AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
910 AM PST TUE MAR 6 2012

.SYNOPSIS...HIGH PRESSURE WILL BUILD TODAY THROUGH THURSDAY FOR
SUNNIER AND DRIER WEATHER. RAIN WILL RETURN FRIDAY OR FRIDAY NIGHT
AS THE NEXT COLD FRONT ARRIVES. ONSHORE FLOW AND WET WEATHER AT
TIMES WILL CONTINUE INTO EARLY NEXT WEEK.

&&

.SHORT TERM...SNOW SHOWERS ARE WINDING DOWN ACROSS WESTERN WA THIS
MORNING AS EXPECTED. KATX RADAR JUST SHOWS LIGHT/WEAK ECHOES MAINLY
OVER KING CO...AND ALSO OVER THE EAST STRAIT OF JUAN DE FUCA.
ADDITIONAL SNOWFALL ACCUMULATIONS WILL BE LIGHT WITH JUST A FEW
FLURRIES /TRACE AMOUNTS/ EXPECTED. ELSEWHERE /OUTSIDE OF THE CENTRAL
SOUND/ SKIES HAVE CLEARED OUT WITH SUNNY TO MOSTLY SUNNY CONDITIONS.
NORTHWEST FLOW WILL KEEP TEMPS ON THE COOL SIDE TODAY WITH HIGHS
REMAINING IN THE LOWER 40S. ZONES WHERE UPDATED TO REFLECT RECENT
TRENDS ON THE SATELLITE AND RADAR.

SKIES WILL REMAIN MOSTLY CLEAR TONIGHT WITH TEMPS DOWN TO THE MID
20S TO LOWER 30S. MAY SEE FREEZING FOG IN THE SOUTH SOUND.

DRY WEATHER WILL CONTINUE ON WED AND THUR AS AN UPPER LEVEL RIDGE
BUILDS OVER THE PAC NW. TEMPS WILL MODERATE BY THU WITH AFTERNOON
HIGHS REACHING INTO THE 50S TO LOWER 60S. 33

.LONG TERM...PREVIOUS DISCUSSION...BOTH THE GFS AND ECMWF ARE A BIT
FASTER AND WETTER BRINGING A FRONTAL SYSTEM TO THE COAST FRIDAY AND
INLAND FRIDAY NIGHT. THE FORECAST HAS BEEN NUDGED IN THAT DIRECTION
FOR NOW. IF MODELS REMAIN CONSISTENT WITH THIS TREND...LATER SHIFTS
WILL PROBABLY BE INCREASING POPS FURTHER FOR THIS PERIOD. SATURDAY
WILL BE IN BETWEEN FRONTAL SYSTEMS BUT A WARM FRONT WILL BEGIN
AFFECTING THE AREA BY AFTERNOON. A FAIRLY VIGOROUS COLD FRONT WILL
MOVE THROUGH THE AREA SATURDAY NIGHT AND SUNDAY. ANOTHER FRONTAL
SYSTEM WILL BE APPROACHING ON MONDAY. ALL IN ALL...FRIDAY THROUGH
MONDAY LOOKS FAIRLY WET AND UNSETTLED. SCHNEIDER

&&

.HYDROLOGY...FLOODING IS UNLIKELY OVER THE NEXT 7 DAYS.

&&

.AVIATION...A BROAD UPPER LEVEL RIDGE CENTERED OFFSHORE ALONG 140W
COMBINED WITH AN UPPER LEVEL TROUGH OVER THE ROCKIES WILL MAINTAIN
DRY N FLOW ALOFT ACROSS W WA TODAY...BECOMING NW ON WEDNESDAY. A
SURFACE HIGH OVER SOUTHERN B.C. WILL MAINTAIN NORTHERLY LOW LEVEL
FLOW TODAY. LOW LEVEL FLOW WILL BECOME LIGHT WEDNESDAY AS THE
SURFACE HIGH SETTLES OVER THE AREA.

THE AIR MASS IS DRY AND STABLE...EXCEPT FOR CLOUDS AND SCATTERED
SHOWERS OVER EAST PUGET SOUND AND THE CENTRAL CASCADES...CAUSED BY
CONVERGENCE ZONE ACTIVITY THAT STILL HAS NOT COMPLETELY QUIT. THERE
ARE UPSLOPE FLOW CAUSED CLOUDS ALONG THE EASTERN STRAIT OF JUAN DE
FUCA BETWEEN PORT TOWNSEND AND PORT ANGELES CAUSED BY NORTHERLY FLOW
ACROSS THE STRAIT OF JUAN DE FUCA. THE REMAINDER OF THE LOWLANDS IS
CLEAR AND ONLY SCATTERED CLOUDS ARE EXPECTED TODAY. THE REMNANT OF
THE CONVERGENCE ZONE ACTIVITY SHOULD QUIT BY MIDDAY WITH CLOUDS
DISSIPATING THIS AFTERNOON. THE UPSLOPE FLOW ALONG THE STRAIT WILL
PROBABLY CONTINUE THROUGH THIS AFTERNOON. THERE WILL BE FURTHER
DRYING TONIGHT.

KSEA...LOW LEVEL MOISTURE LEFT OVER FROM A CONVERGENCE ZONE HAS
MOVED OVER KSEA AT 17Z...BUT THIS SHOULD BE SHORT-LIVED. EXPECT
CLEARING BY 20Z. SURFACE WINDS ARE WEAK WESTERLY BUT WITH N FLOW
SETTING UP THROUGH PUGET SOUND...THE SURFACE WINDS SHOULD SHIFT
AROUND TO NW-N 6-8 KT BY 20Z...THEN CONTINUE THROUGH THE EVENING. KAM

&&

.MARINE...A WEAK SURFACE HIGH OVER B.C. COMBINED WITH A WEAK SURFACE
TROUGH OVER W WA WILL MAINTAIN NORTHERLY FLOW ACROSS W WA TODAY.
BASED ON CURRENT OBSERVATIONS THE SCA FOR THE NORTH INLAND
WATERS...PUGET SOUND...AND THE W ENTRANCE WILL BE DROPPED AN HOUR
EARLY. WITH POINT WILSON STILL IN THE LOW 20S AND SMITH ISLAND JUST
UNDER...I WILL EXTEND THE SCA FOR THE E ENTRANCE AND ADMIRALTY INLET
UNTIL NOON. EVEN THOUGH THE OVERALL TREND IS FOR THE NORTHERLY
GRADIENT TO BE WEAKENING THIS AFTERNOON...IT IS POSSIBLE THAT THE
WINDS IN THE E ENTRANCE AND ADMIRALTY WILL REMAIN UP THIS
AFTERNOON...JUST OVER 20 KT...AND SOME SPOTS IN PUGET SOUND MAY POP
BRIEFLY OVER 20 KT SO A SHORT-FUSED SCA MAY BE NECESSARY.

N FLOW OVER THE COASTAL WATERS IS NOT EXPECTED TO EASE BELOW SCA
LEVELS UNTIL TONIGHT. AT LEAST THE W SWELL SHOULD SUBSIDE BELOW 10
FT ABOUT THE SAME TIME.

THE SURFACE RIDGE IS STILL EXPECTED TO SETTLE OVER THE AREA TONIGHT
AND WEDNESDAY FOR A PERIOD OF WEAK WINDS. THE NEXT FRONT WILL
APPROACH THE AREA THURSDAY WITH OFFSHORE FLOW INCREASING. THE MODELS
STILL DRAG THE FRONT SLOWLY ACROSS THE AREA FRIDAY...FOLLOWED BY A
STRING OF ADDITIONAL SYSTEMS INTO EARLY NEXT WEEK. KAM

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.

PZ...SMALL CRAFT ADVISORY COAST...EAST ENTRANCE...ADMIRALTY INLET.
     SMALL CRAFT ADVISORY GRAYS HARBOR FOR ROUGH BAR CONDITIONS.
