The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pendleton, OR wrote its last area forecast discussion before the first event at Aug 31, 9:54 PM PST, 2 hours 6 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PENDLETON OR 1054 PM PDT MON AUG 31 2015 UPDATED AVIATION DISCUSSION .SHORT TERM...TONIGHT THROUGH WEDNESDAY AFTERNOON...SATELLITE WATER VAPOR IMAGERY LOOP SHOWS A LONG WAVE TROUGH CENTERED ALONG 130W WITH A SERIES OF DISTURBANCES MOVING THROUGH THE LONG WAVE MID/UPPER LEVEL CYCLONIC CIRCULATION ASSOCIATED WITH THE LONG WAVE TROUGH. THE FIRST ONE MOVING THROUGH SOUTHERN BC IS DRAGGING MID AND HIGH CLOUDS ACROSS THE CWA THIS EVENING. ANOTHER ONE IS POISED TO ROUND THE BASE OF THE LONG WAVE TROUGH NEAR 131W AND HAS A DRIER AIR MASS ASSOCIATED WITH IT, AND YET ANOTHER ONE, THE STRONGEST BY FAR, NEAR 57N/141W IN THE EASTERN GULF OF ALASKA. THE LAST DISTURBANCE WILL DROP DOWN THE WESTERN FLANK OF THE LONG WAVE TROUGH OVER THE NEXT 36 HOURS, THUS DIGGING THE LONG WAVE TROUGH FARTHER SOUTH AND ALLOWING WEAK DYNAMIC LIFT TO ENTER THE FORECAST AREA ON WEDNESDAY IN COMBINATION WITH OROGRAPHIC LIFT OVER THE HIGHER MOUNTAINS FOR A CHANCE OF SHOWERS DURING THE DAY ON WEDNESDAY IN THE BLUE MOUNTAINS AND ALONG THE EAST SLOPES OF THE CASCADES. DRY CONDITIONS WILL PERSIST ELSEWHERE FOR TONIGHT THROUGH WEDNESDAY AFTERNOON. POLAN .AVIATION...06Z TAFS...VFR CONDITIONS WILL OCCUR WITH DRY WESTERLY FLOW ALOFT AND ONLY SCT-BKN200 CLOUDS AND LIGHT SFC WINDS OVERNIGHT. SKIES WILL CLEAR BY MIDDAY ON TUESDAY FOLLOWED BY SCT200-250 LATE IN THE AFTERNOON. WINDS WILL BE VERY LIGHT FOR REMAINDER OF TONIGHT AT KRDM AND KBDN WITH WINDS AROUND 10 KTS AT KDLS. THE REST OF THE TAF SITES WILL HAVE DRAINAGE WINDS OF 5-10 KTS OVERNIGHT. WINDS INCREASE LATE TUESDAY MORNING, BECOMING 10-15 KTS WITH GUSTS TO AROUND 20 KTS BY 19Z AND THESE WINDS WILL CONTINUE THROUGH TUESDAY AFTERNOON, THEN SLOWLY DECREASING AFTER SUNSET. POLAN && .PREVIOUS DISCUSSION... /ISSUED 212 PM PDT MON AUG 31 2015/ SHORT TERM...TONIGHT THROUGH THURSDAY...A BROAD UPPER LEVEL TROUGH OVER THE PACIFIC NORTHWEST WITH A WESTERLY FLOW WILL KEEP MOST OF THE FORECAST AREA DRY EXCEPT FOR SOME SHOWERS ALONG THE CASCADE CREST THROUGH TUESDAY. THEN SOME ENERGY DROPPING INTO THE TROUGH WILL LEAD TO THE TROUGH DIGGING SOUTHWARD TUESDAY NIGHT AND WEDNESDAY. THIS WILL PUSH A COLD FRONT TROUGH THE FORECAST AREA WITH A BAND OF PRECIPITATION ASSOCIATED WITH IT TUESDAY NIGHT AND WEDNESDAY. THE PRECIPITATION IS LIKELY TO SKIP OVER THE LOWER ELEVATIONS BUT THE MOUNTAINS COULD END UP SEEING SOME LIGHT ACCUMULATIONS. BY THURSDAY THE UPPER LEVEL TROUGH IS SETTLING OVER THE REGION BUT THERE IS SOME MODEL UNCERTAINTY. HAVE INDICATED A TREND TOWARDS MORE SHOWER ACTIVITY THURSDAY BELIEVING THE INCREASED INSTABILITY ASSOCIATED WITH THE TROUGH WILL LEAD TO A BETTER CHANCE OF PRECIPITATION ACROSS MOST OF THE FORECAST AREA. HIGH TEMPERATURES WILL BEGIN TO COOL ON WEDNESDAY AND BY THURSDAY WILL BE 10 TO 15 DEGREES BELOW NORMAL. LONG TERM...THURSDAY NIGHT THROUGH MONDAY...ACTIVE WEATHER PATTERN THROUGH PERIOD AND MODELS NOT IN AGREEMENT BEGINNING SUNDAY. UPPER LEVEL LOW PRESSURE AREA TO DROP SOUTH FROM BC INTO PAC NW ON FRIDAY. THAT MUCH MODELS AGREE UPON. THIS WILL BRING UNSETTLED...COOLER...AND SHOWERY CONDITIONS INTO ALL AREAS FOR FRIDAY AND SATURDAY. ENOUGH INSTABILITY FOR THUNDERSTORMS FRIDAY. BY SUNDAY...GFS OPENS UPPER LOW INTO A WAVE AND EJECTS INTO IDAHO AND MONTANA...WHILE GFS/CANADIAN HAVE STRONG JET LEVEL WINDS DIVING SOUTH ON WEST SIDE OF LOW AND KEEPING IT ANCHORED OVER SOUTHERN OREGON FOR ABOUT 12-18 HOURS LONGER BEFORE MOVING EAST. SO WITH THIS IN MIND I HAVE KEPT CHANCE POPS GOING LONGER ACROSS EASTERN ZONES...ESPECIALLY WALLOWA COUNTY TO ACCOUNT FOR POSSIBLE WRAPAROUND MOISTURE AFTER LOW MOVES INTO ID/MT. IF EC/CANADIAN MODELS PROVE CORRECT...SIGNIFICANT PRECIPITATION COULD OCCUR. FOR NOW WILL JUST INCREASE POPS UNTIL MODELS COME INTO AGREEMENT. && .PRELIMINARY POINT TEMPS/POPS...
