In this jam-packed episode of The ISO bar, meteorologists Rob Haswell (Milwaukee), JD Rudd (Chicago), and Rich Lutermann (Detroit) break down a record-smashing start to the summer season. The team dives deep into the jaw-dropping tornado statistics making Illinois the country's new "tornado alley," alongside massive storm counts in neighboring Indiana. The conversation shifts from violent winds to overwhelming waters, exploring the infrastructure-testing flash floods in Green Bay and the Midwest. The team also shares vital safety reminders regarding the deceptively cold Great Lakes, rip currents, and recent water rescues. Finally, the meteorologists unpack the relentless heatwave locking down the region—touching on triple-digit heat index values, urban cooling centers, infrastructure challenges in Europe , heat hydration breaks at the World Cup , and the infamous Midwest phenomenon known as "corn sweat."
