"Assessing the Impact of Freezing Rain on Travel in Late January"

The freezing rain event in northeast Indiana and northwest Ohio is not considered an ice storm as it is forecasted to result in less than a quarter of an inch of ice accumulation, prompting a Winter Weather Advisory but not an Ice Storm Warning. The last similar event occurred on New Year's Day in 2021, with ice accumulations of two-tenths of an inch or less. An Ice Storm Warning is issued for ice accumulations of a quarter of an inch or more, which can severely impact travel and cause power outages. The most extreme recent ice storm in the area occurred on December 19th, 2008, resulting in widespread power outages and tree damage due to a half an inch of ice accumulation.
