The episode as NWS CYS wrote it up.
A vigorous Pacific low pressure system brought widespread heavy snowfall and northerly winds up to 50 mph as it moved across the central Rockies. Storm total snow accumulations up to two feet were observed across the western Nebraska Panhandle. The combination of falling snow and strong winds produced considerable drifting snow, which resulted in very low visibilities and snow packed roads. Numerous highways, including Interstate 80 from Sidney to the Wyoming border were closed.
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 Apr 8, 5:10 PM MST, 50 minutes earlier.

NATIONAL WEATHER SERVICE CHEYENNE WY
610 PM MDT MON APR 8 2013
.UPDATE...
ISSUED AT 609 PM MDT MON APR 8 2013
RAIN HAS BEEN CHANGING OVER TO SNOW OVER ALL BUT THE SOUTHERN
PANHANDLE EARLY THIS EVENING. OVER THE SOUTHERN PANHANDLE...STILL
SOME THUNDERSTORMS AND WARMER AIR AS OF 2345Z. SATELLITE CLOUD
TOPS WILL COOL OVER THE ENTIRE CWA THIS EVENING AND SURFACE
TEMPERATURES WILL ALSO CONTINUE TO SLOWLY COOL. THAT SHOULD ALLOW
FOR WIDESPREAD SNOW OVER THE ENTIRE CWA BY LATE EVENING. FORECAST
IS ON TRACK AND AN UPDATE WAS MADE TO LOWER THE SNOW LEVEL EARLY
THIS EVENING.
&&
.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT ISSUED AT 348 PM MDT MON APR 8 2013
SIGNIFICANT EARLY SPRING SNOWSTORM CONTINUES TO TAKE AIM ON THE
REGION FOR TONIGHT AND TUESDAY. EARLY AFTERNOON SATELLITE PIX
PLACE UPPER LOW CENTER OVER THE SW CORNER OF UTAH. SFC REFLECTION
HAS THE 989MB SFC LOW FURTHER EAST ALONG THE UTAH/ARIZONA
STATELINE. SFC FRONT EXTENDS NORTH FROM THIS SFC LOW THRU UTAH
BEFORE TURNING EAST NR THE I80 CORRIDOR ACROSS SOUTHERN WYOMING
AND THE SOUTHERN NEBRASKA PANHANDLE. CONVECTION CONTINUES TO
STRENGTHEN IN THE WARM SECTOR SOUTH OF THIS BOUNDARY WITHIN AN
AREA OF 500 J/KG OF SBCAPE BASED ON SPC MESOANALYSIS. CONVECTION
WILL CONTINUE TO EXPAND ACROSS LARAMIE COUNTY AND SOUTHERN
NEBRASKA PANHANDLE THROUGH THE EARLY EVENING HOURS. SUFFICIENT
DIRECTIONAL AND SPEED SHEAR COUPLED WITH MODEST INSTABILITY WOULD
SUGGEST THAT A FEW OF THESE THUNDERSTORMS MAY CONTAIN SMALL HAIL
AND GUSTY WINDS FOR THESE AREAS.
12Z MODELS CONTINUE TO SHOW AN IMPRESSIVE AREA OF SATURATED
ISENTROPIC ASCENT LIFTING NORTH ACROSS MOST OF THE CWA BEGINNING
TONIGHT AND CONTINUING INTO TUESDAY. H3 JET STRUCTURE WILL PLACE THE
CWFA BENEATH THE FAVORABLE LFQ AS THE JET STREAKS ROUNDS THE BASE OF
THE TROUGH LATER TONIGHT AS WELL. ALL THIS AS LLVL COLD AIR MASS
DEEPENS AND TURNS WINDS NORTHEASTERLY AS THE SFC LOW MOVES ACROSS
COLORADO TONIGHT AND DURING THE DAY ON TUESDAY. BUFKIT SOUNDINGS
SHOW STRONG OMEGA COLLOCATED WITH A COMPLETELY SATURATED AREA
WITHIN THE DENDRITIC GROWTH ZONE. SNOWFALL RATES WILL INCREASE
THROUGH THE EVENING HOURS AS SNOW LEVELS DESCEND THROUGH 5 KFT.
AFTER MIDNIGHT...SNOWFALL RATES MAY REACH 1 TO 2 INCHES PER HOURS
ACROSS THE AREA AS THE LOW PRESSURE LIFTS NORTHEAST THROUGH THE
CENTRAL ROCKIES. THE OTHER CONCERN IS THE POTENTIAL FOR A
FREEZING RAIN/SLEET MIX ACROSS PORTIONS OF THE SOUTHERN NEBRASKA
PANHANDLE. FORECAST RAOBS AT KSNY SHOW A 2C WARM NOSE BETWEEN
700-800MB OFF BOTH THE NAM AND GFS CENTERED AROUND 06Z. FOR THIS
REASON...EXPECT THAT AREAS OF THE SOUTHERN NEBRASKA PANHANDLE
SHOULD SEE SLIGHTLY TEMPERED SNOWFALL AMOUNTS. OF COURSE...THE
COMBINATION OF THIS WINTRY MIX ALONG WITH THE ANTICIPATION OF
COMPLETE TURN OVER TO SNOW ON TUESDAY AND MODERATE ACCUMULATIONS...
STILL THINK THAT A WINTER STORM WARNING WILL WORK OUT THERE. THESE
CONDITIONS WILL CONTINUE DURING THE DAY ON TUESDAY AS WELL WITH
WIDESPREAD SNOW CONTINUING. THE OTHER MAJOR FACTOR WILL BE THE
VERY STRONG SURFACE WINDS THAT WILL ACCOMPANY THE FALLING SNOW.
NORTHEAST WIND GUSTS IN EXCESS OF 40 MPH DEFINITELY A GOOD BET
TONIGHT AND DURING THE DAY ON TUESDAY. THIS WILL CONTRIBUTE TO
CONSIDERABLE BLOWING AND DRIFTING SNOW ALONG WITH NEAR WHITE-OUT
CONDITIONS LATE TONIGHT AND DURING THE DAY ON TUESDAY. WILL NEED
TO WATCH THIS AS BLIZZARD CONDITIONS WILL CERTAINLY BE A
POSSIBILITY.
AS FOR SNOW AMOUNTS...DID DECREASE THEM SLIGHTLY WITH GENERALLY 8
TO 14 INCHES ACROSS A LARGE PORTION OF THE FORECAST AREA WITH
LOCALLY HIGHER AMOUNTS POSSIBLE IN THE HIGHER TERRAIN AND NEAR THE
PINE RIDGE. AS MENTIONED EARLIER...AREAS OF THE SOUTHERN NEBRASKA
PANHANDLE MAY SEE SLIGHTLY LESSER AMOUNTS ESPECIALLY IF THE
FREEZING RAIN/SLEET MIX MATERIALIZES LATER TONIGHT. AS SUCH...
WOULD EXPECT GENERALLY 5 TO 10 INCHES ACROSS THAT AREA. A SOLID 6
TO 12 INCHES IS EXPECTED WEST OF THE LARAMIE RANGE WITH UP TO 2
FEET POSSIBLE IN THE SNOWY RANGE. AREAS AROUND SARATOGA WILL
LIKELY BE SHADOWED BY THE THE SNOWY RANGE GIVEN THE STRONG
NORTHEASTERLY FLOW AT THE SURFACE. WIDESPREAD PRECIPITATION WILL
KEEP HIGH TEMPERATURES SIGNIFICANTLY COLDER ON TUESDAY...WHERE
MOST PLACES WILL STRUGGLE TO CLIMB ABOVE THE TEENS.
.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT ISSUED AT 348 PM MDT MON APR 8 2013
MODELS CONTINUE TO SHOW THE UPPER TROUGH TO SLOWLY MOVE EAST TUESDAY
NIGHT THROUGH WEDNESDAY. SFC HIGH PRESSURE BUILDING SOUTH ACROSS THE
REGION WILL BRING CONTINUED COLD TEMPS TUESDAY NIGHT AND
WEDNESDAY...WITH PERIODS OF LIGHT TO MODERATE SNOW CONTINUING
THROUGH WEDNESDAY MORNING. THE MAIN FOCUS WILL REMAIN OVER THE
EASTERN PLAINS WHERE WRAPAROUND LOW AND MIDLEVEL MOISTURE WILL
LINGER. COULD SEE AN ADDITIONAL 1 TO 4 INCHES OF SNOW ACCUMULATION
THROUGH AROUND NOON ON WEDNESDAY ALONG AND EAST OF THE LARAMIE
RANGE. BLOWING SNOW WILL CONTINUE TO BE A CONCERN WITH GUSTY
NORTHWEST WINDS OF 20 TO 30 MPH AS WELL. THE STORM WILL SLOWLY SHIFT
EAST WEDNESDAY NIGHT WITH SNOW AND WIND ENDING. TEMPERATURES WILL
MODERATE SOME ON THURSDAY...BUT WILL LIKELY NOT WARM TOO MUCH DUE TO
THE FRESH SNOWPACK. ANOTHER CLIPPER SYSTEM WILL MOVE ACROSS THE
FORECAST AREA ON THURSDAY WITH INCREASING CHANCES MAINLY FOR
MOUNTAIN SNOW AND LOWER ELEVATION RAIN SHOWERS THROUGH THURSDAY
EVENING. NORTHWEST FLOW WILL REMAIN ALOFT AND WILL KEEP THE PATTERN
FAIRLY ACTIVE THROUGH THE WEEKEND WITH TEMPERATURES REBOUNDING BACK
NEAR NORMAL VALUES. IN PARTICULAR...SATURDAY NIGHT THROUGH SUNDAY
COULD SEE MORE WIDESPREAD RAIN AND HIGH ELEVATION SNOW SHOWERS
THROUGH THIS TIME AS A STRONGER JET AND COLD FRONT MOVE ACROSS THE
REGION.
&&
.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY AFTERNOON)
ISSUED AT 609 PM MDT MON APR 8 2013
CLOUD BASES WILL CONTINUE TO LOWER OVER THE CWA THIS EVENING. BY
LATE EVENING...WIDESPREAD IFR CEILINGS AND VISIBILITIES IN SNOW
WILL AFFECT THE CWA. THE LOW CONDITIONS WILL CONTINUE THROUGH
TUESDAY EVENING BEFORE GRADUALLY LIFTING TO MVFR AND FINALLY
VFR BY WEDNESDAY. THE MOUNTAINS WILL BE OBSCURED THROUGH EARLY
TUESDAY NIGHT. EARLY TONIGHT...AREAS OF SLEET AND FREEZING RAIN
MAY OCCUR OVER THE AREA FROM KAIA TO KSNY. ICING WILL BE A MAJOR
CONCERN EARLY TONIGHT.
NORTH TO NORTHEAST SURFACE WINDS WILL GUST AS HIGH AS 40 KNOTS
OVER MUCH OF THE CWA THROUGH TUESDAY. THOSE WINDS WILL PRODUCE
CONSIDERABLE BLOWING AND DRIFTING SNOW WHICH WILL FURTHER REDUCE
VISIBILITIES DURING THAT TIME.
&&
.FIRE WEATHER...
ISSUED AT 348 PM MDT MON APR 8 2013
NO FIRE WEATHER CONCERNS AS A SPRING SNOWSTORM PRODUCES ACCUMULATING
SNOW ACROSS THE DISTRICT TONIGHT THROUGH TUESDAY NIGHT. SNOWFALL
ACCUMULATIONS OF 8 TO 15 INCHES WILL BE COMMON ACROSS MUCH OF THE
REGION...WITH LOCALLY UP TO 2 FEET IN THE HIGHER ELEVATIONS. THE
COMBINATION OF VERY STRONG NORTHEASTERLY WINDS AND FALLING SNOW WILL
PRODUCE NEAR WHITE-OUT CONDITIONS AT TIMES. SNOW WILL WIND DOWN
TUESDAY NIGHT...GIVING WAY TO WARMING CONDITIONS THROUGH THE REST OF
THE WEEK.
