Current forecasts from the National Weather Service and other models indicate overnight lows near 72–73°F for Atlanta on September 11 amid southerly flow and increasing Gulf moisture, supporting the tight clustering of market-implied probabilities around mid-70s and both extremes. Persistent high pressure offshore and a developing low to the west are sustaining above-normal warmth and humidity while limiting radiational cooling, with scattered thunderstorms expected to add cloud cover that could further moderate temperature drops. This setup contrasts with the 1991–2020 climatological average low of roughly 67°F for the date and explains why traders assign comparable weight to bins above 84°F versus 65°F or below. Fresh model runs and updated National Weather Service briefings over the next 24 hours will likely refine the exact minimum 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.
