The episode as NWS IND wrote it up.
A strong low pressure system moved just north of central Indiana, producing widespread rainfall followed by very strong winds. Non-thunderstorm winds gusted over 55 mph at times. The rain eventually changed to snow. Minor snow accumulations were observed. However, a truck driver was killed in a crash on Interstate 65 in Jackson County after loosing control while crossing an icy bridge.
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 Indianapolis, IN wrote its last area forecast discussion before the first event at Dec 20, 2:42 PM EST, 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 242 PM EST THU DEC 20 2012 .UPDATE... THE SYNOPSIS...NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW. && .SYNOPSIS... ISSUED AT 240 PM EST THU DEC 20 2012 A VERY POTENT LOW PRESSURE SYSTEM OVER CENTRAL ILLINOIS THIS AFTERNOON WILL MOVE RAPIDLY THROUGH THE GREAT LAKES OVER THE NEXT 24 HOURS...BRINGING RAINFALL...EMBEDDED THUNDERSTORMS...VERY STRONG WINDS...AND FINALLY SNOW AND COLD CONDITIONS TO CENTRAL INDIANA THIS EVENING AND TONIGHT. QUIET WEATHER WILL RETURN FOR THE WEEKEND...FOLLOWED BY ONE OR MORE ADDITIONAL STORM SYSTEMS IN THE EARLY TO MIDDLE PORTION OF THE COMING HOLIDAY WEEK...WHICH MAY BRING RAIN AND PERHAPS ADDITIONAL SNOW BACK TO THE AREA. && .NEAR TERM /REST OF THIS AFTERNOON THROUGH FRIDAY/... ISSUED AT 240 PM EST THU DEC 20 2012 FORECAST THIS PERIOD IS EXTREMELY TRICKY. WHILE WE HAVE A GOOD HANDLE ON WHAT WEATHER CONDITIONS WILL OCCUR...HOW BEST TO CONVEY THIS VIA THE HEADLINES/ADVISORIES/WARNINGS IS THE ULTIMATE QUESTION. AS THE LOW PRESSURE SYSTEM CURRENTLY CENTERED OVER ILLINOIS RAPIDLY INTENSIFIES AND MOVES TOWARD THE GREAT LAKES REGION...THE PRESSURE GRADIENT WILL TIGHTEN SIGNIFICANTLY AS A COLD FRONT IS DRAGGED ACROSS CENTRAL INDIANA LATE THIS AFTERNOON AND INTO THE EVENING. TEMPERATURE WILL BEGIN TO DROP AND PRECIPITATION SHOULD CHANGE TO LIGHT SNOW BY THIS EVENING. PROBLEM IS...WINDS WILL BE HOWLING FROM THE WEST SUSTAINED AROUND 30 TO 40 MPH WITH GUSTS IN EXCESS OF 55 MPH FOR PERIODS. BECAUSE OF THESE STRONGER WINDS A HIGH WIND WARNING WAS HOISTED FOR THE ENTIRE CWA. SNOW AMOUNTS LOOK LESS IMPRESSIVE THEN PREVIOUS MODEL RUNS...BUT DID NOT FEEL CONFIDENT ENOUGH TO LOWER AMOUNTS SIGNIFICANTLY. WILL STICK TO AN AVERAGE OF 1 TO 3 FOR THE WINTER WEATHER ADVISORY AREA...AND HALF AN INCH TO ONE INCH FOR THE SOUTHERN HALF OF THE AREA. (WITH I-70 ROUGHLY THE DIVIDING LINE.) VISIBILITIES UPSTREAM ACROSS PORTIONS OF ILLINOIS AND MISSOURI INDICATE VERY LOW VISIBILITIES OF LESS THAN A MILE...1/4 TO 1/2SM IN SOME LOCATION DUE TO THE VERY STRONG WINDS AND MODERATE SNOW THAT IS OCCURRING. WITH NOT AS MUCH SNOW EXPECTED IN THIS AREA IT/S HARD TO SAY HOW MUCH OF AN IMPACT LIGHT SNOW MIXED WITH THESE VERY STRONG WINDS WILL HAVE ON LOCAL VISIBILITIES. AM CONCERN ABOUT BRIEF "BLIZZARD-LIKE" CONDITIONS AT TIMES TONIGHT FOR THE CWA. A BLIZZARD WARNING CERTAINLY IS NOT WARRANTED AND WILL TRY TO HIT HARD IN THE WORDING THAT THESE STRONG WINDS COMBINED WITH LIGHT SNOW CAN MAKE FOR DANGEROUS VISIBILITY RESTRICTIONS...BOTH IN THE TEXT OF THE WARNING AND ADVISORY...AS WELL AS THE HWO. MODELS HAVE SLOWED DOWN THE COMPLETE DEPARTURE OF THE SYSTEM JUST A BIT...AND THUS WILL HOLD ONTO SLIGHT CHANCE TO MIDDLING CHANCE POPS OVER THE NORTHEASTERN HALF OF THE FORECAST AREA FRIDAY MORNING...AND SLIGHT CHANCE TO LOW CHANCE POPS FAR NORTHEASTERN CORNER FRIDAY AFTERNOON...AS DEEPER MOISTURE WILL BE ON THE WAY OUT...A FEW LAKE ENHANCED SNOW SHOWERS MAY LINGER OVER THIS AREA. FINALLY...ON TEMPS...HAVE RELIED HEAVILY ON RAW MODEL CONSENSUS AND LATEST TEMP TRENDS AS A STARTING POINT...WITH MOS AT A GREAT DISADVANTAGE IN EXTREMELY RAPIDLY CHANGING CONDITIONS AND WITH NON DIURNAL PROGRESSION. BULK OF MAX TEMPERATURES WERE MET EARLIER THIS AFTERNOON AND WILL CONTINUE TO FALL FOR THE REST OF TODAY AND OF COURSE INTO TONIGHT. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... ISSUED AT 240 PM EST THU DEC 20 2012 FORECAST FOCUS IS ON TEMPERATURES AND SINCE GUIDANCE IS SIMILAR A A BLEND SUFFICIENT. HIGH PRESSURE BUILDS IN FRIDAY NIGHT INTO THE WEEKEND AND A DRY...MUCH MORE QUIET FORECAST PERIOD RESULTS. ON TEMPS...UNDERCUT GUIDANCE...ESPECIALLY DURING THE OVERNIGHTS...WITH *POSSIBLE* FRESH SNOWFALL ON THE GROUND. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... ISSUED AT 344 AM EST THU DEC 20 2012 ACTIVE AND COMPLEX WEATHER PATTERN RETURNS FOR MUCH OF THE EXTENDED WITH TWO SYSTEMS POTENTIALLY SET TO IMPACT THE REGION AS A WARM FRONT BECOMES ALIGNED NEAR THE OHIO RIVER. HIGH PRESSURE WITH A PREDOMINANT NORTHWEST FLOW ALOFT WILL BE PRESENT ACROSS THE OHIO VALLEY FOR SUNDAY...WITH COOL DRY CONDITIONS ANTICIPATED WITH A STEADY INCREASE IN CLOUDS BY SUNDAY NIGHT AS LOW LEVEL MOISTURE LIFTS NORTH INTO THE REGION. EXTENDED MODEL GUIDANCE IN GENERAL AGREEMENT THIS MORNING IN A WARM FRONT SETTING UP NEAR THE OHIO RIVER ON MONDAY WITH A WEAK SURFACE WAVE MOVING ALONG THE BOUNDARY THROUGH EARLY TUESDAY. AT THIS POINT...STILL PREFER TO TREND THE FORECAST TOWARDS THE FLATTER AND MORE PROGRESSIVE UPPER LEVEL PATTERN WITH RESPECT TO THE FIRST WAVE. THE POLAR VORTEX PRESENT OVER THE CANADIAN MARITIMES SHOULD SERVE AS A BLOCK AND LIMIT AMPLIFICATION OF THE UPPER LEVEL WAVE ACCOMPANYING THE INITIAL SURFACE LOW MONDAY INTO EARLY TUESDAY. WITH THE FRONT AND DEEPER FORCING REMAINING JUST SOUTH OF THE REGION...WILL MAINTAIN LOW CHANCE POPS FOR MONDAY AND TUESDAY AND KEEP A RAIN/SNOW MIX OR JUST SNOW WITH A PREDOMINANT NORTHERLY COMPONENT TO THE LOW LEVEL FLOW. GREATER INTEREST CONTINUES TO FOCUS ON THE SECOND SURFACE WAVE SET TO IMPACT MUCH OF THE EASTERN U S FOR MIDWEEK. STRONG UPPER LEVEL LOW WILL MOVE INTO THE PACIFIC NORTHWEST ON MONDAY...THEN AMPLIFY SIGNIFICANTLY TUESDAY ACROSS THE ROCKIES. THE INTENSIFYING UPPER LOW WILL PROMOTE SURFACE CYCLOGENESIS OVER THE LOWER MISSISSIPPI VALLEY TUESDAY NIGHT INTO WEDNESDAY WITH THE STORM DEEPENING AS IT MOVES NORTHEAST AND EVENTUALLY TRANSFERS ITS ENERGY TO A LOW OFF THE MID ATLANTIC COAST BY THURSDAY. WHILE THE EXTENDED MODELS DIFFER IN THE DETAILS WITH REGARDS TO TIMING OF IMPACTS AND SPECIFIC TRACK OF THE SYSTEM...CONFIDENCE CONTINUES TO INCREASE IN A LARGE AND POTENTIALLY SIGNIFICANT WINTER STORM IMPACTING THE OHIO VALLEY AND GREAT LAKES TUESDAY NIGHT THROUGH THURSDAY. WITH ALL AVAILABLE MODEL GUIDANCE SUGGESTIVE OF A SYSTEM TRACK ANYWHERE FROM THE OHIO VALLEY INTO THE SOUTHEAST...WILL FOCUS PRECIP AS EITHER A RAIN/ SNOW MIX OR ALL SNOW AT THIS TIME. && .AVIATION /DISCUSSION FOR 201800Z TAF ISSUANCE/... ISSUED AT 1219 PM EST THU DEC 20 2012 POOR FLYING CONDITIONS EXPECTED THROUGH THE PERIOD. CEILINGS STARTING OUT MAINLY MVFR WITH POCKETS OF IFR WILL LIFT TO MVFR AS DRY SLOT MOVES THROUGH THE AREA WITH SOME EMBEDDED SHOWERS OVER THE NEXT FEW HOURS. WIND GUSTS WILL INCREASE TO UPWARDS OF 40 KTS OVER THE NEXT FEW HOURS AS WELL. WIND SHIFT LAGS COLD FRONT A BIT BUT SHOULD BE PASSING THROUGH THE SITES WITH A SHIFT TO SOUTHWESTERLY AND THEN WESTERLY TO NORTHWESTERLY WINDS WITH GUSTS OVER 40 KTS CONTINUING THROUGH THE NIGHT. CHANGE OVER TO A MIX OF RAIN AND SNOW IS POSSIBLE AT KHUF AND KLAF BEFORE 0Z BUT AFTER THAT SHOULD BE ALL SNOW. HEAVIEST SNOW IS EXPECTED TO START AROUND 2Z AT KHUF AND SPREAD NORTH AND EAST FROM THERE. RIGHT NOW WILL INCLUDE TEMPO FOR LOWER VISBYS WITH THE HEAVIEST SNOW AROUND 2-6Z. SNOW SHOULD LESSEN AFTER THAT AND COME TO AN END AT THE SITES BY AROUND 12Z BUT LOW CEILINGS COULD REMAIN AND WIND GUSTS WILL STILL BE UP AROUND 30 KTS THROUGH 18Z FRIDAY. && .IND WATCHES/WARNINGS/ADVISORIES...

A 47-year-old, semi-tractor-trailer driver from Tennessee was killed in a crash on Interstate 65 in Jackson County, Indiana State Police said. The crash happened about 2:30 AM. Friday in the northbound lanes of I-65 near mile marker 36 when the driver lost control while crossing the icy bridge over U.S. 31, police said. After leaving the roadway, the semi slid down an embankment and struck a concrete barrier. During the impact, the semi's trailer detached and went thought the cab, killing the driver, police said. I-65 was shut down for nearly four hours before reopening.
One to two inches of snow was observed in nearby Lawrence County.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
