- Prolonged lake effect rain and at times snow showers will continue through at least Saturday morning, especially in northwest IN.
- Rain will transition to snow through early this morning, resulting in a few inches of wet, slushy accumulations that will lead to some localized travel impacts. At or above- freezing temperatures are expected to limit the coverage of impacts, however.
- Cooler temperatures are expected through the weekend before temperatures warm next week.
