AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
819 AM MST WED JAN 6 2016

.SYNOPSIS...
SHOWERS WILL CONTINUE TO EXIT THE AREA TODAY...ALTHOUGH ANOTHER
WEATHER SYSTEM BRING PRECIPITATION TONIGHT AND THURSDAY WITH A
SIGNIFICANT DOWNTREND FRIDAY. A MUCH WEAKER WEATHER SYSTEM WILL BRING
A SLIGHT CHANCE OF SHOWERS SATURDAY NIGHT AND SUNDAY FOLLOWED BY DRY
CONDITIONS MONDAY AND TUESDAY.

&&

.DISCUSSION...
WATER VAPOR IMAGERY DEPICTS OUR SECOND STORM OF THE WEEK MOVING INTO
EASTERN ARIZONA...WITH RAPID DRYING AND WEAK SHORTWAVE RIDGING OVER
SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA. JUST A FEW SHOWERS
PERSIST EAST OF PHOENIX AS OF 15Z BUT THESE ARE DISSIPATING QUICKLY AND
ALL HI-RES SHORT TERM GUIDANCE INDICATE A MOSTLY DRY DAY THROUGH AT
LEAST LATE AFTERNOON. MADE SOME MINOR ADJUSTMENTS TO POPS TO KEEP AT
LEAST A SLIGHT CHANCE MENTION OF SHOWERS NORTH/EAST OF PHOENIX TODAY
/GIVEN UPSLOPE CONSIDERATIONS/. ELSEWHERE IT SHOULD BE DRY BEFORE THE
NEXT TROUGH APPROACHES FROM THE WEST LATE THIS AFTERNOON.

&&

.PREVIOUS DISCUSSION...
TONIGHT THROUGH FRIDAY... THE NEXT SYSTEM TO AFFECT US IS CENTERED
ROUGHLY NEAR 135W EARLY THIS MORNING. GOOD MODEL AGREEMENT THAT THERE
WILL BE THREE MAIN SHORT WAVES WITH THE UPPER TROUGH. THE FIRST ONE
MOVES INTO SOUTHEAST CALIFORNIA BY LATE THIS AFTERNOON AND IS MORE OF
A GLANCING BLOW FOR OUR AREA BUT HELPS TO RE-MOISTEN THE ATMOSPHERE.
THE SECOND MOVES THURSDAY MORNING AND HAS BETTER DYNAMICAL FORCING.
THE MAIN BRUNT OF IT LOOKS TO BE DONE BY 00Z SATURDAY...LINGERING
OVER THE HIGHER TERRAIN. THE THIRD ONE LOOKS TO BE QUITE WEAK AND
MOVES THROUGH EARLY FRIDAY. ADDED SLIGHT CHANCE OF THUNDER FOR
THURSDAY AND FRIDAY...FOR SIMILAR REASONS AS DISCUSSED ABOVE...THOUGH
FRIDAY THUNDERSTORM POTENTIAL WILL BE LIMITED TO EARLY AFTERNOON AND
CONFINED TO OUR EASTERNMOST AREAS.

ADDITIONAL QPF FOR TODAY THROUGH FRIDAY IS 0.10-0.25 LOWEST
DESERTS...0.50-1.00 PHOENIX AREA...1.00-1.75 MOUNTAINS. SNOW LEVELS
GRADUALLY DECLINE...MOST NOTABLY THURSDAY/THURSDAY NIGHT BOTTOMING
OUT AROUND 4000 FEET FRIDAY MORNING. STORM TOTAL SNOW ACCUMULATIONS
OF 1-2 INCHES POSSIBLE BELOW 5000 FEET AND 6-10 INCHES ABOVE 5500
FEET. VERY LITTLE TERRITORY AT THOSE ELEVATIONS IN OUR FORECAST AREA.

SATURDAY AND SUNDAY...
HEIGHTS RISE AS RIDGING RESTRENGTHENS OFFSHORE.
HOWEVER...GFS...ECMWF...AND GEM ALL DEPICT A TROUGH AND ASSOCIATED
COLD FRONT MAKING IT ASHORE OVER THE WEEKEND. EVEN THOUGH THE FEATURE
WEAKENS A LOT QUITE A BIT OF MOISTURE IS DEPICTED WITH
IT...ESPECIALLY GFS. GIVEN THE ABOVE AS WELL AS NAEFS ENSEMBLE
PROBABILITY TRENDS ASSOCIATED WITH THAT FEATURE...INTRODUCED SLIGHT
CHANCE POPS FOR SATURDAY NIGHT AND SUNDAY. THIS WILL ALSO HELP KEEP
HIGH TEMPS BELOW NORMAL.

MONDAY AND TUESDAY...
A RIDGE TRACKS ACROSS THE WESTERN STATES MONDAY AND TUESDAY FOR DRY
CONDITIONS AND A MODEST WARMING TREND.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...

SKIES WILL TEMPORARILY CLEAR OUT AFTER SUNRISE THIS MORNING LASTING
THROUGH AROUND 18Z BEFORE SOME DAYTIME CU REDEVELOPS. THE CU MAY
BECOME BROKEN AT TIMES WITH BASES BETWEEN 4-6K FEET. BREEZY WESTERLY
WINDS THIS MORNING WILL SUBSIDE SOMEWHAT INTO THE AFTERNOON AND THEN
EVENTUALLY TRANSITION TO AN UPSLOPE EASTERLY DIRECTION THIS EVENING.
ANOTHER LOW PRESSURE SYSTEM WILL BRING MORE RAIN AND LOW CIGS FOR THE
AREA STARTING AFTER 12Z THURSDAY.

SOUTHEAST CALIFORNIA/SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...

CLEAR TO MOSTLY CLEAR SKIES INTO THIS AFTERNOON WITH INCREASING
CLOUDS STARTING THIS EVENING AHEAD OF THE NEXT LOW PRESSURE SYSTEM.
MAY START TO SEE SOME SCATTERED SHOWERS STARING LATER THIS
EVENING...BUT CONFIDENCE IS NOT HIGH ENOUGH FOR ANYTHING BEYOND
VICINITY SHOWERS. WEST TO SOUTHWESTERLY WINDS TODAY WILL BE BREEZY AT
TIMES WITH SOME OCCASIONAL GUSTS TO 20 KTS.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
FRIDAY THROUGH TUESDAY...
RAIN CHANCES TAPER OFF FOR THE MOST PART STARTING FRIDAY...BUT THERE
WILL BE A SLIGHT CHANCE OF SHOWERS AGAIN MAINLY SATURDAY NIGHT INTO
SUNDAY AS A WEAK DISTURBANCE PASSES THROUGH THE REGION. HIGH PRESSURE
WILL SETTLE IN THEREAFTER ALLOWING FOR GRADUAL DRYING CONDITIONS.
HUMIDITY WILL BE MUCH ABOVE AVERAGE WITH MINIMUM VALUES NEAR 50
PERCENT INTO MONDAY WITH SLIGHTLY LOWER VALUES ON TUESDAY. EXPECT
BELOW NORMAL HIGH TEMPERATURES THROUGH THE PERIOD. WINDS SHOULD BE
LIGHT THROUGH THE ENTIRE PERIOD.
