Late January freezing rain event not considered an ice storm

FORT WAYNE, Ind. (WANE) – Freezing rain has been impacting our Monday and will continue into Tuesday morning across northeast Indiana and northwest Ohio. While roadways are slick, this is not a severe enough freezing rain event to be called an ‘Ice Storm.’

Here’s how air temperature determines the type of precipitation we see at the surface

This is because we are forecasting less than a quarter of an inch of ice accumulation. This is enough ice to cause slick travel and prompt a Winter Weather Advisory, but not an Ice Storm Warning. Below is the criteria needed in order for a Winter Weather Advisory to be issued.
Ice accumulations less than 0.25″ will prompt a Winter Weather Advisory.

The last time we dealt with widespread freezing rain of the magnitude we are seeing with this event was back on New Year’s Day in 2021. We saw ice accumulations of two-tenths of an inch or less across the area, which is what we expect to be the outcome of this freezing rain event. We saw ice coat trees and cars, but not cause significant impacts.
