AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
1031 AM PST MON DEC 7 2015
.SYNOPSIS...A SERIES OF STRONG AND MOIST PACIFIC FRONTAL SYSTEMS WILL
CONTINUE TO LASH SOUTHWEST WASHINGTON AND NORTHWEST OREGON WITH
PERIODS OF HEAVY RAIN...STRONG WINDS...AND HEAVY SURF FOR MUCH OF THE
UPCOMING WEEK. THE LATEST SYSTEM IS BRINGING HEAVY RAIN TO MUCH OF
THE FORECAST AREA THIS MORNING...WITH STRONG WINDS ALONG THE COAST.
GUSTY WINDS WILL SPREAD INLAND BY EARLY AFTERNOON AS LOW PRESSURE
MOVES ONSHORE. A BRIEF BREAK IN THE HEAVIEST RAIN WILL FOLLOW...THEN
MORE HEAVY RAIN AND STRONG WIND ARE EXPECTED WITH THE NEXT FRONT
TUESDAY AND TUESDAY NIGHT. ADDITIONAL STORM SYSTEMS WILL LIKELY BRING
MORE WET AND WINDY WEATHER AS THE WEEK PROGRESSES. HIGH SURF CAN BE
EXPECTED AT TIMES ALONG THE COAST...WITH SOME COASTAL FLOODING
POSSIBLE AS WELL. ALL THIS RAIN WILL ONLY EXACERBATE FLOODING ISSUES
WHICH ARE ALREADY BEGINNING TO TAKE SHAPE ACROSS SOUTHWEST WASHINGTON
AND NORTHWEST OREGON.
&&
.MORNING UPDATE...HEAVY RAIN AND STRONG COASTAL WINDS ARE IN PROGRESS
RIGHT NOW...WITH SIGNIFICANT URBAN AND SMALL STREAM FLOODING BEING
REPORTED AROUND THE PORTLAND AND VANCOUVER METRO AREA. WE HAVE HAD
2.30 INCHES HERE AT THE OFFICE IN NE PORTLAND JUST SINCE
MIDNIGHT...WITH 1.91 INCHES IN THE PAST 6 HOURS. RAIN RATES HAVE
LOCALLY EXCEEDED 0.50 INCH PER HOUR...EVEN FOR THE LOWLANDS. AS A
RESULT WE WILL BE UPGRADING THE URBAN AND SMALL STREAM FLOOD ADVISORY
TO A WARNING SHORTLY FOR OUR NORTHERN ZONES. RAIN RATES ARE MUCH
LIGHTER SOUTH...WITH A FEW HUNDREDTHS OR A COUPLE TENTHS OF AN INCH
PER HOUR...SO THE EXISTING ADVISORY WILL SUFFICE. THE HEAVIEST RAIN
SHOULD TAPER OFF AS A SIGNIFICANT DRY SLOT JUST OFFSHORE MOVES INLAND
WITHIN THE NEXT 1-3 HOURS.
IN ADDITION TO THE HEAVY RAIN THERE IS STRONG WIND BEGINNING TO MOVE
ONSHORE. GUSTS NEAR 70 MPH HAVE BEEN REPORTED ALONG THE COAST...WITH
79 MPH REPORTED IN THE PAST HOUR AT ROCKHOUSE RAWS IN THE COAST
RANGE. AM SOMEWHAT CONCERNED WITH THE DRY SLOT RACING ONSHORE AS IT
IS...THIS MAY HELP THE STRONGER WINDS JUST ABOVE THE VALLEY TO MIX
DOWN TO THE VALLEY FLOOR. WILL INVESTIGATE FURTHER AND MAKE A
DECISION SHORTLY ON WHETHER TO UPGRADE THE WIND ADVISORY TO A HIGH
WIND WARNING FOR THE WILLAMETTE VALLEY.
EVERYTHING WITH THE NEXT SYSTEM TUE/TUE NIGHT APPEARS ON TRACK...AND
12Z MODELS TRENDED TOWARD A VERY DEEP LOW APPROACHING THE PAC NW
COAST BY THURSDAY. WILL OBVIOUSLY MONITOR ALL THIS CLOSELY AND
DISCUSS FURTHER WITH THE AFTERNOON DISCUSSION. WEAGLE
.SHORT TERM...TODAY THROUGH WEDNESDAY...A STRONG LOW ROTATED
NORTHEAST INTO B.C. OVERNIGHT AND BROUGHT STORM FORCE WINDS TO THE
COASTAL WATERS...HIGH WINDS TO THE COAST AND COAST RANGE...AND HEAVY
RAIN TO THE NORTHERN HALF OF OUR FORECAST AREA. THE ASSOCIATED
FRONTAL BOUNDARY WAS TRYING TO PUSH SOUTH OF THE COLUMBIA RIVER...
AND WINDS ON THE SOUTH WASHINGTON COAST AND IN THE WILLAPA HILLS HAVE
EASED A BIT. WINDS REMAIN STRONG SOUTH OF THE COLUMBIA RIVER. RAINS
CONTINUE UNABATED OVER MUCH OF OUR FORECAST AREA.
THE WARM FRONT WITH THE NEXT STRONG WAVE/LOW WILL CONTINUE TO MOVE
INTO OUR FORECAST AREA THROUGH TODAY WITH LITTLE OR NO BREAK IN THE
RAINFALL. THE MODELS INDICATE THE STRONG WINDS WILL WORK THEIR WAY
BACK NORTH ONTO THE SOUTH WASHINGTON COAST AND INTO THE WILLAPA HILLS
LATER THIS MORNING AND THIS AFTERNOON...AND HAVE SHIFTED THE HIGH
WIND WARNING IN THAT AREA TO COVER THOSE HOURS WHILE THE HIGH WIND
WARNING SOUTH OF THE COLUMBIA RIVER AND THE INLAND WIND ADVISORY ARE
UNCHANGED.
THE MODELS SAY THE PRECIPITATION FIELD WILL FINALLY PUSH SOUTH OF THE
AREA THIS EVENING AND GIVE US A BRIEF BREAK IN THE HEAVY
PRECIPITATION. PRIOR TO THAT...EXPECT A FEW RIVERS WILL REACH FLOOD
STAGE LATER TODAY...INCLUDING THE GRAYS...NEHALEM...AND WILSON... AND
THE UPPER TUALATIN INLAND. THE CURRENT FLOOD WATCH IS STILL VALID.
THE FRONTAL BOUNDARY THAT MOVES SOUTH THIS EVENING IS FORECAST TO
LIFT BACK NORTH AS A WARM FRONT LATER TONIGHT AND EARLY TUESDAY. THE
ASSOCIATED COLD FRONT WILL THEN SAG SOUTH INTO SOUTHWEST WASHINGTON
AND NORTHWEST OREGON TUESDAY AND STALL TUESDAY NIGHT INTO EARLY
WEDNESDAY AS SECOND WAVE/LOW MOVES INLAND ALONG THE FRONT. EXPECT A
GOOD CHANCE AT TWO MORE PERIODS OF HIGH WINDS ALONG THE COAST WITH
THIS SYSTEM...AS WELL AS MORE HEAVY RAIN THAT COULD VERY EASILY
RESULT IN MORE FLOODING.
THIS WHOLE PATTERN IS BEING DRIVEN BY A VERY ACTIVE ZONAL JET ACROSS
THE PACIFIC THAT HAS PRECIPITABLE WATER VALUES WELL OVER AN INCH AND
JET LEVEL WIND SPEEDS OF AROUND 150 KT.
RAINFALL TOTALS FROM THIS PAST SUNDAY NIGHT THROUGH NEXT FRIDAY COULD
REACH 12 INCHES IN THE CASCADES AND THE COASTAL MOUNTAINS... WITH
PERHAPS 3 TO 6 INCHES IN THE VALLEYS...SO THIS IS LOOKING LIKE A VERY
HYDROLOGICALLY ACTIVE WEEK FOR SOUTHWEST WASHINGTON AND NORTHWEST
OREGON.
SNOW LEVELS STILL APPEAR A BIT LOW IN EASTERN SKAMANIA COUNTY AND
ALONG THE NORTH OREGON CASCADE CREST REGION...SO WILL KEEP THE SNOW
ADVISORIES FOR A FEW MORE HOURS THIS MORNING BEFORE WARMER AIR ALOFT
WITH THE INCOMING WARM FRONT OVERWHELMS THE TRAPPED COLDER AIR.
TOLLESON
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...
WEDNESDAY NIGHT THROUGH SUNDAY...MODELS ARE IN GOOD AGREEMENT THAT AN
ACTIVE WEATHER PATTERN WILL CONTINUE INTO NEXT WEEKEND. AS A
RESULT...POPS WERE GENERALLY PLACED NEAR TO ABOVE CLIMO FOR MOST OF
THE EXTENDED PERIOD. THE EC AND GFS HAVE COME INTO BETTER AGREEMENT
EARLY IN THE EXTENDED PERIOD...BOTH DEPICTING A DEEP LOW PRESSURE...
APPROXIMATELY 970MB...MOVING NORTHEASTWARD TOWARDS THE NORTHERN TIP
OF VANCOUVER ISLAND. THE ATTENDANT OCCLUSION WILL MOVE EASTWARD INTO
THE REGION AND BRING ANOTHER ROUND OF RAIN...AND POSSIBLY SOME WINDY
CONDITIONS TO THE REGION WEDNESDAY NIGHT AND THURSDAY. MODELS HAVE
FLUCTUATED SOMEWHAT WILDLY ON HOW THEY HANDLE THIS SYSTEM OVER THE
PAST SEVERAL MODEL RUNS SO CONFIDENCE IS STILL FAIRLY LOW IN HOW THIS
SYSTEM WILL IMPACT THE REGION.
EITHER WAY...SNOW LEVELS SHOULD DROP FAIRLY QUICKLY INTO THE 3500-
4000 FT RANGE BEHIND THE FRONT ON THURSDAY AND FRIDAY. DEPENDING ON
THE TRACK OF THE LOW PRESSURE...THE CASCADES MAY END UP WITH SOME
DECENT SNOW DURING THIS PERIOD. MODELS SEEM TO BE TRENDING TOWARDS
THE IDEA THAT THE AREA MAY TEMPORARILY DRY OUT LATE FRIDAY BEFORE
ANOTHER STORM SYSTEM HITS THE PACIFIC NORTHWEST SATURDAY-ISH. /NEUMAN
