AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 AM PST TUE JAN 01 2008

.SYNOPSIS...A FRONT OFFSHORE WILL SPREAD CLOUDS OVER WESTERN
WASHINGTON TODAY AND BRING RAIN LATER TONIGHT INTO WEDNESDAY.
PERSISTENT SOUTHWEST FLOW ALOFT WILL BRING ONE SYSTEM AFTER ANOTHER
INTO THE REGION THROUGH SUNDAY. TEMPERATURES WILL BE MILD EARLY IN
THE WEEK. LATER IN THE WEEK LOWER TEMPERATURES AND SNOW LEVEL WILL
PREVAIL.

&&

.SHORT TERM...VAIL OF HIGHER CLOUDS ARE SPREAD ACROSS THE AREA THIS
MORNING AND AT THE MOMENT...FAIRLY DENSE. HINTS ON IR IMAGERY THAT
THIS LAYER WILL THINOUT LATER IN THE DAY ALLOWING SOME FILTERED
SUNSHINE TO BRIGHTEN THINGS UP. HOWEVER NOT ENOUGH TO WARRANT
CHANGING THE FORECAST WORDING FROM MOSTLY CLOUDY AS THAT WILL BE
ABOUT RIGHT. TEMPS WILL BE TRICKY TODAY AS THERE IS PLENTY OF WARM
AIR NOT THAT FAR OFF THE SURFACE. EVEN LOCATIONS NOT EXPOSED TO THE
EASTERLY FLOW ARE FAIRLY MILD AS SHOWN BY THE 33 DEGREE TEMPERATURE
AT 4200 FT ON MT BAKER. IN THE LOW LANDS WHERE THE EASTERLY BREEZES
HAVE PICKED UP OVERNIGHT THE TEMPERATURES JUMPED BACK INTO THE 40S
AFTER DROPPING INTO THE UPPER 20S TO LOWER 30S LAST EVENING. THIS
EASTERLY FLOW WILL HELP TO CONTINUE MIXING SOME OF THE WARMTH DOWN
WHICH WILL MAKE UPPER 40S A REALITY MANY AREAS THIS AFTERNOON. IF WE
ARE ABLE TO PLUG A BIT OF SUNSHINE INTO THE EQUATION EARLY THIS
AFTERNOON LOCAL HIGHS IN THE LOW 50S ARE NOT OUT OF THE QUESTION.

A WIND ADVISORY IS IN EFFECT FOR THE EAST PUGET SOUND
ZONE...BASICALLY FOR THE EASTERLY WINDS BLOWING OUT OF THE GAPS IN
THE CASCADE RANGE. THIS IS DUE TO THE STRONG CROSS-CASCADE GRADIENT
WE CURRENTLY HAVE...A LITTLE OVER 14 MBS SEA-EAT. THIS GRADIENT WILL
BE MAINTAINED THROUGH THE DAY SO WONT MESS WITH THE TIMING OR THE
WORDING AS WE WILL CONTINUE TO BLOW IN PLACES THROUGH THE DAY. I
HAVENT NOTICED ANY WIND ADVISORY CRITERIA WINDS JUST YET BUT
SEVERAL OBS ARE CLOSE WITH SUSTAINED WIND SPEEDS IN THE LOW 20S AND
PASS REPORTS REPORTING STRONG GUSTY WINDS. UPDATE...RECEIVED A
REPORT FROM A SPOTTER NEAR NORTH BEND WITH 35 MPH SUSTAINED AND
RECENT GUST TO 55 MPH...SMACK INTO ADVISORY CRITERIA.

THE FRONT OFFSHORE SPREADING THE CLOUDS OVERHEAD AND KICKING UP THE
WINDS WILL SLOWLY EDGE ITS WAY TO THE COAST THROUGH THIS TIME
WEDNESDAY. RAIN SHOULD REACH THE COAST EARLY THIS EVENING THEN
ARRIVE IN THE CENTRAL SOUND REGION SHORTLY AFTER MIDNIGHT. THE FRONT
WILL SWEEP ACROSS THE AREA DURING MORNING HOURS WITH THE
PRECIPITATION TAPERING TO SCATTERED RAIN SHOWERS WITH THE SUNSHINE
BREAKING THROUGH THE CLOUD COVER.

NEXT SYSTEM WILL BEGIN TO SWING UP FROM THE SW LATE WEDNESDAY NIGHT
FOR RAIN SPREADING NORTH ACROSS THE AREA AFTER MIDNIGHT AND
CONTINUING THROUGH THURSDAY FOR A FAIRLY WET DAY.  CERNIGLIA

.LONG TERM...FROM PREVIOUS DISCUSSION...HAVE KEPT THE BROAD BRUSH
IDEA AS MODELS BRING A SERIES OF SYSTEMS THROUGH WESTERN WASHINGTON.
A DEEP LOW IS OFTEN JUST OFFSHORE WITH THESE STORMS SO AREA WILL BE
WINDY OR BREEZY AT TIMES AS WELL AS WET. TEMPS RETURN TO MORE
SEASONAL NORMS AS HEIGHTS FALL. COULD BE A LITTLE SNOW AT TIMES BUT
TRYING TO PINPOINT IT CLEARLY PREMATURE AT THIS TIME. BURKE

&&

.AVIATION...UPPER LEVEL SYSTEM OVER THE GULF OF ALASKA WILL BRING AN
INCREASE IN CLOUDS TO THE AREA WITH STRONG SW FLOW ALOFT. COLD FRONT
WILL REACH THE COAST LATE THIS AFTERNOON WITH RAIN SPREADING INTO
THE INTERIOR BY MIDNIGHT.

.KSEA...MID/HIGH CLOUDS INCREASING TODAY WITH DRY CONDITIONS THROUGH
THIS EVENING. COLD FRONT WILL PASS THROUGH THE INTERIOR DURING THE
EARLY MORNING HOURS. WINDS OFF THE SURFACE STRONG WITH 40 KT AT
2000FT OFF RECENT ACARS SOUNDING...WILL KEEP LLWS IN THE FORECAST.
WINDS ALOFT 5-10K FT AT 00Z SW 40 TO 50 KT INCREASING TO 50 TO 60KT
BY 06Z. 33

&&

.MARINE...EXPECT STRONG OFFSHORE FLOW TODAY WITH GALE FORCE WINDS
ACROSS THE COASTAL WATERS AND THE WEST ENTRANCE OF THE STRAIT OF
JUAN DE FUCA. RAIN WILL DEVELOP OVER COASTAL WATERS THIS AFTERNOON
AS COLD FRONT MOVES EAST. FLOW WILL SWITCH TO ONSHORE OVERNIGHT AS
FRONT MOVES THROUGH WESTERN WA. 33
