The August 11 Midday Tornado: What We Know
Just before 11:00 a.m. CDT, Doppler radar detected a strong rotational signature, prompting emergency alerts across Cook and Will counties. Because the system was embedded in heavy precipitation (rain-wrapped), spotting the funnel was incredibly difficult. Relying on radar data was crucial for saving lives.
