Widespread Severe Weather Likely Tonight and Friday

A very moist, warm and unstable atmosphere is setting a ticking time bomb ready to explode with widespread severe weather across much of the Upper Mississippi Valley and Midwest through Friday.

Intense supercell thunderstorms are expected to develop across Nebraska, South Dakota and Iowa Thursday afternoon/evening. Initially, the storms main threat will be damaging winds, large hail and a few tornadoes. As time passes through the overnight, it is expected that the storms will merge together forming a large complex of thunderstorms. The complex will then shift southeastward through the overnight and into Friday morning. The front edge of the complex may "bow" setting up the potential for widespread wind damage. The highest risk for this occurring would be across eastern Iowa, southern Wisconsin, northern Illinois and northern Indiana.

On Friday, the possibility exists that the complex of storms from Thursday night could continue to propagate east-southeast into the lower Great Lakes and Ohio Valley through Friday morning. Otherwise, additional strong to severe thunderstorms are expected to develop across much of the Midwest and Ohio Valleys during the afternoon and evening hours as the environment will remain primed.

I strongly encourage you to monitor local news and NOAA weather radio for the latest advisories and warnings if you live or plan on traveling through the above mentioned areas. I also recommend subscribing to Weather Call, a personal alert service that notifies you of dangerous storms and tornadoes for your specific location.
