A tornado watch is in effect for Benton, Cedar, Iowa, Johnson, Keokuk, Linn, Tama and Washington counties until midnight.
Tonight: Strong to severe thunderstorms are possible beginning around 6:00 p.m. and ending around 1:00 a.m. tomorrow morning. The biggest area of concern is in our far southern regions, especially Iowa, Johnson, Keokuk and Washington County. However, severe weather is still possible up to Highway 20. The main threat here is potentially very large hail, but we could also see damaging wind gusts and a tornado which could be strong. Stay tuned for the weather tonight and stay up to date on KWWL, as well as our social media pages.
