AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
232 AM PST SUN NOV 27 2011
.SYNOPSIS...A RATHER STRONG FRONTAL SYSTEM IS OFF THE COAST EARLY
THIS MORNING AND WILL MOVE ONTO THE COAST LATER THIS MORNING...INTO
THE NORTH INTERIOR LATE THIS MORNING AND EARLY AFTERNOON...AND INTO
THE SOUTHERN WILLAMETTE VALLEY LATER TODAY AND THIS EVENING. THE
FRONT WILL MOVE EAST OF THE CASCADES LATER THIS EVENING. THE FRONT
WILL BRING A GOOD SHOT OF WIND TO THE COAST TODAY...WITH DECENT
RAINFALL AND SOME SNOW TO THE CASCADES AS THE SNOW LEVEL DROPS BELOW
THE PASSES LATER IN THE EVENT. HIGHER PRESSURE WILL BRING DRYING ON
MONDAY THAT WILL CONTINUE INTO TUESDAY. ANOTHER COOL SYSTEM WILL DROP
IN FROM THE NORTHWEST TUESDAY NIGHT AND WEDNESDAY FOR A BRIEF SHOT OF
VALLEY RAIN AND MOUNTAIN SNOW. ANOTHER UPPER RIDGE WILL BRING ANOTHER
DRY PERIOD FOR THE END OF THE WEEK.
&&
.SHORT TERM...THE SLOW MOVING SOUTHWEST TO NORTHEAST ORIENTED FRONTAL
ZONE REMAINS OFF THE COAST EARLY THIS MORNING...WITH THE MAIN
PRECIPITATION REMAINING OFFSHORE AND TO OUR NORTH. HOWEVER... THE
MODELS INDICATE THE FRONT WILL BEGIN MOVING TODAY...PUSHING ONTO THE
COAST LATER THIS MORNING...INTO THE PORTLAND AREA IN THE LATE MORNING
AND EARLY AFTERNOON...AND INTO EUGENE BY LATER IN THE AFTERNOON.
THE FRONT MOVES EAST OF THE CASCADES THIS EVENING. THE FRONT IS
RATHER VIGOROUS...AND WILL PRODUCE A GOOD SHOT OF WIND NEAR THE COAST
BUT LIKELY STAY JUST BELOW HIGH WIND CRITERIA EVEN AT THE HEADLANDS.
THIS FRONTAL ZONE ALSO HAS PRECIPITABLE WATER VALUES FEEDING INTO
WELL ABOVE ONE INCH...AND WITH 40 TO 50 KT 850 MB FLOW THE MODELS
HAVE SOME PRETTY DECENT RAINFALL TOTALS. THE FRONT MOVES THROUGH
RATHER QUICKLY...SO NO MAJOR HYDRO ISSUES ANTICIPATED UNLESS RAINFALL
RATES ARE HIGH ENOUGH TO CAUSE SOME LOCAL PONDING OF WATER. SNOW
LEVELS DROP AS THE SYSTEM MOVES THROUGH...AND SHOULD SEE SOME SNOW
ACCUMULATIONS BUT DO NOT DROP BELOW PASS ELEVATIONS UNTIL LATE IN THE
EVENT. SO ACCUMULATIONS WILL TEND TO STAY BELOW ADVISORY AMOUNTS.
ONSHORE FLOW WANES QUICKLY BEHIND THE FRONT...SO LINGERING SHOWERS
SHOULD END EARLY MONDAY AS HIGHER PRESSURE BUILDS IN. IT MAY TAKE A
WHILE FOR CLOUDS TO CLEAR ON MONDAY.
DRY WEATHER WILL CONTINUE MONDAY NIGHT AND MOST OF TUESDAY AS A FLAT
UPPER RIDGE IS OVER THE AREA. THE NEXT SYSTEM IS A TIGHT LITTLE LOW
THAT DROPS IN FROM THE NORTHWEST...APPROACHING THE COAST LATE
TUESDAY...AND MOVING THROUGH OUR FORECAST AREA TUESDAY NIGHT AND
EARLY WEDNESDAY FOR ANOTHER SHOT OF VALLEY RAIN AND MOUNTAIN SNOW.
TOLLESON
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...
MODEL AGREEMENT IS GOOD THAT A FAST MOVING SHORTWAVE WILL SWING
THROUGH THE REGION ON TUE NIGHT AND EARLY WED. THIS SHOULD BRING A
QUICK SHOT OF PRECIPITATION...WITH SNOW LEVELS FALLING TO NEAR OR
BELOW CASCADE PASS LEVELS. BEHIND THE DEPARTING TROUGH...UPPER LEVEL
RIDGING IS FCST TO BECOME REESTABLISHED OVER THE EASTERN PACIFIC FOR
THE SECOND HALF OF THE WEEK INTO NEXT WEEKEND. THIS SHOULD MEAN
MAINLY DRY CONDITIONS AS AN OFFSHORE FLOW PATTERN DEVELOPS OVER THE
REGION. JFP
&&
.AVIATION...OFFSHORE FLOW WILL KEEP CONDITIONS VFR ACROSS MUCH OF THE
AREA THIS MORNING. MVFR CONDITIONS WILL DEVELOP ALONG THE COAST BY
15Z THIS MORNING AND ACROSS THE INTERIOR AROUND 20Z THIS AFTERNOON AS
A COLD FRONT PUSHES INLAND. MVFR IS LIKELY TO CONTINUE INTO THE
EVENING HOURS WITH A MIX OF VFR AND MVFR EXPECTED TONIGHT.
KPDX AND APPROACHES...VFR CONDITIONS ARE EXPECTED THROUGH THE
MORNING. CLOUDS WILL LOWER DURING THE DAY TODAY WITH CONDITIONS
DETERIORATING TO MVFR WITH RAIN DURING AFTERNOON AND EVENING.
&&
.MARINE...A SLOW MOVING COLD FRONT APPROACHING THE COAST THIS MORNING
WILL BRING GALE FORCE WINDS TO THE WATERS UNTIL MIDDAY WHEN IT
FINALLY MOVES ASHORE. WINDS WILL DROP OFF BEHIND THE FRONT BUT SEAS
WILL BE SLOWER TO DROP OFF. HIGH PRESSURE WILL BUILD OVER THE WATERS
TONIGHT AND MONDAY. A MUCH WEAKER SYSTEM MAY AFFECT THE WATERS
TUESDAY NIGHT AND WEDNESDAY BEFORE THINGS QUIET DOWN THROUGH THE END
OF THE WEEK.
&&
