(Radio Iowa) – National Weather Service forecasters say severe weather is possible late this (Monday) afternoon and tonight for wide areas of Iowa, including thunderstorms, hail and high winds. Meteorologist Donna Dubberke says those dry parts of the state have a good chance of getting soaked.

Up to three inches of rainfall is possible in some areas through tomorrow, bringing the chance of flash flooding, including the Interstate 80 corridor and south.

For Iowans who have outdoor plans for the Memorial Day weekend, that chance of rain is for late Saturday and much of Sunday.
