Beginning at 1 p.m., heavier showers and thunderstorms are expected to begin developing across Lumpkin County and over toward Rabun County.
Showers are also expected to begin popping up around 2 p.m. in Gwinnett, DeKalb, Spalding and Coweta counties and the surrounding areas.
"There will be a little break here or there, but there may be some heavier spots. You'll need to watch for those because they'll have a lot of lightning, strong winds and real heavy downpours through 6 p.m.," said Minton.
Minton said the evening rush hour will probably be a messy one due to the storms.
Around 8 p.m., thunderstorms are expected in the western suburbs.
"And it will break up as we go overnight," said Minton.
Showers are expected again Saturday afternoon -- especially in the south metro areas.
The high Friday will be in the mid-90s.
