Overview
- The Storm Prediction Center issued a Level 2 “slight” risk for the Chicago region on Friday, with the primary severe window forecast from mid‑afternoon into late evening and main storms expected around 7–10 p.m.
- Forecasters say the main hazards are damaging straight‑line winds, large hail, heavy rainfall and a small chance of an isolated tornado, and they stress that storms will be scattered rather than widespread.
- Meteorologists expect initial development near the Wisconsin border around midday that could move south into the Chicago area, with storm placement and timing remaining uncertain so real‑time warnings are important.
- Officials urge people at outdoor events to seek immediate shelter if they hear thunder and recommend waiting in cars as a safer short‑term option until storms pass.
- Northwest Indiana remains vulnerable with tens of thousands still without power and local emergency declarations in place, which could increase danger and complicate recovery if severe cells strike outage‑affected areas.
