AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
938 PM PST TUE DEC 4 2012

.SYNOPSIS...STRONG AND RELATIVELY MOIST WESTERLY FLOW ALOFT WILL
CONTINUE ACROSS THE REGION THROUGH FRIDAY. DISTURBANCES EMBEDDED
WITHIN THIS FLOW WILL KEEP THE THREAT OF SHOWERS GOING...AND WILL
RESULT IN LOCALLY GUSTY WINDS AT TIMES.

&&

.SHORT TERM...
THERE HAVE BEEN A FEW LIGHTNING STRIKES OVER THE NORTH COAST THIS
EVENING. THE STRIKES WERE EMBEDDED IN A LINE OF HEAVY SHOWERS THAT
MOVED ONTO THE COAST. VERY SMALL HAIL ALSO ACCOMPANIED THE HEAVY
RAIN. NWS DOPPLER RADARS SHOWED BANDS OF SHOWERS STILL MOVING ACROSS
THE AREA AT THIS TIME. THE HEAVIEST SHOWER BANDS WERE OVER THE COAST
AND THE STRAIT OF JUAN DE FUCA. LOOK FOR THE SHOWERS TO SLOWLY WIND
DOWN OVERNIGHT ONCE THE SHORT WAVE TROF EMBEDDED IN THE FAST
WESTERLIES MOVE INTO EASTERN WA.

STRONG AND RELATIVELY MOIST ZONAL FLOW ALOFT WILL PERSIST THROUGH
WED NIGHT. ANOTHER SHORT WAVE TROF EMBEDDED IN THE FLOW WILL CAUSE
THE SHOWERS TO INCREASE ACROSS THE AREA WED NIGHT AND CONTINUE
THROUGH THU. THE CASCADES WILL LIKELY RECEIVE 6 TO 11 INCHES OF NEW
SNOW WITH THIS SYSTEM...WITH LOCALLY HIGHER AMOUNTS POSSIBLE WHERE
THE PUGET SOUND CONVERGENCE ZONE /PSCZ/ SETS UP. THE PSCZ SHOULD
DEVELOP LATE THU MORNING OR EARLY THU AFTERNOON OVER ITS TYPICAL
LOCATION...NEAR THE KING/SNOHOMISH COUNTY LINE. THE PSCZ WILL
PROBABLY SHIFT INTO NORTH SEATTLE BY FRI MORNING.

THE FLOW ALOFT WILL BECOME NORTHWEST ON FRI AND ANOTHER FAST MOVING
SHORT WAVE WILL MOVE ACROSS THE REGION. THIS FEATURE WILL SERVE TO
KEEP THE SNOW PILING UP IN THE CASCADES.

.LONG TERM FROM THE PREV DISCUSSION...
THE ZONAL FLOW THIS WEEK IS FOLLOWED BY SOME RIDGING OVER THE
WEEKEND. SATURDAY MIGHT BY DRY WITH SOME SUN...BUT THE 12Z GFS HAD A
FRONT BREAKING UP IN A DIRTY RIDGE SITUATION BY SUNDAY. SNOW LEVELS
OUGHT TO TREND UP SAT-MON...PERHAPS A COUPLE THOUSAND FEET HIGHER
THAN THE CURRENT FORECAST...BUT PRECIP AMOUNTS WILL LIKELY NOT BE
HEAVY ENOUGH TO MAKE IT TOO LOUSY IN THE MOUNTAINS. THE 12Z ECMWF
HAD THE 1000-500 MB THICKNESS RISING FROM ARND 520 DM AT DAYBREAK
SATURDAY TO AROUND 546 DM A WEEK FROM NOW...AND 850 MB TEMPS THAT
WARM FROM -6C TO +2C OVER THAT PERIOD OF TIME. SO SKIING LOOKS VERY
GOOD FRI AND SAT...THEN MAYBE NOT SO IDEAL EARLY NEXT WEEK. 19

&&

.HYDROLOGY...
FLOODING CONTINUED ON THE SKOKOMISH RIVER AND THE CHEHALIS RIVER
NEAR GRAND MOUND AND AT PORTER. EXPECT THESE RIVERS TO BEGIN
GRADUALLY RECEDING OVERNIGHT OR DURING THE DAY WED. THE SKOKOMISH
RIVER WILL PROBABLY FALL BELOW FLOOD EARLIER THAN WHAT IS CURRENTLY
FORECAST.

HYDROLOGICAL SIGNIFICANT RAINFALL IS NOT EXPECTED THROUGH THE MIDDLE
OF NEXT WEEK...THEREFORE ADDITIONAL FLOODING OF AREA RIVERS IS NOT
ANTICIPATED.

&&

.AVIATION...AN UPPER TROUGH WILL MOVE ACROSS WESTERN WASHINGTON
TONIGHT...FOLLOWED BY WESTERLY FLOW ALOFT ON WEDNESDAY. AT THE
SURFACE...MODERATE ONSHORE FLOW TONIGHT WILL EASE ON WEDNESDAY. AIR
MASS MOIST AND UNSTABLE.

KSEA...SHOWERS WILL CONTINUE TONIGHT AS AN UPPER LEVEL DISTURBANCE
MOVES THROUGH...DECREASING ON WEDNESDAY. GUST SOUTHWEST WINDS 10-15
KNOTS TONIGHT WILL EASE ON WEDNESDAY AS ONSHORE FLOW DECREASES.
SCHNEIDER

&&

.MARINE...MODERATE ONSHORE FLOW WILL PRODUCE SMALL CRAFT ADVISORY
WINDS FOR ALL WATERS THROUGH WEDNESDAY MORNING. ONSHORE FLOW WILL
DECREASE ON WEDNESDAY WITH WINDS EASING BELOW SMALL CRAFT ADVISORY
LEVELS. SMALL CRAFT ADVISORY CONDITIONS FOR HAZARDOUS SEAS WILL
CONTINUE INTO WEDNESDAY NIGHT OVER THE COASTAL WATERS UNTIL WEST
SWELL SUBSIDE BELOW 10 FEET ON THURSDAY. A WEAK SURFACE TROUGH WILL
MOVE THROUGH THE WATERS ON THURSDAY...FOLLOWED BY A COLD FRONT
THURSDAY NIGHT AND FRIDAY. HIGH PRESSURE WILL BUILD OVER THE REGION
ON SATURDAY WITH OFFSHORE FLOW DEVELOPING.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...FLOOD WARNINGS OR WATCHES ARE IN EFFECT FOR THE SOUTHWEST
     PART OF THE FORECAST AREA.

     WINTER WEATHER ADVISORY IN EFFECT FOR THE CASCADES ABOVE
     2500 FEET UNTIL NOON WEDNESDAY.
