AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
257 AM PDT WED MAR 20 2013

.SYNOPSIS...A LOW PRES SYSTEM MOVING ONTO VANCOUVER ISLAND TODAY
WILL PUSH A COLD FRONT THROUGH THE REGION THIS MORNING. THIS WILL
SET UP A COOL AND UNSTABLE NW FLOW OVER THE PACIFIC NW THAT WILL
LAST THROUGH MOST OF THE WEEK...RESULTING IN SHOWERY WEATHER WITH
LOW SNOW LEVELS.

&&

.SHORT TERM...COLD FRONT STILL OUT PAST BUOY 46089 EARLY THIS
MORNING...EXPECTED TO PUSH INLAND THIS MORNING AS A SHORTWAVE SEEN
IN WATER VAPOR PICTURES APPROACHING 130W...PROGRESSES E. SURFACE
OBSERVATIONS AND RADAR SHOW AREAS OF LIGHT RAIN CONTINUING AHEAD OF
THE FRONT IN THE AREA OF DEEP MOISTUTE. PRECIPITATION HOWEVER
EXPECTED TO TRANSITION OVER TO A CONVECTIVE REGIME BEHIND THE FRONT
AS COOLER AIR MOVES IN. PEAK WIND GUSTS ALONG THE COAST EARLY THIS
MORNING GENERALLY RUNNING IN THE 50 TO 60 MPH RANGE...AND WILL
DIMINISH SOME ONCE THE FRONT MOVES THROUGH. INLAND HOWEVER...THE
FRONT WILL BRING SOME STRONGER GUSTS AS SURFACE PRES GRADIENTS
ORIENT N TO S THROUGH THE VALLEY WITH PEAK GRADIENTS REACHING
AROUND 6 MB. UW MESOSCALE MODELS SUGGEST PEAK GUSTS ON THE ORDER OF
40 MPH IN THE WILLAMETTE VALLEY TODAY.

BUFR SOUNDINGS FOR LATE TODAY SUGGEST ENOUGH INSTABILITY TO KEEP A
MENTION OF THUNDER AND SMALL HAIL IN. A FAIRLY STRONG WESTERLY FLOW
AT 850 MB FOLLOWS THE FRONT...AND SLOWLY WEAKENS OVERNIGHT. AIR MASS
BEHIND THE FRONT REMAINS MOIST BELOW 700 MB...WHICH COUPLED WITH
GOOD OROGRAPHICS AND INSTABILITY SUGGEST A PRETTY GOOD PERIOD OF
SNOWFALL FOR THE CASCADES...ESP IN THE N. SHORTWAVES AROUND MIDDAY
TODAY...AND AGAIN THIS EVENING WILL PROVIDE ADDITIONAL LIFT. AS SUCH
WILL MAINTAIN THE WINTER WEATHER HEADLINES FOR THE N OREGON AND S WA
CASCADES. AS SNOW LEVELS FALL TONIGHT...OROGRAPHICS WEAKEN...SO IT
IS NOT CLEAR THAT WINTER WEATHER ADVISORIES WOULD BE NEEDED FOR ANY
OF THE FOOTHILLS OR COAST RANGE.

ONSHORE CONTINUES TO SLOWLY WEAKEN THU AND FRI...WHILE SUBSIDENCE
INVERSION SLOWLY LOWERS TO DECREASE INSTABILITY. WILL KEEP A TREND
FOR DECREASING CHANCES FOR SHOWERS THROUGH THIS PERIOD.

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS.
FRI NIGHT THROUGH THU...THE LONG TERM MODELS ARE BEGINNING TO COME
INTO BETTER AGREEMENT FOR THE UPCOMING WEEKEND. A DEEP BROAD TROUGH
WILL DIG IN OVER THE ROCKIES AND GREAT PLAINS. MEANWHILE AN UPPER
LEVEL RIDGE WILL SIT OVER THE NE PAC. THE PAC NW REMAINS IN
BETWEEN...WITH PREVAILING NORTH/NORTHWEST FLOW. THE MODELS SHOW
MOISTURE RIDING DOWN THE BACKSIDE OF THE RIDGE... KEEPING US IN A
CLOUDY AND COOL PATTERN. WITH THE MOISTURE COMING OVER THE
RIDGE...THE CHANCE WILL BE THERE FOR SOME DRIZZLE OR BRIEF SHOWER
FROM TIME TO TIME. BUT NOTHING ORGANIZED IS EXPECTED. HEADING INTO
EARLY NEXT WEEK...IT APPEARS THAT NE PAC RIDGING WILL BEGIN TO PUSH
ONSHORE. THIS SHOULD DRY US OUT FOR A COUPLE OF DAYS AND WARM TEMPS
BACK TO NEAR SEASONAL NORMALS. PYLE

&&

.AVIATION...WARM FRONT HAS CLEARED THE SOUTH VALLEY ALLOWING FOR A
BRIEF RETURN TO VFR. MOSTLY MVFR ELSEHWERE....WITH THE STRONGEST
WINDS ONGOING AT THE COAST NOW...AND PICKING UP IN THE VALLEY IN THE
NEXT FEW HOURS. MOST AREAS IN THE VALLEY ARE SHIFTING TO SOUTH
WIND...WITH THE EXCEPTION BEING NEAR THE GORGE WHERE EAST WINDS WILL
HANG ON A BIT LONGER. THEREFORE...STILL A FEW MORE HOURS OF LOW
LEVEL WIND SHEAR AT THE WEST END OF THE GORGE. EXPECT WIDESPREAD
MVFR MIXED WITH IFR AS COLD FRONTAL RAIN QUICKLY RETURNS.

COLD FRONT WILL PUSH ONSHORE AROUND 14-15Z...AND AN HOUR OR TWO
LATER INLAND. STEADY RAIN WILL TURN TO SHOWERS BY NOON...AND WITH
COLD AIR ALOFT EXPECT HAIL SHOWERS AND ISOLATED TSTORMS. BREEZY W
WINDS OVER THE CASCADES WITH GUSTS OVER 45 KT THROUGH THE DAY.

KPDX AND APPROACHES...MVFR CONDITIONS CONTINUE THIS MORNING. EAST
WINDS CONTINUE TO 11 OR 12Z...WITH LOW LEVEL WIND SHEAR DUE TO
SOUTH WINDS 30 TO 45 KT AT AND ABOVE 1500 FEET AGL. WINDS WILL
FINALLY TURN S AS FRONT DRAWS CLOSER..AND THEN SURFACE COLD FRONT
ARRIVES AROUND 17Z...SHIFTING WINDS TO WSW. KMD

&&

.MARINE...SOLID GALES OVER THE WATERS EARLY THIS MORNING AS A
STILL DEEPENING 984 MB SURFACE LOW IS BEING SAMPLED BY SHIPS/BUOYS
OFF THE TIP OF VANCOUVER ISLAND. THE WARM FRONT HAS CLEARED...AND
NOW A WIND SHIFT FRONT IS TO BE QUICKLY FOLLOWED BY THE TRUE COLD
FRONT LATER THIS MORNING. BEHIND THE COLD FRONT...STILL LOOKS LIKE
DECENT CHANCE FOR GALE FORCE WINDS SPREADING BACK INTO THE WATERS
AFTER A BRIEF LULL...ESPECIALLY IN THE NORTHERN WATERS THAT ARE
CLOSER TO THE DEPARTING LOW. BUOY 2...WELL OFF THE SOUTHERN OREGON
COAST AND NOW BEHIND THE COLD FRONT IS NOW BACK UP TO GUSTS 35
KT...SO EVEN A PERIOD OF GALES POSSIBLE IN THE CENTRAL WATERS AS
WELL. WINDS WILL GRADUALLY EASE LATER WED AND WED NIGHT...AND HAVE
THEREFORE MAINTAINED CURRENT GALE EXPIRATIONS OF MIDDAY IN THE
CENTRAL WATERS...LATE AFTERNOON IN THE NORTH.

WIND GENERATED WAVES NOW 15 TO 20 FT...HIGHEST IN THE CENTRAL
OREGON WATERS WHERE BEST FETCH HAS BEEN. EXPECT BRIEF LET UP AS
WINDS EASE...BUT W SWELL FETCH ARRIVES IN THE AFTERNOON. THIS
KEEPS SEAS AT 18 TO 20 FT ON N COASTAL WATERS ... AND 15 TO 17 FT
TO THE S...FOR LATE WED AFTERNOON AND WED NIGHT. SEAS WILL
GRADUALLY SUBSIDE ON THU.

HIGH PRES WILL SLOWLY BUILD OVER THE REGION LATER IN THE WEEK
AND INTO THE WEEKEND...WHICH SHOULD BRING A RESPITE FROM THE RECENT
ACTIVE WEATHER...THOUGH THERE WILL BE ENOUGH GRADIENT TO SUPPORT
NW WINDS 20-25 KT THROUGH FRIDAY MORNING...AND SEAS LINGERING
ABOVE 10 FT. MUCH CALMER OVER THE WEEKEND. KMD
