Approximately the northern two thirds of Indiana has a slight risk of severe weather between 8 a.m. EDT Wednesday, Sep. 10 and 8 a.m. EDT Thursday, according to a “Day 4-8 Convective Outlook” issued by the National Weather Service Storm Prediction Center at 5 a.m. EDT today. The risk area includes portions of other states near Indiana and all 37 counties of the northern Indiana NWS office’s county warning area (and therefore all of IMO SKYWARN’s quadrants).

Forecast conditions indicate “an increasing potential for a regional severe weather event,” which could include supercells and the evolution of an organized thunderstorm system, “accompanied by the risk for damaging wind gusts and a few tornadoes,” according to the SPC outlook.

The SPC will next update its outlook for the period by 5 a.m. EDT tomorrow.
