Blizzard Warning 1, NWS Portland, OR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
904 AM PST THU DEC 11 2008

.SYNOPSIS...A MAJOR PATTERN SHIFT IS STILL ON TRACK TO BEGIN ON
FRIDAY...WITH A TRANSITION TO TEMPERATURES WELL BELOW NORMAL FOR THE
WEEKEND AND SNOW LIKELY DOWN TO THE INLAND VALLEY FLOORS BY SUNDAY.
SNOW OR MIXED RAIN AND SNOW WILL ALSO BE POSSIBLE DOWN TO THE BEACHES
BY SUNDAY. THE INITIAL COLD FRONT FRIDAY WILL ALSO BRING SIGNIFICANT
WIND TO THE AREA...ESPECIALLY TO THE COAST AND HIGHER TERRAIN. SEAS
WILL BUILD QUICKLY OFFSHORE...WITH HIGH SURF POUNDING THE COAST LATE
FRIDAY INTO SATURDAY. THE COMBINATION OF WIND AND HEAVY SNOW MAY
CAUSE BLIZZARD CONDITIONS AT TIMES IN THE CASCADES LATE FRIDAY AND
FRIDAY NIGHT. A COLD ARCTIC AIR MASS WILL LINGER ACROSS THE DISTRICT
WELL INTO NEXT WEEK...WITH TEMPERATURES STRUGGLING TO GET ABOVE
FREEZING.

&&

.SHORT TERM...A WEAK UPPER LEVEL TROUGH IS DRAGGING MAINLY MID/HIGH
LEVEL CLOUDS ACROSS OREGON THIS MORNING...WITH LITTLE TO NOTHING IN
THE WAY OF PRECIPITATION SHOWING UP ON RADAR ACROSS THE FORECAST
AREA. LOW CLOUDS AND PATCHY FOG LINGER IN THE INLAND VALLEYS AND
COAST RANGE THIS MORNING WITH PLENTY OF LOW LEVEL MOISTURE REMAINING
IN THE BOUNDARY LAYER. THE HIGH CLOUDS STREAMING OVERHEAD WILL LIKELY
SLOW THE BREAKUP OF THESE LOW CLOUDS TODAY...AND WITH LIGHT FLOW
ACROSS THE DISTRICT IT COULD WIND UP BEING A MAINLY CLOUDY DAY TODAY
FOR MOST OF THE INLAND VALLEYS. A LITTLE BIT OF NORTHERLY FLOW MAY
RESULT IN SOME PARTIAL CLEARING THIS AFTERNOON. TEMPERATURES NOT TOO
DIFFERENT FROM THOSE WEDNESDAY...NOT STRAYING TOO FAR AWAY FROM
SEASONAL NORMS.

FURTHER CLEARING TONIGHT WILL RESULT IN TEMPERATURES A COUPLE DEGREES
COOLER THAN LAST NIGHT...WITH FOG DEVELOPMENT SLIGHTLY MORE
WIDESPREAD. CURRENT FORECAST HANDLES THE PATTERN WELL THROUGH
TONIGHT...SO ANTICIPATE VERY FEW CHANGES THROUGH TONIGHT IN THE
MORNING UPDATE.

THEN A MAJOR CHANGE IN THE WEATHER PATTERN WILL BE USHERED IN BY A
VERY POTENT LOW PRESSURE SYSTEM AND ASSOCIATED COLD FRONT DUE OVER
THE AREA ON FRIDAY. LATEST MODELS HAVE BEEN TRENDING A LITTLE SLOWER
WITH THE TIMING OF THIS SYSTEM...AND A LITTLE FURTHER SOUTH WITH THE
PLACEMENT. WHEREAS WEDNESDAYS MODELS WERE SUGGESTING A 982-984 MB LOW
CENTERED NEAR THE STRAIT OF JUAN DE FUCA MIDDAY FRIDAY...NOW THE 12Z
GFS/NAM SHOW PRETTY GOOD AGREEMENT ON A 985 MB LOW CENTERED JUST
INLAND OF HOQUIAM AROUND 00Z SAT (LATE FRI AFTERNOON LOCAL TIME).
FRONTAL WINDS STILL LOOK STRONG WITH AN 850 MB FRONTAL JET OF 65-70
KT AS THE FRONT MOVES ONSHORE. WITH THE EXCELLENT DYNAMICS OF THIS
DEVELOPING SYSTEM...GUSTS OF THIS MAGNITUDE WILL LIKELY REACH DOWN TO
NEAR THE SURFACE ALONG THE COAST AND COAST RANGE...AND LIKELY IN THE
CASCADES AS WELL. HAVE EXPANDED THE HIGH WIND WATCHES TO COVER THE
COAST...COAST RANGE...WILLAPA HILLS AND NORTHERN OREGON/S WASHINGTON
CASCADES.

BEHIND THE FRONT...SHARPLY COLDER AIR WILL MOVE INTO THE DISTRICT.
SNOW LEVELS WILL CRASH DOWN FROM AROUND 7000 FEET AHEAD OF THE FRONT
FRIDAY MORNING TO AS LOW AS 500-1000 FEET BEHIND THE FRONT FRIDAY
NIGHT. STRONG OROGRAPHIC FLOW WILL CONTINUE OVER THE
CASCADES...FOOTHILLS AND COAST RANGE WELL INTO THE DAY SATURDAY.
THEREFORE 2-3 FEET OF SNOW AND OCCASIONAL BLIZZARD CONDITIONS STILL
LOOK REASONABLE FOR THE HIGH CASCADES...AND UPWARDS OF A FOOT OF SNOW
IS POSSIBLE IN THE COAST RANGE AND HIGHER CASCADE FOOTHILLS. BY LATE
FRIDAY NIGHT OR SATURDAY MORNING...SNOW WILL BECOME POSSIBLE FOR THE
LOWER INLAND HILLS... INCLUDING THE HILLS AROUND PORTLAND. AT THIS
POINT IT APPEARS STICKING SNOW THROUGH SATURDAY WILL BE MAINLY ABOVE
750-1000 FEET ELEVATION...THOUGH HEAVIER SHOWERS MAY BRIEFLY CAUSE A
DUSTING TO LOWER ELEVATIONS.

THE NEXT BIG CHALLENGE WILL BE THE POTENTIAL FOR ACCUMULATING SNOW
DOWN TO VERY LOW ELEVATIONS...POSSIBLY THE VALLEY FLOORS...AS THE
ARCTIC FRONT SLOWLY PRESSES SOUTHWARD THROUGH THE AREA. 12Z GFS/NAM
AND 00Z ECMWF ARE BEGINNING TO COME TOGETHER ON AN UPPER LOW JUST OFF
THE COAST SLIDING SOUTHWARD DURING THE DAY SUNDAY. MEANWHILE ARCTIC
AIR WILL BE WEDGING DOWN THE EAST SIDE OF THE CASCADES WITH A DECENT
EASTERLY GORGE WIND BEGINNING TO ALLOW THE COLDER AIR INTO THE WEST
GORGE AND NORTH WILLAMETTE VALLEY. AT THIS POINT...IT APPEARS SUNDAY
WILL BE COLD ENOUGH FOR SNOW DOWN TO VALLEY FLOORS...BUT IT ALL
DEPENDS ON HOW MUCH MOISTURE PULLS INTO THE DISTRICT SUNDAY. AT THIS
POINT SNOW LIKELY LOOKS LIKE A GOOD FORECAST...AND THE POSSIBILITY OF
STICKING SNOW IN AT LEAST THE NORTH WILLAMETTE VALLEY IS STARTING TO
LOOK A LITTLE STRONGER NOW THAT THE 12Z GFS IS COMING BACK IN LINE
WITH THE NAM/EC WITH THE UPPER AND SURFACE LOWS TRACKING CLOSER TO
THE COAST ON SUNDAY.  WEAGLE

.LONG TERM...ON SUNDAY AFTERNOON THE MODIFIED ARCTIC BOUNDARY AT THE
EDGE OF THE FIRST PUSH OF CHILLY AIR WILL RUN FROM A SURFACE LOW
ANCHORED WEST OF VANCOUVER ISLAND TO THE SSE JUST OFFSHORE OF THE
WASHINGTON COAST THROUGH NW OREGON AND THEN INLAND AND EAST ACROSS
THE NORTH CENTRAL OREGON CASCADES.  WITH THE BOUNDARY IN THIS
POSITION WAVES RIPPLING ALONG IT WILL CONTINUE TO BRING SNOW SUNDAY
NIGHT AND EARLY MONDAY MORNING.

ON MONDAY THE UPPER LEVEL RIDGE OVER INTERIOR ALASKA AND THE YUKON
TERRITORY WILL BEGIN TILTING EAST AND SINKING SOUTH INTO BRITISH
COLUMBIA. IN RESPONSE THE COLD UPPER TROUGH OVER THE PACIFIC
NORTHWEST WILL ALSO DROP A BIT FURTHER SOUTH. AT THE SURFACE...HIGH
PRESSURE BUILDING IN INTERIOR BRITISH COLUMBIA WILL INTENSIFY AND
SHIFT INTO SOUTHERN BRITISH COLUMBIA. THIS VERY COLD AREA OF HIGH
PRESSURE WILL CONTINUE TO EXPAND SOUTHWARD MOVING INTO EASTERN
WASHINGTON MONDAY NIGHT AND TUESDAY MARKING THE ARRIVAL OF THE
REALLY COLD ARCTIC AIR MASS.

THE MODIFIED ARCTIC BOUNDARY WHICH HAD BEEN STALLED OVER NW CORNER
OF OREGON WILL DROP SOUTH OF OUR CWA AS COLD OFFSHORE FLOW AND EAST
WINDS INCREASE RAPIDLY. SNOW SHOWERS WILL TAPER OFF EARLY MONDAY
BRINGING DRY BUT COLD WEATHER THROUGH WEDNESDAY. ANOTHER UPPER LEVEL
TROUGH WILL DIVE DOWN FROM THE NORTH ON WEDNESDAY AFTERNOON AND
THURSDAY REPLENISHING OUR SUPPLY OF ARCTIC AIR.  DEPENDING ON THE
TRACK OF THIS LOW IT COULD POTENTIALLY BRING SNOW BUT CURRENTLY THE
MODELS ARE STICKING WITH A DRIER INTERIOR TRACK STRAIGHT OUT OF THE
NORTH. RUTHFORD

&&

.AVIATION...OFFSHORE FLOW SLOW TO DEVELOP THIS MORNING. AS A
RESULT...IFR CEILINGS CONTINUE TO HANG TOUGH ACROSS THE INTERIOR.
CONDITIONS SHOULD IMPROVE TO VFR BY THIS AFTERNOON AS HEIGHTS BUILD
AND THE OFFSHORE FLOW INCREASES. WILL NEED TO WATCH FOR FOG TO
RE-FORM AFTER 04Z FRI OR SO DUE TO WEAK LOW LEVEL GRADIENTS.

KPDX AND APPROACHES...IFR CEILINGS WILL CONTINUE ACROSS ALL
APPROACHES UNTIL 19Z. OFFSHORE FLOW SHOULD BE ABLE TO BREAK UP THE
STRATUS WHEN THIS OCCURS AND RETURN CONDITIONS TO VFR.

&&

.MARINE...PLENTY OF MARINE ISSUES IN THE NEXT 48 HOURS.
CURRENTLY...SEAS RUNNING NEAR 10 FT AND SHOULD CONTINUE TODAY.
EXTREMELY HIGH TIDE TODAY (11.1 FEET AT TOKE POINT) WILL RESULT IN
THE POSSIBILITY OF MINOR TIDAL OVERFLOW FOR THE S WASHINGTON COAST.

MODELS COMING INTO DECENT AGREEMENT WITH STRENGTH AND TRACK OF THE
STRONG LOW FOR FRI. STILL LOOKS LIKE THE LOW CENTER GETS TO THE N
WASHINGTON COAST AROUND 00Z SAT. LOOKS LIKE N WATERS HAVE A DECENT
SHOT OF STORM FORCE WIND GUSTS...ESPECIALLY WITH AND JUST BEHIND THE
FRONT. WILL MAINTAIN THE STORM WARNING FOR THE N WATERS FROM 18Z FRI
THROUGH 06Z SAT. STRONG GALE SHOULD FOLLOW FOR AT LEAST 12 HOURS
MORE. S WATERS DO NOT APPEAR TO MAKE STORM FORCE...BUT WILL HAVE
SOLID GALE 18Z FRI THROUGH 18Z SAT.

SEAS WILL BUILD RAPIDLY FRI. EXPECT FIRST 20-FOOT SEAS TO IMPACT THE
SURF ZONE BETWEEN 00Z AND 06Z SAT. WAVE WATCH AND THE ENP MODELS
STILL INDICATING PEAK SEAS BETWEEN 25 AND 28 FEET FRI NIGHT THROUGH
SAT. THE SWELL WILL HAVE A NORTHWEST COMPONENT...WHICH WILL REDUCE
THE TOTAL ENERGY IMPACTING THE BEACHES. HOWEVER...THE POSSIBILITY
EXISTS FOR HIGH SURF WARNING CONDITIONS OR COASTAL FLOODING DURING
THIS TIME. WILL LIKELY ISSUE A COASTAL FLOOD WATCH FOR THIS IN THE
AFTERNOON.

...ARCTIC AIR OVER SOUTHWEST WASHINGTON AND NORTHWEST OREGON
SUNDAY AND NEXT WEEK WITH SOME SNOW POSSIBLE AT TIMES NEXT WEEK...

AFTER THE STRONG STORM FROM FRIDAY AND SATURDAY MOVES THROUGH...
ARCTIC AIR WILL SPILL INTO SOUTHWEST WASHINGTON AND NORTHWEST
OREGON SUNDAY...AND CONTINUE OVER THE AREA FOR AT LEAST A GOOD
PART OF NEXT WEEK. THIS WILL LIKELY BE THE COLDEST WEATHER IN MUCH
OF SOUTHWEST WASHINGTON AND NORTHWEST OREGON SINCE AT LEAST 2004.
DAYTIME TEMPERATURES WILL FALL INTO THE 20S ON SUNDAY MAINLY IN
THE NORTH AS THE ARCTIC AIR SPREADS IN. THE ARCTIC AIR WILL LIKELY
REACH THE SOUTHERN WILLAMETTE VALLEY AREA SUNDAY NIGHT AND
MONDAY. DAYTIME HIGHS WILL THEN STRUGGLE TO REACH FREEZING THROUGH
MUCH OF NEXT WEEK. NIGHTTIME LOWS WILL DROP INTO AT LEAST THE
TEENS...WITH SINGLE DIGITS OR POSSIBLY EVEN BELOW ZERO IN THE
CASCADES.

SOME MOISTURE MAY STILL BE CIRCULATING AROUND AN UPPER LOW NEAR
THE COAST ON SUNDAY AND MONDAY THAT COULD PRODUCE SNOW OVER MUCH
OF THE AREA. ACCUMULATIONS ARE UNCERTAIN AT THIS POINT...BUT
SIGNIFICANT ACCUMULATIONS ARE POSSIBLE IN SOME AREAS.

THE ARCTIC AIR WILL PRODUCE STRONG EAST WINDS THROUGH THE COLUMBIA
RIVER GORGE AND OVER THE MOUNTAINS SUNDAY THROUGH ABOUT TUESDAY.
THIS COULD DROP WIND CHILLS IN SOME AREAS TO BELOW ZERO OR EVEN
AROUND 10 BELOW ZERO...ESPECIALLY IN THE COLUMBIA RIVER GORGE AND
POSSIBLY IN THE CASCADES.

THERE IS A POSSIBILITY OF ANOTHER SYSTEM IN THE MIDDLE PART OF
NEXT WEEK THAT COULD BRING MORE SNOW TO THE AREA AS THE AIR MASS
OVER SOUTHWEST WASHINGTON AND NORTHWEST OREGON REMAINS COLD.
