AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
227 PM MST FRI FEB 25 2011

.SYNOPSIS...
THE NEXT STORM SYSTEM TO IMPACT THE REGION IS EXPECTED TO SPREAD
SHOWERS FROM SOUTHEAST CALIFORNIA...EAST ACROSS SOUTHWEST ARIZONA
SATURDAY AND SATURDAY EVENING...THEN INTO SOUTH CENTRAL
ARIZONA...INCLUDING THE GREATER PHOENIX AREA...SATURDAY NIGHT AND
EARLY SUNDAY. THE SNOW LEVEL IS EXPECTED TO DROP TO BETWEEN 2 AND 3
THOUSAND FEET. IT WILL BE WINDY SATURDAY INTO SATURDAY NIGHT...AND
MUCH COLDER THIS WEEKEND. AFTER COLD WEATHER SUNDAY NIGHT...DRY AND
SIGNIFICANTLY WARMER WEATHER IS FORECAST NEXT WEEK...AS HIGH
PRESSURE ALOFT FROM THE PACIFIC MOVES OVER THE AREA.

&&

.DISCUSSION...
MID AND HIGH LEVEL CLOUDS ARE MOVING INTO CENTRAL AND NORTHERN
ARIZONA TODAY...AHEAD OF A STRONG AND WET PACIFIC LOW PRESSURE
SYSTEM CURRENTLY SPINNING OFF THE NORTHERN CA COAST. AS THE LOW
CONTINUES TO MOVE SOUTHWARD...A DECENT FETCH OF LOW/MID LEVEL
MOISTURE WILL CONTINUE TO STREAM INTO CA. THE COLD LOW /517
DAM/...COMBINED WITH PLENTY OF MOISTURE /1000-700MB MIXING RATIO OF
5 G/KG AND PWATER ON THE ORDER OF 0.50 AND 0.70 INCHES/...WILL LEAD
TO PRECIPITATION OVER CENTRAL AND SOUTHERN CA TODAY AND TONIGHT...
SPREADING INTO OUR SOUTHEAST CA DESERTS BY SAT MORNING. WE WILL ALSO
SEE INCREASING WINDS AS THE LOW APPROACHES...AND HAVE ALREADY ISSUED
A WIND ADVISORY FOR PORTIONS OF THE SOUTHEAST CA DESERTS OVERNIGHT
TONIGHT. HOWEVER...THE STRONGEST WINDS ARE EXPECTED IN CONJUNCTION
WITH THE LOW LEVEL JET MOVING THROUGH S-CENTRAL AZ LATE SATURDAY
AFTERNOON AND EARLY EVENING AND A WIND ADVISORY IS ALSO IN EFFECT
FOR SOUTHERN MARICOPA...NORTHERN PINAL...AND SOUTHERN GILA COUNTIES
FOR THIS TIME PERIOD. WE CAN ALSO EXPECT AREAS OF BLOWING DUST OVER
SOUTHERN PORTIONS OF OUR CWA...MAINLY SOUTHERN MARICOPA AND NORTHERN
PINAL COUNTIES...WITH VISIBILITY POSSIBLY FALLING BELOW 2 MILES
POSSIBLE AT TIMES.

THE MAIN PRECIP THREAT FOR THE CENTRAL DESERTS STILL LOOKS LIKE
OVERNIGHT SAT INTO SUN...WITH QPF ON THE ORDER OF 0.30 TO 0.60
INCHES. BY SUN MORNING...SNOW LEVELS SHOULD DROP TO AROUND
2000-2500 FEET AS THE 527 DAM LOW MOVES THROUGH...WITH 4 TO 6 INCHES
ACCUMULATION POSSIBLE ABOVE 5000 FEET. HAVE ISSUED A WINTER STORM
WATCH FOR THIS AREA...IN EFFECT 06Z TO 00Z /OVERNIGHT SAT INTO SUN/.
FORECAST SOUNDINGS FOR THE REGION ALSO INDICATE LI/S GO NEG AROUND
EARLY SUN MORNING...SO CANNOT RULE OUT AN EMBEDDED WEAK
THUNDERSTORMS AS THE HEAVIEST SHOWERS MOVE THROUGH S-CENTRAL AZ
OVERNIGHT SAT/EARLY SUNDAY.

BY MID DAY SUNDAY...THE LOW WILL START TO FILL AND LIFT
NORTHEASTWARD. HOWEVER...BOTH 12Z ECMWF AND GFS RUNS THIS MORNING
INDICATE THE LOW WILL BE SLOWER TO DEPART THE STATE THAN PREVIOUS
RUNS INDICATED...AND HAVE INCREASED THE 12 HOUR POPS FOR SUN FROM
THE CENTRAL AZ DESERTS EASTWARD...WHILE INDICATING THE BEST CHANCES
FOR PRECIP WILL BE DURING THE FIRST HALF OF THE DAY. TEMPERATURES
SUNDAY WILL TOP OUT IN THE LOW TO MID 50S FOR HIGHS ACROSS THE AZ
DESERTS...NEAR 60 OVER OUR WESTERN CWA. THIS IS CLOSE TO 15-20 DEG
BELOW NORMAL FOR LATE FEBRUARY. THE LOW HIGH RECORD FOR KPHX FOR
SUNDAY FEB 27 IS 54 SET IN 1962...AND THIS IS ALSO OUR CURRENT
FORECAST HIGH FOR THE DAY. AS THE SHOWERS FINALLY MOVE EASTWARD
SUNDAY EVENING...THIS WILL ALLOW FOR MAXIMUM OVERNIGHT COOLING...AND
LOW TEMPS ACROSS THE DESERTS WILL BOTTOM OUT IN THE UPPER 20S TO
MID/UPPER 30S EARLY MON MORNING.

FOR MONDAY INTO THE MIDDLE OF THE WEEK...WE SHOULD SEE DRY
CONDITIONS ALONG WITH A WARMING TREND AS HIGH PRESSURE BUILDS INTO
THE DESERT SOUTHWEST. THERE WILL BE OCCASIONAL HIGH CLOUDS AS WEAK
DISTURBANCES MOVE THRU THE FLOW...BUT NO PRECIP IS EXPECTED. HIGH
TEMPS SHOULD CLIMB INTO THE 70S BY TUESDAY...THEN INTO THE UPPER 70S
TO NEAR 80 BY THURSDAY.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX AND KIWA...AND
SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA INCLUDING KIPL AND KBLH...

MOSTLY CLEAR SKIES AND LIGHT WINDS ARE EXPECTED THROUGH EARLY FRIDAY
AFTERNOON. WINDS AND HIGH CLOUDINESS WILL THEN BEGIN INCREASING IN
SOUTHEAST CA THROUGH FRIDAY EVENING...IN ADVANCE OF AN APPROACHING
STORM SYSTEM. KIPL AND NEARBY AREAS JUST DOWNWIND FROM THE COASTAL
MOUNTAINS WILL SEE WIND GUSTS NEAR 24 KTS BY 02Z FRIDAY EVENING.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
SUNDAY THROUGH THURSDAY...
A COLD AND WET PACIFIC STORM SYSTEM WILL BRING UNSEASONABLY COLD
TEMPERATURES...SHOWERS...HIGHER ELEVATION SNOW SHOWERS...AND BREEZY
TO WINDY CONDITIONS TO THE REGION ON SUNDAY. UPPER LEVEL HIGH
PRESSURE WILL THEN BEGIN BUILDING BACK INTO THE SOUTHWEST ON
MONDAY...BRINGING A RETURN OF WARMER AND DRIER WEATHER. BY THE
MIDDLE OF THE WEEK...HIGH TEMPERATURES IN THE LOWER DESERT WILL RISE
INTO THE LOW TO MID 70S...WHICH IS SLIGHTLY ABOVE NORMAL. MINIMUM
RELATIVE HUMIDITY VALUES WILL FALL INTO THE TEENS ACROSS MUCH OF THE
