Latest National Weather Service guidance and ensemble model runs indicate Atlanta’s overnight low on September 20 will likely settle near 71 °F, supported by a persistent upper-level ridge and surface high that maintain warm, moist southerly flow. High dew points around 70 °F limit radiative cooling overnight, while scattered afternoon thunderstorms may introduce variable cloud cover that either caps daytime heat or traps warmth after sunset. This setup contrasts with the historical average low of 64 °F and explains why the market assigns roughly equal weight to sub-65 °F and 84 °F-plus outcomes: modest shifts in timing of any weak frontal boundary or thunderstorm outflow could alter the minimum by several degrees. Updated 12Z GFS and ECMWF runs plus the next NWS Atlanta forecast discussion will provide the clearest near-term signal.

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.
