AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
930 AM PDT SUN APR 29 2012

.SYNOPSIS...A WEAK UPPER RIDGE WILL MOVE EAST OF THE CASCADES TODAY
AND FLATTEN. CLOUDY SKIES AND AREAS OF MORNING DRIZZLE SHOULD GIVE
WAY TO PARTLY SUNNY SKIES THIS AFTERNOON. A PACIFIC FRONTAL SYSTEM
WILL SPREAD RAIN ACROSS WESTERN WASHINGTON TONIGHT AND MONDAY...AND
AN UPPER TROUGH WILL BRING COOL SHOWERY WEATHER LATE MONDAY THROUGH
WEDNESDAY. ANOTHER FRONTAL SYSTEM WILL BRING MORE RAIN THURSDAY AND
SHOWERS ON FRIDAY.

&&

.SHORT TERM...A WEAK UPPER RIDGE OVER THE PAC NW WILL MOVE EAST AND
FLATTEN OUT TODAY. BY THIS AFTN...THIS WILL ESSENTIALLY LEAD TO
ZONAL WESTERLY FLOW ALOFT. PRESSURE GRADIENTS ARE PRETTY FLAT THIS
MORNING OVER WRN WA...THOUGH THE 12Z KUIL SOUNDING SHOWED A MOIST
AIR MASS EXTENDING UP OVER 7000 FT MSL. ABUNDANT THICK LOW CLOUDS
COVER THE LOWLANDS THIS MORNING WITH SPOTTY AREAS OF DRIZZLE.
INDICATIONS REMAIN THAT THE LOW CLOUDS WILL SCATTER A BIT THIS
AFTN...ALLOWING A FEW PEEPS OF SUNSHINE TO OCCASIONALLY BEAM THROUGH
A GRAY SKY. BY LATE AFTN THOUGH...HIGH CLOUDS WILL THICKEN QUICKLY
AND BECOME MORE OPAQUE...SO LOOKING AT ONLY A NARROW WINDOW OF TIME
THROUGH WHICH THE SUN MAY PEAK. DRIZZLE SHOULD NO LONGER BE A
LOWLAND CONCERN THIS AFTN...BUT DEEP MOISTURE AND A LITTLE ONSHORE
FLOW THIS AFTN WILL CAUSE LIGHT SHOWERS TO DEVELOP OVER THE MTNS.
THE CURRENT FORECAST IS IN GOOD SHAPE WITH NO FORECAST UPDATES
EXPECTED THIS MORNING.      HANER

REST OF SHORT TERM DISCUSSION FROM PREVIOUS...
A FRONTAL SYSTEM IN THE WESTERLIES...CURRENTLY CROSSING 140W...WILL
MOVE INTO THE PACIFIC NORTHWEST TONIGHT. PRECIPITATION SHOULD SPREAD
ACROSS THE ENTIRE FORECAST AREA TO THE CASCADE CREST BY LATE
TONIGHT. THE FRONT WILL MOVE THROUGH THE AREA MIDDAY MONDAY.
PRECIPITATION WILL BECOME SHOWERY MONDAY AFTERNOON AND CONTINUE
THROUGH MONDAY NIGHT AS THE UPPER TROUGH FOLLOWS THE FRONT INTO THE
AREA. BREEZY CONDITIONS WILL DEVELOP LATE MONDAY OR MONDAY NIGHT AS
SURFACE HIGH PRESSURE BUILDS FROM THE SOUTHWEST...AND A PUGET SOUND
CONVERGENCE ZONE WILL DEVELOP. WESTERLY FLOW FOLLOWING THE FRONT
WILL MAINTAIN DECENT PRECIPITATION RATES ALONG THE WEST SLOPES OF
THE CASCADES.

A SECOND UPPER TROUGH WILL MOVE QUICKLY OVER THE REGION ON TUESDAY
AND THEN MOVE EAST OF THE CASCADES TUESDAY NIGHT. ONSHORE FLOW WILL
CONTINUE AS THE AIR MASS COOLS FURTHER. THE SHOWERY WEATHER WILL
CONTINUE AND THE CONVERGENCE ZONE -- WHICH WILL PROBABLY FIRST
DEVELOP LATE MONDAY -- SHOULD KEEP GOING ALL THE WAY THROUGH TUESDAY
NIGHT.

THE FRONTAL SYSTEM ARRIVING TONIGHT IS CARRYING LOTS OF MOISTURE...
AND THE MODELS HAVE BEEN TRENDING UPWARD WITH PRECIPITATION AMOUNTS.
STORM TOTAL PRECIPITATION TONIGHT THROUGH MONDAY NIGHT WILL RANGE
FROM 1.5 TO 3.5 INCHES IN THE CASCADES...1 TO 2.5 INCHES IN THE
OLYMPICS...AND UP TO 1 INCH OVER THE LOWLANDS. THE SNOW LEVEL WILL
START AROUND 6000 FT...FALL TO AROUND 4000 FT BEHIND THE COLD FRONT
MONDAY NIGHT AND THEN TO AROUND 3000 FT ON TUESDAY.

OBVIOUSLY THIS WILL DRIVE RISES ON RIVERS ESPECIALLY FROM THE
SNOQUALMIE RIVER NORTHWARD...BUT GUIDANCE FROM THE NORTHWEST RIVER
FORECAST CENTER DOES NOT SHOW ANY RIVER GETTING VERY CLOSE TO FLOOD
STAGE. AND IT SHOULD BE NOTED THAT RIVER FLOODING IN WESTERN
WASHINGTON AFTER MARCH IS QUITE RARE. ANOTHER THING WE WILL NEED TO
CONSIDER FOR THE CASCADES MONDAY NIGHT AND TUESDAY IS A WINTER
WEATHER ADVISORY.   MCDONNAL

.LONG TERM...FROM PREVIOUS DISCUSSION...WEAK UPPER RIDGE WILL MOVE
OVER WESTERN WASHINGTON WEDNESDAY FOR A RELATIVE BREAK IN THE
WEATHER. THEN ANOTHER FRONTAL SYSTEM WILL SPREAD ANOTHER ROUND OF
PRECIPITATION ACROSS THE FORECAST AREA WEDNESDAY NIGHT OR THURSDAY.
THE UPPER TROUGH WILL FOLLOW THE FRONT WITH A SHOWERY REGIME
THURSDAY NIGHT AND FRIDAY. THE TROUGH WILL MOVE EAST AND AN UPPER
RIDGE WILL PROBABLY BUILD OVER THE PACIFIC NORTHWEST ON SATURDAY.
MCDONNAL
