Trader consensus on Polymarket reflects tight uncertainty in National Weather Service guidance for Atlanta's March 28 high temperature, with ensemble model runs from GFS and ECMWF clustering around 68-71°F amid mild southerly flow and partial cloud cover. The closely matched 28.5% implied probabilities for 68-69°F and 70-71°F stem from subtle differences in peak afternoon insolation and boundary layer mixing, as light winds (5-10 mph) transport warmer Gulf moisture while high pressure overhead suppresses extremes. Historical March norms (average high ~66°F) support this range, but diurnal temperature variability and any convective timing could nudge outcomes toward 72-73°F (17.5%). New 00z model updates expected overnight may refine the spread before resolution.

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.
