AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
950 PM MST MON APR 3 2006

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

.SYNOPSIS...
A STRONG LOW PRESSURE SYSTEM OFF THE CALIFORNIA COAST WILL MOVE
SLOWLY EAST THROUGH ARIZONA OVER THE NEXT COUPLE OF DAYS. AS THIS
HAPPENS...WINDS WILL INCREASE...TEMPERATURES WILL COOL OFF AND THERE
WILL BE A CHANCE OF SHOWERS...FIRST OVER SOUTHEAST CALIFORNIA BY
TUESDAY...MOVING INTO SOUTH-CENTRAL ARIZONA BY EARLY WEDNESDAY.
WEATHER CONDITIONS WILL IMPROVE BY THURSDAY UNDER HIGHER PRESSURE
ALOFT...WITH A RETURN TO WARMER TEMPERATURES AND SUNNY SKIES THROUGH
NEXT WEEKEND.

&&

.SHORT TERM...
TONIGHT THROUGH THURSDAY...
SLOW MOVING PACIFIC UPPER TROF CONTINUES TO SPIN OFF THE NRN CA
COAST THIS EVENING...AND THE 00Z PLOT DATA INDICATED H5 HEIGHTS
ACTUALLY UP 10-20M OVER AZ...WITH THE COLDEST AIR STILL OVER FAR NRN
CA AND OFF THE W COAST. IR IMAGERY SHOWING THAT THE AMPLIFIED NATURE
OF THE TROF IS ALLOWING QUITE A BIT OF SUBTROPICAL MOISTURE TO BE
ENTRAINED BY THE TROF AND ADVECTED NEWD ACROSS OUR CWA...WITH THE
DEEPER MOISTURE OVER SERN CA...AND MAINLY THICK HI CLOUDS OVER THE
ARIZONA DESERTS. SAN DIEGO RAOB THIS EVE SHOWED ABOUT 1 INCH OF
PWAT...AND QUITE A BIT OF MOISTURE AT AND ABOVE 700MB...ALL OF THIS
STREAMING ACROSS THE COASTAL MOUNTAINS AND INTO OUR AREA. A WEAK
FAST MOVING RIPPLE IN THE SWLY FLOW MOVED THRU SERN CA EARLIER THIS
EVENING AND CAUSED SOME SPRINKLES/LIGHT SHOWERS OVER IMPERIAL AND
PARTS OF SERN CA...BUT IT WILL BE MOVING NEWD AND OUT OF THE AREA
AFTER MIDNIGHT...AND THE ASSOCIATED PRECIP WILL BE DIMINISHING.
STILL...THERE IS QUITE A BIT OF MOISTURE IN THE MID LEVELS OVER SERN
CA TONIGHT...SO THE FORECASTS WERE AMENDED TO ADD A SLIGHT CHANCE
FOR LIGHT SHOWERS TO SERN CA AND THE NRN CO RIVER OVERNIGHT...UNDER
MOSTLY CLOUDY SKIES. FORECASTS FOR THE ARIZONA PORTION OF THE CWA
TONIGHT ARE OK...WITH SKIES TO BE MOSTLY CLOUDY AND CLOUDS TO BE
GENLY ABOVE ABOUT 15000FT. WINDS WERE BREEZY FROM THE SOUTHWEST IN
THE LATE AFTERNOON AND EARLY EVENING OUT WEST...BUT HAVE DECREASED
SINCE 7 PM AND ARE NOW UNDER 15 MPH. EXPECT SOME INCREASE IN WINDS
LATER TONIGHT WEST OF THE CO RIVER AS GRADIENTS BEGIN TO TIGHTEN
AHEAD OF THE APPROACHING TROF. OTHERWISE...FORECASTS FOR TONIGHT ARE
FINE AND NO FURTHER UPDATES NEEDED. REST OF THE DISCUSSION IS FROM
THE PREVIOUS DAY SHIFT.

FIRST SHORTWAVE STILL EXPECTED TO ROTATE NEWD TUESDAY NIGHT...WHICH
WILL HELP TO ACCELERATE THE FRONTAL BAND EWD INTO OUR WRN CWA BY
THEN. NICE JET STREAK EXPECTED TO ROTATE AROUND THE BOTTOM OF THE
TROUGH BY TUE AFTERNOON/NIGHT...AND THIS WILL SERVE TO REALLY BEEF
UP THE WINDS OUT IN WRN CWA BY THEN. FOR NOW...WILL JUST GIVE SPEEDS
APPROACHING WIND ADVISORY LEVELS...IE GUSTS NEAR 40 MPH.
HOWEVER...LATER SHIFTS MAY NEED TO ISSUE A WIND ADVISORY FOR LATE
TUE/TUESDAY NIGHT AND INTO WED FOR WRN CWA. GUSTY WINDS ALSO
EXPECTED OVER ERN CWA BY WED BUT NOT LIKELY AS STRONG. WILL THROW IN
SOME BLOWING DUST WITH THE INCREASING WINDS. MOISTURE-WISE...SYSTEM
WILL BE LACKING IN DEEP-LAYERED RH...BUT SHOULD BE ENOUGH FOR
DYNAMICS TO INTERACT WITH TO CREATE SOME SHOWERS...SO WILL GO WITH
CHANCE TO SLIGHT CHANCE POPS. NOT EXPECTING MUCH OF ANY SIGNFICANCE
IN QPFS. TEMPS WILL BE A BIT LOWER TOMORROW...THEN MUCH COOLER ON
WEDNESDAY AS HEIGHTS DROP AND CLOUDS/SHOWERS ROAM THE AREA. TROUGH
SYSTEM WILL MOVE E OUT OF REGION BY LATE WED...AND BY THURSDAY
HIGHER PRESSURE ALOFT WILL RESULT IN SUNNIER WX...MUCH LESS WINDS
AND WARMER AFTERNOON TEMPS.

&&

.LONG TERM...
THURSDAY NIGHT THROUGH MONDAY...
PRETTY GOOD MODEL AGREEMENT ON RIDGING EARLY IN THE EXTENDED BUT IT
LOOKS TO BE SHORT LIVED AS YET ANOTHER TROUGH MOVES INTO THE WEST
COAST. THE 12Z GFS DEVELOPS DEEPER TROUGHING OVER CALIFORNIA SUNDAY
THAN DID THE 00Z RUN. THE 12Z RUN THEN MOVES A WEAKENING TROUGH INTO
ARIZONA MONDAY IN RESPONSE TO AN UPSTREAM SYSTEM. COOLER 12Z
SOLUTION IS SUPPORTED BY 00Z BASED GFS ENSEMBLE MEAN. ON THE OTHER
HAND...THE 12Z ECMWF WAS PRETTY SIMILAR TO THE 00Z GFS OPERATIONAL
RUN WHILE AN EXTRAPOLATION OF THE 12Z UKMET SUGGESTED AN EVEN WEAKER
SOLUTION. THUS...HELD OFF ON INTRODUCING SLIGHT CHANCE POPS IN THE
SUNDAY-MONDAY TIMEFRAME. HOWEVER...SHOWED MORE TEMPERATURE
FLUCTUATION WITH WARMING FRIDAY AND SATURDAY FOLLOWED BY NOTICABLE
COOLING SUNDAY AND MONDAY.
