... Patchy frost possible tonight...

Low temperatures late tonight will fall into the middle to upper 30s
well inland away from the warming influence of Lake Superior. Patchy
frost is possible well inland away from Lake Superior. Any frost that
does form will not last very long.

If you have any sensitive plants outside that are susceptible to
frost... spraying them down with water or covering them tonight would help
protect them from frost damage.
