This market will resolve to the temperature range that contains the highest temperature recorded at the Hartsfield-Jackson International Airport Station in degrees Fahrenheit on 18 Apr '26. 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.Trader sentiment clusters around 86-89°F outcomes at over 60% combined implied probability, reflecting the latest National Weather Service forecasts and ensemble model guidance from GFS and ECMWF projecting Atlanta's high on April 18 near 87°F under a persistent upper-level ridge fostering sunny skies and efficient afternoon heating. The razor-thin edge for 86-87°F over 88-89°F stems from subtle model divergences: GFS ensembles leaning slightly cooler due to marginally stronger boundary-layer mixing limits, while ECMWF runs hint at enhanced warm-air advection from the south potentially nudging peaks higher. This follows March 2026's second-warmest on record and early April highs averaging 84-85°F above climatological norms of 73°F. New 12z model runs and NWS updates today could sharpen resolution amid inherent short-range forecast uncertainty.
