Multi-Day Severe Weather Threat for Midwest, Ohio Valley

A multi-day severe weather event will unfold Wednesday and Thursday across the Midwest and Ohio Valley, respectively.

Thunderstorm development is expected over southern Minnesota, northern Iowa, and eastern Nebraska by Wednesday evening, with the most intense convection being simulated over northwest Iowa. The image above shows forecasted radar reflectivity over the Midwest area at 7PM Wednesday. In other words, this is what one forecast model thinks the radars will see unfolding at 7PM Wednesday. If it does verify, this could be a rather intense severe weather event for anyone caught in the line of fire of a particularly nasty line segment of storms, such as the one shows in northwest Iowa.

The primary threats here will be damaging winds and hail; the linear shape of these storms should cut down on the tornado threat.

By Thursday afternoon, thunderstorm development is renewed in Indiana, Michigan, Kentucky, and Ohio. These cells should be more individualized, raising the hail and tornado threats, but still keeping the tornado threat at a rather low level.
