Area forecast discussion, Feb 18, 3:00 AM PST, 5 hours 47 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 AM PST SAT FEB 18 2012
.SYNOPSIS...A VIGOROUS UPPER TROUGH WILL BRING COOL SHOWERY WEATHER
TO WESTERN WASHINGTON TODAY...WITH A CHANCE OF THUNDERSTORMS COAST
AND SOUTH PART. HEAVY SNOW WILL FALL IN THE MOUNTAINS AS THE SNOW
LEVEL DROPS TO 2000 FEET. A RELATIVE BREAK IN THE WEATHER IS LIKELY
SUNDAY...WITH A WET AND MILD PATTERN DEVELOPING NEXT WEEK.
&&
.SHORT TERM...A DEEP VERTICALLY STACKED LOW IS NEAR THE WEST SIDE OF
VANCOUVER ISLAND EARLY THIS MORNING...WITH DIFFLUENT SOUTHWEST FLOW
ALOFT OVER WESTERN WASHINGTON. WIDESPREAD SHOWERS COVER THE FORECAST
AREA...AND THE SNOW LEVEL HAS FALLEN TO AROUND 2500 FT. THE
SOUTHEAST SURFACE PRESSURE GRADIENT HAS BEEN GRADUALLY INCREASING...
WITH BREEZY TO WINDY CONDITIONS. TEMPERATURES AT 3 AM WERE IN THE
UPPER 30S TO MID 40S.
THE CLOSED LOW WILL WEAKEN INTO AN OPEN UPPER TROUGH TODAY AS IT
MOVES INTO THE NORTH CASCADES. THE SURFACE TROUGH...OR MAYBE EVEN A
BENT-BACK OCCLUSION...WILL MOVE ACROSS THE FORECAST AREA AT THE SAME
TIME. THIS VIGOROUS FEATURE WILL PRODUCE WIDESPREAD SHOWERS ACROSS
WESTERN WASHINGTON TODAY. ISOLATED THUNDERSTORMS HAVE DEVELOPED
ALONG THE NORTH OREGON COAST IN THE LAST COUPLE HOURS...AND I WILL
KEEP A CHANCE IN THE FORECAST FOR OUR COAST AND THE SOUTHWEST
INTERIOR. THE SYSTEM WILL MOVE INTO EASTERN WASHINGTON THIS
EVENING...WITH NORTHWEST FLOW ALOFT DEVELOPING OVER WESTERN
WASHINGTON TONIGHT. SHOWERS AND WINDS WILL GRADUALLY TAPER OFF.
FAIRLY STRONG LOW LEVEL WESTERLY FLOW WILL ENHANCE PRECIPITATION IN
THE MOUNTAINS...ESPECIALLY THE CASCADES...AS THE SNOW LEVEL FALLS TO
AROUND 1500 FT. HEAVY SNOW AMOUNTS HAVE ALREADY FALLEN AT MOUNT
BAKER...AND THE WINTER STORM WARNING SHOULD VERIFY EASILY AT
PARADISE AS THE HEAVIER PRECIPITATION GENERALLY SHIFTS SOMEWHAT
SOUTH.
THE SOUTHEAST PRESSURE GRADIENT SHOULD REACH ITS PEAK MIDDAY
TODAY...AND WINDS SHOULD BE WELL INTO THE ADVISORY RANGE FOR THE
COAST AND NORTH INTERIOR BUT MOST LIKELY REMAIN BELOW WARNING
CRITERIA.
SUNDAY WILL BE A RELATIVE BREAK IN THE WEATHER...WITH A FLAT UPPER
RIDGE OFFSHORE AND NORTHWEST FLOW ALOFT OVER WESTERN WASHINGTON.
LIGHT SHOWERS ARE POSSIBLE...BUT THE INTERIOR LOWLANDS AT LEAST
SHOULD SEE A LITTLE SUNSHINE.
A FRONTAL SYSTEM WILL MOVE THROUGH THE UPPER RIDGE INTO THE PACIFIC
NORTHWEST SUNDAY NIGHT OR MONDAY. THE MODELS DO NOT HAVE THE DETAILS
OF THIS SYSTEM WELL PINNED DOWN. IN FACT THE SYSTEM WAS ESSENTIALLY
NON-EXISTENT IN SOME MODEL RUNS AS RECENTLY AS EARLY FRIDAY MORNING.
AT ANY RATE...THIS FIRST SYSTEM THAT MOVES THROUGH THE DIRTY RIDGE
WILL NOT HAVE GREAT IMPACT WITH ITS CORE PROBABLY MOVING INLAND JUST
TO THE SOUTH OF OUR FORECAST AREA. MCDONNAL
.LONG TERM...THE NEXT FRONTAL SYSTEM WILL MOVE THROUGH THE DIRTY
RIDGE AND BRING ANOTHER ROUND OF PRECIPITATION TO THE FORECAST AREA
LATE MONDAY NIGHT INTO WEDNESDAY. PRECIPITATION WILL BE MORE
SIGNIFICANT...AND THE SNOW LEVEL WILL RISE TO AROUND 6000 FT. MODELS
ARE STILL SOMEWHAT INCONSISTENT WITH REGARD TO HOW HEAVY THE RAIN
WILL BE. THURSDAY SHOULD BE ANOTHER RELATIVE BREAK IN THE WEATHER...
BEFORE A FRONTAL SYSTEM ASSOCIATED WITH A FAIRLY DEEP UPPER LOW
ARRIVES FRIDAY. MCDONNAL
&&
.HYDROLOGY...THE SYSTEM MOVING THROUGH THE FORECAST AREA TODAY AND
TONIGHT SHOULD NOT HAVE MUCH IMPACT ON THE RIVERS. THE SKOKOMISH IS
RISING A BIT...BUT EVEN IT SHOULD REMAIN BELOW ITS ADVISORY STAGE.
A WARMER AND WET PATTERN WILL DEVELOP EARLY NEXT WEEK. A FRONTAL
SYSTEM WILL MOVE THROUGH THE RIDGE OFFSHORE AND BRING PRECIPITATION
TO WESTERN WASHINGTON LATE MONDAY NIGHT THROUGH WEDNESDAY...WITH THE
SNOW LEVEL CLIMBING TO AROUND 6000 FT. RUNS OF THE GFS AND EUROPEAN
MODEL SINCE 12Z FEB 17 HAVE BACKED OFF SOMEWHAT FROM THE HEAVIER
PRECIPITATION AMOUNTS SHOWN IN SOME EARLIER MODEL RUNS. THE RECENT
RUNS SHOW UP TO 3 INCHES OF RAIN ALONG THE WEST SLOPES OF THE
CASCADES DURING A 48-HOUR PERIOD...WHICH WOULD NOT BE ENOUGH TO
PRODUCE FLOODING. WE STILL CANNOT RULE OUT ANY FLOODING ENTIRELY...
BUT WE CAN SAY IT LOOKS UNLIKELY. MCDONNAL
&&
.AVIATION...AN UPPER LEVEL AND 998 MB SURFACE LOW OVER NORTHERN
VANCOUVER ISLAND AT 09Z WILL MOVE SE OVER SOUTHERN VANCOUVER ISLAND
BY 20Z...WHILE THE SURFACE LOW FILLS TO 1008 MB. THE SYSTEM WILL
CONTINUE WEAKENING 20Z-06Z AS IT MOVES OVER EASTERN WA. A MOIST
SHOWERY UNSTABLE AIR MASS WILL REMAIN OVER W WA THROUGH THIS EVENING
WITH A DIMINISHING TREND TONIGHT. LATEST SATELLITE AND RADAR IMAGERY
AT 1030Z SHOW NUMEROUS SHOWERS CURRENTLY OVER W WA AS WELL AS
OFFSHORE HEADED TOWARD THE COAST.
CIGS WILL VARY WIDELY FROM VFR IN SPOTS WHERE THERE HAVE BEEN LONGER
LULLS IN SHOWER ACTIVITY...TO PREDOMINANTLY MVFR AND LOCAL BRIEF IFR
CONDITIONS WHERE SHOWERS ARE FREQUENT. LOCAL MVFR AND POSSIBLY BRIEF
IFR VISIBILITY MAY DEVELOP AROUND HEAVIER SHOWERS. STRONG S-SW
PRESSURE GRADIENTS WILL MAINTAIN GUSTY SURFACE WINDS. DUE TO THE
FREQUENT VARIATIONS IN CONDITIONS AS SHOWERS CROSS THE
TERMINALS...THE TAFS WILL BE AIMED MORE TOWARD PREDOMINANT
CONDITIONS.
.KSEA...SHOWERS WILL CONTINUE MOVING ACROSS KSEA TODAY...WITH CIGS
MAINLY BKN-OVC010-030...BUT VARYING FREQUENTLY. VISIBILITY WILL BE
PREDOMINANTLY P6SM BUT MAY DROP TO MVFR IN HEAVIER SHOWERS. S-SW
SURFACE WINDS WILL CONTINUE 10-20 KT GUSTING TO AROUND 30 KT AT
TIMES. WSW WINDS ALOFT FROM FL050-FL100 WILL VARY FROM 35-50 KT
12Z-21Z. KAM
&&
.MARINE...A STRONG 998 MB LOW OVER NORTHERN VANCOUVER ISLAND AT 09Z
WILL MOVE SLOWLY SE OVER SOUTHERN VANCOUVER ISLAND BY MIDDAY
TODAY...WHILE FILLING TO AROUND 1008 MB. THE LOW WILL OPEN UP INTO A
SURFACE TROUGH THIS AFTERNOON AS IT CROSSES THE CASCADES...REACHING
THE ID PANHANDLE BY EARLY THIS EVENING.
A SURFACE RIDGE WILL BEGIN BUILDING INLAND IMMEDIATELY BEHIND THE
LOW...WITH PRESSURE GRADIENTS GRADUALLY WEAKENING THROUGH SUNDAY
MORNING...UNTIL THE RIDGE SETTLES BRIEFLY AS A SURFACE HIGH OVER W
WA MIDDAY SUNDAY. STRONG PRESSURE GRADIENTS ASSOCIATED WITH THE LOW
WILL PRODUCE PERIODS OF GALE FORCE WINDS IN MOST AREAS. GALE FORCE
WESTERLIES IN THE STRAIT WILL DEVELOP THIS AFTERNOON BEHIND THE LOW.
IN ADDITION THE LOW HAS GENERATED A LARGE W SWELL TRAIN FROM 23-28
FT THAT REACHED THE COAST AFTER MIDNIGHT AND WILL WILL CONTINUE
THROUGH THIS EVENING. KAM
&&
.SEW WATCHES/WARNINGS/ADVISORIES...
WA...HIGH SURF WARNING THROUGH THIS EVENING ALONG THE COAST.
WINTER STORM WARNING CASCADES THROUGH SUNDAY MORNING.
WINTER WEATHER ADVISORY OLYMPICS THROUGH TODAY.
