This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Hartsfield-Jackson International Airport Station in degrees Fahrenheit on 19 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Hartsfield-Jackson International Airport Station, available here: https://www.wunderground.com/history/daily/us/ga/atlanta/KATL. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Forecasts from the National Weather Service (NWS), AccuWeather, and numerical models converge on a daily maximum near 94–96°F for Atlanta on August 19, 2026. This range sits 5–8°F above the late-August climatological average of ~89°F, reflecting persistent above-normal warmth across the Southeast driven by a strong subtropical ridge, abundant solar insolation under mostly clear skies, and light northwest winds that limit mixing and allow efficient daytime heating. Recent model runs and official guidance have shown little shift over the past 24–48 hours, with only minor spread between solutions (some ensembles briefly hinting at 97°F if boundary-layer mixing stays suppressed). The absence of significant cloud cover, precipitation, or a frontal passage keeps the upper end of the distribution limited, while the strong consensus around mid-90s explains why the 94–95°F bin holds the highest market-implied probability (53%). Traders appear to be weighting the latest NWS and high-resolution guidance most heavily, with the 92–93°F and 96–97°F outcomes capturing residual uncertainty in exact peak timing and local heat-island effects.
