The National Weather Service announced for today a series of severe thunderstorms for the southwestern Iowa area. The forecast is also expected to bring powerful winds and significant hail.

Later in the day, thunderstorms and scattered showers will appear over the northeastern Iowa region and isolated storms will also be present in central Iowa.

The flood warnings issued a few days ago will remain in effect all across Iowa, as the recent heavy rains have caused several overflows on the Iowa, Cedar, Wapsipinicon and Maquoketa rivers. The river-areas where people must remain alert due to the flood risk are the Raccoon, South Skunk River, East Fork of the Des Moines, Beaver Creek, the Des Moines River, the North Raccoon River and also some portions of the Little Sioux and Missouri rivers.

Tuesday’s forecast shows a little improvement, with a partially sunny sky, a 50 percent chance for thunderstorms and showers and with the high in the upper 70s. The prognosis appears identical for Wednesday with the same 50 percent chance for bad weather and a partially clear sky.

Meteorologist Justin Lane, of the National Weather Service, called the week's forecast "very summer-like," with more than 10 degrees above the usual temperature for this time period.
