AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
920 PM PM PDT MON OCT 20 2014
.SYNOPSIS...SHOWERS WILL DECREASE LATER TONIGHT AS AN UPPER TROUGH
MOVES INLAND. A STRONG FRONTAL SYSTEM WILL BRING RAIN AND WIND TO
THE COAST TUESDAY AFTERNOON AND TO THE INTERIOR OF WESTERN
WASHINGTON BY TUESDAY NIGHT. WEDNESDAY WILL ALSO BE A WET DAY OVER
WESTERN WASHINGTON...ESPECIALLY IN THE MOUNTAINS AS STRONG SOUTHWEST
FLOW ALOFT PERSISTS. UNSETTLED WEATHER WILL CONTINUE FOR THE REST OF
THE WEEK AS A SERIES OF WEATHER SYSTEMS MOVE ONSHORE.
&&
.SHORT TERM...SHOWERS AND A FEW THUNDERSTORMS OVER WESTERN
WASHINGTON THIS EVENING WILL TAPER OFF OVERNIGHT. THE MAIN AREA OF
TSTMS OCCURRED BETWEEN THE SOUTH TIP OF WHIDBEY AND THE ARLINGTON
AREA...AND THE CAMANO ISLAND RADAR SHOWED UP TO 0.75 INCHES OF RAIN
IN SOME LOCATIONS OF WRN SNOHOMISH COUNTY FROM THE HEAVY SHOWERS.
THE NEXT FRONTAL SYSTEM IS FAST APPROACHING THE AREA AND THE LEADING
FRONTAL BAND IS CROSSING 130W THIS EVENING WITH A STRONG WESTERLY
JETSTREAM CHASING THE SYSTEM ACROSS THE NORTH PACIFIC ALONG 45N.
THIS NEXT FRONTAL SYSTEM SHOULD PRODUCE WINDS IN THE CATEGORY OF A
WIND ADVISORY TUE AFTERNOON AND EVENING FOR THE COAST AND ALL AROUND
THE SAN JUANS. THE NAM TAKES A 996MB LOW ACROSS 130W AROUND 8PM AND
THAT GETS DOWN TO 991MB BY THE TIME IT REACHES VANCOUVER ISLAND
AROUND 2AM. THE 00Z GFS40 DOESN'T SHOW MUCH IN THE WAY OF SECONDARY
DEVELOPMENT BUT THE UW WRFGFS HINTS AT A LITTLE SOMETHING. SUSTAINED
WINDS ALONG THE COAST AND IN THE NORTHERN INLAND WATERS WILL BE
GALES...AND THE UW 10M WIND GUSTS FORECAST SHOWS WINDS OVER THE
COASTAL WATERS PERHAPS AS HIGH AS 60KT WITH 40KT OR 45MPH GUSTS OVER
LAND. THE OTHER THING TO WATCH WITH THIS SYSTEM IS THE AMOUNT OF
RAIN THAT CARRIES OVER INTO WEDNESDAY...ESPECIALLY IN THE
MOUNTAINS...IN STRONG SW FLOW ALOFT. THE RAIN DOES APPEAR LIKELY TO
BE HEAVY ENOUGH TO GET THE SKOKOMISH UP TO FLOOD STAGE.
.LONG TERM...FRIDAY WILL BE IN BETWEEN WEATHER SYSTEMS WITH JUST A
SMALL CHANCE OF RAIN. THE GFS AND ECMWF ARE IN PRETTY GOOD AGREEMENT
SHOWING ANOTHER SHOT OF RAIN FRIDAY NIGHT AND SATURDAY AS A FRONTAL
SYSTEM MOVES THROUGH. A WEAK UPPER RIDGE WILL MOVE OVER THE AREA
SUNDAY AND MONDAY FOR DRIER AND MORE TRANQUIL WEATHER. SCHNEIDER
&&
.HYDROLOGY...A VIGOROUS FRONTAL SYSTEM IS EXPECTED TO BRING HEAVY
RAINS TO THE AREA TUESDAY NIGHT. THE HIGHEST AMOUNTS ARE FORECAST TO
BE OVER THE OLYMPICS WHERE UP TO 5 INCHES ARE POSSIBLE BY WEDNESDAY
MORNING. THIS WILL LIKELY PUSH THE SKOKOMISH RIVER IN MASON COUNTY
TO FLOOD STAGE ON WEDNESDAY. A HYDROLOGIC OUTLOOK IS CURRENTLY OUT
TO COVER THIS POSSIBILITY. FOR OTHER AREAS RIVERS...FLOODING IS
UNLIKELY OVER THE NEXT 7 DAYS.
&&
.AVIATION...A TROUGH OVER THE PAC NW TONIGHT WILL WEAKEN AND SHIFT E
OF TUESDAY. THE NEXT LOW PRESSURE SYSTEM WILL DEVELOP OFFSHORE
TUESDAY AFTERNOON WITH A WARM FRONT LIFTING ACROSS THE AREA. A 990
MB SURFACE LOW WILL TRACK INTO CENTRAL VANCOUVER ISLAND TUESDAY
NIGHT....DRAGGING A FRONT THROUGH WRN WA. LIGHT TO MODERATE SW FLOW
ALOFT...BECOMING STRONG S-SW FLOW ALOFT BY TUESDAY AFTERNOON. MOIST
ATMOSPHERE AND UNSTABLE...BECOMING SOMEWHAT STABLE AFTER MIDNIGHT
TONIGHT. SHOWERS AND ISOLATED THUNDERSTORMS...THEN SHOWERS
DECREASING AFTER MIDNIGHT. RAIN DEVELOPING TUESDAY AFTERNOON WITH

TUESDAY AFTERNOON AND TUESDAY NIGHT. DTM

THROUGH TUESDAY. COMBINED SEAS MAY REACH 15-16 FT TUESDAY NIGHT.
