AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PORTLAND OR 203 PM PDT WED AUG 24 2011 .SYNOPSIS...AN UPPER LEVEL LOW COMING UP THE COAST TONIGHT WILL BRING UNSTABLE AIR WITH IT...FOR A CHANCE OF THUNDERSTORMS. DURING THE LATTER HALF OF THE WEEK AND INTO THE WEEKEND...A TROUGH OF LOW PRESSURE LINGERING OFF THE COAST WILL CONTINUE A SOUTHERLY FLOW INTO THE REGION...KEEPING TEMPS WARM WITH THREATS FOR THUNDERSTORMS... MAINLY OVER THE CASCADES. A TROUGH DIGGING DOWN FROM THE NW EARLY NEXT WEEK IS EXPECTED TO BRING A CHANGE TO COOLER WEATHER. && .SHORT TERM...AN UPPER LEVEL TROUGH SEEN IN WATER VAPOR PICTURES BEYOND 130W WILL BE THE DOMINANT WEATHER MAKING FEATURE FOR THE NEXT FEW DAYS. A VORT MAX LIFTING OUT OF THE TROUGH THIS EVENING...NEAR 40N 126W EARLY THIS AFTERNOON...IS EXPECTED TO LIFT ACROSS THE REGION TONIGHT. THE PRESENCE OF ALTOCUMULUS CASTELLANUS CLOUDS AS WELL AS A FEW LIGHTNING STRIKES OVER SW OREGON AND OFF THE OREGON COAST ARE INDICATIVE OF A WIDE AREA OF INSTABILITY AHEAD OF THIS VORT MAX. WITH SURFACE DEWPOINTS IN THE OW 60S...WILL EXTEND THE CHANCES FOR THUNDER TO INCLUDE THE ENTIRE FORECAST AREA THIS EVENING. ALTHOUGH NOT EXPECTED TO MAKE A SERIOUS PUSH INLAND DUE TO CONTINUING SOUTHERLY FLOW ALOFT...THE COAST WILL SEE MARINE MOISTURE REFORM LATE TONIGHT FOR THE POSSIBILITY OF SOME FOG AND DRIZZLE LATE TONIGHT AND THU MORNING. WITH THE UPPER TROUGH REMAINING OFFSHORE KEEPING THE MID AND UPPER LEVEL FLOW OUT OF THE SOUTH...THU FRI AND SAT ALSO POSE THREATS FOR THUNDERSTORMS. A MORE SOUTHERLY DIRECTION TO THE FLOW THOUGH SUGGESTS THE BEST CHANCE FOR CONVECTION SHOULD BE OVER THE CASCADES...SO WILL LIMIT THE POPS TO THE OREGON CASCADES FOR NOW. FRI LOOKS LIKE THE BEST CHANCE OVERALL AFTER TODAY AS MODELS SHOW A WELL DEFINED VORT MAX LIFTING UP LATE FRI AND FRI NIGHT. TEMPS FOR THE NEXT FEW DAYS LIKELY TO REMAIN A LITTLE ABOVE NORMAL. .LONG TERM...MODELS...GFS AND ECMWF IN PARTICULAR...INDICATE A FINAL SHORTWAVE LIFTING OUT OF THE WEST COAST TROUGH SUN AND SUN NIGHT. DETAILS ON THIS WEAK SYSTEM ARE IN QUESTION...BUT GIVEN THE GENERAL PATTERN...WILL KEEP A THREAT FOR THUNDERSTORMS IN THE CLIMATOLOGICALLY MOST FAVORED AREAS...IE OREGON CASCADES. AFTER THAT...THERE IS GOOD CONFIDENCE IN THE MODELS IN DIGGING THE NORTHERN STREAM TROUGH DOWN OVER THE PACIFIC NW...BRINGING COOLER TEMPS AND MORE CLOUDS FOR THE FIRST HALF OF THE WEEK. WILL ADD IN A SMALL CHANCE FOR SOME LIGHT RAIN OR DRIZZLE TO THE NORTH COASTAL AS MODELS SHOW A RELATIVELY SHARP TROUGH WITH A SERIES OF SHORTWAVES MOVING THROUGH. && .AVIATION...WIDESPREAD VFR CONDITIONS THIS AFTERNOON WILL CONTINUE THIS EVENING. A MIX MVFR AND IFR CONDITIONS WILL RETURN TO THE COAST TONIGHT AND CONTINUE THROUGH THE MORNING...AND THESE CONDITIONS WILL PUSH FURTHER INLAND BY TOMORROW MORNING THAN TODAY. EXPECT MVFR/IFR ALONG THE COAST AFTER 06Z AND INLAND TO PARTS OF THE WILLAMETTE VALLY BY 10Z. LOOK FOR MVFR CUMULONIMBUS DEVELOPMENT THIS AFTERNOON AND MOVING NORTH THROUGH THE EVENING AND NIGHT UP THE CASCADES AND AREAS WEST...INCLUDING MUCH OF THE WILLAMETTE RIVER VALLEY. ISOLATED THUNDERSTORM DEVELOPMENT IS POSSIBLE IN THESE AREAS THROUGH TONIGHT. KPDX AND APPROACHES...VFR CONDITIONS AND LIGHT WINDS WILL CONTINUE THROUGH THIS EVENING. CUMULONIMBUS ARE POSSIBLE AFTER 00Z... ESPECIALLY OVER EASTERN APPROACHES. BROWN && .MARINE...HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE NE PACIFIC TONIGHT...ALLOWING NORTHERLY FLOW TO BECOME ESTABLISHED OVER THE WATERS THROUGH THE REST OF THE WEEK. AS THE HIGH BECOMES STRONGER LATER THIS WEEK...EXPECT GUSTY AFTERNOON AND EARLY EVENING WINDS EACH DAY...ESPECIALLY ON FRI INTO THE WEEKEND. A PERSISTENT NW SWELL WILL KEEP SEAS AROUND 5 TO 6 FT THROUGH THE END OF THE WEEK. JFP/BROWN && .PQR WATCHES/WARNINGS/ADVISORIES... OR...NONE. WA...NONE. PZ...NONE. && MORE WEATHER INFORMATION ONLINE AT... HTTP://WEATHER.GOV/PORTLAND THIS DISCUSSION IS FOR NORTHWEST OREGON AND SOUTHWEST WASHINGTON FROM THE CASCADE CREST TO 60 NAUTICAL MILES OFFSHORE.
