.SYNOPSIS...A STRONG SURFACE LOW DEVELOPING OFFSHORE WILL HEAD
TOWARD THE STATE ON THURSDAY WITH VERY WINDY CONDITIONS DEVELOPING
ALONG THE COAST AND NORTH INTERIOR...WITH WINDY CONDITIONS
ELSEWHERE. ANOTHER SYSTEM WILL MOVE ONSHORE FRIDAY WITH RAIN AND
SHOWERS ACROSS THE AREA. AN UPPER LEVEL RIDGE WILL BUILD OVER THE
AREA THROUGH THE LATER HALF OF THE WEEKEND WITH THE BEST CHANCE OF
RAIN ACROSS THE NORTHERN PORTION OF THE STATE.

&&

.SHORT TERM...UPPER LEVEL TROUGH IS MOVING THROUGH THE AREA THIS
AFTERNOON WITH A FEW SHOWERS ACROSS THE AREA. THERE MAY BE A FEW
LIGHTING STRIKES WITH SOME OF THE STRONGER CELLS. SHOWERS WILL
DIMINISH DURING THE EVENING HOURS WITH A BRIEF BREAK IN THE WEATHER
OVERNIGHT.

THE PACIFIC STORM OFFSHORE CONTINUES TO PUSH ALONG AND IS NOW
LOCATED ABOUT 600 MILES OFF THE WASHINGTON COAST. LATEST 12Z MODELS
BRING THIS SYSTEM TO 130W BY 12Z THU WITH A THE GFS BRINGING THE SFC
PRESSURE DOWN TO 980 MB...AND THE NAM SLIGHTLY HIGHER AT 982 MB. AT
THIS POINT SHOULD START TO SEE STRONG SOUTHEAST WINDS ALONG THE
COAST AND ALSO THE NORTH INTERIOR. WINDS SPEEDS ACROSS THESE AREAS
ARE EXPECTED TO BE IN THE 30 TO 40 MPH RANGE WITH GUSTS UP TO 60
MPH.

BY THE AFTERNOON...THE GFS CONTINUES TO FAVOR A MORE NORTHERLY
TRACK WITH THE LOW AND WILL BRING IT INTO CENTRAL VANCOUVER ISLAND.
THE NAM IS FURTHER SOUTH WITH THE TRACK MOVING THROUGH THE OLYMPIC
PENINSULA AND ON OVER TO THE SAN JUANS. BOTH TRACKS WILL SWITCH THE
WINDS ON THE COAST AND STRAIT TO THE WEST WITH STRONG SOUTH TO SW
WINDS ACROSS THE INTERIOR. THE STRONGEST WINDS IN THE PUGET SOUND
AREA WILL OCCUR DURING THE LATE AFTERNOON AND EARLY EVENING. AS FOR
HOW STRONG...IT ALL DEPENDS ON HOW TIGHT THE SOUTH TO NORTH PRES
GRADIENT IS...WHICH DEPENDS ON THE TRACK OF THIS SYSTEM AS IT MOVES
ONSHORE. AT THIS TIME WE ARE EXPECTING SOUTH TO SW WINDS 25 TO 35
MPH WITH GUSTS TO 50 MPH FOR THE INTERIOR. MAY SEE HIGHER WINDS IN
HOOD CANAL. ASIDE FROM THE STRAIT...WILL SEE WINDS ACROSS THE AREA
DIMINISH DURING THE EVENING FROM 03Z TO 06Z AS THIS SYSTEM EXITS THE
REGION. IN ADDITION...THIS SYSTEM WILL ALSO BE PRODUCING MODERATE
RAINFALL ACROSS THE COAST AND OLYMPICS. FREEZING LEVELS ACROSS THE
CASCADES WILL BE AROUND THE 4000 FT LEVEL WITH A FEW INCHES OF
ACCUMULATION POSSIBLE.

ON FRIDAY...ANOTHER SYSTEM WILL MOVE INTO THE AREA...BUT IT LOOKS
MUCH WEAKER...IN TERMS OF STRONG WINDS ACROSS THE AREA. STILL
EXPECTING RAIN AND SHOWERS ACROSS THE AREA THOUGH AS A COLD FRONT
AND UPPER LEVEL TROUGH MOVES THROUGH. WET WEATHER IS EXPECTED INTO
THE FIRST PART OF THE WEEKEND. 33

.LONG TERM...MODELS BUILD IN A RIDGE OVER THE PACNW ON SUNDAY
ALTHOUGH A FRONT WILL STILL SLIDE IN UNDERNEATH WITH THE BEST
CHANCES OF RAIN LOCATED ACROSS THE WESTERN ZONES. THIS RIDGE WILL
STRENGTHEN EARLY NEXT WEEK AS 593 RIDGE BUBBLE FORMS OVER THE
PACIFIC OFF THE CALIFORNIA COAST. THIS RIDGE WILL FORCE PRECIP
FURTHER NORTH WITH DRIER CONDITIONS ACROSS WESTERN WASHINGTON. WILL
SEE TEMPS SLOWLY CLIMBING BACK INTO THE LOW 60S ACROSS THE INTERIOR
BY MID WEEK. 33

&&

.AVIATION...FRONTAL CLOUDS HAVE MOVED OUT OF THE AREA BUT CUMULUS
HAS FILLED IN NICELY WITH SCATTERED CONVECTION. A FEW LIGHTNING
STRIKES NOTED NEAR GIG HARBOR. SHOWERS SHOULD END AFTER 03Z OR SO.
INCREASING CLOUD TREND LATER TONIGHT AS NEXT BIG SYSTEM APPROACHES.
WIND AT KSEA SW 10-15 KT THIS EVENING...SWITCHING TO SE 4-8 KT AFTER
06Z. CHB

&&

.MARINE...GALES ISSUED ALL WATERS...STORM FOR COAST. WINDS WILL
INCREASE THROUGH THE NIGHT AS LOW OFFSHORE DEEPENS AND MOVES NE.
EXPECTED TRACK IS INTO CENTRAL VANCOUVER ISLAND...AND SOME FILLING
IS ALSO EXPECTED. NEVERTHELESS SHOULD BE A VERY WINDY EVENT FOR
MARINE AREAS. THE COAST WILL PROBABLY REACH 50 KT WITH THE
SOUTHEASTERLIES AHEAD OF THE SYSTEM...THEN HIGH END GALES WITH
