NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
831 PM PDT MON SEP 15 2014

.SYNOPSIS...SMOKE FROM THE 36 PIT WILDFIRE WILL IMPACT MOST OF NW 
OREGON AND SW WASHINGTON THROUGH TONIGHT. AN UPPER LEVEL TROUGH WILL 
BRUSH THE REGION TONIGHT...POSSIBLY TRIGGERING SOME DRY 
THUNDERSTORMS OVER THE AREA...BUT CONFIDENCE IS LOW. THIS TROUGH 
WILL ALSO BRING A RETURN OF LOW MARINE CLOUDS TO THE AREA...AND HELP 
COOL TEMPERATURES FOR TUESDAY. A WEAKENING STORM SYSTEM WILL BRING A 
CHANCE FOR RAIN SHOWERS LATE WEDNESDAY INTO EARLY THURSDAY. HIGH 
PRESSURE WILL LIKELY REBUILD FRIDAY WITH DRY AND WARMER CONDITIONS 
RETURNING NEXT WEEKEND. 

&&

.SHORT TERM...EVENING UPDATE...INCREASING SW FLOW IS IMPACTING THE
SOUTH WILLAMETTE VALLEY THIS EVENING AS THE NEGATIVELY TILTED
SHORTWAVE CONTINUES LIFTING NORTH TOWARDS THE FORECAST AREA. MID TO
HIGH CLOUDS HAVE SPREAD ACROSS MUCH OF THE REGION. GUSTY SW WINDS ARE
CURRENTLY IMPACTING THE SOUTH WILLAMETTE VALLEY...AS TEMPERATURES
CONTINUE TO DROP THIS EVENING. HAVE BEEN WATCHING FOR HOW DENSE THE
MARINE STRATUS WOULD BE GETTING AT NEWPORT THIS EVENING...WHICH WILL
BE A GOOD INDICATION FOR HOW MUCH WILL SPILL INTO THE WILLAMETTE
VALLEY OVERNIGHT. STILL EXPECTING THE SOUTH WILLAMETTE VALLEY SEEING
SOME SCATTERED LOW CLOUDS LATER TONIGHT AS SW FLOW PERSISTS...BUT RAW
MODEL AND MOS GUIDANCE IS STILL NOT JUMPING ON A STRONG MARINE PUSH
ELSEWHERE ACROSS THE VALLEY TONIGHT. 

WILL ALSO MAINTAIN THE CURRENT THREAT FOR DRY THUNDERSTORMS
TONIGHT... ESPECIALLY SINCE THERE IS STILL SOME DIFFLUENT FLOW ALOFT
ASSOCIATED WITH THE APPROACHING SHORTWAVE. HAVE NOT SEEN MUCH IN THE
WAY OF LIGHTNING...BUT STILL CANNOT RULE OUT A STRIKE OR TWO AS THE
SHORTWAVE PROGRESSES FURTHER NORTH. /27

SOUTHWEST WINDS SPILLING THROUGH THE COAST RANGE GAPS ACROSS THE
SOUTHERN AND CENTRAL WILLAMETTE VALLEY SHOULD HELP TO CLEAR OUT SOME
OF THE SMOKE ASSOCIATED WITH THE 36 PIT FIRE BURNING SE OF ESTACADA
OREGON TONIGHT. STRONGER WESTERLY FLOW TUESDAY SHOULD ALSO ASSIST IN
MOST SMOKE SPREADING EASTWARD AWAY FROM THE WILLAMETTE VALLEY.
NONETHELESS...LIGHT DOWN VALLEY WINDS WILL LIKELY ALLOW THICK SMOKE
AND AIR QUALITY ISSUES TO PERSIST IN NEARBY TOWNS LIKE ESTACADA. 

A SHORTWAVE TROUGH CURRENTLY NEAR 140W AND 35N WILL APPROACH THE WEST
COAST WEDNESDAY INTO THURSDAY. MODELS CONTINUE TO WAVER ON THE
DETAILS WITH THIS SYSTEM AS THE UPPER LEVEL LOW PRESSURE TRIES TO
SPLIT FROM THE MEAN FLOW AND DIVE INTO THE DESERT SOUTHWEST. AS OF 
NOW...THE MAIN GLOBAL MODELS...THE GFS AND EC...SUGGEST AT LEAST 
SOME LIGHT RAIN SHOWERS ARE LIKELY ACROSS THE AREA LATE WEDNESDAY 
INTO EARLY THURSDAY. HOWEVER...GIVEN THE SPLITTY NATURE OF THE 
SYSTEM...AND THIS WILL BE THE FIRST SYSTEM TO MOVE INTO THE HIGH 
PRESSURE IN QUITE SOME TIME...MODELS ARE LIKELY TOO AGGRESSIVE WITH 
RAIN CHANCES FOR THE REGION. AS A RESULT...POPS WERE GENERALLY KEPT 
IN THE 2O TO 50 PERCENT RANGE. WITH THAT SAID...THERE IS A BIT OF 
ELEVATED INSTABILITY WEDNESDAY AFTERNOON AND EVENING ACROSS THE AREA 
SO THERE IS A SLIGHT CHANCE FOR ELEVATED THUNDERSTORMS TO DEVELOP. 
AT THIS POINT...THUNDER WORDING WAS PRIMARILY LIMITED TO THE CENTRAL 
OREGON CASCADE FOOTHILLS AND MOUNTAINS. 

ALL IN ALL...TEMPERATURES WILL REMAIN MUCH CLOSER TO NORMAL THIS WEEK
THAN IN RECENT DAYS. /NEUMAN

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...FRIDAY THROUGH
MONDAY...GFS...DGEX...AND ECMWF ALL SHOW A UPPER-LEVEL TROUGH OVER
THE WEST COAST ON FRIDAY. THE SURFACE LOW ASSOCIATED WITH THIS SYSTEM
WILL MOVE ON-SHORE ON FRIDAY... TRANSITIONING OUR AREA TO
NORTHWESTERLY FLOW AT LOWER LEVELS. THE COLD FRONT WILL THEN PROGRESS
OFF TO THE NORTHEAST EARLY SATURDAY ENDING CHANCES FOR RAINFALL LATE
FRIDAY NIGHT. HIGH PRESSURE LOOKS TO MOVE ONSHORE TO OUR NORTH ON
SATURDAY BEHIND THE FRONT...BRIEFLY BRINGING BACK EASTERLY WINDS
WHICH WILL WARM TEMPERATURES ON SATURDAY. THE MODELS ARE IN AGREEMENT
THOUGH THAT A WEAK...DRY FRONTAL BOUNDARY WILL MOVE THROUGH SUNDAY
WHICH WILL SERVE TO SHIFT WINDS BACK TO THE WEST OR SOUTHWEST. THE
WESTERLY COMPONENT WILL BRING IN MARINE AIR WHICH WILL SLIGHTLY COOL
TEMPERATURES SUNDAY AND MONDAY. -MCCOY

&&

.AVIATION...ONSHORE FLOW NOW INCREASING ACROSS REGION...MAINLY IN
FAR SOUTH INTERIOR WHERE GUSTY W TO SW WINDS ARE BLOWING AT
CORVALLIS AND EUGENE. COASTAL AREAS HAVE WIDESPREAD LOW MVFR CIGS
WITH POCKETS OF IFR CIGS. WITH UPPER LOW OFF S OREGON COAST...
THE DECK ALONG THE COAST WILL REMAIN BROKEN...BUT SHOULD SOLIDIFY
LATER TONIGHT AND REMAIN THROUGH GOOD PART OF TUE. FURTHER
INLAND... CONDITIONS REMAIN VFR TONIGHT...THOUGH WILL HAVE
SCATTERED TO BROKEN LOW MVFR TO S OF KSLE FROM 12Z TO 18Z TUE. 
WILL HAVE TO WAIT FOR TUE NIGHT FOR WIDESPREAD CIGS INLAND. 

KPDX AND APPROACHES...VFR TONIGHT AND TUE AS VARIABLE HIGH CLOUDS
DRIFT OVERHEAD IN THE S TO SW FLOW ALOFT.    ROCKEY.
&&

.MARINE...NOT MUCH CHANGE. WEAK LOW PRES OVER THE NE PAC WILL
MAINTAIN A S TO SW WIND FOR NEXT SEVERAL DAYS...BUT GENERALLY 15
KT OR LESS. MIX OF WAVE TRAINS WITH VARYING PERIODS...BUT MAJORITY
ARE FROM THE W TO NW AND RUNNING AT 4 TO 6 FT. 

HIGH PRES WILL REBUILD OVER THE WATERS FRI AND SAT...WITH ANOTHER
THERMAL LOW PRES OVER NW CALIF. THIS WILL BRING ANOTHER ROUND OF
N WINDS TO THE WATERS...WITH SEAS 5 TO 7 FT. 
&&

.PQR WATCHES/WARNINGS/ADVISORIES...
OR...RED FLAG WARNING UNTIL MIDNIGHT PDT TONIGHT FOR ZONE 602-ZONE 
     603-ZONE 604-ZONE 605-ZONE 606-ZONE 607-ZONE 608.
