National Weather Service forecasts for Atlanta point to a high near 86°F on May 16 under mostly sunny skies with strong solar heating and efficient boundary-layer mixing that favors peak readings in the mid-80s. These conditions position the 84–87°F range as the clear market leaders, reflecting trader consensus on typical late-spring variability where afternoon convection or scattered high clouds could trim a degree or two from maximums. Model guidance from GFS and ECMWF shows close alignment on this outcome, exceeding the climatological May average high of roughly 82°F, while any delay in mixing or isolated showers would shift probabilities toward the lower end of the leading bins. Updated soundings and afternoon observations will refine the final reading measured at Hartsfield-Jackson Atlanta International Airport.
