AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PORTLAND OR
1022 AM PST THU MAR 6 2014
UPDATED AVIATION AND MARINE DISCUSSIONS
.SYNOPSIS...A LOW PRESSURE CENTER OFF THE WA COAST EARLY THIS
MORNING WILL MOVE INLAND OVER VANCOUVER ISLAND TODAY. IT WILL DRAG
AN OCCLUDED FRONT ACROSS THE AREA ALSO. PEAK WINDS HAVE REACHED THE
CENTRAL COAST WILL SHOULD BE OVER THE CASCADES BY MID-DAY. WESTERLY
FLOW BEHIND THE FRONT WILL KEEP SHOWERS GOING TONIGHT ESP OVER THE
MOUNTAINS. A RIDGE OF HIGH PRES WILL BRING DRIER MILD WEATHER FRI
INTO SAT. THE NEXT PACIFIC FRONTAL SYSTEM IS EXPECTED TO MOVE
THROUGH SAT NIGHT AND SUN.
&&
.UPDATE...MAIN FEATURE OF INTEREST IS A SECONDARY SURFACE LOW THAT
HAS SPUN UP OFF THE MOUTH OF THE COLUMBIA OVERNIGHT. IT IS CURRENTLY
COMING ONSHORE OVER LONG BEACH. MODELS...INCLUDING THE
HRRR/RAP...HAVE NOT PICKED UP ON IT ALL SO AM RELYING ON EXPERIENCE
FOR THE IMMEDIATE EVOLUTION. FORTUNATELY...RADAR AND SATELLITE DATA
MAKE IT APPEAR AS THOUGH THE LOW HAS ALREADY REACHED IT'S LOWEST
PRESSURE AND IS ALREADY FILLING AND THUS WEAKENING. MAIN IMPACT
LOOKS LIKE IT WILL BE SLIGHTLY HIGHER SOUTHERLY WIND GUST POTENTIAL
ACROSS THE NORTHEASTERN TIER OF THE CWA THIS MORNING AS SURFACE
PRESSURE GRADIENTS WILL BE A LITTLE TIGHTER THAN MODELS WOULD
OTHERWISE INDICATE. HAVE ALREADY SEEN GUSTS INTO THE 40S IN PORTIONS
OF THE VALLEY. VERY LOW LEVEL RADAR VELOCITY DATA IS NOT OVERLY
CONCERNING BUT DID SHOW 35 KT INBOUND AND IMMEDIATELY ADJACENT TO
THE RADAR AT ABOUT 830 AM SO EXPECT THAT LEVEL OF GUSTS TO REACH THE
FOOTHILLS AT TIMES WITH A BETTER CHANCE ALONG THE CASCADES.
ADDITIONALLY...BUOY 89 IS SHOWING A 3-HOURLY PRESSURE RISE OF 8.5 MB
WITH IS RATHER SIGNIFICANT. THIS TYPICALLY INDICATES POTENTIAL FOR
STRONG COLD ADVECTION AND ASSOCIATED SINKING MOTION BEHIND A FRONT,
BUT IN THIS CASE, COULD BE MORE OF AN ARTIFACT OF THE NEARLY DIRECT
HIT BY THE LOW CENTER. WILL STILL CONTINUE THE WARNINGS AND ADVISORY
FOR THE VALLEY AND NORTH COAST AREAS AS STILL FEEL LIKE THERE WILL
BE PLENTY OF WESTERLY WIND POTENTIAL AS THE PRIMARY WRAP AROUND
OCCLUSION BAND MOVES ONSHORE TODAY. LOOKS LIKE THE CENTRAL
COAST/COAST RANGE IS GENERALLY DONE WITH WARNING LEVEL WIND GUSTS SO
WILL LET THE WARNINGS EXPIRE AS PLANNED.
A SIDE BENEFIT/DETRIMENT...DEPENDING ON YOUR WEATHER
PREFERENCES...OF THE SECONDARY LOW WAS TO PUSH THE BEST UPPER LEVEL
DYNAMICS FURTHER SOUTH. HAVE SEEN SEVERAL LIGHTNING STRIKES THIS
MORNING JUST SOUTH OF THE LANE/DOUGLAS COUNTY BORDER. THUS HAVE
DECIDED TO LIMIT A SLIGHT CHANCE MENTION FOR THE SOUTHERN 1/4/ OF
THE AREA. DO NOT HAVE THE CONFIDENCE ONE WILL EVEN OCCUR THUS USING
PROBABLY WORDING INSTEAD OF THE HIGHER CONFIDENCE COVERAGE WORDING
IN THE ZONES.
FINALLY...THE SECOND LOW ALSO APPEARS TO BE HOLDING TEMPERATURES
ALONG THE CENTRAL CASCADES HIGHER FOR THE TIME BEING KEEPING SNOW
LEVELS ABOVE WILLAMETTE AND SANTIAM PASS. STILL SEEMS LIKE SNOW
LEVELS WILL LOWER THIS AFTERNOON BUT STILL DONT SEEM TO BE CRASHING
DOWN. WILL LEAVE THE SNOW ADVISORIES IN PLACE FOR NOW BUT FEEL A
NEED TO REEVALUATE FOR THE AFTERNOON PACKAGE. UPDATED GRIDS FOR
TODAY SHOULD BE AVAILABLE SHORTLY WITH ZONES FOLLOWING CLOSELY
AFTER. /JBONK
&&
.PREVIOUS DISCUSSION... /ISSUED 330 AM PST THU MAR 6 2014/
SHORT TERM...INTENSE SFC LOW OFF THE WA COAST EARLY THIS MORNING WAS
EXPECTED TO CONTINUE NE THIS MORNING MOVING INLAND OVER VANCOUVER
ISLAND. RADAR AND SURFACE OBS SHOWERS SHOWERS WERE WIDESPREAD OVER
ALL BUT THE SE PART OF THE FORECAST AREA. THUNDERSTORMS HAVE ALSO
BEEN ACTIVE MAINLY ALONG THE COAST. WILL INCLUDE CHANCE FOR THUNDER
INLAND TODAY AS WELL AS ALONG THE COAST AS THE SHARP UPPER TROUGH
MOVES THROUGH AND INLAND TEMPS AND DEWPOINTS ARE COMPARABLE TO THOSE
AT THE COAST. WINDS ALONG THE COAST HAVE BEEN GUSTING OVER 50 MPH
MUCH OF THE NIGHT...AND WITH THE OCCLUDED FRONT MOVING IN THIS
MORNING EXPECT PEAK GUSTS BACK ABOVE 60 MPH. AS THE OCCLUSION MOVES
INLAND LATER THIS MORNING ALREADY GUSTY WINDS IN THE INLAND VALLEYS
WILL PICK UP ALSO WITH THE STRONGER SOUTHERLY PRES GRADIENTS...SO
WIND ADVISORY THERE ALSO LOOKS ON TRACK. WITH THE APPROACH OF THE
UPPER TROUGH TEMPS AND SNOW LEVELS IN THE HIGHER ELEVATIONS OF THE N
CASCADES HAVE BEGUN TO LOWER...WITH TIMBERLINE LODGE AT 7K FT
SHOWING TEMPS DOWN TO 27 DEG AT 1 AM. SO INITIALLY AS THE HEAVIER
PRECIPITATION MOVES IN THIS MORNING SNOW LEVELS WILL BE FAIRLY
HIGH...BUT OUGHT TO QUICKLY DROP DOWN TO NEAR THE HIGHER CASCADE
PASSES THIS AFTERNOON. STRONG OROGRAPHICS WILL DEVELOP WITH THE
SWITCH TO MORE WESTERLY WINDS BEHIND THE FRONT LATER THIS MORNING.
WILL LEAVE WINTER WEATHER ADVISORIES UP FOR N PART OF THE
CASCADES...FURTHER S SNOWFALL TOTALS MAY BE CLOSE TO ADVISORY
CRITERIA BUT EXPECT SNOW LEVELS TO BE A LITTLE SLOWER TO FALL THIS
MORNING.
TONIGHT INTO FRI MODELS AGREE ON BUILDING A TRANSIENT RIDGE OVER THE
PACIFIC NW...CUTTING OFF THE FAVORABLE OROGRAPHICS AND STABILIZING
THE ATMOSPHERE. THIS WILL BRING SHOWERS TO AN END FRI AS AIR MASS
WARMS. SHOULD SEE TEMPS WARM ABOVE 60 BY SAT WITH H8 TEMPS WARMING
TO 6 TO 7 DEG C AND AN OFFSHORE SURFACE FLOW. WILL BACK OFF ON POPS
FOR SAT AS MODELS HAVE SLOWED THE APPROACH OF THE NEXT
PACIFIC FRONTAL SYSTEM.
LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS. SATURDAY NIGHT
THROUGH WEDNESDAY...12Z MODELS CONTINUE TO SHOW THE NEXT SYSTEM
TAPPING INTO ABUNDANT TROPICAL MOISTURE THIS WEEKEND. THE FRONTAL
SYSTEM WILL SLOWLY SAG SOUTH ACROSS THE FORECAST AREA SATURDAY NIGHT
INTO SUNDAY...WITH ANOTHER SYSTEM PUSHING ONSHORE MIDDAY SUNDAY AND
DUMPING RAIN THROUGH LATE SUNDAY NIGHT. THE ECMWF APPEARS TO BE THE
OUTLIER...SHOWING MUCH OF THE ENERGY FOCUSED SOUTH OF THE CWA WHILE
THE GFS MAINTAINS THE THREAT FOR HEAVY RAIN INTO LATE SUNDAY NIGHT.
POST FRONTAL SHOWERS LINGER INTO MONDAY...BEFORE MODEL SOLUTIONS
DIVERGE TUESDAY ONWARD. ALL IN ALL...BOTH MODELS SHOW AN UPPER LEVEL
RIDGE STRENGTHENING OVER THE REGION BY MID WEEK. /27
&&
.AVIATION...NUMEROUS SHOWERS AND GUSTY SSW WINDS AFFECTING THE
REGION THIS MORNING IN ASSOCIATION WITH A STRONG LOW PRES SYSTEM
PRESENTLY LOCATED NEAR VANCOUVER ISLAND. MIXED BAG OF MVFR AND VFR
ACROSS THE INLAND TERMINALS WHILE SOLID MVFR ALONG THE COAST.
SUSPECT MORE WIDESPREAD MVFR INLAND AS SURFACE BOUNDARY PUSHES
INLAND SPREADING LOCALLY HEAVIER RAIN THROUGH ABOUT 21Z. SOME
SHOWERS REMAIN THROUGH THE AFTERNOON...WITH A MIX OF VFR AND MVFR
CONDITIONS THROUGH THE EVENING. DEPENDING ON THE AMOUNT OF
CLEARING AFTER THE FRONT...THERE IS A CHANCE OF SOME FOG
DEVELOPMENT LATE TONIGHT. STRONG 850 MB WIND FLOW INTO THE
ELEVATED TERRAIN WILL RESULT IN MOUNTAIN OBSCUREMENT THROUGH THIS
EVENING.
KPDX AND APPROACHES...VFR SHOULD GIVE WAY TO MVFR CONDITIONS
THROUGH EARLY AFTERNOON AS THE SURFACE TROF MOVES CLOSER TO THE
TERMINAL...BRINGING SOME LOCALLY HEAVY RAIN AND S-SW SURFACE WIND
GUSTS TO 35 KT. GENERAL IMPROVEMENT TO VFR IN SHOWERS THIS
AFTERNOON AND TONIGHT. CULLEN
&&
.MARINE...A STRONG LOW PRES SYSTEM PUSHING TOWARD VANCOUVER ISLAND
THIS MORNING IS BRINGING STRONG WINDS AND HAZARDOUS SEAS TO THE
COASTAL WATERS THIS MORNING. SOME GALES REMAINING OVER THE WATERS
AT THIS HOUR...SO HAVE INCLUDED ALL OF THE WATERS IN THE GALE
WARNING THROUGH 21Z. AFTER THIS SURFACE TROF PUSHES INLAND EARLY
THIS AFTERNOON...EXPECT WINDS SPEEDS TO DIMINISH THOUGH SOME GUSTS
TO 30KT POSSIBLE INTO THU NIGHT BEFORE CONDITIONS SETTLE DOWN. THE
NEXT FRONT LOOKS TO IMPACT THE WATERS ON SAT EVENING.
COMBINED SEAS THIS MORNING RANGE SIT IN THE 17 TO 20 FT
RANGE...WITH THE PRIMARY COMPONENT FROM LOCALLY GENERATED SHORT
PERIOD WIND WAVES. EXPECT SEAS TO EASE BACK INTO THE LOW TEENS BY
EARLY FRI MORNING. CULLEN
