AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
910 AM PST FRI JAN 21 2011

.SYNOPSIS...A COLD FRONT WILL MOVE THROUGH WESTERN WASHINGTON TODAY.
WEAK HIGH PRESSURE WILL BUILD INTO THE REGION OVER THE WEEKEND.
FRONTAL SYSTEMS WILL PASS BY TO THE NORTH...BUT MOISTURE WILL
OCCASIONALLY BRUSH WESTERN WASHINGTON. AROUND THE MIDDLE OF NEXT
STRONG HIGH PRESSURE WILL BUILD OVER THE PACIFIC NORTHWEST.

&&

.SHORT TERM...RAIN WITH A COLD FRONT TODAY AND SHOWERS DECREASING
TONIGHT. MOST OF THE SHOWERS WILL BE IN THE CASCADES AND
FOOTHILLS...AND PROBABLY THE PSCZ AROUND THE METRO AREA TONIGHT. THE
FCST PROBABLY NEEDS SOME MORE PRECIP TNGT EAST OF I-5 AND INTO THE
SEATTLE AREA FOR THE POSSIBLE PSCZ...CHANGING THE FCST FOR A CHANCE
OF SHOWERS TO SCATTERED SHOWERS OR LIKELY POPS IS PROBABLY WHAT I
WILL DO. THERE WILL LIKELY BE RESIDUAL LOW LEVEL MOISTURE INTO
SATURDAY MORNING...SOME AREAS OF MORNING DRIZZLE SEEM A GOOD
BET...THEN FOR AFTERNOON PERHAPS A LITTLE SUNSHINE. THE FREEZING
LEVEL IN THE MOUNTAINS WILL DROP BEHIND THE COLD FRONT LATER TODAY
WITH THE 850MB TEMP FALLING A FEW DEGREES. THE SNOW LEVEL THIS
MORNING PROBABLY TAPERS FROM AROUND 4000 FEET IN THE NORTH AND NEAR
THE CREST...TO ABOUT 5500 FEET AT PARADISE...AND IT OUGHT TO FALL TO
ARND 3000 FEET THIS EVENING. 19

.LONG TERM...THERE IS ENOUGH RAIN SNEAKING INTO NW WA ON SUNDAY TO
THINK THE FCST IS TOO OPTIMISTIC. AND IN THE LATEST GFS HEIGHTS ARE
FALLING OVER THE REGION MONDAY AND I WOULD EXPECT ANOTHER DRIPPY DAY
AS A FNTL SYSTEM MOVG THRU B.C. BRUSHES WRN WA. THE UPPER RIDGE
CENTER BUILDS OVER THE PACNW NEXT WED AND THAT SHOULD MARK THE END
OF CLOUDY DRIPPY DAYS AS OFFSHORE FLOW DEVELOPS...THE 12Z GFS HAS A
1035MB HIGH CENTER OVER S.E. BRITISH COLUMBIA BY THE MIDDLE OF NEXT
WEEK. 19

&&

.HYDROLOGY...FLOOD WARNINGS REMAIN IN EFFECT FOR MINOR FLOODING ON
THE GREEN AND CEDAR RIVERS FOR THE NEXT FEW DAYS DUE MAINLY TO
UPSTREAM RESERVOIRS BEING DRAINED. RAINFALL TODAY AND SATURATED
SOILS WILL CONTINUE TO GIVE AN ELEVATED THREAT OF MUDSLIDES. FRONTAL
SYSTEMS WILL BRUSH THE AREA SUN NITE THRU MONDAY NIGHT AS THEY MOVE
TO THE NORTH...BUT THAT IS NOT LIKELY TO BE SIGNIFICANT. THEN AROUND
THE MIDDLE OF NEXT WEEK THE RIDGE IS LIKELY TO BUILD FOR A PERIOD OF
DRY WEATHER. SO FLOODING IS UNLIKELY THROUGH NEXT WEEK. 19

&&

.AVIATION...STRONG AND MOIST NORTHWEST FLOW ALOFT WILL CONTINUE
TODAY...WITH DRYING COMMENCING AFTER 00Z. A WEAK WARM FRONT LIES
OVER THE AREA WITH SOUTHEAST WINDS. A COLD FRONT WILL MOVE INLAND
THIS AFTERNOON...GIVING STRONG ONSHORE SURFACE FLOW.

WIDESPREAD IFR CEILINGS AND RAIN HAVE DEVELOPED IN THE WARM FRONT.
VISIBILITIES ARE GENERALLY 3-5SM IN RAIN AND FOG. THESE CONDITIONS
ARE LIKELY TO PERSIST UNTIL THE COLD FRONT MOVES THROUGH THIS
AFTERNOON.

KSEA...DISCUSSION ABOVE APPLIES. CEILINGS AND VISIBILITIES ARE
LIKELY TO STAY WHERE THEY ARE UNTIL THE AFTERNOON. SOUTHEAST WINDS
6-10 KT THROUGH THIS MORNING. SOUTHWEST WINDS 10-15 KT THIS
AFTERNOON AND EVENING...TAPERING OVERNIGHT. HANER

&&

.MARINE...A COLD FRONT WILL SWEEP THROUGH THIS AFTERNOON WITH
ONSHORE FLOW FOLLOWING. MODELS SHOWED STRONG WESTERLIES DOWN THE
STRAIT BUT NOT MUCH WIND ELSEWHERE...EVEN WITH STRONG ONSHORE
GRADIENTS DEVELOPING. CURRENT FORECAST OF 20-30 KT WESTERLIES IN THE
STRAIT LOOKS GOOD BUT THERE IS AN OUTSIDE CHANCE OF GALE FORCE
WESTERLY WINDS THIS EVENING IN THE CENTRAL AND EASTERN STRAIT. IN
DEFERENCE TO THE FORECAST GRADIENTS HAVE INDICATED SMALL CRAFT
ADVISORY SOUTHWEST WINDS ALL OTHER AREAS DURING THE PERIOD 21Z-03Z.
SHOULD BE BREEZY IN PLACES THIS AFTERNOON AND EVENING.

WINDS DIMINISH RAPIDLY TONIGHT AND SHOULD BE LESS THAN 20 KT OVER
ALL WATERS SATURDAY AS SURFACE HIGH PRESSURE BUILDS. HIGH PRESSURE
WILL REMAIN OVER THE AREA THROUGH THE FIRST PART OF NEXT WEEK.

HIGH TIDES WILL BE VERY HIGH FOR THE NEXT THREE DAYS BUT WITH HIGH
ATMOSPHERIC PRESSURE RATHER THAN LOW...TIDAL ANOMALIES WILL BE ZERO
OR EVEN NEGATIVE SO MINOR TIDAL OVERFLOW IS NOT EXPECTED.

EBB CURRENTS ARE RUNNING VERY STRONG OR STRONG THROUGH
SUNDAY...WHICH WILL ENHANCE ROUGH BAR CONDITIONS. HANER

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...FLOOD WATCHES AND/OR WARNINGS FOR PORTIONS OF THE FORECAST AREA.

PZ...SMALL CRAFT ADVISORY ALL WATERS.
     SMALL CRAFT ADVISORY FOR ROUGH GRAYS HARBOR BAR.
