Officials say Iowans should be prepared for more severe weather today. The storm system that brought at least three tornadoes to central Iowa last night is still parked over the Hawkeye State. Parts of northern Iowa are seeing more heavy rain, high winds and hail this morning. Rick Arkell is a meteorologist at the National Weather Service office in Davenport. He says all of Iowa is in a “threat zone” right now which means there’s a risk of severe weather. Arkell says the zone covers all of Iowa, in addition to parts of Illinois, Wisconsin, Nebraska and South Dakota.Arkell says the same storm front that brought twisters, hail and up to four inches of rain to parts of central Iowa last night is still hovering, as is the risk for more severe weather.
