Showers and a few thunderstorms will become more widespread Sunday night. Those will hang around off-and-on into Monday. Locally heavy rain is possible in northern Iowa. In the afternoon, an area of low pressure will scoot across the heart of eastern Iowa. Ahead of it, mainly south of Interstate 80, highs should be in the 70s. However, north of it, highs will be limited to the 60s and even 50s, with northern Iowa being the coolest. Some of the storms late in the afternoon could be strong, mainly east of the Cedar Rapids/Iowa City area.
Our chance of rain comes down Tuesday and part of Wednesday. Midweek looks mild and breezy ahead of the next weather system that brings additional storms mostly late Wednesday into Wednesday night.
A series of weather systems thereafter will keep us in the risk of rain pretty much every single day through early next week. We will once again have to watch river levels.
