Persistent afternoon thunderstorm risks across Atlanta's late-summer conditions have already prompted preferred lies in early rounds at East Lake Golf Club and kept the PGA Tour's on-site meteorologist active, creating trader balance around a potential delay on the final round. Forecasts show scattered storms and lightning chances most afternoons through Saturday, with Sunday's outlook improving to partly sunny skies but still carrying 20-50% rain probability concentrated later in the day. The pop-up nature of these cells, combined with humid 80s temperatures and soft course conditions from prior precipitation, sustains uncertainty over whether play finishes without interruption. Confirmed lighter winds reduce some variability, yet any lightning within striking distance or heavy downpours could trigger suspensions that extend into evening, while a clear window would favor completion on schedule.
