Forecast from FOX6 Chief Meteorologist Rob Haswell

MILWAUKEE - Dense Fog Advisory in place until 9a Friday for all of SE Wisconsin. A Flood Watch is in place until 1pm on Saturday for all of SE Wisconsin.
We start off quiet but messy, with dense fog , then all eyes turn to Friday afternoon and evening, when the atmosphere really loads up for more strong to severe storms across Wisconsin.
There are a lot of moving parts here, but the setup supports everything from large hail and damaging winds to a few tornadoes, especially if storms can stay more isolated early on.
Heavy rain is also part of the story, with flooding concerns ramping up into Friday night as multiple rounds of storms move through. Behind it all, we flip the switch to a cooler and quieter for the weekend.
