AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
910 AM PST THU JAN 14 2010

.SYNOPSIS...AN UPPER HIGH OVER THE REGION WILL SLOWLY MOVE EAST
THROUGH TONIGHT...ALLOWING A LOW PRESSURE SYSTEM THAT HAS TAPPED
INTO SUBTROPICAL MOISTURE TO HEAD TOWARD THE AREA.  THIS COMBINED
WITH THE DEVELOPMENT OF STRONG UPSLOPE FLOW AND RISING SNOW LEVELS
WILL RESULT IN HEAVY RAIN AT TIMES ON THE SOUTH OR SOUTHWEST FACING
SLOPES OF THE OLYMPICS AND NORTH CASCADES...ESPECIALLY TONIGHT
THROUGH FRIDAY.  THE FRONT WILL STALL AND WEAKEN OVER THE SOUTHWEST
PART OF THE STATE FRIDAY NIGHT BEFORE SHIFTING NORTH DURING THE DAY
SATURDAY.

&&

.SHORT TERM...AREAS OF RAIN ARE SPREADING INLAND THIS MORNING AND
ARE THE ADVANCE GUARD OF THE NEXT FRONTAL SYSTEM THAT WILL AFFECT
THE AREA INTO THE WEEKEND.  THIS WARM FRONT WILL MOVE NE ACROSS WRN
WA TODAY WITH THE COLD FRONT HOLDING BACK JUST OFFSHORE AND UP
ACROSS THE SOUTHERN PART OF VANCOUVER ISLAND.  A WEAK LOW PRESSURE
CENTER IS EXPECTED TO MOVE UP THE FRONT TONIGHT WHICH WILL THEN
FORCE THE COLD FRONT ACROSS THE AREA DURING THE DAY FRIDAY.  THIS
SCENARIO IS GOOD FOR STEADY...OCCASIONALLY HEAVY RAINS ACROSS THE
OLYMPIC PENINSULA THROUGH MOST OF FRIDAY.  THE REST OF THE AREA WILL
SEE OCCASIONAL LIGHTER RAINS...WITH LESS THE FURTHER SOUTHEAST YOU
GO.  THIS WILL ALSO MAINTAIN SOMEWHAT BREEZY CONDITIONS ACROSS THE
NW HALF OF THE FORECAST AREA THROUGH TONIGHT.

BY FRIDAY AFTERNOON THE FRONT IS EXPECTED TO HAVE SETTLED OVER THE
SOUTHEAST PART OF THE AREA ALLOWING THE OLYMPIC PENINSULA TO BEGIN
TO DRAIN.

FOR THE MOST PART SATURDAY LOOKS DRY AS THE THU NIGHT FRI SYSTEM
SHOULD HAVE MOVED OFF TO THE EAST AND THE NEXT IN THE PARADE OF
SYSTEMS IS NOT EXPECTED UNTIL LATE SAT NIGHT INTO SUNDAY.  THUS IT
IS BEGINNING TO LOOK BETTER THAN WHAT WE CURRENTLY HAVE IN OUR
FORECAST AND I WILL LIKELY TWEAK THAT THIS AFTERNOON.  CERNIGLIA

.LONG TERM...THIS TIMEFRAME WILL BE AN ACTIVE ONE WEATHERWISE.  THE
UPPER RIDGE WILL SHIFT WELL EAST OF THE REGION ALLOWING THE PACIFIC
NW TO BE UNDER THE INFLUENCE OF THE DEEP TROUGH OFFSHORE.  THE
RESULT WILL BE A SERIES OF STORM SYSTEMS THE WILL RIDE UP THE EAST
SIDE OF THIS TROUGH AND ACROSS OUR AREA FROM SUNDAY ONWARD...LIKELY
THROUGH ALL OF NEXT WEEK.  IT WILL BE A WET PERIOD PROBABLY BEST
DESCRIBED AS...PERIODS OF RAIN WITH SOMEWHAT ABOVE NORMAL
TEMPERATURES.  SPECIFICS ARE QUITE LACKING AT THIS POINT BUT ONE OF
THESE STORM SYSTEMS COULD BE GOOD FOR STRONGER WINDS ACROSS PARTS OF
WESTERN WASHINGTON SUNDAY INTO TUE.  IT DEPENDS ON JUST HOW CLOSE TO
THE COAST THE STORMS PASS BY SO THIS WILL NEED TO BE WATCHED.  THERE
WILL BE ENOUGH RAIN THROUGH NEXT WEEK THAT BESIDE THE NORMAL LOCAL
HIGH WATER ISSUES THE THREAT OF LOCAL LANDSLIDES WILL REMAIN WITH
US.  CERNIGLIA

&&

.HYDROLOGY...UPPER LEVEL MOISTURE WILL BE AIMED AT THE CWA STARTING
THIS AFTERNOON.  SATELLITE DERIVED TOTAL PWAT VALUES INDICATED THAT
THIS MOISTURE...EMANATING FROM THE SUBTROPICS...CONTAINED 1 PLUS
INCHES OF WATER.  AN INCREASINGLY MOIST AIR MASS IN CONJUNCTION WITH
THE DEVELOPMENT OF STRONG /45 TO 50 KNOTS/ 850 MB FLOW AND RISING
SNOW LEVELS WILL TRANSLATE TO PERIODS OF HEAVY RAINS ON THE S AND SW
FACING SLOPES OF THE OLYMPICS AND N CASCADES.  RAINFALL AMOUNTS ON
THE S FACING SLOPES OF THE OLYMPIC RANGE...BY LATE FRI...ARE
EXPECTED TO BE IN THE 6 TO 8-INCH RANGE...WITH 3 TO 5 INCHES
POSSIBLE ON THE SW FACING SLOPES OF THE N CASCADES.  THIS AMOUNT OF
RAINFALL WILL INCREASE THE POTENTIAL FOR RIVER FLOODING...THUS A
FLOOD WATCH IS IN EFFECT.

THE BAROCLINIC BAND WILL STALL AND WEAKEN ACROSS THE SRN PORTION OF
THE CWA FRI NIGHT BEFORE LIFTING NWD DURING THE DAY SATURDAY AS HIGH
PRES BUILDS OVER THE REGION.

WILL NEED TO ALSO MONITOR THE USGS LANDSLIDE INDEX AS CONDITIONS
WERE FAVORABLE FOR LANDSLIDES...IF RAINFALL AMOUNTS DURING THE NEXT
24 HOURS OVER THE PUGET SOUND EXCEED 2 INCHES.  AT THIS TIME...IT
DID NOT APPEAR THAT THE PUGET SOUND WILL RECEIVE THIS AMOUNT OF
RAINFALL IN 24 HOURS.

BEYOND SATURDAY...THE NEXT WEEK WILL FEATURE NUMEROUS FAST-MOVING
WEATHER SYSTEMS THAT WILL BRING MODERATE RAINS...BUT DURATION OF
RAINFALL AND BREAKS BETWEEN WEATHER SYSTEMS SHOULD PRECLUDE
LARGE-SCALE FLOODING CONCERNS...ALTHOUGH SELECT...EASY TO FLOOD
RIVERS WILL BE UNDER THREAT OF RENEWED FLOODING.  COOLER WEATHER IS
ALSO EXPECTED FOR THE SECOND HALF OF NEXT WEEK WITH SNOW LEVELS
FALLING BACK DOWN BELOW PASS LEVEL.  COOLER WEATHER IS TYPICALLY
UNFAVORABLE FOR RIVER FLOODING.

FLOODING IS NOT EXPECTED ON THE GREEN RIVER FOR THE NEXT 10 DAYS.
