DES MOINES, Iowa —

Interactive Radar | Weather Alerts | Skycams

The Flood Watch and flash flooding potential will persist into Saturday and potentially into Sunday.

Storms producing heavy rainfall rates of 1 to 2 inches per hour will be possible and could lead to 1 to 3 inches or more in some areas. Flash flooding and river and creek flooding could become more of an issue across parts of the state, especially central and southern Iowa.

We will finally catch a break as a ridge of high pressure takes over at the start of next week. The dry weather will not last long, with more storm chances returning midweek.

Iowa weather forecast:

Today: Overnight storms last into the morning, then partly to mostly cloudy skies. More scattered rain expected during the afternoon. High 81F. Winds SE at 10 to 20 mph.

Tonight: More overnight showers and thunderstorms. Low 72F. Winds ESE at 5 to 10 mph.

Tomorrow: Thunderstorms possible early, then mostly sunny, hotter, and humid. Heat index near 100F. High near 88F. Winds NW at 5 to 10 mph.

Tomorrow Night: Scattered showers and thunderstorms. Low 72F. Winds NNW at 5 to 10 mph.
