AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
830 AM PDT SUN APR 3 2016

.SYNOPSIS...HIGH PRESSURE OVER THE PACIFIC NORTHWEST WILL SHIFT
EASTWARD THIS AFTERNOON. A COLD FRONT WILL SWEEP ACROSS THE AREA
TONIGHT. THE TRAILING TROUGH WILL USHER IN A COOLER AND UNSTABLE AIR
MASS WITH SHOWERS...ISOLATED THUNDERSTORMS...AND LOCALLY WINDY
CONDITIONS ON MONDAY. THE SNOW LEVEL WILL FALL TO THE HIGHER CASCADE
PASSES ON MONDAY. A STRONG RIDGE WILL DEVELOP WEDNESDAY AND THURSDAY
WITH TEMPERATURES WARMING WELL INTO THE 70S THURSDAY AND FRIDAY.

&&

.SHORT TERM...UPPER LEVEL RIDGING IS MOVING ACROSS WESTERN
WASHINGTON THIS MORNING WHILE HIGH PRESSURE OVER THE INTERIOR IS
SHIFTING EASTWARD. A COLD FRONT...NOW SITTING NEAR 131W...WILL MOVE
ONTO THE WASHINGTON COAST THIS EVENING THEN INLAND LATER TONIGHT.
WITH THE APPROACHING FRONT...LOW LEVEL PRESSURE GRADIENTS ARE
OFFSHORE. DESPITE THE AREAS OF MID AND HIGH LEVEL CLOUDS STREAMING
ACROSS THE INTERIOR THIS MORNING...IT APPEARS THAT TEMPERATURES THIS
AFTERNOON WILL TOP OUT IN THE MID TO UPPER 60S IN MANY PLACES...2-3
DEGREES HIGHER THAN THE CURRENT FORECAST. A QUICK SHORT TERM
FORECAST UPDATE WAS ISSUED THIS MORNING TO ACCOUNT FOR THE
ANTICIPATED WARMER CONDITIONS TODAY.

RAIN WILL LIKELY MOVE ONTO THE COAST AROUND 5 PM THEN WILL SPREAD
RAPIDLY EASTWARD INTO THE INTERIOR THIS EVENING. WITH SOUTHERLY
PRESSURE GRADIENTS ...NEARLY 4 MB KOLM-KBLI WITH THE FRONT... EXPECT
IT TO GET WINDY OVERNIGHT WITH THE FRONT AND AFTER IT PASSES IN THE
PUGET SOUND LOWLANDS. THE PRECIPITATION AND WIND FORECASTS ARE WELL
COVERED IN THE GOING FORECASTS.

THE AIR MASS WITH MONDAYS PASSING UPPER LEVEL TROUGH WILL BE COOL
AND UNSTABLE AS 500 MB TEMPERATURES WITH THE COLD POOL IN THE TROUGH
DROPPING TO AROUND -33C DURING THE AFTERNOON. THE HIRES ARW AND THE
12Z NAM12 BOTH SHOW INSTABILITY MARGINAL AT BEST FOR TSTMS WITH CAPE
VALUES ONLY 100J/KG AND LIFTED INDICES ONLY NEAR 0. BUT ONSHORE FLOW
WILL BE STRONG AND IT APPEARS THAT THERE WILL BE CONVERGENCE ZONE
ACTIVITY THAT WILL BEGIN OVER THE N PUGET SOUND AREA THEN SLIDE S
TOWARD THE SEATTLE METRO AREA DURING THE AFTERNOON HOURS. MODEL
OUTPUT STATISTICS CONTINUE TO SHOW A 15-30 PERCENT CHANCE OF TSTMS
ON MONDAY. WILL LEAVE THE ISOLATED TSTMS IN THE FORECAST FOR MONDAY
AT THIS TIME.

SNOW LEVELS FALL TO NEAR 3500 FEET MONDAY AFTERNOON AND EVENING WITH
STRONG ONSHORE FLOW AND CONVERGENCE ZONE ACTIVITY. SNOWFALL AMOUNTS
IN THE HIGHER PASSES AND PLACES LIKE MT BAKER AND PARADISE RANGER
STATION COULD GET HIGH ENOUGH TO JUSTIFY MARGINAL WINTER WEATHER
ADVISORIES LATE MONDAY MORNING THROUGH MONDAY EVENING. WILL TAKE A
LOOK AT THE COMPLETE 12Z MODEL SUITE BEFORE MAKING A DECISION AND
WILL ISSUE ANY ADVISORIES IF NEEDED WITH THE AFTERNOON FORECAST
PACKAGE.

ONSHORE FLOW AND SHOWER ACTIVITY DECREASE MONDAY NIGHT AS THE UPPER
TROUGH PULLS OFF TO THE EAST. THEN A WARM FRONT LIFTS NORTHEAST
ACROSS THE AREA TUESDAY AND TUESDAY NIGHT. LATEST MODEL GUIDANCE NOW
SHOWS RATHER LIGHT PRECIPITATION AMOUNTS WITH THIS WARM FRONT...
MAINLY ON THE OLYMPIC PENINSULA. ALBRECHT

.LONG TERM...FROM THE PREVIOUS LONG TERM DISCUSSION...MODELS HAVE
TRENDED STRONGER WITH THE RIDGE AMPLIFICATION OVER THE REGION
WEDNESDAY THROUGH THURSDAY. 500 MB HEIGHTS EXCEED 5800M BY THURSDAY
ON BOTH THE GFS AND ECMWF. WITH LIGHT OR OFFSHORE FLOW...HIGHS COULD
REACH THE MID/UPPER 70S OR EVEN NEAR 80 INLAND FROM THE WATER ON
THURSDAY. AVERAGE HIGHS ARE ONLY IN THE UPPER 50S THIS TIME OF YEAR
SO HIGH TEMPERATURES ON THURSDAY COULD BE +20F ABOVE NORMAL.

MODELS VARY ON THE RIDGE POSITION AND STRENGTH BY FRIDAY AND
SATURDAY. THE GFS SHOWS A MARINE PUSH DEVELOPING LATE FRIDAY
AFTERNOON BUT PROBABLY AFTER MANY AREAS REACH THE 70S ONCE AGAIN.
UPPER HEIGHTS ON THE ECMWF COME DOWN A LOW QUICKER WITH A STRONGER
TROUGH DIGGING SWD OUT OF B.C. FRIDAY INTO SATURDAY. THIS COULD
RESULT IN COOLER HIGHS THAN CURRENTLY FORECAST. WILL LEAVE
TEMPERATURES ALONE FOR NOW UNTIL THERE IS BETTER AGREEMENT. ONE
OTHER DIFFERENCE NOTED IS THE SLY MOISTURE FEED SHOWN BY THE GFS
FRIDAY WHICH COULD GENERATE SOME LIGHT RAIN. GIVEN THE OTHER DRY
MODEL SOLUTIONS THE GFS IS BEING DISCOUNTED FOR NOW. THE FORECAST
REMAINS DRY INTO SATURDAY WITH NO CLEAR SIGNAL FROM MODELS ON A
MAJOR PATTERN CHANGE.  MERCER

&&

.AVIATION...SOUTHWEST FLOW ALOFT OVER WESTERN WASHINGTON THIS
MORNING WITH UPPER LEVEL RIDGE AXIS NOW EAST OF THE CASCADES. WEAK
OFFSHORE LOW LEVEL FLOW WILL CONTINUE TODAY AS AN OFFSHORE FRONTAL
SYSTEM APPROACHES THE REGION. THE FRONTAL SYSTEM WILL MOVE THROUGH
THE FORECAST AREA TONIGHT THROUGH MONDAY MORNING WITH STRONGER
SOUTHERLY/ONSHORE FLOW...INCREASING MOISTURE...AND DETERIORATING
CONDITIONS.

BKN-OVC090 ACROSS THE FORECAST AREA THIS MORNING WITH LOCAL 4-6SM
BR...AND WE SHOULD SEE ONLY MID AND HIGH LEVEL CLOUDS INCREASING
THROUGH EARLY EVENING. CONDITIONS SHOULD DETERIORATE FAIRLY QUICKLY
LATER THIS EVENING WITH WIDESPREAD MVFR AND LOCAL IFR CONDITIONS
THROUGH MONDAY MORNING.

KSEA...SOUTHEAST WIND 3-6 KT...BECOMING SOUTHERLY 6-10 KT THIS
AFTERNOON AND RISING TO 14-22 KT GUSTING 30 KT LATE THIS EVENING.
RAIN SHOULD BEGIN AT KSEA AROUND 11 PM...WITH CONDITIONS
DETERIORATING TO OVC015-025. MCDONNAL

&&

.MARINE...LIGHT OFFSHORE SURFACE GRADIENTS WILL CONTINUE TODAY. A
COLD FRONT WILL MOVE ACROSS THE COASTAL WATERS LATE THIS EVENING AND
THE INLAND WATERS OF WESTERN WASHINGTON AFTER MIDNIGHT. THE FRONT
AND ESPECIALLY THE STRONG ONSHORE FLOW FOLLOWING IT SHOULD BRING
SOLID SMALL CRAFT ADVISORY SOUTHWEST TO WEST WINDS TO ALL
WATERS...WITH GALE FORCE WESTERLIES LIKELY IN THE CENTRAL STRAIT OF
JUAN DE FUCA AND EAST ENTRANCE STRAIT. THE GALE WATCH IS BEING
UPGRADED TO A GALE WARNING WITH THE MORNING FORECAST PACKAGE.

ONSHORE FLOW WILL WEAKEN MONDAY NIGHT AND TUESDAY WITH HIGH PRESSURE
BUILDING INLAND LATE IN THE DAY. THE HIGH WILL SHIFT EAST OF THE
CASCADES WEDNESDAY NIGHT AND THURSDAY WITH LOW LEVEL OFFSHORE FLOW
DEVELOPING. MCDONNAL
