The episode as NWS PUB wrote it up.
A strong weather system generated widespread high winds over southern Colorado. The damaging winds began during the last morning across the San Luis Valley and surrounding mountains. Wind gusts up to 75 mph occurred, with widespread tree damage and damage to fences and outbuildings. Around 2 p.m. MDT, a 69 kilovolt line between Antonito and Romeo, in the southern San Luis Valley, was taken down, and nearly 3000 people were without power for a time. The high winds also started a wildfire at the Great Sand Dunes early in the afternoon. Farther east, the most extensive damage occurred in the Wet Mountains in Custer County. Forest Road 369 was closed due to a vast blow down of mature pine and spruce trees. Hundreds of trees, some 100 feet tall and 200 years old, were brought down in a 4-mile swath. Other minor damage occurred throughout the southeast plains into the early evening. Another secondary surge of high winds occurred in the Pikes Peak Region after 3 a.m. MDT. A tree fell on a business, and caused extensive damage to the air conditioning unit on the roof.

NWS Pueblo, CO wrote its last area forecast discussion before the first event at Jun 6, 3:34 AM MST, 6 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 434 AM MDT WED JUN 6 2007 .SHORT TERM... (TODAY AND TONIGHT) MAIN STORY TODAY WILL BE THE WINDS. UNSEASONABLY STRONG UPPER LOW OVER THE PACIFIC NW AND NORTHERN GREAT BASIN WILL BE EJECTING TO THE EAST ACROSS WY AND INTO THE DAKOTAS BY TONIGHT DRAGGING A BORA TYPE COLD FRONT ACROSS THE AREA DURING THE AFTN. ASSOCIATED 120+ KT UPPER JET CORE WILL TRANSLATE ACROSS THE FORECAST AREA DURING THE AFTERNOON AND EARLY EVENING. SFC LEE TROF ALREADY DEEPENING IN RESPONSE TO APPROACHING SYSTEM...AND BOTH GFS/NAM SHOW IMPRESSIVE SFC PRESSURE GRADIENT DEVELOPING BY AFTN ACROSS EASTERN CO AS SFC TROF CONTINUES TO DEEPEN. NAM12 MODEL SOUNDING SHOWING A DEEP MIXED LAYER WITH 35 TO 40 KTS OF WIND ACROSS THE SE PLAINS...WITH THE AXIS OF STRONGEST WINDS ALONG THE SOUTHERN BORDER AREAS. WINDS MIX DOWN FAIRLY EARLY THIS MORNING...WITH KPUB PROBABLY THE LAST TO SEE THE STRONG WINDS SPREADING IN BY LATE MORNING/EARLY AFTN. OVERALL...LOOKS LIKE A DECENT SET UP FOR HIGH WINDS DUE TO DEEP MIXING...WITH SUSTAINED WINDS LIKELY MEETING THE CRITERIA OF 40 MPH ACROSS THE PLAINS...AND 50 MPH ACROSS THE MOUNTAINS. THINK HIGH WIND GUST CRITERIA (58 MPH PLAINS...70 MPH MOUNTAINS) MAY BE A BIT HARDER TO ACHIEVE ON A WIDESPREAD BASIS...WITH VALUES COMING IN AT OR JUST BELOW CRITERIA. REGARDLESS...WITH SUSTAINED VALUES SO HIGH...WILL GO AHEAD AND HOIST THE WARNING. HAVE ALSO ADDED THE EASTERN SAN JUAN MTS...AND THE HIGHER ELEVATIONS AND EASTERN SLOPES OF THE LA GARITAS...WHERE MODELS SHOWING MTN TOP SUSTAINED WINDS AROUND 50-60 KTS. WINDS LOOK A LITTLE WEAKER OVER THE CHAFFEE/LAKE COUNTY AREAS...IN PROXIMITY TO UPPER LOW...SO NO HIGH WIND HIGHLIGHTS NEEDED THERE. AS FOR PRECIPITATION CHANCES...AS UPPER TROF GLANCES BY TO THE NORTH...MOISTURE INCREASES AND LAPSE RATES STEEPEN AS UPPER LEVEL COLD POOL GLANCES BY. THIS WILL BRING A ROUND OF SHOWERS AND THUNDERSTORMS TO THE MOUNTAINS ALONG AND WEST OF THE CONTINENTAL DIVIDE THIS AFTERNOON THROUGH TONIGHT. RAIN/SNOW LEVELS WILL INITIALLY START OUT RATHER HIGH...BUT COLD AIR ADVECTION BEHIND THE FRONT WHICH MOVES THROUGH THIS AFTN...SHOULD QUICKLY DROP SNOW LEVELS TO AROUND 9000 FEET THROUGH THE EVENING. NAM12 SUGGESTS UP TO 4 INCHES OF SNOW POSSIBLE FOR THE HIGHER ELEVATIONS OF THE SAWATCH AND MOSQUITO RANGES BY EARLY THURS MORNING...AND COMBINED WITH HEALTHY WEST WINDS...SOME BLOWING AND DRIFTING WILL OCCUR. LATER SHIFTS MAY NEED TO MONITOR HIGHER ELEVATION ZONES OF CHAFFEE AND LAKE COUNTIES FOR POSSIBLE SNOW AND BLOWING SNOW ADVISORIES FOR TONIGHT. EVEN THOUGH SNOW AMOUNTS ARE BELOW THRESHOLD...THIS IS A RATHER LATE SEASON EVENT...AND MAY WARRANT A HIGHLIGHT IF 12Z MODEL RUNS CONTINUE TO INDICATE HEALTHY SNOW AMOUNTS. FARTHER SOUTH...MOISTURE GLANCES BY THE EASTERN SAN JUANS AND LA GARITA MOUNTAINS...SO NOT EXPECTING MUCH HERE. SAN LUIS VALLEY...EASTERN MOUNTAINS...AND SOUTHEAST PLAINS SHOULD STAY LARGELY DRY...THOUGH A STRAY SHOWER WOULDN/T BE OUT OF THE REALM OF POSSIBILITY FOR THE PIKES PEAK AREA AND NORTHERN FREMONT COUNTY. THIS MAY ACTUALLY HELP BRING DOWN STRONGER WIND GUSTS THAN PRODUCE MUCH IN THE WAY OF PRECIPITATION. WINDS WILL DIMINISH THROUGH THE EVENING HOURS...SO WILL END THE HIGH WIND WARNING AT 03Z. HOWEVER...INTERESTING SET UP FOR POTENTIAL MOUNTAIN WAVE EVENT BEGINS AFTER 06Z FOR THE PIKES PEAK REGION AND POINTS NORTHWARD. MODEL SOUNDINGS SHOW AN IMPRESSIVE MOUNTAIN TOP INVERSION...WITH SIGNIFICANT REVERSE SHEAR ABOVE. WINDS AT MTN TOP LAYER INCREASE TO AROUND 50-65 KTS BY 09Z...WITH A DUE WEST WIND COMPONENT...WHICH IS A FAVORABLE COMPONENT TO PRODUCE A MOUNTAIN WAVE INDUCED HIGH WIND EVENT FOR THE PIKES PEAK REGION. PARAMETERS LOOK EVEN MORE FAVORABLE TO THE NORTH OF THE FORECAST AREA...ACROSS THE FRONT RANGE. IN FACT...THIS EVENT HAS SOME OF THE STRONGEST SIGNATURES IVE SEEN FOR A MTN WAVE EVENT IN THE NAM12 DATA. THUS...WILL HOIST A HIGH WIND WATCH FOR THE PIKES PEAK/TELLER COUNTY...AND EL PASO COUNTY FOR LATE TONIGHT WHICH WILL CONTINUE THROUGH TOMORROW MORNING. FARTHER SOUTH...MODEL SOUNDINGS SHOW MUCH MORE FORWARD SHEAR ALOFT...WHICH IS MORE CONDUCIVE FOR TRAPPED WAVES. -KT .LONG TERM... (THURSDAY THROUGH TUESDAY) MAIN CONCERN IS THE POTENTIAL FOR A HIGH WIND EVENT THRU THE MORNING HOURS THU FOR TELLER AND PORTIONS OF WRN EL PASO COUNTY. STRONG UPR LOW WL BE OVR THE DAKOTAS THU MORNING WITH A 100KT JET LYING OVR THE FORECAST AREA. A STRONG MT TOP STABLE LAYER IS FORECAST TO REMAIN IN PLACE THU MORNING...WITH MT TOP WINDS AROUND 70 KTS...AND A CRITICAL LAYER ABOVE. 00Z AND 06Z NAM BOTH SHOWED STRONG BL WINDS ALONG THE RAMPART RANGE...WITH WINDS OF AROUND 70 KTS AT 12Z THU. HIGH WIND WATCH WL RUN THRU THU MORNING FOR TELLER AND EL PASO COUNTIES. BY AFTERNOON IT LOOKS LIKE THE WINDS SHOULD DECREASE SOME...BUT IT WL STILL BE BREEZY TO WINDY. SOME SCATTERED SHOWERS SHOULD CONTINUE IN PORTIONS OF THE CENTRAL MTS THRU THE DAY...AND COULD SEE SOME LIGHT ADDITIONAL SNOW ACCUMULATIONS IN THE MORNING. PREVIOUS MODEL RUNS KEPT ALL OTHER AREAS DRY THU...BUT THE 06Z RUN OF THE NAM IS PRINTING OUT SOME PCPN OVR SOME PORTIONS OF THE SERN PLAINS LATE THU AFTERNOON AND FOR THE EVENING WITH THE FRONTAL PASSAGE. WL LEAVE THE FORECAST DRY FOR NOW. THU NIGHT FREEZING TEMPS ARE LIKELY IN PORTIONS OF THE SAN LUIS VALLEY. IT IS TOO EARLY TO ISSUE A HIGHLIGHT FOR THIS. BY FRI THAT SYSTEM IS WELL TO THE EAST AND A WK SHRTWV RIDGE WL BE OVR THE AREA AND TEMPS WARM UP SOME MAINLY FOR THE WRN AREAS. SHOULD HAVE DRY WEA THIS DAY. ON SATURDAY THE RIDGE WL STILL BE OVR THE AREA...BUT FOR THE AFTERNOON AND EVENING HOURS...A SHRTWV TROF IS FORECAST TO MOVE OVR NERN NM AND THE MODELS SHOW SOME CONVECTION DEVELOPING OVR THE FAR SERN PLAINS...WHICH COULD CONTINUE INTO THE LATE NIGHT. SUN THE WEAK RIDGE WL STILL BE OVR THE AREA...AND IT LOOKS TO BE A DRY AND EVEN WARMER DAY. MON AN UPR TROF WL MOVE THROUGH WY...FLATTENING THE RIDGE OVR OUR AREA. DRY AND WARM WRLY FLOW WL CONTINUE THRU TUES. HIGHS SUN-TUE OVR MUCH OF THE SOUTHEAST PLAINS WL BE IN THE UPR 80S AND LOWER 90S. && .AVIATION...WINDS WILL INCREASE ACROSS THE AREA BY 15Z...WITH SUSTAINED WINDS APPROACHING 30-35 KTS ACROSS THE TAF SITES BY 18Z. WINDS OVER THE HIGHER MOUNTAINS WILL REACH SUSTAINED SPEEDS OF AROUND 45-50 KTS BY THIS AFTERNOON AS A STRONG UPPER LEVEL JET CORE MOVES OVERHEAD. WIND GUSTS UP TO 50 KTS ACROSS THE LOWER ELEVATIONS...AND UP TO 60 KTS CAN BE EXPECTED ACROSS THE HIGHER ELEVATIONS. STRONG TURBULENCE EXPECTED ALONG THE LEE OF THE MOUNTAINS TODAY WITH LOCALIZED WIND SHEAR POSSIBLE...ESPECIALLY THIS MORNING. OVERNIGHT...PARAMETERS LOOK FAVORABLE FOR A MOUNTAIN WAVE HIGH WIND EVENT ACROSS THE PIKES PEAK REGION AND THE KCOS TAF SITE AFTER 06Z. WIND SHEAR ALONG THE LEE OF THE RAMPART RANGE WILL BE POSSIBLE AS WIND GUSTS IN EXCESS OF 60 MPH WILL BE POSSIBLE BY EARLY MORNING. && .PUB WATCHES/WARNINGS/ADVISORIES...
