**Clear skies and light easterly winds under high pressure are driving consensus for an overnight low in the upper 60s to low 70s on September 15 in Atlanta.** Official National Weather Service guidance and multiple model runs indicate radiational cooling after a sunny day with highs near 90–92°F, yielding lows around 69–73°F. Dew points in the upper 60s and minimal cloud cover support efficient heat loss after sunset, while light winds (5–10 mph) limit mixing that could keep temperatures higher. Historical September averages place the typical low near 66°F, but recent dry, stable conditions have kept overnight readings several degrees above that baseline. Trader sentiment remains split because small shifts in wind speed, humidity, or timing of clearing can move the minimum across bucket thresholds, with no major weather systems expected to alter the pattern before resolution.

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.
