AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PORTLAND OR 820 AM PST WED NOV 11 2009 .SYNOPSIS...UNSETTLED WEATHER WILL CONTINUE FOR THE PACIFIC NORTHWEST FOR THE REMAINDER OF THE WEEK AS A BROAD COOL UPPER LEVEL LOW PRESSURE SYSTEM CONTINUES TO CHURN OVER THE NORTHEAST PACIFIC... SENDING A SERIES OF DISTURBANCES INTO WASHINGTON AND OREGON. A WEAKENING FRONTAL ZONE WILL SLOWLY MOVE THROUGH OUR FORECAST AREA TODAY. THIS WILL BE FOLLOWED BY A LOW DROPPING DOWN OUT OF THE GULF OF ALASKA AND INTO OUR AREA TONIGHT AND OFF TO THE EAST ON THURSDAY. ANOTHER COOL AND POSSIBLY EVEN STRONGER SYSTEM WILL DROP DOWN FROM THE NORTHWEST LATER THURSDAY NIGHT AND FRIDAY. THE CASCADES WILL SEE SIGNIFICANT ACCUMULATIONS OF SNOW OVER THE NEXT FEW DAYS. && .SHORT TERM...A FRONTAL BAND THAT MOVED IN OVERNIGHT HAS PUSHED EAST OF THE AREA THIS MORNING...EXCEPT FOR THE SOUTHERN CASCADE ZONES SO THESE AREAS WILL CONTINUE TO HAVE SHOWERS THROUGH THE MORNING. ANOTHER BAND OF SHOWERS FROM EASTERN MULTNOMAH COUNTY TO NW BENTON COUNTY WILL SHIFT EAST THIS MORNING. LIGHT SHOWERS WILL CONTINUE TODAY.

SNOW LEVELS WILL A LITTLE BELOW THE PASSES TODAY...BUT IT APPEARS AMOUNTS WILL BE A BIT BELOW ADVISORY CRITERIA. STILL IT WILL BE ENOUGH SNOW TO AFFECT TRAVEL SOME. MH ATTENTION THEN QUICKLY TURNS TO A LOW DROPPING DOWN THE B.C. COAST FROM THE GULF OF ALASKA. THIS POTENT AND COMPACT LITTLE LOW WILL BRING MORE SHOWERS TO OUR AREA TONIGHT AND THURSDAY MORNING...AND WITH A SIGNIFICANT COLD POOL ALOFT COULD PRODUCE A FEW THUNDERSTORMS NEAR THE COAST AND ACROSS OUR NORTH INTERIOR ZONES. THIS SYSTEM ALSO HAS A CHANCE OF PRODUCING ENOUGH SNOW IN THE CASCADES TO WARRANT AN ADVISORY LATE TONIGHT AND EARLY THURSDAY. SNOW LEVELS WILL BE LOW ENOUGH FOR SOME ACCUMULATION ALSO IN THE HIGHER COASTAL MOUNTAINS AND IN THE CASCADE FOOTHILLS. THE SHOWERS WILL DECREASE LATER IN THE DAY AS THIS SYSTEM MOVES EAST OF THE CASCADES. THIS WILL BE FOLLOWED BY ANOTHER RATHER COLD FRONTAL SYSTEM ALSO DROPPING DOWN FROM THE NORTHWEST FOR LATER THURSDAY NIGHT AND FRIDAY.

SNOW LEVELS BEGIN RISING TO NEAR 6000 FT OVER THE WEEKEND AS MODELS SUGGEST A SLIGHT BREAK IN THE WET CONDITIONS. MODELS HINT AT A BRIEF UPPER RIDGE DURING THIS BREAK... WHICH IS SQUEEZED OUT BY A SECOND SYSTEM AROUND SAT. ALTHOUGH MODELS AGREE SEVERAL SYSTEMS WILL SWEEP THROUGH THE REGION...MODELS DISAGREE ON THE EXACT TIMING. ITS POSSIBLE MORE THAN ONE BREAK WILL OCCUR DURING THE WEEKEND...HOWEVER...KEPT CHANCE OF POP IN GRIDS GIVEN CLIMATOLOGY AND UNCERTAINTY OF MODELS.
