Another cold Pacific storm system moved through the State of Utah at the end of November, bringing heavy snowfall to much of the state.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS SLC 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1006 AM MST SAT NOV 27 2010
.SYNOPSIS...A PACIFIC STORM SYSTEM WILL CROSS THE REGION TONIGHT
THROUGH EARLY MONDAY. HIGH PRESSURE WILL RETURN FOR THE MIDDLE PART
OF THE WEEK.
&&
.DISCUSSION...THE UPPER TROF CONTINUES TO MOVE INTO THE WESTERN
STATES THIS MORNING WITH INCREASING SOUTHWEST FLOW ALOFT OVER UT.
THE SOUTH WINDS HAVE STARTED TO SURFACE IN THE MORE ELEVATED AREAS
OF THE WESTERN UT VALLEYS WHILE SHALLOW COLD AIR REMAINS IN PLACE AT
MOST VALLEY BOTTOMS. THIS COLD AIR WILL CONTINUE TO ERODE TODAY INTO
TONIGHT AS THE UPPER TROF APPROACHES AND THE SURFACE PRESSURES
CONTINUE TO FALL.
THE SURFACE FRONT WITH THIS UPPER TROF APPEARS TO BE WEAK AND
SOMEWHAT DISORGANIZED BUT THE POST FRONTAL SURFACE GRADIENT IS
FORECAST TO BE FAIRLY STRONG SO THERE WILL BE SOME FORCING ALONG THE
SURFACE BOUNDARY. SOME PREFRONTAL PRECIP IS POSSIBLE TONIGHT NORTH
AND WEST OF SLC IN A WEAK WARM FRONTAL ENVIRONMENT BUT IT APPEARS
MOST OF THE PRECIP ASSOCIATED WITH THIS SYSTEM WILL BE BEHIND THE
FRONT WITH PRECIP LINGERING INTO MIDDAY MON IN NORTHWEST FLOW
UPSLOPE AREAS.
I THINK THE STORM TOTAL ACCUMULATION IN THE VALLEYS ALONG I-15 COULD
EXCEED 6 INCHES IN SOME AREAS BUT PRECIP WILL BE STRUNG OUT OVER A
24-36 HOUR PERIOD WITH SUB-WARNING AMOUNTS EVEN DURING THE DAY SUN.
THIS PLUS AN ILL DEFINED SURFACE FRONT AND A SHOWERY NATURE TO THE
PRECIP AFTER SUN LEADS ME TO LEAN MORE TOWARDS ISSUING A WINTER
WEATHER ADVISORY VS A WARNING FOR THESE ZONES.
WARNING LEVEL AMOUNTS SHOULD OCCUR IN THE MTNS FROM THIS SYSTEM
ALTHO ACCUMULATIONS WILL BE VERY DEPENDENT ON OROGRAPHICS.
PRECIP TYPE SHOULD NOT BE AN ISSUE WITH THE AIRMASS ALOFT COOLING
ENOUGH BEFORE PRECIP STARTS TO PRECLUDE FREEZING RAIN IN THE VALLEYS
WITH TRAPPED COLD AIR. THERE SHOULD ALSO BE ENOUGH MIXING IN THE ST
GEORGE AREA TO RESULT IN RAIN THERE OR AT WORST WET SNOW WITH LITTLE
ACCUMULATION.
PRECIP SHOULD END IN THE VALLEYS BY MIDDAY MON AND ACROSS THE MTNS
BY LATE MON WITH RIDGING BUILDING IN FOR TUE.
NO UPDATES PLANNED AT THIS TIME.
&&
.AVIATION...WHILE SURFACE WINDS AT THE SLC TERMINAL ARE
NORTHWESTERLY AS OF 16Z...WINDS MAY CONTINUE TO BE LIGHT AND
VARIABLE AT TIMES THROUGH 19Z...BEFORE INCREASING FROM THE
NORTHWEST BETWEEN 19 AND 21Z. CEILINGS WILL BEGIN TO LOWER THROUGH
THE DAY...WITH CEILINGS DROPPING BELOW 7000FT BETWEEN 04Z AND 08Z.
