AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PDT SAT AUG 29 2015

.SYNOPSIS...A FRONT WILL BRING RAIN AT TIMES TO WESTERN WASHINGTON 
TONIGHT BEFORE CHANGING TO SHOWERS. ADDITIONAL WEAKER FRONTS WILL 
REACH THE AREA THROUGH THE MIDDLE OF NEXT WEEK AS A LARGE TROUGH 
TAKES UP RESIDENCE OVER THE REGION. HIGH PRESSURE MAY BUILD OVER 
THE AREA NEXT WEEKEND.

&&

.SHORT TERM...WINDS CONTINUE TO EASE THIS EVENING WITH JUST BREEZY 
SW WINDS EXPECTED THE REST OF TONIGHT. A FRONTAL BAND FEATURE IS 
BRINGING RENEWED RAINFALL TO WRN WA AS IT PUSHES VERY SLOWLY 
INLAND. THIS FEATURE HAS PRODUCED LOCALLY HEAVY RAIN WITH NEARLY A 
HALF INCH OF RAIN REPORTED AT SHELTON FROM 7-8 PM. RADAR SHOWS 
STEADY RAIN INCREASING ALONG THE I-5 CORRIDOR WHICH MAY BE HEAVY AT 
TIMES INTO THE EARLY MORNING HOURS. THE FORECAST WAS UPDATED TO 
INCREASE RAINFALL COVERAGE...POPS...AND AMOUNTS FOR THE REST OF 
TONIGHT. 

THE TROUGH AXIS WILL SHIFT OVER WRN WA ON SUNDAY WITH A TRANSITION 
OVER TO SHOWERS DURING THE MORNING. SW FLOW ALOFT WILL PROBABLY RAIN
SHADOW MUCH OF GREATER PUGET SOUND WITH ONLY LIGHT RAIN AMOUNTS 
EXPECTED. HIGHS WILL REMAIN A LITTLE BELOW AVERAGE...STRUGGLING TO 
REACH OUT OF THE UPPER 60S EVEN WITH PARTIAL SUNSHINE.

THE LARGE SCALE UPPER LOW REMAIN OVER PUGET SOUND INTO EARLY NEXT 
WEEK. ANOTHER FRONTAL SYSTEM SHOULD BRING MORE RAIN INTO WRN WA 
SUNDAY NIGHT AND MONDAY. HIGHS WILL REMAIN COOL IN THE UPPER 60S. 
MERCER

.LONG TERM...FROM PREVIOUS DISCUSSION...SHORTWAVES WILL CONTINUE TO 
ROTATE THROUGH THE AREA IN THE MEAN UPPER LEVEL TROUGH THROUGH 
FRIDAY WITH A GOOD CHANCE OF SHOWERS. THE COOLEST AIR ALOFT WORKS 
OVER THE AREA BY ABOUT WED NIGHT WHEN THE SNOW LEVEL MIGHT BE AROUND 
5000FT IN THE NORTH CASCADES. A RIDGE AND WARMER AIR WILL LIKELY 
BUILD OVER THE AREA FOR NEXT WEEKEND.

&&

.AVIATION...FRONTAL SYSTEM OVER THE AREA TONIGHT WILL SHIFT EAST 
OF THE AREA AFTER MIDNIGHT. NARROW BAND OF HEAVY RAIN EMBEDDED IN 
THE FRONT WITH CEILINGS 1500-2500 FEET AND VISIBILITIES 2-4SM. THIS 
BAND OF HEAVIER PRECIPITATION WILL BE EAST OF THE AREA BY 07Z. 
BEHIND THE FRONT WEAK LOW LEVEL ONSHORE FLOW WITH SCATTERED SHOWERS. 
MULTIPLE CLOUD LAYERS FROM 2500 FEET TO 8000 FEET WITH CEILINGS 
MOSTLY IN THE 4000-5000 FOOT RANGE THROUGH SUNDAY. 

KSEA...BAND OF HEAVY RAIN WILL MOVE EAST OF THE TERMINAL BY 07Z. 
UNTIL THEN VISIBILITIES AS LOW AS 2 SM. BRIEF CEILINGS NEAR 1000 
FEET. CEILINGS FOR THE MOST PART IN THE 1500-2500 FOOT RANGE. 
CEILINGS LIFTING BACK UP TO NEAR 4000 FEET AFTER MIDNIGHT. LITTLE 
CHANGE THROUGHOUT THE DAY ON SUNDAY. BRIEF WESTERLY WINDS 8 TO 12 
KNOTS WILL SHIFT BACK TO SOUTHWEST 07Z-09Z AND REMAIN SOUTH 
SOUTHWESTERLY THROUGH SUNDAY. FELTON
&&

.MARINE...THE STRONG SURFACE LOW THAT MOVED NORTH THROUGH THE 
COASTAL WATERS OF WASHINGTON THIS AFTERNOON HAS WELL NORTH OF 
THE AREA. WINDS WILL CONTINUE TO EASE OVERNIGHT INTO SUNDAY MORNING. 
SMALL CRAFT ADVISORY WINDS OVER THE COAST...ADMIRALTY INLET AND 
NORTHERN INLAND WATERS WILL DROP BELOW SMALL CRAFT ADVISORY AFTER 
MIDNIGHT. 
 
AN ADDITIONAL SET OF WEAKER SYSTEMS WILL MOVE THROUGH THE WATERS 
MONDAY AND TUESDAY STRENGTHENING SOUTHWESTERLY AND SOUTHERLY WINDS 
MAINLY FOR THE COASTAL WATERS BUT ALSO SOME OF THE INTERIOR WATERS. 
 
&&

.SEW WATCHES/WARNINGS/ADVISORIES... 

WA...NONE. 

PZ...SMALL CRAFT ADVISORY UNTIL MIDNIGHT COAST...ADMIRALTY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
900 PM PDT SAT AUG 29 2015


.SYNOPSIS...A BAND OF RAIN OVER SOUTHWEST WASHINGTON AND NORTHWEST
OREGON WILL GRADUALLY SHIFT SOUTHEASTWARD ACROSS THE AREA TONIGHT AND
EARLY SUNDAY. EXPECT A MIX OF SUNSHINE AND AN OCCASIONAL SHOWER ON
SUNDAY. ANOTHER FRONT WILL STALL OVER WASHINGTON AND BRING A THREAT
FOR ADDITIONAL SHOWERS TO MAINLY OUR FAR NORTHERN ZONES MONDAY. THE
SHOWERY WEATHER SHOULD THEN SPREAD SOUTHWARD MIDWEEK AND MAINTAIN
NEAR AVERAGE TO SLIGHTLY BELOW AVERAGE TEMPERATURES. 


&&


.EVENING UPDATE...WATER VAPOR SATELLITE IMAGERY REVEALS A HIGHLY
AMPLIFIED PATTERN ACROSS THE PACIFIC OCEAN WITH A MEAN LONGWAVE
TROUGH CENTERED OVER THE WEST COAST. THE NEXT SHORTWAVE TROUGH IS
PUSHING SOUTHEASTWARD OUT OF THE GULF OF ALASKA AND CURRENTLY RESIDES
NEAR 130W OFF THE WASHINGTON COAST. A LOW LEVEL FRONT AHEAD OF THIS
SYSTEM IS CURRENTLY PUSHING ONTO THE OREGON COAST WITH FRONTAL
PASSAGE OCCURRING EARLIER THIS EVENING AT ASTORIA AND TILLAMOOK. THIS
FEATURE WILL BE THE PRIMARY FOCUS FOR PRECIPITATION OVERNIGHT AS IT
SLOWLY DROPS SOUTHEASTWARD ACROSS THE AREA...GENERALLY BRINGING
ANOTHER QUARTER TO THREE QUARTERS OF AN INCH OF RAIN...LOCALLY MORE
IN THE HIGHER TERRAIN AND ALONG THE COAST. LESSER AMOUNTS ARE MOST
LIKELY TOWARDS EASTERN LANE AND LINN COUNTIES WHERE THE FRONT WILL
STRUGGLE TO REACH BEFORE FALLING APART SUNDAY MORNING. 

SURFACE OBSERVATIONS INDICATE 35 TO 45 MPH GUSTS CONTINUE ALONG THE
BEACHES AND HEADLANDS OF THE CENTRAL OREGON COAST AHEAD OF THE
AFOREMENTIONED FRONT. THESE WINDS WILL EASE CONSIDERABLY UPON FRONTAL
PASSAGE...WHICH SHOULD OCCUR BETWEEN 10 PM AND MIDNIGHT.
ELSEWHERE...WINDS SHOULD HOLD RELATIVELY STEADY OVERNIGHT...PERHAPS
BRIEFLY INCREASING RIGHT AHEAD OF FRONTAL PASSAGE IN THE WILLAMETTE
VALLEY...BUT OVERALL WIND GUSTS SHOULD STAY WELL BELOW 30 MPH GOING
FORWARD TONIGHT AND SUNDAY.  

AN EXAMINATION OF INFRARED SATELLITE IMAGERY REVEALS PLENTY OF COLD
AIR CUMULUS WITH CLOUD TOPS REACHING -35C CURRENTLY NEAR 130W. THE
DEEPEST CONVECTION IS TIED TO THE -21C TO -23C 500MB ISOTHERMS. WHILE
THE COLDEST 500MB AIR WILL MOVE NORTH OF OUR CWA LATE TONIGHT AND
SUNDAY MORNING...IT APPEARS WE WILL BE CLIPPED BY ENOUGH -21C TO -22C
500MB TEMPERATURES ALOFT TO AT LEAST MENTION THUNDER AS A POSSIBILITY
NORTH OF A LINE EXTENDING BETWEEN SEASIDE AND SCAPPOOSE SUNDAY
MORNING. A LOWERING SUBSIDENCE INVERSION ON SUNDAY AFTERNOON SHOULD
LIMIT THE DEPTH OF INSTABILITY AND GRADUALLY RESULT IN DECREASING
SHOWER COVERAGE AND INTENSITY LATE SUNDAY AFTERNOON AND EVENING
ACROSS THE AREA. 

ANOTHER SHORTWAVE TROUGH CURRENTLY RESIDING OVER THE ALEUTIAN ISLANDS
WILL PUSH INTO WESTERN BRITISH COLUMBIA MONDAY AND PUSH ANOTHER FRONT
INTO THE PACIFIC NORTHWEST. GIVEN THE UPPER LEVEL DYANMICS WITH THIS
SYSTEM STAY IN BRITISH COLUMBIA...THIS SYSTEM WILL QUICKLY LOSE STEAM
AND STALL OVER NORTHWESTERN WASHINGTON ON MONDAY. NONETHELESS...IT
WILL LIKELY BRING A FEW SHOWERS AND CERTAINLY MORE CLOUD COVER ACROSS
OUR FAR NORTHERN ZONES ON MONDAY.  

MODELS GENERALLY AGREE A THIRD SHORTWAVE TROUGH CURRENTLY OVER VERY
NORTHERN ALASKA AND THE ARCTIC OCEAN WILL SLIDE SOUTHWARD AND PUSH
INTO THE PACIFIC NORTHWEST MIDWEEK. THIS SHOULD BRING ANOTHER GOOD
THREAT OF SHOWERS AND KEEP TEMPERATURES BELOW SEASONAL THROUGH AT
LEAST MIDWEEK. /NEUMAN

 
.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...PREVIOUS DISCUSSION
BELOW...AN UPPER TROUGH WILL REMAIN ALONG THE PACIFIC NORTHWEST COAST
THROUGH MUCH OF THE EXTENDED PERIOD. THE MODELS SHOW ANOTHER DECENT
PIECE OF ENERGY SWINGING THROUGH AROUND WEDNESDAY OR THURSDAY FOR A
BETTER CHANCE OF SHOWERS...BUT THE TIMING VARIES A BIT. THE MODELS
ARE INDICATING IT MAY DRY OUT AND START TO WARM UP SOME NEXT WEEKEND.
TOLLESON


&&


.AVIATION...A WEAK FRONT MOVING ONSHORE CURRENTLY BRINGING
PERIODS OF REDUCED CIGS AND VSBY TO THE COAST UNDER MODERATE TO 
HEAVY RAIN BANDS. EXPECT CIGS TO LOWER TOWARDS MVFR OVERNIGHT AND
PERSIST THROUGH SUNDAY MORNING. WILL ALSO CONTINUE TO SEE PERIODS
OF GUSTY SOUTHERLY WINDS THROUGH LATE TONIGHT. COASTAL CONDITIONS
LOOK TO IMPROVE TOWARDS VFR BY SUNDAY AFTERNOON.

CONDITIONS CURRENTLY VFR ACROSS THE INTERIOR. MAY SEE BRIEF
PERIODS OF REDUCED CIGS AND VSBY AT INTERIOR TAF SITES UNDER
HEAVIER RAIN BANDS...BUT CONDITIONS LOOK TO REMAIN GENERALLY VFR
THE NEXT 24 HOURS.

WILL ALSO SEE A SLIGHT CHANCE OF THUNDERSTORMS AS THE FRONT MOVES
ACROSS THE AREA. HOWEVER...CONFIDENCE REMAINS TOO LOW TO INCLUDE
IN THE UPCOMING TAF PACKAGE.


KPDX AND APPROACHES...CONDITIONS GENERALLY VFR THE NEXT 24 HOURS.
HOWEVER...BRIEF PERIODS OF REDUCED CIGS AND VSBY POSSIBLE UNDER
HEAVIER RAIN BANDS AS THE FRONT MOVES ACROSS THE AREA. WILL ALSO
SEE A SLIGHT CHANCE OF THUNDERSTORMS WITH THE FRONT. /64


&&


.MARINE...THE LOW PRESSURE SYSTEM THAT BROUGHT STORM AND GALE
FORCE WINDS TO OUR WATERS TODAY HAS MOVED NORTH OF OUR AREA
ALLOWING WINDS TO SUBSIDE THIS EVENING. A WEAK FRONT WILL MOVE
ACROSS THE WATERS TONIGHT AND COULD BRING A CHANCE FOR ISOLATED
THUNDERSTORMS. SOUTHWESTERLY WINDS WILL CONTINUE TO GUST TO AROUND
25 KT SO WILL LET THE GALE WARNING EXPIRE AND ISSUE A SMALL CRAFT
ADVISORY FOR WINDS FOR THE INNER WATERS THROUGH TONIGHT...AND THE
OUTER WATERS THROUGH SUNDAY MORNING. WINDS EASE FURTHER SUNDAY
AFTERNOON...BUT WILL FLIRT WITH ADVISORY CRITERIA THROUGH MUCH OF
NEXT WEEK DUE TO AN UNSETTLED WEATHER PATTERN.

SEAS ARE CURRENTLY AROUND 11 TO 13 FT SO HAVE ALSO ISSUED A SMALL
CRAFT ADVISORY FOR HAZARDOUS SEAS THROUGH TONIGHT. SEAS FALL TO
AROUND 8 TO 9 FT LATE TONIGHT AND REMAIN IN THIS RANGE THROUGH
MUCH OF NEXT WEEK DUE TO A SWELL BEING GENERATED IN THE GULF OF
ALASKA. /64

UPDATED THE AVIATION DISCUSSION

.UPDATE...A FEW SHOWERS WERE LINGERING OVER THE FAR EASTERN ZONES 
WHILE A STORM SYSTEM WAS MOVING INTO THE PACNW AND SPREADING SHOWERS 
TO THE WA/OR CASCADES. AS THE STORM SYSTEM MOVES INLAND THE SHOWERS 
WILL SPREAD EAST INTO THE REMAINDER OF THE AREA LATER TONIGHT AND 
INCREASE IN COVERAGE AND INTENSITY. THEREFORE THE ZONES WERE UPDATED 
TO SPREAD THESE SHOWERS FURTHER EAST INTO PORTIONS OF THE BASIN 
OVERNIGHT. OTHERWISE THE WINDS HAD DECREASED ACROSS THE 
REGION AND THE WIND/DUST STORM ADVISORIES WERE ALLOWED TO EXPIRE 
ALONG WITH THE RED FLAG WARNING. ALSO MINOR UPDATES WERE COMPLETED 
TO THE SKY CONDITIONS AND THE PRESENT SHORT TERM FORECAST APPEARS ON 
TRACK FOR NOW.

&&

.AVIATION...VFR CONDITIONS WILL PERSIST AT ALL TAF SITES UNTIL 08Z 
WHEN A STORM SYSTEM ENTERS THE PACIFIC NORTHWEST AND SPREADS CLOUDS 
AND SHOWERS CREATING AREAS OF MVFR CONDITIONS AT ALL TAF SITES 
BEGINNING WITH KDLS AND KYKM. AROUND 10Z AREAS OF MVFR CONDITIONS 
SHOULD BEGIN AROUND TAF SITES KPSC...KPDT...KALW...KRDM...AND BDN 
ESPECIALLY IN RAIN SHOWERS. AFTER 02Z THE CONDITIONS SHOULD SLOWLY 
IMPROVE TOWARD VFR CONDITIONS FROM WEST TO EAST. 

&&

.PREV DISCUSSION... /ISSUED 250 PM PDT SAT AUG 29 2015/ 

SHORT TERM...TONIGHT THROUGH MONDAY NIGHT...BREEZY TO LOW END WINDY 
CONDITIONS CONTINUE ACROSS THE REGION. ALSO AREAS OF BLOWING DUST 
MIXED WITH SMOKE CONTINUE TO REDUCE VISIBILITIES AT A FEW LOCATIONS 
IN THE BASIN. THUS WILL ALLOW THE CURRENT WIND AND BLOWING DUST 
ADVISORIES TO RUN UNTIL 6 PM. WILL CONTINUE TO SEE A FEW SHOWERS 
OVER THE CASCADE EAST SLOPES, ESPECIALLY IN WASHINGTON, AND OVER 
SOME OF OUR EASTERN ZONES INTO THE EVENING. STILL MAY BE ENOUGH 
INSTABILITY FOR A STRAY THUNDERSTORM OVER WALLOWA COUNTY UNTIL 
SUNSET. ANOTHER SYSTEM WILL MOVE ACROSS THE PACIFIC NORTHWEST 
SUNDAY. THIS SYSTEM IS LOOKING TO BE A DECENT PRECIP PRODUCER AND 
HAVE GONE WITH A WIDE SWATH OF 60-70 PERCENT POPS OVER THE AREA 
SUNDAY, PRIMARILY DURING THE MORNING. WINDS WILL CONTINUE TO BE 
BREEZY TO LOCALLY WINDY, THOUGH PRECIP SHOULD SIGNIFICANTLY REDUCE 
CHANCES OF BLOWING DUST. THERE IS SOME INDICATION OF ENOUGH 
INSTABILITY FOR STRAY THUNDERSTORMS OVER THE BLUE MOUNTAINS AND 
WALLOWA COUNTY. AT THIS TIME WILL LEAVE OUT THE MENTION OF 
THUNDERSTORMS AND WILL REEVALUTE THE POTENTIAL SUNDAY MORNING. FOR 
SUNDAY NIGHT THROUGH MONDAY NIGHT, WILL SEE A BROAD UPPER LEVEL 
TROUGH OVER THE REGION. THIS WILL KEEP A WEST-SOUTHWEST UPPER LEVEL 
FLOW OVER THE REGION. MOISTURE WITHIN THIS FLOW WILL KEEP A FEW 
SHOWERS GOING AT TIMES OVER THE WASHINGTON CASCADE EAST SLOPES. 
OTHERWISE CONDITIONS LOOK TO DRY, COOL AND LOCALLY BREEZY. 90 

LONG TERM...TUESDAY THROUGH SATURDAY...MODELS IN GOOD AGREEMENT IN 
KEEPING AN UNSETTLED WEATHER PATTERN OVER THE PACIFIC NORTHWEST 
THROUGH THE PERIOD. AT THIS TIME...IT APPEARS THE BEST CHANCE OF 
RAIN WILL BE WEDNESDAY/WEDNESDAY NIGHT AS AN UPPER LEVEL TROUGH 
MOVES THROUGH THE AREA. NORTHWEST FLOW IS EXPECTED TO SLOWLY DEVELOP 
BEHIND THE SYSTEM WITH CONDITIONS DRYING OUT MOST LOCATIONS...EXCEPT 
THE EAST SLOPES OF THE CASCADES AND THE NORTHEAST MOUNTAINS OF 
OREGON...SATURDAY. TEMPERATURES WILL REMAIN AT OR BELOW NORMAL 
THROUGH THE PERIOD.  EARLE

Area Forecast Discussion
National Weather Service Spokane WA
1032 PM PDT SAT AUG 29 2015

.SYNOPSIS...
Look for the wind to decrease early this evening as our fast
moving cold front moves out of the Inland Northwest. A vigorous
upper level disturbance will bring the Inland Northwest some much
needed rain on Sunday. Area wildfires will have a good chance of a
tenth to a quarter inch of rain. A cool and moist weather pattern
is expected much of next week.


&&

.DISCUSSION...
Evening update to allow the remaining Red Flag Warnings and Wind
Advisories to expire as winds diminish and relative humidity is
recovering. South to southwest winds will remain breezy across
the area with occasional gusts of 25 to 35 mph possible this
evening but advisory criteria winds are no longer expected.
Visibility has also improved across the region as gusty winds
diminish and will no longer loft the dust into the air. Most of
the showers that followed the frontal passage have moved off into
Montana this evening, but another batch of precipitation is
affecting western WA and the Cascade crest. This is associated
with the upper trough that will pivot across the region later
tonight and Sunday. More showers will be on the way overnight
along with a slight chance of thunderstorms under the cold pool
aloft. These showers should bring a better chance of wetting rains
to area wildfires. Areas of smoke will pool in some of the
valleys tonight as the inversion sets up but any showers will help
to limit this. /Kelch

&&

.AVIATION... 
06Z TAFS: A narrow band of showers and isolated thunderstorms
will track in the vicinity of KLWS through 08Z. A more substantial 
area of showers will continue to slowly push east of the Cascade
crest tonight, moving across eastern WA and north ID overnight and
Sunday as an upper level trough pivots across the region over the
next 24 hours. Winds have diminished this evening but will
increase and start to become gusty again after 15Z Sunday morning.
All TAF sites will likely be affected by -SHRA at some point with
the most likely time period between 14Z- 20Z with the passage of
the cold pool aloft. Confidence is low that any TAF site will see
thunderstorms but the more favorable site is KCOE after 18Z
Sunday. Smoke may again affect the region if area wildfires flare
up again but confidence remains low on timing and location of
smoke plumes. Gusty afternoon winds will diminish after sunset
Sunday. /EK
