AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 AM PST SUN NOV 22 2009
.SYNOPSIS...A VIGOROUS FRONTAL SYSTEM IS MOVING THROUGH THE PACIFIC
NORTHWEST THIS MORNING. ITS SURFACE LOW MADE LANDFALL NEAR ASTORIA
OVERNIGHT AND IT WILL MOVE QUICKLY NORTHEAST ACROSS THE CASCADES
THIS MORNING. THE SYSTEM WILL BRING A COOL SHOWERY DAY WITH SNOW IN
THE MOUNTAINS. A WEAKER FRONT WILL MOVE THROUGH THE AREA MONDAY AND
MONDAY NIGHT...FOLLOWED BY WEAK FRONT LATE IN THE WEEK.
&&
.SHORT TERM...A VIGOROUS FRONTAL SYSTEM IS MAKING ITS THROUGH THE
PACIFIC NORTHWEST THIS MORNING...BRINGING SIGNIFICANT RAIN TO THE
LOWLANDS AND HEAVY SNOW TO THE MOUNTAINS. THE 989 MB SURFACE LOW
MADE LANDFALL NEAR ASTORIA AROUND 2 AM AND IT IS MOVING QUICKLY
EAST-NORTHEAST ACROSS THE SOUTH INTERIOR OF WESTERN WASHINGTON. THE
MAIN FRONTAL PRECIPITATION BAND BROUGHT SIGNIFICANT RAIN TO THE
LOWLANDS...AND WE RECEIVED SOME REPORTS OF WET SNOW FALLING TO NEAR
SEA LEVEL ALONG HOOD CANAL. AT 3 AM THE PRECIPITATION BAND HAD MOVED
INTO THE NORTH PART OF THE FORECAST AREA...AND LOWLAND TEMPERATURES
WERE IN THE MID 30S TO MID 40S.
THE WIND HAS BEEN THE REALLY DIFFICULT PART OF THE FORECAST WITH
THIS SYSTEM...DUE TO UNCERTAINTY WITH REGARD TO THE TRACK OF THE
SURFACE LOW. THE 06Z NAM12 MODEL LOOKS TO HAVE THE BEST HANDLE ON
THE LOW RIGHT NOW...SHOWING THAT IT WILL CONTINUE ITS EAST-NORTHEAST
TRACK AND CROSS THE CENTRAL CASCADES BEFORE 10 AM. IT LOOKS
INCREASINGLY LIKELY THAT WINDS MEETING HIGH WIND WARNING CRITERIA --
THAT IS SUSTAINED 40 MPH AND/OR GUSTS 60 MPH -- WILL NOT MATERIALIZE
...DUE PRIMARILY TO THE LOW BEING FURTHER SOUTH THAN PREVIOUSLY
ANTICIPATED. THERE WILL BE WINDY CONDITIONS MAINLY ALONG THE STRAIT
OF JUAN DE FUCA AND ADMIRALTY INLET...AND ALONG THE CENTRAL COAST
AND THROUGH THE LOWER CHEHALIS VALLEY AND SOUTHWEST INTERIOR BEHIND
THE SURFACE LOW. THE HIGH WIND WARNINGS WILL BE DROPPED WITH THE
EARLY MORNING FORECAST PACKAGE.
A WINTER STORM WARNING FOR HEAVY SNOW WILL CONTINUE FOR THE CASCADES
THROUGH 1 PM TODAY...WHILE THE WARNING FOR THE OLYMPICS IS DUE TO
EXPIRE AT 4 AM. THIS LOOKS ON TRACK. ANOTHER 8 TO 16 INCHES OF SNOW
IS LIKELY IN THE CASCADES TODAY...MOST OF IT FALLING THIS MORNING.
ANOTHER 4 TO 8 INCHES IS LIKELY IN THE OLYMPICS.
PRECIPITATION OVER THE WESTERN WASHINGTON LOWLANDS WILL BE SHOWERY
TODAY IN THE WAKE OF THE FRONT...GENERALLY TAPERING OFF DURING THE
AFTERNOON. HOWEVER A PUGET SOUND CONVERGENCE ZONE WILL LIKELY
DEVELOP AND CONTINUE THROUGH THIS EVENING.
A LESS EVENTFUL STRETCH OF WEATHER LOOKS LIKELY BEGINNING TONIGHT
AND CONTINUING THROUGH THE END OF THE WEEK. AN UPPER RIDGE WILL
PROGRESS ACROSS THE FORECAST AREA TONIGHT AND THE NEXT FRONTAL
SYSTEM UPSTREAM -- CURRENTLY OUT ALONG 150W -- WILL APPROACH THE
FORECAST AREA MONDAY. ITS WARM FRONT WILL BRING PRECIPITATION TO THE
OLYMPIC PENINSULA MONDAY MORNING...AND WIDESPREAD PRECIPITATION WILL
SPREAD INLAND LATER MONDAY AND MONDAY NIGHT AS THE COLD FRONT MOVES
THROUGH. A STRONGER RIDGE WILL MOVE OVER WESTERN WASHINGTON TUESDAY
WITH 500 MB HEIGHTS CLIMBING TO AROUND 5700 METERS. MCDONNAL
.LONG TERM...THE UPPER RIDGE MENTIONED ABOVE WILL HEAD EAST OF THE
CASCADES TUESDAY NIGHT...AND ANOTHER WARM FRONT WILL BRUSH THE
NORTHWEST CORNER OF THE AREA AS IT MOVES INTO BRITISH COLUMBIA. THE
TRAILING COLD FRONT WILL DRAG SLOWLY ACROSS THE FORECAST AREA
WEDNESDAY NIGHT THROUGH THURSDAY FOLLOWED BY ITS UPPER TROUGH
THURSDAY NIGHT AND FRIDAY. MCDONNAL
&&
.HYDROLOGY...THE ONLY CURRENT RIVER FLOOD PROBLEM IS THE SKOKOMISH
RIVER. IT IS JUST ABOVE FLOOD STAGE THIS MORNING AND WILL LIKELY
REMAIN ABOVE FLOOD STAGE INTO MONDAY. THIS IS DUE PRIMARILY TO
RELEASES OF WATER FROM CUSHMAN DAM #2. THE SYSTEM MOVING THROUGH
WESTERN WASHINGTON TODAY IS NOT A FLOOD-PRODUCING RAIN SYSTEM BUT
RATHER A HEAVY MOUNTAIN SNOW SYSTEM.
THE FRONTAL SYSTEMS EXPECTED TO ARRIVE DURING THE COMING WEEK WILL
BE ACCOMPANIED BY HIGHER SNOW LEVELS -- PROBABLY IN THE 5000 TO 7000
FT RANGE. ONE FRONT IS FORECAST TO MOVE THROUGH MONDAY AND MONDAY
NIGHT WITH ANOTHER SYSTEM MOVING SLOWLY THROUGH WEDNESDAY NIGHT
THROUGH THURSDAY NIGHT. THEY ARE NOT EXPECTED TO PRODUCE ENOUGH
PRECIPITATION TO CREATE FLOODING CONCERNS.
NO FLOODING IS EXPECTED AT ANY TIME ON THE GREEN RIVER.
&&
.AVIATION...AN UPPER LOW OVER SW WASHINGTON WILL CONTINUE MOVING E.
EXPECT AN UPPER RIDGE TO MOVE OVER THE REGION TONIGHT BEHIND THIS
SYSTEM. ELY FLOW ALOFT WILL BECOME NLY THIS AFTERNOON...AND THEN WLY
OVERNIGHT.
THE STRONG...SFC LOW THAT DEVELOPED OFF THE FAR NORTHERN OREGON
COAST MOVED INLAND...OVER THE MOUTH OF THE COLUMBIA RIVER...ABOUT
10Z. THIS LOW NOW APPEARED TO BE NEAR KKLS AND WAS CONTINUING TO
MOVE E. EXPECT STRONG ONSHORE FLOW TO DEVELOP BY LATE THIS MORNING
IN THE WAKE OF THIS FEATURE. THE STRONGEST WINDS WILL LIKELY OCCUR
OVER THE COAST AND ADMIRALTY INLET AREA. EXPECT THE FLOW TO WEAKEN
OVERNIGHT.
A PUGET SOUND CONVERGENCE ZONE /PSCZ/ WILL DEVELOP N OF THE
SNOHOMISH/KING COUNTY BORDER LATER THIS MORNING AND THEN MOVE S
DURING THE AFTERNOON...BECOMING QUASISTATIONARY OVER THE N CENTRAL
PUGET SOUND. AT THIS TIME...IT LOOKS LIKE THE PSCZ WILL REMAIN N OF
KBFI. WINDS WILL BACK TONIGHT AS THE PRES GRADIENT BECOMES SLY...
THUS EXPECT THE PSCZ TO DRIFT BACK TO THE N AND THEN DISSIPATE LATER
TONIGHT.
CIGS WILL GENERALLY BE IN THE 4-7K FT RANGE TODAY. EXPECT THE LOWER
CLOUD DECK TO BECOME SCATTERED THIS EVENING BUT THERE WILL BE AN
INCREASE IN HIGH LEVEL MOISTURE...ABOVE 15K FT...OVERNIGHT. EXPECT
LOCALIZED FOG...REDUCING VSBYS INTO 3-5SM...TO DEVELOP LATER
TONIGHT...BUT MAINLY IN THE FAVORED RIVER VALLEYS.
KSEA...ELY WINDS WILL DROP OFF BY MIDMORNING AND THEN KICK UP FROM
THE SW LATER THIS MORNING. CIGS WILL MAINLY BE IN THE 5-6K FT
RANGE...ALTHOUGH THE CLOUDS WILL BECOME SCATTERED LATER TODAY...IF
NOT EARLIER.
&&
.MARINE...STRONG WESTERLY FLOW WILL DEVELOP IN THE WAKE OF A 985 MB
LOW THAT MOVED INLAND EARLIER. THIS WILL RESULT IN GALE FORCE
WESTERLY WINDS OVER MUCH OF THE AREA...WITH A BRIEF PERIOD OF STORM
FORCE WINDS POSSIBLE OVER THE CENTRAL STRAIT OF JUAN DE FUCA THIS
MORNING. THE ONSHORE FLOW WILL WEAKEN TONIGHT. ANOTHER...BUT
WEAKER...FRONTAL SYSTEM WILL AFFECT THE AREA ON MON. EXPECT OFFSHORE
