AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
212 PM PDT SAT SEP 10 2005

.SYNOPSIS...A COOL UPPER LEVEL LOW PRESSURE SYSTEM OVER THE PACIFIC
NORTHWEST WILL KEEP A COOL MOIST AND UNSTABLE AIR MASS OVER SOUTHWEST
WASHINGTON AND NORTHWEST OREGON THROUGH THIS EVENING. THE LOW WILL
LINGER INTO SUNDAY THEN WEAKEN AND MOVE EAST. ANOTHER TROUGH OF LOW
PRESSURE IS EXPECTED TO MOVE SOUTHEAST INTO THE FORECAST AREA TOWARDS
THE END OF NEXT WEEK.
&&

.SHORT TERM...A COOL UPPER LOW IS WELL ENTRENCHED OVER WASHINGTON AND
NORTHWEST OREGON...WITH A DECENT SHORT WAVE WRAPPING BACK AROUND THE
BACKSIDE OF THE LOW AND SOUTH THROUGH WESTERN WASHINGTON AND WESTERN
OREGON THIS AFTERNOON. THE SHORT WAVE IS KICKING OFF QUITE A NUMBER
OF SHOWERS...SOME OF WHICH HAVE DEVELOPED INTO THUNDERSTORMS. SO FAR
HAVE SEEN LIGHTNING NEAR RAYMOND WASHINGTON...EAST OF GRESHAM... NEAR
STAYTON...EAST OF SPRINGFIELD...AND EAST OF COOS BAY. WITH FREEZING
LEVELS NEAR 6500 TO 7000 FEET...THIS IS LOW ENOUGH TO SEE A FAIRE
AMOUNT OF SMALL HAIL AROUND.

THE SHORT WAVE MOVES SOUTH OF OUR AREA LATER TONIGHT...AND THE
SHOWERS SHOULD THEN DECREASE. WE ARE STILL CLOSE ENOUGH TO THE LOW
SUNDAY TO SEE SOME AFTERNOON AND EVENING SHOWERS MAINLY ON THE
CASCADES. IF THE WINDS ARE A BIT MORE NORTHEASTERLY THAN NORTHERLY
COULD SEE A FEW SHOWERS DRIFT INTO THE VALLEYS IN THE EVENING... BUT
WILL WAIT BEFORE ADDING THAT FOR NOW. ON MONDAY WE LOOK TO BE IN
BETWEEN SYSTEMS AS THE LOW MOVES OFF TO THE EAST AND THE NEXT PIECE
OF ENERGY STAYS OFF THE COAST AS IT HEADS SOUTH. LIGHT ONSHORE FLOW
SHOULD KEEP SOME MARINE INFLUENCE ACTIVE.

HAVE INDICATED SOME PATCHY FOG THE NEXT 2 NIGHTS. THE AMOUNT OF
PRECIPITATION TONIGHT COULD CAUSE THE COVERAGE TO BE HIGHER FOR
TONIGHT. WE ARE NOW GETTING INTO THE LONGER NIGHTS AND IF THE GROUND
GETS WET ENOUGH...WE WILL SEE MORE FOG. TOLLESON
&&

.LONG TERM...EXTENDED MODELS CONTINUE TO SHOW REASONABLE AGREEMENT IN
MAIN FEATURES...THOUGH VARYING TOO MUCH FOR COMFORT ON TIMING AND
STRENGTH OF FEATURES LATER NEXT WEEK. IT APPEARS SOME SORT OF TROUGH
DEVELOPS LATER NEXT WEEK AROUND THE PACIFIC NORTHWEST...WHICH SHOULD
BRING A LITTLE UNSETTLED WEATHER. SUSPECT TROPICAL ACTIVITY IN THE
WESTERN PACIFIC IS STILL HAMPERING DOWNSTREAM PREDICTABILITY. HAVE
LEFT THE LONGER RANGE MOSTLY UNCHANGED FOR NOW. TOLLESON
&&

.AVIATION...VFR CIGS WILL DOMINATE DURING THE EVENING WITH LOCAL MVFR
CIGS AND VIS WITH THUNDERSTORMS.  STABILIZATION OVERNIGHT WILL LIKELY
LEAD TO AREAS OF FOG AND/OR LOW LEVEL STRATUS DEVELOPING LATE TONIGHT
AND EARLY SUN MORNING.
