Recent National Weather Service and model guidance indicate an overnight low near 71–72°F for Atlanta on September 21 under partly cloudy skies with isolated thunderstorm chances after midday, keeping surface temperatures elevated compared with the 1991–2020 average low of 64°F. Light easterly winds and high humidity near 70–80% limit radiational cooling overnight, while any late-day cloud cover or scattered showers could further suppress the minimum by reducing outgoing longwave radiation. These conditions create tight clustering of market-implied odds across the 68–75°F bins, with traders weighing small forecast adjustments from GFS and NAM runs against the narrow historical range of September 21 minima. Updated NWS briefings and next model cycle will clarify whether modest cooling or persistent warmth shifts the distribution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
