A string of thunderstorms developed in west Tennessee late Thursday night and some were very strong.

A tornado warning was issued for Henry County for a time Thursday evening. Another line of storms moved into the region just before midnight.

Parts of the area were under a tornado watch Thursday night, but state emergency management officials said Friday morning they've recieved no reports of touchdowns or serious property damage.

In Nashville, police believe a tree was hit by lightning and fell across some power lines. Police closed the road near Old Hickory Boulevard for a time.

Just south of Clarksville, a roof and a trailer that belonged to a business there were damaged. Police said it looks like the damage was caused by the high winds that blew through early Friday morning.

The owner of the business said he could hear the storm coming.

“Got back to the house, and we’d been there for 10 or 15 minutes and all of a sudden, it sounded like a big gust of wind, you know, that whistling sound. I said, ‘It sounds like a tornado is coming through.’ But it didn’t last but just a few minutes, and then I got the call that said our alarm was going off out here at the shop,” said Tim Ashby.

Ashby said he wanted to take precaution because of the memory of the tornado that struck Clarksville.

In Logan County in Kentucky, officials there said a tree was blown into a house.

Tennessee Emergency Management Agency spokesman Jeremy Heidt said there had also been reports of some flooding, but no injuries associated with the storms.

The National Weather Service in Memphis said between 5 p.m. Thursday and 6 a.m. CDT Friday, the area had recieved about 2 inches of rain. Strong storms were expected over northern Mississippi on Friday, but western Tennessee was not expected to see much of that system.

Forecasters in Nashville said some northwestern counties in Middle Tennessee received up 2 1/2 inches of rain between 3:30 p.m. Thursday and 6 a.m. CDT Friday.

Most of Middle Tennessee area will be under slight risk for severe thunderstorms through Friday.

Last week, storms dumped up to four inches of rain in parts of Tennessee, leading to at least four deaths attributed to flooding.
