AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
914 AM PDT SAT NOV 2 2013
.SYNOPSIS...A 994 MB LOW WILL MOVE ACROSS NORTHWEST WASHINGTON THIS
MORNING AND OVER BRITISH COLUMBIA THIS AFTERNOON. STRONG PRESSURE
RISES BEHIND THE LOW WILL BRING WINDY CONDITIONS TO MOST OF WESTERN
WASHINGTON THROUGH THIS EVENING. HIGH WINDS ARE STILL POSSIBLE TODAY
IN SOME AREAS. AREAS OF LIGHT RAIN THIS MORNING WILL TAPER OFF TO
SCATTERED SHOWERS AS THE LOW MOVES EAST. DRIER NORTHWEST FLOW ALOFT
WILL BRING A MOSTLY DRY DAY ON SUNDAY. A WEAK OCCLUDED FRONT WILL
BRING SOME LIGHT RAIN LATE MONDAY AND MONDAY NIGHT. A STRONGER
WEATHER SYSTEM MAY REACH THE AREA AROUND MID-WEEK.
&&
.SHORT TERM...A 994 MB SURFACE LOW REACHED THE N WA COAST NEAR LA
PUSH AROUND 7 AM THIS MORNING AND IS NOW HEADED INLAND ENE FOR A
DATE WITH VANCOUVER AROUND 2 PM. MODELS ARE CONSISTENT IN SHOWING
STRONG PRESSURE GRADIENTS DEVELOPING OVER W WA BEHIND THE LOW AS IT
MOVES INLAND. FORECASTS REMAIN UNCHANGED WITH HIGH WIND FORECAST FOR
THE COAST...N INTERIOR...STRAIT OF JUAN DE FUCA...HOOD CANAL...AND
EVERETT. HIGH WIND HAS ALREADY VERIFIED ON THE COAST AT DESTRUCTION
ISLAND...AND PRESSURE GRADIENTS ARE COMING UP THROUGH PUGET
SOUND...WITH WINDS ALREADY IN THE ADVISORY RANGE. PER THE RUC13 W
WINDS THROUGH THE STRAIT PROBABLY WILL NOT INCREASE UNTIL MIDDAY.
THERE IS STILL UNCERTAINTY IN WHETHER HIGH WINDS WILL MATERIALIZE
OVER SOME PARTS OF THE N INTERIOR. AND AT SOME POINT THE W FLOW
THROUGH THE STRAIT WILL LIKELY BLOCK THE S WINDS COMING UP THROUGH
PUGET SOUND...ALLOWING THEM TO DECREASE A LITTLE. 1525Z ACARS
SOUNDING FROM KSEA SHOWS 40-45KT SW WINDS AT 2000 FEET AND A
FREEZING LEVEL OF ABOUT 5900 FEET. THE S WINDS THROUGH PUGET SOUND
HAVE ALREADY BEGUN MIXING DOWN TO THE SURFACE FOR GUSTS TO 45 KT.
PAINE FIELD AND THE EVERGREEN POINT BRIDGE ARE ALREADY CLOSE TO THAT
RANGE.
STRONG NW FLOW ALOFT WILL DEVELOP THIS AFTERNOON BEHIND THE UPPER
LEVEL TROUGH AND CONTINUE THROUGH THIS EVENING. WITH SNOW LEVELS
FALLING QUICKLY TO BELOW PASS LEVELS THIS AFTERNOON...SNOW WILL
BEGIN PILING UP OVER THE CASCADES. THE DURATION OF THE STRONG NW
FLOW SHOULD BE SHORT ENOUGH TO LIMIT ACCUMULATIONS TO THE ADVISORY
RANGE...LESS THAN A FOOT...BUT THE VOLCANOES MAY COME CLOSE. A SNOW
ADVISORY REMAINS IN EFFECT FOR THE CASCADES THROUGH TONIGHT.
WITH THE FRONT ALREADY E OF THE AREA THIS MORNING PRECIP OVER THE
LOWLANDS HAS ALREADY BECOME MORE LOCALIZED AND SHOWERY. THIS WILL
REMAIN THE CASE THIS AFTERNOON AND TONIGHT.
DRIER NW FLOW ALOFT IS STILL EXPECTED SUNDAY THROUGH THE FIRST PART
OF MONDAY. MODELS ARE PRETTY DRY OVER THE LOWLANDS BUT MOS GUIDANCE
STILL HANGS ON TO CHANCE POPS FOR SHOWERS. CANNOT RULE OUT A ROGUE
SHOWER BUT IT WILL BE MAINLY DRY.
THE LATEST GFS AND NAM SHOW PRECIP FROM AN APPROACHING WEAK OCCLUDED
FRONT WORKING INLAND LATE IN THE AFTERNOON AND EVENING...WHICH IS A
LITTLE FASTER THAN PREVIOUS MODEL RUNS. KAM
.LONG TERM...PREVIOUS DISCUSSION FROM THE 245 AM AFD...A WEAKENING
WARM FRONTAL SYSTEM WILL MOVE THROUGH THE AREA MONDAY NIGHT AND
TUESDAY...BRINGING A LITTLE RAIN. A STRONGER SYSTEM WILL REACH THE
AREA WEDNESDAY OR THURSDAY WITH THE ECMWF 6-12 HOURS SLOWER THAN THE
GEM AND GFS. DRIER NORTHWESTERLY FLOW ALOFT WILL PREVAIL ON FRIDAY.
SCHNEIDER
&&
.HYDROLOGY...FLOODING IS UNLIKELY WITH THIS STORM. THE SYSTEM IS
FAST MOVING AND MOST PRECIPITATION IN THE MOUNTAINS WILL BE IN THE
FORM OF SNOW...WITH THE SNOW LEVEL FALLING TO 2500 FEET BY SUNDAY
MORNING. MORE SYSTEMS ARRIVE LATER NEXT WEEK BUT NONE LOOK WET
ENOUGH TO CAUSE ANY FLOODING. SCHNEIDER
&&
.AVIATION...A 994 MB LOW PRES CENTER WILL CROSS WESTERN WA TODAY
WITH STRONG WEST TO SW WIND ACROSS THE AREA. SURFACE WINDS OF 30 TO
40 KT WILL BE COMMON...WITH GUSTS TO 50-60 KT POSSIBLE. THE WIND
ALOFT IS WEST TO NORTHWEST. CIGS ARE MAINLY MVFR TO LOW-END VFR WITH
SHOWERS. WINDS WILL EASE THIS EVENING AS THIS SURFACE LOW EXITS
EAST...WITH SHOWERS MAINLY AFFECTING THE CASCADES.
KSEA...STRONG S/SW WINDS OF 25-40 KT THROUGH THIS EVENING. WILL SEE
SCATTERED SHOWERS IN THE REGION WHICH MAY LOWER CIGS INTO MVFR
RANGE. WINDS WILL EASE THIS EVENING. 33
&&
.MARINE...A 994 MB LOW IS OVER THE NORTH COAST NEAR LA PUSH AND WILL
SHIFT EAST TOWARD KBLI THIS AFTERNOON...THEN WEAKEN AS IT MOVES INTO
SOUTHERN B.C. THIS EVENING. STRONG ONSHORE FLOW IS DEVELOPING BEHIND
THIS SYSTEM WITH STORM FORCE WINDS OVER THE COASTAL WATERS AND THE
STRAIT OF JUAN DE FUCA. ELSEWHERE...GALES ARE FORECAST. WINDS WILL
EASE THIS EVENING AS THIS SYSTEM EXITS ALTHOUGH WILL STILL LIKELY
SEE GALES IN THE STRAIT.
A HIGH SURF ADVISORY IS IN EFFECT FOR THE NORTH AND CENTRAL COAST.
COMBINED SEAS OF 20-24 FT WILL AFFECT THE COAST STARTING THIS
MORNING AND SEAS WILL GRADUALLY SUBSIDE TONIGHT.
IT LOOKS LIKE LOW PRESSURE CROSSING WESTERN WASHINGTON TODAY WILL
NOT COINCIDE WITH HIGH TIDE. HOWEVER...HIGH WIND WAVES FROM STRONG
WINDS WILL CONTRIBUTE TO HIGHER TIDAL ANOMALIES. COASTAL FLOODING
STILL LOOKS UNLIKELY...BUT WE WILL CONTINUE TO WATCH IT THROUGH THE
DAY. 33
