Heavy Rain Threat Tonight in Northern Iowa

Storms Possible Early, then Warm & Humid Weekend

Moderate to heavy rain is likely to develop overnight across northern Iowa. Those traveling should expect the potential for hydroplaning and low visibility from the rain as well as the potential for localized flash flooding. Rainfall amounts of 1 to 1.5" are possible along the Minnesota border by Wednesday morning. The rain is expected to move off by mid-morning Wednesday.

The Memorial Day weekend outlook calls for a chance of showers and thunderstorms late Friday afternoon or evening, but the remain of the holiday should be generally dry with little if any precipitation. The main weather story will be continued warm and humid weather with persistent highs 85 to 90 degrees and peak heat indices several degrees higher. This will be the first prolonged heat episode of the season so those planning outdoor events should stay hydrated, take breaks and use sunscreen as needed.
