Sunday morning, June 21, 2026, is starting out more like a scene from a mystery novel than a summer day, with thick fog and mist wrapped around Atlanta and Peachtree City. Visibility is reduced near Hartsfield‑Jackson, temperatures are parked in the low 70s, and the city is slow to wake. The sun is expected to punch through later this afternoon and send highs toward 88°F, with the usual summer caveat: late‑day pop‑up storms are possible, so it is smart to keep a light rain shell in the car if you have outdoor plans.
Foggy Morning, Slow Commute
Visibility has dropped to roughly a quarter mile in parts of the metro, and the low clouds and patchy fog are likely to keep drivers tapping the brakes on surface streets and around airport access roads early on. West to southwest winds should pick up to around 5–10 mph by midmorning, which will help lift the low clouds and clear the view as temperatures climb. For timing and more detailed updates, check in with the National Weather Service.
Afternoon Storm Chances
As the day heats up, the atmosphere gets just unstable enough for a slight chance of showers and thunderstorms this evening, especially after 5 p.m., with the best shot along and south of the I‑20 corridor. Most storms should be brief, but a few could drop heavy rain in a hurry and kick up some gusty winds that may slow the evening drive. If you are headed to a concert, a patio dinner, or anything else outdoors, it would not hurt to have a backup plan under cover or to move things earlier in the day.
Monday Heat and Strong Storm Risk
Warm air sticks around into Monday, June 22, as a stronger southwest flow pushes dew points higher and sends heat‑index values into the upper 90s to around 100°F in some spots. By late Monday afternoon and evening, forecasters expect scattered showers and thunderstorms to be more common, with the potential for stronger wind gusts and localized flash flooding. For background on this pattern, revisit our earlier look at the region turning into a weekend pressure cooker.
Plan Ahead
Hydrate, dress light, and try to avoid strenuous outdoor work in the peak afternoon heat if you can shuffle your schedule. If you are driving during the evening commute, build in some cushion for slowdowns from fog this morning or brief storms later. Conditions can change quickly, so keep an eye on the National Weather Service and local traffic reports before you head out.
