SYNOPSIS
A DRAPED STATIONARY FRONT WILL CONTINUE TO PRODUCE WIDESPREAD
PRECIPITATION ACROSS WESTERN WASHINGTON THROUGH THE WEEKEND,
WITH HEAVIER PRECIPITATION WRAPPING UP BY EARLY SATURDAY
AFTERNOON. BREEZY WINDS ARE ALSO EXPECTED GOING INTO TONIGHT FOR
MOST OF PUGET SOUND AND SOME COASTAL AREAS. CONDITIONS WILL
MOSTLY DRY FOR THE FIRST PART OF NEXT WEEK, ALTHOUGH ACTIVE
WEATHER IS EXPECTED TO RETURN BY MIDWEEK, ALONG WITH COOLER
TEMPERATURES.
SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/
A STATIONARY/WARM FRONT REMAINS DRAPED ACROSS NW WASHINGTON THIS
AFTERNOON, AS AN UPPER LEVEL TROUGH SWINGS THROUGH. MODERATE
RAIN CONTINUES ACROSS PUGET SOUND INTO THE NORTH INTERIOR/CASCADES
THIS AFTERNOON. RAIN RATES OF 0.01-0.10"/HR ARE EXPECTED WITH
THE SHOWER ACTIVITY GOING INTO TONIGHT AND SATURDAY. MOST OF THE
ACTIVITY GOING INTO SATURDAY WILL BE CONFINED TO THE CASCADES
AND OLYMPICS/COAST, WITH AMOUNTS NOT EXPECTED TO BE ANYWHERE
NEAR THE RAIN TOTALS PICKED UP SO FAR FOR FRIDAY. A FEW
LINGERING IMPACTS FROM THE ACCUMULATION OF STEADY RAIN MAY BE
LINGERING (SUCH AS RISES IN STREAMS, SOME PONDING OF ROADWAYS,
UNSTABLE SOILS, ETC.). ADDITIONAL DETAILS ON RIVERS CAN BE FOUND
IN THE HYDROLOGY DISCUSSION BELOW. SNOW LEVELS REMAIN HIGH GOING
THROUGH THE WEEKEND, SO ANY SNOW THAT DOES FALL WILL REMAIN AT
HIGH ELEVATIONS (ABOVE 7,000 FT).
IN ADDITION TO RAIN, BREEZY SOUTHWEST WINDS ARE EXPECTED TO PICK
UP THIS AFTERNOON INTO TONIGHT IN THE WARM SECTOR. THE PRIMARY
WINDY SPOTS WITH THIS SYSTEM ARE PUGET SOUND, AND ALONG THE
PACIFIC COAST, WITH MOST LIKELY AN AREA FROM EVERETT DOWN TO
DUPONT SEEING GUSTS PEAK AROUND MIDNIGHT AT AROUND 30 MPH. THERE
IS A 10% CHANCE THE GUSTS COULD BE AS HIGH AS 35 MPH. THE
CASCADES AND SOUTH INTERIOR WILL SEE BREEZY WINDS NOW THROUGH
EARLY SATURDAY MORNING (AS WINDS ELSEWHERE ALSO DECREASE AROUND
THE SAME TIME).
LATE SATURDAY INTO SUNDAY IS EXPECTED TO REMAIN OVERCAST WITH
SHOWERY CONDITIONS CONTINUING THROUGH THE WEEKEND AS THE UPPER
LEVEL JET ZONES OUT. AGAIN RAIN RATES REMAIN EXTREMELY LIGHT
WITH RATES NOT EXCEEDING A COUPLE HUNDREDTHS OF AN INCH. ANOTHER
FRONT/TROUGH APPROACHES SUNDAY EVENING, WHICH WILL INCREASE THE
CHANCE OF PRECIPITATION REGIONWIDE. THE RATES AGAIN REMAIN
LIGHT, ALTHOUGH THE OLYMPICS/CASCADES COULD SEE THEM APPROACH
0.05-0.10"/HR WITH SOME OROGRAPHIC ENHANCING.
WINDS LATE SATURDAY INTO SUNDAY WILL BECOME VERY LIGHT OUT OF
THE SOUTH (5-10 MPH OR SO). HIGHS IN THE LOWLANDS/COAST TODAY
THROUGH SUNDAY REMAIN IN THE MID 50S, WITH LOWS IN THE MID TO
UPPER 40S.
HPR
LONG TERM /MONDAY THROUGH FRIDAY/
A TROUGH IS EXPECTED TO SWING THROUGH MONDAY WITH THE
CONTINUATION OF THE CHANCE OF ELEVATED SHOWERS. COOL AIR IS
EXPECTED TO FOLLOW THE TROUGH/FRONT MONDAY EVENING AS SNOW
LEVELS FALL TO AROUND 3,500 FT. CHANCES OF PRECIPITATION LATE
MONDAY INTO THE FIRST PART OF WEDNESDAY REMAIN LOW (20-30%).
ENSEMBLES ARE IN GOOD AGREEMENT OF A LOW DROPPING DOWN FROM
ALASKA WEDNESDAY INTO THE END OF THE WEEK, WHICH WILL INCREASE
PRECIPITATION CHANCES TOWARDS THE END OF THE WEEK. TEMPERATURES
WILL DROP CONSIDERABLY POST-FRONT MONDAY NIGHT, WITH HIGHS
THROUGH THE END OF THE WEEK ONLY THE UPPER 40S/LOW 50S, AND SOME
LOW TEMPERATURES WILL LIKELY DIP INTO THE 30S.
