What a cool thing to see after returning from the Plains! Numerous pulse-severe thunderstorms are exploding across the Chicago Metro, SE Wisconsin, and NW Indiana. Low dewpoint depressions, SBCAPE on the order of up to 4500 J/kg, and a non-existent capping inversion have set things in motion this afternoon. If only there was favorable wind shear and a stronger cap, sincethose seem to be the only thing missing from this equation. Nonetheless, many warnings have been issued for hail and wind from these rock-hard photogenic, but short-lived updrafts.
