Severe thunderstorms are expected from late evening into the early morning hours of Monday across the upper Midwest, particularly across central and southern Minnesota, northeast Iowa, southwest Wisconsin and northwest Illinois.
Storms will be developing late afternoon across western Minnesota and will grow upscale into a line as it propagates to the southeast into Iowa and Illinois. Storms initially will be isolated, and will pose a large hail and isolated tornado threat across southern Minnesota. After a couple hours, storms will then merge into a bowing segment, which will then track to the southeast across northeast Iowa and northwest Illinois.
As this line enters Iowa and Illinois, the primary treat will be damaging wind gusts up to 70-mph. Large hail will also be possible, but this will be a secondary threat. Heavy rain will also be possible with these storms, so flash flooding will also be a concern.
Additional severe weather is expected in these same areas on Monday and Tuesday. Continue to follow WeatherNation on-air and online for the latest severe weather updates.
