Overview
A significant winter storm impacted southern Indiana and portions of central Kentucky on March 20-21, 2018. As low pressure developed and pivoted east of central Kentucky Tuesday night, a deformation band of snow also pivoted across the region. The heaviest and most persistent moderate snowfall occurred over southern Indiana and portions of north-central Kentucky, where 5 to 10 inches of snow fell. The heavy, wet nature of the snow resulted in some downed trees and power lines.
