AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
910 AM PST MON MAR 5 2012

.SYNOPSIS...A COLD FRONT WILL MOVE THROUGH WESTERN WASHINGTON THIS
MORNING. A COLD UPPER LEVEL TROUGH WILL MOVE OVER THE AREA TONIGHT
WITH THE SNOW LEVEL FALLING BELOW 500 FEET. HIGH PRESSURE WILL BE
OVER THE PACIFIC NORTHWEST TUESDAY THROUGH THURSDAY. A FRONT WILL
ARRIVE LATE IN THE WEEK WITH A STRONGER FRONTAL SYSTEM POSSIBLE LATE
NEXT WEEKEND.

&&

.SHORT TERM...STEADY RAIN THROUGH THE INTERIOR THIS MORNING WILL
CHANGE OVER TO SCATTERED SHOWERS AS A COLD FRONT PASSES THROUGH. THE
FRONT JUST PUSHED THROUGH THE COAST WHICH MATCHES THE LATEST
GUIDANCE. THE SNOW LEVEL IS AROUND 3000 FT BUT WILL CONTINUE TO FALL
AS COLDER AIR MOVES INLAND. EXPECT HEAVY SNOW IN THE
MOUNTAINS...ESPECIALLY THE WEST SLOPES OF THE CASCADES WHERE A
WINTER STORM WARNING REMAINS IN EFFECT.

THE AIR MASS WILL REMAIN COOL AND UNSTABLE TONIGHT AS AN UPPER LEVEL
TROUGH CROSSES WESTERN WA. THE INFRARED SHOWS CONVECTIVE CU JUST OFF
HAIDA GWAII TRACKING S/SW. THESE CELLS MAY CLIP THE COAST TONIGHT
OTHERWISE THE CHANCE OF SEEING T-STORMS LOOKS LOW FOR THE INTERIOR.
WILL PROBABLY DROP THE MENTION OF THUNDERSTORMS IN THE FORECAST
- WHICH MATCHES THE SPC CONVECTIVE OUTLOOK. SHOWERS WILL TAPER DOWN
TONIGHT /MAINLY AFTER MIDNIGHT/ AS THE UPPER LEVEL TROUGH DIGS SOUTH
AND EAST OF THE AREA. THE AIR MASS IS COOL ENOUGH TO SEE LOWLAND
SNOW /SNOW LEVELS ONLY A FEW HUNDRED FEET OFF THE SURFACE/ BUT MODEL
QPF LOOKS RATHER LIGHT...OUTSIDE OF A PUGET SOUND CONVERGENCE ZONE.
MAY SEE A RAIN/SNOW MIX WITHIN THE PSCZ BUT SNOWFALL ACCUMULATIONS
LOOK LOW.

THE AIR MASS WILL DRY OUT TUE AFTERNOON THROUGH WED AS AN UPPER
LEVEL RIDGE BUILDS INLAND. NW FLOW WILL KEEP THE TEMPS ON THE COOL
SIDE BUT WE SHOULD SEE PLENTY OF SUNSHINE BOTH DAYS. 33

.LONG TERM...PREVIOUS DISCUSSION...AN UPPER RIDGE SHIFTS OVER THE
PACNW THROUGH THE MIDDLE OF THE WEEK...500MB HEIGHTS OVER WRN WA
PEAK JUST ABV 570DAM 18Z THU. THE FCST HAS A LOT OF SUNSHINE IN IT
AND THAT LOOKS FINE. LATE IN THE WEEK AN UPPER SHORTWAVE AND FRONT
REACH THE AREA...BUT THE FRONT MAY NOT HAVE A GREAT DEAL OF PUNCH TO
IT...THE HEIGHT FALLS STRETCH OUT THROUGH FRIDAY AND ANOTHER SYSTEM
LATE IN THE WEEKEND LOOKS STRONGER AND MORE INTERESTING. THAT SYSTEM
IS NOT REALLY IN THE FCST YET. 19

&&

.HYDROLOGY...FLOODING IS UNLIKELY OVER THE NEXT 7 DAYS.

&&

.AVIATION...STRONG WSW FLOW ALOFT WILL CONTINUE OVER W WA THROUGH
00Z. A COLD FRONT NEAR THE COAST AT 16Z WILL CROSS THE GREATER PUGET
SOUND REGION AROUND 18Z THE WEAKEN OVER THE CASCADES THROUGH 00Z.
THE AIR MASS IS MOIST AND STABLE AHEAD OF THE COLD FRONT...AND WILL
REMAIN MOIST AND BECOME UNSTABLE BEHIND THE COLD FRONT AS AN UPPER
LEVEL TROUGH APPROACHES W WA. THE UPPER LEVEL TROUGH WILL MOVE OVER
W WA BY 06Z. A PUGET SOUND CONVERGENCE ZONE WILL FORM BEHIND THE
FRONT AND PERSIST THROUGH TONIGHT...AND WITH THE EVOLVING ONSHORE
AND UPPER LEVEL FLOW IT WILL PROBABLY MOVE AROUND A BIT.

MVFR CIGS 010-030 ARE WIDESPREAD ACROSS W WA AT 16Z WITH LOCAL
VISIBILITIES 3-5SM -RA. RADAR SHOWS THE COLD FRONT POISED TO MOVE
ACROSS PUGET SOUND AT 16Z AND SHOULD BE OVER THE CASCADES BY 19Z.
MAY SEE A COUPLE OF HOURS OF SPOTTY IFR CIGS IMMEDIATELY BEHIND THE
FRONT...BUT THEN CIGS SHOULD LIFT TO A MIX OF VFR 030-050 WITH LOCAL
MVFR CIGS 020-030.

KSEA...SW WIND 15-25 KT THROUGH 00Z. CIGS WILL REMAIN OVC010-020
WITH VIS 3-5SM THROUGH 18Z AHEAD OF THE COLD FRONT. THERE IS A
CHANCE OF BRIEF CIGS DOWN TO BKN008 18Z-20Z...BUT NOT CERTAIN. CIGS
WILL BE BKN025-050 AFTER 20Z.

A COLDER AIR MASS WILL ARRIVE BEHIND THE COLD FRONT...WITH THE SNOW
LEVEL FALLING TO AROUND 1000 FT THIS AFTERNOON AND 500 FT THIS
EVENING AND TO NEAR THE SURFACE LATE TONIGHT. THE KEY FOR SNOW WILL
BE PRECIPITATION...AND JUST ABOUT ALL THE SHOWER ACTIVITY WILL BE
RELATED TO THE CONVERGENCE ZONE. THE CONVERGENCE ZONE SHOULD MOVE
DOWN OVER SEATTLE THIS EVENING...BUT IT IS POSSIBLE THAT SOME SNOW
SHOWERS COULD REACH KSEA. ANY ACCUMULATIONS ARE EXPECTED TO BE LESS
THAN AN INCH. KAM

&&

.MARINE...OBS SHOW ONSHORE FLOW IS INCREASING BEHIND THE COLD FRONT
AS EXPECTED. THE FRONT CROSSED THE COAST AROUND 16Z AND WILL TRANSIT
PUGET SOUND AROUND 18Z. GALES FORECAST FOR THE CENTRAL/EAST STRAIT
LOOK GOOD...AS DO THE SCA FOR ALL OTHER WATERS. ONSHORE FLOW WILL
WEAKEN TONIGHT/TUESDAY AS AN OFFSHORE SURFACE RIDGE BUILDS INLAND.
THE RIDGE WILL SETTLE OVER THE AREA WEDNESDAY/THURSDAY FOR A PERIOD
OF WEAKER WINDS. KAM

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...WINTER STORM WARNING CASCADES.
     WINTER WEATHER ADVISORY OLYMPICS.

PZ...GALE WARNING CENTRAL AND EAST STRAIT OF JUAN DE FUCA.
