AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
336 AM PDT FRI OCT 30 2015

.SYNOPSIS...A STRONG PACIFIC FRONTAL SYSTEM WILL BRING RAINY AND
WINDY WEATHER TODAY THROUGH SATURDAY. A COOL UPPER TROUGH WILL CROSS
THE REGION ON SUNDAY FOR SHOWERS. A STRONG UPPER RIDGE OFFSHORE WILL
BRING DRIER WEATHER NEXT WEEK.

&&

.SHORT TERM...AN ATMOSPHERIC RIVER IS AIMED AT WESTERN WA AND MOIST
WESTERLY FLOW WILL SLAM THROUGH THE REGION TODAY THROUGH SATURDAY.
THIS WILL LEAD TO A PERIOD OF VERY WET WEATHER ESPECIALLY FOR THE
COAST...OLYMPICS AND WEST SLOPES OF THE CASCADES. THE FIRST WAVE IS
ASSOCIATED WITH A STRONG WARM FRONT THAT WILL MOVE INLAND TODAY THEN
STALL OVER THE AREA TONIGHT. A COLD FRONT WILL BRING ANOTHER SHOT OF
HEAVY RAIN AS IT SHIFTS S/SE THROUGH WESTERN WA ON SATURDAY. STEADY
HEAVY RAIN WILL TAPER OFF FROM THE NORTH TO SOUTH LATE SATURDAY
AFTERNOON OR EVENING AS THE FRONT PUSHES INTO OREGON. RIVERS FLOWING
OFF THE OLYMPICS AND WEST SLOPES OF THE CASCADES WILL SEE SHARP
RISES WITH FLOODING POSSIBLE...A FLOOD WATCH REMAINS IN EFFECT. SEE
HYDROLOGY DISCUSSION.

EXPECT 1-4 INCHES OF RAIN ALONG THE COAST TODAY THROUGH SATURDAY.
THE INTERIOR WILL SEE 1-3 INCHES...WITH HEAVIEST AMOUNTS OVER THE
SOUTHWEST INTERIOR AND NEAR THE CASCADES. IT WILL BE BREEZY TO WINDY
DURING THIS PERIOD AS WELL.

SATURDAY NIGHT AND SUNDAY WILL BE SHOWERY AS A COOL UPPER LEVEL LOW
MOVES IN. SNOW LEVELS WILL DROP TO AROUND 4000 FEET ON SUNDAY
WITH A FEW INCHES OF SNOW POSSIBLE IN THE MOUNTAINS.

A STRONG UPPER LEVEL RIDGE WILL FORM OVER THE NE PAC ON MONDAY WITH
NORTHERLY FLOW ALOFT OVER WESTERN WA. MODELS SHOW A WEAK UPPER LEVEL
DISTURBANCE IN THE FLOW FOR A CHANCE OF SHOWERS. 33

.LONG TERM...AN UPPER LEVEL RIDGE WILL NUDGE EAST AND INLAND TUESDAY
THROUGH THURSDAY FOR DRY BUT COOL WEATHER. TEMPS WILL BE A FEW
DEGREES BELOW NORMAL WITH HIGHS NEAR 50 AND LOWS IN THE MID 30S TO
LOWER 40S. THE RIDGE MAY BREAK DOWN LATE NEXT WEEK AS A WEAK WARM
FRONT MOVES IN. 33

&&

.HYDROLOGY...MODEL RAINFALL TODAY AND SATURDAY HAS INCREASED OVER
THE LAST FEW RUNS. IN ADDITION SOME MESOSCALE MODELS SHOW A
PRONOUNCED ATMOSPHERIC RIVER AIMED AT THE SOUTHERN CASCADES LATE
FRIDAY NIGHT AND SATURDAY MORNING. THE PRECIPITATION BULLSEYE OVER
MOUNT RAINIER IS MORE THAN 20 INCHES IN 48 HOURS IN THE WETTEST
MESOSCALE MODELS. THERE ARE LOWER AMOUNTS IN OTHER MESOSCALE MODELS.
THE FORECAST QPF REMAINS A BLEND OF THE MESOSCALE MODELS WHICH
YIELDS 12-15 INCHES OVER MOUNT RAINIER AND 4-8 INCHES OVER THE REST
OF THE CASCADES AND THE OLYMPICS.

THIS IS THE FIRST HYDROLOGICAL EVENT OF THE SEASON AND RIVERS WILL
RESPOND SLOWER THAN USUAL AND WILL NOT RISE AS FAR AS THEY WOULD
LATER IN THE SEASON. HOWEVER THE CURRENT QPF GIVES MINOR FLOODING ON
SEVERAL RIVERS FROM THE SKAGIT SOUTH TO THE COWLITZ...WITH MODERATE
FLOODING ON THREE RIVERS FLOWING OFF MOUNT RAINIER...THE
CARBON...THE NISQUALLY AND THE WHITE RIVER.

THE SNOQUALMIE RIVER AT CARNATION IS ALSO FORECAST TO REACH MODERATE
FLOOD STAGE. NO RIVERS ON THE OLYMPIC PENINSULA ARE FORECAST TO
FLOOD YET...WITH THE POSSIBLE EXCEPTION OF THE SKOKOMISH RIVER IN
MASON COUNTY.

THERE IS CONSIDERABLE UNCERTAINTY ABOUT THE AMOUNT AND EXACT
LOCATION OF RAINFALL THIS WEEKEND. HOWEVER IT SEEMS SURE THAT LOTS
OF RAIN WILL FALL...ESPECIALLY IN THE MOUNTAINS. A FLOOD WATCH
REMAINS IN EFFECT FOR MOST OF WESTERN WASHINGTON.

&&

.AVIATION...WESTERLY FLOW ALOFT BECOMING STRONG THIS AFTERNOON AND
REMAINING STRONG THROUGH SATURDAY. AIR MASS MOIST AND STABLE.

AREA THIS MORNING WITH CEILINGS LOWERING DOWN TO 1000-2000 FEET WITH
THE FRONT. VISIBILITIES ALSO LOWERING TO 3-5SM IN LIGHT TO MODERATE
