What happened

The episode as NWS PDT wrote it up.

A warming and drying trend continues today as a ridge builds over the region. Temperatures will get warmer, winds will increase, and humidity levels will decrease. Weather for Wednesday will feature breezy, dry and unstable conditions. As the weekend approaches a trough is expected to bring cooler and more humid conditions.

|Many post fire surveys will be generated by a team of scientists. The BAER assessment team generates a Soil Burn Severity map by using satellite imagery which is then validated and adjusted by BAER team field surveys to assess watershed conditions and watershed response to the wildfire. The map identifies areas of soil burn severity by categories of low/unburned, moderate, and high which corresponds to a projected increase in watershed response.

The BAER team presents these findings and treatment recommendations to Agency Supervisors in an assessment report that identifies immediate and emergency stabilization actions needed to address potential post-fire risks to human life and safety, property, cultural-heritage and critical natural resources.

In most cases, only a portion of the burned area is actually treated. Severely burned areas, steep slopes, places where water run-off will be excessive, fragile slopes above homes, businesses, municipal water supplies, and other valuable facilities are focus areas and described in the BAER assessment report as values-at-risk. | |Type III Management team Joe Wyatt will work with the outgoing team to exchange crucial information, strategize and transfer key logistical needs today. Official transition to the new team will occur Wednesday morning at 6:00 AM.

Closures in effect to minimize risks to public safety: DNR - All DNR State Trust lands and recreation sites within the Glenwood Block are closed. Yakama Nation Nation lands are closed to the public, except enrolled members. Burned areas remain closed until further notice. USFS The Mount Adams Wilderness closure has been rescinded.

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.
