SPRINGFIELD, ILLINOIS — Wednesday morning storms across the Midwest are just round one of today’s severe weather threat, with the stronger and more tornado-capable storms still to come this afternoon as a cold front and low pressure system pivot through Illinois and Indiana bringing greater tornado potential than what has already occurred this morning.
Round One Underway But Bigger Threat Arrives This Afternoon
The AguaceroWX Wednesday June 17 graphic shows Round 1 of storm activity circled in red across the Davenport, Ottawa, Springfield, and Indianapolis corridor as the warm front lifts north ahead of the approaching cold front. A 990 millibar low pressure system is positioned near Minneapolis, with the associated cold front extending southwestward as the system pivots toward the Illinois and Indiana region.
The morning storm round is occurring ahead of the primary severe weather window, with forecasters clearly indicating that what residents have seen this morning is not representative of what is coming this afternoon.
Cold Front Pivot Will Drive Stronger Tornado Capable Storms
The pivot of the cold front and low pressure system through the region this afternoon is when the greater tornado potential will materialize across Illinois and Indiana. Cold front interactions with the warm sector instability shown in yellow and green across Kansas, Missouri, and southern Illinois on the AguaceroWX graphic will provide the enhanced fuel needed for stronger storm development.
The instability or storm fuel label visible across the warm sector south of the current storm activity underscores that the atmosphere still has significant energy available for afternoon storm intensification.
Illinois and Indiana Residents Should Not Let Down Their Guard
The critical message for residents across Illinois and Indiana is that the morning storm activity does not represent the worst of Wednesday’s threat. The afternoon window as the cold front and low pressure pivot through the region carries the greater tornado potential and all-hazards severe weather risk that forecasters have been highlighting for days.
Anyone in the outbreak zone should maintain full preparedness through the afternoon and evening hours Wednesday with tornado shelter plans ready to execute on short notice.
