Much of central and southern Indiana continues to be have a slight risk of severe thunderstorms tomorrow, according to the Day 2 Convective Outlook that the National Weather Service Storm Prediction Center issued at 1:49 a.m. today. The greatest risks are for damaging straight-line wind gusts and severe hail produced by lines of storms in the late afternoon and early evening tomorrow.
As you can see on the map above right, the slight risk area includes most of the western half of Indiana, with the exception of some northern counties. The slight risk area includes the cities of Logansport, Marion, Kokomo, Lafayette, Indianapolis, Terre Haute, Bloomington, Evansville and others. Its northern edge includes all or significant parts of the following counties: Benton, White, Cass, southern Miami, southern Wabash and extreme southwestern Huntington.
The SPC will update its day two outlook for this period by 1:30 p.m. EDT. After that, our next outlook for Friday will arrive with the first day one outlook at around 1 a.m.
Meanwhile, northern Iowa and southern Minnesota is in a bull’s eye for severe weather today, where the SPC is forecasting supercell thunderstorms this afternoon. Forecasters expect tornadoes — some of which could be strong — as well as large, damaging hail and sporadic severe straight-line wind gusts in that area. This moderate risk area for today runs from just south of Minneapolis south to and including Des Moines.
