AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
840 AM PST FRI NOV 3 2006

.SYNOPSIS...A WEATHER SYSTEM WILL MOVE THROUGH WESTERN WASHINGTON
TODAY. THE NEXT VIGOROUS FRONTAL SYSTEM WILL ARRIVE SATURDAY
AFTERNOON AND EVENING. A THIRD WILL REACH THE AREA BY SUNDAY NIGHT
AND DRAG SLOWLY THROUGH THE AREA ON MONDAY. IT WILL BE WINDY AT
TIMES.

&&

.SHORT TERM...AN AREA OF 50KT H850 WINDS MOVES THROUGH WITH THE
SHORT WAVE TODAY...GALES COAST THIS MORNING SPREAD TO THE EAST
ENTRANCE AND ADMIRALTY INLET LATE THIS MORNING. THIS FIRST WAVE HAD
SOMETHING AROUND A 997MB LOW OFF VANCOUVER ISLAND WHICH BREAKS UP AS
IT CROSSES THE ISLAND SO THIS WILL BE TYPICAL MESOLOW ENHANCEMENT
FOR ADMIRALTY AREA. ANOTHER WAVE PUTS A 995MB LOW INTO NORTHERN
VRISL 12Z SAT (ON THE MM5NAM) AND MAINTAINS BREEZY RAINY WEATHER
OVER WESTERN WA. CLOSE ON THE HEELS OF THAT IS A 1002MB LOW AIMED AT
OUR COAST...AND THE MM5NAM PUTS GALES BACK INTO OUR COASTAL WATERS
BY SAT AFTERNOON...MOSTLY FROM DESTRUCTION SOUTH. FROPA WITH THIS
SYSTEM IS THROUGH PUGET SOUND AROUND 7PM SATURDAY EVENING AS THE LOW
DEEPENS TO 998MB AND MOVES INTO SOUTHERN B.C. THE WINDS AT H850 ARE
AROUND 60KTS WITH THIS WAVE. THE SYSTEM MOVING THROUGH TODAY DOES
NOT SEEM TO HAVE GOOD UPPER LEVEL SUPPORT OR A STRONG JET STREAK.
THE SYSTEM COMING THROUGH SATURDAY AFTERNOON LOOKS MORE INTERESTING
AND SHOULD BE A WINDIER SYSTEM AT THE SURFACE. QUICK LOOK AT MM5GFS
SUGGESTS THE NEXT ROUND OF SOUTHERLY GALES OVER ALL OF THE COASTAL
WATERS BY 18Z SAT...AND FOR THE INLAND WATERS FROM POINT WILSON
NORTH EARLY SAT AFTERNOON...THEN FROPA.

MODERATE AND LOCALLY HEAVY RAIN IN THE MOUNTAINS THROUGH TONIGHT
WITH THIS FIRST SYSTEM...ESPECIALLY OLYMPICS AND NORTH CASCADES.
JUST LIGHT PRECIP SATURDAY MORNING...THEN HEAVY RAIN INTO THE
OLYMPICS BY MIDDAY SATURDAY...WITH A 6 TO 9 HOUR PERIOD OF HEAVY
RAIN DRAGGING THRU THE MOUNTAINS WITH THAT FRONTAL SYSTEM. THE
RIVERS WILL BE FILLING UP THIS WEEKEND WHICH SETS THE STAGE FOR
POTENTIAL FLOODING EARLY NEXT WEEK. ESF LOOKS GOOD FOR NOW. MM

.LONG TERM...THE BAROCLINIC ZONE THAT SETS UP OVER THE AREA SUNDAY
NIGHT AND MONDAY SHOULD GENERATE THE MOST RAIN SO FAR. THERE IS A
160KT JET AT H250 IN PLACE (POSSIBLY AS STRONG AS 180KTS INTO THE
B.C. COAST 00Z TUE) AND THE GFS ALSO SHOWS A STEADY 50-70KT SWLY
PLUME AT H850 MORE OR LESS POINTED AT WESTERN WA FOR 24HRS. FROPA IS
MONDAY EVENING. MM

&&

.AVIATION...RAIN AT TIMES TODAY...CEILINGS GENERALLY 5K-7K FT WITH
SOME AREAS BELOW 500 FEET IN THE HEAVIER RAIN BANDS. STRONG SE SFC
GRADIENTS AND 850MB FLOW WILL SUPPORT INCREASED SE WINDS THROUGHOUT
AREA TODAY AND TONIGHT. WIND AT KSEA SE 9-12 KT RISING TO 12-15 KT
AROUND NOON. COOK

.SEW WATCHES/WARNINGS/ADVISORIES...GALE WARNING COAST...WEST
