AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
909 PM PDT SAT MAR 31 2012
.SYNOPSIS...A STRONG LOW OFF THE SOUTH OREGON COAST WAS MOVING
ONSHORE INTO SOUTHERN OREGON THIS EVENING...WITH A PIECE OF THE LOW
LIFTING NORTH ALONG THE OREGON COAST AND HELPING TO FUEL SHOWERS AND
A FEW THUNDERSTORMS IN NORTHWEST OREGON AND SOUTHWEST WASHINGTON.
THE WHOLE LOW WILL MOVE INLAND AND EASTWARD TONIGHT AND EARLY SUNDAY
WITH PLENTY OF SHOWERS AND SNOW IN THE CASCADES...FOOTHILLS...AND
COAST RANGE. ALSO SOME BREEZY TO WINDY CONDITIONS OVERNIGHT. A
SYSTEM BETWEEN 135W AND 140W WILL MOVE THROUGH OUR AREA SUNDAY
AFTERNOON AND SUNDAY EVENING WITH MORE VALLEY RAIN AND MOUNTAIN SNOW
AND LOCALLY BREEZY CONDITIONS. EXCEPT FOR THE NORTH COAST...WE MAY
SEE A BIT OF A LULL ON MONDAY BEFORE THE NEXT FRONT MOVES IN LATER
MONDAY NIGHT AND ESPECIALLY ON TUESDAY. THE PARENT UPPER LOW WILL
LINGER OVER OUR AREA FOR SHOWERS AND POSSIBLY SOME INSTABILITY
DURING THE MID WEEK PERIOD.
&&
.SHORT TERM...THE MAIN FRONT WITH THE CURRENT SYSTEM MOVED INLAND
AND EAST OF OUR AREA EARLIER TODAY. THE MAIN STRONG SURFACE LOW WAS
TO OUR SOUTH AND WAS MOVING ONSHORE INTO SOUTHERN OREGON. THIS LOW
PRODUCED WINDS WELL OVER 60 MPH TO OUR SOUTH. A PIECE OF THIS SYSTEM
EXTENDED NORTH ALONG OUR COAST THIS AFTERNOON AND EVENING...WITH A
BAND OF CONVECTION LIFTING NORTH THAT HAD SOME 40 TO 45 KT WIND GUSTS
ASSOCIATED WITH IT ALONG THE COAST. WE THEN SAW A COUPLE OF DECENT
THUNDERSTORMS OR CONVECTIVE CELLS LIFT NORTH THROUGH OUR AREA...AND
HAD A REPORT OF DIME SIZED HAIL IN NORTH PLAINS. THE PRECIPITATION
IS CURRENTLY BECOMING MORE WIDESPREAD AS THE OFFSHORE LOWER PRESSURE
MOVES ONSHORE AND THROUGH OUR AREA OVERNIGHT...THOUGH THERE REMAINS
SOME EMBEDDED HEAVIER SHOWERS.
AS THIS MOVES THROUGH OVERNIGHT...WINDS WILL SHIFT TO WESTERLY ACROSS
OUR FORECAST AREA...AND COULD BE RATHER STRONG OVERNIGHT. GUSTS TO 50
MPH NEAR THE COAST AND 35 TO 40 MPH INLAND ARE NOT OUT OF THE
QUESTION ON THE BACKSIDE OF THIS LOW.
SNOW LEVELS WILL BE DROPPING INTO THE COAST RANGE AND THE CASCADE
FOOTHILLS...THOUGH ONLY LIGHT ACCUMULATIONS IF THAT ARE EXPECTED IN
THE COASTAL PASSES. WILL CONTINUE THE SNOW ADVISORY FOR THE CASCADES
OVERNIGHT AS WELL WHERE MORE SIGNIFICANT SNOW IS EXPECTED.
AFTER THE SHOWERS BEGIN TO EASE SUNDAY MORNING...THE NEXT SYSTEM OUT
BETWEEN 135W AND 140W WILL MOVE IN SUNDAY AFTERNOON AND EVENING FOR
MORE VALLEY RAIN AND MOUNTAIN SNOW...POSSIBLY SOME SNOW AGAIN DOWN
INTO THE FOOTHILLS AND COASTAL MOUNTAINS. THIS PRECIPITATION SHOULD
MOVE EAST BY MONDAY MORNING AS THIS SYSTEM MOVES OFF TO THE EAST.
THE NEXT FRONT BEGINS TO APPROACH MONDAY...BUT LOOKS TO ONLY REACH
PERHAPS THE NORTH COAST ON MONDAY. MOS STATISTICAL GUIDANCE SUGGESTS
WE COULD GET CLOSE TO 60 ON MONDAY IN THE INLAND VALLEYS IF THE
FRONT STAYS NEAR THE COAST...AND THIS WOULD BE A WELCOME CHANGE TO
OUR RECENT INCLEMENT WEATHER. TOLLESON
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...
TUESDAY EVENING THROUGH EARLY SATURDAY...A BROAD UPPER TROUGH
OFFSHORE APPROACHES THE PACIFIC NORTHWEST AND MODELS CONTINUE TO
AGREE THE TROUGH WILL SHIFT INLAND BY MIDWEEK. A RELATED FRONT SHIFTS
OVER THE CWA MONDAY NIGHT AND TUESDAY...THEN PUTS THE NORTHWEST ON
THE COOL SIDE OF THE JET STREAM AND IN SHOWERY CONDITIONS THROUGH THE
END OF THE WEEK. AS A RESULT THERE MAY BE SOME DRYING TIME OPENING UP
FOR THE ALREADY SATURATED CWA. AT THE END OF THE WEEK MODELS BRING AN
UPPER RIDGE OVER THE AREA FOR A POSSIBLY DRY WEEKEND...THOUGH IT
LOOKS AS IF THE UPPER RIDGE COULD BE A RELATIVELY TEMPORARY CHANGE AS
MODELS SHOW A DEEP LOW MOVING TO THE COAST RIGHT ON THE HEELS OF THE
RIDGE. KELSON
&&
.HYDROLOGY...RIVERS CONTINUE TO RECEDE...THANKS IN PART TO MUCH LESS
RAINFALL OVER REGION TODAY. DROPPED THE WARNINGS ON THE REMAINING
COASTAL RIVERS. STILL HAVE FEW RIVERS IN THE WILLAMETTE VALLEY THAT
ABOVE FLOOD STAGE WHICH ARE EITHER HOLDING STEADY OR FALLING
SLOWLY...EXCEPT THE PUDDING RIVER WHICH IS SLOWLY CLIMBING. CURRENT
MODEL RUNS PROJECT THE LOWER WILLAMETTE MAINSTEM STAYING BELOW FLOOD
STAGE...BUT HAVE THE COLUMBIA RIVER JUST TOUCHING FLOOD STAGE ON
SUNDAY OR MONDAY. HAVE CANCELLED FLOOD WATCH FOR ALL AREAS...EXCEPT
FOR THE LOWER WILLAMETTE AND LOWER COLUMBIA DUE TO FORECASTS RUNNING
CLOSE TO FLOOD STAGE.
&&
.AVIATION...UNSTABLE SHOWERY AIR MASS CONTINUES TO IMPACT THE REGION
THIS EVENING. MOSTLY VFR CONDITIONS PREVAIL INTO EARLY TONIGHT...
WITH OCCASIONAL DROPS INTO MVFR OR LOWER IN HEAVIER SHOWERS. MAY SEE
MORE PREDOMINANT MVFR CONDITIONS AFTER MIDNIGHT AS A BRIEF PERIOD OF
STEADY RAIN MOVES ACROSS THE AREA IN THE BENT BACK OCCLUSION. SHOWERS
WILL RETURN EARLY SUNDAY AS THE CURRENT SYSTEM MOVES EAST OF THE
CASCADES...AND EXPECT A RETURN OF PREDOMINANT VFR CONDITIONS BY LATE
SUNDAY MORNING/EARLY AFTERNOON.
KPDX AND APPROACHES...OVERALL VFR CONDITIONS PREVAIL THROUGH SUNDAY.
MVFR CONDITIONS ALONG WITH GUSTY SOUTHERLY WINDS ARE POSSIBLE IN
HEAVIER SHOWERS AS A MORE UNSTABLE SHOWERY AIR MASS MOVES OVER THE
AREA THIS EVENING. SHOULD SEE STEADY RAIN AND MVFR CONDITIONS MOVE
THROUGH BETWEEN 06Z AND 10Z. BROWN/27
&&
.MARINE...AFTER A SHORT LULL IN WINDS THIS EVENING...WINDS BEHIND THE
SYSTEM WILL AGAIN INCREASE AFTER MIDNIGHT TO STRONG GALE FORCE AND
CONTINUE INTO EARLY SUNDAY MORNING. LOCALLY HIGHER GUSTS TO 45 KT ARE
POSSIBLE IN THE OUTER WATERS AROUND MIDNIGHT. WINDS WILL THEN
DECREASE BRIEFLY SUNDAY MORNING AHEAD OF THE NEXT SYSTEM...THOUGH
STAY ABOVE SMALL CRAFT MINIMUMS.
AS THE NEXT STRONG SYSTEM APPROACHES SUNDAY...WINDS WILL BACK AROUND
TO THE SOUTH AND INCREASE AGAIN TO STRONG GALES BY LATE SUNDAY
AFTERNOON. WIND GUSTS WILL INCREASE AFTER MIDNIGHT...WITH A CHANCE OF
GUSTS INTO STORM FORCE BY EARLY MONDAY MORNING ESPECIALLY OVER THE
NORTHERN WATERS. THE FRONTAL SYSTEM IS EXPECTED TO MOVE THROUGH THE
WATERS MONDAY EVENING WITH WINDS DECREASING SHARPLY BEHIND THE
BOUNDARY.
SEAS WILL CONTINUE TO INCREASE TO THE MID TEENS THROUGH TONIGHT
MAINLY DUE TO INCREASING WINDS. SEAS WILL CONTINUE IN THE MID TEENS
THROUGH SUNDAY...THEN SHOULD BUILD TO 18 TO 21 FEET BY MONDAY MORNING
WITH THE HIGHEST SEAS EXPECTED IN THE NORTHERN WATERS. BROWN/27
