What happened
The episode as NWS ILN wrote it up.
A low pressure system tracked from the southern plains into the northern Tennessee and southern Ohio valleys during the overnight hours of Monday, March 20th. A wintery mix occurred over the Cincinnati metro area with heaviest snowfall occurring in southeast Indiana. Over portions of southcentral Ohio, freezing rain accumulated to a quarter inch. The system tracked quickly through the area and snowfall turned off from west to east on the afternoon of Tuesday, March 21st. Due to the brunt of the system striking the metropolitan area during rush hour...significant delays occurred in the tri-state area.
