The rain that swept into metro Atlanta early Tuesday afternoon moved through quickly, leaving rush-hour drivers with what looked to be a calm evening commute.

But the threat of showers and possibly thunderstorms with localized heavy rain remained a possibility later in the night as they move into the area from the north, Channel 2 Action News meteorologist Brad Nitz said.

The late afternoon calm seemed to be helping air travelers, too. Delays at Hartsfield-Jackson International Airport continued through the day, but were less than 15 minutes for departures and up to a half hour for arrivals.

What would likely be isolated storms Tuesday night could reach the area around 8 or 9 p.m. The off-again, on-again nature of the summer storms is expected to continue into Wednesday, although the chance for rain drops to 40 percent before kicking back up on Thursday. And there will be the chance of storms into the holiday weekend as well.

High temperatures are expected to reach into the upper 80s most the week to near 90 on the weekend.

Warm and humid conditions are forecast for Saturday morning’s AJC Peachtree Road Race.
