AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND
857 AM PDT SUN MAR 29 2015

.SYNOPSIS...MILD AND MOSTLY DRY WEATHER THROUGH MON AS A FLAT UPPER
LEVEL RIDGE REMAINS OVER THE PAC NW. A COLD FRONT WILL PUSH ACROSS
THE REGION LATE MONDAY USHERING IN A MUCH COOLER AND MORE SEASONABLE
AIR MASS ALONG WITH SHOWERS AND LOWER SNOW LEVELS THAT WILL LAST
THROUGH THE END OF THE WORKWEEK.

&&

.SHORT TERM...WATER VAPOR PICTURES AND UPPER AIR PLOTS SHOWED THE
REGION UNDER A FLAT UPPER RIDGE WITH W FLOW ALOFT. A BAROCLINIC ZONE
TO THE N BROUGHT SOME LIGHT RAIN AS FAR S AS THE OLYMPIC PENINSULA
THIS MORNING. AN EXPECTED WSW FLOW ALOFT TODAY IS NOT LIKELY TO
ALLOW THE BAROCLINIC ZONE TO SPREAD S TODAY...ALTHOUGH VISIBLE
PICTURES DID SHOW SOME LAYERED CLOUDS OFF THE S WA AND FAR N OREGN
COAST THIS MORNING, AS SUCH WILL LEAVE IN A SLIGHT CHANCE FOR SOME
SHOWERS OVER THE SW CORNER OF WA TODAY...WITH THE REST OF THE AREA
EXPECTED TO REMAIN DRY AND MILD TODAY...AND THROUGH MOST OF THE DAY
MON.

AN UPPER LEVEL TROUGH WILL DIVE DOWN FROM THE GULF OF ALASKA ON
MON...FINALLY DRIVING A STALLED FRONTAL BOUNDARY OFF VANCOUVER
ISLAND ONSHORE AS A COLD FRONT. EXPECT RAIN TO PUSH ONTO THE COAST
MON EVENING...THEN INLAND OVERNIGHT ALTHOUGH MODELS CONTINUE TO
TREND SLIGHTLY LATER WITH TIMING OF THE FRONT. THE UPPER LEVEL
TROUGH WILL MOVE THROUGH ON TUE...USHERING IN A SIGNIFICANTLY COOLER
AIR MASS. THE FCST MODELS ARE INDICATING THAT THERE WILL BE PLENTY
OF POSTFRONTAL SHOWERS ACROSS THE REGION ON TUE. FORECAST MODEL
SOUNDINGS SHOW SOME INSTABILITY AND FORCING WITH THE FRONT MONDAY
NIGHT AND A BIT INTO TUESDAY MORNING...BUT IT LOOKS LIKE THERE MAY
BE TOO MUCH OF A CAP TO REALLY PRODUCE ANY THUNDER SO HAVE LEFT IT
OUT FOR NOW. HOWEVER IT MAY BE ONE OF THOSE DAYS WITH PERIODIC HEAVY
SHOWERS...SOME CONTAINING SMALL HAIL. THE COLDER AIR SHOULD ALSO
DROP SNOW LEVELS DOWN TO CASCADE PASSES WHERE SEVERAL INCHES OF
ACCUMULATING SNOW MAY FALL. BOWEN/PYLE

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS. TUESDAY NIGHT
THROUGH FRIDAY...A PROGRESSIVE PATTERN IS EXPECTED FOR THE EXTENDED
FCST PERIOD. BEHIND THE UPPER LEVEL TROUGH ON TUE...FCST CONFIDENCE
IS FAIRLY HIGH THAT ANOTHER SHORTWAVE WILL MOVE ONSHORE
WED...BRINGING CONTINUED SHOWERS AND MOUNTAIN SNOW INTO THU MORNING.
THERE IS THEN A SHORTWAVE UPPER LEVEL RIDGE THAT IS MODELED TO MOVE
INTO THE REGION ON THU. THIS MAY END UP PROVIDING A BRIEF BREAK FROM
THE SHOWER ACTIVITY LATER THU INTO FRI BEFORE A DEEP UPPER TROUGH
MOVES TOWARD THE COAST ON FRI INTO NEXT WEEKEND. FCST CONFIDENCE
BECOMES LOWER TOWARD THE END OF THE WEEK. FRI COULD END UP BEING
MOSTLY DRY...BUT THE FCST MODELS SEEM TO BE TRENDING TOWARD SPEEDING
UP THE ARRIVAL OF THE DEEP TROUGH...WHICH WOULD BRING MORE RAIN
ONSHORE FRI. PYLE

300 PM PDT SAT MAR 28 2015

.SYNOPSIS...SHOWERS REMAIN IN THE HIGHER TERRAIN OF THE CASCADES AND
COAST RANGE BUY WILL CONTINUE TO TAPER OFF AND EVENTUALLY END LATER
THIS AFTERNOON AND EARLY EVENING. A MOIST FRONTAL BOUNDARY WILL SIT
NEARLY STATIONARY OVER BRITISH COLUMBIA AND NORTHERN WASHINGTON THIS
WEEKEND...LEAVING US TO ENJOY MILD AND MOSTLY DRY WEATHER THROUGH MON
AS FLAT UPPER LEVEL RIDGING REMAINS OVER THE PAC NW. THE FRONTAL
BOUNDARY WILL SWING THROUGH AS A COLD FRONT MON NIGHT INTO
TUE...BRINGING WIDESPREAD RAIN AND SNOW LEVELS LOWERING DOWN TO THE
CASCADE PASSES. A FAIRLY PROGRESSIVE PATTERN THEN APPEARS TO BE ON
TAP FOR THE REST OF NEXT WEEK. EXPECT PLENTY OF CLOUDS...PERIODIC
ROUNDS OF SHOWERS...AND COOLER TEMPERATURES. SNOW LEVELS SHOULD
REMAIN BELOW THE CASCADE PASSES FOR MUCH OF NEXT WEEK.

&&

.SHORT TERM...TONIGHT THROUGH TUESDAY...
LIGHT SHOWERS CONTINUE IN THE COOL POST FRONTAL AIR MASS THIS
AFTERNOON...MAINLY OVER THE S WASHINGTON AND FAR N OREGON CASCADES
AND COAST RANGE. BASED ON RADAR IMAGERY...THE SHOWERS ARE BECOMING
NOTICEABLY LESS NUMEROUS AND LOWER TOPPED OVER THE PAST FEW HOURS AS
THE ATMOSPHERE BEGINS TO STABILIZE. EXPECT SHOWERS TO END COMPLETELY
BY EARLY THIS EVENING. OTHERWISE...EXPECT PARTLY CLOUDY SKIES WITH
PLENTY OF CUMULUS CLOUDS AROUND AND ALSO HIGH CIRRUS STREAMING IN
AHEAD OF A WARM FRONT.

AN OFFSHORE FRONTAL SYSTEM WILL REMAIN NEARLY STATIONARY OVER THE
WEEKEND...FOCUSING AN ATMOSPHERIC RIVER OF SUBTROPICAL MOISTURE ON
VANCOUVER ISLAND AND FAR NW WASHINGTON. THIS WILL LEAVE US TO ENJOY
MILD AND MAINLY DRY CONDITIONS ON THE WARM SIDE OF THE FRONT TONIGHT
THROUGH MOST OF MON. THE FCST MODELS CONTINUE TO INDICATE THAT THERE
IS A SLIGHT CHANCE THAT LIGHT RAIN MAY CLIP THE S WASHINGTON AND FAR
N OREGON COAST AT TIMES DURING THIS PERIOD. THERE WILL BE SOME HIGH
CLOUDS STREAMING ACROSS THE REGION ON SUN AND MON...ESPECIALLY FOR
THE NW PORTIONS OF THE FCST AREA. ELSEWHERE...EXPECT THERE TO BE SOME
DECENT SUNSHINE. AFTERNOON HIGH TEMPS SHOULD CLIMB BACK INTO THE MID
TO UPPER 60S OVER THE INTERIOR LOWLANDS.

AN UPPER LEVEL TROUGH WILL DIVE DOWN FROM THE GULF OF ALASKA ON
MON...FINALLY DRIVING THE STALLED FRONTAL BOUNDARY ONSHORE AS A COLD
FRONT. EXPECT RAIN TO PUSH ONTO THE COAST MON EVENING...THEN INLAND
OVERNIGHT. THE UPPER LEVEL TROUGH WILL MOVE THROUGH ON TUE...USHERING
IN A SIGNIFICANTLY COOLER AIR MASS. THE FCST MODELS ARE INDICATING
THAT THERE WILL BE PLENTY OF POSTFRONTAL SHOWERS ACROSS THE REGION ON
TUE. THE FCST MODEL SOUNDINGS ARE ALSO LOOKING DECENTLY UNSTABLE...SO
MAY NEED TO LOOK AT ADDING THUNDER CHANCES TO THE FCST IN THE NEXT
DAY OR TWO. AT THE VERY LEAST...IT WILL PROBABLY BE ONE OF THOSE DAYS
WITH PERIODIC HEAVY SHOWERS...SOME LIKELY CONTAINING SMALL HAIL. THE
COLDER AIR SHOULD ALSO DROP SNOW LEVELS DOWN TO THE CASCADE
PASSES...WHERE SEVERAL INCHES OF ACCUMULATING SNOW MAY FALL. PYLE


.LONG TERM...TUESDAY NIGHT THROUGH FRIDAY...A PROGRESSIVE PATTERN IS
EXPECTED FOR THE EXTENDED FCST PERIOD. BEHIND THE UPPER LEVEL TROUGH
ON TUE...FCST CONFIDENCE IS FAIRLY HIGH THAT ANOTHER SHORTWAVE WILL
MOVE ONSHORE WED...BRINGING CONTINUED SHOWERS AND MOUNTAIN SNOW INTO
THU MORNING. THERE IS THEN A SHORTWAVE UPPER LEVEL RIDGE THAT IS
MODELED TO MOVE INTO THE REGION ON THU. THIS MAY END UP PROVIDING A
BRIEF BREAK FROM THE SHOWER ACTIVITY LATER THU INTO FRI BEFORE A
DEEP UPPER TROUGH MOVES TOWARD THE COAST ON FRI INTO NEXT WEEKEND.
FCST CONFIDENCE BECOMES LOWER TOWARD THE END OF THE WEEK. FRI COULD
END UP BEING MOSTLY DRY...BUT THE FCST MODELS SEEM TO BE TRENDING
TOWARD SPEEDING UP THE ARRIVAL OF THE DEEP TROUGH...WHICH WOULD
BRING MORE RAIN ONSHORE FRI. PYLE

&&

.AVIATION...JUST A FEW SHOWERS REMAINING THIS AFTERNOON OVER SW
WASHINGTON AND ALSO IN THE CASCADES. VFR CONDITIONS AT THE
TERMINALS THIS AFTERNOON WITH VFR CIGS AND SCT CUMULUS WITH BASES
AROUND 3000 FT. MAY OCCASIONALLY SEE SOME MVFR CIGS DEVELOP WITH
THESE...BUT OTHERWISE VFR CONTINUES THIS EVENING WITH INCREASING
HIGH CLOUDS SPREADING OVER THE AREA. DEWPOINTS A BIT LOWER TODAY
THAN YESTERDAY AND OFFSHORE LOW LEVEL FLOW WILL EASE INTO THE
OVERNIGHT PERIOD ALONG WITH AT LEAST A BKN HIGH CLOUD DECK
OVERHEAD. THUS...THIS SHOULD PRECLUDE MOST FOG DEVELOPMENT. ONE
EXCEPTION MAY BE DOWN TOWARDS KEUG WHERE HIGH CLOUDS MAY NOT BE
AS THICK/PREVALENT...THOUGH EVEN THEN IT MAY BE A STRUGGLE TO
COOL ENOUGH FOR FOG DEVELOPMENT.

KPDX AND APPROACHES...VFR CIGS CONTINUE THIS AFTERNOON...BUT
SHOULD DECREASE AND SCATTER THIS EVENING. INCREASING HIGH CLOUDS
OVERNIGHT AND THESE SHOULD PRECLUDE FOG DEVELOPMENT. SOUTHERLY
SURFACE WINDS AROUND 10 KT WILL DECREASE LATER THIS EVENING AND
BECOME LIGHT/VARIABLE LATE. CULLEN

&&

.MARINE...SURFACE PRESSURE GRADIENT CONTINUES TO INCREASE A BIT IN
BETWEEN BUILDING HIGH PRESSURE OVER THE WATERS AND A LOW PRESSURE
SYSTEM IN THE GULF OF ALASKA. AN ASCAT PASS AROUND NOON TODAY
INDICATED WINDS OVER THE NORTHERN OUTER WATERS AROUND 18 KT NEAR
THE BOUNDARY OF THE OUTER WATERS. AS THE GRADIENT INCREASES A BIT
FURTHER...WINDS WILL INCREASE AND EXPECT SMALL CRAFT ADVISORY
STRENGTH GUSTS. THEREFORE HAVE ISSUED AN ADVISORY FOR WINDS FOR
THE NORTHERN OUTER WATERS WITH THE AREA OF CONCERN N OF CANNON
BEACH AND GENERALLY BEYOND 20 NM OFFSHORE. GUSTS TO 25 KT THROUGH
THE OVERNIGHT HOURS AND INTO EARLY SUN MORNING CAN BE EXPECTED.
ELSEWHERE...WINDS GENERALLY AROUND 15 KT OR LESS.

SEAS WILL HOLD AROUND 8 TO 9 FT TONIGHT...BEFORE POSSIBLY
INCREASING TO 10 FT LATE SUNDAY AFTERNOON INTO MONDAY. SOMEWHAT
LOWER CONFIDENCE IN THE EXTENT OF TIMING OF 10 FT SEAS SO HOLDING
OFF ON ADVISORY FOR SEAS AT THIS POINT...BUT SUSPECT THAT IT WILL
BE NECESSARY FOR AT LEAST THE NORTHERN WATERS. WINDS BECOME
SOUTHERLY AND INCREASE SUNDAY NIGHT AND MONDAY AHEAD OF AN
APPROACHING FRONTAL SYSTEM THAT WILL CROSS THE WATERS MONDAY
NIGHT. A SMALL CRAFT ADVISORY FOR WINDS LIKELY NEEDED FOR THIS
TIME...AS WELL AS AN ADVISORY FOR HAZARDOUS SEAS ON MONDAY NIGHT

INCREASED CLOUD COVER COMPARED TO THEIR COUNTERPARTS FARTHER SOUTH.
IN ADDITION...THERE IS A SLIGHT CHANCE THAT THE FAR NORTHWEST ZONES
MAY GET CLIPPED BY A LIGHT RAIN SHOWER OR TWO DURING THIS PERIOD.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND
243 AM PDT SAT MAR 28 2015

.SYNOPSIS...SHOWERS WILL GRADUALLY DIMINISH THROUGH EARLY SATURDAY
BEHIND A COLD FRONT. DRY AND MILD WEATHER LOOKS TO RETURN LATE
SATURDAY THROUGH EARLY MONDAY. ANOTHER FRONT BRINGS MORE RAIN AND
COOLER WEATHER TO THE AREA BEGINNING LATE MONDAY AND CONTINUING
THROUGH NEXT WEEK. SNOW LEVELS WILL LIKELY DROP BELOW CASCADE PASS
LEVELS DURING THIS PERIOD.

&&

.SHORT TERM...SATURDAY THROUGH TUESDAY...WESTERLY FLOW IS ALREADY
BEGINNING TO CREATE A VALLEY SHADOW WITH SHOWERS TONIGHT WITH A COLD
FRONT HAVING PASSED THROUGH LATE FRIDAY EVENING. HOWEVER THIS FLOW
WILL CONTINUE TO FAVOR SHOWERS ON THE WINDWARD SIDES OF THE COAST
RANGE AND CASCADES DUE TO OROGRAPHIC ENHANCEMENT THROUGH THIS
MORNING. CONDITIONS SHOULD BE MOSTLY DRY BY NO LATER THAN THIS
AFTERNOON AS RELATIVELY FLAT RIDGING BUILDS INTO THE AREA...LASTING
THROUGH MONDAY MORNING WHEN THE NEXT FRONT APPROACHES. DESPITE A
RELATIVELY DRY WEEKEND FORECAST...AN ATMOSPHERIC RIVER AIMED AT
SOUTHWEST BRITISH COLUMBIA AND NORTHWEST WASHINGTON WILL REMAIN CLOSE
ENOUGH THAT OUR NORTHERN PORTIONS OF THE CWA WILL SEE INCREASED CLOUD
COVER COMPARED TO THEIR COUNTERPARTS FARTHER SOUTH. IN ADDITION...OUR
FAR NORTHWEST ZONES MAY GET CLIPPED BY A LIGHT RAIN SHOWER OR TWO
DURING THIS PERIOD.

MONDAY LOOKS LIKE THE WARMEST DAY THIS WEEK...BUT ONLY SLIGHTLY
WARMER THAN SUNDAY...WITH HIGHS IN THE MID TO UPPER 60S IN THE VALLEY
AND AROUND 60 ALONG THE COAST AND RANGING FROM ABOUT 5 TO 10 DEGREES
ABOVE NORMAL FOR THIS TIME OF YEAR. HOWEVER RAIN CHANCES INCREASE
AGAIN MONDAY AS THE NEXT FRONT COMES ASHORE. MODELS HAVE SLOWED THE
FRONT WITH RAIN CHANCES OVER LAND NOT REALLY INCREASING NOW UNTIL
AFTER 00Z TUESDAY AND LASTING THROUGH THE DAY TUESDAY. MODELS
CONTINUE TO BRING SNOW LEVELS DOWN BEHIND THE FRONT WITH A FEW INCHES
OF NOW POSSIBLE AT PASS LEVEL TUESDAY. BOWEN


.LONG TERM...TUESDAY NIGHT THROUGH FRIDAY...A RATHER ACTIVE WESTERLY
TO NORTHWESTERLY FLOW PATTERN LOOKS TO LINGER ACROSS THE AREA WITH
RAIN CHANCES EVERY DAY THROUGH THE WORKWEEK. MODELS ARE STILL
TRENDING TOWARD A BREAK IN THE ACTION TOWARDS NEXT THURSDAY SO HAVE
CONTINUED TO TREND POPS DOWNWARD THEN. MODELS DIVERGE FRIDAY WITH THE
ECMWF SHOWING A BUILDING RIDGE WHILE THE GFS SHOWS A FRONT
TRAVERSING THE AREA. HAVE FAVORED THE WETTER GFS SOLUTION BUT NUDGED
TOWARD CLIMO POP...ABOUT 40 PERCENT RIGHT NOW...DUE TO UNCERTAINTY.
BOWEN

&&

.AVIATION...THE COLD FRONT WHICH MOVED THROUGH HAS PROGRESSED OFF
TO THE EAST...LEAVING SCATTERED SHOWERS ACROSS THE AREA. UNSTABLE
AIRMASS BEHIND THE FRONT IS KEEPING INLAND SITES VFR THIS SHOULD
CONTINUE THROUGH THE DAY TODAY WITH SHOWERS CLEARING OUT OF THE
AREA LATER THIS MORNING. CONTINUED ONSHORE FLOW IS MAKING KAST
CIGS BOUNCE BETWEEN VFR AND MVFR. THE BULK OF THE MOISTURE IS
NORTH OF KONP...WHICH IS KEEPING THIS SITE PRIMARILY VFR. WITH
CONTINUED ONSHORE FLOW...CIGS AT KONP WILL PROBABLY DROP DOWN TO
MVFR OVER THE NEXT FEW HOURS. EXPECT CONDITIONS TO IMPROVE BY
SATURDAY AFTERNOON ALONG THE COAST...WITH VFR AND DRY CONDITIONS.

KPDX AND APPROACHES...VFR CONDITIONS THIS MORNING WILL CONTINUE
THROUGH THIS EVENING. SHOWERS CURRENTLY AROUND THE TERMINAL
SHOULD CLEAR OUT BY 17Z THIS MORNING. -MCCOY

&&

.MARINE...WESTERLY WINDS ARE WEAKENING ACROSS THE WATERS THIS
MORNING AS HIGH PRESSURE BUILDS OVER THE WATERS. SEAS CURRENTLY
HOVERING AROUND 9 TO 10 FT ARE EXPECTED TO FALL TO 7 TO 9 FT BY
MID-MORNING. HIGH PRES BUILDING OVER THE WATERS AND LOW PRES OVER
THE GULF OF ALASKA MAY TIGHTEN THE SW PRESSURE GRADIENT...WHICH
COULD INCREASE WINDS TO LOW-END SMALL CRAFT ADVISORY CRITERIA OVER
THE NORTHERN OUTER WATERS SAT NIGHT AND SUN. THE LOW PRES SYSTEM
OVER THE GULF OF ALASKA WILL ALSO BRING IN INCREASING WESTERLY
SWELL ON SUNDAY...WHICH IS EXPECTED TO BUILD SEAS TO 10 TO 12 FT
SUNDAY AFTERNOON THROUGH MONDAY.

ANOTHER FRONT IS EXPECTED TO MOVE THROUGH THE WATERS MONDAY
EVENING...WHICH WILL BRING ANOTHER ROUND OF SMALL CRAFT ADVISORY
WINDS TO THE WATERS. A MORE PROGRESSIVE PATTERN LOOKS TO BE IN
STORE THROUGH MIDWEEK NEXT WEEK. -MCCOY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND
854 AM PDT FRI MAR 27 2015

.SYNOPSIS...HIGH PRESSURE WILL LEAD TO ANOTHER DAY WITH ABOVE
AVERAGE TEMPERATURES AND SOME MORNING FOG IN THE LOWLANDS TODAY.
HOWEVER...A FRONT WILL SPREAD RAIN SHOWERS INTO THE AREA THIS EVENING
AND TONIGHT. SHOWERS SHOULD DIMINISH EARLY SATURDAY. DRY AND MILD
WEATHER LOOKS TO RETURN LATE SATURDAY THROUGH EARLY MONDAY. ANOTHER
FRONT BRINGS MORE RAIN AND COOLER WEATHER TO THE AREA BEGINNING LATE
MONDAY AND CONTINUES INTO THE MIDDLE OF NEXT WEEK. SNOW LEVELS WILL
LIKELY DROP BELOW CASCADE PASS LEVELS DURING THIS PERIOD.

&&

.UPDATE...SURFACE OBSERVATIONS AND FOG PRODUCT INDICATE FOG IS MUCH
LESS WIDESPREAD THAN YESTERDAY MORNING. NONETHELESS...THERE ARE SOME
PATCHES OF DENSE FOG ALONG THE INTERSTATE 5 CORRIDOR IN SOUTHWEST
WASHINGTON AND NORTHWEST OREGON. MCMINNVILLE...CORVALLIS AND PORTIONS
OF CLARK COUNTY HAVE SEEN THE MOST PERSISTENT VISIBILITIES OF A
QUARTER MILE OR LESS THIS MORNING. GIVEN THE PATCHY NATURE OF THE FOG
AND BASED ON THE FACT THAT IS MUCH SHALLOWER THAN YESTERDAY AND
THEREFORE SHOULD DISSIPATE MUCH FASTER...WILL HANDLE THE FOG WITH A
NOWCAST INSTEAD OF A DENSE FOG ADVISORY THIS MORNING.

MEANWHILE...SURFACE ANALYSIS AND SATELLITE IMAGERY INDICATE A
SOUTHWEST MARINE PUSH IS CURRENTLY UNDERWAY WITH LOW CLOUDS FIRMLY
ENTRENCHED ALONG THE ENTIRE OREGON COAST. IN FACT...MARINE CLOUDS ARE
KNOCKING ON THE DOORSTEP OF EUGENE. THE NAM HAS FINALLY PICKED UP ON
THIS IDEA AND SUGGESTS CLOUDS WILL LIKELY ENTER THE SOUTHERN
WILLAMETTE VALLEY BEFORE BURNING BACK INTO THE COAST RANGE LATER THIS
MORNING. THIS IDEA SEEMS PLAUSIBLE SO TRENDED THE SKY FORECAST TO
DEPICT THIS SCENARIO. HOWEVER...WOULD NOT BE SURPRISED TO SEE THESE
CLOUDS SPREAD UP THE ENTIRE WILLAMETTE VALLEY EITHER SO THERE IS A
DECENT AMOUNT OF UNCERTAINTY IN THIS PORTION OF THE FORECAST.
GIVEN THE LOW CLOUDS AND COOLER AIR INFILTRATING OUR SOUTHERN
ZONES...TEMPERATURES WERE NUDGED DOWNWARD IN THIS REGION...BUT IF
CLOUDS WERE TO SPREAD FARTHER NORTH...OUR TEMPERATURE FORECAST IS
LIKELY TOO HIGH FOR THE CENTRAL AND NORTHERN WILLAMETTE VALLEY...TOO.

A FRONT CURRENTLY NEAR 130W WILL WORK ITS WAY INTO NORTHWEST OREGON
AND SOUTHWEST WASHINGTON THIS EVENING. IT APPEARS THE FIRST RAIN
SHOWERS SHOULD ARRIVE ON THE COAST BETWEEN 4 PM AND 6 PM AND BETWEEN
6 PM AND 9 PM ACROSS THE WILLAMETTE VALLEY. QPF STILL LOOKS RATHER
LIGHT WITH THIS SYSTEM.

THE AREA LOOKS TO DRY OUT RELATIVELY QUICKLY SATURDAY
MORNING...EXCEPT ACROSS THE FAR NORTH WHERE A FEW SHOWERS MAY LINGER
THROUGH THE DAY.

RELATIVELY FLAT RIDGING LOOKS TO BRING DRY AND MILD WEATHER TO THE
AREA LATE SATURDAY THROUGH MONDAY. HOWEVER...AN ATMOSPHERIC RIVER
AIMED AT SOUTHWEST BRITISH COLUMBIA RIVER AND NORTHWEST WASHINGTON
WILL REMAIN CLOSE ENOUGH THAT OUR FAR NORTHWEST ZONES WILL CERTAINLY
SEE INCREASE CLOUD COVER COMPARED TO THEIR COUNTERPARTS FARTHER
SOUTH...AND PERHAPS A PERIOD OR TWO OF LIGHT RAIN DURING THIS PERIOD.
/NEUMAN



.LONG TERM (PREVIOUS DISCUSSION)...SUN NIGHT THROUGH THU...OVERALL
PATTERN REMAINS RATHER ZONAL...WITH WESTERLY FLOW ALOFT OVER THE
REGION. THIS MEANS FRONTS WILL PUSH ACROSS THE REGION FROM TIME TO
TIME...BUT NO SIGNIFICANTLY STRONG OR ORGANIZED SYSTEMS EXPECTED.
CLOUDS WILL INCREASE ON MON WITH ANOTHER ROUND OF RAIN FOR LATE IN
THE DAY AND MON NIGHT. LIKELY SEE SHOWERS CONTINUE ON TUE AND TUE
NIGHT AS COOLER AIR ALOFT PUSHES ACROSS REGION.
AFTERWARDS...CONFIDENCE IN ANY SOLUTION BEGINS TO DROP AS MODELS
DIVERGE ON ANY PARTICULAR SOLUTION. WILL TREND TOWARDS DRIER BUT KEEP
SOME MINOR THREAT OF SHOWERS WITH NEAR SEASONABLE TEMPERATURES FOR
SECOND HALF OF NEXT WEEK. ROCKEY.

&&

.AVIATION...POCKETS OF IFR FOG AND LOW STRATUS HAVE FORMED OVER
MUCH OF THE REGION THIS MORNING...ALTHOUGH COVERAGE IS NOT AS
EXTENSIVE AS WE SAW YESTERDAY MORNING. EXPECT THE FOG AND STRATUS
TO BURN OFF BETWEEN 16Z AND 18Z. BASED ON SATELLITE OBSERVATIONS
THIS MORNING...IT APPEARS THAT A SOUTHERLY STRATUS SURGE IS
UNDERWAY ALONG THE CENTRAL OR COAST AND THROUGH THE COAST RANGE
GAPS INTO THE WILLAMETTE VALLEY. ADDED AN IFR STRATUS DECK TO THE
KEUG TAF THIS MORNING. THE 12Z NAM AND RAP MODEL GUIDANCE SUGGEST
THE STRATUS MAY SURGE UP THE WILLAMETTE VALLEY THROUGH THE
DAY...LIKELY REACHING KSLE AND WITH AN OUTSIDE CHANCE OF IT GETTING
INTO THE NORTHERN WILLAMETTE VALLEY. CONFIDENCE IN THE FCST MODELS
IS NOT ALL THAT HIGH...SO WILL BE MONITORING SATELLITE TRENDS
CLOSELY.

RAIN AND MVFR CIGS WILL ACCOMPANY THE ARRIVAL OF A COLD FRONT
LATER TODAY AND TONIGHT. EXPECT THE FRONT TO BEGIN TO IMPACT THE
COAST LATE THIS AFTERNOON...AND MOVE INTO THE INTERIOR THIS
EVENING. SHOWERS AND MVFR CIGS MAY LINGER THROUGH MUCH OF SAT
MORNING.

KPDX AND APPROACHES...MAINLY VFR CONDITIONS EXPECTED THIS
MORNING...ALTHOUGH A BRIEF PERIOD OF IFR FOG IS POSSIBLE THROUGH
ABOUT 17Z. THERE IS A SLIGHT CHANCE THAT A SOUTHERLY STRATUS
SURGE WILL BRING IFR CIGS TO THE TERMINAL LATE THIS MORNING OR
THIS AFTERNOON. IF NOT...VFR SHOULD PERSIST INTO THE EVENING. A
COLD FRONT WILL BRING RAIN AND LIKELY MVFR CIGS LATER THIS EVENING
AND OVERNIGHT. PYLE

&&

.MARINE...BENIGN CONDITIONS PREVAIL THROUGH LATE THIS MORNING
WITH WINDS AROUND 10 KT AND SEAS AROUND 8 FT UNDER WEAK HIGH
PRESSURE. A COLD FRONT WILL PUSH TOWARD THE WATERS THIS AFTERNOON
ALLOWING WINDS TO INCREASE OUT OF THE SOUTH WITH GUSTS TO 25 KT
EXPECTED TO DEVELOP AHEAD OF THE FRONT. EXTENDED THE SMALL CRAFT
ADVISORY FOR WINDS OVER ALL OF THE WATERS THROUGH LATE TONIGHT.
SEAS MAY CLIMB TO AROUND 10 FT DURING THE PERIOD OF THE STRONGEST
WINDS.

WEAK HIGH PRES RETURNS TO THE WATERS OVER THE WEEKEND. ANOTHER
FRONT IS EXPECTED TO MOVE THROUGH ON MON. THIS FRONT LOOKS A
LITTLE MORE IMPRESSIVE AND SHOULD BRING A SOLID ROUND OF SMALL
CRAFT ADVISORY WINDS...WITH A SMALL CHANCE OF GALES. A MORE
PROGRESSIVE WEATHER PATTERN FOR THE FIRST HALF OF NEXT WEEK.
EXPECT SEAS TO REACH INTO THE LOW TEENS LATE SUN OR MON AND REMAIN
ABOVE 10 FT FOR THE NEXT SEVERAL DAYS. PYLE

WASHINGTON AND NORTHWEST OREGON. MCMINNVILLE...CORVALLIS AND PORTIONS
OF CLARK COUNTY HAVE SEEN THE MOST PERSISTENT VISIBILITIES OF A
QUARTER MILE OR LESS THIS MORNING. GIVEN THE PATCHY NATURE OF THE FOG
AND BASED ON THE FACT THAT IS MUCH SHALLOWER THAN YESTERDAY AND
THEREFORE SHOULD DISSIPATE MUCH FASTER...WILL HANDLE THE FOG WITH A
NOWCAST INSTEAD OF A DENSE FOG ADVISORY THIS MORNING.

MEANWHILE...SURFACE ANALYSIS AND SATELLITE IMAGERY INDICATE A
SOUTHWEST MARINE PUSH IS CURRENTLY UNDERWAY WITH LOW CLOUDS FIRMLY
ENTRENCHED ALONG THE ENTIRE OREGON COAST. IN FACT...MARINE CLOUDS ARE
KNOCKING ON THE DOORSTEP OF EUGENE. THE NAM HAS FINALLY PICKED UP ON
THIS IDEA AND SUGGESTS CLOUDS WILL LIKELY ENTER THE SOUTHERN
WILLAMETTE VALLEY BEFORE BURNING BACK INTO THE COAST RANGE LATER THIS
MORNING. THIS IDEA SEEMS PLAUSIBLE SO TRENDED THE SKY FORECAST TO
DEPICT THIS SCENARIO. HOWEVER...WOULD NOT BE SURPRISED TO SEE THESE
CLOUDS SPREAD UP THE ENTIRE WILLAMETTE VALLEY EITHER SO THERE IS A
DECENT AMOUNT OF UNCERTAINTY IN THIS PORTION OF THE FORECAST.
GIVEN THE LOW CLOUDS AND COOLER AIR INFILTRATING OUR SOUTHERN
ZONES...TEMPERATURES WERE NUDGED DOWNWARD IN THIS REGION...BUT IF
CLOUDS WERE TO SPREAD FARTHER NORTH...OUR TEMPERATURE FORECAST IS
LIKELY TOO HIGH FOR THE CENTRAL AND NORTHERN WILLAMETTE VALLEY...TOO.

A FRONT CURRENTLY NEAR 130W WILL WORK ITS WAY INTO NORTHWEST OREGON
AND SOUTHWEST WASHINGTON THIS EVENING. IT APPEARS THE FIRST RAIN
SHOWERS SHOULD ARRIVE ON THE COAST BETWEEN 4 PM AND 6 PM AND BETWEEN
6 PM AND 9 PM ACROSS THE WILLAMETTE VALLEY. QPF STILL LOOKS RATHER
LIGHT WITH THIS SYSTEM.

THE AREA LOOKS TO DRY OUT RELATIVELY QUICKLY SATURDAY
MORNING...EXCEPT ACROSS THE FAR NORTH WHERE A FEW SHOWERS MAY LINGER
THROUGH THE DAY.

RELATIVELY FLAT RIDGING LOOKS TO BRING DRY AND MILD WEATHER TO THE
AREA LATE SATURDAY THROUGH MONDAY. HOWEVER...AN ATMOSPHERIC RIVER
AIMED AT SOUTHWEST BRITISH COLUMBIA RIVER AND NORTHWEST WASHINGTON
WILL REMAIN CLOSE ENOUGH THAT OUR FAR NORTHWEST ZONES WILL CERTAINLY
SEE INCREASE CLOUD COVER COMPARED TO THEIR COUNTERPARTS FARTHER
SOUTH...AND PERHAPS A PERIOD OR TWO OF LIGHT RAIN DURING THIS PERIOD.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND
252 AM PDT FRI MAR 27 2015

.SYNOPSIS...HIGH PRESSURE WILL LEAD TO ANOTHER DAY WITH ABOVE
AVERAGE TEMPERATURES AND SOME MORNING FOG IN THE LOWLANDS FRIDAY.
HOWEVER...A FRONT WILL SPREAD RAIN SHOWERS INTO THE AREA LATE FRIDAY
WITH POTENTIAL FOR THUNDERSTORMS NEAR THE CASCADE CREST. SHOWERS
DIMINISH WITH A DRYING TREND ON SATURDAY. DRY AND MILD WEATHER LOOKS
TO RETURN LATE SATURDAY THROUGH EARLY MONDAY. ANOTHER FRONT BRINGS
MORE RAIN AND COOLER WEATHER TO THE AREA BEGINNING LATE MONDAY AND
CONTINUES INTO THE MIDDLE OF NEXT WEEK. SNOW LEVELS WILL LIKELY DROP
BELOW CASCADE PASS LEVELS DURING THIS PERIOD.

&&

.SHORT TERM...FRIDAY THROUGH SUNDAY...OBSERVATIONS AND SATELLITE
IMAGERY SHOW FOG JUST STARTING TO DEVELOP IN THE VALLEY THIS MORNING.
LOW STRATUS MOVING UP THE COAST LOOKS LIKE ITS CURRENTLY LOCATED JUST
SOUTH OF NEWPORT AND WILL CONTINUE UP THE COAST THROUGH THE OVERNIGHT
HOURS. HIGH CLOUDS AHEAD OF THE NEXT SYSTEM WILL BEGIN TO MOVE INTO
THE AREA DURING THE MORNING HOURS BUT AT THIS POINT IT LOOKS LIKE THE
RIDGE CURRENTLY IN PLACE WILL HOLD THEM OFF THROUGH THE OVERNIGHT.
WITH LACK OF CLOUD COVER...COULD SEE SOME DENSE FOG AGAIN THIS
MORNING BUT VISIBILITIES SEEM TO BE WAVERING SO FAR SO WILL NOT ISSUE
A DENSE FOG ADVISORY AT THIS POINT.

AS A FRONT APPROACHES THE AREA TODAY...FOG SHOULD DISSIPATE BY AROUND
NOON. MODELS ARE TRENDING A LITTLE SLOWER WITH THE ARRIVAL OF
PRECIP...BUT IT LOOKS LIKE RAIN SHOULD BEGIN ALONG THE COAST BEFORE
00Z AND THEN SPREAD INLAND THROUGH THE LATE AFTERNOON AND EVENING
HOURS. HAVE LEFT A SLIGHT CHANCE OF THUNDER IN FOR THE OREGON
CASCADES THIS AFTERNOON BUT IT MAY BE LIMITED BY AVAILABLE MOISTURE
AS MODELS ARE SHOWING SLIGHTLY HIGHER DEWPOINTS THAN SEEMS COMPLETELY
REASONABLE FOR THE HIGHER TERRAIN. ALTHOUGH SNOW LEVELS WILL BE
DROPPING STEADILY THROUGH SATURDAY...THEY WILL REMAIN ABOVE 7000 FT
FOR THE DURATION OF PRECIP ASSOCIATED WITH THIS FRONT...SO NO
SIGNIFICANT SNOWFALL IS EXPECTED.

A RELATIVELY FLAT RIDGE WILL BUILD INTO THE REGION LATE SATURDAY AND
SUNDAY. HOWEVER MINIMAL RAIN CHANCES WILL LINGER OVER THE NW CORNER
OF THE FORECAST AREA DUE TO ANOTHER SYSTEM PASSING TO THE NORTH
SATURDAY NIGHT INTO SUNDAY. WITH MOSTLY DRY WEATHER
SUNDAY...THOUGH...TEMPERATURES WILL WARM BACK A NUMBER OF DEGREES
ABOVE NORMAL INLAND WITH HIGHS IN THE MID 60S IN THE VALLEY. BOWEN

.LONG TERM (PREVIOUS DISCUSSION)...SUN NIGHT THROUGH THU...OVERALL
PATTERN REMAINS RATHER ZONAL...WITH WESTERLY FLOW ALOFT OVER THE
REGION. THIS MEANS FRONTS WILL PUSH ACROSS THE REGION FROM TIME TO
TIME...BUT NO SIGNIFICANTLY STRONG OR ORGANIZED SYSTEMS EXPECTED.
CLOUDS WILL INCREASE ON MON WITH ANOTHER ROUND OF RAIN FOR LATE IN
THE DAY AND MON NIGHT. LIKELY SEE SHOWERS CONTINUE ON TUE AND TUE
NIGHT AS COOLER AIR ALOFT PUSHES ACROSS REGION.
AFTERWARDS...CONFIDENCE IN ANY SOLUTION BEGINS TO DROP AS MODELS
DIVERGE ON ANY PARTICULAR SOLUTION. WILL TREND TOWARDS DRIER BUT KEEP
SOME MINOR THREAT OF SHOWERS WITH NEAR SEASONABLE TEMPERATURES FOR
SECOND HALF OF NEXT WEEK. ROCKEY.

&&

.AVIATION...MOSTLY VFR CONDITIONS WITH LIGHT WINDS...EXPECT IFR
AND LIFR FOG/LOW STRATUS TO DEVELOP BETWEEN 10-12Z EARLY THIS
MORNING AND LIFT BY 18-20Z LATE THIS MORNING. CONDITIONS WILL
BRIEFLY STAY VFR THROUGH THIS AFTERNOON...BUT SLOWLY DETERIORATE
TOWARDS MVFR BY 08Z SAT AS A COLD FRONT MOVES ACROSS THE REGION.

KPDX AND APPROACHES...VFR CONDITIONS WILL GIVE WAY TO IFR/LIFR
CIGS AND VSBYS BY 12Z THIS MORNING AND REMAIN IN PLACE THROUGH
AT LEAST 18-20Z TODAY. BRIEF VFR CONDITIONS THIS AFTERNOON...THEN
EXPECT CONDITIONS TO SLOWLY DETERIORATE TOWARDS MVFR BETWEEN
04-06Z SAT AS A COLD FRONT MOVES ACROSS THE REGION. /27

&&

.MARINE...BENIGN CONDITIONS PREVAIL THROUGH LATE THIS MORNING
WITH WINDS BELOW 10 KT AND SEAS AROUND 7-8 FT UNDER WEAK HIGH
PRESSURE. A COLD FRONT WILL PUSH INTO THE WATERS THIS AFTERNOON
ALLOWING WINDS TO INCREASE OUT OF THE SOUTH WITH GUSTS TO 25 KT
EXPECTED TO DEVELOP OVER THE OUTER WATERS AHEAD OF THE FRONT.
THE SMALL CRAFT ADVISORY FOR WINDS REMAINS IN EFFECT THROUGH LATE
TONIGHT OVER THE OUTER COASTAL WATERS. WINDS OVER THE INNER
WATERS MAY BRIEFLY CLIMB ABOVE 21 KT...BUT DO NOT FEEL THEY WILL
LAST LONG ENOUGH OR BE WIDESPREAD TO WARRANT AN ADVISORY. SEAS

THE REGION ON FRIDAY. LIFT AHEAD OF THE UPPER LEVEL TROUGH AND
COOLING TEMPERATURES ALOFT MAY INITIATE A FEW SHOWERS AND POSSIBLY A
THUNDERSTORM ACROSS THE CASCADES FRIDAY AFTERNOON. EXPECT THE BULK OF
THE SHOWERS ASSOCIATED WITH THE UPPER LEVEL TROUGH TO ARRIVE ACROSS
NORTHWEST OREGON AND SOUTHWEST WASHINGTON FRIDAY EVENING...LIKELY
CONTINUING FOR MUCH OF THE NIGHT. RAINFALL AMOUNTS SHOULD BE
RELATIVELY LIGHT...LIKELY LESS THAN A HALF INCH IN THE COAST RANGE
AND CASCADES...AND PROBABLY CLOSER TO A TENTH OR TWO TENTHS OF AN
INCH IN THE WILLAMETTE VALLEY.

A LOWERING SUBSIDENCE INVERSION LATE FRIDAY NIGHT SHOULD RESULT IN
SHOWERS BECOMING INCREASINGLY CONFINED TO THE COAST AND CASCADES
BEFORE DECREASING FURTHER SATURDAY MORNING. A RELATIVELY FLAT RIDGE
SHOULD THEN BUILD INTO THE REGION LATE SATURDAY AND SUNDAY AND BRING
ANOTHER ROUND OF ABOVE AVERAGE TEMPERATURES. THIS SHOULD RESULT IN
GENERALLY DRY CONDITIONS ACROSS THE AREA. HOWEVER...MOISTURE
STREAMING NORTHEASTWARD ALONG THE EDGE OF THE HIGH PRESSURE WILL TAKE
AIM AT SOUTHWEST BRITISH COLUMBIA AND NORTHWEST WASHINGTON. AS A
RESULT...THERE IS A CHANCE THIS RAIN COULD SHIFT BRIEFLY INTO FAR
SOUTHWEST WASHINGTON DURING THIS PERIOD. IF NOTHING ELSE...LOW TO
MID LEVEL CLOUDS WILL LIKELY BE A BIT MORE PERSISTENT ACROSS THE
NORTHERN PORTION OF OUR CWA DURING THIS PERIOD. /NEUMAN

ZONAL...WITH WESTERLY FLOW ALOFT OVER THE REGION. THIS MEANS FRONTS
WILL PUSH ACROSS THE REGION FROM TIME TO TIME...BUT NO SIGNIFICANTLY
STRONG OR ORGANIZED SYSTEMS EXPECTED. AFTER A DRY PERIOD SAT NIGHT
THROUGH SUN NIGHT...CLOUDS WILL INCREASE ON MON WITH ANOTHER ROUND
OF RAIN FOR LATE IN THE DAY AND MON NIGHT. LIKELY SEE SHOWERS
CONTINUE ON TUE AND TUE NIGHT AS COOLER AIR ALOFT PUSHES ACROSS
REGION. AFTERWARDS...CONFIDENCE IN ANY SOLUTION BEGINS TO DROP AS
MODELS DIVERGE ON ANY PARTICULAR SOLUTION. WILL TREND TOWARDS DRIER
BUT KEEP SOME MINOR THREAT OF SHOWERS WITH NEAR SEASONABLE
TEMPERATURES FOR SECOND HALF OF NEXT WEEK.   ROCKEY.

.AVIATION...WITH HIGH PRESSURE...CLEAR SKIES...LIGHT WINDS...AND A
MOIST LOWER ATMOSPHERE...CONDITIONS ARE ONCE AGAIN RIPE FOR FOG
DEVELOPMENT. AS SUCH...EXPECT VFR CONDITIONS TO GIVE WAY TO
IFR/LIFR CIGS AND VSBYS AROUND MIDNIGHT. ONCE THE FOG
DEVELOPS...EXPECT IT TO REMAIN IN PLACE INTO TOMORROW MORNING
BEFORE LIFTING BY LATE MORNING. CONDITIONS WILL BRIEFLY RETURN TO
VFR TOMORROW AFTERNOON...BUT SLOWLY DETERIORATE TOWARDS MVFR BY
TOMORROW EVENING AS A COLD FRONT MOVES ACROSS THE REGION.

WINDS...BUT SHOULD REMAIN BELOW 10 FT. /64

REMAINDER OF PREVIOUS DISCUSSION FOLLOWS...WEAK HIGH PRES RETURNS TO
THE WATERS OVER THE WEEKEND. ANOTHER FRONT IS EXPECTED TO MOVE
THROUGH ON MON. THIS FRONT LOOKS A LITTLE MORE IMPRESSIVE AND SHOULD
BRING A SOLID ROUND OF SMALL CRAFT ADVISORY WINDS...WITH A SMALL
