The episode as NWS BOU wrote it up.
Strong winds developed over portions of the Urban Corridor. In Fort Collins, strong winds downed a tree near a home daycare facility. No one was injured in the incident. At the CSU campus, a strong wind gust ripped apart a large party tent set up at the stadium. In addition, approximately 500 homes and businesses lost power for an hour or two when some power lines were downed. The wind was blamed for knocking over a semi-trailer on State Highway 287, about 3 miles north of Ted's Place. Strong winds were also reported south of Denver in Douglas County. Peak wind reports included: 70 mph (61 kts) at Franktown, 65 mph (56 kts) at Castle Rock and 61 mph (53 kts) at Sedalia.

NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Nov 3, 3:18 AM MST, 5 hours 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 318 AM MST THU NOV 3 2005 .SHORT TERM...RADAR SHOWING DIFFERENTLY CONFIGURED WIND SIGNATURE TONIGHT COMPARED TO 24 HOURS AGO. THE SIGNATURE IS FURTHER EAST IN BOULDER AND LARIMER COUNTIES THAN YESTERDAY. THE SIGNATURE IS ALSO SHOWING UP SOUTH OF I-70 IN CLEAR CREEK...PARK...SOUTHERN JEFFERSON ...EVEN SOUTHWESTERN DOUGLAS. THERE IS NO PRECIPITATION INDICATED ON THE RADAR AT THIS TIME. THERE IS SOME ON GRAND JUNCTIONS RADAR. MODELS HAVE A SOUTHWESTERLY JET MAX SLIDING EASTWARD ACROSS THE FORECAST AREA FROM MID DAY THROUGH THIS AFTERNOON. AFTER THAT A WEAK TROUGH AXIS MOVES ACROSS US BY 00Z THIS AFTERNOON...THEN INCREASING ZONAL FLOW IS PROGGED THROUGH 12Z FRIDAY MORNING. THE QG VERTICAL VELOCITY FIELDS HAVE SOME UPWARD MOVE AIR TODAY...THEN WEAK DOWNWARD IS PROGGED TONIGHT. THE LOW LEVEL PRESSURE AND WIND FIELDS SHOW A INSIGNIFICANT PRESSURE GRADIENT OVER THE FORECAST AREA TODAY AND TONIGHT. PERHAPS A BRIEF SHOT OF WEAK UPSLOPE FOR THE PLAINS LATER TONIGHT. MOISTURE WISE...CROSS SECTIONS FROM EITHER MODEL HAVE ONLY FAIR MOISTURE IN THE MOUNTAINS...AND ITS NOT VERY DEEP AS WELL. THE PLAINS HAVE LESS MOISTURE PROGGED AS WELL. FOR THE MOUNTAIN SNOW...THERE IS MINIMAL TO COLD AIR ADVECTION AT BEST TODAY AND TONIGHT. MOISTURE IS NOT IMPRESSIVE AS MENTIONED ABOVE. THE MOUNTAIN TOP FLOW DIRECTION IS PROGGED AT 250-260 DEGREES...NOT EVEN DUE WESTERLY. SPEEDS ARE NOT BAD HOWEVER. THE DIRECTION IS NOT GREAT FOR OROGRAPHIC ENHANCEMENT IN OUR MOUNTAINS. THE QPF GRIDS SHOW VERY LIMITED AMOUNTS OF PRECIPITATION TODAY...AND EVEN LESS TONIGHT. WILL BACK-OFF A BIT ON THE POPS IN THE MOUNTAINS. GET MORE IN LINE WITH SURROUNDING OFFICES AS WELL. POPS WILL BE 30-50% IN HIGH COUNTY AND MAY MENTION LOCAL ACCUMULATIONS UP HIGH. CONCERNING WIND THREAT...THE CURRENT MOUNTAIN TOP STABLE LAYER IS PROGGED TO LIFT A BIT AND LESS SOMEWHAT. THE LOW LEVEL GRADIENT IS NOT VERY STRONG AS WELL. NO HIGHLIGHTS FOR WIND. TEMPERATURES LOOK TO BE 3-6 C COOLER FOR HIGHS TODAY FORM YESTERDAYS. .LONG TERM...ONE WEAK DISTURBANCE WILL MOVE ACROSS AREA ON FRI IN FAIRLY STG ZONAL FLOW ALOFT AND WILL HAVE SOME WEAK QG ASCENT ASSOCIATED WITH IT. ONCE AGAIN JUST LIKE LAST NIGHT NAM AND GFS DIFFER ON AMOUNT OF MOISTURE THAT WILL AFFECT THE MTNS AS THE NAM IS MORE MOIST THAN THE GFS. FOR NOW WILL TREND WITH THE GFS AND HAVE POPS IN THE SCT CATEGORY. POSITION OF UPPER LEVEL JET COULD ENHANCE PCPN IN SOME AREAS DUE TO POSSIBLE CSI IF MOISTURE DEPTH IS SUFFICIENT ENOUGH. OVER LOWER ELEVATIONS IT WILL REMAIN DRY ALTHOUGH WILL SEE SOME MID AND HIGH CLOUDS MOVE ACROSS. 850-700 MB WILL COOL A FEW DEGREES ON FRI AS WELL WHICH WILL LEAD TO SLIGHTLY LOWER TEMPS OVER NERN CO. MEANWHILE WINDS ALOFT WILL BE RATHER STG WITH SOME HINT OF A MTN TOP INVERSION IN THE 700-600 MB LAYER HOWEVER THERE MAY BE TOO MUCH SHEAR FOR WIDESPREAD HIGH WINDS IN THE HIGHER FOOTHILLS AND MTN AREAS. FOR FRI NIGHT INTO SAT FLOW ALOFT WILL BECOME MORE NWLY AS ANOTHER WEAK DISTURBANCE MOVES ACROSS WY. CROSS-SECTIONS SHOW SOME MOISTURE LINGERING IN THE MTNS HOWEVER BEST LAPSE RATES ARE FCST OVER WY. THUS WILL ONLY MENTION SCT POPS IN THE MTNS FOR FRI NIGHT INTO SAT. OVER LOWER ELEVATIONS IT WILL REMAIN DRY WITH TEMPS COOLING ANOTHER 5 DEGREES OR SO OVER NERN CO WITH AFTN HIGHS GENRALLY IN THE 50S FOR SAT. MTN TOP INVERSION WILL BE PRESENT ON SAT AND WIND FIELDS HAVE LESS SHEAR ALOFT SO COULD SEE A BETTER CHC OF STRONGER WINDS AFFECTING AREAS ON AND NEAR THE FOOTHILLS LATE FRI NIGHT INTO SAT. BY SUN AND MON AN UPPER LEVEL RIDGE WILL BUILD OVER THE AREA WITH A DOWNSLOPE LOW LEVEL FLOW EAST OF THE MTNS. MOISTURE IS FCST TO DECREASE QUITE A BIT IN THE MTNS SAT NIGHT INTO SUN SO PCPN THREAT SHOULD END. AT LOWER ELEVATIONS LATEST GFS SHOWS TEMPS IN THE 850-700 MB LAYER WARMING 5 TO 6 DEGREES ON SUN AND ANOTHER DEGREE OR SO ON MON WHICH WOULD ALLOW FOR AFTN HIGHS TO RISE WELL INTO THE 60S AND POSSIBLY INTO THE 70S. ON TUE GFS QUICKLY MOVES AN UPPER LEVEL TROUGH ACROSS THE AREA WITH A COLD FRONT MOVING INTO NERN CO TUE NIGHT INTO WED MORNING. THIS COULD LEAD TO A CHC OF SNOW IN THE MTNS TUE INTO TUE NIGHT WITH POSSIBLY A CHANCE OF SOME PCPN OVER NERN CO TUE NIGHT INTO WED MORNING ALONG WITH COOLER TEMPS. .BOU WATCHES/WARNINGS/ADVISORIES...NONE. && RJK/RPK
