AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
245 AM PST SUN DEC 16 2012

.SYNOPSIS...A WARM FRONT WILL LIFT NE THROUGH THE REGION
TODAY...FOLLOWED BY A COLD FRONT THIS EVENING. THE FRONTS ARE
ASSOCIATED WITH A DEEP LOW PRESSURE SYSTEM THAT WILL APPROACH THE WA
COAST LATE TONIGHT...AND MOVE INLAND OVER PUGET SOUND EARLY MON. AN
UPPER TROUGH WILL LINGER OVER THE PACIFIC NW THROUGH TUE KEEPING A
COOL UNSTABLE AIR MASS OVER THE REGION. THE NEXT PACIFIC STORM
SYSTEM WILL MOVE INTO THE PACIFIC NW MIDWEEK.

&&

.SHORT TERM...RADAR SHOWED SCATTERED SHOWERS CONTINUED EARLY SUN
MORNING ACROSS THE FORECAST AREA. WARM AIR ADVECTION WILL KICK INTO
LATER THIS MORNING...BRINGING MOIST ISENTROPIC LIFT THAT SHOULD
SPREAD PRECIPITATION TO MOST OF THE AREA BY MIDDAY. GFS AND ECMWF
SEEM TO HAVE SETTLED ON A COMMON SOLUTION OF DEEPING A LOW AS IT
APPROACHES THE WA COAST TONIGHT...AND BRINGING A SUB 980MB LOW
INLAND NEAR THE OLYMPIC PENINSULA AROUND 12Z MON ON AN E MOVING
TRACK. WITH THE CONSISTENCY SHOWN IN THE TWO MODELS...CONFIDENCE IN
THE MAIN ASPECTS OF THE FORECAST CONTINUES TO RISE.

OVERALL THIS SYSTEM PACKS A VERY STRONG WIND FIELD...FROM A 150KT
JET POKING INTO OREGON TONIGHT...TO GFS DEPICTED 950 MB WINDS
REACHING 70 KT OVER THE COASTAL WATERS LATE TODAY AND TONIGHT. THE
HIGH WIND THREAT TO THE COAST BEGINS WITH THE SOUTH WINDS ARRIVING
WITH THE WARM OR OCCLUDED FRONT THIS AFTERNOON...AND CONTINUES
OVERNIGHT INTO MON MORNING AS A WRAP AROUND OCCLUSION PUSHES ONTO
THE N OREGON AND S WA COAST. AS WINDS SWITCH FROM THE S EARLY ON TO
THE W WITH THE WRAP AROUND OCCLUSION...THE IMPACTS FROM THE HIGH
WINDS WILL AFFECT LOCATIONS NOT ACCUSTOMED TO THE NORMAL SOUTHERLY
HIGH WINDS.

WITH THE STRONG WIND FIELD AND THE SURFACE LOW CROSSING NW WA...THE
POTENTIAL FOR STRONG WINDS EXTENDS INLAND. SURFACE PRESSURE
GRADIENTS SUGGEST PEAK GUSTS IN THE WILLAMETTE VALLEY TOPPING 50 MPH
LATE TONIGHT AND EARLY MON. WITH WET GROUND...AND THE FACT THAT ITS
BEEN A WHILE SINCE WE LAST HAD STRONG WIDESPREAD S WINDS IN THE
VALLEY...BELIEVE THE POTENTIAL FOR WIND DAMAGE TO TREES IS HIGHER
THAN IT MIGHT NORMALLY BE WITH 50 PLUS MPH WINDS...SO PLAN ON GOING
WITH A WARNING FOR THE NORTHERN PART OF THE INLAND ZONES TONIGHT
INTO MON MORNING.

ISENTROPIC LIFT TODAY...FOLLOWED BY STRONG DYNAMIC LIFT ASSOICATED
WITH THE UPPER LEVEL TROUGH AND JET...COUPLES WITH DEEP MOISTURE AND
STRONG OROGRAPHICS TO PROMISE AN INTENSE PERIOD OF SNOWFALL IN THE
CASCADES THIS AFTERNOON INTO MON...ESP THIS EVENING. FLUCTUATING
SNOW LEVELS...ESP THIS AFTERNOON AND EVENING...MAKE PINNING DOWN
SNOW TOTALS AT SPECIFIC ELEVATIONS A BIT MORE OF A CHALLENGE THAN
USUAL. MAY SEE A BRIEF PERIOD LATE TODAY WHERE SNOW LEVELS RISE AS
HIGH AS 6K FT IN THE S PART OF THE CASCADES AS THE WARM FRONT MOVES
THROUGH...BUT COLDER AIR FOLLOWING A FEW HOURS LATER SHOULD LIMIT
THE TIME THE MOUNTAIN PASSES SPEND BELOW SNOW LEVELS TO JUST A FEW
HOURS. THE STRONG WINDS ALSO SUGGEST BLOWING SNOW LIKELY TO BE AN
ISSUE AT EXPOSED LOCATIONS.

THE REMAINDER OF THE SHORT TERM...LATER MON THROUGH TUE WILL SEE A
MOIST ONSHORE FLOW PERSISTING BUT SLOWLY WEAKENING AS AN UPPER
TROUGH REMAINS OVER THE REGION. BOTH NAM AND GFS BUFR SOUNDINGS
SUGGEST LOW SNOW LEVELS AGAIN LATE MON NIGHT AND EARLY TUE. WHILE
POPS WILL REMAIN HIGH INTO TUE IN THE SHOWERY PATTERN...A LACK OF
FOCUSING MECHANISM...THE POSSIBILITY OF A RAIN SHADOW IN THE WNW
FLOW...AND TEMP FIELDS SUGGESTING SURFACE TEMPS NEAR OR A LITTLE
ABOVE FREEZING OVERALL SUGGESTS LIMITED POTENTIAL FOR SIGNIFICANT
STICKING SNOW AT LOW ELEVATIONS.

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS.
MONDAY EVENING THROUGH FRIDAY...A DEPARTING SHORTWAVE LATE MONDAY
WILL MAKE WAY FOR THE NEXT COLD UPPER LEVEL TROUGH BY EARLY TUESDAY.
MODELS ARE IN GOOD AGREEMENT CONCERNING THE TIMING AND STRENGTH OF
THIS TROUGH...WHICH SHOULD LOWER SNOW LEVELS WELL BELOW 1000 FT AND
KEEP LOWS MOSTLY IN THE MID 30S...MAKING TUESDAY THE COLDEST DAY OF
THE EXTENDED PERIOD. THIS IS A FAST MOVING TROUGH AND WILL BE
QUICKLY REPLACED BY A SHORTWAVE RIDGE EARLY WEDNESDAY MORNING.
SHOWERS WILL PERSIST DESPITE THE RIDGING. A LARGE UPPER LOW WILL
DROP SOUTH FROM THE GULF OF ALASKA LATE WEDNESDAY AND BECOME NEARLY
STATIONARY JUST OFF THE PACIFIC NW COAST BY THURSDAY... CONTINUING
THE ADVECTION OF MOISTURE INTO THE PAC NW THROUGH LATE NEXT WEEK. /27

&&

.AVIATION...POST-FRONTAL UNSTABLE AIR MASS OVER SW WA AND NW OREGON
WILL MAINTAIN GENERALLY VFR CONDITIONS WITH AREAS OF
MVFR...ESPECIALLY OVER THE COAST RANGE AND CASCADES. EXPECT MOUNTAIN
OBSCUREMENT AS WELL DUE TO THE OROGRAHIC SHOWERS. AIR MASS WILL
STABILIZE AFTER 12Z SUN AS A WARM FRONT APPROACHES THE COAST.
CONDITIONS WILL LOWER TO MVFR ALONG THE COAST AROUND 18Z AND INLAND
BY 20Z. EXPECT IFR TO MVFR AFTER 20Z AS RAIN AND WIND INCREASE.
COASTAL SITES LIKELY TO GET WIND GUSTS OF 45 KT OR MORE LATE SUN
AFTERNOON THRU SUN NIGHT. INTERIOR VALLEYS SHOULD GET GUSTS 35-45 KT
00Z MON THRU 18Z MON. SOUTH WA AND N OREGON COAST MAY GET A ONE-TWO
WIND PUNCH. THE FIRST SURGE WILL BE THE WARM-FRONTAL SOUTH WIND SUN
EVENING...THEN ANOTHER POTENTIALLY STRONGER SURGE LATE SUN NIGHT AND
MON MORNING AS THE LOW SWINGS INLAND OVER NW WA.

KPDX AND APPROACHES...VFR THROUGH AT LEAST 15Z SUN IN THE POST-
FRONTAL UNSTABLE AIR MASS. HOWEVER...CONDITIONS WILL DETERIORATE
AFTER 18Z SUN AS WARM-FRONTAL PRECIPITATION DEVELOPS. E-SE SURFACE
WIND THROUGH ABOUT 00Z MON...BUT WITH VERY STRONG SOUTH WIND 2000
TO 3000 FEET ABOVE THE SURFACE. HIGH POTENTIAL FOR LOW-LEVEL WIND
SHEAR AT KPDX AND KTTD THIS AFTERNOON. WIND GUSTS 35-50 KT
POSSIBLE THIS EVENING THROUGH EARLY MON MORNING. WEISHAAR

&&

.MARINE...A BRIEF LULL IN THE WIND AND SEAS THROUGH THIS
MORNING...BUT THEN BIG CHANGES ARE IN STORE LATER SUNDAY THROUGH
MON.

ATTENTION TURNS TO A DEVELOPING LOW WELL OFFSHORE. THIS LOW WILL
DEEPEN RAPIDLY SUN.. NAM AND GFS INDICATE A NEAR 980 MB SURFACE
LOW NEAR 47N 135W AT 18Z...AND THEN NEAR 975 MB OR EVEN A LITTLE
DEEPER AT OR INSIDE 130W 00Z MON. GFS IS DEEPER BUT A LITTLE
SLOWER THAN THE NAM. IN ANY EVENT...HIGH CONFIDENCE THAT STORM
FORCE WIND WILL BE GENERATED. IN ADDITION...MODELS SUGGEST A
COASTAL JET FORMATION LATE THIS AFTERNOON THROUGH ABOUT MIDNIGHT.
COULD SEE SUSTAINED 50 KT WITH GUSTS UP TO 65 KT OVER THE INNER
WATERS...INCLUDING THE COLUMBIA RIVER BAR ENTRANCE.

LOW MAKES LANDFALL SOMEWHERE OVER NW WASHINGTON BETWEEN 06Z AND
10Z WITH THE NAM BEING THE SOONEST. THE LOW IS WEAKENING AS IT
MOVES ASHORE. THE WIND MAY EASE JUST A BIT LATE SUN EVENING AND
OVERNIGHT...BUT THERE IS A THREAT OF A SWLY WIND SURGE AS THE
OCCLUDED FRONT MOVES THROUGH THE S WA AND N OREGON WATERS. THIS
SURGE WOULD OCCUR FROM ABOUT 10Z THROUGH 16Z MON. BASED ON MODEL
TIMING DIFFERENCES...OPTED TO EXTEND THE STORM WARNING THROUGH 18Z
SHOULD THE SLOWER GFS TIMING VERIFY.

SEAS WILL BUILD RAPIDLY...WITH 15-20 FOOT WIND WAVE COMPONENT
POSSIBLE LATE SUN AFTERNOON THROUGH SUN EVENING. LATEST ENP NOT
QUITE AS HIGH AS THE PREVIOUS RUN...BUT STILL GOING WITH 25 TO 30
FT WAVE HEIGHTS BY 12Z MON. IF FORECAST WIND SPEEDS VERIFY...MODEL
MAY NOT BE GENERATING WIND WAVES FAST ENOUGH...ESPECIALLY IF A
COASTAL JET FORMS. SEAS WILL BE MORE WIND-WAVE THAN TRUE SWELL
LATE SUN AFTERNOON AND EVENING. THUS...NOT EXPECTING HIGH-SURF
CRITERIA TO BE MET THROUGH 06Z MON. HOWEVER...SWELL COMPONENT
BECOMES MORE DOMINANT AFTER 06Z MON AND WILL LIKELY EXCEED HIGH
SURF WARNING CRITERIA BY 12Z MON. A QUICK CHECK ON POTENTIAL
COASTAL FLOODING DID NOT REACH CRITERIA BASED ON THE LOCAL COASTAL
FLOOD INDEX GUIDANCE. EVEN WITH 30 FT SEAS AT 14 SECONDS...HIGH
TIDE OF 9 FT WITH A 3 FOOT ANOMALY...THE CFI BARELY MEETS
CRITERIA. EXPECTING A 1-2 FOOT ANOMALY. WEISHAAR.
