AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
959 AM PST THU DEC 31 2015

.SYNOPSIS...AN UPPER LEVEL RIDGE WILL MAINTAIN DRY AND COLD WEATHER
INTO THE WEEKEND. EAST WINDS WILL PREVAIL...AND BE GUSTY THROUGH THE
COLUMBIA GORGE AND THE PORTLAND METRO AREA. LOCATIONS PROTECTED FROM
THE WINDS WILL LIKELY SEE FROST...OR FREEZING FOG IN THE MORNINGS. A
WARM FRONT MAY PRODUCE LIGHT PRECIPITATION ACROSS THE REGION SUNDAY
OR MONDAY.

&&

.UPDATE...EASTERLY FLOW CONTINUES THROUGH THE GORGE THIS MORNING AS
HIGH PRESSURE STRENGTHENS ON THE EAST SIDE OF THE CASCADES. THE
KTTD-KDLS GRADIENT IS CURRENTLY -6.6 MB AND IS FORECAST TO STRENGTHEN
SOME TODAY BUT PEAK LATE TONIGHT AND EARLY FRIDAY MORNING. MODELS
SHOW THE GRADIENT PEAKING AROUND -8.0 MB WHICH SHOULD TRANSLATE TO
WIND GUSTS AROUND 40 MPH FOR THE NORTH VALLEY...OR JUST BELOW
ADVISORY CRITERIA. HOWEVER...MODELS TEND TO BE CONSERVATIVE IN THE
ACTUAL GRADIENT PEAK SO AM STILL UNSURE ON THE NEED FOR AN ADVISORY.
WILL NOT ISSUE ONE FOR NOW BUT WILL REANALYZE THIS AFTERNOON BASED
ON LATEST OBSERVATION TRENDS AND MODEL RUNS.

BASED ON OBSERVATIONS...WINDS ARE MAKING IT WELL INTO CLARK COUNTY AS
WELL AS THE CENTRAL VALLEY...SO HAVE CANCELLED THE AIR STAGNATION
ADVISORY FOR THOSE AREAS. STILL HAVE SOME DOUBTS ABOUT STAGNANT AIR IN
THE LOWER COLUMBIA/I-5 CORRIDOR AND SOUTH VALLEY...BUT THOSE WOULD BE
THE FAVORED AREAS IF IT OCCURS. WILL BE KEEPING AN EYE ON AIR QUALITY
AND POTENTIAL STAGNATION FOR THE NEXT COUPLE OF DAYS.

OTHERWISE NOT MUCH CHANGE TO THE FORECAST ITSELF. REMOVED FOG FROM
THE SOUTH VALLEY THIS MORNING AS IT APPEARS TOO DRY FOR ANYTHING TO
FORM. OVERALL STILL IN FOR A DRY...COLD BUT SUNNY...BREEZY TO WINDY
DAY OUTSIDE OF HOOD RIVER AND THE CASCADE CREST WHICH WILL SEE QUITE
A FEW CLOUDS. BOWEN

.SHORT TERM (PREVIOUS DISCUSSION)...WATER VAPOR IMAGERY SHOWS A
STRONG UPPER LEVEL RIDGE OVER WESTERN CANADA AND WASHINGTON EARLY
THIS MORNING. A SHORTWAVE UPPER TROUGH THAT IS CURRENTLY OVER IDAHO
AND EASTERN OREGON WILL FORM A CUT OFF LOW OVER NORTHERN CALIFORNIA
THIS EVENING...AND FORM A REX BLOCK OVER THE WESTERN STATES. THIS
WILL RESULT IN A STAGNANT WEATHER PATTERN WHERE DRY EAST WINDS...AND
COLD TEMPERATURES WILL PERSIST ACROSS THE PACIFIC NORTHWEST INTO THE
WEEKEND. MINIMUM TEMPERATURES WEST OF THE HIGH CASCADES WILL
GENERALLY BE BELOW 27 DEGREES...EXCEPT THE COAST MAY BE CLOSE TO 30
DEGREES. HIGH TEMPERATURES WILL BE IN THE UPPER 30S TO LOW 40S.

THE UPPER RIDGE HAS RESULTED IN VERY DRY AIR OVER THE REGION THIS
MORNING...WITH DEW POINT TEMPERATURES GENERALLY IN THE LOW TO MID
20S. THIS DRY AIR HAS HELPED SUPPRESS FOG FROM FORMING SO FAR THIS
MORNING. THE BEST CHANCE FOR FOG THIS MORNING IS IN AREAS WHERE THE
DEW POINT TO TEMPERATURE DIFFERENCE IS LOW. CURRENTLY THESE AREAS ARE
BETWEEN CORVALLIS AND EUGENE...AND ALONG THE COLUMBIA RIVER NEAR NEAR
SCAPPOOSE. CLEAR SKIES WILL ALLOW TEMPERATURES TO LOWER THE NEXT FEW
HOURS...ALLOWING OTHER AREAS TO COOL CLOSER TO THE DEW POINT
TEMPERATURES..AND ALSO BE CANDIDATES FOR FREEZING FOG.

DUE TO THE DRY AIR...THINK THERE IS A BETTER CHANCE FOR FROST TO
DEVELOP IN THE AREAS SHELTERED BY THE WINDS THAN FOG. AREAS WHERE THE
EAST WINDS ARE MIXING THE LOWER ATMOSPHERE...LIKE THE COLUMBIA RIVER
GORGE...THE PORTLAND METRO AREA...AND THE OREGON COAST ARE THE LEAST
LIKELY ARES TO SEE FOG OR FROST THIS MORNING. STRATUS IN THE THE
UPPER HOOD RIVER VALLEY OBSERVED IN SATELLITE IMAGERY SHOULD PREVENT
FOG AND FROST FROM DEVELOPING THERE.

THE EASTERLY SURFACE PRESSURE GRADIENT WILL TIGHTEN THIS AFTERNOON
AND EVENING...INCREASING EAST WINDS THROUGH THE COLUMBIA RIVER GORGE
AND PORTLAND METRO AREA. FORECAST SOUNDINGS SUGGEST THAT THE EAST
WINDS WILL BE RATHER DEEP IN THE ATMOSPHERE AND MAY BE MORE
WIDESPREAD THROUGH THE FOOTHILLS...WILLAMETTE VALLEY...AND COAST
RANGE THAN THE MORE TYPICAL EASTERLY GAP WINDS. THE CURRENT MODELS
FORECAST A DALLES TO PORTLAND GRADIENT AROUND 8 MB LATE THIS
AFTERNOON THROUGH SATURDAY MORNING WHICH COULD PRODUCE EAST GUSTS OF
35 TO 40 MPH FOR THE PORTLAND METRO AREA.

THE MODELS SOMETIMES UNDER-ESTIMATE THE STRENGTH OF THE EASTERLY
GRADIENT BY 1 TO 2 MB. IF THIS IS ONE OF THOSE TIMES...THEN GUSTS OF
45 TO 50 MPH ARE POSSIBLE IN THE PORTLAND METRO AREA...WHICH WOULD
RESULT IN MORE SIGNIFICANT IMPACTS. THE FORECAST CONFIDENCE IS NOT
HIGH ENOUGH TO ISSUE A WIND ADVISORY FOR THE METRO AREA AT THIS
TIME...BUT IF THE GRADIENT TIGHTENS FASTER AND STRONGER THAN THE
MODELS SUGGEST...ONE MIGHT BE NEEDED.  EAST GUSTS IN THE GORGE SHOULD
REMAIN BELOW THE HIGH WIND WARNING THRESHOLD OF 75 MPH GUSTS...EXCEPT
AT ISOLATED EXPOSED PLACES LIKE CROWN POINT WHERE GUSTS WILL BE
HIGHER. SHOULD THIS BECOME A MORE SYNOPTIC-DRIVEN OFFSHORE
EVENT...THERE WOULD BE ENOUGH MIXING IN MANY VALLEYS TO REDUCE THE
AIR STAGNATION POTENTIAL. TJ

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...SATURDAY NIGHT
THROUGH WEDNESDAY...STRONG UPPER-LEVEL RIDGING KEEPS US DRY THROUGH
THE WEEKEND...WITH EASTERLY FLOW THROUGH THE GORGE KEEPING FOG OUT OF
THE PORTLAND/VANCOUVER METRO. THE REST OF THE WILLAMETTE VALLEY WILL
LIKELY CONTINUE TO SEE FREEZING FOG SATURDAY NIGHT AND SUNDAY NIGHT.
CLOUDS WILL START INCREASING EARLY MONDAY WITH THE APPROACH OF A LOW
PRESSURE SYSTEM OUT OF THE SOUTHWEST. WITH THIS SYSTEM...MOISTURE
WILL STRUGGLE TO MAKE IT PAST THE COAST RANGE ON MONDAY. ON
TUESDAY...THE COLD FRONT WILL MOVE THROUGH PUSHING RAIN INLAND ACROSS
OUR AREA. MONDAY AND TUESDAY WILL HAVE TO BE MONITORED
CLOSELY...BECAUSE THE MODELS ARE LIKELY TRYING TO SCOUR OUT THE COLD
AIR IN THE WILLAMETTE VALLEY TOO QUICKLY. WE COULD DEFINITELY SEE A
PERIOD OF WINTRY PRECIP ON THE FRONT SIDE OF THIS SYSTEM IN THE
WILLAMETTE VALLEY...AS COLD AIR REMAINS TRAPPED AT LOWER LEVELS. A
CHANCE OF RAIN CONTINUES INTO WEDNESDAY...THOUGH BY THEN THE COLD AIR
SHOULD HAVE ERODED AWAY TURNING PRECIP TO ALL RAIN BELOW 2000-3000
FT. -MCCOY

&&

.AVIATION...STRONG OFFSHORE FLOW PATTERN WILL BE IN PLACE THROUGH
FRIDAY. WILL HAVE BREEZY EAST WINDS IN/AROUND THE GAPS IN THE
CASCADES AND OVER THE RIDGES...MAINLY TO WEST OF THE CASCADE CREST
BETWEEN MT RAINIER AND MT JEFFERSON. PERSISTENT STRATUS IN THE
COLUMBIA BASIN WILL BANK CLOUDS ALONG THE CASCADE CREST AND
EASTERN COLUMBIA RIVER GORGE FOR THE NEXT SEVERAL DAYS.
OTHERWISE...SKIES WILL BE CLEAR WITH VFR CONDITIONS ASIDE FROM
SOME PATCHES OF NIGHT/MORNING FOG...MAINLY TO N OF KSPB INTO THE
COWLITZ VALLEY...AS WELL AS NEAR KEUG. FOG/STRATUS WILL BE
SHALLOW AND MOST PREVALENT ALONG/EAST OF INTERSTATE 5...WITH
CLOUD/FOG TOPS AT OR BELOW 1000 FT MSL THE FOG SHOULD MOSTLY
DISSIPATE BY AFTERNOON.

KPDX AND APPROACHES...VFR WITH GUSTY EAST WINDS THROUGH FRI.
EXPECT GUSTS TO 35 KT NEAR KPDX AT TIMES...WITH GUSTS AS HIGH AS
45 KT NEAR THE WEST END OF THE COLUMBIA GORGE.	WEAGLE

&&

.MARINE...NOT MUCH CHANGE OVER NEXT FEW DAYS. STRONG HIGH PRES
WILL REMAIN ANCHORED OVER THE INLAND PAC NW...WITH BRISK OFFSHORE
FLOW ACROSS THE COASTAL WATERS. WINDS WILL BE STRONGEST NEAR GAPS
IN THE COASTAL TERRAIN...WHERE GUSTS TO 30 KT ARE LIKELY AND A
FEW GALE FORCE GUSTS TO 35 KT POSSIBLE. MODELS SHOWING A BREAKING
DOWN OF THE HIGH PRES EARLY NEXT WEEK WITH PACIFIC LOWS
APPROACHING THE REGION...BUT MODEL SOLUTIONS VARY WIDELY WITH THE
DETAILS AT THIS TIME. WITH AN UPPER LEVEL RIDGE BLOCKING THE
STORM TRACK TOWARD ALASKA...WILL BE DIFFICULT TO GENERATE MUCH
SWELL TO REACH THE PAC NW COAST THE NEXT FEW DAYS. THUS SEAS WILL
GENERALLY HOLD AT 5 TO 7 FT THROUGH THE WEEKEND. AS LOWS START TO
UNDERCUT THE UPPER RIDGE EARLY NEXT WEEK...SEAS WILL LIKELY
INCREASE ABOVE 10 FT AS THE PATTERN BECOMES SLIGHTLY MORE ACTIVE.
