Environment
Snow developed ahead of an area of low pressure and north of a surface warm front. Plentiful moisture combined strong isentropic lift produced a widespread area of heavy snow. Snow fell starting late Friday night and continued through Saturday night. During the afternoon on Saturday, temperatures slowly climbed above freezing across south central Indiana which led to lower amounts of snow.
