Locally damaging thunderstorms will stretch from the eastern Great Lakes to the southern Plains Thursday night, while drenching thunderstorms will flood some communities in the Southeast.

Thunderstorms rolling eastward Great Lakes and the central Mississippi Valley have had a history of damaging wind gusts.

The storms will reach into southwest Ontario, part of the St. Lawrence Valley and the eastern Ohio Valley overnight into Friday.

As of 7 p.m. EDT Thursday, certain local spots in Michigan and Illinois had reported about 1.5 inches of rain. In Michigan, wind gusts up to 60 mph were reported, with one gust registering at 71 mph in Davison.

In addition to the risk of high winds downing trees and power lines, some locations can be hit with large hail, frequent lightning strikes and flash flooding. Be careful, as the storms have a good forward rate of speed for the midsummer and can sneak up on you quickly.

The tail end of the front progressing over the Midwest is hanging up over the southern Plains. In this area, complexes of thunderstorms that get going through Friday can lead to flash flooding and very localized wind gusts and hail.

The storms will invade parts of New England and the central Appalachians during Friday.

Meanwhile, another stalled front over the Southeast will interact with an upper level feature from the Atlantic Ocean and lingering tropical moisture.

The three systems will continue to make trouble in the form of drenching thunderstorms and locally gusty winds through Friday and into the weekend. There is an elevated risk of flash flooding along the southern Atlantic Seaboard to the eastern and central Gulf coast areas. A handful of the thunderstorms can also produce brief damaging wind gusts.
