Latest National Weather Service model guidance for Atlanta projects a daily maximum near 84–86°F today, driven by weak high pressure, light southwesterly flow, and partly cloudy skies that limit afternoon heating while keeping humidity moderate. This range aligns with the climatological May average high of 82–85°F at Hartsfield-Jackson Atlanta International Airport and the absence of strong frontal boundaries or moisture that could either suppress or enhance temperatures. Traders are therefore splitting probability between the 84–85°F and 86–87°F bins, reflecting small differences in model solutions for peak solar insolation and boundary-layer mixing. No major shifts in steering patterns are expected before evening, so the final observation from the official ASOS station will hinge on the precise timing of any cloud build-up or wind increase in the late afternoon.
