Geen Bay, WI Answer Key

Summary of the Event:

Date of Sounding: 12 May 2000 @ 12 UTC
Much like the Detroit case, a supercell initiated before noon in western Wisconsin, north of a warm front. SBCAPE south of the warm front was over 2000 J/kg, but surface temps in Wisconsin were in the low 50s. The supercell was a hail beast, with very wide swaths of severe hail and several reports of 2.00 to 2.50 inch hail, between 15-16 UTC and just south of Green Bay. The shear amounts of the large hail combined with severe winds did tremendous damage across central and eastern Wisconsin, making it one of the costliest storms ever to hit Wisconsin.
