AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SEATTLE WA
230 PM PST FRI NOV 30 2007

.SYNOPSIS...WITH COLD AIR IN PLACE OVER WESTERN WASHINGTON...THE
NEXT WEATHER SYSTEM WILL LIKELY BRING SNOW. A FEW INCHES ARE LIKELY
SATURDAY AFTERNOON AND EVENING. THE MOUNTAINS WILL RECEIVE HEAVY
SNOW. SNOW WILL CHANGE TO RAIN OVER THE LOWLANDS SATURDAY NIGHT AND
RAIN WILL CONTINUE SUNDAY AND MONDAY...WITH FLOODING POSSIBLE. THE
REST OF NEXT WEEK WILL BE SHOWERY.

&&

.SHORT TERM...THIS IS SHAPING UP AS A WEATHER-FILLED WEEKEND.
PROBLEMS WITH SNOW IN THE LOWLANDS...HEAVY SNOW IN THE MOUNTAINS...
WIND...AND HEAVY RAIN LEADING TO POSSIBLE FLOODING ARE ALL ON THE
MENU.

SNOW IN THE LOWLANDS. COLD AIR IS IN PLACE AND AT LEAST A LITTLE
SNOW SEEMS LIKELY TOMORROW AS A WEAK SYSTEM BRINGS SOME PCPN. HAVE
GONE FOR ADVISORY AMOUNTS IN THE LOWLANDS...MAINLY 1 OR 2 INCHES BUT
SOME ZEROES AND 3-INCH AMOUNTS AS WELL. THE STORM IS NOT STRONG AND
GFS AMOUNTS ARE ON THE ORDER OF A COUPLE OF TENTHS OF AN INCH OF
MOISTURE. WARMING TREND BEGINS IN THE EVENING WITH SOUTHERLY WINDS
AND 850MB TEMPS RISING FROM MINUS 8 TO MINUS 4 OR WARMER...WHICH
SHOULD EFFECTIVELY TURN SNOW TO RAIN. TEMPS LIKELY TO BE IN THE 30S
ALL DAY AND THIS WILL PROBABLY MEAN HILLS AND INLAND AREAS GET SOME
SNOW...PLACES NEAR PUGET SOUND GET LESS OR GO WITHOUT. BUT SNOW IS
POSSIBLE ALL LOWLAND AREAS. EXPECTING PCPN TO BEGIN BY NOON MOST
AREAS WHICH IS MORE THAN 12 HOURS AWAY...WILL HANDLE THE POSSIBILITY
IN A SPECIAL WEATHER STATEMENT RATHER THAN A SNOW ADVISORY. SOME
OUTLIERS...WINDS SHOULD BE EASTERLY AND DOWNSLOPE IN THE EAST PUGET
SOUND LOWLANDS AND MUCH OF THAT AREA MIGHT NOT GET ANY SNOW. THE
SAME COULD BE SAID OF THE SEATTLE METRO AREA. ON THE OTHER
HAND...KITSAP PENINSULA AND HOOD CANAL AREA WILL PROBABLY GET A BIT
MORE SNOW. FINALLY...THE FAR NW INTERIOR WILL NOT GET THE WARMUP
FROM SOUTHERLY WINDS UNTIL AFTER MIDNIGHT...COULD KEEP SNOWING AND
ACCUMULATING SEVERAL HOURS LONGER THERE.

HEAVY SNOW IN THE MOUNTAINS. SNOW WILL FALL IN THE MOUNTAINS
SATURDAY AFTERNOON AND NIGHT. SNOW LEVEL QUITE LOW...ESSENTIALLY
ZERO. WILL ALSO BE WINDY AT TIMES...GIVING VISIBILITY RESTRICTIONS.
SO WINTER STORM WARNING WILL BE ISSUED THIS AFTERNOON TO COVER THE
PERIOD FROM SATURDAY MORNING THROUGH SUNDAY MORNING FOR BOTH THE
CASCADES AND OLYMPICS. AMOUNTS WITH THIS FIRST STORM WILL BE
MARGINALLY STORMY. HOWEVER...SNOW WILL CONTINUE IN THE CASCADES
SUNDAY INTO MONDAY MORNING...AND THESE AMOUNTS WILL BE HEAVY. LIKELY
TO GET 2-3 FEET IN THE PASSES BY MONDAY MORNING. RATHER THAN MESS
AROUND WITH A SNOW ADVISORY OR A WINTER STORM WATCH...WILL GO
STRAIGHT TO A WARNING. AVALANCHE CENTER HAS ISSUED AN AVALANCHE
WATCH WHICH DOVETAILS NICELY WITH THIS IDEA.

WIND. SOME WIND ON SUNDAY WITH SECOND SYSTEM. THIS ONE LOOKS LIKE A
GALE OVER MOST WATERS WITH WIND APPROACHING BUT PROBABLY NOT
REACHING MARGINAL HIGH WIND CRITERIA ON THE COAST. NOT TOO EXCITED
ABOUT IT AT THIS POINT. MONDAY STORM...THE THIRD IN THE SERIES FOR
THOSE KEEPING COUNT...IS STRONGER AND COULD BE A MARGINAL HIGH WIND
PRODUCER ON THE COAST AND OVER THE NW INTERIOR. THIS COULD MEAN LOW
END STORM FORCE WINDS IN THOSE LOCATIONS. WILL MONITOR...STILL 72
HOURS AWAY.

POSSIBLE FLOODING. RAIN AMOUNTS ON SUNDAY OVER THE OLYMPICS ARE
PRETTY GOOD...A FEW INCHES...BUT ON MONDAY THEY ARE QUITE
IMPRESSIVE. ADDING THE GFS RAINFALL OVER THE 24 HOURS OF MONDAY IN
THE OLYMPICS GIVES OVER 7 INCHES. AND ON MONDAY THE CASCADES WILL BE
RAINING AS WELL AS SW FLOW BRINGS A FAST WARMUP...RAISING THE SNOW
LEVEL FROM BASICALLY ZERO TO 6000 FEET OR HIGHER. THE UPSHOT IS A
POTENTIAL FOR FLOODING FROM THE MONDAY RAINS. WILL ISSUE A FLOOD
POTENTIAL OUTLOOK THIS AFTERNOON. BURKE

.LONG TERM...NOT TOO CONCERNED WITH THE LONG TERM. PATTERN LOOKS
SHOWERY OR WITH WEAK IMPULSES BRINGING RAIN AT TIMES. SNOW LEVEL
STARTS HIGH AND FALLS SOME DURING THE WEEK. BURKE

&&

.AVIATION...DELAYED.

&&

.MARINE...DELAYED.
