AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
327 AM PST WED NOV 12 2008

UPDATED FOR AVIATION DISCUSSION

.SHORT TERM...TODAY THROUGH THURSDAY...STRONG WESTERLY FLOW TO
CONTINUE THROUGH THIS EVENING...THEN THIS FLOW WILL TURN NORTHWEST
AS AN UPPER RIDGE AMPLIFIES ALONG 130W LATE TONIGHT AND THURSDAY.
MAIN MOISTURE PLUME HAS ALREADY STARTED TO SHOW SIGNS OF SHIFTING
NORTH DUE TO THE FIRST NUDGES OF THE EXPECTED BUILDING RIDGE. STILL
WESTERLY ONSHORE FLOW SHOULD KEEP GOOD CHANCES OF RAIN GOING
TODAY...ESPECIALLY NEAR AND JUST EAST OF THE CASCADE CREST AND ALONG
WEST FACING SLOPES OF THE INTERIOR NORTHWEST MOUNTAINS. BIGGER
PROBLEM TODAY WILL BE WINDS. WINDS AT 4000-6000 FEET ARE RUNNING
40-45 KTS AT THE MOMENT AND MODELS INDICATE THAT THE WINDS AT THIS
LEVEL COULD INCREASE TO 50-60 KTS TODAY. SURFACE GRADIENTS WILL BE
TIGHT BUT THE GRADIENT WILL GENERALLY BE SOUTH TO NORTH. THE
GRADIENT WILL THUS BE PARALLEL TO THE 850 MB WIND DIRECTION WHICH
SHOULD LIMIT THE DOWNWARD MOMENTUM OF THE WINDS AND REDUCE SURFACE
SPEEDS SOME. STILL MANY AREAS WILL SEE GUSTY SURFACE WINDS OF 30-40
MPH AND ISSUED WIND ADVISORIES WILL CONTINUE. A STRONG GRADIENT
EARLY THIS MORNING ACROSS SOUTHERN UNION COUNTY HAS BEEN CAUSING
WINDS IN THE LADD AND PYLES CANYONS TO RUN 30-40 MPH. THESE WINDS
ARE EXPECTED TO CONTINUE UNTIL LATE MORNING AND AN ADVISORY WAS
RAISED AROUND MIDNIGHT. WILL ALSO BE MONITORING WINDS OVER THE
NORTHERN BLUE MOUNTAINS. AT THIS TIME A 30-40 MPH FORECAST IS
HOLDING...BUT IF THERE IS A NOTICEABLE INCREASE WILL ISSUE A HIGH
WIND WARNING FOR THIS AREA. THESE STRONG WINDS WILL PERSIST INTO THE
EVENING...AND FOR A FEW LOCATIONS (THE COLUMBIA RIVER GORGE AND THE
KITTITAS VALLEY) THE WINDS MAY REACH THEIR PEAK AS GRADIENTS SHOULD
BECOME MORE WEST-EAST.

A SLOW MOVING...BUT WEAK COLD FRONT MOVES ACROSS THE REGION TONIGHT
KEEPING CHANCES OF PRECIP HIGH. SNOW LEVELS WILL SLOWLY FALL
TONIGHT...BUT WILL ONLY LOWER DOWN TO 4000-4500 FEET ACROSS SOUTHERN
WASHINGTON AT THEIR LOWEST. CONDITIONS SHOULD BEGIN TO DRY OUT...
WITH ONLY ISOLATED TO SCATTERED SHOWERS...THURSDAY DUE TO THE FINAL
DEPARTURE OF THE WEAK COLD FRONT AND THE NORTHWEST FLOW ALOFT. 90

.LONG TERM...THURSDAY NIGHT THROUGH SATURDAY...GFS AND NAM MODELS
ARE IN GOOD AGREEMENT FOR THIS TIME WITH SLIGHT DIFFERENCES. HOWEVER
GFS SEEMS TO BE THE FAVORED MODEL OF CHOICE LATELY. WINDS WILL DIE
DOWN AS THE TIGHT SURFACE GRADIENT PUSHES OFF TO THE EAST THURSDAY
EVENING. A RIDGE OF HIGH PRESSURE WILL BUILD IN FRIDAY. THE NAM
MODEL SUGGEST A SLIGHTLY SLOWER PROGRESSION OF THE RIDGE. IF THIS
TURNS OUT TO BE THE CASE THE WINDS MAY LINGER A BIT LONGER EAST OF
THE FOOTHILLS OF THE BLUE MOUNTAINS INTO EARLY FRIDAY MORNING. THIS
MAY AFFECT THE HIGH TEMPERATURE MAKING IT A BIT COOLER THAN CURRENT
FORECAST HOLDS FOR FRIDAY. LEANING TOWARDS GFS SOLUTIONS WILL
PROVIDE UNSEASONABLY WARM TEMPERATURES FRIDAY AND SATURDAY WITH THE
FASTER PROGRESSION OF THE RIDGE. PATCHY FOG WILL BE A CONCERN FOR
THE COLUMBIA RIVER GORGE...LOWER COLUMBIA BASIN...AND THE YAKIMA
VALLEY IN THE MORNINGS. MODEL SOUNDINGS INDICATE INVERSIONS SETTING
IN PLACE FRIDAY MORNING...WHICH WILL HELP AID IN FOG IF THE RHS GET
HIGH ENOUGH. WEBER

SATURDAY NIGHT THROUGH TUESDAY...00Z RUNS OF THE MEDIUM RANGE MODELS
ARE INDICATING AN AMPLIFIED PROGRESSIVE FLOW FROM THE LATTER HALF OF
THE WEEKEND THROUGH THE MIDDLE OF NEXT WEEK. MOST OF THE SHORT WAVES
APPEAR TO REMAIN NORTH OF THE AREA BUT ENOUGH UNCERTAINTY REMAIN
SUCH THAT CHANGES IN THE EXTENDED WERE NOT WARRANTED AT THIS TIME.
OPERATIONAL MODELS AND A MAJORITY OF ENSEMBLE MEMBERS SHOW SOME FORM
OF SHORTWAVE CLIPPING NORTHEASTERN WASHINGTON SATURDAY NIGHT WHICH
COULD BRING SOME LIGHT RAIN TO THE WASHINGTON CASCADES AND HIGHER
ELEVATIONS OF NORTHEASTERN OREGON. RIDGING THEN CROSSES THE AREA
THROUGH MOST OF MONDAY FOR WHAT WILL LIKELY BE DRY CONDITIONS.
ANOTHER SHORTWAVE, ALBEIT STRONGER AND DEEPER, CROSSES MONDAY NIGHT
AND TUESDAY PER THE OPERATIONAL GFS WHILE THE ECMWF HAS A STRONGER
SOLUTION AMPLIFYING OFFSHORE AND BRINGING IT ACROSS SLOWER THROUGH
WEDNESDAY. AGREE WITH EXISTING FORECAST FOR VALLEY AND BASIN FOG
NEARLY EVERY NIGHT/MORNING. GIVEN POTENTIAL FOR LIGHT WINDS AND
OTHERWISE LITTLE MIXING, THE BASIN MAY EVEN BE HARD PRESSED TO SEE
THE FOG/STRATUS DISAPPEAR FOR A SEVERAL DAY STRETCH. /JBONK

&&

.AVIATION...12Z TAFS...ALL TAF SITES CAN EXPECT TO SEE VERY BREEZY
CONDITIONS OVER THE NEXT 24 HOURS AS A TIGHT PRESSURE GRADIENT WILL
PROVIDE WIND IN EXCESS OF 25 KTS AND GUSTS AROUND 45 KTS AT SOME
LOCATIONS. MAIN TERMINAL OF CONCERN IS KPSC WHERE GUSTS COULD START
EXCEEDING 45 KTS AS EARLY AS 16Z. WILL CONTINUE TO KEEP AN EYE ON
WINDS FOR POSSIBLE AIRPORT WEATHER WARNINGS TO BE ISSUED. CIGS ARE
EXPECTED TO STAY ABOVE 3500 FEET FOR ALL TAF SITES...KEEPING
CONDITIONS IN THE VFR CATEGORY. HOWEVER LOCALIZED BRIEF PERIODS OF
MVFR CIGS ARE POSSIBLE FOR ALL TAF SITES WITH VCSH AND -RA SHOWERS
POSSIBLE. WEBER

A STRONG WESTERLY FLOW WILL BRING STRONG WINDS TO A LARGE PORTION OF
THE AREA THROUGH THIS EVENING. TIGHT PRESSURE GRADIENTS WILL ALLOW
SOME THE STRONG WIND ALOFT TO MIX TO THE SURFACE FROM MID MORNING
THROUGH THE EARLY EVENING. WINDS OF 30 TO 40 MPH WITH HIGHER GUSTS
WILL BE POSSIBLE ACROSS THE ABOVE LISTED AREAS...AS A RESULT WIND
ADVISORIES ARE IN EFFECT. FOR FURTHER INFORMATION PLEASE SEE THE
PRODUCT PDXNPWPDT.

THE STRONG WEST FLOW WILL ALSO KEEP WET WEATHER CONDITIONS OVER THE
PACIFIC NORTHWEST THROUGH TONIGHT. BEST CHANCES OF PRECIPITATION
WILL BE ALONG AND JUST EAST OF THE CASCADE CREST...AND ALONG WEST
FACING SLOPES OF THE INTERIOR NORTHWEST MOUNTAINS. THE HEAVY RAIN OF
THE PAST DAY OR TWO WILL RESULT IN SUBSTANTIAL RISES ON RIVERS AND
STREAMS...WITH THE GREATEST AREA OF CONCERN BEING ALONG THE EAST
SLOPES OF THE SOUTH AND CENTRAL WASHINGTON CASCADES AND OVER THE
EASTERN MOUNTAINS OF OREGON AND WASHINGTON. HOWEVER...AT THIS TIME
FLOODING IS NOT EXPECTED. PLEASE SEE THE PRODUCT PDXESFPDT FOR MORE
DETAILS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

AN UPPER LEVEL HIGH PRESSURE IS EXPECTED TO REBUILD OVER THE EASTERN
PACIFIC THURSDAY. THIS WILL PLACE THE REGION UNDER A SOMEWHAT DRIER
NORTHWEST FLOW. THE UPPER LEVEL RIDGE WILL SHIFT EAST TOWARDS THE
REGION BEGINNING ON FRIDAY. THIS HIGH WILL BRING DRY WEATHER WITH
LIGHT WINDS THROUGH THE WEEKEND INTO EARLY NEXT WEEK. FOGGY
CONDITIONS MAY BECOME A PROBLEM OVER THE COLUMBIA BASIN THIS
WEEKEND.

SPOTTER ACTIVATION MAY BE REQUIRED.

WEATHER SPOTTERS ARE ENCOURAGED TO REPORT SIGNIFICANT WEATHER
CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES.
