Temperatures around 20 contributed to the death of a man in his 60's.
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 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 Feb 9, 3:14 AM CST, 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 314 AM CST SAT FEB 9 2013 .DISCUSSION... 314 AM...MAIN FORECAST CONCERN/CHALLENGE THIS MORNING REMAINS THE NEXT STORM SYSTEM TO AFFECT THE AREA SUNDAY...WITH A CHANCE OF SOME LIGHT FREEZING RAIN LATE TONIGHT INTO EARLY SUNDAY MORNING... RAIN SUNDAY...AND A WINDY MONDAY. LOW CLOUDS REMAINED TRAPPED UNDER A STRONG INVERSION AS A LARGE RIDGE OF HIGH PRESSURE MOVES EAST THIS MORNING. AS WINDS TURNED MORE EASTERLY FRIDAY EVENING...CLOUDS BEGAN MOVING BACK WEST AND NOW ARE MOVING NORTH/NORTHWEST AS WINDS TURN SOUTHEAST. SOME HOLES HAVE DEVELOPED BUT CLOUDS TEND TO FILL/ADVECT BACK INTO THE HOLES. GIVEN THE STRENGTH OF THE INVERSION...COULD REMAIN MOSTLY CLOUDY FOR A GOOD PORTION OF TODAY AND HAVE TRENDED MORE PESSIMISTIC WITH SKY COVER BUT TRENDS WILL NEED TO BE MONITORED LATER THIS MORNING. UNDER CLEAR SKIES... DENSE FOG DEVELOPED FRIDAY EVENING NEAR THE WI BORDER AND FAR NORTHWEST IL. AS THE CLOUDS MOVED BACK INTO THESE AREAS...FOG LIFTED. FOG DEVELOPMENT REMAINS POSSIBLE WHERE ANY CLEARING PERSISTS PRIOR TO SUNRISE. EXTENT OF CLOUD COVER WILL IMPACT HIGH TEMPS TODAY WHICH THEN COULD IMPACT LOWS/TEMP TRENDS TONIGHT. SOUTH OF THE SNOW PACK... SOME SUN COULD EASILY PUSH TEMPS INTO THE MID/UPPER 30S AND IF THAT WERE TO HAPPEN...INCREASING HIGH/MID LEVEL CLOUDS SHOULD PUT THE BRAKES ON TEMPS DROPPING OFF LATER THIS EVENING THOUGH LOWS IN THE UPPER 20S NORTH OF I-80 STILL LOOK REASONABLE...LOWER 30S SOUTHERN CWA...THEN TEMPS SHOULD STEADY AND LIKELY BEGIN RISING A FEW DEGREES OVERNIGHT/TOWARD MORNING. TEMP TRENDS AND HOW MUCH ABOVE OR BELOW FREEZING THEY ARE WILL BE IMPORTANT FOR PRECIP TYPE...SPECIFICALLY FREEZING RAIN POTENTIAL...LATE TONIGHT/SUNDAY MORNING. LOW PRESSURE OVER COLORADO WILL MOVE NORTHEAST ACROSS THE PLAINS TONIGHT AND SUNDAY AS IT DEEPENS...THEN MOVE ACROSS THE NORTHERN LAKES REGION ON MONDAY. A FAIRLY STRONG UPPER WAVE WILL MOVE ACROSS THE AREA ON SUNDAY AND APPEARS THE BULK OF THE PRECIP WILL FALL FROM MID MORNING THROUGH MID/LATE AFTERNOON. PRECIP DURATION MIGHT ONLY BE A FEW HOURS AT ANY ONE LOCATION. THE POTENTIAL PROBLEM BECOMES ANY LIGHTER PRECIP THAT DEVELOPS AHEAD OF THIS WAVE AS STRONGER WARM AIR ADVECTION DEVELOPS DURING THE PREDAWN HOURS SUNDAY AND PERSISTS FOR A FEW HRS AFTER SUNRISE. FORECAST SOUNDINGS SHOW A LARGE WARM LAYER ALOFT. AS IT SATURATES...SOME COOLING COULD PRODUCE A FEW ICE PELLETS BUT STILL APPEARS WARM ENOUGH THAT PRECIP SHOULD BE ALL RAIN. IN ADDITION...THE LOWER LEVELS ARE RATHER DRY. SO MUCH OF THIS LIGHTER PRECIP COULD END UP BEING VIRGA AS THE THE COLUMN SATURATES. WITH THE UNKNOWN OF JUST HOW WARM SURFACE TEMPS WILL BE AROUND SUNRISE...MAINLY ACROSS THE NORTHERN HALF/THIRD OF THE CWA...AND ESPECIALLY OVER THE DEEPER SNOW PACK ACROSS THE FAR NORTHERN CWA...THINK IT IS STILL REASONABLE TO HAVE SOME MENTION OF CHANCE/SLIGHT CHANCE OF LIGHT FREEZING RAIN. DURATION OF ANY FREEZING RAIN WOULD LIKELY BE SHORT AND HAVE IT MIXED WITH RAIN IN THE GRIDS TO TRY TO CONVEY THE UNCERTAINTY WITH TEMPS. TEMPS SHOULD QUICKLY WARM ABOVE FREEZING BY MID MORNING...EVEN ACROSS THE FAR NORTH...ENDING THE THREAT OF ANY FREEZING RAIN. AS THE UPPER WAVE MOVES ACROSS THE AREA...PRECIPITABLE WATER VALUES APPROACH 1 INCH WITH SOME IMPRESSIVE OMEGA. THIS WILL LIKELY LEAD TO A FEW PERIODS OF MODERATE TO PERHAPS HEAVY RAIN... A FEW RUMBLES OF THUNDER AND RAINFALL AMOUNTS APPROACHING A HALF INCH...WITH SOME LOCALLY HIGHER AMOUNTS POSSIBLE. AS DEWPOINTS INCREASE BOTH FROM THE RAIN AND ADVECTING MOISTURE NORTH...EXPECT SOME FOG TO FORM BUT BEST CHANCE FOR ANY SIGNIFICANTLY LOWER VIS OR DENSE FOG WOULD BE OVER THE DEEPER SNOW PACK ACROSS THE FAR NORTHERN CWA. ONCE THIS WAVE SHIFTS EAST...APPEARS THE DRY SLOT WILL WRAP IN ACROSS THE AREA SUNDAY EVENING. WHILE TEMPS WILL WARM INTO THE 40S MOST AREAS BY AFTERNOON...ACTUAL DAILY HIGH TEMPS... AND STILL IN THE 40S...PERHAPS 50ISH SOUTH...MAY BE SET IN THE EARLY EVENING AHEAD OF THE COLDER AIR WHICH SPREADS ACROSS THE AREA LATE SUNDAY EVENING INTO EARLY MONDAY MORNING. NOT ALL THAT CONFIDENT HOW MUCH CLEARING THERE WILL BE...BUT ANY PRECIP AT THAT TIME WOULD ONLY BE SOME DRIZZLE WITH PERHAPS A FEW SHOWERS STILL LINGERING IN NORTHWEST INDIANA AND ALONG THE WI/IL BORDER. AS THE COLDER AIR SPREADS IN...SOME DEEPER MOISTURE WITH IT WILL LIKELY LEAD TO A FEW SNOW SHOWERS ACROSS NORTHWEST IL OVERNIGHT. THESE SNOW SHOWERS WILL PROBABLY PERSIST INTO MONDAY WITH PERHAPS A DUSTING OF SNOW POSSIBLE. THE GRADIENT WILL TIGHTEN ON SUNDAY AS THE LOW DEEPENS AND HIGH PRESSURE SLOWLY MOVES OFF THE ATLANTIC COAST. SOUTHERLY WINDS GUSTING 30 MPH TO PERHAPS 35 MPH LOOK REASONABLE FOR SUNDAY. SPEEDS WILL LIKELY DIMINISH SUNDAY EVENING AND SHIFT SOUTHWESTERLY BUT AS THE COLDER AIR SPREADS OVERNIGHT BUT ESPECIALLY ON MONDAY...STILL LOOKS QUITE WINDY WITH WESTERLY WINDS GUSTING PERHAPS AS HIGH AS 40 MPH. WEAK HIGH PRESSURE/RIDGING IS EXPECTED ACROSS THE SOUTHERN LAKES TUESDAY/WEDNESDAY WHICH WILL ALLOW FOR DRY CONDITIONS. IF SUNSHINE MATERIALIZES DURING THIS PERIOD...HIGHS LIKELY TO BE ABOVE NORMAL WITH LOWER 40S POSSIBLE WEDNESDAY ACROSS PARTS OF THE AREA AND PERHAPS ACROSS THE ENTIRE AREA BY THURSDAY. BUT BY THIS TIME PERIOD...CONFIDENCE IS FAIRLY LOW. ECMWF HAS BEEN SOMEWHAT CONSISTENT WITH A CLIPPER LIKE LOW MOVING ACROSS THE LAKES AND NOW SLOWS AND DEEPENS THIS LOW OVER THE EASTERN LAKES INTO EARLY NEXT WEEKEND. DOES SEEM TO BE SOME CONTINUITY ON A COLDER PATTERN INTO NEXT WEEKEND. CMS && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 09Z... * MVFR CIGS CONTINUING THROUGH MID/LATE MORNING. MDB //DISCUSSION...UPDATED 09Z... MVFR STRATUS CONTINUES ACROSS THE TERMINALS WITH PERIODIC BREAKS DEVELOPING THEN QUICKLY FILLING IN. BASED ON THE EXPANSE WILL EXTEND THE PERIOD OF BKN/OVC MVFR CIGS THROUGH THE MORNING BY SEVERAL HOURS BUT CONFIDENCE IN WHEN EXACTLY SCATTERING WILL OCCUR IS STILL LIMITED. MDB FROM 06Z... HIGH PRESSURE IS PRETTY MUCH RIGHT OVER THE TERMINALS LATE THIS EVENING RESULTING IN CALM TO LIGHT AND VARIABLE WINDS...WITH A TENDENCY TO SHIFT TO LIGHT SOUTHEAST WINDS THROUGH THE OVERNIGHT. CIGS REMAIN THE BIGGEST CHALLENGE WITH AN EXPANSIVE AREA OF MAINLY MVFR STRATUS ACROSS THE AREA WHICH HAS BEEN REINFORCED BY LIGHT EAST TO SOUTHEAST LOW LEVEL FLOW. SOME IFR IS ALSO OCCURRING ON THE EDGES OF A BREAK IN THE CLOUDS OUT TOWARDS RFD. THIS BREAK IS STEADILY FILLING IN HOWEVER. THE MAIN CHALLENGE WILL BE TIMING IMPROVEMENT. SATELLITE TRENDS SHOW A SLIGHT DECREASE IN CLOUD COVER OVER SOUTHERN LAKE MICHIGAN WORKING WESTWARD AND IT IS POSSIBLE THAT THE CHICAGO AND NW INDIANA TERMINALS SCATTER OR AT LEAST SEE BREAKS EARLIER THAN WHAT IS CURRENTLY EXPECTED. TO THE WEST TOWARDS RFD...CLOUDS LOOK TO HANG ON LONGER DURING THE MORNING GIVEN THE INVERSION THAT HAS SET UP AND ANY MEANINGFUL BREAKS IN THE CLOUDS CURRENTLY FILLING IN. BASED ON RECENT OBSERVED TRENDS AT UPSTREAM SITES...IFR AREAS NEAR RFD MAY IMPROVE TO MVFR IN THE NEXT FEW HOURS. SHOULD NEW BREAKS DEVELOP OUT NEAR THE RFD AREA...THEN FOG MAY QUICKLY DEVELOP BUT THIS WINDOW OF OPPORTUNITY MAY CLOSE A FEW HOURS FROM NOW AS CIRRUS STREAMS INTO THE AREA. PROVIDED THAT SCATTERING/CLEARING DOES OCCUR LATER TODAY...THEN QUIET WEATHER WILL PREVAIL WITH SOUTHEAST WINDS IN THE 10-12 KT RANGE...WITH SOME SLACKENING OF SPEEDS DURING THE EVENING. RAIN AND CIG/VSBY RESTRICTIONS BECOME MORE LIKELY SUNDAY MORNING AS STRONG LOW PRESSURE PASSES TO THE NORTHWEST OF THE REGION. MDB //ORD AND MDW CONFIDENCE...UPDATED 09Z... * HIGH CONFIDENCE IN MVFR CIGS BUT LOW CONFIDENCE IN TIMING OF SCATTERING/CLEARING LATE MORNING/EARLY AFTERNOON. MDB //OUTLOOK FOR ORD/MDW FOR 12Z SUNDAY-12Z FRIDAY...UPDATED 00Z... SUNDAY...RAIN/IFR LIKELY. MONDAY...MVFR. TUESDAY...VFR. WEDNESDAY...VFR. THURSDAY...VFR. BMD && .MARINE... 242 AM CST THE BIG EAST COAST LOW OFFSHORE OF CAPE COD WILL CONTINUE TO MOVE NORTHEASTWARD WHILE AN EXPANSIVE AREA OF HIGH PRESSURE MOVES FROM LAKE MICHIGAN EASTWARD. THIS WILL KEEP LIGHT WINDS ACROSS THE LAKE THIS MORNING BEFORE THEY INTENSIFY FROM THE SOUTH LATER TODAY. LOW PRESSURE WILL DEVELOP OVER EASTERN COLORADO AND MOVE NORTHEASTWARD INTO THE UPPER MISSISSIPPI RIVER VALLEY SUNDAY AND THEN ACROSS NORTHERN LAKE MICHIGAN MONDAY. WARMER AIR WILL SURGE NORTHWARD ACROSS MUCH OF THE AREA SUNDAY AHEAD OF THE LOW WHICH WILL SET UP AN INVERSION OVER THE COLD LAKE WATERS. THIS WILL KEEP MAXIMUM GUST POTENTIAL LIMITED AS LOW LEVEL WINDS RAMP UP BUT IT STILL APPEARS THAT WINDS OF 30 KT WILL BE PRESENT JUST BELOW THE INVERSION BUT 35 KT GALES ARE STILL A POSSIBILITY BUT CONFIDENCE IS LIMITED IN HOW FREQUENT GALES MIGHT BE. COLDER AIR WILL WRAP IN BEHIND THE LOW FROM THE SOUTHWEST ON MONDAY AS LOW LEVEL WINDS INCREASE FURTHER. THE STRONGEST WINDS ARE EXPECTED AFTER THE COLD AIR ARRIVES MONDAY WHILE THE LOW IS CROSSING NORTHERN LAKE HURON. THIS WILL SUPPORT 40-45 KT GALES ACROSS CENTRAL AND SOUTHERN PARTS OF THE LAKE ON MONDAY AND MONDAY EVENING. WILL HOLD OFF ON A GALE WATCH FOR NOW GIVEN THE UNCERTAINTY FOR SUNDAY BUT HAVE HIGH CONFIDENCE IN GALES MONDAY/MONDAY EVENING. IT DOES APPEAR THAT THERE WOULD BE A BREAK BETWEEN ANY GALES SUNDAY AND THOSE EXPECTED MONDAY SO TWO SEPARATE HEADLINES MAY BE NEEDED. WINDS WILL THEN GRADUALLY DIMINISH AS THE SYSTEM EXITS LATER TUESDAY WITH QUIETER WEATHER EXPECTED THROUGH MID WEEK. BEYOND THAT...A SERIES OF LOWS MAY CROSS THE GREAT LAKES LATE NEXT WEEK BRINGING MODEST PERIODS OF INCREASED WIND SPEEDS AND MORE PERSISTENT PERIODS OF NORTH TO NORTHWEST WINDS FOLLOWING THE PASSAGE OF THESE LOWS.
