Low pressure center will track straight through Wisconsin which tends to bring a period of weaker wind gusts during the peak of the event. For Wisconsin as a whole the strongest wind gusts will be on Wednesday during the day and evening as the storm pulls away, possibly gusts to 40-45 mph out of the northwest. Otherwise strong winds gusts will impact the entire region with the highest gusts across Illinois, Indiana, and Michigan.
