As metro Atlantans recovered from the damage of Tuesday's thunderstorms, more storms moved through the area Wednesday night.

The storms are marked by heavy rainfall, tremendous lightning and wind gusts, Channel 2 Action News meteorologist David Chandley said.

The National Weather Service issued a severe thunderstorm warning for Cobb County that expired at 10:30 p.m.

Georgia Power reported that 2,900 metro customers and nearly 3,900 statewide were without power around 11 p.m., Channel 2 said.

The storms threatened to bring a repeat of the heavy downpours, hail, lightning and high winds that wreaked havoc across much of north Georgia and metro Atlanta the night before.

Tuesday night, thousands of lightning strikes were counted across metro Atlanta's northern arc, and strong winds blew down trees in Cobb County and north Fulton County, where a tree was dropped on Barbara Golsen's Sandy Springs home.

"I've had lots of trees down in the 45 years, but not into my house," the septuagenarian Golsen told the Atlanta Journal-Constitution. "What are you going to do when wind comes through?"

She said her home was also pelted by hail.

"The hail last night into the pool was about as big as I've ever seen," Golsen said.

Joel Blackford said the flash storm pummeled his Sandy Springs home with hail, driving rain, and eventually a tree branch through his skylight.

"We had last night one of the most violent microstorms," Blackford said. "There was a period of five minutes where the rain was actually horizontal. It was like you had pulled a curtain down."

Both Blackford's and Golsen's homes were among the roughly 10,000 metro Atlanta homes Georgia Power reported were without power at the height of the storms Tuesday night.

"We're not out of the danger zone for severe weather," said Kirk Mellish, meteorologist for News Talk Radio WSB AM 75 and now 95.5 FM.

But the upside of the severe weather, forecasters say, is cooler weather.

Highs are expected to be in the mid 80s Thursday and Friday, with lows in the low 70s.

But more rain is in the forecast.

There's an 80 percent chance of rain Thursday and a 60 percent chance Friday, Chandley said.
