NWS Atlanta: warming trend, daily storms, triple-digit heat index midweek

ATLANTA — Summer is not done negotiating.

The National Weather Service office in Peachtree City highlighted a familiar late-summer package for north and central Georgia: gradually warming temperatures, continued daily chances for showers and thunderstorms over the next several days, and heat index values likely returning to triple digits by the middle of next week — especially across portions of central Georgia.

Sunday’s working forecast

Point forecasts for Atlanta-area grids on weather.gov late Saturday called for a mostly sunny to partly sunny Sunday with highs near the lower 90s and a chance of afternoon showers and thunderstorms — generally in the 20–40 percent range depending on exact metro location — then a slight chance of storms Sunday night with lows in the low-to-mid 70s. Those percentages are not a guarantee of widespread soaking rain; they are a signal to keep outdoor plans flexible after lunch.
