AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
914 PM PST TUE MAR  8 2016

.SYNOPSIS...THE NEXT STRONG LOW PRESSURE SYSTEM WILL LIFT A WARM
FRONT THROUGH SOUTHWEST OREGON EARLY WEDNESDAY MORNING...THEN NORTH
TO SOUTHWEST WASHINGTON BY LATE AFTERNOON. EXPECT VERY STRONG WIND
TO DEVELOP ALONG THE COAST AND OVER THE OREGON COAST RANGE AND
SOUTHWEST WASHINGTON WILLAPA HILLS LATE WEDNESDAY AFTERNOON AND
CONTINUE THROUGH THE NIGHT. THE COLD FRONT BECOMES MORE NORTH-TO-
SOUTH ORIENTED WEDNESDAY EVENING AND FINALLY MOVES INLAND OVERNIGHT.
HEAVY RAIN WILL ACCOMPANY THE FRONT...ESPECIALLY OVER THE COASTAL
AREAS. THERE SHOULD BE A BRIEF LULL IN THE ACTION LATE THURSDAY AND
THURSDAY NIGHT. SEVERAL MORE SYSTEMS ROTATE ACROSS THE AREA FRIDAY
THROUGH EARLY NEXT WEEK. &&

.SHORT TERM...SHOWERS ARE ON THE DECREASE THIS EVENING BUT THE BREAK
WILL NOT LAST VERY LONG AS THE ATTENTION TURNS TO A RAPIDLY
DEVELOPING SYSTEM OVER THE NE PACIFIC. WATER VAPOR LOOP SHOWS AN
IMPRESSIVE ARCHING JET FROM NORTH OF HAWAII TOWARD THE PACNW. GOES
WEST 275-225 MB LAYER WINDS MEASURED AT AROUND 170 KT WHICH IS
SOMEWHAT UNUSUAL THIS TIME OF YEAR. ALL MODELS INDICATE A RAPIDLY
DEVELOPING SURFACE LOW PRES NOW NEAR 36N 147W.	THIS LOW WILL CURVE
TO THE NE AND COME WITHIN 330 MI OFF THE OREGON COAST LATE WED
AFTERNOON WITH MINIMUM PRES BETWEEN 965 AND 973 MB. TO VARYING
DEGREES THE NAM...GFS...ECMWF ARE ALL SHOW A SECONDARY LOW
DEVELOPMENT ON THE COLD FRONT THAT SWINGS CLOSER TO THE COAST WED
NIGHT. THESE FEATURES HAVE THE POTENTIAL TO PRODUCE VERY STRONG WIND
IN MANY AREAS WED AFTERNOON THROUGH WED NIGHT. NAM CONTINUES TO SHOW
75-80 KT 925 MB SPEEDS ALONG THE COAST 00Z THU. THE GFS SHOWS 75-85
KT 850 MB WIND SPEEDS ALONG THE COAST 00Z TO 06Z THU AND 60-80 KT
OVER THE OREGON COAST RANGE AND SW WA WILLAPA HILLS. EVEN THE 4KM
WRF-GFS INDICATES 70-75 KT WIND GUSTS ALONG THE COAST WED EVENING. A
GOOD RULE OF THUMB IS THAT THE 4KM WRF 10M GUSTS ARE SIMILAR TO MAX
WIND SPEEDS IN MPH. THE 4KM NAM SOUNDING FOR KAST ALSO SHOWS 65-75
KT AT 2000 TO 3000 FT MSL 03Z THU AND CLOSE TO 90 KT AT 4000 FT.
INLAND AREAS WILL BE BREEZY WED NIGHT WITH GUSTS APPROACHING 40 MPH
IN THE WILLAMETTE VALLEY AND INTERIOR ZONES IN SW WASHINGTON AS THE
COLD FRONT MOVES THROUGH LATE IN THE EVENING.

THE WELL DEFINED WARM FRONT INTO SW WA AROUND 00Z THU...ALTHOUGH
MODELS TEND TO BE TOO FAST WITH WARM-FRONTAL TIMING. OVER-RUNNING
WARM-FRONTAL PRECIP IS EXPECTED TO ENTER THE SOUTH PART OF THE
FORECAST AREA...LANE COUNTY...AS EARLY AS 12Z WED. THE PRECIP THEN
SPREADS NORTH THROUGH THE MORNING REACHING SW WA BY 18Z OR A LITTLE
AFTER.

SNOW LEVELS IN THE SW WA AND FAR N OREGON CASCADES WED MORNING WILL
REMAIN FAIRLY LOW...AROUND 3000 TO 3500 FT AND THE INCREASING
OFFSHORE LOW-LEVEL FLOW WILL HELP TO KEEP SNOW LEVELS SUPPRESSED.
WITH THE EXPECTED QPF AMOUNTS HAVE DECIDED TO ISSUE A WINTER WEATHER
ADVISORY FOR THE N OREGON AND S WA CASCADES FOR WED.

THE OFFSHORE GRADIENT WILL STRENGTHEN LATE TONIGHT THROUGH WED
MORNING RESULTING IN INCREASING WIND THROUGH THE COLUMBIA RIVER
GORGE. NAM RUN STILL SHOWS AROUND -5 MB KTTD-KDLS GRADIENT...BUT IT
WILL LIKELY END UP CLOSER TO -6 OR -7 MB. THIS WOULD YIELD WIND GUSTS
UP TO 50 MPH IN THE WINDIEST LOCATIONS.

THE 12Z GFS INTEGRATED WATER VAPOR TRANSPORT PRODUCT VALID 12Z WED
INDICATES VALUES IN EXCESS OF 750 WITHIN THE OFFSHORE BAROCLINIC
BOUNDARY. THE 48-HR PRODUCT HAS 250-500 VALUES AIMED AT THE OREGON
AND S WA COAST...WITH EVEN HIGHER VALUES DIRECTED AT THE CENTRAL
CALIFORNIA COAST. THE GFS AND ECMWF DEPICT THE COLD FRONT SHIFTING
MORE TO A NORTH-TO-SOUTH ORIENTATION LATE WED THROUGH WED NIGHT.
INLAND AREAS...ESPECIALLY NEAR THE CASCADES...MAY NOT SEE MUCH QPF
00Z-12Z THU. MODELS ALSO SHOW THE FRONTAL BOUNDARY SPLITTING...WITH
THE MAIN PIECE CENTERED OVER NRN CAL AND SW OREGON. FORECAST QPF
06Z-18Z THU MAY BE A LITTLE HIGH...ESPECIALLY IF THE SPLIT OCCURS.
LATEST FORECAST QPF DOES NOT SHOW ANY RIVER EXCEEDING FLOOD STAGE.
HOWEVER...WILL NEED TO WATCH SW WA AS THE GFS IS SHOWING A 2 INCH
6-HR QPF BULLSEYE ALONG THE S WA COAST 00Z-06Z THU. THE ECMWF IS
ABOUT ONE-HALF OF THE GFS.

THERE LOOKS TO BE A LULL IN THE ACTIVE PATTERN THU AFTERNOON THROUGH
FRI MORNING. MODELS DEVELOP ANOTHER LOW NEAR 40N 130W 12Z FRI WITH
WRAP-AROUND MOISTURE SPREADING INTO SW OREGON. THE UPPER LOW
EVENTUALLY MAKES LANDFALL CLOSE TO KBOK 00Z SAT. WOULD NOT BE
SURPRISED IF A DEFORMATION ZONE DEVELOPED AHEAD OF THE LOW...WITH
STEADIER PRECIP SPREADING ACROSS THE FORECAST AREA FRI AFTERNOON AND
EVENING. MH/WEISHAAR

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...THE ACTIVE WEATHER
PATTERN WILL PERSIST THROUGH THE LONG TERM AS WELL. ECMWF AND GFS
SHOW ANOTHER WELL-DEFINED FRONT REACHING THE COAST NEAR 12Z SAT. THIS
ONE SHOULD BRING SEVERAL INCHES OF SNOW TO THE CASCADES...WITH
1000-500 MB THICKNESS VALUES DOWN TO THE LOWER 530S BY 00Z SUN. BEST
FORCING AND DYNAMICS APPEAR TO BE FOCUSED ON THE CENTRAL AND SOUTH
OREGON CASCADES. MODELS SHOW MORE VARIANCE BEYOND SAT. THE ECMWF
DEVELOPS ANOTHER LOW IN THE SRN JET STREAM BRANCH 18Z SUN WHILE THE
GFS CONTINUES WITH AN ELONGATED UPPER TROUGH. SHOULD THE ECMWF
VERIFY...ANOTHER COASTAL WIND EVENT WOULD BE POSSIBLE SUN AFTERNOON.
A BROAD UPPER TROUGH PERSISTS INTO EARLY NEXT WEEK...FOR ADDITIONAL
CASCADE SNOWFALL AND BELOW-NORMAL DAYTIME TEMPERATURES. WEISHAAR
&&

.AVIATION...LOW LEVEL MOISTURE AHEAD OF A WARM FRONT WILL KEEP
CEILINGS PRIMARILY IN MVFR CATEGORY OVERNIGHT...ALTHOUGH PERIODS OF
IFR OR VFR CIGS MAY AT TIMES OCCUR. A WARM FRONT WILL SPREAD
INCREASING RAIN IN FROM THE SOUTH STARTING WED MORNING. THE FRONT
WILL GRADUALLY LIFT NORTHWARD THROUGH THE FCST AREA DURING THE DAY.
EXPECT VISIBILITIES ALSO TO LOWER MVFR CATEGORY FROM SOUTH TO NORTH
AS STEADIER RAIN DEVELOPS. GUSTY SOUTHERLY WINDS WILL ALSO DEVELOP
DURING THE AFTERNOON. EXPECT GUSTS TO AROUND 40 TO 45 KT FOR KAST
AND KONP...WITH 25 TO 30 KT GUSTS FOR THE INTERIOR TAF SITES AFTER
21Z WED.

KPDX AND APPROACHES...EXPECT MAINLY MVFR CONDITIONS OVERNIGHT. RAIN
TO INCREASE AGAIN AROUND 18Z WED WITH CONDITIONS LIKELY REMAINING AS
MVFR. GUSTY WINDS THROUGH THE GORGE STARTING AROUND 12Z WED WILL
IMPACT EASTERLY APPROACHES.

&&

.MARINE...WINDS WILL BE RELATIVELY LIGHT OVERNIGHT AS A WARM FRONT
APPROACHES FROM THE S. A RAPID INCREASE IN WINDS WILL COME DURING
THE MORNING HOURS SPREADING FROM S TO N AS A WARM FRONT LIFTS N
THROUGH THE COASTAL WATERS...ASSOCIATED WITH AN INTENSIFYING LOW
THAT WILL LIFT N OFF THE N OREGON AND WA COAST NEAR 130W LATE WED
AND WED NIGHT. EXPECT WINDS TO RAMP UP QUICKLY WED MORNING PEAKING
IN STORM CATEGORY WED AFTERNOON AND NIGHT. IN RESPONSE TO THE STORM
FORCE WINDS STEEP SEAS WILL BUILD QUICKLY WED AFTERNOON AND
EVENING...AND ARE EXPECTED TO TOP 25 FT WED NIGHT. WINDS WILL REMAIN
STRONG THROUGH MUCH OF THE NIGHT WED NIGHT BEFORE FINALLY SUBSIDING
THU MORNING BEHIND A COLD FRONT. AN ACTIVE WEATHER PATTERN CONTINUES
THROUGH THE UPCOMING WEEKEND.

SEAS WILL LIKELY REMAIN ABOVE 20 FT INTO THU...BEFORE GRADUALLY
SUBSIDING LATER THU. SEAS DROP BACK DOWN NEAR 10 FT BY LATE IN THE
WEEK...BUT ARE EXPECTED TO INCREASE AGAIN GOING INTO THE WEEKEND.

AN ADDITIONAL CONCERN WILL BE THE POTENTIAL FOR FLOODING OF LOW
LYING AREAS ALONG THE S WASHINGTON COAST WED DUE TO TIDAL OVERFLOW.
A HIGH ASTRONOMICAL HIGH TIDE NEAR 9.9 FT AROUND 2 AM LATE WED
NIGHT WILL COMBINE WITH FORECASTED SURGE PLUS TIDAL ANOMALY NEAR 2
FT...WHICH IS EXPECTED TO PUSH THE OVERALL WATER LEVEL TO NEAR 12 FT.
