SE MN Still in Pothole Country | Several years ago I was spraying Liberty. A fast pop-up thundershower came along. Anything that had an hour before rain was fine. The closer to getting rained on you could see control go downhill. As I remember still killed most broad leaf weeds up till the rain. I would guess you are OK. Most companies are good about replacing product if you need to respray. Realize respraying is a &^%$# this year due to many factors. That was spraying mid-day. Liberty should have a couple of hours of sunshine after spraying. Too close to dark may cause more problems than rain after an hour.
