Latest National Weather Service forecasts and ensemble model runs from NOAA indicate a high-pressure ridge dominating the Southeast, steering warm air advection from the Gulf of Mexico toward Atlanta on March 27, supporting market-implied odds clustered in the low-to-mid 80s°F with 84-85°F leading at 34%. Trader consensus reflects subtle model differences: the GFS ensemble leans slightly warmer toward 86-87°F (19% odds) due to enhanced subsidence drying, while the ECMWF favors 82-83°F (26%) amid potential mid-afternoon cloudiness from upstream convection. Diurnal heating under mostly sunny skies could push boundaries, but inherent forecast uncertainty from boundary layer mixing and timing of any weak disturbances differentiates these tight outcomes. New 12z model updates expected soon may sharpen the signal.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Hartsfield-Jackson International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ga/atlanta/KATL.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
