Storm threat in SE Wisconsin
What we know:
The Storm Prediction Center has southwest Wisconsin under an enhanced risk, which is level 3 out of 5. There is the potential for large hail, damaging winds, and tornadoes. Wind gusts could be as high as 70 mph. The line of storms will be moving fast, therefore flooding is not expected. Large hail over 2" and a strong tornado cannot be ruled out.
The storms will begin to develop in southwest Wisconsin between 2 p.m. and 4 Pp.m., which is peak heating time.

The warming of the atmosphere will help create an unstable environment. As storms continue to migrate eastward, the storms could intensify. The peak intensity timing will be anywhere from 4 p.m. to 8 p.m.
The highest confidence in storms will be north of I-94. However, we can't rule out isolated intense storms for areas south of I-94.
Another thing to factor in is the lake breeze and what that will do for the lakeside areas. The lake breeze could spin up a brief tornado along the lake. The lake breeze acts as its own boundary. Once the storms pass the lake breeze boundary, the storms could weaken as they interacts with the cooler air.
The storms should be out of the area by 9 p.m., leaving mostly clear skies for the night.
