Little change in the weather is expected into Thursday with another cool night tonight. Overnight lows are expected to reach the upper 20s to middle 30s leading to frost or freezing temperatures where conditions are favorable. Frost and temperatures at or below freezing are mostly likely to occur where skies have cleared and winds are light. If you have tender or sensitive vegetation, which is most likely over southern Iowa so far this season, you may wish to take protective actions such as covering it with a blanket.
