The episode as NWS LMK wrote it up.
A cold air mass already in place combined with an anomalous low pressure system to produce an early season freezing rain event across southern Indiana and central Kentucky. Many locations received between a tenth and a quarter of an inch of ice accumulation on trees/shrubs and other elevated surfaces. Warm ground temperatures kept most roads ice free, though some bridges had slick spots.
The ice on the trees, many of which still had leaves that helped to weigh them down, caused several limbs/branches to snap and some trees to fall. There were many reports of power flashes overnight as branches hit transformers. At the peak of the event, over 100,000 customers were without power in the region. Some lost power for several days. Out of state crews were brought in to help restore power.
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 Louisville, KY wrote its last area forecast discussion before the first event at Nov 14, 6:57 PM EST, 1 hour 3 minutes earlier.
