVE INTO SOUTHEAST CA
AND THE COLORADO RIVER VALLEY FRIDAY MORNING...THEN OVER SOUTH
CENTRAL AZ INCLUDING PHOENIX BY FRIDAY EVENING. A FAIRLY POWERFUL
COLD FRONT IS EXPECTED TO SWEEP THROUGH SOUTHEAST CA FRIDAY MORNING
WHICH IS REFLECTED IN THE VERY COLD 700 MB TEMPERATURES OF MINUS 10
TO MINUS 12 DEGREES C.  THE SHARP COLD FRONT HAS THE POTENTIAL TO
PRODUCE STRONG WINDS IN THE 35 TO 45 MPH RANGE ACROSS SOUTHEAST CA
AND THE COLORADO RIVER VALLEY FRIDAY MORNING AND AFTERNOON. THIS
POTENTIAL IS ALREADY HIGHLIGHTED IN THE CURRENT FORECASTS.  A WIND
ADVISORY WILL LIKELY BE ISSUED FOR THIS WIND POTENTIAL.

ALSO SINCE THE AIRMASS IS FORECAST TO BE VERY COLD...IT WILL LIKELY
SQUEEZE OUT AS MUCH OF THE MEAGER MOISTURE THAT IS AVAILABLE FOR
LIGHT SHOWER AND/OR SPRINKLE POTENTIAL AREA-WIDE FRIDAY THROUGH THE
WEEKEND. THIS LARGE COLD PACIFIC WEATHER SYSTEM BECOMES STATIONARY
OVER AZ THROUGH THE WEEKEND. A SLIGHT CHANCE OF SHOWERS IS ALSO IN
THE FORECAST.

ADDITIONALLY...700 MB TEMPERATURES OF MINUS 10 TO MINUS 12 DEGREES C
SETTLING OVER THE REGION SAT AND SUN NORMALLY PORTEND NEAR WIDE-
SPREAD FREEZING MORNING TEMPERATURES. HOWEVER...WITH MID LEVEL
MOISTURE EXPECTED TO CIRCULATE AROUND THE STATIONARY LOW PRESSURE
SYSTEM...THE COLD FREEZE POTENTIAL WILL LIKELY BE NEGATED.
HOWEVER...SOME DESERT TEMPERATURES WILL LIKELY FALL INTO THE MID 30S
SUN AND MON MORNINGS.

CURRENT FORECASTS LOOK OK FOR NOW. PREVIOUS DISCUSSION BELOW STILL
APPLIES.

PREVIOUS DISCUSSION...
MID AND HIGH CLOUDS ARE QUICKLY EXITING TO THE EAST THIS AFTERNOON
WHILE SCATTERED DAYTIME CUMULUS AFFECTS MAINLY HIGHER TERRAIN AREAS
EAST OF PHOENIX. THESE CLOUDS ARE ASSOCIATED WITH A DRY SHORTWAVE
TROUGH MOVING THROUGH THE REGION WHICH IS ALSO LOWER HEIGHTS AND
TEMPERATURES SLIGHTLY. BRIEF RIDGING WILL DOMINATE ON THURSDAY WITH
MOSTLY CLEAR SKIES AND CONTINUED ABOVE NORMAL TEMPERATURES.
HOWEVER...THIS WILL BE SHORT-LIVED AS A STRONG PACIFIC TROUGH
CURRENTLY OFF THE PACIFIC NORTHWEST COAST DIVES SOUTH SOUTHEAST INTO
CALIFORNIA FRIDAY MORNING. THERE CONTINUES TO BE GOOD MODEL
AGREEMENT WITH THIS UPCOMING SYSTEM AT LEAST THROUGH SATURDAY. THE
MAIN SHORTWAVE TROUGH IS PROGGED TO SWEEP INTO SOUTHEAST CALIFORNIA
FRIDAY MORNING AND THEN BRIEFLY SLOW DOWN AS THE UPPER LOW DEEPENS
OVER THE GREAT BASIN.

WILL SEE A FIRST INITIAL COLD FRONT MOVE THROUGH SOUTHEAST
CALIFORNIA EARLY FRIDAY MORNING BEFORE GRADUALLY WEAKENING AS IT
MOVES INTO SOUTH-CENTRAL ARIZONA FRIDAY AFTERNOON. MOISTURE WILL BE
A LIMITING FACTOR THROUGH THE ENTIRE PROGRESSION OF THE SYSTEM AS IT
STAYS FAR REMOVED FROM ALL SUBTROPICAL MOISTURE AND WITH THE LAND
TRACK OF THE SYSTEM. FORECAST PWATS ARE ON THE LOW SIDE...MAINLY
AROUND A THIRD OF AN INCH. THE PV ANOMALY WILL STILL BE WELL REMOVED
TO THE WEST DURING THE DAYTIME HOURS FRIDAY...SO ONLY SLIGHT CHANCE
POPS DEPICTED ACROSS HIGHER TERRAIN AREAS OF SOUTHEAST CALIFORNIA.

THE MAIN FORECAST CONCERN ON FRIDAY WILL BE THE POTENTIAL FOR NEAR
WIND ADVISORY CONDITIONS ACROSS SOUTHEAST CALIFORNIA. BY 12Z
FRIDAY...MODELS SHOW 15-18DM 12HR 500MB HEIGHT FALLS JUST EAST OF
LOS ANGELES. THIS MAXIMIZED AREA OF HEIGHT FALLS WILL SKIRT BY TO
THE NORTH OF OUR FORECAST AREA DURING THE DAY ON FRIDAY...BUT SHOULD
STILL SEE 12HR HEIGHT FALLS OF 10-12DM ACROSS SOUTHEAST CALIFORNIA.
COLD AIR ADVECTION BEHIND THE ADVANCING COLD FRONT ALONG WITH STRONG
925MB WESTERLY WINDS OF 25-35KT SHOULD GIVE RISE TO NEAR OR LOW END
WIND ADVISORY CONDITIONS ON FRIDAY. HIGH TERRAIN AREAS OF CENTRAL
RIVERSIDE COUNTY AND MUCH OF IMPERIAL COUNTY WILL LIKELY SEE THE
BRUNT OF THE WINDS.

BY FRIDAY EVENING...THE MAIN PV ANOMALY WILL FINALLY SWING THROUGH
SOUTHEAST CALIFORNIA. THE MAIN FORCING AND BEST PRECIPITATION
CHANCES WILL BE WITH PROGRESSION OF THE PV ANOMALY ACROSS THE REGION
FRIDAY NIGHT INTO SATURDAY MORNING. DUE TO THE EXPECTED LIMITED
MOISTURE...SHOULD ONLY SEE WIDELY SCATTERED SHOWERS ACROSS SOUTHEAST
CALIFORNIA AND SOUTHWEST ARIZONA FRIDAY EVENING THROUGH THE EARLY
OVERNIGHT HOURS. AREAS ACROSS SOUTH-CENTRAL ARIZONA WILL MAINLY SEE
SCATTERED SHOWERS AFTER MIDNIGHT WITH BEST CHANCES ACROSS HIGHER
TERRAIN AREAS NORTH AND EAST OF PHOENIX IN AREAS OF ENHANCED UPSLOPE
FORCING. SNOW LEVELS WILL DROP TO AROUND 4K FEET SATURDAY
MORNING...BUT PRECIPITATION WILL BE WINDING DOWN...SO ONLY EXPECTING
MEASURABLE SNOWFALL OVER THE HIGHEST PEAKS.

COLD AIR AND A LINGERING TROUGH PATTERN WILL SETTLE IN ACROSS THE
REGION INTO EARLY NEXT WEEK. A SECOND SHORTWAVE TROUGH WILL
REINFORCE THE LONGWAVE TROUGH AS IT DIVES SOUTHWARD THROUGH THE
GREAT BASIN ON SUNDAY INTO THE DESERT SOUTHWEST ON SUNDAY NIGHT.
THERE IS STILL QUITE A BIT OF UNCERTAINTY WITH THE POSITIONING OF
SECOND SHORTWAVE...BUT SHOULD AT LEAST GIVE RISE TO A LINGERING
SLIGHT CHANCE OF PRECIPITATION MAINLY ACROSS HIGHER TERRAIN AREAS OF
SOUTH-CENTRAL ARIZONA SUNDAY AND MONDAY. OF MORE CERTAINTY IS THE
CONTINUED COLD AIR IN PLACE AND WELL BELOW NORMAL TEMPERATURES
LIKELY EXTENDING THROUGH THE MIDDLE OF NEXT WEEK. OVERNIGHT LOWS
COULD DIP TO AROUND FREEZING OR EVEN SLIGHTLY BELOW IN RURAL LOWER
DESERT LOCATIONS STARTING SATURDAY NIGHT. AT THIS POINT NOT
EXPECTING FREEZING TEMPERATURES TO AFFECT A LARGE ENOUGH AREA TO
WORRY ABOUT FUTURE FREEZE HEADLINES...BUT WILL CONTINUE TO MONITOR
THE LATEST GUIDANCE OVER THE NEXT SEVERAL DAYS FOR THE POSSIBILITY.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA...INCLUDING KPHX...KIWA...KSDL...
THROUGH 18Z THU...FEW CU NEAR 10 THSD MSL. LIGHT WIND.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
THROUGH 18Z THU...MOSTLY CLEAR. LIGHT WIND.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
FRIDAY THROUGH TUESDAY...
LARGE AREA OF PACIFIC LOW PRESSURE WILL BEGIN TO DROP SOUTH INTO THE
REGION...GENERATING WIDESPREAD CLOUDINESS...BREEZY TO WINDY
CONDITIONS AREAWIDE AND A MODEST COOLING TREND FOR THE WEEKEND. THE
STRONGEST WINDS ARE EXPECTED TO EXPAND FROM SOUTHEAST CALIFORNIA
ACROSS THE SOUTHWEST ARIZONA DESERTS. AS TEMPERATURES COOL WITH THE
ARRIVAL OF THIS SYSTEM...HUMIDITIES REMAIN HIGH ENOUGH THAT CRITICAL
FIRE WEATHER CONDITIONS ARE NOT ANTICIPATED AT THIS TIME. A SLIGHT
CHANCE OF MOSTLY LIGHT SHOWERS WILL EXPAND FROM WEST TO EAST LATE
FRIDAY...ENDING OVER SOUTHEAST CALIFORNIA BY SATURDAY NIGHT AND OVER
SOUTHERN ARIZONA SUNDAY NIGHT. TEMPERATURES TAKE A TUMBLE FROM THEIR
ABOVE NORMAL READINGS EARLIER IN THE WEEK...WITH POTENTIAL FOR
FREEZING MORNING LOWS IN THE OUTLYING DESERT AREAS AND DAYTIME HIGHS
STRUGGLING TO WARM INTO THE 60S FOR THE LOWER DESERTS. FORECAST
MODELS INDICATE THIS SYSTEM MAY LINGER THROUGH EARLY NEXT
WEEK...KEEPING COOL BUT MOSTLY DRY CONDITIONS FOR THE FIRE
DISTRICTS.
