AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
325 AM PDT FRI SEP 1 2006

.SYNOPSIS...A STRONG UPPER LEVEL RIDGE OVER WESTERN WASHINGTON WILL
MOVE SLOWLY EAST BY SATURDAY. DEVELOPING LOW LEVEL OFFSHORE FLOW
CAUSED BY THE RIDGE WILL PUSH TEMPERATURES WELL ABOVE NORMAL TODAY
AND SATURDAY. LOW LEVEL ONSHORE FLOW WILL DEVELOP ALONG THE COAST
LATE SATURDAY AND SPREAD INLAND BY SUNDAY NIGHT...WITH AREAS OF LOW
CLOUDS AND FOG AND COOLER TEMPERATURES GRADUALLY SPREADING INLAND
WITH THE ONSHORE FLOW. HIGH PRESSURE TO THE EAST AND WEAKER ONSHORE
FLOW WILL RESULT IN DRY WEATHER AND TEMPERATURES NEAR NORMAL EARLY
NEXT WEEK.

&&

.SHORT TERM...A STRONG UPPER LEVEL RIDGE CENTERED NEAR THE COAST
THIS MORNING WILL MOVE GRADUALLY EAST...REACHING W MT ON SATURDAY.
WELL DEVELOPED LOW LEVEL EASTERLY OFFSHORE FLOW WILL ALLOW A STRONG
SURFACE THERMAL TROUGH TO FORM NEAR THE COAST TODAY AND
SATURDAY...THEN MOVE INLAND NEAR THE CASCADES ON SUNDAY. THE MAIN
PROBLEMS THIS FORECAST PACKAGE ARE THE MAGNITUDE AND DISTRIBUTION OF
MAX TEMPS THROUGH THE WEEKEND...AND WHEN AND HOW STRONG A SW MARINE
PUSH WILL DEVELOP THIS WEEKEND.

00Z NAM-WRF AGREES WITH THE 00Z GFS ON THE LARGE SCALE FEATURES SO
HAVE LEANED TOWARD THE NAM-WRF IN HANDLING THE DETAILS OF THE
OFFSHORE FLOW AND THE DEVELOPING SW MARINE PUSH. WITH THE
DEVELOPMENT OF THE THERMAL TROUGH ALONG THE COAST...THIS LOOKS MORE
LIKE A CLASSIC SW PUSH WITH STRATUS SPREADING UP THE OREGON COAST
AND REACHING HOQUIAM SATURDAY EVENING. LEANING HARD ON THE 00Z
NAM-WRF HERE. COULD SEE SOME SHALLOW STRATUS/FOG SPREADING INTO NEAR
SHELTON BY SUNDAY MORNING...BUT WITH THE THERMAL TROUGH STILL W OF
THE CASCADES SUNDAY MAX TEMPS INLAND WILL REMAIN QUITE WARM. A SOLID
MARINE PUSH SHOULD DEVELOP SUNDAY NIGHT FOR MORNING
CLOUDS/FOG/COOLER ON LABOR DAY.

CASCADE RAWS SITES SHOW EASTERLY OFFSHORE FLOW RAMPING UP THIS
MORNING AND DEW POINTS DROPPING RAPIDLY SO EASTERLY FLOW IS ON.
OTH-SEA GRADIENT IS A SKY HIGH -7.5.  GFS MOS TEMPERATURES LOOK TOO
COLD FOR TODAY AND SATURDAY...ESPECIALLY FOR THE COAST TODAY. ETA
MOS IS BETTER BUT STILL ON THE COLD SIDE. NEITHER MOS SUITE QUITE
CAPTURES THE DISTRIBUTION OF THE WARMING SO MAX/MIN TEMP GRIDS
SUFFERED A LOT OF HANDS-ON EDITING THIS MORNING. WILL HOPE FOR THE
BEST BUT OVER ALL THE MAX TEMPS WERE JACKED UP TO THE LOWER TO MID
80S TODAY WITH THE COAST JUST AS WARM AS THE INTERIOR. HOTTEST PARTS
OF THE INTERIOR SATURDAY SHOULD BE NEAR 90. IMMEDIATE COAST SHOULD
SEE A COOLING LATER IN THE AFTERNOON AS ONSHORE FLOW STARTS TO
DEVELOP. A VERY SHALLOW PUSH SHOULD PUSH PART WAY INLAND SATURDAY
DAY NIGHT...BUT THIS SHALLOW COOLING LIKELY WONT HAVE A STRONG
EFFECT ON MAX TEMPS OVER THE INTERIOR ON SUNDAY. HAVE SHAVED A FEW
DEGREES OFF...BUT STILL QUITE WARM SUNDAY. KAM

.LONG TERM...PER ABOVE A STRONG SW PUSH SHOULD DEVELOP SUNDAY NIGHT
WITH MOTHER NATURES AIR CONDITIONING COOLING THINGS DOWN FOR LABOR
DAY. FORECASTS ARE BASED STRONGLY ON THE 00Z NAM-WRF TIMING WHICH
OVERALL SIMILAR TO THE GFS WITH RESPECT TO THE LARGE SCALE FEATURES.
GFS MAINTAINS THE UPPER LEVEL RIDGE OVER W MT EARLY NEXT
WEEK...ALLOWING A WEAKENING UPPER LEVEL TROUGH TO REACH THE COAST
ABOUT TUESDAY AND MAYBE ANOTHER ONE LATE THURSDAY. MAIN PRODUCT WILL
BE WESTERLY ONSHORE FLOW...SO THERE SHOULD BE AFTERNOON CLEARING TO
GO ALONG WITH MORE SEASONABLE TEMPERATURES. KAM

&&

.AVIATION...RIDGE OVERHEAD WITH MODERATE OFFSHORE FLOW THROUGH SAT.
THEREFORE CLEAR WITH A N-E LOW LEVEL FLOW. DECENT RIDGETOP EASTERLY
WINDS ACROSS THE CASCADES AS WELL.

AT KSEA...CLEAR SKIES. N-NE WIND 10-15 KT...MORE NE AT NIGHT AND N
DURING THE AFTERNOON. CERNIGLIA

.SEW WATCHES/WARNINGS/ADVISORIES...SMALL CRAFT ADVISORY W ENTRANCE
TO THE STRAIT.
