More rain poured into the metro area Friday night, but the second round of storms were not expected to be as severe as those that hit earlier in the day.

Weekend weather forecasts predict rain Saturday and Sunday, with the potential for storms both days.

Seven people working on a Cobb County home were shocked by lightning Friday afternoon as powerful storms rolled through the metro area, bringing down trees and power lines and making a mess of some roadways.

The workers went inside the home on Silver Mist Circle in Powder Springs during the storm, but the frame of the home was hit, injuring all seven, according to Channel 2 Action News. Four people were treated at the scene and three were transported to the hospital for evaluation.

The National Weather Service issued temporary tornado warnings for both Cobb and Cherokee counties, but both expired by 3 p.m. There were reports throughout the metro area of downed trees and power lines, as well as structural damage from the storms. Check the latest forecast here.

Severe thunderstorm warning were issued for several metro counties, and the evening commute was slower due to wet roads. Around 4 p.m., Georgia Power reported about 40,000 outages. At 10 p.m., about 4,700 customers were without power in the metro area, according to the utility's outage map.

The storms rolled into the north metro counties as schools were preparing for dismissal. In Cobb County, some school buses were delayed until conditions cleared, a school district spokesman said. All after-school activities were cancelled in Atlanta Public Schools.

Also in Atlanta, the weather was believe responsible for a roof collapse at a warehouse on Empire Boulevard. No injuries were reported.

In DeKalb County, storms damaged the roof of the Recorders Court, which handles code and traffic violations, among other things. Recorders Court will be closed Monday for repairs, a county spokesman said.

Also in DeKalb, a home caught fire Friday afternoon and was destroyed as the afternoon storm rolled through the Stone Mountain area. It is suspected that lightning struck the Gledhill Way home, according to Capt. Eric Jackson, DeKalb County fire department spokesman.

A tree landed on a car around 3:30 p.m. on River Drive near Lawrenceville in front of Five Forks Middle School, Capt. Tommy Rutledge with the Gwinnett County fire department said. The driver was able to get out of the car and was not injured, Rutledge said.

In Snellville, a large oak tree landed on a Colony Oaks Drive house and lightning possibly sparked a house fire at Lilburn home, Rutledge said. No injuries were reported in either incident.

Flooding was reported at Hartsfield-Jackson International Airport, where three of the four inner traffic lanes at the North Terminal were temporarily closed. South Terminal roadways were not affected.
