**Current National Weather Service and private model consensus points to a high near 81°F in Atlanta on September 26 under mostly sunny to partly cloudy skies with light winds and negligible rain chances.** This aligns closely with the market's strongest outcome at 80-81°F (46.5% implied probability), as a cooler, drier Canadian airmass has settled in behind recent frontal passage, producing subsidence and seasonable early-fall temperatures. High pressure and clear conditions favor efficient daytime heating without excessive warmth, keeping readings from climbing much above the low 80s. Recent runs show minimal spread, with most guidance clustered between 79–82°F. Historical late-September averages near 80–81°F provide additional context for the tight distribution around the 80-83°F range that dominates trader positioning. New NWS forecast updates and any late-model adjustments over the next 24–48 hours represent the primary variables that could shift probabilities if unexpected cloud cover or a stronger ridge develops.

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 26 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.**Current National Weather Service and private model consensus points to a high near 81°F in Atlanta on September 26 under mostly sunny to partly cloudy skies with light winds and negligible rain chances.** This aligns closely with the market's strongest outcome at 80-81°F (46.5% implied probability), as a cooler, drier Canadian airmass has settled in behind recent frontal passage, producing subsidence and seasonable early-fall temperatures.
