The risk of dangerous and damaging thunderstorms will continue Thursday night from Detroit and Indianapolis to Memphis and Vicksburg, Miss..

The storms will organize along an advancing cold front pushing eastward from the Plains and swinging into the Mississippi and Ohio valleys to near the upper Gulf Coast. The line of storms, also called a squall line, is over 1,000 miles long.

The most widespread characteristic of the storms will be strong wind gusts, frequent lighting strikes and sudden downpours. Some communities will be hit with downed trees, power outages and flash flooding. People should seek shelter indoors, away from windows as the storms approach. Motorists are reminded to not drive through flooded roadways.

Cities in the path of the storms during Thursday night include: London, Ont., Dayton, Ohio, Bloomington, Ind., Louisville, Ky., Nashville, Tenn., and Jackson, Miss.

However, a few of the strongest storms can bring a brief tornado.

The risk of a few tornadoes is greatest over a zone from southeastern Michigan to the tri-state area of Arkansas, Mississippi and Tennessee.

The area from Indiana, Ohio, Kentucky, southeastern Michigan to southwestern Ontario appear to have an elevated risk of damaging wind gusts for a time Thursday night. This potential for high winds would reach into western New York state, western Pennsylvania and the northwestern part of West Virginia Friday morning and midday.

Hail is also a possibility with some of the storms.

The zone of strong to severe thunderstorms will cause slow travel on the highways and can lead to substantial flight delays in the region, rippling to other portions of the nation well outside of the severe weather threat area.

In the wake of the storms flooding of streams and rivers will remain a problem, due to the excessive rain that has occurred from parts of Missouri to Iowa, Illinois, Wisconsin, Indiana and Michigan.

During Friday, the risk of strong to severe thunderstorms will reach the eastern Great Lakes and the Appalachians. By Friday night, the remnants of the storms will reach the Atlantic Seaboard with localized downpours, gusty winds and travel delays at the very least.
