The episode as NWS OTX wrote it up.
A deep low pressure system tracked east across Vancouver Island and southern British Columbia. This resulted in damaging southwest winds over North Central Idaho, the Idaho Palouse, and the Lewiston area. Numerous power outages and fallen trees occurred in these areas. Several trees landed on power lines, vehicles, and homes. In North Idaho, Hauser Lake was hit hard by falling trees. Several mobile homes received extensive damage after trees fell on it, with three people injured. A marina on Lake Pend Oreille's Garfield Bay was also badly damaged. Hayden was also hit hard with several downed power poles and transmission lines. In the Central Panhandle Mountains, a Cessna 182 airplane was flipped over by the strong winds in Smeltzerville, just west of Kellogg. Wind gusts from this wind storm include: Northern Idaho Panhandle: Hauser Lake - estimated 75 MPH gusts; Coeur D'Alene area: Hayden - estimated 75 MPH gusts; Idaho Palouse: Moscow - 88 MPH gust; Central Panhandle Mountains: 10 E Kellogg - 70 MPH gust; Lewiston area: 8 N Lewiston - 59 MPH gust.
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 Spokane, WA wrote its last area forecast discussion before the first event at Dec 14, 9:35 PM PST, 1 hour 55 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
935 PM PST THU DEC 14 2006
.SYNOPSIS...A VERY STRONG STORM WILL TRACK THROUGH THE REGION
TONIGHT AND FRIDAY. POTENTIALLY DAMAGING WINDS AND SIGNIFICANT
AMOUNTS OF PRECIPITATION WILL ACCOMPANY THIS STORM. COLDER AIR WILL
MOVE INTO THE AREA FOR WEEKEND.
&&
.DISCUSSION...
REST OF TONIGHT...BACK EDGE OF FRONTAL PRECIPITATION SHIELD IS
CRAWLING ACROSS THE CASCADES AT 900 PM THIS EVENING. UPSTREAM
OBSERVATIONS SUGGEST THIS IS ALSO THE WIND SHIFT LINE. GIVEN THIS
BACK EDGE PASSAGE AND A MORE DOWNSLOPE COMPONENT TO THE LOW AND
MID LEVEL FLOW BEHIND IT...WOULD EXPECT A DRAMATIC TAPERING OFF OF
CURRENT STEADY SNOW INTO SHOWERS. THUS WILL END HEAVY SNOW
WARNINGS FOR THE CASCADES AND LEE ZONES AS PLANNED AT 1000
PM...WHILE NORTHEAST MOUNTAINS AND IDAHO PANHANDLE WSW WILL REMAIN VALID.
THIS WILL REQUIRE A HOUSEKEEPING ZONE UPDATE FOR HEADLINE REMOVAL.
OTHERWISE...NO COMPELLING REASON TO MESS WITH CURRENT FORECAST
PRECIPITATION FIELD OR WORDING CONCERNING WIND THREAT AS FRONT
PASSES TONIGHT. LATEST SATELLITE AND RADAR EXTRAPOLATION AS WELL
AS 00Z HI RES MODEL RUNS STILL SUGGEST A FROPA THROUGH WENATCHEE
AND MOSES LAKE AROUND 10 PM...THROUGH SPOKANE AROUND 11 PM TO
MIDNIGHT...AND PULLMAN-LC VALLEY 1-2 AM.
CURRENT RADAR WIND PROFILE INDICATES 55 KNOTS AT
4000 MSL AND 75 KNOTS AT 5000 FEET MSL OVER SPOKANE. MUCH OF THIS
ENERGY JUST OFF THE SURFACE WILL BE AVAILABLE FOR MIXING DOWN TO
THE SURFACE IN THE FRONTAL TRANSITION PERIOD.
THIS FROPA IS WHEN THE STRONG WIND THREAT WILL MATERIALIZE AS VERY
STRONG WINDS JUST OFF THE SURFACE HAPHAZARDLY
MIX DOWN TO THE EARTH AS SCATTERED 50 TO 70 MPH WIND
GUSTS...GREATEST THREAT OVER HIGHER TERRAIN...FOR A FEW HOUR
PERIOD DURING THE PRE-DAWN HOURS...AND THEN SETTLE DOWN INTO A
MORE-OR-LESS STEADY 30 TO 40 MPH SUSTAINED SOUTHWEST WIND WITH
LOCAL HIGHER GUSTS FROM TIME TO TIME AFTER DAWN AND THROUGH THE
MORNING HOURS.
EXPECTED LOW TEMPERATURES HAVE LIKELY ALREADY BEEN REACHED AND A
GENERAL STEADY OR SLIGHTLY RISING TREND IS EXPECTED THROUGH THE
REST OF THE NIGHT. WITH THE FLUID AND WELL MIXED SITUATION IT
WOULD BE FRUITLESS TO TRY TO REFINE THESE EXPECTED LOWS ANY
BETTER THAN THE GENERAL RANGE REFLECTED IN THE ZONE WORDING.
MINOR UPDATE TO STATE FORECAST TO REMOVE HEADLINES AT 1000 PM.
&&
.AVIATION...STRONG FRONTAL PASSAGE WILL BRING WIDESPREAD SURFACE
WINDS 40 KNOTS WITH GUSTS TO 50KTS OVER MOST OF THE REGION FROM 06Z
TO 18Z FRIDAY. MAINLY VFR CEILINGS AND VISIBILITIES EXPECTED OVER
THE COLUMBIA BASIN IN POST FRONTAL AIR MASS...WITH CONTINUING
MOUNTAIN OBSCURATIONS IN CLOUDS AND PRECIPITATION OVER THE IDAHO
PANHANDLE AND MOUTNAINS NORTH OF THE COLUMBIA BASIN THROUGH 06Z
SATURDAY.
