AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
1001 PM PDT THU AUG 13 2015

.SYNOPSIS...A LOW PRESENTLY OFF THE FAR NORTHERN CALIFORNIA COAST
WILL SLOWLY DRIFT NORTH OVERNIGHT. THIS LOW WILL MOVE ACROSS THE
AREA FRIDAY AFTERNOON AND OVER CANADA FRIDAY NIGHT. A WEAK LOW
PRESSURE SYSTEM WILL REMAIN OVER THE REGION ON SATURDAY. HIGH
PRESSURE ALOFT WILL PREVAIL OVER THE AREA ON SUNDAY.

&&

.SHORT TERM...
THE PESKY UPPER LEVEL LOW OFF THE FAR NORTHERN CA COAST WILL
SLOWLY DRIFT NORTH OVERNIGHT. THE BEST CHANCE OF SHOWERS OR TSTMS
WILL BE OVER THE SOUTHERN PART OF THE CWA LATE TONIGHT...THUS
REMOVED THE THREAT FROM THE NORTHERN ZONES. OTHERWISE...THE MAIN
IMPACT THE LOW WILL HAVE ON OUR WEATHER OVERNIGHT WILL BE TO
STRENGTHEN THE ONSHORE PRESSURE GRADIENT AND DEEPEN THE MARINE
LAYER. THE STRATUS WAS PRESENTLY AT THE DOORSTEP OF SHELTON AND
WILL CONTINUE SURGING NORTHWARD OVERNIGHT.

LOOK FOR THE UPPER LOW TO MOVE OVER NORTHWEST OREGON FRIDAY
MORNING. THE CURRENT FORECAST HAS THE TSTM THREAT CONFINED TO THE
CASCADES ON FRI BUT CANNOT COMPLETELY RULE OUT ISOLATED ELEVATED
/OCCURRING ABOVE THE MARINE LAYER/ TSTMS ELSEWHERE FRI MORNING.
ALREADY STARTING TO SEE LIGHTNING STRIKES OFF THE OREGON COAST...
IN THE NORTHEAST QUADRANT OF THE LOW CIRCULATION. THE LOW IS
FORECAST TO MOVE ACROSS THE CWA FRI AFTERNOON. THEREFORE...THE
TSTM THREAT WILL LIKELY BECOME CONFINED TO NEAR THE CASCADE
CREST BY LATE FRI AFTERNOON. THE MAIN MESSAGE IS THAT TEMPS ON FRI
WILL LIKELY BE WELL BELOW NORMAL ACROSS MUCH OF THE AREA.

THE LOW IS ANTICIPATED TO MOVE INTO SOUTHEAST BRITISH COLUMBIA FRI
EVENING. THIS WILL RESULT THE FLOW ALOFT BECOMING WESTERLY OVER
THE AREA. THIS COMBINED WITH CONTINUED LOW LEVEL ONSHORE FLOW AND
A DEEP MARINE LAYER WILL SERVE TO END ANY RISK OF TSTMS OVER THE
CASCADES BY LATE IN THE DAY FRI...IF THE MODELS TIMING IS CORRECT.
LOOK FOR A GRADUALLY DIMINISHING THREAT OF SHOWERS FRI NIGHT AS
THE LOW MOVES FARTHER AWAY FROM THE CWA.

A WEAK UPPER LEVEL TROF WILL REMAIN OVER THE PACIFIC NORTHWEST ON
SATURDAY FOR A THREAT OF SHOWERS OVER MAINLY THE NORTH CASCADES. A
WEAKENING ONSHORE PRESSURE GRADIENT WILL ALLOW TEMPS TO REBOUND
TO NEAR NORMAL.

AN UPPER LEVEL RIDGE WILL PREVAIL ON SUNDAY FOR A RETURN TO
DRY...SUNNIER WEATHER WITH SLIGHTLY ABOVE NORMAL TEMPS.

.LONG TERM FROM THE PREV DISCUSSION...
MEDIUM RANGE MODELS CONTINUE TO GENERALLY AGREE ON THE NEXT
SYSTEM MOVING SOUTH ALONG THE BRITISH COLUMBIA COAST INTO WESTERN
WASHINGTON ON MONDAY. THEY CONTINUE TO DIFFER ON THE TIMING OF THE
SYSTEM WITH THE 12Z ECMWF REMAINING FASTER...BRINGING PRECIP TO
THE NORTH WASHINGTON COAST MONDAY MORNING...WHILE THE GFS WAITS
UNTIL MONDAY AFTERNOON. BOTH MODELS HAVE BACKED OFF PRECIPITATION
COVERAGE...KEEPING WITH THE IDEA OF SHOWERS AS THE THE SYSTEM WORK
THROUGH THE AREA. BEYOND THIS EXPECT A SEASONABLE PATTERN WITH
MORNING CLOUDS AND AFTERNOON CLEARING AND NEAR NORMAL
TEMPERATURES.

&&

.AVIATION...AN UPPER LOW OFFSHORE NORTHERN CALIFORNIA WILL LIFT
NORTH/NORTHEAST TONIGHT AND FRIDAY...MOVING OVER WESTERN
WASHINGTON FRIDAY AFTERNOON. AIR MASS UNSTABLE WITH HIGH LEVEL
MOISTURE. LOW CLOUDS AT THE COAST WILL PUSH INLAND TONIGHT. THE
AIR MASS WILL BE MOIST AT ALL LEVELS ON FRIDAY.

KSEA...HIGHS CLOUDS AT TIMES TONIGHT. LOW CLOUDS SHOULD REACH THE
TERMINAL FRIDAY MORNING AND PERSIST FOR MOST OF THE DAY WITH
SHOWERS. AN ISOLATED THUNDERSTORM CANNOT BE COMPLETELY RULED OUT
FRIDAY BUT THE RISK IS TOO LOW TO MENTION IN THE TAF. LIGHT
NORTHWEST WIND THIS EVENING WILL BECOME SOUTH AND INCREASE TO 10 TO
20 KNOTS ON FRIDAY. SCHNEIDER

&&

.MARINE...ONSHORE FLOW WILL PREVAIL FOR THE NEXT SEVERAL DAYS WITH
HIGH PRESSURE OFFSHORE AND LOWER PRESSURE INLAND. THE ONSHORE FLOW
WILL BE STRONGEST FRIDAY NIGHT. SMALL CRAFT ADVISORY WEST WINDS
WILL OCCUR IN THE CENTRAL AND EAST STRAIT TONIGHT AND AGAIN FRIDAY
NIGHT. THERE IS A CHANCE WEST WINDS IN THE STRAIT COULD HIT GALE
FRIDAY NIGHT. SCHNEIDER

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...SMALL CRAFT ADVISORY IN EFFECT TIL 5 AM FRIDAY FOR THE
	 CENTRAL AND EASTERN STRAIT OF JUAN DE FUCA.
