Trader consensus on Polymarket tilts toward a high of 62-63°F in Atlanta on March 24 (29% implied probability), driven by the National Weather Service's latest forecast projecting a daytime maximum near 62°F under partly cloudy skies with northwest winds ushering in cooler Canadian air behind a weak cold front. This edges out 64-65°F (24.5%) as ensemble models like GFS and ECMWF show a tight spread, with slight ensemble mean bias toward the low 60s due to lingering upper-level troughing over the Southeast suppressing temperatures below March climatological norms of 67°F. Differentiating factors include frontal timing uncertainty—earlier passage favors 62-63°F, while delay could lift highs to 64-65°F—and diurnally driven boundary layer mixing, with key updates from 12Z model runs expected to refine odds ahead of resolution.
