Since this morning, the threat for severe weather has increased, especially over eastern Iowa. As you can see in the graphic to the left, most of the state is now under a slight risk for severe weather. The atmosphere is very unstable and an atmospheric cap is expected to lose its grip on much of the state later this afternoon.
Already, showers and thunderstorms have developed in portions of southern and western Iowa. These storms have stayed well below severe limits but could be a precursor to additional development tonight.
As you can see in the graphic to the right, the risk for tornadoes has increased slightly in portions of eastern Iowa. This threat is for later this afternoon as new development could take shape over this area. We are closely monitoring these trends and will continue to bring you updates as needed. If the weather warrants we’ll launch our live coverage later this afternoon.
