AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
148 AM PDT TUE SEP 2 2014

.SHORT TERM...TODAY THROUGH THURSDAY...THE NORTHWEST FLOW OVER THE
REGION HAS NOW BECOME A WESTERLY FLOW IN RESPONSE TO A TROUGH THAT
IS DIGGING SOUTHWARD ALONG THE COAST. A DRY COLD FRONT EMBEDDED IN
THIS FLOW WILL MOVE THROUGH THE FORECAST AREA TODAY AND TONIGHT.
MOISTURE IS VERY LIMITED SO CAN EXPECT SHOWERS ONLY TO OCCUR OVER
THE CASCADE EAST SLOPES. ELSEWHERE IT WILL REMAIN DRY WITH JUST
CLOUDS OVERHEAD. THE MAIN CONCERN WITH THIS SYSTEM IS TIGHTENING
PRESSURE GRADIENTS AHEAD OF AND WITH THE COLD FRONT. WINDS WILL
REACH THE 20 TO 30 MPH RANGE BY THIS AFTERNOON AND EVENING AS A
RESULT. RELATIVE HUMIDITIES WILL BE HIGH ENOUGH TO KEEP THE BASIN
OUT OF RED FLAG CONDITIONS. HOWEVER...IT WILL BE A CLOSE CALL AND
WILL NEED TO ADD HIGHLIGHTS TO THE FIRE WEATHER FORECAST. THE OTHER
CONCERN WILL BE PATCHY BLOWING DUST IN THE LOWER COLUMBIA BASIN THIS
AFTERNOON AND EVENING. THE ATMOSPHERE WILL BE STABLE SO AM NOT
EXPECTING ANY THUNDERSTORMS. COOLER MARINE AIR WILL FILTER INTO THE
CWA ON WEDNESDAY BEHIND THE DEPARTING COLD FRONT. TEMPERATURES WILL
DROP TO ABOUT 7-10 DEGREES COOLER ON WEDNESDAY THAN TODAY. THE
COOLING WILL BE SHORT LIVED AS 500 MB HEIGHTS AND 850 MB
TEMPERATURES RISE ON THURSDAY WITH LOWER ELEVATION MAXIMUM READINGS
BACK INTO THE LOWER 80S WITH DRY CONDITIONS. THE WARMING TREND WILL
CONTINUE INTO THE LONG TERM FORECAST PERIOD. 88

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...DRY SPLIT FLOW WILL
REMAIN OVER EASTERN WASHINGTON AND OREGON FOR MOST OF THE LONG TERM
PERIOD. THIS WILL KEEP DRY AND STABLE AIR OVER THE AREA. RADIATIONAL
COOLING DUE TO LIGHT WINDS...LENGTHENING NIGHTS...AND CLEAR SKIES
WILL KEEP NIGHTS COOL WHILE THE AMPLIFYING RIDGE WILL PROVIDE SUNNY
SKIES AND WARMER DAYS. SUNDAY NIGHT AND MONDAY AN UPPER LEVEL TROUGH
WITH THE MAIN LIFT IN CANADA MAY DROP FAR ENOUGH SOUTH TO TRIGGER
SOME SHOWERS NEAR THE CASCADES. THE MAIN EFFECTS WILL BE ANOTHER
PUSH OF COOLER AIR FOR LATE SUNDAY AND MONDAY AND SOME BREEZY
CONDITIONS.  COONFIELD

&&

.AVIATION...06Z TAFS...VFR CONDITIONS WILL PREVAIL DURING THE TAF
PERIOD...THOUGH WINDS BTWN 10 TO 20 KTS WITH GUSTS UP TO 30 KTS WILL
OCCUR AS A COLD FRONT PASSES THRU THE AREA BTWN 02/20Z THRU 03/03Z.
THERE IS VERY LIMITED MOISTURE WITH THE FRONT...BUT SCT CIG AOA 10K
FT AGL CAN BE EXPECTED AS IT PASSES.  PATCHY BLOWING DUST MAY OCCUR
NEAR OR OVER KPSC AND KPDT DURING THE STRONGEST WIND GUSTS...THOUGH
BLOWING DUST WILL NOT LIKELY BE THE PREVAILING CONDITION AT THOSE

SHORT TERM...TONIGHT THROUGH THURSDAY...THE NORTHWEST UPPER LEVEL
FLOW OVER THE REGION WILL SHIFT TO A MORE WESTERLY DIRECTION
TONIGHT. THIS IS DUE TO THE APPROACH OF A SYSTEM IN THE GULF OF
ALASKA. THIS FLOW WILL REMAIN DRY THROUGH TONIGHT, THUS WILL SEE
FAIR AND DRY CONDITIONS. LOW END BREEZY WINDS THROUGH THE CASCADE
GAPS THIS EVENING WILL GRADUALLY DECREASE THROUGH THE NIGHT,
ESPECIALLY IN THE GORGE. THE GULF OF ALASKA SYSTEM WILL SWING
THROUGH BRITISH COLUMBIA AND NORTHERN WASHINGTON INTO WESTERN
MONTANA TUESDAY THROUGH WEDNESDAY MORNING. THIS SYSTEM WILL PUSH A
COLD FRONT THROUGH THE REGION TUESDAY AFTERNOON AND EVENING. THIS
FRONT WILL BE LARGELY DRY WITH ONLY SOME LIGHT RAIN NEAR THE CASCADE
CREST (MAINLY IN WASHINGTON) TUESDAY AND TUESDAY NIGHT. ALSO, A FEW
SHOWERS MAY OCCUR OVER THE NORTHERN BLUES AND THE HIGHER TERRAIN IN
WALLOWA COUNTY OVERNIGHT TUESDAY NIGHT. WINDS WILL INCREASE ACROSS
THE AREA BEHIND THE FRONT, ESPECIALLY ACROSS THE COLUMBIA BASIN AND
THROUGH THE CASCADE GAPS. MAY SEE SOME PATCHY BLOWING DUST IN THE
BASIN, BUT AM UNCERTAIN TO HOW MUCH AND HOW LOW VISIBILITIES MAY GO.
MAY JUST SEE A GRADUAL BUILD UP OF DUST IN THE AIR WITH ONLY LIMITED
VISIBILITY REDUCTIONS. THUS WILL HOLD OFF ON ANY HIGHLIGHTS FOR NOW.
THE SYSTEM WILL CONTINUE TO MOVE EAST WEDNESDAY AFTERNOON THROUGH
THURSDAY. THIS WILL RESULT IN A DRY NORTHWEST TO NORTH FLOW
DEVELOPING OVER THE REGION FOR A RETURN TO LIGHTER WINDS AND DRY
CONDITIONS. 90

LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE AREA WILL REMAIN
DRY THROUGH MUCH OF PERIOD AS AN UPPER LOW MOVES DOWN OVER NORTHERN
CALIFORNIA AND A RIDGE OF HIGHER PRESSURE PUSHES INTO WASHINGTON.
THE NEXT SYSTEM WILL BE DROPPING SOUTH THROUGH WESTERN CANADA ON
SUNDAY AND MONDAY.  THE 12Z GFS IS STRONGER AND DIVES THE SYSTEM
SOUTH OVER WASHINGTON...WHILE THE ECMWF IS ABOUT 12 HOURS SLOWER AND
KEEPS THE BEST ENERGY AND MOISTURE TO THE NORTH, SIMILAR TO THE
PREVIOUS GFS RUNS. THIS SYSTEM SHOULD BRING SOME SHOWERS TO THE
WASHINGTON CASCADES BUT WE SHOULD NOT SEE ANY FURTHER SOUTH. THE

SHORT TERM...TONIGHT THROUGH THURSDAY...THE NORTHWEST UPPER LEVEL
FLOW OVER THE REGION WILL SHIFT TO A MORE WESTERLY DIRECTION
TONIGHT. THIS IS DUE TO THE APPROACH OF A SYSTEM IN THE GULF OF
ALASKA. THIS FLOW WILL REMAIN DRY THROUGH TONIGHT, THUS WILL SEE
FAIR AND DRY CONDITIONS. LOW END BREEZY WINDS THROUGH THE CASCADE
GAPS THIS EVENING WILL GRADUALLY DECREASE THROUGH THE NIGHT,
ESPECIALLY IN THE GORGE. THE GULF OF ALASKA SYSTEM WILL SWING
THROUGH BRITISH COLUMBIA AND NORTHERN WASHINGTON INTO WESTERN
MONTANA TUESDAY THROUGH WEDNESDAY MORNING. THIS SYSTEM WILL PUSH A
COLD FRONT THROUGH THE REGION TUESDAY AFTERNOON AND EVENING. THIS
FRONT WILL BE LARGELY DRY WITH ONLY SOME LIGHT RAIN NEAR THE CASCADE
CREST (MAINLY IN WASHINGTON) TUESDAY AND TUESDAY NIGHT. ALSO, A FEW
SHOWERS MAY OCCUR OVER THE NORTHERN BLUES AND THE HIGHER TERRAIN IN
WALLOWA COUNTY OVERNIGHT TUESDAY NIGHT. WINDS WILL INCREASE ACROSS
THE AREA BEHIND THE FRONT, ESPECIALLY ACROSS THE COLUMBIA BASIN AND
THROUGH THE CASCADE GAPS. MAY SEE SOME PATCHY BLOWING DUST IN THE
BASIN, BUT AM UNCERTAIN TO HOW MUCH AND HOW LOW VISIBILITIES MAY GO.
MAY JUST SEE A GRADUAL BUILD UP OF DUST IN THE AIR WITH ONLY LIMITED
VISIBILITY REDUCTIONS. THUS WILL HOLD OFF ON ANY HIGHLIGHTS FOR NOW.
THE SYSTEM WILL CONTINUE TO MOVE EAST WEDNESDAY AFTERNOON THROUGH
THURSDAY. THIS WILL RESULT IN A DRY NORTHWEST TO NORTH FLOW
DEVELOPING OVER THE REGION FOR A RETURN TO LIGHTER WINDS AND DRY
CONDITIONS. 90

LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE AREA WILL REMAIN
DRY THROUGH MUCH OF PERIOD AS AN UPPER LOW MOVES DOWN OVER NORTHERN
CALIFORNIA AND A RIDGE OF HIGHER PRESSURE PUSHES INTO WASHINGTON.
THE NEXT SYSTEM WILL BE DROPPING SOUTH THROUGH WESTERN CANADA ON
SUNDAY AND MONDAY.  THE 12Z GFS IS STRONGER AND DIVES THE SYSTEM
SOUTH OVER WASHINGTON...WHILE THE ECMWF IS ABOUT 12 HOURS SLOWER AND
KEEPS THE BEST ENERGY AND MOISTURE TO THE NORTH, SIMILAR TO THE
PREVIOUS GFS RUNS. THIS SYSTEM SHOULD BRING SOME SHOWERS TO THE
WASHINGTON CASCADES BUT WE SHOULD NOT SEE ANY FURTHER SOUTH. THE
MAIN EFFECTS WILL BE ANOTHER PUSH OF COOLER AIR FOR LATE SUNDAY AND

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
921 PM PDT MON SEP  1 2014

.SYNOPSIS...MARINE STRATUS IS FORMING IN NW FLOW ALONG THE COAST THIS
EVENING SHOULD SOLIDIFY OVER THE NEXT FEW HOURS AND PUSH PARTIALLY
INLAND OVERNIGHT. AN UPPER LEVEL TROUGH WILL MOVE ACROSS THE REGION
TUESDAY INTO EARLY WEDNESDAY BRINING COOLER AND CLOUDY WEATHER. THIS
SYSTEM MAY ALSO BRING SOME LIGHT RAIN TO SOUTHWEST WASHINGTON AND THE
FAR NORTHERN PART OF NORTHWEST OREGON TUESDAY AFTERNOON AND TUESDAY
NIGHT. AN UPPER LEVEL RIDGE COMBINED WITH LOW-LEVEL EASTERLY WINDS
WILL RESULT IN SUNNIER AND WARMER WEATHER FOR THE LATTER PART OF THE
WEEK. ONSHORE FLOW WILL RETURN NEXT SUNDAY.

&&

.SHORT TERM...TONIGHT THROUGH THURSDAY...CLOUDS CLEARED FOR MOST
EVERYONE DURING THE LATE AFTERNOON AND EARLY EVENING HOURS.
HOWEVER...THE LATEST OBSERVATIONS AND SATELLITE FOG PRODUCT ARE
SHOWING MARINE STRATUS BEGINNING TO REFORM ALONG THE COAST IN NW
FLOW. EXPECT THE MARINE CLOUDS TO CONTINUE TO SOLIDIFY OVER THE NEXT
FEW HOURS...THEN PUSH AT LEAST PARTIALLY INLAND OVERNIGHT INTO
TOMORROW MORNING. THERE IS BETTER ONSHORE GRADIENT AT CURRENT THAN WE
SAW 24 HRS AGO...SO THINK THE CLOUDS WILL AT LEAST FILL IN THE LOWER
COLUMBIA BASIN UP TO THE PORTLAND/VANCOUVER METRO AREA. LESS CLEAR IS
WHETHER CLOUDS WILL FILL THE ENTIRE WILLAMETTE VALLEY. IT IS POSSIBLE
THAT THE CLOUDS WILL GET ENOUGH EXTRA PUSH FROM AN INCOMING UPPER
LEVEL TROUGH AFTER SUNRISE TOMORROW.

THE AFOREMENTIONED UPPER TROUGH WILL DIVE SOUTH FROM BRITISH COLUMBIA
INTO WASHINGTON DURING THE DAY TOMORROW. A WEAK ASSOCIATED FRONT WILL
MOVE ACROSS THE NORTHERN PART OF THE REGION IN THE AFTERNOON AND
EVENING.  THE FRONT MAY PRODUCE SOME LIGHT RAIN ALONG THE NORTH
COAST/COAST RANGE AND PART OF THE INLAND AREA. BEST CHANCES OF
MEASURABLE RAIN WILL BE IN SOUTHWEST WA...BUT THE NORTHERN WILLAMETTE
VALLEY AND ADJACENT FOOTHILLS AND NORTH CASCADES WILL BE ON THE
SOUTHERN END OF THE FRONT AND COULD GET A LITTLE RAIN AS WELL.THERE
WILL BE ANOTHER DEEP MARINE PUSH TOMORROW NIGHT WITH A CLOUDY START
TO THE DAY ON WEDNESDAY. THE UPPER TROUGH AND INCREASE IN CLOUDS WILL
KEEP THE TEMPERATURES BELOW NORMAL TUESDAY AND WEDNESDAY.

HIGH PRESSURE WILL REBUILD OVER THE REGION THURSDAY. A FAIRLY STRONG
THERMAL TROUGH WILL ALSO BUILD NORTHWARD ALONG THE COAST. THIS WILL
RESULT IN OFFSHORE FLOW...CLEAR SKIES...AND WARMER TEMPERATURES
THE LATTER PART OF THE WORK WEEK. PYLE/TW

.LONG TERM...FRIDAY THROUGH MONDAY...A WEAK...POSITIVELY-TILTED
TROUGH WILL MOVE THROUGH OUR AREA LATE THIS WEEK.  NOT ONLY IS
MOISTURE LIMITED FOR THE PASSAGE OF THIS SYSTEM...BUT ANY
PRECIPITATION THAT DOES DEVELOP SHOULD BE EAST OF THE CASCADE
RIDGE...OUTSIDE OF OUR AREA.  LATE THIS WEEKEND THE
GFS...ECMWF...AND DGEX ALL ARE SUGGESTING A LONGWAVE TROUGH WILL
MOVE ONSHORE BRINGING A CHANCE FOR SOME RAINFALL SUNDAY NIGHT OR
MONDAY. DISAGREEMENT BETWEEN MODELS ON TIMING AND BECAUSE OF HOW FAR
OUT THIS SYSTEM IS IN THE FORECAST PERIOD...THERE IS A LOT OF
UNCERTAINTY WITH THIS SYSTEM. KEPT POPS THE SAME AS THEY CAPTURE
THIS UNCERTAINTY WELL. -MCCOY
&&

.AVIATION...HIGH PRESSURE WILL BUILD IN OVERNIGHT ALLOWING THE
MARINE INVERSION TO LOWER SOME ACROSS THE AREA. CLOUDS CLEARED ALL
BUT THE NORTH COAST THIS AFTERNOON AND EXPECT STRATUS TO DEVELOP
ALONG THE SOUTH WASHINGTON AND NORTH OREGON COAST BEFORE MIDNIGHT
WITH MOSTLY MVFR CIGS BUT THIS DECK COULD LOWER TO IFR 11Z-16Z.
FROM FLORENCE TO KONP EXPECT MORE IFR LOW CIGS AND VIS TO DEVELOP
AFT 06Z...CAN ALREADY SEE SOME FOG OR LOW CLOUDS OFF THE COAST IN
THE SATELLITE IMAGERY. MODELS INDICATE THAT MVFR STRATUS WILL
MOVE DOWN THE COLUMBIA RIVER GAP INTO KSPB-KTTD AFTER 10Z OR SO
AND PROBABLY TO KSLE 13-19Z. MODELS INDICATE THAT A WEEK FRONT
WILL PUSH DOWN THE COAST LATE TUE AFTERNOON AND SPREAD SOME LIGHT
RAIN TO THE NORTH COAST AND NORTH INLAND TUESDAY EVENING WITH SOME
MVFR CIGS MAINLY ALONG THE COAST. SCHNEIDER


KPDX AND APPROACHES...VFR CONDITIONS THIS EVENING. STRATUS
DEVELOPING AFTER AROUND 10Z WITH MVFR CIGS LIKELY THROUGH 19-20Z.

.MARINE...MARINE WINDS HAVE BEEN A LITTLE LIGHTER THAN PREVIOUSLY
ANTICIPATED AND HAVE LOWERED THE SMALL CRAFT ADVISORY FOR THE
CENTRAL COASTAL WATERS OF OREGON. HIGH PRESSURE WILL REBUILD
OVERNIGHT AND TOMORROW MORNING BUT A WEAK FRONT WILL APPROACH THE
NORTHERN WATERS TUE AFTERNOON RESULTING IN MORE WESTERLY WINDS
BRIEFLY UNTIL THE FRONT PASSES TUESDAY EVENING AND HIGH PRESSURE
BEGINS TO BUILD...WITH THE MAIN EFFECT BEING SOME MODERATE NW
WINDS BEHIND THE FRONT THAT MAY GIVE SOME GUSTS ABOVE 20 KT
ESPECIALLY
IN THE OUTER WATERS. THE THERMAL TROUGH BEGINS REDEVELOPING IN
NORTHERN CALIFORNIA WEDNESDAY...WITH SMALL CRAFT ADVISORY
THRESHOLD NORTHERLY WINDS BEGINNING TO SPREAD NORTH ALONG THE
CENTRAL OREGON COAST LATE WEDNESDAY. THE WINDS WILL THEN SPREAD
NORTHWARD THROUGH ALL THE WATERS THURSDAY AND FRIDAY AS THE
THERMAL TROUGH CONTINUES TO BUILDS FARTHER NORTH ALONG THE COAST.
WINDS THURSDAY AFTERNOON AND EVENING WILL BE ON THE HIGH SIDE OF
THE SMALL CRAFT ADVISORY RANGE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
921 PM PDT MON SEP  1 2014

.SYNOPSIS...MARINE STRATUS IS FORMING IN NW FLOW ALONG THE COAST THIS
EVENING SHOULD SOLIDIFY OVER THE NEXT FEW HOURS AND PUSH PARTIALLY
INLAND OVERNIGHT. AN UPPER LEVEL TROUGH WILL MOVE ACROSS THE REGION
TUESDAY INTO EARLY WEDNESDAY BRINING COOLER AND CLOUDY WEATHER. THIS
SYSTEM MAY ALSO BRING SOME LIGHT RAIN TO SOUTHWEST WASHINGTON AND THE
FAR NORTHERN PART OF NORTHWEST OREGON TUESDAY AFTERNOON AND TUESDAY
NIGHT. AN UPPER LEVEL RIDGE COMBINED WITH LOW-LEVEL EASTERLY WINDS
WILL RESULT IN SUNNIER AND WARMER WEATHER FOR THE LATTER PART OF THE
WEEK. ONSHORE FLOW WILL RETURN NEXT SUNDAY.

&&

.SHORT TERM...TONIGHT THROUGH THURSDAY...CLOUDS CLEARED FOR MOST
EVERYONE DURING THE LATE AFTERNOON AND EARLY EVENING HOURS.
HOWEVER...THE LATEST OBSERVATIONS AND SATELLITE FOG PRODUCT ARE
SHOWING MARINE STRATUS BEGINNING TO REFORM ALONG THE COAST IN NW
FLOW. EXPECT THE MARINE CLOUDS TO CONTINUE TO SOLIDIFY OVER THE NEXT
FEW HOURS...THEN PUSH AT LEAST PARTIALLY INLAND OVERNIGHT INTO
TOMORROW MORNING. THERE IS BETTER ONSHORE GRADIENT AT CURRENT THAN WE
SAW 24 HRS AGO...SO THINK THE CLOUDS WILL AT LEAST FILL IN THE LOWER
COLUMBIA BASIN UP TO THE PORTLAND/VANCOUVER METRO AREA. LESS CLEAR IS
WHETHER CLOUDS WILL FILL THE ENTIRE WILLAMETTE VALLEY. IT IS POSSIBLE
THAT THE CLOUDS WILL GET ENOUGH EXTRA PUSH FROM AN INCOMING UPPER
LEVEL TROUGH AFTER SUNRISE TOMORROW.

THE AFOREMENTIONED UPPER TROUGH WILL DIVE SOUTH FROM BRITISH COLUMBIA
INTO WASHINGTON DURING THE DAY TOMORROW. A WEAK ASSOCIATED FRONT WILL
MOVE ACROSS THE NORTHERN PART OF THE REGION IN THE AFTERNOON AND
EVENING.  THE FRONT MAY PRODUCE SOME LIGHT RAIN ALONG THE NORTH
COAST/COAST RANGE AND PART OF THE INLAND AREA. BEST CHANCES OF
MEASURABLE RAIN WILL BE IN SOUTHWEST WA...BUT THE NORTHERN WILLAMETTE
VALLEY AND ADJACENT FOOTHILLS AND NORTH CASCADES WILL BE ON THE
SOUTHERN END OF THE FRONT AND COULD GET A LITTLE RAIN AS WELL.THERE
WILL BE ANOTHER DEEP MARINE PUSH TOMORROW NIGHT WITH A CLOUDY START
TO THE DAY ON WEDNESDAY. THE UPPER TROUGH AND INCREASE IN CLOUDS WILL
KEEP THE TEMPERATURES BELOW NORMAL TUESDAY AND WEDNESDAY.

HIGH PRESSURE WILL REBUILD OVER THE REGION THURSDAY. A FAIRLY STRONG

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
801 PM PDT MON SEP 1 2014

.DISCUSSION...02/00Z NAM IN.

CLEAR SKIES PREVAIL ACROSS THE MEDFORD CWA THIS EVENING...EXCEPT
FOR SOME MARINE STRATUS WELL OFFSHORE. LOTS OF SMOKE CONTINUES TO
EMANATE FROM THE WESTERN SISKIYOU COUNTY FIRES...THOUGH THAT IS
MOSTLY GOING SOUTH TO SOUTHWEST AT THIS TIME.

A WARM AND DRY RIDGE OVER THE AREA WILL FLATTEN OUT TONIGHT INTO
TUESDAY AS A STRONG SHORT WAVE RIDES OVER THE TOP OF IT. THE WAVE
WILL MOVE ONSHORE TUESDAY. THE WAVE WILL CARVE OUT A TROUGH THAT
WILL THEN SHEAR...LEAVING A RESIDUAL TROUGH OVER THE PACIFIC
NORTHWEST WEDNESDAY.

OFFSHORE LOW LEVEL FLOW IS IN PLACE OVER THE AREA...ALTHOUGH IT
DID TURN ONSHORE FOR A WHILE MONDAY AFTERNOON. THE DIGGING TROUGH
WILL PUSH A COLD FRONT ONSHORE TUESDAY NIGHT...WHICH WILL STALL
OVER THE NORTHERN PORTIONS OF THE AREA AND THEN WASH OUT AS THE
UPPER LEVEL SUPPORT DEPARTS. THIS WILL BE A DRY SYSTEM AND THE
MAIN EFFECT WILL BE TO INCREASE WINDS OVER THE RIDGES AND EAST OF
THE CASCADES...WHICH IS PRIMARILY A FIRE WEATHER CONCERN...AND
OVER THE COASTAL WATERS...WHICH IS A MARINE CONCERN. MARINE
STRATUS WILL INCREASE AND SOME OF IT WILL PUSH INLAND BEHIND THE
FRONT TUESDAY NIGHT...BUT IT WILL BE LIMITED TO THE COASTAL
VALLEYS AND THE LOWER UMPQUA BASIN. THE REST OF THE AREA WILL
REMAIN CLEAR. INLAND TEMPERATURES TUESDAY WILL BE 5-10 DEGREES
ABOVE NORMAL...COOLING TO AROUND NORMAL WEDNESDAY. OFFSHORE FLOW
WILL RETURN WEDNESDAY NIGHT AS THE UPPER TROUGH DEPARTS...AND WILL
CONTINUE THROUGH THURSDAY NIGHT.

EXTENDED DISCUSSION FROM THE MONDAY AFTERNOON AFD...FRIDAY THROUGH
MONDAY. THE THERMAL TROUGH WILL THEN EXPAND NORTHWARDS THROUGH
THE WEEK, RESULTING IN TEMPERATURES ACROSS THE AREA THAT ARE MORE
AKIN TO EARLY AUGUST THAN EARLY SEPTEMBER. IN FACT, MOST AREAS CAN
EXPECT TO SEE DAY TIME HIGH TEMPERATURES OF 10 TO 15 DEGREES ABOVE
NORMAL BY THE WEEKEND.

THERE MAY BE SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE
PRODUCING A STRONGER, AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING
THE PACIFIC NORTHWEST. HOWEVER, THE SYSTEM HAS BEEN TRENDING
DRYER AND SLOWER OVER THE PAST SEVERAL RUNS. UNCERTAINTY IS VERY
HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE FORECAST AT THIS
TIME. -BPN

&&

.AVIATION...BASED ON THE 02/00Z TAF CYCLE...CLEAR SKIES WILL
PREVAIL INLAND FOR THE NEXT 24 HOURS WITH THE EXCEPTION OF REDUCED
VISIBILITY IN SISKIYOU COUNTY DUE TO SMOKE FROM WILDFIRES IN THE
WESTERN PORTION OF SISKIYOU COUNTY. MARINE STRATUS WILL RETURN TO
THE COASTAL WATERS NORTH OF CAPE BLANCO AND TO THE NORTH BEND AREA
BETWEEN 9-10Z, BUT WILL CLEAR OUT BY MID MORNING. -PETRUCELLI

&&

.MARINE...UPDATED 300 PM PDT MON 1 SEP 2014...AN ACTIVE WEEK IS IN
STORE WITH GALES AND HAZARDOUS SEAS LIKELY OVER THE SOUTHERN WATERS
FROM CAPE ARGO SOUTH AND 10 NM FROM SHORE TUESDAY AFTERNOON AND
THIS IS LIKELY TO EXPAND NORTH JUST WEST OF CAPE BLANCO TUESDAY
NIGHT. STEEP WIND DRIVEN SEAS ARE ALSO LIKELY WITH COMBINED SEAS UP
TO 15 FT SEAS POSSIBLE IN THE SOUTHERN WATERS WEDNESDAY AFTERNOON
AND EVENING. WINDS ALONG THE COAST OUT TO 5 NM ARE NOT EXPECTED TO
BE AS STRONG, HOWEVER WIND DRIVEN SEAS FROM THE OUTER WATERS WILL
MOVE TOWARDS THE COAST CAUSING THEM TO BE CHOPPY. THE THERMAL TROUGH
SHOULD SHIFT WEST FRIDAY WHICH SHOULD RESULT IN DECREASING WINDS AND
SEAS. -PETRUCELLI

&&

.FIRE WEATHER...VERY ACTIVE FIRE WEATHER PATTERN THIS WEEK STARTS
WITH THE THERMAL TROUGH MOVING INLAND TOMORROW. THIS WILL BRING
INCREASED INSTABILITY TO THE REGION..ESPECIALLY THE CASCADES...WITH
INCREASED WESTERLY WINDS ON THE WEST SIDE. A DRY COLD FRONT MOVING
THROUGH THE REGION ALSO INCREASES WINDS A BIT. BEHIND THE FRONT RH`S
DROP QUICKLY..ESPECIALLY AT THE RIDGE LEVEL WITH INCREASING WINDS
THAT BECOME OFFSHORE ACROSS THE EAST SIDE BY THURSDAY MORNING.
COOLER AIR MOVES IN ALOFT SATURDAY BRINGING INCREASED INSTABILITY.
HOWEVER THE FLOW PRECEDING IT IS FROM THE EAST AND THERE WILL NOT
BE ENOUGH MOISTURE TO ALLOW ANY DEEP CONVECTION TO FORM.

PLACE...THEREFORE CONDITIONS SHOULD REMAIN FAIR WITH LITTLE TO NO
PROBABILITY OF PRECIPITATION TONIGHT. BREEZY CONDITIONS THROUGH THE
CASCADE GAPS AND THE COLUMBIA RIVER GORGE WILL START TO TAPER

WILL ENTER THE AREA BRINGING A COLD FRONT ACROSS THE REGION DURING
THE AFTERNOON TO EARLY EVENING HOURS. GIVEN WESTERLY FLOW OVER THE
AREA...BEST CHANCE OF PRECIPITATION WILL REMAIN OVER THE EASTERN
SLOPES OF THE WASHINGTON CASCADES. MAIN CONCERN WITH THIS FRONTAL
PASSAGE WILL BE THE GUSTY WINDS WHICH MAY CAUSE PATCHY BLOWING
DUST TO OCCUR ACROSS THE LOWER COLUMBIA BASIN. SOME SLIGHT
ADJUSTMENTS TO TEMPERATURE AND WINDS WERE MADE...OTHERWISE THE
REST OF THE FORECAST REMAINS ON TRACK. BIEDA

.PREV DISC... /ISSUED 245 PM PDT MON SEP 1 2014/

SHORT TERM...TONIGHT THROUGH THURSDAY...THE NORTHWEST UPPER LEVEL
FLOW OVER THE REGION WILL SHIFT TO A MORE WESTERLY DIRECTION
TONIGHT. THIS IS DUE TO THE APPROACH OF A SYSTEM IN THE GULF OF
ALASKA. THIS FLOW WILL REMAIN DRY THROUGH TONIGHT, THUS WILL SEE
FAIR AND DRY CONDITIONS. LOW END BREEZY WINDS THROUGH THE CASCADE
GAPS THIS EVENING WILL GRADUALLY DECREASE THROUGH THE NIGHT,
ESPECIALLY IN THE GORGE. THE GULF OF ALASKA SYSTEM WILL SWING
THROUGH BRITISH COLUMBIA AND NORTHERN WASHINGTON INTO WESTERN
MONTANA TUESDAY THROUGH WEDNESDAY MORNING. THIS SYSTEM WILL PUSH A
COLD FRONT THROUGH THE REGION TUESDAY AFTERNOON AND EVENING. THIS
FRONT WILL BE LARGELY DRY WITH ONLY SOME LIGHT RAIN NEAR THE CASCADE
CREST (MAINLY IN WASHINGTON) TUESDAY AND TUESDAY NIGHT. ALSO, A FEW
SHOWERS MAY OCCUR OVER THE NORTHERN BLUES AND THE HIGHER TERRAIN IN
WALLOWA COUNTY OVERNIGHT TUESDAY NIGHT. WINDS WILL INCREASE ACROSS
THE AREA BEHIND THE FRONT, ESPECIALLY ACROSS THE COLUMBIA BASIN AND
THROUGH THE CASCADE GAPS. MAY SEE SOME PATCHY BLOWING DUST IN THE
BASIN, BUT AM UNCERTAIN TO HOW MUCH AND HOW LOW VISIBILITIES MAY GO.
MAY JUST SEE A GRADUAL BUILD UP OF DUST IN THE AIR WITH ONLY LIMITED
VISIBILITY REDUCTIONS. THUS WILL HOLD OFF ON ANY HIGHLIGHTS FOR NOW.
THE SYSTEM WILL CONTINUE TO MOVE EAST WEDNESDAY AFTERNOON THROUGH
THURSDAY. THIS WILL RESULT IN A DRY NORTHWEST TO NORTH FLOW
DEVELOPING OVER THE REGION FOR A RETURN TO LIGHTER WINDS AND DRY
CONDITIONS. 90

LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE AREA WILL REMAIN
DRY THROUGH MUCH OF PERIOD AS AN UPPER LOW MOVES DOWN OVER NORTHERN
CALIFORNIA AND A RIDGE OF HIGHER PRESSURE PUSHES INTO WASHINGTON.
THE NEXT SYSTEM WILL BE DROPPING SOUTH THROUGH WESTERN CANADA ON
SUNDAY AND MONDAY.  THE 12Z GFS IS STRONGER AND DIVES THE SYSTEM
SOUTH OVER WASHINGTON...WHILE THE ECMWF IS ABOUT 12 HOURS SLOWER AND
KEEPS THE BEST ENERGY AND MOISTURE TO THE NORTH, SIMILAR TO THE
PREVIOUS GFS RUNS. THIS SYSTEM SHOULD BRING SOME SHOWERS TO THE
WASHINGTON CASCADES BUT WE SHOULD NOT SEE ANY FURTHER SOUTH. THE MAIN
EFFECTS WILL BE ANOTHER PUSH OF COOLER AIR FOR LATE SUNDAY AND
MONDAY AND SOME BREEZY CONDITIONS. ML

AVIATION...00Z TAFS...VFR CONDITIONS WILL PREVAIL OVER THE NEXT 24
HOURS UNDER MOSTLY CLEAR SKIES. WINDS WILL DECREASE TO LESS THAN 10
KTS OVERNIGHT AND THEN INCREASE AFTER 18Z ON TUESDAY WITH MOST

.DISCUSSION...THE THERMAL TROUGH CONTINUES TO BE THE PRIMARY
DRIVER BEHIND THE FORECAST FOR THE NEXT WEEK. THE ONLY QUESTION IS
HOW STRONG IT WILL GET AND HOW FAR NORTH IT WILL EXPAND. MODELS
ARE IN GOOD AGREEMENT WITH THE GENERAL PROGRESSION, BUT HAVE
DEVELOPED DIFFERENCES IN REGARDS TO THE DETAILS, ESPECIALLY IN
THE EXTENDED PERIOD. OVERALL, CONFIDENCE REMAINS HIGH IN A DRY AND
VERY WARM WEEK, AGAIN WITH NEARLY NO INDICATION OF PRECIPITATION
ANYTIME SOON. SMOKE AND HAZE WILL CONTINUE TO BE AN ISSUE THROUGH
THE WEEK, ESPECIALLY OVER NORTHERN CALIFORNIA AND IN THE VICINITY OF
ANY OTHER FIRES THAT CONTINUE TO BURN IN THE AREA.

A DRY COLD FRONT WILL APPROACH THE REGION TOMORROW NIGHT, HOWEVER
THE COOLER AIR WILL NOT BE ABLE TO PENETRATE VERY FAR INTO THE
FORECAST AREA. THE MAJOR IMPACT OF THE FRONT WILL BE TO INCREASE
THE TEMPERATURE DIFFERENCE BETWEEN THE THERMAL TOUGH TO THE SOUTH
AND THE COOLER AIR TO THE NORTH. THE RESULT WILL BE INCREASED
OFFSHORE WINDS THROUGH THURSDAY AND VERY DRY AIR OVER THE AREA.
THE THERMAL TROUGH WILL THEN EXPAND NORTHWARDS THROUGH THE
WEEK, RESULTING IN TEMPERATURES ACROSS THE AREA THAT ARE MORE
AKIN TO EARLY AUGUST THAN EARLY SEPTEMBER. IN FACT, MOST AREAS CAN
EXPECT TO SEE DAY TIME HIGH TEMPERATURES OF 10 TO 15 DEGREES ABOVE
NORMAL BY THE WEEKEND.

THERE MAY BE SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE
PRODUCING A STRONGER, AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING
THE PACIFIC NORTHWEST. HOWEVER, THE SYSTEM HAS BEEN TRENDING
DRYER AND SLOWER OVER THE PAST SEVERAL RUNS. UNCERTAINTY IS VERY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
251 PM PDT MON SEP 1 2014

.DISCUSSION...THE THERMAL TROUGH CONTINUES TO BE THE PRIMARY
DRIVER BEHIND THE FORECAST FOR THE NEXT WEEK. THE ONLY QUESTION IS
HOW STRONG IT WILL GET AND HOW FAR NORTH IT WILL EXPAND. MODELS
ARE IN GOOD AGREEMENT WITH THE GENERAL PROGRESSION, BUT HAVE
DEVELOPED DIFFERENCES IN REGARDS TO THE DETAILS, ESPECIALLY IN
THE EXTENDED PERIOD. OVERALL, CONFIDENCE REMAINS HIGH IN A DRY AND
VERY WARM WEEK, AGAIN WITH NEARLY NO INDICATION OF PRECIPITATION
ANYTIME SOON. SMOKE AND HAZE WILL CONTINUE TO BE AN ISSUE THROUGH
THE WEEK, ESPECIALLY OVER NORTHERN CALIFORNIA AND IN THE VICINITY OF
ANY OTHER FIRES THAT CONTINUE TO BURN IN THE AREA.

A DRY COLD FRONT WILL APPROACH THE REGION TOMORROW NIGHT, HOWEVER
THE COOLER AIR WILL NOT BE ABLE TO PENETRATE VERY FAR INTO THE
FORECAST AREA. THE MAJOR IMPACT OF THE FRONT WILL BE TO INCREASE
THE TEMPERATURE DIFFERENCE BETWEEN THE THERMAL TOUGH TO THE SOUTH
AND THE COOLER AIR TO THE NORTH. THE RESULT WILL BE INCREASED
OFFSHORE WINDS THROUGH THURSDAY AND VERY DRY AIR OVER THE AREA.
THE THERMAL TROUGH WILL THEN EXPAND NORTHWARDS THROUGH THE
WEEK, RESULTING IN TEMPERATURES ACROSS THE AREA THAT ARE MORE
AKIN TO EARLY AUGUST THAN EARLY SEPTEMBER. IN FACT, MOST AREAS CAN
EXPECT TO SEE DAY TIME HIGH TEMPERATURES OF 10 TO 15 DEGREES ABOVE

NATIONAL WEATHER SERVICE PENDLETON OR
245 PM PDT MON SEP 1 2014

.SHORT TERM...TONIGHT THROUGH THURSDAY...THE NORTHWEST UPPER LEVEL
FLOW OVER THE REGION WILL SHIFT TO A MORE WESTERLY DIRECTION
TONIGHT. THIS IS DUE TO THE APPROACH OF A SYSTEM IN THE GULF OF
ALASKA. THIS FLOW WILL REMAIN DRY THROUGH TONIGHT, THUS WILL SEE
FAIR AND DRY CONDITIONS. LOW END BREEZY WINDS THROUGH THE CASCADE
GAPS THIS EVENING WILL GRADUALLY DECREASE THROUGH THE NIGHT,
ESPECIALLY IN THE GORGE. THE GULF OF ALASKA SYSTEM WILL SWING
THROUGH BRITISH COLUMBIA AND NORTHERN WASHINGTON INTO WESTERN
MONTANA TUESDAY THROUGH WEDNESDAY MORNING. THIS SYSTEM WILL PUSH A
COLD FRONT THROUGH THE REGION TUESDAY AFTERNOON AND EVENING. THIS
FRONT WILL BE LARGELY DRY WITH ONLY SOME LIGHT RAIN NEAR THE CASCADE
CREST (MAINLY IN WASHINGTON) TUESDAY AND TUESDAY NIGHT. ALSO, A FEW
SHOWERS MAY OCCUR OVER THE NORTHERN BLUES AND THE HIGHER TERRAIN IN
WALLOWA COUNTY OVERNIGHT TUESDAY NIGHT. WINDS WILL INCREASE ACROSS
THE AREA BEHIND THE FRONT, ESPECIALLY ACROSS THE COLUMBIA BASIN AND
THROUGH THE CASCADE GAPS. MAY SEE SOME PATCHY BLOWING DUST IN THE
BASIN, BUT AM UNCERTAIN TO HOW MUCH AND HOW LOW VISIBILITIES MAY GO.
MAY JUST SEE A GRADUAL BUILD UP OF DUST IN THE AIR WITH ONLY LIMITED
VISIBILITY REDUCTIONS. THUS WILL HOLD OFF ON ANY HIGHLIGHTS FOR NOW.
THE SYSTEM WILL CONTINUE TO MOVE EAST WEDNESDAY AFTERNOON THROUGH
THURSDAY. THIS WILL RESULT IN A DRY NORTHWEST TO NORTH FLOW
DEVELOPING OVER THE REGION FOR A RETURN TO LIGHTER WINDS AND DRY
CONDITIONS. 90

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE AREA WILL REMAIN
DRY THROUGH MUCH OF PERIOD AS AN UPPER LOW MOVES DOWN OVER NORTHERN
CALIFORNIA AND A RIDGE OF HIGHER PRESSURE PUSHES INTO WASHINGTON.
THE NEXT SYSTEM WILL BE DROPPING SOUTH THROUGH WESTERN CANADA ON
SUNDAY AND MONDAY.  THE 12Z GFS IS STRONGER AND DIVES THE SYSTEM
SOUTH OVER WASHINGTON...WHILE THE ECMWF IS ABOUT 12 HOURS SLOWER AND
KEEPS THE BEST ENERGY AND MOISTURE TO THE NORTH, SIMILAR TO THE
PREVIOUS GFS RUNS. THIS SYSTEM SHOULD BRING SOME SHOWERS TO THE
WASHINGTON CASCADES BUT WE SHOULDNT SEE ANY FURTHER SOUTH. THE MAIN
EFFECTS WILL BE ANOTHER PUSH OF COOLER AIR FOR LATE SUNDAY AND
MONDAY AND SOME BREEZY CONDITIONS. ML

&&

.AVIATION...00Z TAFS...VFR CONDITIONS WILL PREVAIL OVER THE NEXT 24
HOURS UNDER MOSTLY CLEAR SKIES. WINDS WILL DECREASE TO LESS THAN 10

COAST THIS EVENING...OTHERWISE IT WILL BE MOSTLY CLEAR.  AN UPPER
LEVEL TROUGH WILL MOVE ACROSS THE REGION TUESDAY INTO EARLY
WEDNESDAY BRINING COOLER AND CLOUDY WEATHER. THIS SYSTEM WILL ALSO
BRING SOME LIGHT RAIN TO SOUTHWEST WASHINGTON AND THE FAR NORTHERN
PART OF NORTHWEST OREGON TUESDAY AFTERNOON AND TUESDAY NIGHT. AN
UPPER LEVEL RIDGE COMBINED WITH LOW-LEVEL EASTERLY WINDS WILL RESULT
IN SUNNIER AND WARMER WEATHER FOR THE LATTER PART OF THE WEEK.

THIS AFTERNOON. WEBCAM IMAGERY AT ASTORIA THIS AFTERNOON ALSO SHOWED
SOME SPOTTY LIGHT DRIZZLE OCCURRING FROM TIME TO TIME. ELSEWHERE...
LOTS OF SUNSHINE GIVING WAY TO A SPLENDID LABOR DAY.

AN UPPER LEVEL TROUGH OFF THE BRITISH COLUMBIA COAST WILL DROP SOUTH
TOWARDS THE PACIFIC NW LATER TONIGHT. THE MARINE LAYER SHOULD DEEPEN
TONIGHT AND WITH INCREASED ONSHORE FLOW TONIGHT. THUS...EXPECT
MARINE CLOUDS TO PUSH FARTHER INLAND TUESDAY MORNING.  A WEAK FRONT
ASSOCIATED WITH THE UPPER LEVEL TROUGH WILL MOVE ACROSS THE NORTHERN
PART OF THE REGION TUESDAY AFTERNOON/EVENING.  THE FRONT WILL
PRODUCE SOME LIGHT RAIN ALONG THE NORTH COAST/COAST RANGE AND PART
OF THE INLAND AREA. BEST CHANCES OF MEASURABLE RAIN WILL BE IN
SOUTHWEST WA...BUT THE NORTHERN WILLAMETTE VALLEY AND ADJACENT
FOOTHILLS AND NORTH CASCADES WILL BE ON THE SOUTHERN END OF THE
FRONT AND COULD GET ALITTLE RAIN TUES EVE/NIGHT.  THERE WILL BE
ANOTHER DEEP MARINE PUSH TUESDAY NIGHT WITH A CLOUDY START TO THE
DAY ON WEDNESDAY. THE UPPER TROUGH AND INCREASE IN CLOUDS WILL KEEP
THE TEMPERATURES BELOW NORMAL TUESDAY AND WEDNESDAY.

HIGH PRESSURE WILL REBUILD OVER THE REGION THURSDAY. A FAIRLY STRONG
THERMAL TROUGH WILL ALSO BUILD NORTHWARD ALONG THE COAST. THIS WILL
RESULT IN OFFSHORE FLOW...CLEAR SKIES...AND WARMER TEMPERATURES
THE LATTER PART OF THE WORK WEEK. TW

ONSHORE WINDS WILL RETURN LATE THIS AFTERNOON BEHIND THE FRONT AND
EXPECT THE MARINE CLOUDS OFFSHORE TO PUSH CLOSER TO THE COAST. AN
UPPER LEVEL TROUGH WILL DEEPEN OFFSHORE THE B.C. COAST THIS AFTERNOON
AND DROP SOUTH TOWARDS THE PACIFIC NW TONIGHT. THE MARINE LAYER
SHOULD DEEPEN AND EXPECT MARINE CLOUDS TO PUSH FARTHER INLAND TUESDAY

ANOTHER FRONT WILL BRUSH BY TO THE NORTH TUESDAY KEEPING SKIES
GENERALLY CLOUDY NORTH OF SALEM. THE FRONT MAY GENERATE SOME LIGHT
RAIN ALONG THE NORTH COAST AND INLAND...MAINLY NORTH OF THE COLUMBIA

.SYNOPSIS...A WEAK FRONT WILL BRUSH BY THE NORTHERN FRINGES OF THE
FORECAST AREA TODAY KEEPING CLOUDY SKIES ALONG THE NORTH
COAST AND WILLAPA HILLS. OTHERWISE MOSTLY SUNNY SKIES TODAY. CLOUDY
AND COOLER WEATHER IS EXPECTED TUESDAY AND WEDNESDAY AS AN UPPER
TROUGH MOVES OVER THE AREA. THE FRONT ASSOCIATED WITH THIS TROUGH
WILL BRING SOME LIGHT RAIN TO SOUTHWEST WASHINGTON AND PARTS OF
NORTHWEST OREGON TUESDAY AFTERNOON AND TUESDAY NIGHT. AN UPPER
LEVEL RIDGE COMBINED WITH LOW-LEVEL EASTERLY WINDS WILL RESULT IN
SUNNIER AND WARMER WEATHER THURSDAY THROUGH SATURDAY. ONSHORE FLOW
WILL RETURN NEXT SUNDAY.

&&

.SHORT TERM...TODAY THROUGH THURSDAY...SATELLITE IMAGERY SHOWS SOME
CLOUDS ALONG THE NORTH COAST AND COAST RANGE THIS MORNING AND MOSTLY
SUNNY SKIES INLAND.  A VERY WEAK FRONT WILL BRUSH BY TO THE NORTH
TODAY AND MAY BRING A LITTLE LIGHT DRIZZLE TO THE NORTH COASTAL AREA
THIS MORNING. ELSEWHERE...MOSTLY SUNNY SKIES WILL PREVAIL TODAY WITH
NEAR NORMAL TEMPERATURES.

ONSHORE WINDS WILL RETURN LATE THIS AFTERNOON BEHIND THE FRONT AND
EXPECT THE MARINE CLOUDS OFFSHORE TO PUSH CLOSER TO THE COAST. AN
UPPER LEVEL TROUGH WILL DEEPEN OFFSHORE THE B.C. COAST THIS AFTERNOON
AND DROP SOUTH TOWARDS THE PACIFIC NW TONIGHT. THE MARINE LAYER
SHOULD DEEPEN AND EXPECT MARINE CLOUDS TO PUSH FARTHER INLAND TUESDAY
MORNING.

ANOTHER FRONT WILL BRUSH BY TO THE NORTH TUESDAY KEEPING SKIES
GENERALLY CLOUDY NORTH OF SALEM. THE FRONT MAY GENERATE SOME LIGHT
RAIN ALONG THE NORTH COAST AND INLAND...MAINLY NORTH OF THE COLUMBIA
RIVER TUESDAY AFTERNOON AND INTO THE OVERNIGHT HOURS. THERE WILL BE
ANOTHER DEEP MARINE PUSH TUESDAY NIGHT WITH A CLOUDY START TO THE DAY
ON WEDNESDAY. THE UPPER TROUGH AND INCREASE IN CLOUDS WILL KEEP THE
TEMPERATURES JUST BELOW NORMAL TUESDAY AND WEDNESDAY.

HIGH PRESSURE WILL REBUILD THURSDAY AND MODELS ARE CONSISTENT
DEVELOPING A THERMAL TROUGH ALONG THE COAST. THIS WILL RESULT IN
OFFSHORE FLOW...CLEAR SKIES...AND WARMER TEMPERATURES. TW/TJ

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...THURSDAY
NIGHT THROUGH SUNDAY NIGHT...AN UPPER RIDGE WILL HOLD OVER THE AREA
THROUGH SATURDAY. A THERMAL SURFACE TROUGH ALONG THE COAST WILL
CONTINUE OFFSHORE WINDS FOR DRY...SUNNY...AND SEASONALLY WARM
WEATHER THROUGH SATURDAY.  ONSHORE WINDS SHOULD RETURN LATE IN THE
WEEKEND FOR CLOUDIER AND COOLER WEATHER. TJ

.AVIATION...A WEAK DISTURBANCE WILL BE PASSING BY THROUGH WESTERN
WASHINGTON AND BRUSH EXTREME NORTHWEST OREGON TODAY FOR SOME FOR
MOSTLY VFR CIGS ALONG THE S WA AND N OREGON COAST AND INLAND
ALONG THE COLUMBIA RIVER. THE LOWEST CIGS WILL BE ALONG THE NORTH
COASTAL AREAS. THE FIRST BATCH OF CLOUDS INLAND WERE ALREADY
DISSIPATING AS THEY MOVE INTO THE CASCADES. THERE ARE MORE CLOUDS
UPSTREAM ALONG THE COAST AND EXPECT THOSE TO SPREAD INLAND THROUGH
THE AFTERNOON WITH OCCASIONAL VFR CIGS INLAND POSSIBLE MAINLY
NORTH OF KSLE. THE CENTRAL COAST NEAR KONP WILL BE ON THE EDGE OF
THESE CLOUDS FOR AWHILE...BUT MAY ALSO SEE SOME CIGS LATER TODAY
AND THIS EVENING. WITH PLENTY OF CLOUDS UPSTREAM OVER THE NE
PACIFIC...EXPECT MVFR CIGS TO PUSH ONTO THE COAST TONIGHT AND
SPREAD INLAND TO KPDX AND POSSIBLY A BIT SOUTH BY TUE MORNING.

MARINE LAYER CLOUDS, OR THE LACK THEREOF, ALONG THE COAST, AND TO
FINE TUNE THE AREAS THAT CAN EXPECT SMOKE AND HAZE FROM THE FIRES
IN SISKIYOU COUNTY. OTHERWISE, THE FORECAST LOOKS GOOD, AND THERE
IS NO NEED FOR FURTHER UPDATES.

TODAY, MAIN FOCUS OF EFFORTS WILL CENTER ON THE WARM AND DRY
CONDITIONS AND OFFSHORE FLOW EXPECTED THROUGHOUT THE WEEK. FOR
MORE INFORMATION, SEE THE PREVIOUS DISCUSSION BELOW. -BPN

.AVIATION...BASED ON THE 01/12Z TAF CYCLE...
COASTAL CONDITIONS WILL CONTINUE TO RAPIDLY IMPROVE THIS MORNING,
CLEARING THE FEW REMAINING AREAS OF MVFR TO VFR OVER THE NEXT
HOUR OR SO. VFR WILL THEN PREVAIL THROUGH THE REMAINDER OF THE
DAY. ELSEWHERE, CLEAR SKIES WILL PREVAIL FOR THE NEXT 24 HOURS

MODERATE NORTHERLY WINDS AND STEEP SEAS DEVELOPING ON MONDAY. BOTH

DISCUSSION...01/00Z NAM/GFS IN...AND SEPTEMBER HAS ARRIVED.

MOSTLY CLEAR SKIES PREVAIL ACROSS THE MEDFORD CWA THIS
MORNING...EXCEPT FOR SOME LOW CLOUDS ALONG THE COAST NORTH OF CAPE
BLANCO. FIRES IN WESTERN SISKIYOU COUNTY CONTINUE TO PRODUCE A LOT
OF SMOKE.

A BROAD LONG WAVE RIDGE CONTINUES TO BUILD INTO THE AREA FROM THE
SOUTHWEST WITH DRY NORTHWEST FLOW ALOFT. 500 MB HEIGHTS WILL RISE INTO
MONDAY THEN LEVEL OFF. THE UPPER LEVEL FLOW WILL BACK TO ZONAL
MONDAY NIGHT INTO TUESDAY AS A SHORT WAVE RIDES OVER THE TOP OF
THE RIDGE...FLATTENING IT A BIT. EXPECT A THERMAL TROUGH NEAR THE
COAST TO GRADUALLY STRENGTHEN DURING THIS INTERVAL...WITH WEAK
TO MODERATE OFFSHORE LOW LEVEL FLOW DEVELOPING TONIGHT. THIS WILL
MAKE FOR MOSTLY CLEAR SKIES AND SLIGHTLY ABOVE NORMAL TEMPERATURES...
ESPECIALLY NEAR BROOKINGS WHERE IT WILL BE QUITE WARM MONDAY.

THAT SHORT WAVE WILL DIG A TROUGH AS IT MOVES ONSHORE TUESDAY.
MOST OF THE ASSOCIATED ENERGY WILL REMAIN NORTH OF THE MEDFORD CWA
AND NO PRECIPITATION IS EXPECTED. IT WILL COOL A BIT ALONG THE
COAST AND IN THE UMPQUA BASIN AS THE THERMAL TROUGH MOVES INLAND
AND THE MARINE LAYER RETURNS. HIGHS OVER THE REST OF THE OREGON
WEST SIDE WILL REMAIN ABOUT THE SAME AS MONDAY. MEANWHILE...IT
WILL WARM UP OVER NORTHERN CALIFORNIA AND THE EAST SIDE AS THE
THERMAL TROUGH MOVES OVER THAT AREA.

THE MAIN TROUGH WILL MOVE OUT TO THE EAST WEDNESDAY...LEAVING A
WEAK RESIDUAL TROUGH OVER THE AREA WEDNESDAY NIGHT INTO THURSDAY.
AS IT DOES SO...A COLD FRONT WILL PUSH THROUGH THE AREA. INLAND
HIGHS WILL DROP AROUND 5 DEGREES WEST OF THE CASCADES...AND 5 TO
10 DEGREES EAST OF THE CASCADES. IT WILL STILL BE DRY.

NORTH TO NORTHEAST FLOW ALOFT WILL DEVELOP OVER THE AREA WEDNESDAY
INTO WEDNESDAY NIGHT. THIS PATTERN USUALLY DICTATES THAT THERE
WILL BE A LOW LEVEL OFFSHORE EVENT AND THAT WILL BE THE CASE HERE.
EXPECT CLEAR SKIES EVERYWHERE WEDNESDAY NIGHT INTO THURSDAY WITH
GUSTY WINDS AND POOR RECOVERIES OVER THE RIDGES FROM THE CASCADES
WEST. INLAND HIGHS THURSDAY WILL GENERALLY BE 1-5 DEGREES WARMER
THAN THE WEDNESDAY HIGHS...EXCEPT IN THE UMPQUA...WHERE HIGHS WILL
BE 5-10 DEGREES WARMER.

EXTENDED DISCUSSION FROM THE SUNDAY AFTERNOON AFD...FRIDAY THROUGH
SUNDAY. MODELS PUSH THE THERMAL TROUGH NORTH FROM CALIFORNIA
TOWARDS THE WILLAMETTE VALLEY. THE FORECAST AREA CAN THEREFORE
EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO CONTINUE
THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE SOME
RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER, AND
MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.

840 AM PDT MON SEP 1 2014

.UPDATE...MADE SOME ADJUSTMENTS THIS MORNING TO ACCOUNT FOR THE
MARINE LAYER CLOUDS, OR THE LACK THEREOF, ALONG THE COAST, AND TO
FINE TUNE THE AREAS THAT CAN EXPECT SMOKE AND HAZE FROM THE FIRES
IN SISKIYOU COUNTY. OTHERWISE, THE FORECAST LOOKS GOOD, AND THERE
IS NO NEED FOR FURTHER UPDATES.

TODAY, MAIN FOCUS OF EFFORTS WILL CENTER ON THE WARM AND DRY
CONDITIONS AND OFFSHORE FLOW EXPECTED THROUGHOUT THE WEEK. FOR
MORE INFORMATION, SEE THE PREVIOUS DISCUSSION BELOW. -BPN


&&

.AVIATION...BASED ON THE 01/12Z TAF CYCLE...
COASTAL CONDITIONS WILL CONTINUE TO RAPIDLY IMPROVE THIS MORNING,
CLEARING THE FEW REMAINING AREAS OF MVFR TO VFR OVER THE NEXT
HOUR OR SO. VFR WILL THEN PREVAIL THROUGH THE REMAINDER OF THE
DAY. ELSEWHERE, CLEAR SKIES WILL PREVAIL FOR THE NEXT 24 HOURS
WITH THE EXCEPTION OF REDUCED VISIBILITY DUE TO SMOKE FROM
WILDFIRES IN THE WESTERN PORTION OF SISKIYOU COUNTY. -BPN/FB

&&

.MARINE...UPDATED 830 AM PDT MON 1 SEP 2014...NORTHERLY WINDS WILL
INCREASE FROM THIS MORNING INTO WEDNESDAY AFTERNOON WITH THE
STRONGEST WINDS IN THE AREA SOUTH OF CAPE BLANCO AND BEYOND 5 NM
FROM SHORE. A THERMAL TROUGH WILL PERSIST ALONG THE COAST WITH
MODERATE NORTHERLY WINDS AND STEEP SEAS DEVELOPING ON MONDAY. BOTH
WINDS AND SEAS WILL INCREASE TUESDAY THROUGH THURSDAY AND COULD
REACH GALE FORCE WINDS AND VERY STEEP SEAS AS THE THERMAL TROUGH
STRENGTHENS. /FB

.PREV DISCUSSION... /ISSUED 100 AM PDT MON SEP 1 2014/

DISCUSSION...01/00Z NAM/GFS IN...AND SEPTEMBER HAS ARRIVED.

MOSTLY CLEAR SKIES PREVAIL ACROSS THE MEDFORD CWA THIS
MORNING...EXCEPT FOR SOME LOW CLOUDS ALONG THE COAST NORTH OF CAPE
BLANCO. FIRES IN WESTERN SISKIYOU COUNTY CONTINUE TO PRODUCE A LOT
OF SMOKE.

A BROAD LONG WAVE RIDGE CONTINUES TO BUILD INTO THE AREA FROM THE
SOUTHWEST WITH DRY NORTHWEST FLOW ALOFT. 500 MB HEIGHTS WILL RISE INTO
MONDAY THEN LEVEL OFF. THE UPPER LEVEL FLOW WILL BACK TO ZONAL
MONDAY NIGHT INTO TUESDAY AS A SHORT WAVE RIDES OVER THE TOP OF
THE RIDGE...FLATTENING IT A BIT. EXPECT A THERMAL TROUGH NEAR THE
COAST TO GRADUALLY STRENGTHEN DURING THIS INTERVAL...WITH WEAK
TO MODERATE OFFSHORE LOW LEVEL FLOW DEVELOPING TONIGHT. THIS WILL
MAKE FOR MOSTLY CLEAR SKIES AND SLIGHTLY ABOVE NORMAL TEMPERATURES...
ESPECIALLY NEAR BROOKINGS WHERE IT WILL BE QUITE WARM MONDAY.

THAT SHORT WAVE WILL DIG A TROUGH AS IT MOVES ONSHORE TUESDAY.
MOST OF THE ASSOCIATED ENERGY WILL REMAIN NORTH OF THE MEDFORD CWA
AND NO PRECIPITATION IS EXPECTED. IT WILL COOL A BIT ALONG THE
COAST AND IN THE UMPQUA BASIN AS THE THERMAL TROUGH MOVES INLAND
AND THE MARINE LAYER RETURNS. HIGHS OVER THE REST OF THE OREGON
WEST SIDE WILL REMAIN ABOUT THE SAME AS MONDAY. MEANWHILE...IT
WILL WARM UP OVER NORTHERN CALIFORNIA AND THE EAST SIDE AS THE
THERMAL TROUGH MOVES OVER THAT AREA.

THE MAIN TROUGH WILL MOVE OUT TO THE EAST WEDNESDAY...LEAVING A
WEAK RESIDUAL TROUGH OVER THE AREA WEDNESDAY NIGHT INTO THURSDAY.
AS IT DOES SO...A COLD FRONT WILL PUSH THROUGH THE AREA. INLAND
HIGHS WILL DROP AROUND 5 DEGREES WEST OF THE CASCADES...AND 5 TO
10 DEGREES EAST OF THE CASCADES. IT WILL STILL BE DRY.

NORTH TO NORTHEAST FLOW ALOFT WILL DEVELOP OVER THE AREA WEDNESDAY
INTO WEDNESDAY NIGHT. THIS PATTERN USUALLY DICTATES THAT THERE
WILL BE A LOW LEVEL OFFSHORE EVENT AND THAT WILL BE THE CASE HERE.
EXPECT CLEAR SKIES EVERYWHERE WEDNESDAY NIGHT INTO THURSDAY WITH
GUSTY WINDS AND POOR RECOVERIES OVER THE RIDGES FROM THE CASCADES
WEST. INLAND HIGHS THURSDAY WILL GENERALLY BE 1-5 DEGREES WARMER
THAN THE WEDNESDAY HIGHS...EXCEPT IN THE UMPQUA...WHERE HIGHS WILL
BE 5-10 DEGREES WARMER.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
100 AM PDT MON SEP 1 2014

.DISCUSSION...01/00Z NAM/GFS IN...AND SEPTEMBER HAS ARRIVED.

MOSTLY CLEAR SKIES PREVAIL ACROSS THE MEDFORD CWA THIS
MORNING...EXCEPT FOR SOME LOW CLOUDS ALONG THE COAST NORTH OF CAPE
BLANCO. FIRES IN WESTERN SISKIYOU COUNTY CONTINUE TO PRODUCE A LOT
OF SMOKE.

A BROAD LONG WAVE RIDGE CONTINUES TO BUILD INTO THE AREA FROM THE
SOUTHWEST WITH DRY NORTHWEST FLOW ALOFT. 500 MB HEIGHTS WILL RISE INTO
MONDAY THEN LEVEL OFF. THE UPPER LEVEL FLOW WILL BACK TO ZONAL
MONDAY NIGHT INTO TUESDAY AS A SHORT WAVE RIDES OVER THE TOP OF
THE RIDGE...FLATTENING IT A BIT. EXPECT A THERMAL TROUGH NEAR THE
COAST TO GRADUALLY STRENGTHEN DURING THIS INTERVAL...WITH WEAK
TO MODERATE OFFSHORE LOW LEVEL FLOW DEVELOPING TONIGHT. THIS WILL
MAKE FOR MOSTLY CLEAR SKIES AND SLIGHTLY ABOVE NORMAL TEMPERATURES...
ESPECIALLY NEAR BROOKINGS WHERE IT WILL BE QUITE WARM MONDAY.

THAT SHORT WAVE WILL DIG A TROUGH AS IT MOVES ONSHORE TUESDAY.
MOST OF THE ASSOCIATED ENERGY WILL REMAIN NORTH OF THE MEDFORD CWA
AND NO PRECIPITATION IS EXPECTED. IT WILL COOL A BIT ALONG THE
COAST AND IN THE UMPQUA BASIN AS THE THERMAL TROUGH MOVES INLAND
AND THE MARINE LAYER RETURNS. HIGHS OVER THE REST OF THE OREGON
WEST SIDE WILL REMAIN ABOUT THE SAME AS MONDAY. MEANWHILE...IT
WILL WARM UP OVER NORTHERN CALIFORNIA AND THE EAST SIDE AS THE
THERMAL TROUGH MOVES OVER THAT AREA.

THE MAIN TROUGH WILL MOVE OUT TO THE EAST WEDNESDAY...LEAVING A
WEAK RESIDUAL TROUGH OVER THE AREA WEDNESDAY NIGHT INTO THURSDAY.
AS IT DOES SO...A COLD FRONT WILL PUSH THROUGH THE AREA. INLAND
HIGHS WILL DROP AROUND 5 DEGREES WEST OF THE CASCADES...AND 5 TO
10 DEGREES EAST OF THE CASCADES. IT WILL STILL BE DRY.

NORTH TO NORTHEAST FLOW ALOFT WILL DEVELOP OVER THE AREA WEDNESDAY
INTO WEDNESDAY NIGHT. THIS PATTERN USUALLY DICTATES THAT THERE
WILL BE A LOW LEVEL OFFSHORE EVENT AND THAT WILL BE THE CASE HERE.
EXPECT CLEAR SKIES EVERYWHERE WEDNESDAY NIGHT INTO THURSDAY WITH
GUSTY WINDS AND POOR RECOVERIES OVER THE RIDGES FROM THE CASCADES
WEST. INLAND HIGHS THURSDAY WILL GENERALLY BE 1-5 DEGREES WARMER
THAN THE WEDNESDAY HIGHS...EXCEPT IN THE UMPQUA...WHERE HIGHS WILL
BE 5-10 DEGREES WARMER.

EXTENDED DISCUSSION FROM THE SUNDAY AFTERNOON AFD...FRIDAY THROUGH
SUNDAY. MODELS PUSH THE THERMAL TROUGH NORTH FROM CALIFORNIA
TOWARDS THE WILLAMETTE VALLEY. THE FORECAST AREA CAN THEREFORE
EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO CONTINUE
THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE SOME
RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER, AND
MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.
UNCERTAINTY IS VERY HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE
FORECAST AT THIS TIME.

&&

.AVIATION...BASED ON THE 01/06Z TAF CYCLE...MVFR CIGS HAVE
RETURNED TO THE COAST FROM CAPE BLANCO NORTHWARD, INCLUDING NORTH
BEND/KOTH. THIS COASTAL STRATUS WILL LOWER OVERNIGHT INTO THE
EARLY MORNING AND SPREAD INTO THE COQUILLE VALLEY WITH AREAS OF
IFR CIGS AND VSBYS DEVELOPING. COASTAL CONDITIONS WILL IMPROVE
AFTER 15Z MONDAY MORNING. NORTHERLY LOW LEVEL WINDS ALONG THE
COAST WILL INCREASE DURING THE DAY.

ELSEWHERE, CLEAR SKIES WILL PREVAIL FOR THE NEXT 24 HOURS WITH THE
EXCEPTION OF REDUCED VISIBILITY IN SISKIYOU COUNTY DUE TO SMOKE
FROM WILDFIRES IN THE WESTERN PORTION OF SISKIYOU COUNTY.

RIDGING SHOULD BRING WARMER AND DRY CONDITIONS FOR MON...BUT ANOTHER

.SHORT TERM...TONIGHT THROUGH WEDNESDAY.
THE LATEST OBSERVATIONS AND SATELLITE IMAGERY SHOW CLOUDS SCATTERING
ACROSS THE REGION THIS EVENING. THERE WERE A FEW SPRINKLES AROUND THE
REGION TODAY...BUT THE ATMOSPHERE IS STABILIZING NOW AND DOPPLER
RADAR IS SHOWING NOTHING OVER THE PAST HOUR OR TWO. SO DECIDED TO
REMOVE ANY MENTION OF SHOWERS FROM THE FCST FOR THE REST OF THE
NIGHT. MARINE CLOUDS SHOULD REFORM ALONG THE COAST OVER THE NEXT FEW
HOURS...THEN PUSH PARTIALLY INLAND OVERNIGHT. 500 MB HEIGHTS ARE
BEGINNING TO RISE AND THE ONSHORE FLOW IS NOT VERY STRONG...SO DO NOT
EXPECT A VERY IMPRESSIVE INLAND PUSH. STRATUS WILL PROBABLY STRUGGLE
TO MAKE IT MUCH BEYOND KELSO. ANOTHER CLOUD DECK MAY FORM ALONG THE
CASCADE FOOTHILLS AND BACK BUILD TOWARD THE WILLAMETTE VALLEY.

THE NW FLOW REMAINS OVER PAC N TO START THE UPCOMING WEEK...WITH
ONSHORE FLOW KEEPING A MIX OF SUN AND CLOUDS CONTINUING ACROSS THE
REGION. THE STORM TRACK WILL KEEP THE EMBEDDED DISTURBANCES TO THE N
ACROSS BRITISH COLUMBIA AND WASHINGTON. TOMORROW LOOKS DRY AS THREAT
OF SHOWERS ASSOCIATED WITH A DISSIPATING FRONT LOOKS TO REMAIN TO THE
NORTH OF OUR FORECAST AREA. TEMPERATURES SHOULD INCREASE A BIT BACK
TOWARD SEASONAL NORMALS IN RESPONSE TO THE INCREASING 500 MB HEIGHTS.


THE NEXT FRONT WILL ARRIVE LATER TUE...BRINGING INCREASING CLOUDS
AND A DECENT CHANCE OF SHOWERS OR BRIEF LIGHT RAIN TO THE REGION.
WILL KEEP WITH CHANCE OF SHOWERS N OF A TILLAMOOK TO MT HOOD LINE AND
KEEP IT DRY TO THE S. LIKE MON...BULK OF PRECIP REMAINS ACROSS
WESTERN WASHINGTON AND BRITISH COLUMBIA.

THEN WILL CHANGE OVERALL WEATHER PATTERN...AS HIGH PRES BEGINS TO

CLOUDS. PYLE/ROCKEY

.LONG TERM...AN UPPER LEVEL RIDGE NOSES INTO WESTERN CANADA AND
NORTHERN WASHINGTON THURSDAY...BUT A LOW OFF OF CALIFORNIA WILL
MAINTAIN LOWER PRESSURE OVER NW OREGON. HIGH PRESSURE TO THE NORTH
AND EAST...WITH LOW PRESSURE TO THE SOUTH AND SOUTHEAST WILL RESULT
IN OFFSHORE WINDS ACROSS THE PORTLAND FORECAST AREA. EXPECT AN
INCREASE IN SUNSHINE AND AFTERNOON TEMPERATURES THURSDAY THROUGH
NEXT SATURDAY. BEYOND THAT...THE MODELS ARE STARTING TO HINT AT
ANOTHER SYSTEM PUSHING INTO THE PACIFIC NORTHWEST LATE NEXT SUNDAY.
WITH THIS SYSTEM WE WILL LIKELY SEE A SLIGHT DECREASE IN AFTERNOON
TEMPERATURES. A SLIGHT CHANCE OF SHOWERS ARE ALSO NOT OUT OF THE

931 PM PDT SUN AUG 31 2014

.SYNOPSIS...CLOUDS ARE CLEARING ACROSS MUCH OF THE REGION THIS
EVENING...BUT THEY ARE EXPECTED TO REFORM ALONG THE COAST OVER THE
NEXT FEW HOURS AND THEN PUSH PARTIALLY INLAND OVERNIGHT. WEAK UPPER
RIDGING SHOULD BRING WARMER AND DRY CONDITIONS FOR MON...BUT ANOTHER
FRONT WILL PUSH ACROSS THE REGION LATER TUE...BRINGING ANOTHER CHANCE
OF SHOWERS. THEN WARMER AND DRY WEATHER IS FORECAST FOR REST OF THE
WEEK UNDER OFFSHORE FLOW.
&&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY.
THE LATEST OBSERVATIONS AND SATELLITE IMAGERY SHOW CLOUDS SCATTERING
ACROSS THE REGION THIS EVENING. THERE WERE A FEW SPRINKLES AROUND THE
REGION TODAY...BUT THE ATMOSPHERE IS STABILIZING NOW AND DOPPLER
RADAR IS SHOWING NOTHING OVER THE PAST HOUR OR TWO. SO DECIDED TO
REMOVE ANY MENTION OF SHOWERS FROM THE FCST FOR THE REST OF THE
NIGHT. MARINE CLOUDS SHOULD REFORM ALONG THE COAST OVER THE NEXT FEW
HOURS...THEN PUSH PARTIALLY INLAND OVERNIGHT. 500 MB HEIGHTS ARE
BEGINNING TO RISE AND THE ONSHORE FLOW IS NOT VERY STRONG...SO DO NOT
EXPECT A VERY IMPRESSIVE INLAND PUSH. STRATUS WILL PROBABLY STRUGGLE
TO MAKE IT MUCH BEYOND KELSO. ANOTHER CLOUD DECK MAY FORM ALONG THE
CASCADE FOOTHILLS AND BACK BUILD TOWARD THE WILLAMETTE VALLEY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
858 PM PDT SUN AUG 31 2014

.DISCUSSION...AN UPDATE TO THE FORECAST IS NOT NECESSARY. THE NEXT
WEEK WILL BE NOTABLY WARM AND DRY WITH A PERSISTENT THERMAL TROUGH
NEAR THE COAST. THIS WILL RESULT IN A WIDENING DIURNAL RANGE OF
TEMPERATURES WITH MORNING LOWS DOWN INTO THE 30S FOR MANY OF THE
EAST SIDE VALLEYS THROUGH THE WEEK WHILE HIGH TEMPERATURES ACROSS
THE AREA WILL BE ABOVE NORMAL...EXCEPT FOR SLIGHT POST-FRONTAL
COOLING FOR WEDNESDAY.

THERE WILL BE VERY LITTLE CLOUD COVER EXCEPT FOR LATE NIGHT LOW
CLOUDS AT THE COAST NORTH OF CAPE BLANCO. HIGH TEMPERATURES ON
LABOR DAY WILL BE GENERALLY 5 TO 8 DEGREES WARMER THAN THEY WERE
TODAY. A DRY COLD FRONT LATE IN THE DAY ON TUESDAY WILL KEEP WEST
SIDE HIGHS ON TUESDAY AROUND THE SAME READINGS FROM MONDAY WHILE
THERE ARE A FEW DEGREES OF WARMING FOR THE EAST SIDE. THIS FRONT
WILL BRING BREEZY WEST TO NORTHWEST WINDS INLAND TUESDAY AFTERNOON
AND EVENING WITH THE STRONGEST WINDS ON THE EAST SIDE...EXCEPT FOR
STRONGER NORTH WINDS AT THE COAST.

&&

.AVIATION...BASED ON THE 01/00Z TAF CYCLE...
ALTHOUGH MVFR/IFR CIGS HAVE CLEARED TO VFR ALONG THE COAST, THEY
WILL LIKELY RETURN THIS EVENING. ELSEWHERE, VFR CONDITIONS WILL
PREVAIL FOR THE NEXT 24 HOURS. VIS HAVE BEEN REDUCED AT TIME SOUTH
AND SOUTHEAST OF THE FIRES. HOWEVER THERE ARE SIGNS THE SMOKE IS
CHANGING DIRECTION AND IS NOW STARTING TO MOVE EAST AS EVIDENCED BY
THE VISIBLE SATELLITE IMAGE. THEREFORE REDUCTION IN VIS DUE TO SMOKE
COULD AFFECT EASTERN SISKIYOU AND MODOC COUNTIES. -PETRUCELLI

&&

.MARINE...UPDATED 300 PM PDT SUN 31 AUG 2014...WINDS AT BUOY 27 HAVE
INCREASED THE LAST FEW HOURS AND COULD BRIEFLY HIT SMALL CRAFT FOR A
FEW HOURS THROUGH EARLY THIS EVENING. SEAS HAVE NOT COME UP AS MUCH
YET, BUT THEY WILL WITH SMALL CRAFT FOR SEAS EXPECTED TO ONLY AFFECT
A SMALL PORTION OF PZZ376. MODELS REMAIN CONSISTENT WITH A THERMAL
TROUGH DEVELOPING MONDAY MORNING AND STRENGTHENING MONDAY AFTERNOON.
THIS PATTERN IS LIKELY TO PERSIST FOR MOST OF NEXT WEEK WITH
MODERATE TO STRONG NORTHERLY WINDS AND STEEP TO VERY STEEP WIND WAVE
DOMINATED SEAS. WINDS THROUGH THE WEEK ARE EXPECTED TO BE STRONGEST
SOUTH OF GOLD BEACH AND COULD APPROACH GALE FORCE WEDNESDAY
AFTERNOON AND EVENING. -PETRUCELLI

&&

.PREV DISCUSSION... /ISSUED 250 PM PDT SUN AUG 31 2014/

DISCUSSION...THE PATTERN THROUGH THE NEXT WEEK WILL BE BASED
UPON TWO FEATURES. THE FIRST IS THE THERMAL TROUGH, WHICH IS
EXPECTED TO BE PRESENT THROUGH THE ENTIRE WEEK, AND THE SECOND
WILL BE A LONG LIVED BUT BROAD UPPER LEVEL TROUGH EXPECTED TO
ENTER THE AREA BY MIDWEEK. UNFORTUNATELY, THERE APPEARS TO BE NO
GOOD CHANCE OF RAIN IN THE FORECAST, WITH THE BEST POSSIBLE, YET
STILL VERY SLIGHT, CHANCE ARRIVING LATE IN THE TERM. CONFIDENCE IS
HIGH THAT WARM AND DRY CONDITIONS WILL CONTINUE FOR AT LEAST THE
NEXT SEVEN DAYS.

UNTIL THE MID LEVEL TROUGH ARRIVES, THE THERMAL TROUGH TO OUR SOUTH
WILL GRADUALLY STRENGTHEN, THEREBY CREATING A GENERAL OFFSHORE FLOW
WITH MOSTLY CLEAR SKIES, WARMING TEMPERATURES AND DRY CONDITIONS.
THIS IS ESPECIALLY TRUE FOR WEST SIDE AND CASCADE RIDGE LINES, WHERE
TEMPERATURES WILL REMAIN WARM AND HUMIDITY WILL REMAIN LOW THROUGH
THE NIGHT. WHEN THE UPPER LEVEL TROUGH ARRIVES TUESDAY NIGHT INTO
WEDNESDAY, AN ASSOCIATED WEAK DRY COLD FRONT IS EXPECTED TO WASH OUT
AS IT REACHES THE SOUTH END OF THE WILLAMETTE VALLEY. BUT OTHER THAN
PRODUCING SOME CLOUDINESS WEDNESDAY, THE FRONT WILL ONLY ACT TO
INCREASE THE TEMPERATURE DIFFERENCE BETWEEN THE THERMAL TOUGH TO THE
SOUTH AND THE COOLER AIR TO THE NORTH. THE RESULT WILL BE INCREASED
OFFSHORE WINDS THROUGH THURSDAY AND VERY DRY AIR OVER THE AREA.

FOR THE REST OF THE WEEK, MODELS PUSH THE THERMAL TROUGH NORTH FROM
CALIFORNIA TOWARDS THE WILLAMETTE VALLEY. THE FORECAST AREA CAN
THEREFORE EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO
CONTINUE THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE
SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER,
AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.
UNCERTAINTY IS VERY HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE
FORECAST AT THIS TIME.


FIRE WEATHER...THE BRIEF TASTE OF MOISTURE THAT WE HAD THIS MORNING
IS FLYING AWAY QUICKLY AS SUBSIDENCE BLOWS IT FROM THE TIPS OF OUR
TONGUES. OFFSHORE FLOW DEVELOPS BY LATE TONIGHT TO FURTHER DRY THINGS
OUT. ON TUESDAY THE THERMAL TROUGH MOVES INLAND WITH INCREASED UP
VALLEY FLOW. THE MODELS INDICATE A HAINES OF 5 FOR TUESDAY...AND
PAST EXPERIENCE HAS SHOWN THAT EXISTING FIRES IN THIS SITUATION
BEHAVE AS IF THERE WAS A HAINES OF 6. HOWEVER...THERE IS SOME
DISPUTE AS TO WHETHER THE TROUGH WILL MOVE INLAND ON TUESDAY OR
WEDNESDAY. WILL WAIT TO COORDINATE WITH THE FIRES IN THE CASCADES
ABOUT THIS BEFORE POSSIBLE WARNING ISSUANCE. DRYING..ESPECIALLY AT
THE RIDGE LEVEL...CONTINUES INTO THURSDAY WITH THE NAM INDICATING
850 MB DEWPOINTS BELOW ZERO C...AND LOWER THAN -15 C OVER MUCH OF
THE WEST SIDE BY THURSDAY MORNING. THE OFFSHORE FINALLY WEAKENS
SUNDAY...BUT REMAINS OFFSHORE ON BOTH THE GFS AND ECMWF...AND HAVE

THEREFORE EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO
CONTINUE THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE
SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER,
AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.
UNCERTAINTY IS VERY HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE
FORECAST AT THIS TIME.


FIRE WEATHER...THE BRIEF TASTE OF MOISTURE THAT WE HAD THIS MORNING
IS FLYING AWAY QUICKLY AS SUBSIDENCE BLOWS IT FROM THE TIPS OF OUR
TONGUES. OFFSHORE FLOW DEVELOPS BY LATE TONIGHT TO FURTHER DRY THINGS
OUT. ON TUESDAY THE THERMAL TROUGH MOVES INLAND WITH INCREASED UP
VALLEY FLOW. THE MODELS INDICATE A HAINES OF 5 FOR TUESDAY...AND
PAST EXPERIENCE HAS SHOWN THAT EXISTING FIRES IN THIS SITUATION
BEHAVE AS IF THERE WAS A HAINES OF 6. HOWEVER...THERE IS SOME
DISPUTE AS TO WHETHER THE TROUGH WILL MOVE INLAND ON TUESDAY OR
WEDNESDAY. WILL WAIT TO COORDINATE WITH THE FIRES IN THE CASCADES
ABOUT THIS BEFORE POSSIBLE WARNING ISSUANCE. DRYING..ESPECIALLY AT
THE RIDGE LEVEL...CONTINUES INTO THURSDAY WITH THE NAM INDICATING
850 MB DEWPOINTS BELOW ZERO C...AND LOWER THAN -15 C OVER MUCH OF
THE WEST SIDE BY THURSDAY MORNING. THE OFFSHORE FINALLY WEAKENS
SUNDAY...BUT REMAINS OFFSHORE ON BOTH THE GFS AND ECMWF...AND HAVE
KEPT RH`S LOW PRETTY MUCH TO THE COAST THROUGH THE EXTENDED. -SVEN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
250 PM PDT SUN AUG 31 2014

.DISCUSSION...THE PATTERN THROUGH THE NEXT WEEK WILL BE BASED
UPON TWO FEATURES. THE FIRST IS THE THERMAL TROUGH, WHICH IS
EXPECTED TO BE PRESENT THROUGH THE ENTIRE WEEK, AND THE SECOND
WILL BE A LONG LIVED BUT BROAD UPPER LEVEL TROUGH EXPECTED TO
ENTER THE AREA BY MIDWEEK. UNFORTUNATELY, THERE APPEARS TO BE NO
GOOD CHANCE OF RAIN IN THE FORECAST, WITH THE BEST POSSIBLE, YET
STILL VERY SLIGHT, CHANCE ARRIVING LATE IN THE TERM. CONFIDENCE IS
HIGH THAT WARM AND DRY CONDITIONS WILL CONTINUE FOR AT LEAST THE
NEXT SEVEN DAYS.

UNTIL THE MID LEVEL TROUGH ARRIVES, THE THERMAL TROUGH TO OUR SOUTH
WILL GRADUALLY STRENGTHEN, THEREBY CREATING A GENERAL OFFSHORE FLOW
WITH MOSTLY CLEAR SKIES, WARMING TEMPERATURES AND DRY CONDITIONS.
THIS IS ESPECIALLY TRUE FOR WEST SIDE AND CASCADE RIDGE LINES, WHERE
TEMPERATURES WILL REMAIN WARM AND HUMIDITY WILL REMAIN LOW THROUGH
THE NIGHT. WHEN THE UPPER LEVEL TROUGH ARRIVES TUESDAY NIGHT INTO
WEDNESDAY, AN ASSOCIATED WEAK DRY COLD FRONT IS EXPECTED TO WASH OUT
AS IT REACHES THE SOUTH END OF THE WILLAMETTE VALLEY. BUT OTHER THAN
PRODUCING SOME CLOUDINESS WEDNESDAY, THE FRONT WILL ONLY ACT TO
INCREASE THE TEMPERATURE DIFFERENCE BETWEEN THE THERMAL TOUGH TO THE
SOUTH AND THE COOLER AIR TO THE NORTH. THE RESULT WILL BE INCREASED
OFFSHORE WINDS THROUGH THURSDAY AND VERY DRY AIR OVER THE AREA.

FOR THE REST OF THE WEEK, MODELS PUSH THE THERMAL TROUGH NORTH FROM
CALIFORNIA TOWARDS THE WILLAMETTE VALLEY. THE FORECAST AREA CAN
THEREFORE EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO
CONTINUE THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE
SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER,
AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.
UNCERTAINTY IS VERY HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE
FORECAST AT THIS TIME.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
250 PM PDT SUN AUG 31 2014

.DISCUSSION...THE PATTERN THROUGH THE NEXT WEEK WILL BE BASED
UPON TWO FEATURES. THE FIRST IS THE THERMAL TROUGH, WHICH IS
EXPECTED TO BE PRESENT THROUGH THE ENTIRE WEEK, AND THE SECOND
WILL BE A LONG LIVED BUT BROAD UPPER LEVEL TROUGH EXPECTED TO
ENTER THE AREA BY MIDWEEK. UNFORTUNATELY, THERE APPEARS TO BE NO
GOOD CHANCE OF RAIN IN THE FORECAST, WITH THE BEST POSSIBLE, YET
STILL VERY SLIGHT, CHANCE ARRIVING LATE IN THE TERM. CONFIDENCE IS
HIGH THAT WARM AND DRY CONDITIONS WILL CONTINUE FOR AT LEAST THE
NEXT SEVEN DAYS.

UNTIL THE MID LEVEL TROUGH ARRIVES, THE THERMAL TROUGH TO OUR SOUTH
WILL GRADUALLY STRENGTHEN, THEREBY CREATING A GENERAL OFFSHORE FLOW
WITH MOSTLY CLEAR SKIES, WARMING TEMPERATURES AND DRY CONDITIONS.
THIS IS ESPECIALLY TRUE FOR WEST SIDE AND CASCADE RIDGE LINES, WHERE
TEMPERATURES WILL REMAIN WARM AND HUMIDITY WILL REMAIN LOW THROUGH
THE NIGHT. WHEN THE UPPER LEVEL TROUGH ARRIVES TUESDAY NIGHT INTO
WEDNESDAY, AN ASSOCIATED WEAK DRY COLD FRONT IS EXPECTED TO WASH OUT
AS IT REACHES THE SOUTH END OF THE WILLAMETTE VALLEY. BUT OTHER THAN
PRODUCING SOME CLOUDINESS WEDNESDAY, THE FRONT WILL ONLY ACT TO
INCREASE THE TEMPERATURE DIFFERENCE BETWEEN THE THERMAL TOUGH TO THE
SOUTH AND THE COOLER AIR TO THE NORTH. THE RESULT WILL BE INCREASED
OFFSHORE WINDS THROUGH THURSDAY AND VERY DRY AIR OVER THE AREA.

FOR THE REST OF THE WEEK, MODELS PUSH THE THERMAL TROUGH NORTH FROM
CALIFORNIA TOWARDS THE WILLAMETTE VALLEY. THE FORECAST AREA CAN
THEREFORE EXPECT CONTINUING WARM TEMPERATURES AND LOW HUMIDITY TO
CONTINUE THROUGH THE REMAINDER OF THE FORECAST TERM. THERE MAY BE
SOME RELIEF BY EARLY NEXT WEEK, AS MODELS ARE PRODUCING A STRONGER,
AND MORE IMPORTANTLY, WETTER SYSTEM ENTERING THE PACIFIC NORTHWEST.
UNCERTAINTY IS VERY HIGH, SO HAVE LEFT MENTION OF POPS OUT OF THE
FORECAST AT THIS TIME.

.SHORT TERM...TONIGHT THROUGH TUESDAY...RESIDUAL MOISTURE
RESIDING IN A W-NW FLOW WITH DAYTIME HEATING PROMOTED SCATTERED
CUMULUS CLOUDS ACROSS THE NORTHERN PORTIONS OF SOUTHEAST OREGON
AND SOUTHWEST IDAHO THIS AFTERNOON. THE CLOUDS HAVE SHOWN LITTLE
VERTICAL EXTENT AS THE AIR MASS HAS STABILIZED SINCE
YESTERDAY...THUS WE ARE NOT EXPECTING ANY SHOWERS WITH THE CLOUDS.
THE CLOUDS WILL DIMINISH OVERNIGHT WITH CLEAR SKIES EXPECTED LATE.
GUSTY W-NW WINDS WILL ALSO DIMINISH THIS EVENING. THE COMBINATION
OF CLEARING SKIES AND LIGHT WINDS WILL BRING A COOL START TO LABOR
DAY. LABOR DAY THROUGH TUESDAY...FLOW ALOFT WILL TURN W-SWLY AHEAD
OF AN UPPER TROUGH AND COLD FRONT WHICH WILL MOVE INTO THE PACIFIC
NORTHWEST. THIS WILL RESULT IN A WARMING TREND...ALONG WITH MOSTLY
CLEAR SKIES AND LIGHT WINDS. HIGHS ON TUESDAY WILL BE NEAR TO
SLIGHTLY ABOVE NORMAL.

.LONG TERM...TUESDAY NIGHT THROUGH FRIDAY...FAIRLY GOOD AGREEMENT
IN MODELS THAT A DRY COLD FRONT WILL PUSH THROUGH THE AREA TUESDAY
NIGHT. THIS IN RESPONSE TO UPPER LEVEL TROUGH THAT MOVES FROM NEAR
VANCOUVER ISLAND ON TUESDAY NIGHT...TO NORTH DAKOTA BY THURSDAY
MORNING. TROUGH LOOKS FAR ENOUGH AWAY THAT MOISTURE WILL BE NORTH
OF THE AREA...AND WE HAVE REMOVED MENTION OF PRECIP DURING THE
PERIOD. MOST NOTICEABLE WILL BE TEMPERATURES ABOUT 10 DEGREES
BELOW NORMAL ON WEDNESDAY BEHIND THE FRONT. REMNANTS OF THE TROUGH
JUST LINGER OVER THE AREA THROUGH FRIDAY...WITH A PIECE DEEPENING
OFF THE CALIFORNIA COAST...WHICH MEANS THAT TEMPERATURES WILL BE
SLOW TO RECOVER...AND WILL STILL BE ABOUT 5 DEGREES BELOW NORMAL
BY FRIDAY.

FRIDAY NIGHT THROUGH SUNDAY...DRY NORTHWESTERLY WINDS WILL BE THE
PREDOMINANT FLOW IN OUR REGION AS THE UPPER LEVEL TROUGH MOVES TO

.PREV DISC... /ISSUED 415 AM PDT SUN AUG 31 2014/

SHORT TERM...TODAY THROUGH TUESDAY...A NORTHWEST FLOW HAS DEVELOPED
OVER THE REGION WITH COOLER AND MORE STABLE AIR MOVING IN. THIS WILL
RESULT IN MOSTLY DRY AND COOL CONDITIONS FOR THE NEXT COUPLE OF
DAYS. THERE ARE WEAK WAVES IN THE FLOW. THE NEXT WAVE TO AFFECT THE
CWA WILL MOVE SOUTHEAST AND ACROSS THE CWA TONIGHT AND MONDAY. THERE
WILL BE VERY LIMITED MOISTURE WITH THIS WAVE SO CAN EXPECT MAINLY
JUST CLOUDS. THE ONLY CHANCE FOR SHOWERS WILL BE ALONG THE EAST
SLOPES OF THE SOUTHERN AND CENTRAL WASHINGTON CASCADES TODAY AND
TONIGHT. AFTER THAT IT WILL BECOME DRY ACROSS THE ENTIRE CWA. A
SLIGHT RIDGE WILL BUILD IN THE NORTHWEST FLOW ON MONDAY PROVIDING
DRIER AND STABLE CONDITIONS. THEN ON TUESDAY AN UPPER TROUGH WILL
SAG SOUTHWARD ALONG THE COAST CAUSING THE FLOW OVER THE CWA TO
GRADUALLY BECOME MORE WESTERLY...AND EVENTUALLY SOUTHWEST GOING INTO
THE EXTENDED PERIOD. THE AMOUNT OF MOISTURE WITH THIS COASTAL TROUGH
WILL BE VERY LIMITED AND THEREFORE CAN EXPECT ONLY A FEW SHOWERS
ALONG THE WASHINGTON CASCADE EAST SLOPES ON TUESDAY. TEMPERATURES
WILL BE COOLER THAN NORMAL AND MAINLY IN THE 70S LOWER ELEVATIONS
TODAY THROUGH TUESDAY. IT WILL ALSO BECOME BREEZY AT TIMES IN THE
AFTERNOONS AND EVENINGS...MAINLY IN THE EASTERN COLUMBIA RIVER GORGE
AND THE KITTITAS VALLEY. 88

LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...AN UPPER LEVEL TROUGH
WILL MOVE THROUGH WASHINGTON AND OREGON TUESDAY NIGHT. THE MAIN LIFT
AND MOISTURE WILL REMAIN IN CANADA SO VERY LITTLE PRECIPITATION IS
EXPECTED IN THE CWA. THIS TROUGH WILL SPLIT WITH THE NORTHERN
PORTION CONTINUING EASTWARD AND THE SOUTHERN PORTION DROPPING SOUTH
OVER NORTHERN CALIFORNIA WEDNESDAY AND THURSDAY. THIS WILL PLACE
WASHINGTON AND OREGON IN A DRY NORTHERLY FLOW WITH A RIDGE
AMPLIFYING IN THE EASTERN PACIFIC. THE REST OF THE EXTENDED PERIOD
WILL SEE MOSTLY SUNNY SKIES AND GRADUAL WARMING TEMPERATURES.

OF SALEM. HIGHS ALONG THE COAST STAY IN THE 60S.

THE NEXT FRONT WILL ARRIVE LATER TUE...BRINGING INCREASING CLOUDS
AND A DECENT CHANCE OF SHOWERS OR BRIEF LIGHT RAIN TO THE REGION.
WILL LOOK AT MODELS...BUT MAY HAVE TO WAIT UNTIL NEXT SHIFT OR TWO
FOR MORE CONSISTENT TRENDS DEVELOP THAT WOULD LEAD TO INCREASING
PRECIP PROBABILITY FOR LATE TUE/TUE NIGHT. MODEL CONSISTENCY HAS NOT
BEEN TOO GOOD...SO CONFIDENCE IS NOT GREAT.            ROCKEY.

.LONG TERM...WEDNESDAY NIGHT THROUGH SATURDAY...THE UPPER TROUGH
MOVES INLAND WEDNESDAY NIGHT. AN UPPER LEVEL RIDGE NOSES INTO WESTERN
CANADA AND NORTHERN WASHINGTON THURSDAY...BUT A LOW OFF OF CALIFORNIA
WILL MAINTAIN LOWER PRESSURE OVER NW OREGON. HIGH PRESSURE TO THE
NORTH AND EAST...WITH LOW PRESSURE TO THE SOUTH AND SOUTHEAST WILL
RESULT IN OFFSHORE WINDS ACROSS THE PORTLAND FORECAST AREA. EXPECT
AND INCREASE IN SUNSHINE AND AFTERNOON TEMPERATURES THURSDAY THROUGH
NEXT SATURDAY. TJ

.AVIATION...GENERALLY VFR CONDITIONS INLAND TODAY...WITH PERIODS
OF IFR AND MVFR CONDITIONS ALONG THE COAST. THE EXCEPTION INLAND
IS SOME IFR AND MVFR CIGS IN THE SOUTHERN AND CENTRAL WILLAMETTE
VALLEY THROUGH 16Z-17Z. THERE WILL ALSO BE A PERIOD OF VFR
CONDITIONS ALONG THE COAST TODAY...BUT TIMING AND DURATION
REMAINS UNCERTAIN. IFR CONDITIONS WILL LIKELY REDEVELOP ALONG THE
COAST TONIGHT...BUT INLAND PENETRATION SHOULD BE LIMITED.

KPDX AND APPROACHES...VFR CONDITIONS TODAY AND TONIGHT.

.MARINE...HIGH PRESSURE TODAY WILL GIVE WAY TO A WEAKENING FRONT
ON MONDAY. HIGH PRESSURE WILL THEN RETURN TO THE NORTHEAST
PACIFIC TUESDAY WITH THERMAL LOW PRESSURE STRENGTHENING OVER
INTERIOR NORTHERN CALIFORNIA. THIS WILL PLACE THE WATERS IN A
FAMILIAR THIS SUMMER WITH PERIODS OF GUSTY NORTHERLY WINDS. EXPECT
SEAS TO FLUCTUATE GENERALLY BETWEEN 4 AND 7 FT WITH THE

829 AM PDT SUN AUG 31 2014

.UPDATE...ENOUGH MOISTURE WAS PROVIDED BY THE ONSHORE FLOW
OVERNIGHT TO PUSH CLOUDS ALONG THE COAST NORTH OF CAPE BLANCO AND INTO
THE UMPQUA BASIN. CLOUDS HAVE ALSO DEVELOPED UP AGAINST THE
RIDGELINES OF THE CASCADES AND THE SISKIYOUS ALONG THE ROGUE
VALLEY. THESE CLOUDS WILL BE QUICK TO BURN OFF AS THE MORNING
PROGRESSES, AND MOSTLY CLEAR SKIES SHOULD THEN CONTINUE FOR THE
REST OF THE DAY. THE EXCEPTION TO THIS RULE WILL BE SISKIYOU
COUNTY AND PORTIONS OF MODOC AND SOUTHERN LAKE AND KLAMATH
COUNTIES, WHERE SMOKE FROM WILDFIRES WILL CONTINUE TO PRODUCE
HAZY, IF NOT DOWN RIGHT SMOKEY, SKIES THROUGH THE DAY. HAVE
UPDATED THE FORECAST THIS MORNING TO ACCOUNT FOR BOTH OF THESE
FEATURES, BUT THE REMAINDER OF THE FORECAST LOOKS TO BE ON TRACK,
SO HAVE MADE NO OTHER CHANGES. FOR MORE INFORMATION, SEE THE
PREVIOUS DISCUSSION BELOW. -BPN

.AVIATION...BASED ON THE 31/12Z TAF CYCLE...
A MOIST ONSHORE FLOW WILL CONTINUE TODAY WITH IFR CIGS AND MVFR VIS
AT THE COAST...MAINLY NORTH OF CAPE BLANCO. THIS STRATUS WILL ALSO
SPREAD INTO THE COQUILLE AND UMPQUA VALLEYS WITH THE MARINE LAYER
EXPECTED TO BE AROUND 4000 FT DEEP. CONDITIONS WILL BEGIN TO IMPROVE
TO VFR AFTER 18Z. IFR CIGS RETURN TONIGHT AT KOTH.

WITH THE STEERING WINDS TURNING TO NORTHWEST, EXPECT SOME
IMPROVEMENT OF VISIBILITY IN FAR EASTERN SISKIYOU AND MODOC COUNTIES
AND CONTINUED POOR TO MODERATE VISIBILITY IN WESTERN AND CENTRAL
SISKIYOU COUNTY. HOWEVER SMOKE COULD DRIFT TO SOUTHERN SHASTA COUNTY
AND TOWARD MOUNT SHASTA THIS AFTERNOON FROM A MORE NORTHWEST
STEERING WIND. /FB


&&

.MARINE...UPDATED 800 AM PDT SUN 31 AUG 2014...WINDS WILL BEGIN TO
INCREASE THIS AFTERNOON WITH MOST OF THE INCREASE OCCURRING SOUTH OF
CAPE BLANCO. A THERMAL TROUGH WILL STRENGTHEN ON MONDAY AFTERNOON
AND LIKELY PERSIST AT LEAST THROUGH THURSDAY WITH MODERATE TO STRONG
NORTHERLY WINDS AND STEEP TO VERY STEEP WIND WAVE DOMINATED SEAS.
WINDS THROUGH THE WEEK ARE EXPECTED TO BE STRONGEST SOUTH OF GOLD
BEACH WITH WEDNESDAY AS THE WINDIEST DAY OF THE WEEK. /FB

UMPQUA VALLEY...THE ILLINOIS VALLEY...AND THE SOUTHERN AND
EASTERN RIMS OF THE ROGUE VALLEY. IT IS ALSO NOW FORMING ALONG THE
NORTH COAST AND IN THE COQUILLE VALLEY. OTHER THAN THAT...IT IS
MOSTLY CLEAR OVER THE AREA.  STILL PLENTY OF SMOKE OVER NORTHERN
CALIFORNIA FROM WILDFIRES IN WESTERN SISKIYOU COUNTY.

THE LAST OF THE SIGNIFICANT SHORT WAVES HAS MOVED OFF TO THE

WITH DRY NORTHWESTERLY FLOW ALOFT. HEIGHTS WILL RISE OVER THE
MEDFORD CWA THROUGH MONDAY...THEN LOWER A BIT TUESDAY AS SHORT
WAVES MOVING OVER THE RIDGE FLATTEN IT A BIT. FLOW ALOFT WILL
BECOME ZONAL TUESDAY.

OFFSHORE LOW LEVEL FLOW WILL DEVELOP SUNDAY NIGHT AND PERSIST INTO
TUESDAY. EXPECT MOST AREAS TO CLEAR OUT...EXCEPT POSSIBLY THE
NORTH COAST. SUNDAY HIGHS INLAND WILL BE AROUND THE SAME AS THE
SATURDAY HIGHS. EXPECT TEMPERATURES TO WARM MONDAY THROUGH TUESDAY
EVERYWHERE BUT THE UMPQUA BASIN...WHERE MONDAY WILL BE THE WARMEST
DAY. AN ONSHORE MARINE PUSH WILL BRING COOLER TEMPERATURES TO THE
UMPQUA BASIN TUESDAY.

AN UPPER TROUGH WILL DIG INTO THE PACIFIC NORTHWEST WEDNESDAY.
THIS WILL BRING COOLER TEMPERATURES TO THE AREA...WITH SLIGHTLY
BELOW NORMAL HIGH TEMPERATURES INLAND. IT WILL REMAIN DRY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
829 AM PDT SUN AUG 31 2014

.UPDATE...ENOUGH MOISTURE WAS PROVIDED BY THE ONSHORE FLOW
OVERNIGHT TO PUSH CLOUDS ALONG THE COAST NORTH OF CAPE BLANCO AND INTO
THE UMPQUA BASIN. CLOUDS HAVE ALSO DEVELOPED UP AGAINST THE
RIDGELINES OF THE CASCADES AND THE SISKIYOUS ALONG THE ROGUE
VALLEY. THESE CLOUDS WILL BE QUICK TO BURN OFF AS THE MORNING
PROGRESSES, AND MOSTLY CLEAR SKIES SHOULD THEN CONTINUE FOR THE
REST OF THE DAY. THE EXCEPTION TO THIS RULE WILL BE SISKIYOU
COUNTY AND PORTIONS OF MODOC AND SOUTHERN LAKE AND KLAMATH
COUNTIES, WHERE SMOKE FROM WILDFIRES WILL CONTINUE TO PRODUCE
HAZY, IF NOT DOWN RIGHT SMOKEY, SKIES THROUGH THE DAY. HAVE
UPDATED THE FORECAST THIS MORNING TO ACCOUNT FOR BOTH OF THESE
FEATURES, BUT THE REMAINDER OF THE FORECAST LOOKS TO BE ON TRACK,
SO HAVE MADE NO OTHER CHANGES. FOR MORE INFORMATION, SEE THE
PREVIOUS DISCUSSION BELOW. -BPN

.AVIATION...BASED ON THE 31/12Z TAF CYCLE...
A MOIST ONSHORE FLOW WILL CONTINUE TODAY WITH IFR CIGS AND MVFR VIS
AT THE COAST...MAINLY NORTH OF CAPE BLANCO. THIS STRATUS WILL ALSO
SPREAD INTO THE COQUILLE AND UMPQUA VALLEYS WITH THE MARINE LAYER
EXPECTED TO BE AROUND 4000 FT DEEP. CONDITIONS WILL BEGIN TO IMPROVE
TO VFR AFTER 18Z. IFR CIGS RETURN TONIGHT AT KOTH.

WITH THE STEERING WINDS TURNING TO NORTHWEST, EXPECT SOME
IMPROVEMENT OF VISIBILITY IN FAR EASTERN SISKIYOU AND MODOC COUNTIES
AND CONTINUED POOR TO MODERATE VISIBILITY IN WESTERN AND CENTRAL
SISKIYOU COUNTY. HOWEVER SMOKE COULD DRIFT TO SOUTHERN SHASTA COUNTY
AND TOWARD MOUNT SHASTA THIS AFTERNOON FROM A MORE NORTHWEST
STEERING WIND. /FB


&&

.MARINE...UPDATED 800 AM PDT SUN 31 AUG 2014...WINDS WILL BEGIN TO
INCREASE THIS AFTERNOON WITH MOST OF THE INCREASE OCCURRING SOUTH OF
CAPE BLANCO. A THERMAL TROUGH WILL STRENGTHEN ON MONDAY AFTERNOON
AND LIKELY PERSIST AT LEAST THROUGH THURSDAY WITH MODERATE TO STRONG
NORTHERLY WINDS AND STEEP TO VERY STEEP WIND WAVE DOMINATED SEAS.
WINDS THROUGH THE WEEK ARE EXPECTED TO BE STRONGEST SOUTH OF GOLD
BEACH WITH WEDNESDAY AS THE WINDIEST DAY OF THE WEEK. /FB

DISCUSSION...31/00Z NAM/GFS IN.

THE MARINE LAYER DEPTH CRANKED UP QUITE A BIT IN RESPONSE TO THE
TRANSITORY SHORT WAVES ALOFT. STRATUS IS COVERING THE SOUTHERN
UMPQUA VALLEY...THE ILLINOIS VALLEY...AND THE SOUTHERN AND
EASTERN RIMS OF THE ROGUE VALLEY. IT IS ALSO NOW FORMING ALONG THE
NORTH COAST AND IN THE COQUILLE VALLEY. OTHER THAN THAT...IT IS
MOSTLY CLEAR OVER THE AREA.  STILL PLENTY OF SMOKE OVER NORTHERN
CALIFORNIA FROM WILDFIRES IN WESTERN SISKIYOU COUNTY.

THE LAST OF THE SIGNIFICANT SHORT WAVES HAS MOVED OFF TO THE
EAST...AND A BROAD LONG WAVE RIDGE IS NOW BUILDING INTO THE AREA
WITH DRY NORTHWESTERLY FLOW ALOFT. HEIGHTS WILL RISE OVER THE
MEDFORD CWA THROUGH MONDAY...THEN LOWER A BIT TUESDAY AS SHORT
WAVES MOVING OVER THE RIDGE FLATTEN IT A BIT. FLOW ALOFT WILL
BECOME ZONAL TUESDAY.

OFFSHORE LOW LEVEL FLOW WILL DEVELOP SUNDAY NIGHT AND PERSIST INTO
TUESDAY. EXPECT MOST AREAS TO CLEAR OUT...EXCEPT POSSIBLY THE
NORTH COAST. SUNDAY HIGHS INLAND WILL BE AROUND THE SAME AS THE
SATURDAY HIGHS. EXPECT TEMPERATURES TO WARM MONDAY THROUGH TUESDAY
EVERYWHERE BUT THE UMPQUA BASIN...WHERE MONDAY WILL BE THE WARMEST
DAY. AN ONSHORE MARINE PUSH WILL BRING COOLER TEMPERATURES TO THE
UMPQUA BASIN TUESDAY.

AN UPPER TROUGH WILL DIG INTO THE PACIFIC NORTHWEST WEDNESDAY.
THIS WILL BRING COOLER TEMPERATURES TO THE AREA...WITH SLIGHTLY
BELOW NORMAL HIGH TEMPERATURES INLAND. IT WILL REMAIN DRY.
OFFSHORE FLOW WILL REDEVELOP TUESDAY NIGHT AND PERSIST THROUGH
WEDNESDAY NIGHT.

THE TROUGH WILL DEPART THURSDAY...BUT IT WILL LEAVE A WEAK
RESIDUAL TROUGH THAT WILL PERSIST INTO THE WEEKEND. EXPECT
CONTINUED DRY WEATHER. INLAND TEMPERATURES WILL WARM TO NEAR TO
JUST ABOVE NORMAL VALUES THURSDAY...THEN NOT CHANGE MUCH INTO THE
WEEKEND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
314 AM PDT SUN AUG 31 2014

.SYNOPSIS...CLOUDS...COOLER TEMPERATURES...AND A FEW LINGERING
SHOWERS TODAY ON THE BACKSIDE OF A DEPARTING TROUGH. THERE WILL BE
SLIGHT WARMING MONDAY WITH DRY WEATHER AS A WEAK UPPER RIDGE MOVES
OVER THE REGION. ANOTHER UPPER LEVEL TROUGH WILL BRING A RETURN OF
CLOUDY AND COOL WEATHER TUESDAY AND WEDNESDAY. OFFSHORE WINDS AND
WARMER TEMPERATURES EXPECTED LATE IN THE WEEK.

&&

.SHORT TERM...TODAY THROUGH WEDNESDAY...WATER VAPOR IMAGERY SHOWS THE
PACIFIC NW SANDWICHED BETWEEN AN UPPER RIDGE OVER THE EAST PACIFIC
AND AN UPPER TROUGH OVER THE INTER-MOUNTAIN WEST. RADAR IMAGERY SHOWS
WEAK ECHOS OFF SHORE AND ISOLATED SHOWERS ARE POSSIBLE FOR THE
COAST...COAST RANGE AND CASCADES EARLY THIS MORNING. INFRARED IMAGERY
SHOWS AREAS OF MID-LEVEL CLOUDS OFFSHORE THAT WILL MOVE OVER NW
OREGON THROUGHOUT THE DAY...AND HELP MAINTAIN SEASONABLY COOL WEATHER
TODAY.

 THE UPPER JET THAT HELPED PRODUCE LIFT OVER NW OREGON ON SATURDAY
HAS SHIFTED TO THE NORTH...RESULTING IN A DRIER NORTHWESTERLY FLOW
FOR THE REGION. THE STORM TRACK IS ALSO FURTHER NORTH...SUCH THAT THE
APPROACHING SHORTWAVE TROUGHS EMBEDDED WITHIN THE NW FLOW...WILL
REMAIN NORTH OF THE PORTLAND FORECAST AREA THE NEXT COUPLE OF DAYS.
THEREFORE THE SHORTWAVE THAT WAS EXPECTED TO BRING RAIN TONIGHT AND
MONDAY TO THE PORTLAND FORECAST AREA WILL MOST LIKELY NOT PRODUCE ANY
RAIN OVER NW OREGON. HAVE THEREFORE REDUCED POPS FOR TONIGHT AND
MONDAY ACROSS THE REGION.

WEAK UPPER LEVEL RIDGING WILL ATTEMPT TO BUILD IN MONDAY...AND THE
DAYTIME TEMPERATURES WILL WARM CLOSER TO THE SEASONAL NORMALS. THIS
WARMING WILL BE SHORT-LIVED AS ANOTHER UPPER TROUGH DROPPING SOUTH
FROM THE GULF OF ALASKA WILL BRING ADDITIONAL CLOUDY AND SEASONABLY
COOL WEATHER FOR TUESDAY. MOST OF THE SHOWERS WITH THIS TROUGH WILL
REMAIN IN CENTRAL AND NORTHERN WASHINGTON...BUT THERE MAY BE A FEW
LIGHT SHOWERS ACROSS SW WASHINGTON TUESDAY EVENING. OTHERWISE...A
DEEP MARINE LAYER WILL LIKELY RESULT IN MARINE CLOUDS PUSHING FAR
INLAND WEDNESDAY MORNING.TJ

.LONG TERM...WEDNESDAY NIGHT THROUGH SATURDAY...THE UPPER TROUGH
MOVES INLAND WEDNESDAY NIGHT. AN UPPER LEVEL RIDGE NOSES INTO WESTERN
CANADA AND NORTHERN WASHINGTON THURSDAY...BUT A LOW OFF OF CALIFORNIA
WILL MAINTAIN LOWER PRESSURE OVER NW OREGON. HIGH PRESSURE TO THE
NORTH AND EAST...WITH LOW PRESSURE TO THE SOUTH AND SOUTHEAST WILL
RESULT IN OFFSHORE WINDS ACROSS THE PORTLAND FORECAST AREA. EXPECT
AND INCREASE IN SUNSHINE AND AFTERNOON TEMPERATURES THURSDAY THROUGH
NEXT SATURDAY. TJ

&&

.AVIATION...WEAK PRESSURE GRADIENTS ACROSS WESTERN OREGON AND A
MOIST...BUT RELATIVELY UNSTABLE LOWER ATMOSPHERE SHOULD GENERALLY
KEEP CONDITIONS VFR INLAND...WITH PERIODS OF IFR AND MVFR CONDITIONS
ALONG THE COAST. HOWEVER...THERE SHOULD BE A PERIOD OF VFR CONDITIONS
ALONG THE COAST THIS AFTERNOON...BUT TIMING AND DURATION REMAINS
UNCERTAIN. THERE IS ALSO A CHANCE MVFR CONDITIONS WILL DEVELOP FOR
A FEW HOURS CENTERED AROUND 15Z THIS MORNING...BUT CONFIDENCE IS LOW
AT THIS POINT. OTHERWISE...ADDITIONAL IFR CONDITIONS WILL LIKELY
REDEVELOP ALONG THE COAST SUNDAY NIGHT...BUT INLAND PENETRATION
SHOULD BE LIMITED.

KPDX AND APPROACHES...THERE IS A CHANCE MVFR CONDITIONS WILL DEVELOP
FOR A COUPLE HOURS AROUND 15Z MONDAY...BUT OTHERWISE...EXPECT VFR
CONDITIONS THROUGH 12Z MONDAY. /NEUMAN

&&

.MARINE...HIGH PRESSURE TODAY WILL GIVE WAY TO A WEAKENING FRONT
ON MONDAY. FEW MARINE IMPACTS ARE EXPECTED. HIGH PRESSURE WILL
THEN RETURN TO THE NORTHEAST PACIFIC WITH THERMAL LOW PRESSURE
STRENGTHENING OVER INTERIOR NORTHERN CALIFORNIA. THIS WILL PLACE
THE WATERS IN A FAMILIAR THIS SUMMER WITH PERIODS OF GUSTY NORTHERLY
WINDS. EXPECT SEAS TO FLUCTUATE GENERALLY BETWEEN 4 AND 7 FT WITH
THE PREDOMINANT SWELL REMAINING AROUND 9 TO 10 SECONDS OUT OF THE
NORTHWEST THIS WEEK. /NEUMAN

324 AM MDT SUN AUG 31 2014

.SHORT TERM...STRONG SHORT WAVE TROUGH AND ASSOCIATED SURFACE COLD
FRONT MOVED THROUGH IDAHO ZONES SATURDAY EVENING WITH SHOWERS
THUNDERSTORMS AND GUSTY WINDS.  MAIN UPPER TROUGH MOVING RAPIDLY
EAST INTO THE PLAINS STATES TODAY WITH DRIER AND COOLER NWLY FLOW
ALOFT INTO OUR CWA.  ERN VALLEY COUNTY/ID STILL HAS A CHANCE OF
LIGHT RAIN SHOWERS TODAY BUT THE REST OF OUR CWA WILL BE DRY.
BREEZY POST-FRONTAL WESTERLY WINDS IN THE MAGIC VALLEY AND NEARBY
ZONES TODAY.  MOSTLY CLEAR AND COOLER TONIGHT WITH DIMINISHING
WINDS.  AIR MASS WILL NOT BE DRY ENOUGH FOR MAXIMUM RADIATIONAL
COOLING BUT IT WILL DEFINITELY BE COOLER THAN THIS MORNING WITH MIN
TEMPS IN THE 30S AT MOUNTAINS STATIONS AND 40S TO LOWER 50S IN THE
VALLEYS.  HIGHS MONDAY WILL BE ABOUT 2 DEGS WARMER THAN TODAY ALONG
WITH LESS WIND.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...WESTERLY FLOW WILL
DEVELOP OVER THE REGION ON TUESDAY AS THE NEXT UPPER LEVEL TROUGH
CONTINUES TO DIG SOUTH ALONG THE CANADIAN WEST COAST.  VERY LITTLE
MOISTURE WITH THIS SYSTEM SO EXPECT DRY CONDITIONS TO CONTINUE
OVER THE FORECAST AREA TUESDAY ALONG WITH TEMPERATURES WARMING BACK
TO NEAR NORMAL.  LATEST MODEL RUNS CONTINUE TO SPLIT THIS SYSTEM AS
IT MOVES TO THE EAST...WITH THE ECMWF THE FASTEST IN MOVING THE
NORTHERN SECTION EAST ALONG THE CANADIAN BORDER.  00Z RUN OF THE GFS
MORE IN LINE WITH THE PREVIOUS ECMWF...BUT WILL CONTINUE TO TREND
TOWARD THE STRONGER AND FASTER ECMWF DUE TO BETTER RUN TO RUN
CONSISTENCY COMPARED TO THE GFS.  GOING WITH THE TIMING OF THE
ECMWF...WILL SEE A DRY COLD FRONT MOVE OVER THE FORECAST AREA
TUESDAY NIGHT INTO WEDNESDAY WITH TEMPERATURES COOLING TO A FEW
DEGREES BELOW NORMAL.  AS THE NORTHERN SECTION OF THE TROUGH MOVES
TO THE EAST THE SOUTHERN SECTION WILL KEEP A TROUGH OVER THE REGION
THROUGH THE END OF THE WEEK FOR COOLER THAN NORMAL TEMPERATURES AND
SLIGHT CHANCE OF PRECIPITATION OVER THE WEST CENTRAL AND BOISE
MOUNTAINS.  BY THE WEEKEND ECMWF FINALLY MOVES THE UPPER LEVEL
TROUGH TO THE EAST WITH TEMPERATURES WARMING BACK TO NEAR NORMAL
WITH SLIGHT CHANCE POPS REMAINING OVER THE WEST CENTRAL AND BOISE
MOUNTAINS.
