Midwest and Ohio Valley brace for more storms after deadly derecho, dangerous flash flooding

After a deadly derecho and catastrophic flooding battered the Midwest, the relentless weather pattern isn’t letting up, with more severe storms and flooding possible in the days ahead.

This week has been nothing short of extreme across the Midwest and Ohio Valley, and it's barely halfway over.

A deadly derecho, catastrophic flooding and more than one million customers left without power were just the beginning, as more rounds of severe weather threaten the region and much of the eastern U.S.

After rounds of powerful severe storms swept through the region Monday into Tuesday, a widespread flood threat followed Wednesday, swamping parts of Indiana as the FOX Forecast Center warns the active weather pattern isn't over yet.

On Thursday, a Level 1 out of 5 severe storm threat stretches from the Central Plains into the Midwest and southern Ohio Valley, including parts of Iowa, Missouri, Illinois, Kentucky and already-inundated Indiana.

Damaging wind gusts will be the primary threat from any severe thunderstorms that develop.

While severe weather will be a concern Thursday, flooding will pose an additional threat across the region through Friday morning.

Repeated rounds of heavy rain will become a major concern, especially where storms repeatedly track over the same locations.

Flood Watches are in place across portions of Indiana, Ohio, West Virginia, northeast Kentucky, western Virginia, Pennsylvania, North Carolina and east Tennessee.

Portions of the region carry a Level 2 out of 4 flash flood risk through Friday morning and includes major cities such as Chicago, Cincinnati and Pittsburgh.

According to the FOX Forecast Center, widespread rainfall totals of 1 to 2 inches are likely, with locally 2 to 3 inches or more possible.

The FOX Forecast Center said Tuesday's storms were confirmed to be a derecho. In order to be classified as a derecho, a storm needs to stretch at least 250 miles long and be at least 60 miles wide.

At its peak, Illinois, Indiana and Ohio all had over 300,000 customers without power each, while Kentucky was also impacted enough to knock out power to over 100,000 customers.

The strongest wind reports were concentrated across northeastern Illinois and the Chicago area, with several gusts approaching 100 mph through midday Tuesday. Sugar Grove recorded the highest gust at 97 mph, followed by Shorewood at 96 mph, while Bradley and Mokena each reported gusts of 91 mph.

Damaging winds swept into Illinois, triggering Tornado Warnings across several areas Tuesday afternoon — including Aurora, Joliet, Naperville and downtown Chicago.

Flash Flood Emergencies

Torrential rain prompted the National Weather Service (NWS) to issue several Flash Flood Emergencies for life-threatening flash flooding across east-central Indiana late Wednesday morning.

The NWS also issued Flash Flood Emergencies in Indiana in parts of Delaware, Fayette, Union, Wayne and Franklin counties Wednesday, with some remaining in effect through the afternoon.

Some of the highest rainfall totals since Monday have been reported across Indiana and Ohio, where several locations have received more than half a foot of rain.
