A new severe weather outlook yields no change in the threat facing Iowa. Basically the entire state faces a slight risk for severe weather over the next 12-15 hours. Storms should begin developing, especially in southwest Iowa and move through the state during the evening and overnight hours.
Large hail and strong damaging winds are the primary threats, but an isolated tornado or two, especially before sunset, cannot be ruled out. Storms should linger through the nighttime hours. How long the risk for severe weather will last tonight is unclear.
We anticipate some new information to come in from the Storm Prediction Center within the next hour or two. By then we could get an indication of if and/or when we’ll see a Severe Thunderstorm Watch posted for parts of Iowa. We’ll keep track of the latest developments and pass them along to you. We also plan to launch our live online severe weather coverage later today should conditions warrant.
