This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Hartsfield-Jackson International Airport Station in degrees Fahrenheit on 30 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=katl This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. 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.
Forecast consensus from the National Weather Service and supporting models points to a mostly sunny day on August 30 with light easterly winds, supporting a high near 90–91°F in Atlanta. This aligns with the market’s leading 90-91°F bin at 59.5% implied probability, as multiple sources including the NWS Peachtree City office and ensemble guidance converge on that range without major model spread or incoming fronts that would sharply alter temperatures. Late-August climatology in Atlanta features average highs around 87°F, but recent conditions show elevated readings, with multiple 95–98°F days earlier in the month under similar high-pressure setups. Minimal cloud cover and dew points in the low 70s are expected to allow efficient daytime heating, while the absence of significant moisture or convective activity keeps the focus on thermal factors rather than storm-related cooling. Updated NWS products issued August 29 reinforce the 89–91°F window, with only modest upside risk if insolation exceeds expectations or minor model adjustments occur overnight. Traders appear to weight the official forecast heavily, reflected in the sharp drop-off beyond 92–93°F (11.5%) and negligible probabilities for outcomes below 88°F. The next key data points are the morning model runs and any revised NWS discussion on August 30, which could confirm or nudge the final observed high before markets resolve.
