Summary (tl;dr)

Google searches for "severe thunderstorm watch" and "severe thunderstorm warning" are surging as a dangerous, prolonged heat wave across the central and eastern United States provides conditions ripe for scattered severe thunderstorms today, primarily impacting areas from the Plains to the Midwest, Tennessee Valley, and Mid-Atlantic.

Essential Background

The current severe weather outbreak is unfolding against a backdrop of extreme heat and humidity that has gripped much of the central and eastern U.S. for an extended period, leading to numerous record-breaking temperatures and "Extreme Heat Warnings" in regions like Pittsburgh and Alabama. This oppressive heat and moisture in the atmosphere are creating an unstable environment highly conducive to the formation of powerful thunderstorms.

Beyond this core area, isolated to scattered severe storms are also forecast to extend eastward across the Midwest, Tennessee Valley, and Mid-Atlantic regions.

Specific warnings and watches are active across several states. In Illinois, a Severe Thunderstorm Watch covers counties including Cook, Ford, Grundy, Iroquois, Kankakee, Kane, Kendall, La Salle, Livingston, and Will.
