A potent weather system arrives for Friday that will affect the entire Upper Midwest, with the risk for severe weather being the main threat locally. A line of storms is expected to develop over central Iowa Friday mid-afternoon and race northeastward, potentially bringing damaging winds. An isolated tornado cannot be ruled out as the line of storms progresses northeast. The storms should weaken as they move north of the I-90 corridor in the early overnight hours.

Prepare now for severe storm potential by checking your emergency supplies and having plans for safe places, communication, and evacuation. With the first storm potential of the year, make sure your phone can receive wireless alerts.
