The episode as NWS GJT wrote it up.
A strong spring storm system moved across the Four Corners area and produced heavy snow and strong winds across many mountains of west central and southwest Colorado. Local wind gusts as high as 66 mph were clocked near Red Mountain Pass in the San Juan Mountains, while wind gusts of 20 to 35 mph were common throughout the central and southern mountains. Widespread snowfall amounts of 1 to 2 feet blanketed the area, and blowing and drifting snow was common. The Silverton Mountain Ski Area reported a total snowfall of 30 inches.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
240 PM MST TUE MAR 28 2006
.SHORT TERM (TONIGHT THROUGH WEDNESDAY)...
MOISTURE DEEPENING OVER THE SWRN PORTION OF OUR FORECAST AREA WITH
METAR SITES OCCASIONALLY REPORTING LIGHT RAIN. EARLIER...CDOT
INDICATED ENOUGH SNOWFALL FOR CHAIN LAWS OVER THE SWRN SAN JUAN
MOUNTAINS ON HIGHWAY 550. WITH PERIODS OF SNOW CONTINUING AND THE
OVERALL TREND EXPECTS INCREASING SNOW...ELECTED TO GO AHEAD AND
START THE WINTER STORM WARNING WITH THE MORNING UPDATE. MOISTURE
WILL CONTINUE TO STREAM NORTHWARD WITH THE CHANCE OF PCPN SPREADING
NORTHWARD TO NW COLORADO. BUT HIGHEST RAIN/SNOWFALL AMOUNTS WILL BE
OVER SWRN COLORADO WHERE PERSISTENT SOUTHERLY FLOW GIVES THE SAN JUAN
MOUNTAINS STEADY LIGHT RAIN/SNOW. WHAT/S INTERESTING...THE LATEST
NAM MODEL HAS BACKED OFF ON QPF AMOUNTS AND ONLY SHOW LIGHT AMOUNTS
THROUGH TONIGHT. BUT RADAR IMAGES AND SURFACE OBSERVATIONS INDICATE
THAT THE EARLIER AND WETTER NAM MODEL RUNS MAYBE RIGHT ON. WINTER
STORM WARNING FOR HEAVY SNOW OVER THE SAN JUAN MOUNTAINS...WITH SNOW
AND BLOWING SNOW ADVISORY FOR THE ERN UTAH MOUNTAINS APPEAR ON TRACK.
HAVE INCLUDED THE NWRN SAN JUAN MOUNTAINS (TELLURIDE) TO THE LIST OF
ADVISORIES.
COLD ADVECTION SPREADS ACROSS THE ENTIRE FORECAST AREA WEDNESDAY
EVENING AND PCPN BECOMES WIDESPREAD (EXCEPT FOR PORTIONS OF THE
YAMPA RIVER BASIN). EXPECT THAT THE LIST OF ADVISORIES TO
EXPAND...BUT WILL HOLD OFF FOR NOW BUT FORECAST LOW END SNOW
ADVISORY AMOUNTS IN THE GRIDS. IN ADDITION...THE SNOW LEVELS WILL
LOWER AND PLACES LIKE PAGOSA SPRINGS AND DURANGO WILL NEED TO BE
MONITORED FOR POSSIBLE ACCUMULATING SNOWFALL. LOWER VALLEYS COULD
SEE NONACCUMULATING WET SNOW.
THE NAM MODEL IS VERY QUICK IN DRYING THINGS OUT ON THURSDAY...EVEN
FOR NW COLORADO IN NORTHWEST FLOW. THIS MAY BE TOO QUICK AS CLOSED
CIRCULATING UPPER LOWS TEND TO BE SLOW (OR SLOWER THAN THE MODEL
INDICATES)...EVEN WITH UPSTREAM ENERGY BEHIND IT TO PUSH THE TROUGH
EAST. WILL CONTINUE WITH THE IDEA THAT SHOWERS WILL STILL BE
CONCENTRATED OVER NW COLORADO...BUT RAIN/SNOW THREAT DIMINISHES
FAIRLY QUICKLY OVER ERN UTAH AND SWRN COLORADO.
.LONG TERM (THURSDAY NIGHT THROUGH TUESDAY)...
RESIDUAL MOISTURE IN NW FLOW WILL KEEP A CHANCE OF SNOW AROUND FOR
THE NRN MTNS THU EVENING. DRY CONDITIONS EXPECTED ON FRI AS
TRANSITORY RIDGE SLIDES ACROSS THE AREA...THOUGH FAIR AMT OF HIGH
CLOUDINESS SHOWN AS FLOW BECOMES W-SW.
LITTLE CHANGE MADE TO THE FORECAST GRIDS SAT-TUE. GFS/ECMWF SIMILAR
FOR THE WEEKEND BUT THEN 12Z SOLUTIONS DIFFER BY TUE. BOTH BRING A
WEAK WAVE MOVING ACROSS THE FORECAST AREA SAT AFTN WHILE MOST OF THE
ENERGY IS CONCENTRATED ACROSS THE PACIFIC NW...CLOSER TO THE MAIN
LONG WAVE TROUGH OVER THE NERN PACIFIC. GFS SHIFTS THIS LONG WAVE
TROUGH INLAND EARLY NEXT WEEK...WITH A STRONGER SHORTWAVE MOVING
ACROSS ON TUE WITH A COLD FRONT AND BETTER CHANCE OF PRECIPITATION.
ECMWF...ON THE OTHER HAND...KEEPS THE TROUGH OFFSHORE WITH STILL SOME
RIDGING OVER ERN UT/WRN CO ON TUE.
