National Weather Service forecasts for Atlanta on September 20 project a daytime high in the upper 80s to low 90s, driven by moderating easterly flow, increasing afternoon cloud cover, and a 40-60% chance of showers and thunderstorms that could cap peak readings. Recent model runs show consistency around 88-91°F, aligning with trader emphasis on the 90-91°F outcome at 40.5% implied probability, followed by 88-89°F. This positioning reflects typical late-September climatology where daytime heating competes with convective cooling, though any delay in storm development could push readings slightly higher within the favored bins. Updated NWS guidance and short-range model trends remain the key near-term catalysts.

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 20 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.National Weather Service forecasts for Atlanta on September 20 project a daytime high in the upper 80s to low 90s, driven by moderating easterly flow, increasing afternoon cloud cover, and a 40-60% chance of showers and thunderstorms that could cap peak readings.
