The episode as NWS ILN wrote it up.
Strong low pressure at the surface tracked towards West Virginia. At the same time, a strong upper level low pressure system strengthened as it crossed east through Kentucky. The combination of the two and an onslaught of colder air brought significant snow accumulations to areas east of Wilmington, Ohio, with light accumulations found along and west of the I-75 corridor.
