AREA FORECAST DISCUSSION...UPDATED AVIATION DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
620 AM MST MON JAN 28 2008

SOUTH-CENTRAL AND SOUTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA
FORECAST DISCUSSION

.SYNOPSIS...
A STRONG LOW PRESSURE AREA MOVING EAST ACROSS THE WESTERN UNITED
STATES WILL CONTINUE A CHANCE OF SHOWERS OVER SOUTH-CENTRAL ARIZONA
TODAY WITH THE SNOW LEVEL ABOVE 55 HUNDRED OR 6 THOUSAND FEET.
WEAK HIGH PRESSURE ALOFT WILL BRING DRIER WEATHER BY TUESDAY.
ANOTHER LOW PRESSURE SYSTEM FROM THE GULF OF ALASKA WILL BRING A
SLIGHT CHANCE OF SHOWERS WEDNESDAY AND WEDNESDAY NIGHT FOLLOWED BY
DRY WEATHER THURSDAY INTO THE WEEKEND. YET ANOTHER PACIFIC LOW NORTH
PACIFIC LOW PRESSURE SYSTEM MAY BRING AN ADDITIONAL CHANCE OF
SHOWERS BY SUNDAY. COOLER THAN AVERAGE TEMPERATURES FOR LATE JANUARY
AND EARLY FEBRUARY ARE EXPECTED THIS WEEK.

&&

.SHORT TERM...
TODAY THROUGH WEDNESDAY...
IT HAS BEEN A BUSY OVERNIGHT DEALING WITH FLASH FLOOD WARNINGS AND
AN URBAN AND SMALL STREAM FLOOD ADVISORY. THE SHOWERS OVER
SOUTH-CENTRAL ARIZONA HAVE BEEN DECREASING VERY EARLY THIS
MORNING...BUT AS OF 4 AM MST...THERE WERE STILL SOME BANDS OF
SHOWERS FROM SOUTHWEST TO NORTHEAST MOVING ACROSS THE AREA...THE
MOST SIGNIFICANT OF WHICH EXTENDED ACROSS THE GREATER PHOENIX AREA
NORTHEAST ACROSS NORTHEAST MARICOPA COUNTY TO WESTERN GILA COUNTY.
GAGES WERE STILL INDICATING NEAR FLOOD STAGE ON AGUA FRIA RIVER AT
ROCK SPRINGS AND ON THE CAVE CREEK AT SPUR CROSS BUT SLOWLY
BEGINNING TO COME DOWN.

RECEIVED AN ISOLATED REPORT OF FOG WITH VISIBILITY DOWN TO NEAR ONE
QUARTER OF A MILE AT THE YUMA PROVING GROUND NORTHEAST OF YUMA THIS
MORNING. WITH THE AIRMASS AS SATURATED AS IT IS...WILL HAVE TO WATCH
FOR PATCHY FOG DEVELOPING THIS MORNING...BUT EXPECT IT WILL BE OF
MINIMAL COVERAGE.

THE LOW PRESSURE IMPULSE RESPONSIBLE FOR THE SHOWERS OVER
SOUTH-CENTRAL ARIZONA WILL MOVE EAST WITH DECREASING SHOWERS
EXPECTED THIS MORNING. HOWEVER...ANOTHER LOW PRESSURE SYSTEM WILL
BRING SOME INCREASE IN SHOWERS TO SOUTH-CENTRAL ARIZONA MAINLY NORTH
AND EAST OF PHOENIX THIS AFTERNOON INTO THIS EVENING...BUT NOT
NEARLY AS MUCH RAIN IS EXPECTED AS OCCURRED YESTERDAY AFTERNOON AND
EVENING.

AS THIS LOW PRESSURE SYSTEM APPROACHES AND MOVES THROUGH THE AREA...
GUSTY WINDS ARE EXPECTED TO INCREASE TODAY WITH STRONG GUSTY WINDS
IN SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA AND BREEZY ELSEWHERE
TODAY. PLAN ON ISSUING A WIND ADVISORY SHORTLY FOR PORTIONS OF
SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA FOR LATE THIS MORNING AND
THIS AFTERNOON INTO THIS EVENING.

THE LOW PRESSURE SYSTEM WILL MOVE EAST OF OUR AREA WITH THE CHANCE
OF SHOWERS IN SOUTH-CENTRAL ARIZONA ENDING BY LATE TONIGHT FOLLOWED
BY MOSTLY SUNNY SKIES BUT COOL WEATHER ACROSS THE ENTIRE AREA
TUESDAY.

ANOTHER LOW PRESSURE SYSTEM FROM THE GULF OF ALASKA WILL BRUSH
SOUTH-CENTRAL ARIZONA WITH A SLIGHT CHANCE OF SHOWERS THERE
WEDNESDAY WITH THE SNOW LEVEL NEAR 4 THOUSAND FEET.

&&

.LONG TERM...
WEDNESDAY NIGHT THROUGH SUNDAY...
LOW PRESSURE TROF IS FORECAST TO DIVE SOUTHEAST AND ACROSS MAINLY
SOUTH-CENTRAL ARIZONA WEDNESDAY NIGHT...AND IT WILL BRING AT LEAST A
SLIGHT CHANCE FOR SHOWERS TO THE AREA FROM PHOENIX EASTWARD. IT
SHOULD MOVE THRU QUICKLY...WITH DRIER NORTHWEST FLOW AND HIGHER
HEIGHTS SET TO FOLLOW THURSDAY. LONG WAVE PATTERN HAS A GENERAL
...BROAD TROFFING OVER THE WESTERN UNITED STATES...AND THIS LEAVES
OUR AREA SUSCEPTIBLE TO PASSING AND DEEPENING SHORT WAVES MOVING
THRU THE LONG WAVE TROF. DRY WEATHER IS FORECAST THURSDAY THROUGH
SATURDAY...BUT THIS IS NOT A WARM PATTERN SO MAX TEMPS WILL NOT
CHANGE MUCH AND SHOULD STAY BELOW SEASONAL NORMALS. ANOTHER
POTENTIALLY COLDER TROF IS FORECAST TO MOVE INTO ARIZONA ON SUPER
BOWL SUNDAY. MEX POPS ATTM ARE RATHER LOW...UNDER 30 PERCENT...BUT
BOTH EUROPEAN AND GFS ARE FORECASTING A WEEKEND TROF...AND RECENT
SPAGHETTI ENSEMBLES SHOW REMARKABLE CONSISTENCY AMONG THE VARIOUS
MEMBERS ACROSS THE ERN PACIFIC AND WESTERN UNITED STATES. THIS
SUGGESTS THAT WE MAY WELL HAVE ANOTHER WEATHER MAKER ON OUR HANDS
FOR THE UPCOMING WEEKEND. HAVE ADDED SLIGHT CHANCE POPS TO THE
FORECAST FOR SUNDAY...AND DROPPED HIGH TEMPS A FEW DEGREES FROM
SATURDAY.

&&

.AVIATION...
JANUARY 28 1300 UTC (JANUARY 28 0600 MST)

FOR KPHX/KIWA AND VALLEY AIRFIELDS...SCATTERED LIGHT RAIN WITH
CEILINGS AROUND 3500 FEET AGL THROUGH 15Z. AFTER 15Z AND
CONTINUING THROUGH 23Z...THE CHANCE FOR RAIN WILL RAPIDLY
DIMINISH...WITH CEILINGS LIFTING TO BETWEEN 5000 AND 6000 FEET AGL.
