The wider storm
One of the bigger tornado events for southern WI over the past 10-15 years with 2 EF-2s occurring and 8 tornadoes in total. Juneau and Mayville took the brunt of the two strong tornadoes, while hundreds of large hail reports and several damaging wind reports were received across southern WI. A strong cold front, extending from strong low pressure over eastern North Dakota, combined with very unstable air and strong wind shear to bring widespread severe thunderstorms to the region.
Began near Portage (43.5175, -89.5009).
