AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND
925 AM PDT THU APR 23 2015

.SYNOPSIS...AFTER A FRONT BRINGS WIDESPREAD RAIN TO THE AREA
TODAY...EXPECT A COOL AND SHOWERY AIRMASS TO LINGER ACROSS THE AREA
ON FRIDAY AND SATURDAY. A PASSING WARM FRONT MAY BRING ADDITIONAL
LIGHT RAIN TO THE AREA ON SUNDAY...BUT IT LOOKS INCREASINGLY LIKELY
TO REMAIN DRY ACROSS THE AREA. HIGH PRESSURE SHOULD BRING DRIER AND
WARMER WEATHER EARLY NEXT WEEK...WITH MORE WET WEATHER LIKELY EITHER
LATE TUESDAY OR WEDNESDAY.

&&

.SHORT TERM...TONIGHT THROUGH SATURDAY...DOPPLER RADAR SHOWS A LARGE
SWATH OF RAIN MOVING EASTWARD INTO NORTHWEST OREGON THIS MORNING.
WHILE THIS HAS PRIMARILY BEEN VIRGA...THE LOWER ATMOSPHERE IS
BEGINNING TO MOISTEN ENOUGH THAT LIGHT RAIN IS STARTING TO REACH THE
SURFACE. ADDITIONAL SHOWERS OFF THE COAST OF OREGON AND WASHINGTON
APPARENT VIA KLGX RADAR ARE ASSOCIATED WITH THE MAIN FRONT THAT IS
CURRENTLY APPROACHING THE REGION. THIS FRONT AND SHOWER ACTIVITY
WILL SPREAD INLAND MIDDAY AND THIS AFTERNOON.

SUBSIDENCE BEHIND THE FRONT SHOULD PRODUCE A BREAK IN THE WET
WEATHER THIS EVENING AWAY FROM THE HIGHER TERRAIN.
HOWEVER...CONTINUING ONSHORE FLOW WILL ALLOW ADDITIONAL SHOWERS TO
SPREAD INTO THE AREA LATER TONIGHT. INSTABILITY WILL INITIALLY BE
SHALLOW ENOUGH THAT THESE SHOWERS WILL LIKELY REMAIN CONFINED TO THE
COAST...COAST RANGE AND CASCADES...BUT DEEPENING INSTABILTY...FROM
NORTH TO SOUTH...SHOULD EVENTUALLY ALLOW SHOWERS TO SPREAD INTO THE
WILLAMETTE AND LOWER COLUMBIA RIVER VALLEYS OVERNIGHT AND INTO
FRIDAY MORNING. DAYTIME HEATING SHOULD FURTHER ENHANCE SHOWER
ACTIVITY INLAND...BUT THUNDERSTORMS APPEAR VERY UNLIKELY.

SNOW LEVELS SHOULD LOWER SOLIDLY BELOW PASS LEVEL OVERNIGHT. WHILE
WINTER WX ADVISORY CRITERIA SNOW ACCUMULATIONS OF MORE THAN 6 INCHES
APPEAR UNLIKELY AT THE PASSES...THERE WILL LIKELY BE A PERIOD OF
HAZARDOUS TRAVEL OVER THE PASSES FRIDAY MORNING AND DURING ANY OF THE
INTENSE SHOWERS FRIDAY AFTERNOON. WILL PLAN ON HIGHLIGHTING THIS ON
SOCIAL MEDIA.

THE UPPER LEVEL TROUGH RESPONSIBLE FOR SENDING THE FRONT ACROSS THE
AREA TODAY...WILL SLOWLY MEANDER ACROSS THE AREA LATE FRIDAY NIGHT
AND SATURDAY BEFORE DIVING INTO THE GREAT BASIN. INSTABILITY WILL
DEEPEN AS A RESULT...AND EXPECT ADDITIONAL SHOWERS TO SPREAD INTO
THE AREA DURING THIS PERIOD. SOME SHOWERS MAY BE DEEP ENOUGH THAT A
FEW THUNDERSTORMS WILL BE POSSIBLE SO MAINTAINED THE SLIGHT CHANCE
OF THUNDER FOR THE MOST SUSCEPTIBLE LOCATIONS.

SHORTWAVE RIDGING SHOULD LEAD TO SHOWERS ENDING FAIRLY QUICKLY
SATURDAY EVENING...WITH ANOTHER COOL NIGHT IN STORE. MODELS CONTINUE
TO TREND DRIER FOR SUNDAY...BUT SOME ENSEMBLE MEMBERS ARE STILL
HANGING ONTO THE IDEA THAT A WARM FRONT WILL BRING RAIN TO THE AREA.
WILL EVALUATE THIS FURTHER WITH THE AFTERNOON FORECAST PACKAGE.
/NEUMAN

.LONG TERM...SUNDAY THROUGH WEDNESDAY...PREVIOUS DISCUSSION
BELOW...MADE VERY FEW CHANGES TO THE EXTENDED FORECAST...AS THE
OVERALL GIST OF THE FORECAST LOOKS TO BE ON TRACK. THE 00Z ECMWF
JOINED THE GFS/GEM IN STRENGTHENING THE UPPER RIDGE ENOUGH TO DRY OUT
THE VAST MAJORITY OF OUR FORECAST AREA SUNDAY THROUGH TUESDAY.
HOWEVER...THERE IS STILL A SIGNIFICANT NUMBER OF ENSEMBLE MEMBERS
WHICH DIFFER FROM THE 00Z OPERATIONAL GFS/ECMWF/GEM SOLUTIONS. THIS
UNCERTAINTY SHOWS IN GFS ENSEMBLE MOS FORECAST OUTPUT...WITH ENSEMBLE
AVERAGE POPS REMAINING IN THE 30S AND 40S AND A LARGE STANDARD
DEVIATION BETWEEN MEMBERS. THEREFORE WE DECIDED NOT TO ELIMINATE THE
MENTION OF RAIN FOR SUNDAY JUST YET. HOWEVER IF MODELS CONTINUE TO
TREND IN THE DIRECTION THEY HAVE BEEN MOVING...SUNDAY COULD BE A MILD
AND DRY DAY ACROSS MUCH OF OUR CWA...WITH A SWING BACK TO ABOVE
NORMAL TEMPS MON AND POSSIBLY TUE. MODEL CONSENSUS SHOWS NEXT FRONT
ARRIVING SOMETIME MIDWEEK...THOUGH TIMING DETAILS VARY BETWEEN
MODELS.  WEAGLE

&&

.AVIATION...MOSTLY VFR CONDITIONS AS A FRONTAL SYSTEM BRINGS LIGHT
RAIN AND OCCASIONAL MVFR CIGS TO THE REGION TODAY. EXPECT A PERIOD
OF WIDESPREAD MVFR CIGS AS THE FRONT MOVES ONSHORE LATE THIS
MORNING INTO THIS AFTERNOON AROUND 20Z THU-02Z FRI. COASTAL AREAS
LIKELY TO HAVE A LONGER PERIOD OF LOWERED FLIGHT CONDITIONS.
CONDITIONS IMPROVING WITH POST FRONTAL SHOWERS TONIGHT. HOWEVER
MOUNTAINS LIKELY BECOMING OBSCURED WITH AND AFTER THE FRONT MOVES
THROUGH.

KPDX AND APPROACHES...VFR WITH A MID CLOUD DECK AROUND 5000 TO
7000 FT WELL AHEAD OF THE FRONT IS EXPECTED TO LOWER TO MVFR
AROUND 2500 FEET BETWEEN 21Z THU AND 03Z FRI. EXPECT VFR TO
PREVAIL IN POST FRONTAL SHOWERS TONIGHT. BUT THERE MAY BE
LINGERING MVFR CONDITIONS TOWARD THE MOUNTAINS. /27

&&

.MARINE...A FRONTAL SYSTEM IS CURRENTLY PUSHING THROUGH THE
COASTAL WATERS THIS MORNING...SPREADING SMALL CRAFT ADVISORY WINDS
WITH GUSTS TO 25 KT SOONER THIS MORNING ACROSS THE WATERS. HAVE
CHANGED THE SMALL CRAFT ADVISORY TO WINDS TO REFLECT THE EARLIER
TIME FRAME...BUT WINDS STILL LOOK ON TRACK TO END BETWEEN 21Z THU
-00Z FRI. MODELS HAVE BACKED OFF A BIT ON THE STRENGTH OF A
COASTAL JET EXPECTED TO SET UP OVER THE INNER COASTAL WATERS
MIDDAY TODAY...WITH THE MAIN THREAT OVER THE NORTHERN INNER
WATERS. THE SOUTHERN INNER WATERS MAY HAVE A BRIEF PERIOD OF WINDS
GUSTING TO AROUND 25 KT AROUND MIDDAY. WINDS QUICKLY SIMMER DOWN
BY THE EVENING HOURS ONCE THE FRONT PUSHES INLAND.

SEAS WILL HAVE A DIP THIS MORNING AROUND 7 FT BUT PICK TO 10-12
FT TONIGHT INTO FRIDAY...PEAKING AROUND 13 FT LATE TONIGHT AND
FRI. BUOY 05 HAS BEEN AROUND 10 TO 11 FT THIS MORNING...WITH
CORRESPONDS WELL WITH MODELS. MODELS HAVE PUSHED BACK ON THE
TIMING OF THE INCOMING HIGHER SEAS UNTIL CLOSER TO 06Z FRI FOR THE
OUTER WATERS AND CLOSER TO 12Z FRI FOR THE INNER WATERS.

12Z MODELS HAVE ALSO TONED DOWN ON THE FRONTAL PASSAGES FRIDAY
NIGHT INTO SATURDAY...SO NOT EXPECTING ANY SIGNIFICANT STRONG WIND
THREAT UNTIL SUNDAY AS A WARM FRONT LIFTS OVER THE WATERS SUNDAY
MORNING.
