The episode as NWS CYS wrote it up.

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 Cheyenne, WY wrote its last area forecast discussion before the first event at Feb 4, 9:48 PM MST, 3 hours 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 948 PM MST WED FEB 4 2015 .UPDATE... ISSUED AT 942 PM MST WED FEB 4 2015 TEMPERATURES ARE NOT RISING AS THE WINDS HAVE YET TO KICK IN. AS A RESULT...OVERNIGHT LOWS ARE SEVERAL DEGREES COLDER THAN WHAT WAS EXPECTED. WENT AHEAD AND UPDATED THE FORECAST FOR THESE TEMPERATURES AND UPDATES HAVE BEEN SENT. && .SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT) ISSUED AT 342 PM MST WED FEB 4 2015 SNOW IS WINDING DOWN ACROSS THE FORECAST AREA LATE THIS AFTERNOON. SOME LIGHT ACCUMULATIONS ARE POSSIBLE INTO THE SNOWY AND SIERRA MADRE RANGES THIS EVENING...OTHERWISE ONLY LOOKING FOR A FEW FLURRIES NEAR THE WYOMING/COLORADO BORDER. AS SNOW ENDS THE WINDS WILL INCREASE WITH SOME STRONGER WINDS DEVELOPING OVER THE WIND PRONE PORTIONS OF SOUTHEAST WYOMING TONIGHT. BIGGEST CONCERN IS THE POTENTIAL FOR BLOWING SNOW...ESPECIALLY IN THE WIND PRONE AREAS. WINDS WILL INCREASE TO 30 TO 40 MPH WITH GUSTS TO 50 IN THESE AREAS...SO THERE WILL BE BLOWING SNOW. SNOW AMOUNTS MAINLY IN THE 3 TO 6 INCH IN THESE AREAS SO TOUGH TO SAY JUST HOW MUCH VISIBILITIES WILL BE IMPACTED...BUT WILL NEED TO KEEP A CLOSE EYE ON THINGS THIS EVENING AS BLOWING SNOW HEADLINES MAY BE NEEDED AT SOME POINT. FORTUNATELY TEMPERATURES WILL SLOWLY RISE OVERNIGHT WITH TEMPERATURES RISING ABOVE FREEZING SHORTLY AFTER SUNRISE TOMORROW...BRINGING AN END TO ANY BLOWING SNOW. WARMING TREND BEGINS TOMORROW BUT SNOW WILL INHIBIT WARMING OVER MUCH OF THE FORECAST AREA. MOST SNOW WILL MELT BY THE END OF THE DAY WITH THE EXCEPTION OF THE HEAVIER BAND WHICH FELL FROM AROUND WHEATLAND TO TORRINGTON TO ALLIANCE. TEMPERATURES MAY AGAIN BE IMPACTED DUE TO SNOW ON THE GROUND FRIDAY AS WELL WITHIN THE HEAVIER BAND. NO CHANCES FOR PRECIPITATION THURSDAY OR FRIDAY. THE MAIN FORECAST CONCERN THE NEXT FEW DAYS WILL BE WIND SPEEDS...ESPECIALLY IN THE WIND PRONE AREAS. MODELS DISAGREE IN THE STRENGTH OF THE WINDS THURSDAY AND FRIDAY BUT BECOMING FAIRLY CONFIDENT STRONG WINDS WILL OCCUR FRIDAY NIGHT. .LONG TERM...(SATURDAY THROUGH WEDNESDAY) ISSUED AT 310 PM MST WED FEB 4 2015 MODELS IN REASONABLE AGREEMENT THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK...SHOWING ZONAL FLOW ALOFT THIS WEEKEND BECOMING MORE NORTHWESTERLY AS A RIDGE OF HIGH PRESSURE MOVES EAST OVER THE ROCKY MOUNTAINS BY MONDAY AFTERNOON. OTHER THAN LOCALLY STRONG WINDS...RELATIVELY QUIET WEATHER IS EXPECTED THIS WEEKEND WITH WARMER THAN NORMAL TEMPERATURES. HIGHS THIS WEEKEND WILL RANGE FROM THE MID 50S TO MID 60S OVER THE HIGH PLAINS...WITH MID 40S TO MID 50S WEST OF THE LARAMIE RANGE. A FEW LOCATIONS ACROSS WESTERN NEBRASKA MAY REACH 70 SATURDAY AFTERNOON BEFORE A WEAK PACIFIC COLD FRONT MOVES EAST ACROSS THE FORECAST AREA SATURDAY NIGHT. THIS FRONT WILL BRING SOME COOLER AIR TO THE REGION ON SUNDAY...BUT HIGHS WELL ABOVE NORMAL ARE STILL EXPECTED. MODELS INDICATE SOME LIGHT TO MODERATE SNOW FOR THE MOUNTAINS SATURDAY NIGHT THROUGH SUNDAY...WITH LIGHT ACCUMULATIONS POSSIBLE. FOR THE VALLEYS AND HIGH PLAINS...PRECIP WILL BE MINIMAL DUE TO DOWNSLOPE FLOW BUT SOME RAIN/SNOW MIX IS POSSIBLE DUE TO DAYTIME CONVECTION ON SUNDAY. TEMPERATURES WILL RISE ONCE AGAIN ON MONDAY AS THE UPPER LEVEL RIDGE AXIS MOVES ACROSS THE AREA. MODELS INDICATE THE NEXT UPPER LEVEL TROUGH AND ASSOCIATED COLD FRONT APPROACHING THE AREA ON TUESDAY. THIS IS WHERE MODELS BEGIN TO LOSE CONSISTENCY WITH THE ECMWF SHOWING FROPA AS EARLY AS TUESDAY MORNING WITH THE GFS 12 TO 18 HOURS LATER WITH THE FRONTAL PASSAGE INTO TUESDAY NIGHT. BOTH MODELS INDICATE A CLOSED LOW FORMING NEAR THE FOUR CORNERS REGION. THE POSITION OF THIS SYSTEM WILL BE KEY FOR THE EXTENDED PORTION OF THE FORECAST FOR WEDNESDAY AND POSSIBLY NEXT THURSDAY. FOR NOW...KEPT POP BETWEEN 15 TO 25 PERCENT AND LIGHT SNOW ACROSS THE AREA LATE TUESDAY AND INTO WEDNESDAY. TRENDED MAX AND MIN TEMPERATURES CLOSER TO NORMAL AS WELL. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT) ISSUED AT 942 PM MST WED FEB 4 2015 LATEST HRRR HAS GOTTEN RID OF THE LOW CEILINGS IN AND AROUND KCYS. LOOKS LIKE WINDS SHOULD SOON BECOME MORE WESTERLY AND DOWNSLOPING...SO DO HAVE TO GO WITH WHAT THE HRRR IS SHOWING. ONE LAST BAND OF SNOW OUT BY KSNY SHOULD EXIT SOUTHEAST OVER THE NEXT HOUR OR SO. VFR AND WINDY FOR OUR SOUTHEAST WYOMING AIRPORTS THURSDAY.| && .FIRE WEATHER... ISSUED AT 311 AM MST WED FEB 4 2015 A ENERGETIC NORTHWEST FLOW ALOFT COMBINED WITH COLD TEMPERATURES... MOIST UPSLOPE WINDS AND A COLD FRONT ALONG THE FRONT RANGE WILL PRODUCE WIDESPREAD SNOWFALL THROUGH EARLY THIS AFTERNOON. THE SNOW WILL BE MODERATE TO HEAVY AT TIMES EARLY THIS MORNING IN A BAND FROM DOUGLAS TO TORRINGTON TO SCOTTSBLUFF AND ALLIANCE. GUSTY NORTHEAST WINDS WILL CREATE AREAS OF BLOWING SNOW EARLY THIS MORNING. THE SNOW WILL TAPER OFF BY THIS EVENING AND REMAIN OVER THE SNOWY AND SIERRA MADRES TONIGHT.
