The episode as NWS OTX wrote it up.
A strong cold front passage brought about very windy conditions over the Idaho Palouse, Lewiston area, and Camas Prairie. Numerous power outages and down trees were reported during the storm. Eleven power poles were blown down near Potlach on Highway 95 closing the road. In Moscow, 15 to 20 vehicles were damaged by falling trees. Moscow, Potlach, Troy, and Genesee Schools were closed due to widespread power outages. Very isolated lightning strikes over the Lewiston area and Camas Prairie resulted this event entered as both a thunderstorm wind and high wind event. Lightning was more abundant on the Idaho Palouse but high winds also occurred prior to the front passage. Wind gusts from the storm in miles per hour include: 64 in Lewiston, 63 at Mission Creek RAWS, and 61 at Corral Creek RAWS. Estimated wind gusts of 85 miles per hour occurred on the Idaho Palouse.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
652 PM PST MON NOV 15 2010
.SYNOPSIS...
RAIN AND MOUNTAIN SNOW WILL BE LIKELY ACROSS ALL BUT THE DEEPER
BASIN TONIGHT...BEFORE DECREASING TUESDAY. THIS WILL BE DUE TO A
FAST MOVING BUT STRONG SYSTEM MOVING THROUGH THE REGION. WINDY
CONDITIONS WILL DEVELOP TONIGHT OVER MUCH OF EAST WASHINGTON...WITH
POTENTIALLY STRONG AND DAMAGING WINDS IN THE EAST SLOPES OF THE
CASCADES AND THE WATERVILLE PLATEAU. ACTIVE WEATHER WILL CONTINUE
THROUGH THE WEEK...INCLUDING MORE PRECIPITATION AROUND MID WEEK...WITH
POSSIBLE LOW ELEVATIONS SNOW THURSDAY...FOLLOWED BY A SIGNIFICANT
COOL DOWN OVER THE WEEKEND.
&&
.DISCUSSION...
UPDATE FOR THE EVENING HOURS...DRY SLOTTING IS EVIDENT ON WATER
VAPOR IMAGERY THAT HAS NOW WORKED WELL INLAND FROM THE PACIFIC AND
STRINGS THE U.S./CANADA BORDER FROM VANCOUVER ALL THE WAY TOWARD
THE IDAHO PANHANDLE. AS DRIER LAYER RH VALUES WORK INTO THE AREA
IN ASSOCIATION WITH THIS DRY SLOTTING...STRATIFORM RAINS SHOULD
END IN MOST LOCATIONS...SAVE FOR THE UPSLOPE AREAS OF THE IDAHO
PANHANDLE. HOWEVER...THE LULL IN THE ACTION IS LIKELY TO BE RATHER
SHORT-LIVED. THE UPPER LOW IS ALREADY COMING DOWN TOWARD THE
NORTHERN TIP OF VANCOUVER ISLAND...AND GFS 500 MB TEMPERATURES
FALL OVER THE NORTHWESTERN CWA ~8C BY 06Z FROM 00Z. THE MODEL
MANIFESTS THIS AS A RATHER DEEP LAYER OF CONDITIONAL INSTABILITY
IN VARIOUS LAYERS BETWEEN 850 MB AND 500 MB. AS A RESULT...AND
BECAUSE OF CONTINUED WESTERLY/SOUTHWESTERLY FLOW...SHOWERY
PRECIPITATION SHOULD AGAIN BLOSSOM OVER MOST OF THE AREA EXCEPT
THE COLUMBIA BASIN AND WENATCHEE AREAS OVERNIGHT.
AS FOR THE WIND HIGHLIGHTS...NOTHING HAS CHANGED AT THIS TIME. IT
STILL REMAINS HIGHLY QUESTIONABLE AS TO WHETHER THE STRONGEST
WINDS WILL FIND THEIR WAY TO THE SURFACE OVER OUR FORECAST AREA.
MODEL CROSS SECTIONS ACROSS THE CASCADES AROUND WENATCHEE
DEFINITELY SHOW A LOT OF MOMENTUM OFF THE SURFACE...HOWEVER A
CAPPING LAYER NEAR MOUNTAINTOP IS EITHER LACKING OR VERY WEAK
DEPENDING UPON THE MODEL SELECTED. IN ADDITION...MODEL SOUNDINGS
INDICATE SURFACE LAYER STABILITY MAY BE ENOUGH TO KEEP THE HIGHER
MOMENTUM OFF THE SURFACE ACROSS THE LOWER COLUMBIA BASIN AND EVEN
POSSIBLY WENATCHEE. HOWEVER...MODEL SOUNDINGS SUGGEST A VERY WINDY
NIGHT OVER THE WATERVILLE PLATEAU...AS WELL AS AROUND POMEROY AND
ON THE PALOUSE. TRENDS WILL LIKELY STILL NEED TO BE MONITORED
OVERNIGHT...BUT NO CHANGES IN THE HEADLINES ARE LIKELY TO BE
FORTHCOMING THIS EVENING. /FRIES

.AVIATION...
WATER VAPOR IMAGERY SHOWS THE STORM MOVING INTO THE PAC NW WITH A
FAIRLY POTENT COLD FRONT RAPIDLY MOVING INTO COASTAL WASHINGTON THIS
EVENING. PCPN BEING FELT ACROSS EXTREME EASTERN WA AND THE NORTHERN ID
PANHANDLE IS ALL PRE-FRONTAL IN THE WARM SECTOR OF THE STORM. THE
COLD FRONT WILL MOVE QUICKLY ACROSS WA LATER THIS EVENING...WHICH WILL
FORCE MORE SHOWERS IN EXTREME EASTERN WA AND THE PANHANDLE...BUT THE
BASIN SHOULD BE SHADOWED OUT WITH STRONG WESTERLY WINDS MOVING IN
BEHIND THE FRONT. MAIN ISSUES WITH THIS SYSTEM WILL BE MVFR CIGS AND
LOCAL MVFR VIS RESTRICTIONS AT THE EASTERN TAF SITES. HOWEVER...
GUSTY WSW WINDS WILL PICK UP AT ALL TAF SITES FROM EAST TO WEST AS
THE COLD FRONT PASSES AFTER 03Z. EXPECT WIND GUSTS IN THE 30-40 KT
RANGE DURING THE 06-12Z PERIOD EARLY THIS MORNING. LOW LEVEL WIND
SHEAR MAY BECOME AN ISSUE AS WELL WHEN THE FRONT MOVES
THROUGH...ESPECIALLY AT KEAT...KMWH...KPUW...AND KLWS TAF SITES. /SVH
