AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
330 AM PDT MON SEP 5 2011

.SYNOPSIS...HIGH PRESSURE ALOFT WILL GIVE DRY WEATHER AND ABOVE
NORMAL HIGHS FOR THE NEXT WEEK. LOW LEVEL OFFSHORE FLOW WILL DEVELOP
LATER THIS WEEK...ALLOWING HIGHS TO WARM TO NEAR RECORD LEVELS.

&&

.SHORT TERM...A BROAD UPPER LEVEL RIDGE...CENTERED OVER THE INNER
MOUNTAIN WEST TODAY...WILL BUILD WESTWARD TUESDAY AND WEDNESDAY.
WEAK LOW LEVEL ONSHORE FLOW WILL PREVAIL TODAY. THIS WILL COOL HIGHS
A FEW DEGREES COMPARED TO YESTERDAY BUT TEMPERATURES WILL REMAIN A
BIT ABOVE NORMAL. COASTAL STRATUS AND FOG EARLY THIS MORNING LOOKS
QUITE SHALLOW AND DO NOT EXPECT IT TO SPREAD VERY FAR INLAND BEFORE
BURNING BACK TO THE BEACHES. THE LOW LEVEL ONSHORE FLOW WILL
GRADUALLY BECOME MORE NORTHERLY TONIGHT AND TUESDAY...IN RESPONSE TO
A THERMAL TROUGH BUILDING NORTHWARD ALONG THE COAST AND THE UPPER
RIDGE BUILDING OVER THE AREA. EXPECT ONLY MINIMAL STRATUS WILL
SPREAD PARTIALLY INLAND UNDER THIS SCENARIO AND IT MIGHT EVEN BE A
BIT HIT AND MISS AT THE COAST. WITH THE WEAKENING ONSHORE FLOW AND
BUILDING UPPER HEIGHTS...HIGHS ON TUESDAY WILL BE A FEW DEGREES
WARMER THAN MONDAY. THESE TRENDS WILL ALL CONTINUE INTO WEDNESDAY...
BUILDING UPPER HEIGHTS...INCREASING OFFSHORE FLOW...AND WARMING AT
THE LOW LEVELS. IN OTHER WORDS...WEDNESDAY SHOULD BE SUNNY AND
WARMER WITH HIGHS WELL ABOVE NORMAL. SCHNEIDER

.LONG TERM...A STRONG UPPER  LEVEL RIDGE WILL BE IN CONTROL THURSDAY
THROUGH SUNDAY FOR DRY WEATHER AND WELL ABOVE NORMAL HIGHS. WHILE
THE MODELS ARE BEGINNING TO HINT THAT RECORD HEAT IS NOT QUITE AS
LIKELY...IT IS A PRETTY GOOD BET THIS WILL BE A LONG WARM SPELL...
ESPECIALLY FOR SEPTEMBER. SCHNEIDER

1900 UTC.

KSEA...VFR CONDITIONS WILL PREVAIL. WINDS WILL BE LIGHT AND VARIABLE
