Recent National Weather Service guidance and ensemble model runs point to a building subtropical ridge over the Southeast driving Atlanta’s June 28 maximum into the low-to-mid 90s, with dew points in the low-to-mid 70s supporting heat indices near or above 100 °F. Scattered afternoon convection tied to weak shortwave energy and modest mid-level moisture could cap surface heating and shave a degree or two from the daily peak, keeping the distribution centered on the 90–93 °F bins that together command over two-thirds of market-implied probability. Historical June climatology shows a 93 °F normal high, but recent soil moisture from prior rains and variable boundary-layer mixing introduce the narrow spread between the leading 92–93 °F (38.5 %) and 90–91 °F (29.0 %) outcomes. Updated model cycles and the 18Z NWS forecast discussion expected later today will be the next catalysts for any shift in trader positioning.
