AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
330 PM PST SAT JAN 19 2008

.SYNOPSIS...AN UPPER LEVEL TROUGH WILL CONTINUE TO PASS THROUGH WA
THIS EVENING WITH SHOWERS DECREASING AFTER MIDNIGHT. STRONG
NORTHEASTERLY WINDS WILL BLOW THROUGH THE FRASER RIVER VALLEY OF BC
SUNDAY MORNING BRINGING COOLER AIR INTO WESTER WA AND VERY WINDY
CONDITIONS ACROSS THE NORTH. DRY BUT COOL CONDITIONS WILL PERSIST
THROUGH THE MIDDLE OF THE WEEK...THEN MORE RAIN AND SNOW IS POSSIBLE
THURSDAY THROUGH SATURDAY.

&&

.SHORT TERM...UPPER LEVEL LOW MAKING ITS WAY ACROSS WA THIS EVENING
WITH SCATTERED TO NUMEROUS SHOWERS ON THE RADAR. WATER VAPOR LOOP
SHOWS THE TROUGH AXIS RIGHT ACROSS THE CASCADES HEADING E. ONE
CONCERN FOR THE EVENING IS THE CHANCE FOR A LITTLE BIT OF LOWLAND
SNOW. KBLI SWITCHED TO SNOW BRIEFLY THIS AFTERNOON AS WINDS TURNED
TO NORTHERLY. TEMPS ACROSS THE REMAINDER OF THE INTERIOR WILL BE
RIGHT ON THE BORDER SO MENTIONED THE POSSIBILITY OF SOME SNOW
SHOWERS IN THE EVENING....ESPECIALLY IF WINDS ACROSS THE REST OF THE
INTERIOR ALSO SWITCH OVER TO THE NORTH SOONER THAN EXPECTED. PRECIP
ALSO IS STARTING TO FOCUS INTO BANDS WHICH WOULD ALSO MAKE THINGS
INTERESTING IF HEAVIER RAIN/SNOW SHOWERS DEVELOP.

BIG STORY FOR SUNDAY IN THE FRASER VALLEY OUTFLOW THAT THE MODELS
HAVE BEEN SHOWING OVER THE PAST FEW DAYS. THE UPPER LEVEL TROUGH
WILL SHIFT TO THE SE OVER EASTERN OREGON SUN MORNING AS A STRONG SFC
HIGH ACROSS INTERIOR BC SAGS SOUTHWARD. PRES GRADIENT FROM
BELLINGHAM TO WILLIAMS LAKE BC INCREASES TO -19 MB WITH STRONG NE
FLOW SPEWING OUT OF THE FRASER RIVER VALLEY INTO WESTERN WA. THE
EAST WINDS WILL ALSO FAN OUT THROUGH THE STRAIT OF JUAN DE FUCA
MAKING FOR A PRETTY BLUSTERY DAY ACROSS THE NORTH. WENT AHEAD AND
ISSUED WIND ADVISORY FOR NORTH INTERIOR...SAN JUANS AND WESTERN
STRAIT FOR NE TO E WINDS AT LEAST 25 TO 35 WITH GUST UP TO 55 MPH
POSSIBLE. AS FOR THE TEMPS...MOST AREAS WILL STRUGGLE TO GET OUT OF
THE 30S ON SUNDAY...BUT SKIES WILL BE IMPROVING IN THE AFTERNOON FOR
A MOSTLY SUNNY DAY. MOST LIKELY THE COLDEST TEMPS OF THE SEASON WILL
BE OVERNIGHT SUNDAY WITH MORNING LOWS ON MARTIN LUTHER KING JR DAY
DOWN TO THE TEENS TO MID 20S. DRY AND COOL ON TUES AS WELL. 33

.LONG TERM...DRY AND COOLER WEATHER IS EXPECTED ACROSS WESTERN WA
THROUGH WEDNESDAY WITH LITTLE CHANGE TO THE PREVIOUS FORECAST. BY
THURSDAY...THE UPPER LOW THAT WAS OVER WA ON SAT WILL EVENTUALLY GET
PINCHED OFF INTO A CUTOFF LOW OFF THE CA COAST. MODELS DISAGREE WITH
WHERE THIS CUTOFF WILL VENTURE...EITHER EAST AS IT PHASES WITH
ANOTHER DEVELOPING TROUGH OR BACK NORTH TOWARD THE PAC NW. WILL NEED
TO WATCH HOW THIS EVOLVES AS DIFFERENT TRACKS MAY UPSET THE OVERALL
PATTERN. MODELS DO HINT AT A BROAD TROUGH DEVELOPING ACROSS THE AREA
THROUGH SATURDAY SO DID INTRODUCE CHANCE POPS ACROSS THE AREA. TEMPS
WILL STILL BE ON THE COOL SIDE WHICH WOULD MAKE THINGS REALLY
INTERESTING WITH THE POSSIBILITY OF MORE LOWLAND SNOW. 33

&&

.AVIATION...WITH LOW PRESSURE CENTERED NEAR THE CENTRAL PUGET SOUND
AREA...EXPECT NEARLY STATUS QUO LOW CLOUDS AND RATHER LOW
VISIBILITIES TO CONTINUE MUCH OF THE NIGHT. SHOWER ACTIVITY OVER THE
NORTH SOUND WILL GRADUALLY SHIFT SOUTH THROUGH THE SOUND LATE
TONIGHT. THERE IS THE RISK THAT PRECIPITATION WILL CHANGE TO SNOW
OVERNIGHT WITH UP TO 1 INCH ACCUMULATION BETWEEN ABOUT MIDNIGHT AND
7 AM AS MODIFIED ARCTIC AIR BEGINS POURING OUT OF THE FRASER VALLEY
NE OF BELLINGHAM AND DUMPS SOUTH THRU THE SOUND. THE BEST CHANCE FOR
THE LIGHT ACCUMULATION IN THE SEATTLE AREA IS BETWEEN 2 AND 6 AM.
TEMPERATURES AT THE CHANGEOVER WOULD BE NEAR FREEZING. THE AIR MASS
WILL RAPIDLY DRY FROM THE NORTH EARLY SUN MORNING WITH SEVERE CLEAR
BY 16Z OVER MUCH OF THE AREA. NE WINDS IN THE FRASER OUTFLOW AREA
AND NORTH OF THE SAN JUANS WILL REACH 30 TO 40 KT AROUND 7 AM SUN
MORNING AND WILL CONTINUE THRU SUN NIGHT OR MON. ALBRECHT

&&

.MARINE...CONVERGING LOW LEVEL WINDS OCCURRING AT THIS TIME WITH LOW
PRESSURE SITTING OVER THE CENTRAL PUGET SOUND AREA. WIND WILL COME
AROUND TO N OVERNIGHT AS THE LOW DROPS S...AND WILL THEN RAPIDLY
RAMP UP TO GALE FORCE COAST...STRAIT AND NORTH INLAND WATERS EARLY
SUN MORNING AS BELLINGHAM-WILLIAMS LAKE PRESSURE GRADIENTS RISE TO
-18 MB. SCA WINDS ARE EXPECTED AT THE EAST ENTRANCE...ADMIRALTY
INLET AND PUGET SOUND/HOOD CANAL BEGINNING EARLY SUN. THESE STRONG
WINDS WILL CONTINUE THROUGH MUCH OF THE DAY MON. WINDS AND SEAS WILL
SUBSIDE LATER MON WITH LIGHT CONDITIONS TUE AND WED AS THE HIGH
DRIFTS SE AND WEAKENS. A RATHER STRONG PACIFIC STORM SYSTEM WILL
APPROACH VANCOUVER ISLAND THU. ALBRECHT

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
.GALE WARNING COAST...WEST ENTRANCE TO THE STRAIT...CENTRAL
  STRAIT...AND NORTHERN INLAND WATERS.
.SMALL CRAFT ADVISORY...EAST ENTRANCE TO THE STRAIT...ADMIRALTY
  INLET...AND PUGET SOUND AND HOOD CANAL.
