Trader consensus on Polymarket heavily favors a highest temperature of 74-75°F in Atlanta today at 50.5% implied probability, driven by the National Weather Service's latest forecast indicating highs in the low to mid 70s under a post-frontal airmass following a recent cold front passage that brought isolated showers yesterday. This cooler regime contrasts with climatological May 14 averages near 81°F, as northwesterly winds and lingering mid-level clouds limit daytime heating and convective mixing. Ensemble model guidance from GFS and ECMWF supports this range, with minimal divergence, though partial clearing could nudge toward 76-77°F (25.5%). Monitor hourly observations from Hartsfield-Jackson Atlanta International Airport, the market's resolution source, as afternoon sunshine may refine the peak amid low uncertainty for sub-80°F outcomes.
