June has started off very wet, with multiple flash flood warnings in mid-Missouri. Columbia firefighters participated in two water rescues on Monday morning.

What’s next: While the ground in Columbia and across mid-Missouri is saturated, we’ll see some dry time this week. Chief meteorologist Jessica Hafner at our news partner ABC-17 says Tuesday, Wednesday and Thursday are expected to remain dry. Rain is expected to return on Friday.
