Concurrently, a Heat Advisory was issued through 9 p. m.
Monday, July 27, 2026, for parts of the Midwest as temperatures climbed into the 90s with heat index values between 100 and 105.
Severe scattered storms containing heavy rain, lightning, and damaging wind gusts are anticipated to follow the extreme heat.
Climate experts have connected the increasing frequency of these severe weather events to broader atmospheric shifts driven by rising greenhouse gases.
"We are experiencing exactly what the climate models in the 1990s said we should experience now.
That is more frequent, more severe heat waves, bigger temperature anomalies, more humidity, higher overnight temperatures," said Andy Pershing, chief program officer at Climate Central.
Pershing clarified that these intensifying patterns are directly tied to the unfolding global climate narrative.

While the central and southern regions face extreme conditions, the Mid-Atlantic, Northeast, and Pacific Northwest are expected to escape the worst of the heat dome.
