AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
925 PM PST MON DEC 7 2015
.SYNOPSIS...ANOTHER FRONT WILL BRING RAIN AND BREEZY CONDITIONS TO
THE REGION AGAIN TUE INTO WED...WITH ANOTHER ROUND OF RAIN AND WIND
WED NIGHT AND THU. THEN COOLER AND SHOWERY FRI INTO THIS WEEKEND WITH
SNOW LEVELS AROUND THE CASCADES PASSES.
&&
.SHORT TERM...TONIGHT THROUGH WEDNESDAY...
RAIN ENDED THIS AFTERNOON...WITH JUST A FEW LIGHT SHOWERS AROUND THE
REGION THIS EVENING. STILL HAVE AREAS WHERE WATER IS SLOWLY DRAINING.
MOTORISTS SHOULD BE PREPARED FOR STANDING WATER IN LOW LYING AREAS
THIS EVENING. BUT OVERALL...WATER WILL GRADUALLY RECEDE.
PLENTY OF RIVERS THAT ARE EXPERIENCE SOME DEGREE OF FLOODING THIS
EVENING...ESPECIALLY THOSE COASTAL RIVERS. BUT THESE TOO ARE SHOWING
SIGNS OF CRESTING. SO...BOTTOM LINE..IT APPEARS WORST MAY BE OVER.
UNFORTUNATELY...ANOTHER SYSTEM IS FAST APPROACHING FROM THE WEST.
ISENTROPIC LIFT RETURNS LATER THIS EVENING...WITH LIGHT RAIN
RETURNING OVERNIGHT AND INTO EARLY TUE AM...BUT RAINFALL WILL BE
NOTHING LIKE WHAT OCCURRED SUN NIGHT INTO MON AM. MODELS STILL RATHER
INSISTENT ON PUSHING THE WARM FRONT WELL NORTH OF THE REGION TUE AM.
MAY VERY WELL SEE A BREAK IN THE RAIN WITH JUST CLOUDS OVER THE AREA
TUE AM. HOWEVER...EXPECT BREEZY SOUTHERLY WINDS TO DEVELOP OVER AREA
BEHIND THE WARM FRONT. NAM AND MM5 MODELS STILL INDICATE SUBTLE
TIGHTENING OF PRES GRADIENTS TOWARDS DAYBREAK ALONG THE COAST. SHOULD
BE ENOUGH TO SUPPORT GUSTS OF 60 TO 70 MPH WINDS ON THE COAST AND
EXPOSED RIDGES IN THE COASTAL MOUNTAINS...WITH GUSTS 50 TO 65 MPH FOR
THE COASTAL COMMUNITIES. LIKELY SEE THESE WINDS PERSIST THROUGH THE
MORNING AND WELL INTO THE AFTERNOON BEFORE EASING IN THE EVENING.
WILL UPGRADE THE HIGH WIND WATCH TO A HIGH WIND WARNING FOR COAST AND
COAST MTNS/WILLAPA HILLS FOR LATE TONIGHT AND TUE. WILL MAINTAIN THE
HIGH WIND WATCH FOR THE HIGH CASCADES.
THE COLD FRONT WILL PUSH INTO THE REGION LATE TUE AFTERNOON AND
EVENING...BRINGING MODERATE TO HEAVY RAIN TO REGION LATE TUE
AFTERNOON AND TUE NIGHT. IT APPEARS THE AXIS OF STRONGEST MOISTURE
FLUX AND HEAVIEST RAIN WILL RESIDE OVER THE WILLAPA HILLS OR OLYMPIC
MUCH OF THE DAY TUE...THEN SPREAD DOWN THROUGH SW WASHINGTON AND NW
OREGON TUE NIGHT AND EARLY WED. FORCING LOOKS VERY IMPRESSIVE FOR
HEAVY RAIN ALONG THIS FRONT...BUT IT MAY BE FASTER MOVING THAN THE
SYSTEM WHICH DUMPED HEAVY RAIN ACROSS THE FORECAST AREA TODAY.
THEREFORE EXPECT RAINFALL RATES SIMILAR OR POSSIBLY EVEN SLIGHTLY
HEAVIER THAN TODAY...BUT FOR A SHORTER DURATION...AT LEAST FOR THE
LOWLANDS. HOWEVER WILL NEED TO MONITOR THE POTENTIAL FOR A SECONDARY
WAVE DEVELOPING ALONG THE FRONT AND HOLDING IT UP...WHICH IS WHAT THE
12Z AND 18Z NAM/GFS HAVE BEEN SHOWING. THIS WOULD RESULT IN A 6-12
HOUR PERIOD OF 0.25-0.50 INCH RAIN RATES IN THE SAME AREA THAT
RECEIVED SUCH RATES EARLIER TODAY. FOR NOW WE ARE GOING WITH SLIGHTLY
MORE CONSERVATIVE TOTALS...BUT STILL IMPRESSIVE. LOOKING AT ANOTHER
1-3 INCHES FOR THE LOWLANDS AND 3-7 INCHES IN THE HIGHER
TERRAIN...WHICH WILL ONLY EXACERBATE CURRENT FLOODING ISSUES. EVEN
WITH FLOOD WARNINGS CURRENTLY IN PLACE FOR MORE THAN 10 RIVERS...
THERE MAY BE ADDITIONAL WARNINGS NEEDED.
.LONG TERM...WEDNESDAY THROUGH MONDAY...A STRONG FRONT TO MOVE
THROUGH THE REGION OVERNIGHT TUE INTO EARLY WED. THE FCST MODELS IN
GOOD GENERAL AGREEMENT WITH THE TIMING OF THE FRONT...BRINGING IT
INTO THE CASCADES BY DAYBREAK WED...THEN EAST OF THE CASCADES DURING
WED MORNING. EXPECT A BREAK FROM THE HEAVY RAIN AND WIND FOR THE
REST OF THE DAY WED WITH ONLY SOME RELATIVELY LIGHT POST FRONTAL
SHOWERS REMAINING. SNOW LEVELS WILL REMAIN WELL ABOVE 6000 FT DURING
MOST OF THE FRONTAL PRECIPITATION TUE NIGHT...BUT WILL THEN DROP
CONSIDERABLY ON THE BACKSIDE OF THE FRONT. THIS WILL LIKELY ALLOW
THE CASCADE PASSES TO PICK UP A COUPLE INCHES OF SNOW ON WED.
YET ANOTHER LOW PRES SYSTEM IS EXPECTED TO FORM ALONG THE STALLED
BAROCLINIC ZONE AND AFFECT THE PAC NW WED NIGHT INTO THU. THIS SYSTEM
APPEARS TO HAVE THE POTENTIAL TO BE QUITE STRONG...WITH THE FCST
MODELS INDICATING A SURFACE LOW WITH A CENTRAL PRES APPROACHING 960
MB. HOWEVER...FCST CONFIDENCE IN THE DETAILS ON TIMING AND
POSITIONING OF THIS SYSTEM ARE NOT ALL THAT HIGH. THE 12Z AND 18Z
RUNS OF THE NAM BRING THE LOW FROM SOUTHWEST TO NORTHEAST AND
ONSHORE ALONG THE WA COAST...WHICH WOULD LEAD TO STRONG WINDS FOR
THE COAST AND COAST RANGE. THE 12Z GFS AND ECMWF SOLUTIONS ARE
CONSIDERABLY DIFFERENT...KEEPING THE LOW FURTHER NORTH AND BRINGING
A MORE MORE GLANCING BLOW FROM AN ASSOCIATED OCCLUDED FRONTAL
BOUNDARY WED NIGHT INTO THU. THESE MODELS THEN BRING THE LOW SOUTH
TOWARD THE PAC NW THU NIGHT INTO FRI. WILL KEEP THE WIND FCST MORE
IN LINE WITH THE THE ECMWF/GFS SOLUTION FOR NOW. EITHER WAY...EXPECT
ANOTHER ROUND OF DECENT ROUND OF PRECIPITATION WED NIGHT INTO THU
MORNING...WITH PLENTY OF SHOWERS REMAINING THROUGH THE DAY THU. SNOW
LEVELS WILL BE LOWER WITH THIS SYSTEM...AND EXPECT WE WILL HAVE THE
POTENTIAL TO PICK UP DECENT SNOWFALL DOWN TO THE CASCADE PASSES.
A FAIRLY COLD AND BROAD UPPER LEVEL TROUGH IS MODELED TO DIG INTO
THE PAC NW TO END THE WEEK...WITH QUITE A BIT OF SHOWER ACTIVITY
LIKELY AROUND ON FRI AND PRECIPITATION FALLING AS SNOW IN THE
CASCADES. FCST CONFIDENCE DECREASES GOING INTO THE WEEKEND AND EARLY
NEXT WEEK. HOWEVER...IT DOES APPEAR THAT A MORE PROGRESSIVE PATTERN
PREVAILS. FOR NOW...WILL KEEP TEMPS AND POPS NEAR CLIMO AND WAIT
UNTIL MODEL AGREEMENT INCREASES BEFORE TRYING TO ADD MUCH DETAIL TO
THE FCST. PYLE
&&
.AVIATION...A WEAK WARM FRONT WILL SPREAD LIGHT RAIN BACK INTO
THE REGION WITH SCATTERED SHOWERS INTERMIXED. THIS SHOULD BRING A
MIX OF MVFR AND VFR CONDITIONS INLAND AND A MIX OF IFR AND MVFR
CONDITIONS ALONG THE COAST. INCREASING SOUTH WINDS TOWARDS 12Z
TUESDAY SHOULD PREVENT IFR CONDITIONS FROM BECOMING TOO
ESTABLISHED AT ANY OF THE INTERIOR TAF SITES...WITH PERHAPS MOST
TRENDING VFR. HOWEVER...ANY IMPROVEMENTS WILL BE SHORT LIVED AS
ANOTHER FRONTAL RAIN BAND CAPABLE OF BRINGING MODERATE RAIN WILL
CAUSE CONDITIONS ACROSS THE INTERIOR TO DETERIORATE SOLIDLY INTO
MVFR. SOUTH WIND GUSTS ALONG THE COAST WILL ONCE AGAIN CLIMB INTO
THE 40 TO 50 KT RANGE...PARTICULARLY AT KONP...AFTER 12 TO 18Z
TUESDAY.
KPDX AND APPROACHES...EXPECT A MIX OF MVFR AND VFR CONDITIONS
OVERNIGHT AS A WARM FRONT BRINGS LIGHT RAIN. INCREASING SOUTH
WINDS TOWARDS 12Z TUESDAY SHOULD KEEP IFR CONDITIONS FROM
DEVELOPING. A FRONTAL RAIN BAND WILL SHIFT SOUTHWARD TOWARDS THE
TERMINAL SOME TIME TOWARDS 00Z TO 06Z WEDNESDAY WITH CONDITIONS
LIKELY DETERIORATING MORE SOLIDLY INTO MVFR CONDITIONS. /NEUMAN
&&
.MARINE...WINDS HAVE EASED ACROSS THE WATERS...BUT ARE EXPECTED TO
INCREASE ONCE AGAIN LATER TONIGHT AS A WARM FRONT LIFTS
NORTHEASTWARD ACROSS THE WATERS. AS A RESULT...SEAS WILL CONTINUE
IN THE LOW TO MID TEENS THROUGH TUESDAY MORNING...BUT WILL LIKELY
BUILD BACK INTO THE MID TO UPPER TEENS TUESDAY AFTERNOON AND
POSSIBLY ECLIPSE 20 FT ONCE AGAIN. EXPECT SOLID GALE FORCE WIND
GUSTS OF 40 TO 45 KT ACROSS THE WATERS ON TUESDAY AS A COLD FRONT
SHIFTS SOUTHEASTWARD ACROSS THE WATERS. THIS SHOULD RESULT IN
WINDS EASING CONSIDERABLY ACROSS THE NORTHERN WATERS TUESDAY
AFTERNOON...BUT THEY WILL LIKELY LINGER THROUGH TUESDAY NIGHT
ACROSS THE CENTRAL OREGON WATERS. IT SHOULD BE NOTED THAT THERE
COULD STILL BE A FEW STORM FORCE WIND GUSTS OF 50 KT ACROSS THE
WATERS...PARTICULARLY WITHIN 20 NM OF THE CENTRAL OREGON COAST
TUESDAY NIGHT. BECAUSE WINDS WILL BE MOST PERSISTENT ACROSS THE
CENTRAL OREGON WATERS...THIS REGION STANDS THE BEST CHANCE OF
SEEING SEAS CLIMB INTO THE 20 TO 23 FT RANGE TUESDAY NIGHT.
ANOTHER WARM FRONTAL WAVE APPEARS THAT IT MAY CAUSE GALE FORCE WINDS
TO SPREAD BACK NORTHWARD LATE TUESDAY NIGHT AND EARLY WEDNESDAY
MORNING INTO AT LEAST A PORTION OF THE NORTHERN WATERS...BUT
CONFIDENCE IS NOT TERRIBLY HIGH IN THIS SCENARIO EITHER. WILL
CONTINUE TO MONITOR. SEAS WILL LIKELY CONTINUE TO LINGER IN THE 15
TO 20 FT RANGE THROUGH WEDNESDAY NIGHT.
THE CONCERN WILL THEN SHIFT TO A VERY DEEP SURFACE LOW PRESSURE
SYSTEM...SOMEWHERE ON THE ORDER OF 960 TO 970MB...THAT IS
EXPECTED TO DEVELOP IN THE NORTHEAST PACIFIC OCEAN. THE EC AND GFS
REMAIN IN RELATIVELY GOOD AGREEMENT THAT THIS SYSTEM WILL SPIN UP
AND MOVE NORTHEASTWARD TOWARDS THE WATERS BETWEEN VANCOUVER ISLAND
AND HAIDA GWAII. A NEGATIVELY TILTED OCCLUSION WILL LIKELY BRING A
BOUT OF HIGH END GALE FORCE TO LOW END STORM FORCE WINDS TO THE
WATERS ON WEDNESDAY NIGHT OR THURSDAY. IN ADDITION...WAVE MODELS
HAVE FLUCTUATED BETWEEN A 25 TO 40 FT WESTERLY SWELL AT
APPROXIMATELY 15 TO 17 SECONDS MOVING INTO THE WATERS SOME TIME
THURSDAY/FRIDAY. FOR NOW...WENT WITH A MIDDLE OF THE ROAD
APPROACH TOWARD SEA HEIGHTS IN COLLABORATION WITH SURROUNDING
OFFICES. EITHER WAY...BESIDES BRINGING EXTREMELY DANGEROUS SEA
CONDITIONS TO THE WATERS DURING THIS PERIOD...WAVES THIS SIZE FROM
A WESTERLY DIRECTION WILL ALMOST CERTAINLY BRING HIGH SURF
CONDITIONS AND COASTAL FLOODING. AS A RESULT...THE CURRENT
COASTAL FLOOD WATCH LOOKS TO BE IN GOOD SHAPE.
IN ADDITION...THE HIGH RIVER FLOWS ACROSS THE REGION COUPLED WITH
TIDAL ANOMALIES OF 1 TO 2 FT AND HIGHER THAN NORMAL TIDES...WILL
LIKELY RESULT IN SOME MINOR TIDAL OVERFLOW FLOODING ALONG OUR
COAST. AT THIS POINT...THE TIDES OF CONCERN WILL BE AROUND 10 TO
11 AM TUESDAY AND WEDNESDAY MORNING AND THE CURRENT TIDAL OVERFLOW
ADVISORY LOOKS ON TRACK. /NEUMAN

CROCKEYThe national radar mosaic for the moment the first event began.
2 flood, 2 heavy rain. Local standard time, as filed.
Heavy rain resulted in flooding of the Lukiamute River near Suver.
Heavy rain resulted in urban flooding across the Portland metro area. All Amtrack and freight trains were shut down between Portland and Vancouver due to flooding. A mobile home park in Gresham flooded. There were a couple of land slides on Highway 30 where debris covered the highway. One of these slides was near German Town Road. The other slide was near the St John's Bridge, hit a car (with no injuries) as it happened, and covered all lanes of Highway 30.
Flooding from the Nehalem River and Rock Creek in Vernonia resulted in evacuation of homes and the implementation of the Vernonia Emergency Command Center. Heavy rain resulted in a land slide that closed OR47 at mile marker 8.
The Oregon State route 22 was closed due to erosion (sinkhole) from heavy rain. Oregon state route 153 was closed due to high water on the roads between mile markers 1 and 6.
