The temperature never rose above freezing across these areas, which allowed ice to accumulate to between a half-inch and an inch. This resulted in significant tree damage and numerous power outages.
The intensifying storm caused the pressure gradient to tighten across western and northern Ohio and resulted in very strong winds with gusts up to 45 mph. This caused significant blowing and drifting of snow across areas from Troy to Marysville, and farther north into Celina, Wapakoneta and Bellefontaine.
As a result, road crews had a very difficult time keeping roads clear. By Tuesday afternoon, travel across west central Ohio was nearly impossible.
By Tuesday evening, a Level 3 snow emergency had been declared in many counties in west central Ohio. The snow continued late Tuesday night, and by Wednesday morning had accumulated from 8 to 15 inches.
The wind caused snow to drift substantially. In some cases, drifts were more than 4 feet high.
