AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 PM PDT TUE OCT 30 2012

.SYNOPSIS...A FRONTAL SYSTEM WILL BRING SIGNIFICANT RAINFALL TO
WESTERN WASHINGTON TONIGHT AND WEDNESDAY. AN UPPER TROUGH WILL MOVE
INLAND IN THE WAKE OF THE FRONT WEDNESDAY NIGHT AND THURSDAY FOR
DECREASING SHOWERS. DRY WEATHER IS LIKELY ON FRIDAY BUT ANOTHER
FRONTAL SYSTEM WILL BRING MORE WET WEATHER THIS WEEKEND. SHOWERS
WILL CONTINUE INTO EARLY NEXT WEEK.

&&

.SHORT TERM...LATEST RADAR LOOP THIS AFTERNOON INDICATES MODERATE
RAINFALL HAS OVERSPREAD ALL OF WRN WA. LOCALLY HEAVY RAIN WAS
OCCURRING ALONG THE S/SW FACING SLOPES OF THE OLYMPICS AND
CASCADES...AND ALSO ALONG THE LOWER COASTAL AREAS. AMOUNTS THE PAST
6 HOURS HAVE EXCEEDED 1 INCH IN A FEW PRECIP GAGE SPOTS NEAR THE SW
SLOPE OF THE OLYMPICS AND ALSO THE CASCADES. S/SW 850 MB FLOW OF
40-50 KT BEHIND THE WARM FRONT TONIGHT WILL ENHANCE RAINFALL RATES
FURTHER. RAINFALL AMOUNTS OF 2-4 INCHES...LOCALLY HIGHER ALONG
FAVORED SLOPES BY WEDNESDAY AFTERNOON APPEARS ON TRACK. 1-2 INCHES
ACROSS THE REMAINING LOWLANDS MAY ALSO CAUSE SOME LOCALIZED URBAN
AND SMALL STREAM FLOODING. FOLIAGE SHOULD BE CLEARED AS DRAINAGES
ARE LIKELY TO CLOG OVER THE NEXT 24 HOURS. SEE THE HYDRO SECTION
BELOW AND ALSO THE LATEST FLOOD STATEMENT FOR FURTHER DETAILS.

THE UPPER TROUGH OFFSHORE AND FRONTAL BAND OVER THE AREA WILL BECOME
MORE N/S ORIENTED BY WEDNESDAY AFTERNOON. SLY FLOW AT 850 MB WILL
WEAKEN AND RAINFALL RATES WILL EASE OFF ACROSS MOST THE
AREA...EXCEPT SLOWER TO TAPER OFF OVER S FACING SLOPES OF THE
OLYMPICS. THE ENTIRE UPPER TROUGH COMPLEX MOVES ACROSS THE AREA
WEDNESDAY NIGHT AND E OF WRN WA THURSDAY. THERE WILL BE SHOWERS
ACROSS WRN WA AS THE TROUGH PASSES AND ALSO WITH POST FRONTAL
ONSHORE FLOW THURSDAY.

.LONG TERM...A WEAK RIDGE WILL TRAVERSE THE AREA FRIDAY. MODELS SHOW
SPOTTY LIGHT QPF BUT GIVEN THE SPACE BETWEEN SYSTEMS I DECIDED TO GO
DRY FOR THE INTERIOR LOWLANDS. KEPT SOME LOW CHANCE POPS ON THE
COAST AND MOUNTAINS. MODELS VARY ON THE STRENGTH OF THE NEXT FRONTAL
SYSTEM TO AFFECT THE AREA. THE GFS/ECMWF DO AGREE ON BRINGING A
DECAYING FRONT INTO THE AREA FRIDAY NIGHT AND SATURDAY.
HOWEVER...HOW MUCH PRECIPITATION MAKES IT INLAND IS QUESTIONABLE.
CHANCE POPS SEEM APPROPRIATE FOR NOW. A TRAILING FRONT WILL HANG UP
SOMEWHERE NEAR THE AREA SUNDAY INTO MONDAY. AGAIN...MODELS VARY ON
EXACTLY WHERE THIS FRONTAL BAND HANGS UP BUT THERE IS GENERAL
CONSENSUS ON A WETTER PATTERN RETURNING. THIS SYSTEM SHIFTS E BY
TUESDAY SO EXPECT RAIN TO TAPER TO SHOWERS.  MERCER

&&

.HYDROLOGY...A HALF TO 1.5 INCHES HAVE FALLEN THE PAST 6-8 HOURS IN
SPOTS SUSCEPTIBLE TO S/SW FLOW. ANOTHER 2-3 INCHES IS LIKELY THROUGH
TONIGHT IN THESE AREAS AS 850 MB SW WINDS TO 40 KT CONTINUE
OROGRAPHIC ENHANCEMENT. THE SKOKOMISH RIVER IN MASON COUNTY APPEARS
TO BE THE MOST LIKELY RIVER TO REACH MINOR FLOOD STAGE TONIGHT.
THERE ARE ALSO A RIVERS IN THE N/CENTRAL CASCADES THAT COULD COME
NEAR OR BARELY EXCEED FLOOD STAGE. THE
SKAGIT...NOOKSACK...SNOQUALMIE NEAR THE FALLS...AND PUYALLUP AT
ORTING RIVERS ALL HAVE SOME RISK OF MINOR FLOODING LATER TONIGHT AND
WEDNESDAY. SEE THE LATEST HYDRO STATEMENT FOR DETAILS.

A LULL OR BREAK IN RAINFALL IS EXPECTED THURSDAY AND FRIDAY. THIS
WILL ALLOW WATERS TO RECEDE. ANOTHER FRONT WILL AFFECT THE AREA THIS
WEEKEND BUT THE THREAT OF FLOODING IS HIGHLY UNCERTAIN. CONTINUE TO
MONITOR FORECASTS.

BY EARLY NEXT WEEK A COOLER AND SHOWERY TROUGH PATTERN DEVELOPS.
THIS WILL LIKELY PRECLUDE ANY FLOOD THREAT.  MERCER

&&

.AVIATION...MOIST STABLE AIR OVER WESTERN WA IN A WARM FRONT OVER
THE AREA. SOUTHWEST FLOW ALOFT. RAIN AT TIMES WITH AREAS OF LOW CIGS
AND POOR VSBY...THE MOUNTAINS AND A LOT OF THE LOWER TERRAIN WILL
REMAIN OBSCURED. THE NAM MODEL SHOWS THE RAIN BREAKING UP WED
AFTERNOON AND NIGHT...BUT WRN WA IS NOT LIKELY TO BE IN A COOLER
DRIER AIR MASS TIL THU. 19

KSEA...CONDITIONS WILL PROBABLY CONTINUE TO STAY IN THAT RANGE OF
2-5 MILES VSBY AND 005-015 FOR CIGS THROUGH TONIGHT AS BANDS OF RAIN
KEEP PUSHING NORTH THROUGH WESTERN WA AND THE FRONTAL SYSTEM REMAINS
STALLED OVER THE REGION. WITH A NLY OLM-BLI PRESSURE GRADIENT OF
-1.7MB AT 21Z CANNOT REALLY KEEP A SLY WIND IN THE FORECAST...LIGHT
AND VARIABLE TONIGHT A BETTER BET...BUT NOT LIKELY TO GO NLY WITH
THE WINDS SLY JUST ABOVE THE SURFACE. 19

&&

.MARINE...EASTERLY GRADIENT HAVE INCREASED AND UIL-BLI WAS -4.2MB
AND TATOOSH HAD EAST 25KT AT 2PM. SMALL CRAFT ADVISORY SE TO SOUTH
WINDS 15 TO 25 KT ARE FCST TONIGHT FOR THE COASTAL WATERS. THE
FRONTAL SYSTEM WILL REMAIN STALLED OVER WESTERN WASHINGTON TONIGHT
AND WED. THE FRONT WILL MOVE INLAND WED NITE OR THU WITH PARENT LOW
FILLING AND DISSIPATING BEFORE IT REACHES THE COAST THU. 19

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...FLOOD WATCHES IN EFFECT FOR PORTIONS OF WESTERN WASHINGTON.
