Partly cloudy skies are expected Monday night with dry conditions. Lows are expected to fall into the 50s. Clouds increase Tuesday with rain/storm chances returning Tuesday night. Rain is expected to continue throughout the day Wednesday.
It has been a near-record month for rainfall across Iowa, and it will end with more widespread and potentially heavy rain around the middle of this week. Showers and thunderstorms will move into western Iowa on Tuesday, then persist in a swath that will slowly move across most of the state for a couple of days before finally exiting. The most likely period of heavy rainfall will occur from late Tuesday night into early Thursday, or perhaps even into late Thursday. Total rainfall amounts during this time will be 2 - 4 inches or greater in some areas, resulting in renewed flooding concerns. Be sure to stay tuned to the latest forecasts, and possible watches and warnings, as the week progresses.
