AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
905 AM MST SUN DEC 8 2013

.SYNOPSIS...
A LARGE COLD LOW PRESSURE SYSTEM ACROSS THE WESTERN STATES WILL ONLY
SLOWLY MOVE EAST THIS WEEK. A VERY WEAK WEATHER DISTURBANCE WILL
BRING MORE CLOUDS AND A SLIGHT CHANCE OF SHOWERS TO THE MOUNTAINS OF
EASTERN ARIZONA LATE TONIGHT AND EARLY MONDAY. OTHERWISE...CLEARING
SKIES WITH COLD OVERNIGHT TEMPERATURES CAN BE EXPECTED LEADING TO
THE THREAT OF FREEZING TEMPERATURES ACROSS THE AREA THROUGH TUESDAY
MORNING. A WARMING TREND IS EXPECTED FROM MID WEEK INTO THE WEEKEND.

&&

DISCUSSION...
THE SHORTWAVE RESPONSIBLE FOR THE VERY LIGHT SHOWERS ACROSS THE
EASTERN PARTS OF THE FORECAST AREA OVERNIGHT WAS QUICKLY EXITING
WELL NORTHEAST OF THE REGION THIS MORNING. STRATO-CU LAYER FROM
PHOENIX EASTWARD HAS BEEN HOLDING TOGETHER WITH ENOUGH RESIDUAL
MOISTURE AND WAA AROUND THE H8 LEVEL...THOUGH MODELS SUGGEST A
GRADUAL EROSION OF THIS CLOUD DECK THROUGH THE EARLY AFTERNOON.
HOWEVER...SATELLITE IMAGERY CLEARLY SHOWS UPSTREAM MID/UPPER LEVEL
MOISTURE ADVECTING EASTWARD...ARRIVING INTO THE CWA THIS EVENING.
MADE SOME ADJUSTMENTS TO SKY COVER...AS WELL AS HOURLY TEMPERATURE
TRACES WITH A WIDE SPREAD BETWEEN AREAS OF CLEAR SKIES AND OVERCAST
EVENTUALLY NORMALIZING LATER THIS AFTERNOON. OTHERWISE...WILL BE
ANALYZING MODEL LOW TEMPERATURE FORECAST FOR THE NEXT 2 MORNINGS
WITH THE EXPECTATION OF AT LEAST AREAS OF FREEZING WEATHER.

&&

.PREVIOUS DISCUSSION...
TODAY THROUGH MONDAY...
ALTHOUGH SOUTHEAST CA AND SOUTHWEST AZ WILL BE MOSTLY CLEAR TODAY...
A FEW SHOWERS WILL LINGER OVER PORTIONS OF SOUTH CENTRAL AZ THIS
MORNING...GENERALLY FROM PHOENIX NORTH THROUGH EAST. CLEARING SKIES
ARE EXPECTED THIS AFTERNOON.

A SECOND SHORTWAVE TROF IS FORECAST TO APPROACH AZ FROM THE
NORTHWEST BY EVENING...THEN MOVE ACROSS THE STATE ON MONDAY.
ALTHOUGH THE MASS FIELDS FORECAST BY THE GFS AND EURO MODELS LOOK
SIMILAR WITH THIS SECOND SHORTWAVE TONIGHT AND MONDAY...DIFFERENCES
EMERGE REGARDING THE EXTENT OF THE MOISTURE FIELDS. THE GFS HAS
MODELED ENOUGH MOISTURE FOR A FEW SHOWERS IN SOUTHERN AZ SUNDAY
NIGHT AND MONDAY...WHILE THE EUROPEAN MODEL IS RELATIVELY DRY...BUT
WITH CONSIDERABLE MID AND HIGH CLOUDS. FOR NOW ALL AZ OFFICES HAVE
DECIDED TO FORECAST A THREAT OF SHOWERS OVER THE HIGHER TERRAIN OF
EASTERN AZ...INCLUDING OUR PORTIONS OF SOUTHERN GILA COUNTY EAST OF
GLOBE MIAMI. CONSIDERABLE MID/HIGH CLOUDS SHOULD HOWEVER MODERATE
MONDAY MORNING TEMPERATURES AREA-WIDE.

TUESDAY THROUGH SUNDAY...
WITH CLEARING SKIES AND DRIER AIR EXPECTED FROM THE NORTH MONDAY
NIGHT...TUESDAY MORNING TEMPERATURES HAVE THE POTENTIAL TO DROP INTO
THE UPPER 20S TO MID 30S ON THE LOWER DESERTS. COMPLICATING THESE
POTENTIALLY COLD READINGS ARE PERIODIC NORTHEAST BREEZES THAT ARE
FORECAST TO DEVELOP MONDAY NIGHT AND TUESDAY MORNING. IF NO WIND
WERE FORECAST...TEMPERATURES TUESDAY MORNING WOULD QUALIFY AS A
MARGINAL FREEZE WARNING EVENT ON THE DESERTS FROM SOUTHEAST CA TO
SOUTH CENTRAL ARIZONA.

OTHERWISE...MOSTLY CLEAR SKIES WITH GRADUALLY WARMER TEMPERATURES
ARE EXPECTED FROM WED THROUGH SUN. MUCH WARMER AFTERNOON TEMPS ARE
EXPECTED SATURDAY AND SUNDAY WHICH SHOULD EXCEED NORMAL VALUES BY A
FEW DEGREES.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA...INCLUDING KPHX...KIWA...AND KSDL...FRONTAL
BAND CLOUDINESS WITH BASES OF 6-8 KFT MSL OVER SOUTH-CENTRAL ARIZONA
W...INCLUDING METRO PHOENIX...WILL BEGIN TO DECREASE FROM WEST TO
EAST AFTER 14Z. HIGHER MOUNTAIN TOPS WILL BE OBSCURED. AFTER LOWER
CLOUDS DISSIPATE...HIGHER CLOUDS WILL BE ON THE INCREASE AS A
FOLLOW-ON DISTURBANCE APPROACHES. CLOUDINESS MAY GET THICK WITH
BASES AS LOW AS 12 KFT MSL LATER TONIGHT...EXCEPT FOR SOME
REDEVELOPMENT OF STRATOCUMULUS DECKS OVER THE HIGHER TERRAIN EAST
AND NORTH OF PHOENIX AREA. EXPECT WINDS TO REMAIN LIGHT AND FAVOR
SOUTHWEST DIRECTIONS DURING THE DAY TRENDING TOWARD NORTHERLY
DIRECTIONS LATER TONIGHT.

SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA...INCLUDING KIPL AND
KBLH...
EXPECT NORTH WINDS TODAY BUT WITH MUCH LIGHTER SPEEDS THAN
YESTERDAY. NORTH WINDS CONTINUE TONIGHT AND STRENGTHEN...MORE
NOTICEABLY ALONG THE LOWER COLORADO RIVER VALLEY. EXPECT INCREASING
MAINLY HIGH CLOUDS TODAY WHICH MAY GET THICK ENOUGH FOR BASES OF
12-15 KFT MSL BEFORE CLEARING OVERNIGHT.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
TUESDAY THROUGH SATURDAY...
BREEZINESS FROM THE NORTH AND NORTHEAST WILL CONTINUE TUESDAY BUT
NOT BE AS STRONG OVER SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA
COMPARED TO MONDAY. LIGHTER NORTH AND NORTHEAST WINDS WILL CONTINUE
THE REST OF THE WEEK. HUMIDITIES WILL BE LOW TUESDAY BEFORE SLOWLY
REBOUNDING...MAINLY OVER SOUTH-CENTRAL ARIZONA. BELOW NORMAL
TEMPERATURES CAN BE EXPECTED TUESDAY FOLLOWED BY WARMING TO NEAR
NORMAL VALUES BY THURSDAY WITH LITTLE CHANGE THROUGH SATURDAY.
