Tornadoes
Tornadoes confirmed by NWS Chicago and their corresponding tracks will be displayed in the dashboard and interactive map below as NWS damage surveys are finalized. Note that any tornadoes that crossed NWS service areas will NOT appear in the below tornado count and table, though they will still appear in the interactive map display. For this event, the Harpster to Elliott EF-0, Ludlow EF-1, and Hebron to Kouts EF-3 tornadoes will NOT appear in the tornado table and count.
Select a tornado from the table to zoom into the track and view more information. The default table view is limited to 8 tracks, but can be scrolled by a mouse wheel or dynamically expanded. Additionally, the table can fill the entire window by clicking the small circular expanding arrow icon at the very top right of the table and returned to its original size by clicking the button again. The side information panel that opens over the map can be closed using the "X" on the upper right corner of the pop-up. Zoom into the map and click damage points to see detailed information and pictures from the surveys.

Meteorology and Environment
 |
 |
 |
| Surface pressure analysis at 6 PM showing a seasonably deep area of low pressure around 1000 mb shifting across southern Wisconsin. | Temperature and dewpoint analysis at 6 PM. Strong south to southeasterly winds were helping push increased moisture northward following widespread morning rain and thunderstorms. | Accompany surface observations at 6 PM. Temperatures jumped around 7-11 degrees in 1-2 hours, and dewpoints additionally surged back into the upper 70s. |
 |
 |
 |
| Winds around 20,000 feet at 6 PM were near 50 knots and steadily increasing with the approach of a robust upper-level disturbance. | Winds around 5,000 feet. These were rapidly increasing, to around 45-50 knots. This rapid increase promoted a considerable uptick in low-level wind shear. | 0-1 km wind shear analysis around 6 PM. Values were increasing through 30-35 knots, which is exceptionally strong and supportive of low-level storm rotation. |
 |
 |
 |
| Significant Tornado Parameter analysis at 6 PM. Values in excess of 5 highlight a volatile environment supportive of general updraft rotation and tornado development. | Violent Tornado Parameter analysis at 6 PM. Values over 8-10 highlight that the parameter space was rapidly becoming supportive of significant tornadoes. | A special 21z (4 PM) upper air sounding from Lincoln, Illinois showing a highly favorable thermodynamic and kinematic environment for severe, rotating thunderstorms. |
