AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
355 AM PDT SAT APR 2 2011

.SYNOPSIS...A COOL UPPER LEVEL TROUGH WILL MOVE OVER WESTERN
WASHINGTON TODAY KEEPING SHOWERS IN THE FORECAST. THE TROUGH WILL
SHIFT EAST TONIGHT INTO SUNDAY MORNING. ANOTHER WET WEATHER SYSTEM
WILL BE RIGHT ON THE TROUGHS HEELS WITH RAIN OUT AHEAD OF THE FRONT
SPREADING INTO THE COAST SUNDAY EVENING AND OVER THE REMAINDER OF
THE AREA LATER SUNDAY NIGHT. THE FRONT WILL MOVE THROUGH WESTERN
WASHINGTON MONDAY NIGHT. ANOTHER TROUGH WILL MOVE DOWN OVER THE AREA
FOR TUESDAY AND WEDNESDAY.

&&

.SHORT TERM...NOT TO BE OUTDONE BY MARCH...APRIL CAME IN LIKE A LION
ACROSS WESTERN WASHINGTON ON FRIDAY WITH RECORD RAINFALL IN THE
SEATTLE AREA. FRONT THAT BROUGHT THE RAIN TO THE AREA NOW OVER
EASTERN WASHINGTON. COOL UPPER LEVEL TROUGH MOVING INTO WESTERN
WASHINGTON THIS MORNING BEHIND THE FRONT KEEPING SHOWERS IN THE
FORECAST. IN ADDITION A PUGET SOUND CONVERGENCE ZONE HAS FORMED OVER
KING COUNTY WHICH WILL ENHANCE THE SHOWER ACTIVITY IN THE SEATTLE
AREA EARLY THIS MORNING. UPPER LEVEL TROUGH SLOWLY SHIFTING EAST
BEGINNING LATER THIS AFTERNOON THROUGH EARLY SUNDAY MORNING. AS THE
TROUGH MOVES THROUGH MORE CONVERGENCE POSSIBLE WITH ANOTHER WEST
WIND SURGE DOWN THE STRAIT. WITH THE FLOW ALOFT NORTHWESTERLY THIS
SHOULD PUSH THE CONVERGENCE A LITTLE FURTHER SOUTH THAN USUAL WITH
KING COUNTY ONCE AGAIN THE PRIME LOCATION LATE THIS AFTERNOON INTO
THE EARLY EVENING HOURS. FOR THE REMAINDER OF THE AREA A DECREASE IN
THE SHOWER ACTIVITY AS THE DAY WEARS ON WITH THE TROUGH MOVING IN.
AIR MASS SOMEWHAT UNSTABLE OVER WESTERN WASHINGTON TODAY WITH LIFTED
INDEXES NEAR 0 AND CONVECTIVE TEMPERATURES IN THE MID TO UPPER 40S
BUT WITH ALL OF THE LOW LEVEL MOISTURE AROUND NOT EXPECTING A LOT OF
SUNSHINE KEEPING THE CHANCES OF A THUNDERSTORM LOW. BEST CHANCES
WILL BE WITH THE CONVERGENCE ZONE BUT WITH THE PROBABILITY NOT VERY
HIGH WILL LEAVE THUNDER OUT OF THE ZONES FOR NOW. NEXT SYSTEM TO
MOVE INTO WESTERN WASHINGTON CURRENTLY BACK NEAR 160W MOVE EAST AT A
GOOD PACE. TPW IMAGERY SHOWS THIS SYSTEM ONCE AGAIN IS FAIRLY JUICY
FOR THE FIRST PART OF APRIL WITH SMALL POCKETS OF 1.5 TO 2 INCHES
EMBEDDED IN THE FRONT AND WIDESPREAD 1 TO 1.5 INCH VALUES WITH THE
SYSTEM. MODELS ARE CONSISTENT AND A LITTLE FASTER WITH THIS SYSTEM
THIS MORNING WITH THE RAIN POSSIBLY REACHING THE COAST AS EARLY AS
SUNDAY AFTERNOON WITH THE RAIN SPREADING INLAND SUNDAY EVENING. THE
COOL TROUGH BEHIND THE FRONT STARTS TO DIG SOUTH ON MONDAY AND THIS
WILL STALL THE FRONT OVER WESTERN WASHINGTON MAKING FOR ANOTHER VERY
WET DAY FOR THE REGION.

CLIMATE NOTE...SEATTLE TACOMA AIRPORT REPORTED 1.13 INCHES OF RAIN
YESTERDAY. THIS IS ONLY THE 11TH TIME IN THE HISTORY OF THE WEATHER
RECORDS AT SEA-TAC THAT THERE HAS BEEN A DAY IN APRIL WITH 1 INCH OR
MORE OF RAIN. NORMAL FOR THE ENTIRE MONTH OF APRIL IS ONLY 2.59
INCHES SO APPROXIMATELY 44 PERCENT OF THE NORMAL MONTHLY RAIN WAS
RECORDED ON FRIDAY.

.LONG TERM...THE EXTENDED MODELS ARE IN GOOD AGREEMENT THIS MORNING
IN THE SHORT TERM WITH THE FRONT MOVING OUT OF THE REGION MONDAY
NIGHT. UPPER LEVEL TROUGH REMAINING OFFSHORE THROUGH WEDNESDAY WITH
IMPULSES GETTING KICKED OUT OF THE TROUGH MOVING TROUGH WESTERN
WASHINGTON. ITS ENTIRELY POSSIBLE THAT BY THE MIDDLE OF NEXT WEEK
SOME LOCATIONS WILL SURPASS THEIR MONTHLY NORMAL RAINFALL TOTAL FOR
APRIL. UPPER LEVEL TROUGH BEGINS TO DIG SOUTH ON THURSDAY ON THE 00Z
MODELS AND RIGHT NOW THE MODELS ARE DRY ON FRIDAY. GIVEN THE WAY
THINGS HAVE PLAYED OUT OVER THE LAST FEW DAYS WILL STICK WITH THE
CLIMATOLOGY FORECAST FOR DAY 7 RIGHT NOW AND KEEP A CHANCE OF
SHOWERS IN THE FORECAST. FELTON

&&

.HYDROLOGY...RAIN ON FRIDAY AND FRIDAY NIGHT SLOWED DOWN THE
RECESSION OF THE RIVERS AND IN SOME CASES WITH THE RIVERS FLOWING
OUT OF THE CENTRAL CASCADES THERE WERE SOME SLIGHT RISES. NONE OF
THE RIVERS OUTSIDE OF THE SNOQUALMIE AT CARNATION WHERE A FLOOD
WARNING IS STILL IN EFFECT...ARE FORECASTED TO RISE BACK ABOVE FLOOD
STAGE THIS MORNING.

MODELS SHOW A WET PERIOD OVER THE NEXT FIVE DAYS. THE SYSTEM ON
MONDAY BEARS WATCHING WITH THE NEW MODELS RUNS SLOWING DOWN THE
EASTWARD PROGRESSION OF THE FRONT PLUS THE HIGH PRECIPITABLE WATER
VALUES EMBEDDED IN THE SYSTEM. ADD THIS IN WITH THE ALREADY
SATURATED SOILS AND THERE IS THE POTENTIAL THAT A FLOOD WATCH COULD
BE ISSUED LATER TODAY OR SUNDAY. RIGHT NOW FORECASTED QPF VALUES FOR
MONDAY INTO MONDAY NIGHT ARE NOT ENOUGH TO PUSH RIVERS IN WESTERN
WASHINGTON BACK UP TO FLOOD STAGE BUT THE MODEL TRENDS HAVE BEEN
GETTING WETTER AND SLOWER WITH THIS SYSTEM. ONCE THIS SYSTEM MOVES
THROUGH MONDAY NIGHT FLOODING IS UNLIKELY ON ANY RIVER...INCLUDING
THE GREEN FOR THE REMAINDER OF THE WEEK. FELTON

&&

.AVIATION...UPPER TROF OVR WA MOVING INLAND TODAY. NW FLOW ALF. LOW
LEVEL ONSHORE FLOW WILL PERSIST. CIGS AND VSBY MAY STAY LOW IN THE
PSCZ AREA THRU THE MORNING...AS WELL AS NEAR THE FOOTHILLS AND MTNS
THRU IN THE MOIST ONSHORE FLOW. AIR MASS BECOMING UNSTABLE TODAY.

KSEA...LOW CIGS AND SHOWERS IN THE PSCZ AROUND SEATTLE EARLY THIS
MORNING. AS GRADIENTS BECOME MORE SLY OVER PUGET SOUND THE PSCZ
SHOULD SHIFT NORTH TO KPAE...POSSIBLY AS EARLY AS DAYBREAK WITH
IMPROVEMENT FOR THE SEATTLE AREA.

&&

.MARINE...ONSHORE FLOW WILL CONTINUE WITH LOW PRES INLAND AND HIGHER
PRES OFFSHORE. THE GRADIENT OVER PUGET SOUND HAS REVERSED FROM NLY
EARLIER TO MORE SWLY...WHICH WILL PUSH THE PSCZ NORTH AS THE SW FLOW
INCREASES INTO THE SOUTH SOUND. ONSHORE FLOW RELAXES LATE
TODAY...BECOMING LIGHT ON SUNDAY.
