AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
330 PM PDT THU MAR 19 2009

.SYNOPSIS...SHOWERS WILL PERSIST ACROSS THE AREA TONIGHT WITH SNOW
IN THE MOUNTAINS. A FRONT WILL BRING MORE RAIN TO THE AREA FRIDAY.
AN UPPER LEVEL TROUGH OFFSHORE WILL MOVE SLOWLY INLAND THIS
WEEKEND...MAINTAINING A CHANCE OF SHOWERS OVER THE AREA. A WARM
FRONT WILL BRING RAIN TO THE AREA MONDAY WITH A SERIES OF SYSTEMS
MAINTAINING UNSETTLED WEATHER THROUGH MID WEEK.

&&

.SHORT TERM...SHOWERS HAVE DECREASED IN COVERAGE AS THE BULK OF DEEP
MOISTURE SHIFTS EWD. SATELLITE IMAGERY STILL SHOWS A LOT OF LOW
CLOUD OFF THE COAST WITH MODELS KEEPING SOME LIGHT QPF AROUND
TONIGHT SO EXPECT SHOWERS TO CONTINUE. THE NORTH CASCADES ARE THE
ONE SPOT PICKING UP SOME HIGHER QPF AMOUNTS TODAY WITH THE MODELS
SHOWING TOTALS UP TO AN INCH LIQUID AROUND MT BAKER BY LATER THIS
EVENING. PUT OUT A WINTER WEATHER ADVISORY THROUGH MIDNIGHT FOR THE
NORTH CASCADES TO COVER THIS AREA OF HIGHER SNOWFALL. SNOW LEVELS
ARE RUNNING AROUND 4500 FEET SOUTH AND 4000 FEET NORTH WITH ONLY A
COUPLE INCHES IN THE PASSES WHICH ARE NOT FAVORED BY THIS SLY FLOW
REGIME.

MODELS BRING MORE RAIN TO THE COAST FRIDAY MORNING AS THE NEXT FRONT
APPROACHES. RAIN WILL SPREAD INLAND DURING THE DAY WITH COLDER AIR
FILTERING IN DURING THE AFTERNOON. AGAIN...MOUNTAIN SLOPES FAVORED
BY S/SW FLOW WILL INITIALLY DO THE BEST PROBABLY WARRANTING A WINTER
WEATHER ADVISORY. WILL LET THE NEXT SHIFT DECIDE ON
EXPANDING/EXTENDING THE WINTER WEATHER ADVISORY FOR FRIDAY. THE GFS
CONTINUES TO BACK OFF ON THE POST FRONTAL FLOW INTO THE MOUNTAINS SO
THE PASSES MAY NOT RECEIVE ADVISORY AMOUNTS FROM THIS SYSTEM. SNOW
LEVELS FALL OFF TO AROUND 2000-3000 FEET BY FRIDAY EVENING BUT IT NO
LONGER LOOKS COLD ENOUGH FOR ANY MIXED PRECIP ACROSS THE LOWLANDS.

RAIN BECOMES SHOWERS FRIDAY NIGHT WITH THE GFS CONFINING MOST THE
QPF TO THE COAST/MOUNTAINS. HOWEVER...WITH MOIST SWLY FLOW IT WOULD
SEEM THERE IS SOME LOW THREAT OF RAIN JUST ABOUT ANYWHERE SO I WILL
LEAVE THE CHANCE POPS IN FOR THE LOWLANDS TOO.

THE NEXT TROUGH APPROACHING THE AREA SPLITS ON SATURDAY WITH THE
BULK OF ENERGY AND MOISTURE HEADING TO CA. MODELS HAVE MOSTLY BEEN
CONSISTENT WITH THIS IDEA. THE QUESTION REMAINS OF HOW MUCH NORTHERN
STREAM ENERGY MAKES IT ACROSS WA. THE GFS STILL KEEPS SPATS OF QPF
OVER PARTS OF WRN WA SATURDAY NIGHT AND SUNDAY. WITH RIDGING JUST
OFFSHORE SUNDAY AFTERNOON...IT IS POSSIBLE WE COULD START TO SEE
SOME SUN BREAKS WITH PRECIP ENDING ACROSS THE AREA. UNFORTUNATELY
THE ECMWF CONTINUES TO MAKE FORECAST LIFE DIFFICULT AS IT HAS
GENERALLY UNDERPERFORMED AGAINST THE GFS THE PAST WEEK OR MORE. BUT
THE CLOSED UPPER LOW AND GENEROUS QPF SHOWN ON SUNDAY ALSO CANT BE
COMPLETELY DISCOUNTED. WILL LEAVE CHANCE POPS IN THROUGH THE DAY.

.LONG TERM...MODELS ARE HINTING AT A POSSIBLE DRY PERIOD SUNDAY
NIGHT BUT MODELS DO NOT ALL AGREE ON THIS SCENARIO. EVEN WITH
SOME UPPER RIDGING THE ECMWF KEEPS SOME VERY LIGHT QPF AROUND. WILL
WAIT FOR A COUPLE MORE MODEL RUNS BEFORE GOING OUT ON A LIMB AND
FORECASTING A DRY PERIOD. LONG RANGE MODELS DO BRING A WARM FRONT
INTO THE AREA ON MONDAY SO ANOTHER ROUND OF RAIN IS LOOKING MORE
PROBABLE. THEREAFTER...BOTH THE GFS/ECMWF BRING A SERIES OF SYSTEMS
ACROSS THE AREA THROUGH AT LEAST MID WEEK. SOME MODEL RUNS HAVE
HINTED AT DRIER CONDITIONS BY WEDNESDAY OR THURSDAY BUT THIS REMAINS
TO BE SEEN. WILL STICK TO CLIMO CHANCE OF RAIN FOR NOW.  MERCER

&&

.AVIATION...CEILINGS GENERALLY IN THE 1-3K FT RANGE WITH ONLY SLIGHT
IMPROVEMENT EXPECTED AFTER SUNSET. LIGHT RAIN WILL CHANGE TO
SCATTERED SHOWERS BUT CEILINGS WILL REMAIN MVFR WITH OCCASIONAL
FORAYS INTO IFR OVERNIGHT. NEXT FRONT IS DUE FRIDAY MORNING WITH
MORE RAIN AND SOME WIND.

KSEA...THE PREVAILING CONDITIONS SHOULD BE CEILINGS AROUND 2K FT...
CURRENT IFR CEILINGS NOTWITHSTANDING. WINDS WILL BE SOUTHERLY 5-8 KT
THROUGH THE NIGHT...THEN START TO INCREASE TO 8-12 KT AFTER 12Z.
AFTER 20Z OR SO THERE WILL BE A PUSH OF SOUTHWEST WINDS FOR SEVERAL
HOURS...12-22 KT SOUNDS ABOUT RIGHT. CHB

&&

.MARINE...CURRENT DISINTEGRATING FRONT HAD ENOUGH PUNCH TO BRING LOW
END SMALL CRAFT ADVISORY WINDS TO MOST WATERS. THE INLAND WATERS
ADVISORIES WILL COME DOWN EARLY THIS EVENING BUT THE ONES ON THE
COAST WILL CONTINUE AS THE NEXT SYSTEM IS BEARING DOWN. THIS NEXT
SYSTEM LOOKS A BIT STRONGER AND HAVE INDICATED SMALL CRAFT ADVISORY
WINDS MOST WATERS FRIDAY. THIS INCLUDES A WESTERLY PUSH IN THE
AFTERNOON IN THE STRAIT AND SOUTHWEST WINDS IN PUGET SOUND AND HOOD
CANAL.

GFS MODEL INDICATES A LULL SATURDAY WITH LIGHT OFFSHORE FLOW BETWEEN
SYSTEMS. THEN A SERIES OF WEAK SYSTEMS MOVES IN...ABOUT ONE PER DAY
SUNDAY THROUGH TUESDAY. CHB
