Trader consensus heavily favors 84-85°F (64%) as Atlanta's highest temperature on March 21, driven by the latest NOAA Weather Prediction Center guidance and ensemble model outputs from GFS and ECMWF, which converge on peak highs in this range amid a strong upper-level ridge fostering southerly flow and adiabatic warming. Recent 12z model runs have sharpened this outlook, nudging probabilities up from broader 82-87°F clusters seen 48 hours ago, while ruling out cooler outcomes below 80°F given persistent drought conditions suppressing cloud cover and enhancing solar insolation. Historical March 21 norms hover around 66°F, but this anomalously warm setup—fueled by a positive temperature anomaly—positions 86-87°F (14%) as the next likeliest, with extremes above 90°F improbable per verified soundings and dewpoint data.

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.
