Here’s the map for possible snow accumulations Tuesday night into very early Wednesday mroning. Don’t see much reason to fiddle or futz with the ongoing forecast after doing some research just now. Changeover is still likely to happen starting late afternoon in the west part of Indiana and then moving east across the state through early evening. Wet snow should end very early Wednesday morn.
The snow will follow sometimes-heavy rain on Tuesday. A Flood Watch is in place for most of the state through Tuesday evening.
