- Showers and thunderstorms possible (15-45%) this afternoon and evening along and north of Interstate 94.
- Small (20%) potential for a shower in far southwest Wisconsin tomorrow evening. Better chance (50-80%) for rain Thursday into Thursday night but impacts are not expected.
- Much colder temperatures (mid-20s to mid-30s) expected on Friday night. This bring an end to the growing season for some, particularly north of I-94 (20-50% chance to fall below 28).
