AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
815 PM PDT THU AUG 7 2014

.SYNOPSIS...AREAS OF MORNING CLOUDS WILL BE FOLLOWED BY AFTERNOON
SUNSHINE FRIDAY. WEAKER ONSHORE FLOW WILL GIVE SUNSHINE AND WARMER
CONDITIONS ON SATURDAY. AN UPPER LEVEL RIDGE WILL BUILD INTO THE
REGION SUNDAY INTO MONDAY GIVING DRY CONDITIONS TO THE AREA AND VERY
WARM CONDITIONS IN THE INTERIOR.

&&

.SHORT TERM...A WEAK UPPER TROUGH WILL MOVE THROUGH WESTERN
WASHINGTON TONIGHT. BANDS OF CIRRUS ASSOCIATED WITH THE TROUGH ARE
MOVING THROUGH THE AREA NOW. AT THE SURFACE ONSHORE GRADIENTS ARE
SOMEWHAT STRONGER THAN LAST NIGHT. THE UPPER TROUGH COULD STIR UP
THE MARINE LAYER A BIT AND THE INCREASED ONSHORE FLOW WILL BRING
STRATUS A BIT FURTHER INLAND BY MORNING. MORNING CLOUDINESS COULD
LINGER LONGER THAN YESTERDAY BUT BY AFTERNOON BOTH THE STRATUS AND
THE CIRRUS SHOULD BE GONE...GIVING SUNNY SKIES. THE GRIDS AND
FORECASTS HAVE BEEN REFRESHED TO REFLECT THIS THINKING. HIGHS WILL
BE MAINLY IN THE 70S...WITH A FEW LOW 80S OVER THE INTERIOR.

HEIGHTS BUILD OVER THE WEEKEND AND ONSHORE SURFACE FLOW WILL BE
DIMINISHED. TEMPERATURES WILL RISE INTO THE LOW TO MID 80S SATURDAY
AND COULD REACH 90 OR SO ON SUNDAY. SKIES WILL BE MOSTLY SUNNY WITH
MORNING CLOUDINESS MOSTLY CONFINED TO THE COAST AND SOUTHWEST
INTERIOR. BURKE

.LONG TERM...PREVIOUS DISCUSSION...MONDAY WILL LIKELY BE A HOT DAY
IN THE INTERIOR. THEN...WITH A CHANCE THAT SOUTH TO SOUTHEAST FLOW
ALOFT WILL DEVELOP IN RESPONSE TO ENERGY DROPPING SOUTHWARD TO OUR
WEST...WE HAVE INTRODUCED A CHANCE OF HIGH BASED THUNDERSTORMS TO
THE CASCADES MONDAY AFTERNOON THROUGH TUESDAY NIGHT. MARINE MOISTURE
SHOULD INCREASE OVER THE EASTERN PACIFIC AND POSSIBLY AROUND THE
OLYMPIC PENINSULA...SO LOWER TEMPERATURES AND A CHANCE OF LIGHT RAIN
OR DRIZZLE IS INDICATED THERE FOR MONDAY NIGHT INTO TUESDAY NIGHT.
TEMPERATURES IN THE INTERIOR OF WESTERN WASHINGTON WILL LIKELY FALL
TUESDAY INTO WEDNESDAY.

HIGHER TEMPERATURES MAY DEVELOP TOWARD THE END OF NEXT WEEK AS
RIDGING ALOFT AND OFFSHORE FLOW POSSIBLY DEVELOPS PER LONG RANGE
MODEL SOLUTIONS. ALBRECHT

&&

.AVIATION...AN UPPER TROUGH OVER THE OFFSHORE WATERS WILL REACH THE
COAST LATE TONIGHT AND MOVE INLAND FRIDAY. SOUTHWEST FLOW ALOFT OVER
WESTERN WASHINGTON AHEAD OF THE TROUGH WILL VEER TO WESTERLY BEHIND
IT. LOW LEVEL ONSHORE FLOW WILL CONTINUE. THE AIR MASS WILL BE
STABLE WITH MOISTURE IN THE MARINE LAYER.

AREAS OF STRATUS ALONG THE COAST THIS EVENING...WITH BASES AROUND
1500 FT...WILL BECOME SOLID ALONG THE COAST THIS EVENING AND LOWER
SOMEWHAT OVERNIGHT. STRATUS WILL MOVE INLAND THROUGH THE STRAIT OF
JUAN DE FUCA AND THE CHEHALIS GAP OVERNIGHT AS WELL...AND MUCH OF
THE WESTERN WASHINGTON INTERIOR LOWLANDS WILL HAVE IFR OR LOW-END
MVFR CONDITIONS ROUGHLY 12Z-18Z. IN ADDITION SOME HIGH CLOUD COVER
ASSOCIATED WITH THE UPPER TROUGH WILL BE OVER THE AREA TONIGHT AND
FRIDAY MORNING.

KSEA...NORTHWEST 4-8 KT...BECOMING SOUTH OVERNIGHT...THEN NORTHWEST
AGAIN LATE FRIDAY AFTERNOON. STRATUS SHOULD AFFECT KSEA WITH IFR OR
LOW=END MVFR CEILINGS ROUGHLY 12Z-18Z.   MCDONNAL

&&

.MARINE...THE PERSISTENT PATTERN OF HIGH PRESSURE OVER THE OFFSHORE
WATERS AND LOWER PRESSURE INLAND WILL MAINTAIN ONSHORE FLOW THROUGH
THE WEEKEND. WESTERLY WINDS THROUGH THE STRAIT OF JUAN DE FUCA ROSE
MORE THAN EXPECTED...AND THE SMALL CRAFT ADVISORY WAS UPGRADED TO A
GALE WARNING EARLY THIS EVENING. SMALL CRAFT ADVISORIES ARE IN
EFFECT FOR ADMIRALTY INLET AND THE NORTHERN INLAND WATERS TONIGHT AS
WELL.
