Enhanced Risk Severe Weather Threatens Chicago, Madison, Milwaukee, and Rockford This Afternoon With Three Possible Dangerous Outcomes on the Table
CHICAGO, Ill. — The entire area from Cedar Rapids and Dubuque through Madison, Milwaukee, Rockford, and Chicago remains under a Level 3 of 5 Enhanced Risk for severe weather this afternoon and tonight. Forecasters are describing this as a very complicated setup with three distinct potential outcomes — ranging from isolated supercells with tornadoes to a widespread damaging wind event, or both scenarios occurring simultaneously. The cap remains the wild card that will ultimately determine which outcome plays out.
Three Possible Outcomes — All Dangerous
Outcome #1 sees the cap breaking between 4 and 10 PM, triggering isolated to widely scattered supercells capable of very large hail, tornadoes, and gusty winds. This is the most dangerous scenario for the region.
Outcome #2 sees storms failing to fire in the afternoon, with a more organized complex arriving later in the evening bringing widespread gusty winds as the main threat, along with some hail and brief weaker tornadoes.
Outcome #3 — the least likely but not impossible scenario — sees both outcomes occurring back to back, raising additional concerns for localized to potentially widespread flash flooding on top of all other hazards.
Threat Breakdown — Hail, Tornadoes, and Damaging Winds
Large hail carries a 30% probability across the core zone covering Madison, Milwaukee, Dubuque, and Rockford. The tornado risk sits at 10%+ for the same area, dropping to 5% further south toward Davenport and Ottawa. Damaging winds carry a significant 15% probability across the broader corridor, with forecasters labeling the wind threat as significant for the Chicago metro and surrounding communities.
