Some mountain wave activity brought a few strong wind gusts down to the surface along the Sheridan Foothills.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS BYZ wrote it up.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
846 PM MDT SAT NOV 1 2014
.UPDATE...
MINOR UPDATES TO THE GOING FORECAST THIS EVENING. FRONT SIDE OF
THE PACIFIC STORM SYSTEM IS PUSHING THROUGH THE AREA RIGHT NOW.
RADAR SHOWING A LINE OF SHOWERS FROM GREAT FALLS TO BILLINGS TO
GREYBULL MOVING NORTHEAST REFLECTING A DISTURBANCE ALOFT THAT IS
BEING SHOVED BY A JET STREAK. THE FURTHER EAST THIS PRECIPITATION
GETS THE LESS OF IT WILL HIT THE GROUND AND KEPT SOUTHEAST MONTANA
DRY WITH THIS FORECAST. DID BUMP THE BILLINGS AREA UP TO CHANCE
CATEGORY AS PRECIPITATION IS HOLDING TOGETHER JUST A BIT FURTHER
EAST THAN FORECAST ALLUDED TO. CAN'T RULE OUT AN ISOLATED
LIGHTNING STRIKE WITH THIS ACTIVITY FOR THE NEXT HOUR OR SO BUT
THESE WILL BE SO FEW THAT HAVE KEPT MENTION OF THUNDERSTORMS OUT
OF THE FORECAST THIS EVENING. BEST CHANCE FOR PRECIPITATION
TONIGHT WILL BE WEST OF A COLUMBUS TO RYEGATE LINE.
AS THIS CONVECTION SHIFTED THROUGH THE PARADISE VALLEY IT PRODUCED
WIND GUSTS TO 50 MPH IN THE LIVINGSTON AREA. MODELS INDICATE THE
POTENTIAL FOR GUSTS IN THE 30 TO 40 MPH RANGE FOR THE BEARTOOTH
FRONT RANGE AND SHERIDAN FOOTHILLS OVERNIGHT AS SOME MID LEVEL
WINDS GET DUCTED DOWN THE NORTH AND EAST SIDE OF THESE MOUNTAIN
RANGES AND PULLED BY DEEPENING SURFACE LOW PRESSURE ACROSS THE
PLAINS. FOR MOUNTAIN AREAS WINDS GUSTING TO 60 MPH ON EXPOSED WEST
FACING SLOPES SEEM REASONABLE. THESE STRONGER WINDS LOOK TO
DIMINISH DURING THE EARLY MORNING HOURS. AROUND SUNRISE THE MAIN
FRONTAL PUSH WILL MOVE INTO WESTERN AREAS RESULTING IN MORE GUSTY
WINDS OUT OF THE WEST TO NORTHWEST. INCREASED WINDS FOR THE
FOOTHILLS...ESPECIALLY AROUND SHERIDAN TONIGHT AND TWEAKED WINDS
IN OTHER AREAS A BIT. OTHERWISE FORECAST LOOKS IN PRETTY GOOD
SHAPE FOR TONIGHT. CHAMBERS
&&
.SHORT TERM...VALID FOR SUN AND MON...
MODELS CONTINUE TO BE IN FAIRLY GOOD AGREEMENT THROUGH THE
REMAINDER OF THE WEEKEND AS THE STORM SYSTEM TO AFFECT OUR
FORECAST AREA IS LOOKING LESS AND LESS OF AN IMPACT. CLOUDS THAT
WERE OVER THE CENTRAL AND WESTERN AREAS THIS MORNING HAVE MOVED
EAST ALLOWING FOR PLENTY OF AFTERNOON SUN FOR MOST LOCATIONS WHICH
HAS RESULTED IN TEMPERATURES QUICKLY WARMING INTO THE 60S. THE
UPPER LOW AND TROUGH CURRENTLY OVER THE GREAT BASIN AREA IS
PROVIDING FOR A SOUTHERLY FLOW ALOFT ACROSS OUR AREA. THE UPPER
LOW MOVING INTO SOUTHWEST IDAHO IS PROVIDING AMPLE LIFT AND
INSTABILITY FOR THUNDERSTORM DEVELOPMENT ACROSS EASTERN
IDAHO/WESTERN WYOMING AND NORTHERN UTAH. THIS ACTIVITY IS MOVING
STRAIGHT SOUTH TO NORTH AS THUNDERSTORMS ARE NOW JUST WEST AND
SOUTH OF THE BEARTOOTH/ABSAROKA MOUNTAINS SO CAN'T RULE OUT AN
ISOLATED THUNDERSTORM FOR OUR MOUNTAINS AND FOOTHILLS AREAS THIS
EVENING.
THE UPPER LOW WILL MOVE NORTHEAST TONIGHT AND IS EXPECTED TO BE
NORTH OF THE CANADIAN BORDER BY SUNDAY EVENING. AT THE SAME
TIME...A SURFACE LOW WILL DEVELOP OVER SOUTH CENTRAL MONTANA AND
IS PROGGED TO MOVE ACROSS SOUTHEAST MONTANA THIS EVENING INTO THE
WESTERN DAKOTAS BY SUNDAY MORNING. A COLD FRONT WILL SWEEP ACROSS
THE FORECAST AREA AS THE LOW MOVES EAST USHERING IN GUSTY WEST TO
NORTHWEST WINDS DURING THE DAY SUNDAY INTO SUNDAY NIGHT.
MODELS STILL PROG THE UPPER LOW TO MOVE NORTHEAST ACROSS NORTH
CENTRAL MONTANA REMAINING TO OUR WEST. AS A RESULT...THE BULK OF
THE PRECIP LOOKS TO STAY TO THE NORTH AND WEST OF OUR FORECAST
AREA. IN ADDITION...MODELS CONTINUE TO BACK OFF ON THE PRECIP EVEN
IN OUR WESTERN LOCATIONS. AS A RESULT...HAVE CONTINUED THE TREND
FROM THE PREVIOUS SHIFT IN LOWERING POPS EACH PERIOD. BEST CHANCES
FOR SHOWERS WILL CONTINUE TO BE OVER OUR SOUTHWEST MOUNTAINS AND
FOOTHILLS AND THE LOWER ELEVATIONS WEST OF BILLINGS LATE TONIGHT
AND THROUGH THE DAY SUNDAY. AS A RESULT OF A GUSTY WEST/NORTHWEST
BREEZE EXPECTED...DOWNSLOPE WILL BE A KEY FACTOR IN KEEPING
CONDITIONS MORE ON THE DRY SIDE FOR THE BILLINGS AREA. ALTHOUGH
ISOLATED TO SCATTERED SHOWERS ARE EXPECTED...PRECIP AMOUNTS
GENERALLY LOOK TO BE LIGHT FOR THE LOWER ELEVATIONS. IN
FACT...HAVE REMOVED POPS FOR MOST AREAS EAST OF BILLINGS SUNDAY
INTO MONDAY. THE ONLY ACCUMULATING SNOW LOOKS TO OCCUR ACROSS THE
BEARTOOTH/ABSAROKA MOUNTAINS WHERE 2 TO 4 INCHES WILL BE POSSIBLE.
HOWEVER...CAN'T RULE SOME SNOW SHOWER ACTIVITY FOR THE FOOTHILLS
AND LOWER ELEVATIONS BUT A RAIN/SNOW SHOWER MIX LOOKS TO BE THE
BEST BET AT BEST EARLY SUNDAY MORNING AND AGAIN SUNDAY NIGHT INTO
MONDAY MORNING.
THE STORM SYSTEM WILL MOVE WELL EAST OF THE STATE MONDAY ALLOWING
FOR A HIGH PRESSURE RIDGING TO SLOWLY BEGIN TO BUILD. TEMPERATURES
WILL BE MUCH COOLER SUNDAY AND MONDAY BUT ACTUALLY MORE AROUND
NORMAL FOR THE BEGINNING OF NOVEMBER. HOOLEY
.LONG TERM...VALID FOR TUE...WED...THU...FRI...SAT...
MEDIUM RANGE MODELS CONTINUE TO BE IN GOOD AGREEMENT THROUGH MUCH
OF THE EXTENDED FORECAST WITH JUST SOME MINOR TIMING DIFFERENCES
ON PROGRESSIVE SHORT WAVES THROUGH THE PERIOD. HOWEVER...BY
SATURDAY THE GFS IS STILL MORE AGGRESSIVE WITH A BACK DOOR COLD
FRONT THAN THE ECMWF. THIS HAS BEEN THE TREND OVER THE LAST
SEVERAL MODEL CYCLES SO THERE IS VERY LITTLE CHANGES FOR THIS
PACKAGE IN THE EXTENDED.
AFTER A SHORT WAVE MOVES ACROSS THE REGION TO OUR NORTH PRODUCING
A WINDY PERIOD FOR US TUESDAY...500MB HEIGHTS REBOUND THROUGH
THURSDAY LEADING TO MILD TEMPERATURES. ANOTHER SHORT WAVE IS
PROGGED TO MOVE ACROSS OUR REGION ON FRIDAY. SO COOLER CONDITIONS
AND SCATTERED SHOWERS SHOULD ENSUE. HOWEVER...THIS IS WHERE THE
GFS ALLOWS MUCH COOLER AIR TO INFILTRATE OUR REGION FROM THE
NORTHEAST AND THE ECMWF REMAINS MILD INTO THE WEEKEND. WE ARE
BASICALLY RELYING ON THE ECMWF DUE TO ITS BETTER OVERALL
PERFORMANCE SO FAR THIS AUTUMN. BT
&&
.AVIATION...
VFR CONDITIONS WILL PREVAIL TONIGHT. AREAS WEST OF ROSEBUD COUNTY
WILL SEE PERIODS OF LIGHT RAIN SHOWERS WHICH COULD PRODUCE LOCAL
MVFR CONDITIONS IN THE VICINITY OF AREA MOUNTAINS. WINDS WILL BE
STRONG IN AND NEAR AREA MOUNTAINS TONIGHT AND SOME STRONGER GUSTS
COULD PUSH DOWN THE FOOTHILLS AT TIMES TONIGHT...INCLUDING THE
KLVM AND KSHR TAF LOCATIONS. BY SUNRISE MORE WIDESPREAD AND
PERSISTENT GUSTY WINDS WILL MOVE INTO WESTERN AREAS BEHIND A COLD
FRONT. THESE WESTERLY WINDS GUSTING TO 35 KTS WILL SPREAD ACROSS
THE AREA DURING THE DAY SUNDAY. CHAMBERS
