Latest National Weather Service guidance and consensus from GFS and ECMWF models place Atlanta's highest temperature on April 17 in the upper 80s, fueling trader consensus around 88-89°F (35% implied probability) and 86-87°F (30.5%). A persistent mid- and upper-level ridge over the Southeast enforces subsidence and ample sunshine, boosting peak insolation while southwesterly winds of 5-10 mph advect warm, humid air masses—yielding highs 10-15°F above the climatological April normal of 76°F. The narrow split reflects model spread on boundary-layer mixing depths and potential thin cirrus clouds, which could cap heating at 86-87°F or allow 88-89°F peaks. Next 12z runs today may resolve uncertainties before observations at Hartsfield-Jackson Airport.

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.
