**Current forecasts from the National Weather Service and other models indicate a low temperature near 72°F for Atlanta on September 11, 2026, amid a warm, humid pattern with daytime highs in the low 90s and showers likely.** This setup favors moderate overnight lows in the low 70s due to high dew points, limited radiational cooling under cloudy or stormy conditions, and a persistent southerly flow that prevents significant cold-air advection. Historical September averages place typical lows around 67°F, but the ongoing late-summer warmth has kept recent overnight minima elevated near 70–75°F. The market’s closely matched probabilities for extremes (65°F or below at 44% implied, 84°F or higher at 38.5%) reflect trader emphasis on forecast uncertainty: small shifts in cloud cover, storm timing, or steering patterns could allow greater cooling or suppress it. Upcoming model updates and short-range guidance will likely clarify whether the warm, moist boundary layer dominates or allows more nocturnal temperature drops.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Hartsfield-Jackson International Airport Station in degrees Fahrenheit on 11 Sep '26.
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.**Current forecasts from the National Weather Service and other models indicate a low temperature near 72°F for Atlanta on September 11, 2026, amid a warm, humid pattern with daytime highs in the low 90s and showers likely.**
