NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
230 PM PDT TUE SEP  2 2014

.SYNOPSIS...A PACIFIC FRONT WILL BRING INCREASING CLOUDS AND A
CHANCE FOR LIGHT RAIN SHOWERS TO MAINLY SOUTHWEST WASHINGTON AND 
EXTREME NORTHWEST OREGON LATE THIS AFTERNOON AND TONIGHT. CLOUDY 
SKIES ON WEDNESDAY WILL KEEP TEMPERATURES NEAR TO SLIGHTLY BELOW 
NORMAL ON WEDNESDAY. STRENGTHENING OFFSHORE WINDS WILL ALLOW 
TEMPERATURES TO RISE INTO THE UPPER 80S AND LOW 90S FOR MANY INLAND 
LOCATIONS LATE IN THE WORK WEEK. THERE IS A CHANCE ANOTHER STORM 
SYSTEM COULD BRING A CHANCE FOR LIGHT RAIN SHOWERS TO THE AREA EARLY 
NEXT WEEK.  
 
&&

.SHORT TERM...TONIGHT THROUGH FRIDAY... AN UPPER LEVEL TROUGH AND
ATTENDANT PACIFIC FRONT MOVING INTO THE WA COAST THIS AFTERNOON WILL
PUSH SOUTHEASTWARD ACROSS THE NORTHERN HALF OF THE AREA THIS EVENING.
THIS WILL BRING A FEW LIGHT SHOWERS ACROSS SOUTHWEST WASHINGTON...AND
THE WEST FACING SLOPES OF THE NORTH OREGON CASCADES AND COAST RANGE.
RAINFALL WILL BE QUITE LIGHT WITH THIS SYSTEM WITH ONLY A FEW
HUNDREDTHS TO PERHAPS A COUPLE OF TENTHS OF PRECIPITATION EXPECTED. 
CLOUD COVER ASSOCIATED WITH THE UPPER LEVEL TROUGH WILL KEEP HIGH 
TEMPERATURES DOWN TO A COUPLE DEGREES BELOW NORMAL TO NEAR NORMAL 
AGAIN WEDNESDAY.

OFFSHORE FLOW WILL DEVELOP THURSDAY AS THERMAL LOW PRESSURE BUILDS 
NORTHWARD ALONG THE COAST. THIS PATTERN WILL PERSIST THROUGH 
SATURDAY AND WILL RESULT IN TEMPERATURES WARMING INTO THE MID 80S TO 
AROUND 90 IN THE WILLAMETTE VALLEY THURSDAY THROUGH SATURDAY. 
COASTAL TEMPERATURES WILL ALSO RISE INTO THE SEVENTIES DURING THIS 
PERIOD. NO RECORD TEMPERATURES ARE EXPECTED THOUGH AS RECORD TEMPS 
ARE IN THE UPPER 80S AND 90S AT THE COAST AND UPPER 90S AND EVEN LOW 
100S FOR THE VALLEY.

ON THE FIRE WEATHER FRONT...POOR NIGHT TIME RELATIVE HUMIDITY 
RECOVERIES AND MODEST EAST WINDS ACROSS THE CASCADES AND COAST RANGE 
WILL ENHANCE FIRE WX CONCERNS THE LATTER PART OF THE WEEK. TW
 
.LONG TERM...SATURDAY THROUGH TUESDAY...A REX-LIKE WEATHER PATTERN 
WITH A RIDGE POSITIONED NORTH OF A TROUGH IS FORECAST TO MOVE 
ONSHORE AS THE RIDGE BREAKS DOWN ON SATURDAY. THE LONGWAVE TROUGH 
WILL BE OUR NEXT WEATHER-MAKER WHEN THE RIDGE WEAKENS ENOUGH TO 
ALLOW THE LOW-PRESSURE SYSTEM ONSHORE...WHICH THE ECMWF...GFS...AND 
DGEX AGREE SHOULD BE SOMETIME LATE SUNDAY NIGHT OR EARLY MONDAY 
MORNING. RAINFALL WITH THIS SYSTEM WILL START AT THIS TIME...AND THE 
UNSTABLE NORTHWESTERLY FLOW PATTERN THAT SETS UP BEHIND THIS SYSTEM 
BRING CONTINUED CHANCES OF RAIN THROUGH TUESDAY WITH A LOT OF 
UNCERTAINTY ON TIMING AND LOCATION. -MCCOY

&&

.AVIATION...GENERALLY VFR ACROSS THE REGION THIS AFTERNOON WITH
SCT-BKN VFR DECK BETWEEN 3000-4000 FT....THOUGH MVFR CIGS ARE
APPROACHING THE S WASHINGTON/N OREGON COAST NEAR KAST AS A
WEAKENING COLD FRONT MOVES TOWARDS THE AREA. THE FRONT WILL PASS
THROUGH THE NORTHERN HALF OF THE FORECAST AREA WITH LOW VFR TO
MVFR CIGS ALONG THE COAST BY 00Z...AND PUSHING INTO THE INTERIOR
AROUND 03Z. CHANCE FOR SOME -RA N OF A GENERALLY KTMK-KSLE LINE.
WITH DECENT ONSHORE FLOW...EXPECT MVFR CIGS ACROSS MUCH OF THE
INTERIOR 12Z-18Z WED WITH GENERAL CLEARING THEREAFTER. LOWER MVFR
OR PERHAPS IFR POSSIBLE AT THE COAST TONIGHT THROUGH EARLY WED...BUT
EXPECT STRATUS TO PUSH LARGELY OFFSHORE AROUND 19Z OR 20Z WED. WINDS
ALONG THE OREGON COAST MAY BE GUSTY WED EVENING...PARTICULARLY
FROM KONP TO K6S2.

KPDX AND APPROACHES...VFR CONDITIONS CONTINUE THIS AFTERNOON WITH
SCATTERED LAYER AROUND 3000 FT. CIGS GRADUALLY DEVELOP AND LOWER
FROM 5000 FT INTO LOWER VFR TO MVFR THIS EVENING WITH THE
APPROACHING WEAK FRONT. SLIGHT CHANCE OF A SHOWER THIS EVENING TO
EARLY TONIGHT. CONTINUED ONSHORE FLOW WILL BRING MVFR CIGS BY 12Z
LASTING UNTIL AROUND 17Z-18Z...WITH VFR UNDER MOSTLY CLEAR SKIES
THEREAFTER. CULLEN


&&

.MARINE...A WEAKENING COLD FRONT WILL MOVE ACROSS THE WATERS THIS
EVENING. BEHIND THE FRONT TONIGHT...WINDS WILL SHIFT N-NW AND
INCREASE TO NEAR 20 KT...ESPECIALLY OVER THE NORTHERN OUTER
WATERS. CANNOT RULE OUT OCCASIONAL GUSTS TO 23-25KT OVER THIS
AREA...BUT DO NOT EXPECT THESE TO BE WIDESPREAD ENOUGH TO ISSUE A
SMALL CRAFT ADVISORY. A NW SWELL MAY BUILD SEAS IN THESE AREAS
TO NEAR 9 FT TONIGHT AS WELL.

FROM WED THROUGH THE SECOND HALF OF THE WEEK...N-NW WINDS CONTINUE
AS HIGH PRES REBUILDS IN OFFSHORE AND A THERMAL LOW PRES OVER
CALIFORNIA EXTENDS N INTO OREGON. GUSTS UP TO 20-25 KT ARE
POSSIBLE OVER THE CENTRAL OREGON WATERS WED...AND APPEAR LIKELY
OVER ALL WATERS THU AND FRI. MEANWHILE...SEAS WILL BUILD TO 7 TO
9 FT...DOMINATED BY A COMBINATION OF WIND WAVE AND FRESH SWELL.
FORECAST MODELS KEEP SEAS BELOW 10 FT...BUT WILL NEED TO MONITOR
TRENDS AS STRONGEST WINDS MAY BUILD SEAS INTO THE 9 TO 11 FT
RANGE. WINDS LOOK TO EASE BY SUN AS HIGH PRES IN NE PAC WEAKENS
AND THERMAL LOW PRES SHIFTS INLAND. CULLEN
