Severe Storms for Minneapolis, Western Great Lakes

Thunderstorms are expected to break out across parts of the Midwest and Great Lakes on Wednesday.

There is a risk for some severe thunderstorms, especially during the afternoon and evening, and those can contain damaging winds, hail and downpours.

With strong thunderstorm winds there will be the threat for damage to trees and property. Power outages can also occur from trees falling on power lines and lightning strikes.

The more intense thunderstorms will also contain downpours that can drop a lot of rain in a short period of time. Where these storms track there will be the threat for flooding of low lying and poor drainage areas.

The threat area includes Minneapolis, Green Bay and Madison in Wisconsin, and Sioux Falls, S.D. Travelers on Interstates 90, 35, 94 and 39 could find themselves in the path of some of these thunderstorms.

Any time roads are wet there is the risk for hydroplaning, especially when driving at highway speeds. Slowing down will lower the risk of that occurring.

Keep in mind it is dangerous to drive through flooded roadways. It is difficult to tell how deep the water is over the road, and it can take as little as 18 to 24 inches of water to lift a vehicle and carry it downstream.

If you come across a flooded road while driving, it is recommended that you turn around and find an alternative route.

Temperatures across the region on Wednesday will be in the upper 80s to low 90s, and it will be rather humid. A cold front moving into this warm and humid air mass is what will help thunderstorms blossom.

This front will move through tonight, and the sticky air mass will be replaced by more comfortable air for Thursday. Highs on Thursday will be in the 70s and 80s with much lower humidity.

However, the break from the heat will be brief, as hot and humid air will return late this weekend and into early next week. High temperatures on Sunday and Monday will be in the 90s for Minneapolis, Des Moines and Omaha.
