Storms roll into Chicago as summer heat cranks up the danger

Heavy Rain, Damaging Winds, and Brief Tornado Risk Expected

A fast-moving storm front is set to slash through the Chicago area starting Wednesday afternoon, bringing heavy rain pockets and gusty winds that could knock over weak structures.

Timing & Impact Zones

• Peak danger hits western suburbs first (Joliet, Cresthill, Shorewood) around 3:00 PM.
• Wind speeds could reach 60–75 mph, while rainfall may total up to three-quarter-inch.
• Brief tornado warning was issued for Joliet, Cresthill, and Shorewood just after 3:20 PM, but forecasters now expect straight-line winds—capable of flattening sheds, ripping roofs, and toppling trees onto roads.

Storm Speed & Safety

• The system is moving at 45 mph, meaning rain won’t linger long enough to flood basements.
• Flying debris makes staying indoors the smartest move.
• Power crews are prepped—ComEd teams are staged to restore power quickly after damage is assessed.

Thursday’s Storm: A Potentially Stronger Threat

The real challenge arrives Thursday, fueled by sticky 89-degree air—a "jet fuel" for thunderstorms.

• Forecasters warn of even stronger gusts and a risk of actual tornadoes.

Safety Reminder

If skies rumble, head indoors immediately and stay inside for 30 minutes after the last thunderclap.

Stay alert—Chicago’s weather is about to get rough.
