The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Seattle, WA wrote its last area forecast discussion before this river flood warning went out at Mar 30, 3:00 AM PDT, 5 hours 58 minutes earlier.
Area forecast discussion, Mar 30, 3:00 AM PDT, 5 hours 58 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 AM PDT WED MAR 30 2011
.SYNOPSIS...A PLUME OF SUBTROPICAL MOISTURE WILL BRING RAIN TO
WESTERN WASHINGTON THROUGH THURSDAY. THE RAIN MAY BE HEAVY AT TIMES
AT THE COAST AND IN THE MOUNTAINS. DRIER WEATHER IS EXPECTED FRIDAY
AS HIGH PRESSURE BUILDS OVER THE AREA. AN UPPER TROUGH WILL BRING
MORE SHOWERS TO WESTERN WASHINGTON THIS WEEKEND.
&&
.SHORT TERM...THE LATEST PACIFIC SATELLITE IMAGERY IS QUITE
IMPRESSIVE SHOWING A VERY LONG FETCH OF HIGH MOISTURE LATENT AIR
STREAMING INTO WRN WA EARLY THIS MORNING. THIS FIRST ROUND OF HEAVY
COASTAL/MOUNTAIN RAINFALL IS OCCURING WITH THE WARM FRONT LIFTING
ACROSS THE AREA CAUSING FREEZING LEVELS TO RISE TO OVER 8K FT AS
EVIDENT ON BOTH THE WESTPORT AND RAVENSDALE PROFILIERS. WITH
SATELLITE IMAGERY SHOWING THE MOISTURE FETCH REACHING ALL THE WAY
OUT TO THE WRN TROPICAL PACIFIC...THE 36-48 HOURS OF HEAVY MOUNTAIN
RAINFALL ADVERTISED BY ALL MODELS SEEMS LIKELY. EXACTLY WHERE THIS
MOISTURE FETCH ENDS UP FOCUSING AND FOR HOW LONG WILL DETERMINE
PRECIP AMOUNTS AND WHICH RIVER BASINS MIGHT EXPERIENCE FLOODING. SEE
THE LATEST HYDRO DISCUSSION BELOW FOR FURTHER DETAILS.
MANY LOWLAND AREAS WILL SEE SOME PERIODS OF HEAVY RAINFALL AS
WELL...ESPECIALLY ALONG THE COAST AND SW INTERIOR. THE H850 WLY FLOW
WILL LIKELY SHADOW THE CENTRAL AND N PORTIONS OF THE PUGET SOUND
REGION WITH RAINFALL BECOMING HEAVIER HEADING E TOWARD THE
FOOTHILLS. WILL WORD THE ZONE FORECAST TO MENTION ONLY OCCASIONAL
RAIN FOR THE SEATTLE-BREMERTON-EVERETT VICINITY ZONES.
MODELS GENERALLY AGREE THAT THE HEAVY MOUNTAIN RAINFALL WILL BEGIN
TO TAPER OFF BY THURSDAY AFTERNOON AS THE DEEP MOISTURE TAP BECOMES
CUT OFF DUE TO A SHARPENING OF THE TROUGH OFFSHORE. RAIN WILL BECOME
LIGHTER AND SHOWERY OVER THE LOWLANDS THURSDAY NIGHT.
.LONG TERM...LONG RANGE MODELS SHOW A CHANGE IN THE PATTERN OVER THE
WEEKEND INTO THE MIDDLE OF NEXT WEEK. A SERIES OF COOLER UPPER
TROUGHS WILL DIG SWD OUT OF THE GULF OF AK ACROSS THE PAC NW. THESE
SYSTEM WILL BRING SHOWERY WEATHER TO THE LOWLANDS AND PERIODS OF
SNOW TO THE MOUNTAINS WILL SNOW LEVELS FALLING BACK DOWN TO THE 3-4K
FT LEVEL. SOME MODEL SUGGEST A PERIOD OF MOSTLY DRY WEATHER SUNDAY
INTO EARLY MONDAY BUT CONFIDENCE ON TIMING OF ANY BREAKS THAT FAR
OUT IS LOW. WILL KEEP A CHANCE OF SHOWERS IN THE FORECAST. MERCER
&&
.HYDROLOGY...NOT MUCH CHANGE IN THE 00Z MODEL RUNS WITH THE NAM AND
THE GFS CONTINUING TO SHOW DIFFERENCES IN THEIR SOLUTIONS. THE NAM
SHOWS THE HEAVIEST PRECIPITATION OVER THE CENTRAL AND SOUTHERN
CASCADES FROM ABOUT STEVENS PASS TO MOUNT ST HELENS AND TO A LESSER
EXTENT OVER THE OLYMPICS. THE GFS SOLUTION SHOWS THE HEAVIEST
PRECIPITATION FROM ABOUT SNOQUALMIE PASS NORTHWARD. THESE
DIFFERENCES HAVE IMPORTANT CONSEQUENCES FOR THE RIVERS. BOTH OF THE
MODELS SHOW THE PRECIPITATION TAPERING OFF QUICKLY 18Z THURSDAY TO
00Z FRIDAY. CURRENT OBSERVATIONS SHOW THE HEAVIEST PRECIPITATION
OVER THE CENTRAL AND SOUTHERN CASCADES WITH PARADISE GETTING 0.95
INCHES IN THE LAST 5 HOURS. WESTPORT PROFILER SHOWS IN INCREASE IN
THE WINDS AT 850 MB UP TO NEAR 40 KNOTS OUT OF THE WEST SOUTHWEST
WITH A QUICK JUMP IN THE FREEZING LEVEL LAST NIGHT FROM NEAR 4000
FEET UP TO AROUND 7500 FEET. TPW VALUES OFF THE COAST IN THE 1 TO
1.5 INCH RANGE EXTENDING WELL BACK INTO THE CENTRAL PACIFIC.
SATELLITE IMAGERY RIGHT NOW DOES NOT SHOW MUCH IN THE WAY OF RIDGING
OFFSHORE THAT WOULD HELP PUSH THE PRECIPITATION NORTHWARD. THIS
COMBINED WITH THE ALMOST WESTERLY WINDS AT 850 MB ON THE WESTPORT
PROFILER WILL LEAN THE QPF IN THE NEXT 24 HOURS TOWARD THE NAM
SOLUTION WITH THE HIGHEST AMOUNTS IN THE CENTRAL CASCADES.
WITH THE FOCUS OF THE PRECIPITATION IN THE CENTRAL CASCADES
THE SNOHOMISH-SNOQUALMIE RIVER SYSTEM...INCLUDING THE SKYKOMISH AND
TOLT...ALONG WITH THE STILLAGUAMISH RIVER...ARE AT THE HIGHEST RISK
OF FLOODING. CURRENT MODEL GUIDANCE HAS THE FIRST RIVER TO GO ABOVE
FLOOD STAGE IN THIS GROUP...THE SNOQUALMIE AT THE FALLS...REACHING
FLOOD STAGE LATE THIS AFTERNOON WITH OTHER RIVERS REACHING FLOOD
STAGE TONIGHT OR THURSDAY MORNING. EVEN WITH THE RIVERS TRACKING
THEIR HYDROGRAPHS WELL EARLY THIS MORNING...ALL OF THE RIVERS ARE
WELL BELOW FLOOD STAGE. WITH THE UNCERTAINTY IN THE SITUATION FOR
NOW WILL STAY WITH THE FLOOD WATCH EARLY THIS MORNING.
RIVERS FLOWING OFF THE OLYMPICS ALSO COULD FLOOD. EXPERIENCE SHOWS
THE SKOKOMISH NEARLY ALWAYS FLOODS IN THESE SCENARIOS...AND A FEW
OTHER RIVERS COULD ALSO FLIRT WITH FLOOD STAGE. THE 00Z NAM SHOWS AN
INCREASE OVER PREVIOUS FORECASTS IN THE PRECIPITATION AMOUNTS OVER
THE WILLAPA HILLS BUT THE HEAVIEST PRECIPITATION ONLY LASTS FOR 12
HOURS BEFORE TAPERING OFF. THIS SCENARIO WILL LEAVE THE CHEHALIS
RIVER OUT OF THE MOST LIKELY TO FLOOD CATEGORY.
USED A BLEND OF THE MM5-NAM AND MM5-GFS TO ARRIVE AT THE QPF GRIDS.
WHILE THE STORM TOTAL AMOUNTS REMAIN SIMILAR TO THE PREVIOUS
FORECASTS HAVE INCREASED THE PRECIPITATION IN THE SNOQUALMIE PASS TO
MOUNT RAINIER AREA FOR THE 06Z WEDNESDAY TO 00Z THURSDAY TIME FRAME
BY ANOTHER QUARTER TO HALF AN INCH. STORM TOTALS REMAIN IN THE 4-6
INCH RANGE FOR THE CENTRAL CASCADES DURING THE PERIOD 00Z WEDNESDAY
THROUGH 00Z FRIDAY...WITH A FEW SPOTS NEAR 7 INCHES. NORTH AND SOUTH
OF THE CENTRAL CASCADES AMOUNTS ARE MORE LIKE 2-4 INCHES WITH SOME 5
INCH BULLSEYES. THE OLYMPICS HAVE 3-5 INCHES.
RAINFALL OVER THE GREEN RIVER BASIN WILL BE HEAVY AT TIMES...PERHAPS
EXCEEDING 3 INCHES OVER 48 HOURS. LOCAL INFLOW BELOW HOWARD HANSON
DAM COULD BE SIGNIFICANT. FELTON/BURKE
&&
.AVIATION...STRONG MOIST NW FLOW ALOFT WILL CONTINUE OVER W WA
THROUGH TONIGHT...PRODUCING PERIODS OF RAIN AND CIGS BELOW
BKN-OVC030. AREAS OF IFR OR LOW MVFR CIGS WILL BE COMMON WITH LOCAL
VISIBILITY 3-5SM -RA BR. STRONG LOWER LEVEL W FLOW ACROSS THE
OLYMPICS ON WEDNESDAY SHOULD PRODUCE A PARTIAL RAIN SHADOW OVER
CENTRAL PUGET SOUND WITH SLIGHTLY HIGHER CIGS POSSIBLE AT TIMES. THE
AIR MASS IS STABLE.
KSEA...RAINY PATTERN WILL CONTINUE THROUGH TONIGHT. CIGS HAVE TANKED
AND ARE NOW HANGING AROUND BKN-OVC010 EVEN THOUGH RADAR SHOWS THE
OLYMPIC RAIN SHADOW HAS ALREADY SET UP OVER PUGET SOUND. COULD STILL
SEE CIGS POP UP BRIEFLY TO ABOVE OVC020...BUT NO WAY TO REALLY
FORECAST THAT WITH ANY SKILL...SO WILL THROW IN THE WET SQUISHY
TOWEL AND JUST KEEP CIGS BELOW OVC020. S WINDS HAVE RISEN TO AROUND
15 KT AND SHOULD STAY IN THE SUSTAINED 10-20 RANGE THROUGH THIS
AFTERNOON. NO WIND SHIFTS EXPECTED. KAM
&&
.MARINE...S PRESSURE GRADIENTS HAVE COME UP AND WINDS HAVE REACHED
SCA LEVELS IN PUGET SOUND. GRADIENT HAS GONE W IN THE STRAIT AND
RACE ROCKS IS ALREADY AT 15 KT. WITH MODERATE SW ONSHORE FLOW
TODAY...WILL KEEP ADVISORIES GOING INTO THIS EVENING OR LATER FOR
ALL AREAS EXCEPT CENTRAL/EAST STRAIT. GALE WARNING IS UP FOR THAT
AREA. MESOSCALE MODELS ARE STILL ON THE WEAK SIDE WITH THE WINDS IN
THE STRAIT...ALTHOUGH THE WRF-GFS CAUGHT THE EARLY SHIFT TO
WESTERLIES WHERE THE NAM DID NOT. GFS/NAM BOTH SHOW 3 PLUS MB
UIL-BLI GRADIENT THROUGH THE STRAIT FROM 18Z ON WHICH IS ENOUGH FOR
A BORDERLINE GALE WARNING. LOWER LEVEL WINDS ARE ALSO MODERATE TO
STRONG WESTERLIES WHICH SUPPORTS THE GALE.
00Z GFS SHOWS EVEN STRONGER WESTERLY PRESSURE GRADIENTS THURSDAY
AFTER A SHORTWAVE TROUGH CROSSES THE AREA. HAVE KEPT THE WINDS AT
HIGH END SCA FOR NOW...BUT GALES WILL BE CONSIDERED IF THE 06Z/12Z
RUNS STICK WITH THIS SOLUTION. EXPECT WESTERLY ONSHORE FLOW TO
WEAKEN THURSDAY NIGHT/FRIDAY AS A SURFACE RIDGE TO THE WEST BUILDS
OVER THE AREA. KAM
&&
.AVALANCHE...PREVIOUS DISCUSSION...THE MAJOR WARM FRONT WITH
MOISTURE OF TROPICAL ORIGINS SHOULD MOVE TO THE NW TUESDAY NIGHT AND
MOST OF WEDNESDAY. MOTHER NATURE IS ABOUT TO APPLY MAJOR RAIN AND
WARMING TO WHAT APPEARS TO BE A DEEP LARGELY UNCONSOLIDATED WINTER
SNOWPACK THAT HAS NOT EXPERIENCED SIGNIFICANT RAIN OR WARMING. TOTAL
SNOW DEPTHS ARE AT WINTER MAXES YESTERDAY AND TODAY AT SEVERAL
LOCATIONS IN THE CENTRAL AND SOUTH CASCADES. THE CASCADES HAD 10-20
FEET OF SNOWFALL LATE FEBRUARY TO LATE MARCH AND IT HAS REMAINED
COOL SINCE. THE RAIN AND WARMING WILL LOAD AND WEAKEN SURFACE AND
UPPER SNOW PACK LAYERS AND SHOULD CAUSE AVALANCHES ON WEDNESDAY.
INITIAL SURFACE AVALANCHES MAY CAUSE RELEASES TO LAYERS FROM EARLIER
IN MARCH OR FEBRUARY OR EVEN JANUARY. MODELS VARY BUT THESE
CONDITIONS MAY LAST INTO THURSDAY AS WELL. THE 12 UTC 29 MARCH GFS40
KM SHOWS OVER 9 INCHES OF RAIN IN THE NORTH TO CENTRAL CASCADES FOR
THE 48 HOURS ENDING THURSDAY NIGHT. WARNING ISSUED FOR EXTREME
AVALANCHE DANGER ON WEDNESDAY. AVOID ALL AVALANCHE TERRAIN
