AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
227 AM PDT THU AUG 19 2010
.SYNOPSIS...COOLER WEATHER PATTERN TAKES OVER THROUGH THE REMAINDER
OF THE WEEK. THE ARRIVAL OF AN UPPER LEVEL LOW TO THE PACIFIC
NORTHWEST HAS INDUCED A RATHER STRONG MARINE PUSH. EXPECT COOLER
TEMPERATURES AND AN ABUNDANCE OF CLOUDS TO PREVAIL THROUGH THE
WEEKEND AS THE EXTENDED MODELS SHOW AN UPPER TROUGH SETTING UP NEAR
THE PACIFIC NORTHWEST COAST FRIDAY AND LASTING THROUGH THE WEEKEND.
&&
.SHORT TERM...SATELLITE IMAGERY...IR AND WATER VAPOR...SHOW A WEEK
SHORT WAVE DROPPING INTO THE PACIFIC NORTHWEST THIS MORNING. THIS IS
RESULTING IN A DEEPENING OF THE MARINE LAYER AND QUICKER PENETRATION
INTO THE INTERIOR THIS MORNING. A SERIES OF SHORTWAVE WILL CARVE OUT
AN UPPER TROUGH ALONG THE COAST THAT WILL LAST INTO THE WEEKEND.
SHOULD SEE EVEN MORE DEEPENING OVER THE WEEKEND AS THE UPPER TROUGH
BEGINS TO MOVE EASTWARD. THUS CONTINUED ONSHORE FLOW WITH NIGHT AND
MORNING CLOUDS INTERIOR AND WITH ONLY PARTIAL AFTERNOON CLEARING
ALONG THE COAST. TEMPERATURES OVER THE INTERIOR MILD COMPARED TO
RECENT HOT WEATHER. SS
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS.
AT THE BEGINNING OF THE LONG TERM PERIOD ON SAT NIGHT...MODEL
AGREEMENT IS FAIRLY GOOD IN POSITIONING AN UPPER LEVEL TROUGH AXIS
JUST WEST OF THE PAC NW COAST. THE MODELS HAVE THIS TROUGH MOVING
ONSHORE OVERNIGHT SAT INTO SUN. THIS SHOULD BRING PLENTY OF CLOUDS
AND THE CHANCE FOR SOME SHOWER ACTIVITY ALONG THE COAST RANGE AND
CASCADES IN NW OREGON AND S WASHINGTON ON SUN. TEMPS ON SUN SHOULD
CONTINUE TO RUN 5 TO 10 DEGREES BELOW SEASONAL NORMS FOR INLAND
LOCATIONS. UPPER LEVEL RIDGING BUILDS IN BEHIND THE DEPARTING UPPER
TROUGH...ALLOWING TEMPS TO RECOVER TO NEAR OR SLIGHTLY ABOVE
SEASONAL AVERAGES FOR MON AND TUE. IT APPEARS THAT ANOTHER UPPER
TROUGH WILL DROP DOWN OUT OF THE GULF OF ALASKA SOMETIME ON WED. JFP
&&
.AVIATION...THE MARINE INVERSION IS DEEPER THIS MORNING COMPARED
TO TUE AS A SHORTWAVE MOVES INLAND...SO EXPECT A MIX OF MVFR AND IFR
CONDITIONS TO PREVAIL FOR THE COAST. MVFR CIGS HAVE ALREADY
DEVELOPED INLAND WITH CIGS SETTLING AROUND 2000 TO 2500 FEET.
EXPECT STRATUS TO LIFT BY MID DAY AGAIN...WITH THE COAST REMAINING
IN MVFR CIGS MOST OF TODAY.
KPDX AND APPROACHES...MVFR CIGS CONTINUE THROUGH THIS
MORNING...LIFTING TO VFR CONDITIONS AROUND 20Z.
&&
.MARINE...HIGH PRESSURE WILL REMAIN CENTERED WELL OFFSHORE WITH
LOWER PRESSURE INLAND THROUGH THE WEEKEND. A WEAK COLD FRONT WILL
MOVE ACROSS THE WATERS ON FRIDAY. THE ROUGH COLUMBIA RIVER BAR
SMALL CRAFT ADVISORY TONIGHT IS DUE MAINLY TO THE SHORT PERIOD
DURING THE STRONGER EBB. SMALL CRAFT ADVISORY FOR WINDS ALONG THE
OUTER WATERS AND SOUTHERN INNER WATERS WILL OCCUR LATER TONIGHT.
IT SHOULD BE SHORT LIVED...WITH LEVELS DROPPING BELOW CRITERIA BY
EARLY FRIDAY MORNING. LR
&&
.PQR WATCHES/WARNINGS/ADVISORIES...
OR...NONE.
WA...NONE.
PZ...SMALL CRAFT ADVISORY FOR WINDS FROM 5 PM THIS AFTERNOON TO 5 AM
