After a beautiful day across the state Friday, severe weather will be returning to our forecast by Saturday afternoon. If you have outdoor plans Saturday afternoon or evening, you will want to keep an eye on the weather. A cold front will be moving across the state Saturday evening, which will trigger thunderstorm development.
Storms will form across northwest Iowa, mainly after 3pm, and will advance off to the southeast. Storms will quickly grow into a linear segment, which will create for a damaging wind threat. Some of these storms will also have large hail, up to half dollar size, but the predominant threat will be damaging winds. As storms push to the southeast Saturday evening, they will begin to lose their severity.
Heavy rainfall is expected from this line of storms across the state. The heaviest of the rain fall fall across southwest Iowa, and this is where 2 to 2.5 inches of rainfall will be possible.
