Metro Atlantans awakened Wednesday to the coolest temperatures in more than three months, as the mercury dipped well into the 50s in some areas.

Atlanta’s official low at Hartsfield-Jackson International Airport dropped to 60 degrees for the first time since May 23.

Elsewhere, it was 56 degrees in Dunwoody and Alpharetta, 57 in Cartersville and 58 in Marietta and Peachtree City.

Channel 2 meteorologist Karen Minton said morning lows will be a little warmer the rest of the week, bottoming out around 67 early Thursday and 69 Friday.

Afternoon highs will be in the mid-80s under mostly sunny skies through Friday, Minton said.

“Saturday and Sunday, rain chances are going up, but all bets are off when we take into account Tropical Storm Erika,” Minton said. “Depending on where it goes, it could change our forecast down the road.”

For now, Minton is predicting a 30 percent chance of rain on Saturday, increasing to 40 percent Sunday, with highs in the mid-80s and lows in the low 70s.

The National Weather Service office in Peachtree City said Wednesday that Tropical Storm Erika could impact parts of Georgia early next week with gusty winds and heavy rain.

The National Hurricane Center’s forecast puts the storm near the southeast Florida coast early Monday and in northern Florida by Tuesday.
