The episode as NWS DVN wrote it up.
A potent low pressure system moved across Missouri and southern Illinois Nov. 20th and 21st, bringing the season's first snowfall to much of the area. Widespread snowfall totals of 6 to 12 inches were found across northern Iowa and the Wisconsin-Illinois border. Isolated higher amounts of 14 to 16 inches were reported. Strong northerly winds developed as the system moved off to the northeast, which created patchy blowing and drifting snow. Rain prevailed for much of the night in parts of northeast Missouri and west central Illinois limiting snowfall amounts in those areas to generally under an inch.
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 Quad Cities, IA wrote its last area forecast discussion before the first event at Nov 20, 5:23 PM CST, 37 minutes earlier.

523 PM CST FRI NOV 20 2015
.SYNOPSIS...
ISSUED AT 347 PM CST FRI NOV 20 2015
12Z UA ANALYSIS HAS THE MAIN SHORTWAVE OF THE INCOMING STORM SYSTEM
IN THE CENTRAL PLAINS. A LLJ RAN FROM TEXAS INTO THE SOUTHERN PLAINS
SUPPLYING MOISTURE FOR THE STORM SYSTEM. SATELLITE/RADAR DATA SHOW
INCREASING CLOUDS ALL DAY WITH A BAND OF PRECIPITATION FROM NORTHERN
IOWA INTO NORTHERN ILLINOIS. RADAR TRENDS THE PAST 2 HOURS SHOWS THE
ATMOSPHERE RAPIDLY SATURATING ACROSS SOUTHERN IOWA INTO WEST CENTRAL
ILLINOIS.
18Z SFC DATA HAD AN INFERRED LOW IN NORTHWEST KANSAS WITH AN
INVERTED TROF RUNNING UP INTO NEBRASKA. DEW POINTS WERE IN THE TEENS
AND 20S FROM THE WESTERN GREAT LAKES INTO THE CENTRAL PLAINS. DEW
POINTS WERE IN THE 30S AND HIGHER RAN FROM KANSAS INTO THE SOUTHERN
PLAINS.&&
.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 347 PM CST FRI NOV 20 2015
FIRST...THE START TIMES FOR ALL HEADLINES HAVE BEEN MOVED FORWARD BY
2 TO 3 HOURS. REFER TO THE RECENTLY ISSUED WSW FOR SPECIFIC TIMES.
SECOND...AMOUNTS. ALONG/NORTH OF A SIGOURNEY IOWA TO PROPHETSTOWN
ILLINOIS LINE...SNOWFALL AMOUNTS OF 8 TO 12 INCHES ARE EXPECTED. THE
HIGHEST AMOUNTS LOOK TO BE CENTERED AROUND HIGHWAY 30 ON NORTH.
SOUTH OF THIS LINE AND DOWN TO AN OTTUMWA TO JUST NORTH OF GALESBURG
LINE...6 TO 8 INCHES IS EXPECTED. SOUTH OF AN OTTUMWA TO JUST NORTH
OF GALESBURG LINE...AMOUNTS WILL TAPER DOWN FROM 5 INCHES TO AROUND
AN INCH IN THE EXTREME SOUTH.
RAP TRENDS COMBINED WITH SATELLITE/RADAR DATA INDICATE THE
ATMOSPHERE IS RAPIDLY SATURATING ACROSS THE AREA. FORCING AND
ATMOSPHERIC COOLING RESULTED IN ONLY SNOW DEVELOPING IN THE BAND OF
PRECIPITATION THAT OCCURRED ACROSS THE NORTHERN THIRD OF THE AREA
EARLIER THIS AFTERNOON.
THROUGH SUNSET...THE ATMOSPHERE WILL CONTINUE TO SATURATE WHICH WILL
ALLOW A RAPID DEVELOPMENT OF PRECIPITATION ACROSS THE AREA. THE
COMBINATION OF INCREASED FORCING AND COOLING OF THE ATMOSPHERIC
COLUMN MEANS THAT THERE SHOULD BE ONLY A BRIEF PERIOD OF A RAIN/SNOW
MIX BEFORE IT TURNS OVER TO ALL SNOW.
AFTER SUNSET...THE FORCING/MOISTURE INCREASES EVEN FURTHER WHICH
WILL ALLOW THE ATMOSPHERE TO CONTINUE COOLING. WIDESPREAD SNOW WILL
QUICKLY DEVELOP AFTER SUNSET. AS SNOW RATES INCREASE DURING THE
EVENING HOURS...THE SNOW WILL COOL DOWN ROAD TEMPERATURES AND ALLOW
ACCUMULATION TO BEGIN.
SOUTH OF I-80 A RAIN/SNOW MIX MAY HOLD ON A BIT LONGER INTO THE
EVENING BEFORE CHANGING OVER TO ALL SNOW. AGAIN...AS PRECIPITATION
RATES INCREASE DURING THE EVENING...ROAD TEMPERATURES IN THE SOUTH
THIRD WILL COOL AND ALLOW THE SNOW TO EVENTUALLY ACCUMULATE.
THE STRONGEST FORCING LOOKS TO MOVE THROUGH THE AREA BETWEEN 9 PM
AND 4 AM. THIS SHOULD BE THE TIME FRAME OF THE HIGHEST SNOWFALL
RATES AND GREATEST ACCUMULATION.
ON SATURDAY...SNOWFALL RATES WILL DECREASE AND THE SNOW WILL END
FROM WEST TO EAST DURING THE MORNING WEST OF THE MISSISSIPPI. EAST
OF THE MISSISSIPPI...THE SNOW WILL LINGER INTO MID AFTERNOON AND
THEN END.
HIGH TEMPERATURES ON SATURDAY WILL LIKELY OCCUR MID TO LATE MORNING
WITH TEMPERATURES SLOWLY FALLING DURING THE AFTERNOON.
.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 347 PM CST FRI NOV 20 2015
THE LONG TERM
WILL BEGIN BITTERLY COLD...BUT END MILDER AND WET. WITH A STRONG
POSSIBILITY OF GREATER THAN 2 INCHES OF SNOW DEPTH AS OF SUNSET
SATURDAY IN ALL BUT THE FAR SOUTH...WE SHOULD SEE A WINTER NIGHT
SATURDAY NIGHT AS HIGH PRESSURE MOVES IN OVER THE FRESH WHITE
GROUND. I HAVE GONE 1 DEGREE WARMER THAN THE COLDEST GUIDANCE...AND
THAT MIGHT NOT BE COLD ENOUGH. THIS PLACES MY LOWS IN THE ZERO TO 5
DEGREE RANGE OVER SNOW...AND IN THE UPPER SINGLE DIGITS TO LOWER
TEENS IN THE FAR SOUTH. WE OFTEN TEND OF NOT ACCOUNT FOR THE
RADIATIONAL COOLING POTENCY OF FRESH DEEP SNOW...SO I HOPE THAT
THIS AT LEAST GETS US INTO THE BALLPARK OF A TRUE WINTER NIGHT.
SUNDAY...SOUTH WINDS WILL BLOW AROUND 10 TO 15 MPH...WITH WARM
ADVECTION HELPING BOOST HIGHS INTO THE MID TO UPPER 30S OVER SNOW
FREE LOCATIONS IN THE EXTREME SOUTH...TO THE MID 20S OVER DEEP SNOW
NORTHEAST. IT WILL AGAIN BE A WINTER DAY...WITH REAL WIND CHILLS TO
THE ZERO TO -10 RANGE EARLY IN THE DAY.
SUNDAY NIGHT THROUGH TUESDAY...WE WILL MODERATE AS THE FLOW BECOME
ZONAL TO SOUTHWEST ALOFT. A DEEP TROUGH IS EXPECTED DROP INTO THE
SOUTHERN ROCKIES BY EARLY WEEK AS THIS OCCURS. OVER THE COURSE OF
SEVERAL DAYS OF SOUTHERLY FLOW ALOFT...GULF MOISTURE...WITH WELL
ABOVE NORMAL PWAT VALUES WILL AGAIN SPREAD OVER THE MIDWEST. THIS
SETS THE STAGE FOR SEVERAL DAYS OF RAIN AND THE POSSIBILITY OF
SEASONALLY HEAVY AMOUNTS. THIS BEARS WATCHING FOR A POSSIBLE
TRIBUTARY FLOOD THREAT.
