ORIGINAL STORY: A severe thunderstorm warning was issued for northwestern Cobb, northeastern Paulding, southwestern Cherokee and southern Bartow counties Friday.

Expect large hail, damaging winds and lightning through 2 p.m., according to the National Weather Service.

Storms could bring 60 mph wind gusts and hail the size of half dollar coins.

“For your protection, move to an interior room on the lowest floor of a building,” the weather service said.

The warning didn’t extend to Fulton County, but Channel 2 Action News meteorologists said residents can expect lightning, heavy downpours and possible hail to slow down the afternoon rush hour.

Hail had already started falling north of Cassville as of 1:10 p.m.

“So if you head out to the pool today and you hear that rumble of thunder, get into the house and wait at least 30 minutes until you have not heard thunder anymore,” meteorologist Karen Minton said.

Heavier downpours will last through 4 p.m. and calm some by 5 p.m.

“It may have to be an evening pool time because [rain’s] sticking with us through the rush hour,” Minton said.

Rain will taper off by 6 p.m. and weather conditions in metro Atlanta will improve.

“And by improvement, I mean lower humidity,” Minton said. “We get a break from it for a couple of days.”

Highs will stay in the low to mid-80s this weekend.

Temperatures were 93 degrees in Atlanta, 81 degrees in Blairsville and 92 degrees in Griffin just before 1:40 p.m.

In southeast Georgia, where a heat advisory is in effect through 6 p.m., the heat index could reach 108 degrees.

"High temperatures and humidity could lead to heat illnesses if proper precautions are not taken," according to the weather advisory.
