AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
904 AM PDT SUN OCT 24 2010
.SYNOPSIS...A VERY DEEP LOW PRESSURE CENTER CLOSE TO 960 MB WAS OFF
OF NORTHERN VANCOUVER ISLAND THIS MORNING...WHILE THE STRONG COLD
FRONT HAS DROPPED SOUTHEAST OF THE FORECAST AREA. SNOW LEVELS WILL
FALL TO NEAR CASCADE PASS LEVELS LATER TODAY. THE SURFACE LOW WILL
STALL AND SLOWLY BEGIN TO WEAKEN TODAY...BUT STRONG WESTERLY ONSHORE
FLOW WILL CONTINUE TO BE AIMED AT THE PACIFIC NORTHWEST THROUGH
MONDAY MORNING. THE LOW WILL FINALLY MOVE ONSHORE AND CONTINUE
WEAKENING MONDAY NIGHT AND TUESDAY...WITH THE ONSHORE FLOW INTO THE
PACIFIC NORTHWEST FINALLY EASING. THERE WILL BE A LULL IN THE SHOWERS
ON WEDNESDAY...THEN THE NEXT SYSTEM WILL MOVE ONSHORE WEDNESDAY NIGHT
AND THURSDAY. AFTER THAT...UNSETTLED CONDITIONS ARE EXPECTED THROUGH
NEXT WEEKEND.
&&
.SHORT TERM...THE SURFACE LOW HAS DEEPENED TO NEAR 960 MB THIS
MORNING AS IT MOVED OFFSHORE OF NORTHERN VANCOUVER ISLAND. THE LOW
SHOULD STALL THERE TODAY AND BEGIN TO FILL A LITTLE...BUT VERY STRONG
WESTERLY FLOW CONTINUES OVER THE EASTERN PAC POINTED INTO THE PAC NW.
MODELS SUGGEST SOME WIND GUSTS MAY APPROACH 50KT ON THE COAST AND
HIGHER COAST RANGE AS SHOWERS AND TSTMS MOVE ONSHORE TODAY AND
TONIGHT...AND POSSIBLY INTO MON MORNING. THE HIGHER CASCADES WILL
ALSO BE EXPOSED TO THE STRONG W WINDS ALOFT. SOUTHERLY GRADIENTS WILL
GIVE GUSTY WINDS TO INLAND VALLEYS AS WELL. THE WINDS WILL BEGIN TO
EASE MON AS THE SURFACE LOW BEGINS TO FILL AND THE GRADIENT STARTS TO
RELAX.
THE MOIST FRONT DROPPED SE OF THE AREA EARLY THIS MORNING...AND WE
WILL SEE COLDER AIR ALOFT MOVING IN THIS AFTERNOON. LAPSE RATES ARE
STEEP ENOUGH FOR A MENTION OF TSTMS MOST AREAS EXCEPT THE CASCADES.
HAVE ALREADY HAD STRIKES ON THE COAST LOCALLY INTO THE COAST RANGE.
THE MODELS SUGGEST THAT THIS WILL BE A POSSIBILITY AGAIN MON
AFTERNOON AND EARLY EVENING.
THE ONSHORE FLOW IN CONJUNCTION WITH SNOW LEVELS LOWERING TO NEAR
PASS ELEVATIONS LATER TODAY AND TONIGHT WILL RESULT IN WINTER STORM
SNOW AMOUNTS OVER THE CASCADES ABOVE ABOUT 4000 FT. THE ONSHORE
SHOULD FINALLY WEAKEN TUE AND TUE NIGHT AS THE STRONG SURFACE LOW
FINALLY MOVES INTO B.C. AND WEAKENS SIGNIFICANTLY. SNOW LEVELS WILL
FALL TO NEAR 3500 FT OR POSSIBLY 3000 FT MON NIGHT AND TUE...BUT
AMOUNTS AT THOSE ELEVATIONS WILL BE CONSIDERABLY LESS. RW
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...
GUIDANCE IN GOOD AGREEMENT SHOWING BRIEF SHORT WAVE RIDGING ON WED
FOR DRY CONDITIONS. THEN MODELS IN EXCELLENT AGREEMENT SHOWING AN
UPPER LOW DEVELOPING OVER THE EASTERN PAC SENDING THE NEXT BATCH OF
PRECIP INLAND MAINLY OVER NORTHERN CA... BUT POTENTIALLY ALSO
SPREADING RAIN INTO THE PAC NW WEDNESDAY NIGHT AND THURSDAY. BY THE
END OF THE WEEK MODELS SHOW THE UPPER LOW OPENING UP AND SHIFTING
INLAND FOR A CONTINUED THREAT OF RAIN AND MOUNTAIN SNOW...ALTHOUGH
MODELS GENERALLY SHOW THE MAIN ENERGY CONTINUING S OF THE DISTRICT.
RW/PT
&&
.AVIATION...UNSTABLE AIR MASS MOVING INTO AREA WITH THUNDERSTORM
ACTIVITY MAINLY IN THE NORTH COAST AND COAST RANGE BUT STILL
POSSIBLE FURTHER INLAND THROUGH THIS EVENING AS WELL. VFR EXPECTED
TO DOMINATE THOUGH THUNDERSTORMS AND STRONGER SHOWERS WILL BRING
MVFR CIGS AND VIS AS THEY MOVE THROUGH.
KPDX AND APPROACHES...VFR CONDITIONS SHOULD PREVAIL TODAY WITH
MVFR SHOWERS AND MAYBE EVEN A TSTM.
&&
.MARINE...FRONT MOVED INLAND EARLY THIS MORNING WITH SOUTHWEST
WIND GUSTING INTO THE GALE CATEGORY THROUGH TONIGHT. GALES MAY
CONTINUE INTO MONDAY AFTERNOON IN THE NORTHERN WATERS THOUGH

TO 30 FT THIS AM...THEN 30 TO 35 FT LATER THIS AFTERNOON...WITH
THE LARGEST SWELL IN THE N WATERS. SEAS FINALLY DROP BELOW 20 FT
