A few severe thunderstorms are possible Sunday afternoon across the Upper Midwest region. A cluster of thunderstorms are expected to develop after sunset Sunday across southern Minnesota, and this cluster will track to the southeast through northeast Iowa.
Thunderstorms will begin to enter northern Iowa as early as 10pm, and will continue to track southeast. Initially storms will pose a large hail threat across southern Minnesota and northern Iowa, but as storms begin to merge, the threat will transition to a damaging wind threat. Heavy rain will also be likely with these storms. Rainfall totals Sunday evening could range from 1 to 2 inches.
On Monday, the severe will exist for much of the state of Iowa. As of Sunday morning, it is only a marginal risk of severe weather, but areas of this outlook are likely to be upgraded within the next 24 hours. Primary threats with this round of severe weather on Monday will be large hail and damaging wind gusts.
