NWS Forecaster Discussion



AREA FORECAST DISCUSSION 
NATIONAL WEATHER SERVICE PORTLAND OR 
823 PM PST TUE JAN 27 2015

.SYNOPSIS...A WEAK FRONTAL SYSTEM ALONG THE COAST WILL SLOWLY MOVE
INLAND OVER THE NORTH PART OF THE FORECAST AREA TONIGHT AND
WEDNESDAY...LINGER INTO WEDNESDAY NIGHT...THEN MOSTLY DISSIPATE AND
MOVE OUT OF THE AREA THURSDAY. ANOTHER UPPER RIDGE IS EXPECTED TO
DEVELOP OVER THE PACIFIC NORTHWEST LATER IN THE WEEK AND CONTINUE
INTO THE WEEKEND FOR MORE DRY WEATHER. THE NEXT CHANCE FOR RAIN IS
PROBABLY NOT UNTIL LATER SUNDAY AND MONDAY.

&&

.SHORT TERM...TONIGHT THROUGH FRIDAY...LIGHT RAIN CONTINUES OVER MUCH
OF THE FORECAST AREA BUT IS FAIRLY SPOTTY OVER THE INTERIOR LOWLANDS.
THIS WEAK FRONTAL SYSTEM WILL CONTINUE TO BRING PERIODS OF LIGHT 
RAIN TONIGHT.  THE FRONTAL BOUNDARY APPEARS TO LAY ALONG THE NORTH 
COAST INTO SW WASHINGTON.  MODELS CONTINUE TO SHOW SOME LIGHT 
PRECIPITATION FOCUSED ALONG THIS FRONTAL BAND INTO WEDNESDAY NIGHT 
BEFORE DRYING OUT AND LIFTING NORTH THURSDAY. THE WEAK ASSOCIATED 
UPPER TROUGH TAKES UNTIL THURSDAY AND THURSDAY NIGHT BEFORE IT MOVES 
OUT OF THE AREA...SO THIS SEEMS REASONABLE. SO OVERALL WE SHOULD SEE 
PLENTY OF CLOUDS THE NEXT COUPLE OF DAYS WITH LESS FOG 
COVERAGE...EXCEPT PERHAPS IN THE SOUTH WILLAMETTE VALLEY.

THE GRADIENTS ARE PRETTY WEAK FROM THE NORTH THURSDAY...SO THEY MAY
NOT BE ENOUGH TO BREAK UP THE LOW CLOUDS MUCH THURSDAY AFTERNOON. THE
ONE EXCEPTION MIGHT BE NEAR TROUTDALE...AS WE START TO GET ABOUT A 4
MB EASTERLY GRADIENT THROUGH THE GORGE BY THURSDAY AFTERNOON.

AN UPPER RIDGE BUILDS IN THURSDAY NIGHT AND FRIDAY...BUT THE MAIN
IMPACT WILL BE TO MAINTAIN OR SLIGHTLY STRENGTHEN OUR TEMPERATURE
INVERSION SOME...THOUGH NOT NEARLY AS STRONG WHAT WE SAW LAST
WEEKEND. SHOULD SEE MORE FOG COVERAGE FRIDAY MORNING. THE LIGHT
EASTERLY GRADIENT THROUGH THE GORGE CONTINUES...AND WE DO GET A LIGHT
NORTHERLY GRADIENT SOUTHWARD ALONG THE WILLAMETTE VALLEY...SO WE WILL
HAVE TO SEE IF THIS IS ENOUGH TO BREAK UP THE LOW CLOUDS AND FOG SOME
FRIDAY AFTERNOON. TOLLESON

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...THE UPPER RIDGE CONTINUES
THROUGH SATURDAY OFF THE PACNW COAST AS A HIGH AMPLITUDE PATTERN IN
THE NORTH PACIFIC CONTINUES. THIS WILL MEAN DRY WEATHER WITH FOG IN
THE INTERIOR VALLEYS WHILE THE MOUNTAINS WILL BE MILD NEARLY CLOUD
FREE.  MODELS ARE CONTINUE TO SHOW THE RIDGE SHIFTING INLAND AS A
MORE CONSOLIDATED JETSTREAM APPROACHES THE WEST COAST. ECMWF...GFS
AND GFS ENSEMBLE MEAN ARE IN GOOD AGREEMENT IN BRINGING A WARM FRONT
THROUGH THE AREA LATE SUNDAY INTO MONDAY. THE ECMWF FLATTENS THE
RIDGE MORE SO SNOW LEVELS WILL BE LOWER BUT STILL ABOVE MOST CASCADE
PASSES. WITH THE WEAKER RIDGE AND STRONGER JET STREAM POINTED INTO
THE REGION WE CAN EXPECT MORE CLOUDS AND HIGHER CHANCES FOR RAIN FOR
THE REMAINDER OF THE LONG TERM.  OVERALL HAVE INCREASED POPS SUN
NIGHT THROUGH TUE WITH EMPHASIS ON SUN NIGHT AND MONDAY.  THERE MAY
BE ANOTHER FRONT TUE BUT MODEL SOLUTIONS DIVERGE REGARDING THIS
FEATURE. /26
&&

.AVIATION...STALLED WEAK FRONTAL BOUNDARY WILL MAINTAIN A VARIETY
OF FLIGHT CONDITIONS TONIGHT. MOSTLY MVFR AND IFR CONDITIONS WILL
PERSIST ALONG THE COAST. THE LOWER ATMOSPHERE WILL STABILIZE A
BIT TONIGHT...AND WEAK FLOW COUPLED WITH CONTINUED MOISTURE FROM
LIGHT DRIZZLE SHOULD PROVIDE FOR SOME LOWERING TO LOWER MVFR OR
IFR ACROSS THE INTERIOR. THE CENTRAL AND SOUTH VALLEY...ALONG WITH
KHIO...MAY SEE SOME LOCALIZED AREAS OF FOG FORM AGAIN...BUT EXPECT
THIS TO BE LESS PREVALENT IN THE NORTH WITH INCREASED MIXING FROM
AN UPPER LEVEL BOUNDARY. GENERAL TREND OF IMPROVING CIGS TO 3000
FT OR ABOVE EXPECTED ON WEDNESDAY FROM 20Z ONWARD.

KPDX AND APPROACHES...PREDOMINANTLY MVFR AND IFR CONDITIONS WITH
CIGS BETWEEN 1000-1500 FT WILL CONTINUE THROUGH AT LEAST 06Z WED.
WILL SEE CIGS OCCASIONALLY DROP TO 500 FT TONIGHT...ESPECIALLY
FROM 06Z-12Z WED. CONDITIONS SHOULD IMPROVE TO VFR AFTER 16Z WED
MORNING. /27

&&

.MARINE...WINDS REMAIN 15 KT OR LESS OVER THE WATERS TONIGHT. A
WEAK LOW PRES DRIFTS NORTHEAST NEAR THE OUTER WATERS ON WED AND
WILL SHIFT WINDS BUT THEY REMAIN LIGHT. THEN...HIGH PRES REBUILDS
OVER THE WATERS THU AND HOLDS THROUGH THE END OF THE WEEK. N WINDS
MAY INCREASE LATE THU AND FRI AS LOW PRES BUILDS UP THE S OREGON
COAST...WITH A CHANCE OF GUSTS APPROACHING SMALL CRAFT ADVISORY
CRITERIA OVER THE CENTRAL OREGON WATERS. OTHERWISE...N WINDS
CONTINUE OVER THE WATERS THROUGH SUNDAY WHEN WINDS TURN S AHEAD OF
A STRONGER FRONTAL SYSTEM.

SEAS REMAIN NEAR 6 FT THIS EVENING AND WILL HOLD BETWEEN 5 FT AND
7 FT THROUGH THE END OF THE WEEK. A MIX OF TWO W SWELLS...ONE
AROUND 18 SECONDS AND ANOTHER AROUND 11 SECONDS...WILL ENTER THE
WATERS WED NIGHT THROUGH THU NIGHT. OTHERWISE...NO CONCERNS ON THE
WATERS UNTIL SUN WHEN SEAS MAY BUILD TO NEAR 9 OR 10 FT WITH THE
FRONTAL SYSTEM.  CULLEN
