This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 30 Aug '26. The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksea This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent National Weather Service and ensemble forecasts indicate a Sunday night low in the lower to mid-50s°F at Seattle-Tacoma International Airport, driven by persistent marine layer influence and light onshore flow that moderates overnight radiational cooling. Current observations show lingering clouds and showers from a weak frontal passage, with dew points near 52°F limiting further temperature drops. This setup aligns with historical August climatology near 56°F but favors the cooler side amid above-average regional humidity. Updated model runs tonight and tomorrow morning will refine the exact minimum before resolution.
