Models show 1 to 2 inches of rainfall. Low res 06zNAM was the most aggressive bringing 2" to northern Wisconsin. It's at odds with the high res NAM that brings heaviest rains into southern WI. I've taken a broad approach with a GFS/EC blend. The impact overall appears low so I'm not pushing out alerts right now.
THUNDERSTORMS - Three factors contributing to a low severe threat atm:
1. Timing is unfavorable. AM/morning.
2. Cloud cover.
3. Rain & Debris. Too much clutter to allow for destabilization suppressing the boundary layer.
If timing slowed down then perhaps a severe threat might emerge for Sunday afternoon in far southern WI/Illinois.
