A line of storms is expected to form later this afternoon into the early evening, progressing east-southeast through the local area into tonight. Main severe threat will be damaging winds of 70+ mph where the line progresses. While highest probability (15-45%) for severe weather extends locally from northeast Iowa into southwest Wisconsin, strong to severe storms remain possible elsewhere across the area with large hail as the secondary hazard. Plan ahead of nighttime storms by ensuring means of receiving warnings will awaken you.
