AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
855 PM PDT SAT MAR 14 2015

.SYNOPSIS...RAIN WILL SPREAD NORTH ACROSS THE AREA TONIGHT AND
SUNDAY. AN UNSETTLED SHOWERY WEATHER PATTERN WILL CONTINUE MONDAY
AND TUESDAY. DRY WEATHER IS LIKELY WEDNESDAY THROUGH FRIDAY BUT NEXT
WEEKEND LOOKS WET.

&&

.SHORT TERM...RAIN FROM THE FRONT WHICH MOVED ONSHORE EARLIER TODAY
IS CURRENTLY CONFINED TO THE FAR SOUTH PART OF THE FORECAST AREA AND
THE CENTRAL CASCADES WITH THE REMAINDER OF THE AREA BASICALLY DRY.
THIS AREA OF RAIN WILL GRADUALLY LIFT NORTH TONIGHT WITH RAIN
SPREADING TO ABOUT WHIDBEY ISLAND DURING THE EARLY MORNING HOURS
THEN INTO THE REMAINDER OF THE NORTHERN ZONES SUNDAY AS AN UPPER
SHORT WAVE LIFTS NORTH THROUGH THE AREA.

A SURFACE LOW WILL REACH THE AREA SUNDAY EVENING...POSSIBLY BRINGING
SOME WINDY CONDITIONS TO THE SOUTH PART OF THE FORECAST. THE LOW
WILL BE FILLING AS IT REACHES THE AREA WHICH SHOULD KEEP THE
STRONGEST WINDS SOUTH OF THE AREA.

RAIN WILL CHANGE TO SHOWERS AND TAPER MONDAY MORNING WITH GRADUAL
DRYING LATER MONDAY BEHIND THE UPPER SHORT WAVE. MONDAY NIGHT AND
THE FIRST HALF OF TUESDAY ARE LOOKING LARGELY DRY IN BETWEEN WEATHER
SYSTEMS. AN UPPER TROUGH WILL BRING AN INCREASING CHANCE OF RAIN
AGAIN LATER TUESDAY. SCHNEIDER

.LONG TERM...PREVIOUS DISCUSSION...BOTH THE GFS AND EURO SHOW A BIG
UPPER RIDGE OVER THE AREA ON WEDNESDAY. THE GFS IS DRY WHILE THE
EURO HAS SOME MYSTERY PRECIPITATION RIGHT IN THE RIDGE AXIS.
WEDNESDAY WILL PROBABLY BE DRY BUT HAVE KEPT SOME LOW POPS IN THE
FORECAST.

THE MODELS THEN DIVERGE WITH THE GFS REMAINING DRY THROUGH FRIDAY
AND THE EURO REMARKABLY WET STARTING THURSDAY AFTERNOON. FOR NOW
HAVE KEPT THURSDAY DRY AND KEPT LOW CHANCE POPS FRIDAY. THE DRY
WEATHER SEEMS LIKELY TO END AROUND SATURDAY AS BOTH MODELS HAVE
PRECIPITATION OVER THE AREA THOUGH THEY ARE COMPLETELY OUT OF PHASE.
CONFIDENCE IS PRETTY LOW IN ANY DETAILS. BURKE

&&

.HYDROLOGY...THE SKOKOMISH RIVER IS CREASING ABOUT A FOOT BELOW
FLOOD STAGE THIS EVENING. THERE WILL BE ANOTHER 12 HOURS OR SO OF
RAIN LATER TONIGHT AND SUNDAY BUT THIS IS NOT EXPECTED TO BE ENOUGH
TO CAUSE ANY FLOODING. FLOODING IS UNLIKELY ON AREA RIVERS FOR THE
NEXT SEVEN DAYS. SCHNEIDER

&&

.AVIATION...MOIST SW FLOW ALOFT WILL PERSIST OVER W WA THROUGH
SUNDAY NIGHT. A WARM FRONT OVER OREGON WILL SPREAD RAIN N ACROSS W
WA OVERNIGHT AS IT MOVES N. THE RAIN HAS ALREADY REACHED KCLS AT
02Z. CIGS ARE VFR OVER PUGET SOUND AT 03Z WITH LAYERS SCT-BKN030-040
BKN120. AS RAIN SPREADS N...CIGS WILL LOWER TO MVFR 09Z-15Z WITH
LOCAL IFR...AND VIS WILL LOWER TO MVFR.

RAIN AND LOW CIGS WILL CONTINUE INTO SUNDAY EVENING. A SURFACE LOW
WILL MOVE NE ACROSS THE CENTRAL WA COAST SUNDAY EVENING THEN
DISSIPATE OVER W WA LATE SUNDAY NIGHT. SLOW IMPROVEMENT IS EXPECTED
ON MONDAY AS A WEAK UPPER LEVEL RIDGE BUILDS OVER THE REGION.

KSEA...VFR CIGS THROUGH 10Z ALTHOUGH CIGS WILL BE LOWERING SOMEWHAT
QUICKLY AS WARM FRONT RAIN APPROACHES FROM THE S. A SCT-BKN025 LAYER
WILL BE AROUND THOUGH 10Z. AFTER 10Z CIGS WILL LOWER TO MVFR IN -RA
BR WITH OCCASIONAL IFR CIGS LIKELY. RAIN WILL CONTINUE THROUGH
SUNDAY. SURFACE WINDS WILL BE LIGHT AND VARIABLE UP THROUGH 08Z BUT
WILL SHIFT TO NE 4-8 KT BY 10Z...AND CONTINUE NE THROUGH SUNDAY. KAM

&&

.MARINE...THE SURFACE HIGH BUILDING OVER B.C. THIS EVENING HAS
WEAKENED THE PRESSURE GRADIENTS ACROSS W WA...SO WINDS HAVE SUBSIDED
BELOW ADVISORY LEVELS IN ALL AREAS. WINDS ARE LIGHT AND VARIABLE IN
MANY PLACES AT 8 PM BUT WILL SHIFT TO NORTHERLY OVERNIGHT AS THE
B.C. HIGH SETTLES IN.

THE BIG NEWS IS THE DEVELOPING LOW W OF THE N CA COAST THIS EVENING.
LAST NIGHTS GFS MODEL APPEARS TO HAVE BEEN THE BEST SOLUTION. MODELS
ARE IN FAIRLY GOOD AGREEMENT THAT THE LOW WILL TRACK NE TOWARD THE
CENTRAL WA COAST...DEEPENING TO AROUND 998 MB WHEN IT IS ABOUT 80 NM
W OF ASTORIA LATE SUNDAY AFTERNOON...THEN CROSS THE CENTRAL WA
COAST SUNDAY EVENING. THE LOW WILL THEN DISSIPATE RAPIDLY OVER W WA
LATE SUNDAY NIGHT. THE APPROACH OF THE LOW WILL GENERATE MODERATE
E-NE OFFSHORE FLOW ACROSS W WA...WITH AREAS OF SCA WINDS OVER THE
COASTAL WATERS...REACHING 30 KT AT TIMES. OVER THE N INTERIOR...NE
OUTFLOW WINDS COULD REACH SCA LEVELS OVER THE N INLAND WATERS AND
THE STRAIT OF JUAN DE FUCA. THE MODELS ARE STILL WORKING TOWARD
BETTER CONSENSUS SO THERE SHOULD BE A BETTER PICTURE ONCE THE 00Z
MESOSCALE MODELS AND THE 00Z ECMWF ARRIVE. KAM

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...SMALL CRAFT ADVISORY COASTAL WATERS.
