AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
245 PM PDT THU JUL 12 2007

.SYNOPSIS...WEAK ONSHORE FLOW AND BANDS OF CLOUDS WILL MODERATE
TEMPERATURES THROUGH THE WEEKEND. SOUTHERLY FLOW ALOFT WILL BRING
ADDED MOISTURE AND A CHANCE OF THUNDERSTORMS TONIGHT THROUGH FRIDAY.
A SERIES OF TROUGHS WILL BRING COOLER TEMPERATURES AND A FEW SHOWERS
TO THE AREA OVER THE WEEKEND AND INTO NEXT WEEK.

&&

.SHORT TERM...THICK BAND OF MID AND HIGH LEVEL CLOUDS NOW MOVING
NORTH OUT OF THE SEATTLE AREA. THIS BAND DEPRESSED TEMPERATURES AND
ALSO BROUGHT A FEW SPRINKLES BUT TEMPS APPEAR TO BE REBOUNDING.
HIGHS MAINLY IN THE 80S ARE STILL ON TRACK THIS AFTERNOON. PRETTY
CLEAR SKIES BEHIND THE BAND OF CLOUDS AND THUNDERSTORMS LOOK LIKE
THEY WILL TAKE AWHILE TO DEVELOP. SOME CONVECTION STARTING OVER THE
OREGON CASCADES BUT WILL PROBABLY BE AFTER MIDNIGHT BEFORE ANYTHING
POPS OVER WASHINGTON. CONVECTION COULD BREAK OUT ANYWHERE BUT MAIN
FOCUS WILL BE OVER THE CASCADES.

KEPT BASIC FORECAST IN PLACE BUT BOOSTED AFTERNOON HIGHS A BIT OVER
THE NEXT TWO DAYS. HEIGHTS REMAIN IN THE 580S AND TEMPS SHOULD ALSO
BE IN THE 80S WITH A SLOW COOLING TREND AS ONSHORE FLOW HAS MORE OF
AN EFFECT. HIGHS WILL PERHAPS REACH ONLY THE 70S ON SUNDAY AS TROUGH
FAR OFFSHORE BEGINS TO APPROACH AND HEIGHTS FALL. MORE ONSHORE FLOW
THEN TOO AND A WEAK WEATHER SYSTEM BRINGS A CHANCE OF SHOWERS. BURKE

.LONG TERM...HAVE KEPT THE FORECAST DRY THROUGH THE EXTENDED PERIOD
EVEN THOUGH MODELS HAVE A DEEP TROUGH OFFSHORE AND OCCASIONALLY
BRING SHOWERS THROUGH WESTERN WASHINGTON. IN DEFERENCE TO THIS
PERSISTENT MODEL FEATURE HAVE LOWERED AFTERNOON HIGHS TO THE 70S AND
EVEN THE 60S...BUT NO CALL FOR SHOWERS YET. BURKE

&&

.AVIATION...MID AND HIGH CLOUDS ASSOCIATED WITH A WEAK...UPPER LEVEL
SHORT WAVE CONTINUED TO MOVE NWD AND IS EXPECTED TO COMPLETELY EXIT
THE AREA BY 02Z. SOME SPRINKLES WERE ASSOCIATED WITH THIS FEATURE.

MEANWHILE...STRATUS...CIGS NEAR 015...LINGERED OVER THE COAST AND
WILL SPREAD BACK INLAND TONIGHT. THE QUESTIONS WERE HOW FAST THE LOW
CLOUDS WILL SPREAD INLAND...HOW FAR IT WILL PENETRATE...AND WHAT
WILL THE BASES BE. AT THIS TIME...SUSPECT THAT THE CLOUDS WILL ROLL
IN ACROSS THE PUGET SOUND AROUND 09Z. CIGS SHOULD BE NEAR 015 ON THE
COAST AND GENERALLY 006 TO 010 INLAND. TOPS SHOULD START OUT 015-020
AND THEN DEEPEN TO 025-030 BY 18Z FRI.

CONCERNING TSTM POTENTIAL...THE BEST CHANCE WILL BE AFTER 09Z...AND
MAINLY OVER THE CASCADES AND OLYMPICS. HOWEVER WOULD NOT RULE OUT A
THREAT ANYWHERE ELSE. THE TSTMS WILL BE ISOLATED IN COVERAGE.

AT KSEA...WINDS WILL REMAIN SW TO 7 KNOTS. VFR CONDITIONS TIL ABOUT
09Z...THEN LOW CLOUDS...CIGS NEAR 1K FT...ARE EXPECTED TO ROLL IN
FROM THE SW. THERE IS A 10 PERCENT CHANCE OF A TSTM AT THE SITE. ANY
TSTM THAT DEVELOPS TO THE S OF THE AIRPORT LATE TONIGHT OR FRI
MORNING WILL HAVE THE POTENTIAL TO MOVE ACROSS THE COMPLEX PROVIDED
THAT IT DOES NOT DISSIPATE BEFOREHAND.
