The episode as NWS LOT wrote it up.
A major tornado outbreak impacted the Midwest and Ohio Valley on November 17th. A powerful low pressure system across the plains states steered warmth and moisture northward for nearly two days, with dew points rising into the mid 60s. This coupled with temperatures around 70 resulted in unseasonably strong instability for thunderstorms to develop. High wind shear and a cold front sweeping eastward made up the remaining ingredients of an environment favorable for supercells capable of long-lived significant tornadoes. Within the WFO LOT county warning area, ten tornadoes were confirmed, including three EF-2 tornadoes. As the event evolved, the system became linear with numerous reports of straight line wind damage. Behind the thunderstorms, a wake low developed with wind gusts to around 60 mph.
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 Chicago, IL wrote its last area forecast discussion before the first event at Nov 17, 12:40 PM CST, 33 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1240 PM CST SUN NOV 17 2013
.RADAR UPDATE...
1240 PM CDT
HAVE SEEN A DEBRIS BALL SIGNATURE ON REFLECTIVITY AND CORRELATION
COEFFICIENT WITH THE SUPERCELL IN WILL COUNTY. THE NEXT
SCAN...WHICH IS THE MOST RECENT AT 1836Z...HAS APPEARED TO HAVE A
SURGE ONCE AGAIN IN THE OUTFLOW WRAPPING AROUND THIS. VERY HIGH
VELOCITIES ARE SEEN WITH THIS AREA DESPITE AT A PRETTY POOR RADAR
ANGLE.
RADAR SIGNATURES FOR THE STORMS MOVING EASTWARD ACROSS NORTH
CENTRAL IL ARE SHOWING VELOCITY FINGERS AND BACKSIDE REFLECTIVITY
DRYING VERY EVIDENT OF STRONG WINDS. ESTIMATES OF 70 MPH WINDS
HAVE COME IN FROM THE AMBOY AREA WITH THESE STORMS.
.MESOSCALE DISCUSSION...
1220 PM CDT
STORM ENTERING WILL COUNTY HAS SHOWN SOME SIGNS OF BEING MORE
REAR-FLANK DOWNDRAFT DOMINANT...HOWEVER IT CONTINUES TO SHOW SIGNS
OF TRYING TO DEVELOP PERSISTENT INFLOW AND A ROTATION ON ITS
LEADING EDGE. GIVEN THE ENVIRONMENT AND HISTORY WITH THIS
STORM...HAVE FELT IT PRUDENT TO ISSUE A TORNADO WARNING INTO WILL
COUNTY. THERE HAS EVEN BEEN A REPORT FROM GRUNDY COUNTY OF DEBRIS
FALLING FROM THE AIR WITH VERY LOW VISIBILITY...SO A TORNADO COULD
BE ONGOING.
FURTHER TO THE WEST...THE SYNOPTIC COLD FRONT IS ENTERING THE
WESTERN FORECAST AREA WITH A 69 KT GUST AT STERLING. THE LOW-LEVEL
LAPSE RATES STEEPEN IMMEDIATELY WITH THIS FRONT AND GIVEN THE LINE
OF SHOWERS/STORMS ALONG IT...HE VERY HIGH WINDS JUST OFF THE
SURFACE APPEAR TO BE TAPPED. THIS SHOULD PROGRESS A WAYS EAST
INTO THE FORECAST AREA PACKING A SIMILAR WIND PUNCH...BUT AT LEAST
PRODUCE WINDS OF 45 MPH PLUS THE ENTIRE WAY.

&&
.DISCUSSION...
304 AM CST
HIGH SEVERE WEATHER POTENTIAL ACROSS MUCH OF THE AREA TODAY WITH
TORNADOES AND DAMAGING STRAIGHT LINE WINDS A SIGNIFICANT THREAT.
SYNOPSIS...NEAR TERM FOCUS CONTINUES TO BE SEVERE WEATHER THREAT AS
A MAJOR FALL STORM SYSTEM TAKES SHAPE AND MOVES ACROSS THE REGION.
WATER VAPOR IMAGERY SHOWS A BROAD UPPER TROUGH PIVOTING ACROSS THE
MID SECTION OF THE COUNTRY WITH EVENING UPPER AIR ANALYSIS SHOWING A
150 KT UPPER JET DIGGING DOWN ITS WESTERN FLANK. AT THE SAME TIME A
SUB TROPICAL JET OF AROUND 120 KT IS STRETCHED FROM OKLAHOMA UP THE
OHIO VALLEY. SEVERAL SHORTWAVES ARE EMBEDDED IN THE SOUTHWESTERLY
FLOW AHEAD OF THE TROUGH WI ONE WAVE CROSSING NORTHWEST ILLINOIS
EARLY THIS MORNING AND A HINT OF ANOTHER ACROSS EASTERN KANSAS. AT
THE SURFACE...ONE AREA OF LOW PRESSURE IS STRETCHED FROM NORTHERN
MINNESOTA ACROSS LAKE SUPERIOR WITH ANOTHER LOW MOVING NORTHEAST
FROM CENTRAL KANSAS. SYNOPTICALLY...THE UPPER TROUGH WILL AMPLIFY AS
THE UPPER JET ROUNDS THE BASE WITH IT TAKING ON A NEGATIVE TILT AS
IT PIVOTS ACROSS THE LOCAL AREA THROUGH THE AFTERNOON. THIS WILL
CAUSE THE SURFACE LOW OVER KANSAS TO CONTINUE NORTHEAST REACHING
SOUTHERN WISCONSIN BY EARLY AFTERNOON. THE LOW WILL THEN DEEPEN AS
THE UPPER TROUGH AMPLIFIES AND CATCHES UP WITH IT ACROSS NORTHERN
LAKE MICHIGAN LATE THIS AFTERNOON. A COLD FRONTAL BOUNDARY WILL
CROSS THE AREA DURING THE AFTERNOON.
DETAILS FOR TODAY...CONVECTION CONTINUES TO WORK NORTHWARD ACROSS
THE NORTHWEST HALF OR SO OF THE AREA EARLY THIS MORNING IN
CONJUNCTION WITH THE AFOREMENTIONED SHORTWAVE. THIS WAVE IS
COINCIDENT WITH A TIGHTENING LOW/MID LEVEL BAROCLINIC ZONE/WARM
FRONT THAT IS LIFTING NORTHWARD. STEADY ASCENT WILL CONTINUE OVER
THIS BOUNDARY WHICH WILL PROGRESS NORTHWARD THROUGH DAYBREAK KEEPING
AT LEAST SCATTERED CONVECTIVE DEVELOPMENT POSSIBLE ACROSS THE
NORTHERN CWA BEFORE LIFTING NORTH. HAVE NOT SEEN MUCH IN THE WAY OF
WIND GUSTS WITH THE PRECIP THUS FAR WITH INTENSITY HAVING WANED INTO
THE OVERNIGHT HOURS...BUT SOME PULSEY CORES ARE POSSIBLE WITH SOME
SMALL HAIL. SATELLITE IMAGERY SHOWS A FAIR AMOUNT OF SCT-BKN SKIES
UPSTREAM OF THE AREA WITH A MORE WIDESPREAD AREA OF CLOUDS WORKING
NORTHWARD TO THE WEST OF THE CWA. SUSPECT THAT THERE WILL BE BREAKS
IN THE CLOUDS ACROSS PORTIONS OF THE CWA THIS MORNING.
ATTENTION TURNS TO SEVERE POTENTIAL THROUGH THE REST OF THE DAY AS
THE ABOVE SYNOPTIC EVOLUTION COMMENCES. BOTH DYNAMIC AND
THERMODYNAMIC ASPECTS OF THE SYSTEM ARE IMPRESSIVE AND WILL COME
TOGETHER TO PRODUCE AN OUTBREAK OF SEVERE WEATHER ACROSS THE REGION.
THE MAIN QUESTION FOR THE LOCAL AREA WILL BE THE AMOUNT OF COVERAGE
AS THE SYSTEM WORKS THROUGH INTO THE LATE AFTERNOON. THE WESTERN
UPPER JET WILL ROUND THE BASE OF THE TROUGH AND NOSE INTO THE AREA
FROM THE SOUTHWEST DURING THE LATE MORNING AND EARLY AFTERNOON. THIS
JET WILL ALSO COUPLE WITH THE SUB-TROPICAL JET ALREADY IN PLACE
ACROSS THE OHIO VALLEY. IN ADDITION...A 85-90 KT MID LEVEL SPEED MAX
WILL NOSE IN UNDERNEATH THE UPPER JET DURING THIS TIME AS WELL. THE
COMBINATION OF THESE FEATURES AND THE DEEPENING SURFACE TROUGH WILL
PROVIDE DEEP LAYER SHEAR VALUES OF 55-60 KT ACROSS MUCH OF THE AREA
BY MIDDAY...WITH AN INCREASE TO NEAR 70 KT ACROSS THE SOUTHEASTERN
CWA THIS AFTERNOON...WITH 0-1KM SHEAR VALUES OF AROUND 40 KT.
UNSEASONABLY STRONG INSTABILITY WILL DEVELOP AS DEW POINTS RISE INTO
THE LOWER 60S WITH CAPE VALUES OF AROUND 1000 J/KG. FORECAST
SOUNDINGS SHOW HIGH VALUES OF LOW LEVEL CAPE WITH 150 TO EVEN 200
J/KG IN THE LOWEST 3 KM. ALL OF THIS RESULTS IN IMPRESSIVE VALUES
FOR VARIOUS SEVERE WEATHER PARAMETERS. BASED ON ALL OF THIS EXPECT
THAT STORMS WILL INITIATE BY LATE MORNING OVER OR JUST SOUTHWEST/WEST OF
THE SOUTHWEST CWA AS THE ABOVE SYNOPTIC FEATURES ADVANCE NORTHEAST.
COVERAGE OF STORMS LOOKS TO TAKE OFF EARLY THIS AFTERNOON AS THE
COUPLING OF THE MID/UPPER JETS MAXIMIZES AND CONTINUES THROUGH THE
AFTERNOON. THE SEVERE THREAT WILL MARKEDLY INCREASE AS THIS OCCURS
AS WELL. THE RATE AT WHICH COVERAGE INCREASES IS STILL SOMEWHAT
UNCERTAIN...AT LEAST THROUGH MIDDAY...WITH IT POSSIBLE THAT A FEW
STORMS DEVELOP INITIALLY WITH A MORE RAPID INCREASE HOLDING OFF
UNTIL EARLY AFTERNOON WITH THE ARRIVAL OF BETTER FORCING. THE MYRIAD
OF AVAILABLE CONVECTIVE ALLOWING GUIDANCE RUNS THE GAMUT OF COVERAGE
SCENARIOS. THE LATEST SPC DAY 1 OUTLOOK LINES UP WELL WITH LOCAL
THINKING PLACING THE HIGHEST RISK FROM BASICALLY CHICAGO SOUTH TO
FORD COUNTY AND POINTS EAST. THIS AREA WILL LINE UP WELL WITH THE
BEST FORCING PARAMETERS AND TIMING OF INCREASING COVERAGE THIS
AFTERNOON. THE REMAINDER OF THE CWA TO THE WEST INCLUDING THE
ROCKFORD AREA IS IN A MODERATE RISK AND MAY BE MORE IN LINE WITH THE
INITIAL DEVELOPMENT. AS FAR AS THREATS...THE STRONG SHEAR AND
INSTABILITY WILL POINT TO DISCRETE SUPERCELL DEVELOPMENT WITH AN
EVENTUAL EVOLUTION INTO A SQUALL LINE LATER TODAY. IT IS POSSIBLE
THAT MUCH OF THE ACTIVITY REMAINS FAIRLY DISCRETE ACROSS THE CWA
WITH EVOLUTION INTO A PREDOMINATELY LINEAR STRUCTURE TAKING PLACE
OVER OR JUST EAST OF THE EASTERN CWA. GIVEN THE STRONG LOW LEVEL
SHEAR AND INSTABILITY...TORNADOES ARE A DEFINITE THREAT ALONG WITH
DAMAGING WINDS FOLLOWED BY LARGE HAIL. THE STRONG SHEAR AND
POTENTIAL FOR MAINTENANCE OF DISCRETE CELLS SUGGEST THE POTENTIAL
FOR STRONGER AND LONGER TRACKED TORNADOES SHOULD THEY OCCUR.
THE OTHER HIGHLIGHT IS THE SYNOPTIC NON-THUNDERSTORM WINDS.
SOUTHERLY SPEEDS WILL INCREASE THROUGH THE MORNING...ESPECIALLY IF
ANY MEANINGFUL CLEARING CAN OCCUR AS PRESSURE FALLS INCREASE AHEAD
OF THE LOW. THE BIGGEST CONCERN HOWEVER IS WINDS BEHIND THE COLD
FRONT WHICH WILL CROSS THE AREA LATER THIS AFTERNOON. THE STRONG
GRADIENT AND ASSOCIATED PRESSURE RISES ARE EXPECTED TO ALLOW FOR
STRONG MIXING AND GENERATION OF WIND GUSTS THAT COULD TOP 50 KT
ACROSS MUCH OF THE CWA...ESPECIALLY FROM THE NORTHERN CHICAGO
SUBURBS BACK TOWARDS THE MENDOTA AREA AND POINTS SOUTH. HAVE
UPGRADED THIS PORTION OF THE WIND ADVISORY TO A HIGH WIND WARNING
THIS AFTERNOON STARTING TOWARD MIDDAY...WITH THE HIGHEST
WINDS...OUTSIDE OF STORMS...THIS AFTERNOON.
MDB
TONIGHT THROUGH SATURDAY...
LOW PRESSURE WILL QUICKLY BE LIFTING ACROSS THE NORTHERN LAKES
THIS EVENING AND INTO WESTERN QUEBEC MONDAY MORNING...WHILE STILL
DEEPENING WHILE HIGH PRESSURE STRENGTHENS ACROSS THE PLAINS
TONIGHT AND CONTINUES TO STRENGTHEN AS IT MOVES ACROSS THE OHIO
VALLEY AND SOUTHERN LAKES REGION MONDAY NIGHT. THE STRONGEST
WINDS/GUSTS SHOULD DIMINISH QUICKLY EARLY THIS EVENING BUT IT WILL
REMAIN WINDY THROUGH THE EARLY MORNING HOURS...GRADUALLY
DIMINISHING OVERNIGHT. WRAP AROUND SHOWERS WILL BE POSSIBLE FOR A
FEW HOURS THIS EVENING...MAINLY ACROSS FAR NORTHERN IL...THEN
SHOULD SEE CLEARING SKIES. MUCH COLDER AIR WILL SPREAD ACROSS THE
REGION WITH LOWS IN THE MID/UPPER 30S BUT COMBINED WITH THE GUSTY
WESTERLY WINDS...WIND CHILLS WILL RANGE FROM THE MID 20S TO AROUND
30 RANGE BY MORNING.
MONDAY WILL REMAIN BREEZY WITH HIGHS IN THE LOWER/MID 40S WITH
MAINLY SUNNY SKIES. WINDS SHOULD STEADILY DIMINISH FROM MID
AFTERNOON THROUGH SUNSET AS THE HIGH CONTINUES TO BUILD EAST.
LIGHT WINDS AND GENERALLY CLEAR SKIES SHOULD ALLOW FOR A FAST TEMP
DROP MONDAY EVENING WITH THE USUAL COLD SPOTS PERHAPS AS LOW AS
THE LOWER 20S...BUT WITH WEAK WARM AIR ADVECTION OVERNIGHT...TEMPS
MAY LEVEL OFF AT SOME POINT. SOUTHERLY FLOW RETURNS TUESDAY AND
WITH MOSTLY SUNNY SKIES EXPECTED...HIGHS INTO THE UPPER 40S LOOK
REASONABLE WITH GUIDANCE SUGGESTING LOWER 50S COULD BE REACHED
THUS TEMPS COULD BE SLIGHTLY WARMER.
RETURN MOISTURE COMBINED WITH WEAK WAVES LIFTING ACROSS THE AREA
NOW APPEAR SUFFICIENT TO PRODUCE SOME SHOWERS WEDNESDAY INTO
WEDNESDAY NIGHT. THE MODELS ARE IN MUCH BETTER AGREEMENT WITH
THIS SOLUTION BUT STILL SOME TIMING DIFFERENCES AS THE ECMWF HOLDS
OFF PRECIP UNTIL WEDNESDAY NIGHT FOR MUCH OF THE AREA AND A SLOWER
TIMING COULD MEAN WARMER TEMPS ON WEDNESDAY. A COLD FRONT THEN
SAGS SOUTH INTO THE AREA THURSDAY AHEAD OF ANOTHER VERY STRONG
HIGH BUILDING SOUTH INTO THE NORTHERN PLAINS. AS THE UPPER TROUGH
DIGS ACROSS THE LAKES REGION...ANOTHER WAVE MOVES EAST/NORTHEAST
ACROSS THE SOUTHERN LAKES AND OHIO VALLEY. TIMING OF COLDER AIR
ALONG WITH END TIME OF PRECIP ALL REMAIN UNCERTAIN FROM THIS
DISTANCE. CURRENT TRENDS WOULD SUGGEST A COLD RAIN WITH A BRIEF
MIX BEFORE ENDING. HOWEVER...GIVEN THE DIFFERENCES...ITS DIFFICULT
TO LOWER OR RAISE POPS FOR VARIOUS TIME PERIODS. THUS HAVE CHANCE
POPS FOR THE ENTIRE WEDNESDAY NIGHT THROUGH FRIDAY NIGHT TIME
PERIOD AND THERE WILL LIKELY BE PERIODS OF NO PRECIP DURING THIS
TIME. CMS

POWERHOUSE STORM WILL INTENSIFY RAPIDLY THIS AFTERNOON AND
TONIGHT AS IT MOVES FROM NORTHERN ILLINOIS TO SOUTHERN ONTARIO.
THERE WILL BE A BIT OF A LULL IN THE WINDS THIS MORNING...AND
WINDS WILL BE JUST BELOW GALE FORCE FOR A BIT BUT WILL MAINTAIN
THE GALE THROUGH MID AFTERNOON. AS THE LOW PRESSURE MOVES ACROSS
THE NORTH END OF THE LAKE THIS AFTERNOON A STRONG COLD FRONT WILL
SWEEP RAPIDLY ACROSS THE LAKE. A LARGE PRESSURE FALL/RISE COUPLET
WILL MOVE ACROSS NORTHERN IL THIS AFTERNOON AND OVER CENTRAL AND
SOUTHERN LAKE MICHIGAN THIS EVENING. EXPECT WINDS TO INTENSIFY
LATE AFTERNOON AND EVENING WITH GUSTS OF 50 TO 60 KTS. NORTH PART
OF THE LAKE MAY SEE SOME NEAR STORM FORCE GUSTS LATE EVENING
THROUGH THE OVERNIGHT HOURS...BUT NOT AS STRONG AS THE SOUTH AND
CENTRAL. SO HAVE MAINTAINED THE GALE FOR THE NORTH. GALES WILL
THEN CONTINUE OVER THE ENTIRE LAKE THROUGH MONDAY AFTERNOON.
FOR THE NEARSHORE...WINDS WILL RAMP UP TO STORM FORCE GUSTS BY
LATE AFTERNOON BUT DROP BACK TO GALES THIS EVENING...SO A SHORTER
PERIOD OF POTENTIAL STORM FORCE WINDS NEARSHORE.

On the east side of Valparaiso, numerous power poles were snapped and trees were blown down. County Road 600N was closed between 300E and 400E due to several high tension poles and power lines down across the road.
The tornado touched down in Goodland causing several large grain bins to cave in on themselves with some of the surrounding scaffolding collapsing.

This is a continuation of a tornado that touched down in Newton County at 1:27 PM CST. The tornado mainly passed over open fields; however, near the end of the path an outbuilding was destroyed and small farm equipment moved, including one piece that was rolled into a grain storage bin. Debris was noted as far as a mile downstream. The highest winds were estimated to around 100 mph.
