AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
926 PM PST WED FEB 29 2012

.SYNOPSIS...A COLD UPPER LOW OVER THE REGION WILL MOVE INTO THE
GREAT BASIN ON THURSDAY FOR IMPROVING CONDITIONS. EXPECT A WARM
FRONT TO BRUSH THE AREA LATE FRIDAY. HIGH PRESSURE ALOFT WILL
BUILD OVER THE REGION THIS WEEKEND FOR A TREND TOWARD DRIER AND
MILDER WEATHER. EXPECT A COOL AND UNSETTLED PATTERN TO RETURN
TO THE AREA THE FIRST PART OF NEXT WEEK.

&&

.SHORT TERM...
THE NAM MODEL DID A GOOD JOB IN PREDICTING THAT AN ORGANIZED BAND
OF SHOWERS WOULD DEVELOP OVER ISLAND COUNTY AND EXTEND ACROSS NRN
SNOHOMISH COUNTY THIS EVENING. THE LATEST WRF-GFS HAS ALSO PICKED
UP ON THIS. BOTH MODELS ESSENTIALLY AGREED THAT THE BAND OF SHOWERS
WILL SLIP SWD OVERNIGHT BEFORE QUICKLY MOVING ACROSS THE CENTRAL
PUGET SOUND DURING RUSH HOUR TRAFFIC TOMORROW MORNING. HAVE DECIDED
TO ISSUE A WINTER WEATHER ADVISORY FOR THE ADMIRALTY INLET AREA...
THE FAR WESTERN SNOHOMISH COUNTY LOWLANDS...AND THE CASCADE
FOOTHILLS THRU 9 AM PST THU. THE SEATTLE METRO AREA COULD RECEIVE
UP TO AN INCH OF SNOW THU MORNING BEFORE THE PRECIP TAPERS OFF.

MEANWHILE...THE COLD UPPER LOW PRESENTLY OVER THE REGION WILL MOVE
INTO THE GREAT BASIN THU AFTERNOON...WITH AN UPPER RIDGE FOLLOWING
IN ITS WAKE. EXPECT THE PRECIP THREAT TO BECOME MAINLY CONFINED TO
THE MOUNTAINS BY LATE IN THE DAY.

A WMFNT WILL BRING A CHANCE OF PRECIP TO THE CWA FRI AFTERNOON AND
NIGHT. THIS WILL BE FOLLOWED BY A WEAK CDFNT OR SFC TROF ON
SATURDAY. IN GENERAL...THE MODELS HAVE BEEN TRENDING TOWARD DRIER
FOR SUNDAY. IT APPEARED THAT MUCH OF THE CWA WILL BE DRY ON SUNDAY
EXCEPT FOR POSSIBLY THE N COAST AND FAR NW INTERIOR.

.LONG TERM FROM THE PREV DISCUSSION...
THE TREND OF AN UPPER LEVEL RIDGE CONTINUES FOR THE WEEKEND...BUT
CLOSE ENOUGH TO BE A DIRTY RIDGE.  STILL NOT SEEING IT BUILD NORTH
ENOUGH TO FEEL CONFIDENT ON TAKING OUT THE RAIN THREAT FOR THE
WEEKEND...ALTHOUGH I ALMOST PULLED THE TRIGGER ON DRYING OUT
SUNDAY.  IF MODEL TRENDS CONTINUE WILL LIKELY DRY OUT SUNDAY
TOMORROWS SHIFT.  WE COULD VERY WELL END UP WITH JUST SOME HIGH
CLOUDS AND MILD TEMPERATURES THIS WEEKEND.

MODELS HAVE BEEN RATHER CONSISTENT IN SWINGING A FAIRLY SHARP COLD
FRONT THROUGH THE REGION MONDAY ALTHOUGH THE DETAILS AS FAR AS
TIMING AND STRUCTURE HAVE VARIED SOME.  THE AIR MASS BEHIND THE
FRONT COOLS QUICKLY AND ENOUGH SO THAT THE THREAT FOR SNOW SHOWERS
RETURNS FOR LATE MONDAY THROUGH EARLY TUESDAY.  AFTER THAT THE
REGION REMAINS IN NW FLOW THAT GRADUALLY DRIES OUT.  CERNIGLIA

&&

.HYDROLOGY...FLOODING IS NOT EXPECTED THROUGH THE MIDDLE OF NEXT
WEEK.

&&

.AVIATION...A COLD UPPER LEVEL TROUGH OVER THE AREA TONIGHT WILL
SHIFT INLAND ON THURSDAY WITH DRIER NORTHWEST FLOW ALOFT DEVELOPING.
AT THE SURFACE...A BROAD AREA OF LOW PRESSURE OVER SOUTHERN BRITISH
COLUMBIA WILL WEAKEN AND SHIFT INLAND TONIGHT AND THURSDAY WITH
DECREASING ONSHORE FLOW. AIR MASS MOIST AND UNSTABLE BECOMING STABLE
WITH SOME DRYING ON THURSDAY.

A CONVERGENCE ZONE OVER SNOHOMISH COUNTY THIS EVENING WILL LIKELY
SLIDE SOUTH THROUGH THE METRO AREA AFTER MIDNIGHT TONIGHT...BEFORE
BREAKING UP OVER SOUTH KING OR PIERCE COUNTY THURSDAY MORNING. THE
AIR MASS IS COLD ENOUGH FOR RAIN TO MIX WITH SNOW IN HEAVIER SHOWERS
TONIGHT AND THURSDAY MORNING. SOME MID AND UPPER LEVEL DRYING IS
INDICATED ON THURSDAY AS NORTHWEST FLOW ALOFT DEVELOPS BUT THE LOW
LEVELS WILL LIKELY REMAIN FAIRLY MOIST.

KSEA...THE MAIN SHOWER THREAT IN THE NEAR TERM APPEARS TO BE BETWEEN
ABOUT 11Z-16Z WHEN THE CONVERGENCE ZONE IS EXPECTED TO DRAG THROUGH.
THERE WILL BE A RAIN/SNOW MIX THREAT DURING THIS TIME BUT
ACCUMULATIONS...IF ANY...ARE EXPECTED TO BE MINOR. SOUTH WIND 10 TO
15 KNOTS THIS EVENING...EASING AFTER MIDNIGHT. SCHNEIDER

&&

.MARINE...MODERATE ONSHORE FLOW WILL GRADUALLY EASE TONIGHT AND
THURSDAY AS A BROAD SURFACE LOW OVER SOUTHERN BRITISH COLUMBIA FILLS
AND SHIFTS INLAND. 14-18 FOOT SWELL OVER THE COASTAL WATERS WILL
GRADUALLY SUBSIDE TO BELOW 10 FEET THURSDAY AND THURSDAY NIGHT. A
FRONTAL SYSTEM WILL BRING ANOTHER ROUND OF SMALL CRAFT ADVISORY
SOUTHERLY WINDS TO MOST WATERS FRIDAY AND FRIDAY NIGHT WITH MODERATE
ONSHORE FLOW BEHIND THE FRONT SATURDAY. ANOTHER FRONTAL SYSTEM WILL
MOVE THROUGH THE WATERS AROUND SUNDAY NIGHT AND MONDAY. SCHNEIDER

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...WINTER WEATHER ADVISORY UNTIL 8 AM PST THURSDAY FOR THE
     CENTRAL CASCADES.

     WINTER WEATHER ADVISORY UNTIL 9 AM PST THURSDAY FOR THE
     ADMIRALTY INLET AREA...EAST PUGET SOUND LOWLANDS...AND
     EVERETT AND VICINITY.

PZ...SMALL CRAFT ADVISORIES ARE IN EFFECT FOR ALL WATERS.

     SMALL CRAFT ADVISORY FOR ROUGH BAR UNTIL 11 PM PST THURSDAY
     FOR THE GRAYS HARBOR BAR.
