This market will resolve to the temperature range that contains the highest temperature recorded at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 10 May '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 Seattle-Tacoma International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/wa/seatac/KSEA. 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.National Weather Service observations at Seattle-Tacoma International Airport (KSEA), the official station for resolution via Weather Underground, confirm the highest temperature on May 10 reached 66-67°F under partly cloudy skies with light northerly winds, driving trader consensus to a 100% implied probability for this outcome. This matched pre-event forecast model consensus projecting highs near 66°F amid typical May marine layer influence and cool Pacific air masses, consistent with Seattle's climatological average high of 66°F. Scenarios that could realistically challenge this include rare post-preliminary data revisions from sensor calibration issues or quality control audits by NOAA, though such adjustments occur infrequently for established readings.
