Current National Weather Service and private model guidance points to a high temperature in the mid-80s for Atlanta on May 16 under mostly sunny skies and light southwesterly flow, placing the 84–85°F and 86–87°F bins in near parity. Subsidence from a building ridge and modest dew-point recovery are expected to support daytime warming, while any afternoon cumulus development or slight steering shifts could cap the peak near 85°F or allow a brief push into the upper 80s. Historical May climatology shows average highs near 82°F with standard deviations of 4–5°F, so the market’s tight spread reflects remaining uncertainty in boundary-layer mixing and exact insolation before tonight’s data updates.
