This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 2 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest 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. In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. 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.
An approaching early-September Pacific storm system is the dominant driver behind trader positioning, with forecast models converging on cloudy skies, widespread rain, and south winds of 10-15 mph gusting to 25 mph that will limit daytime heating across the Puget Sound region. Official guidance from sources such as the National Weather Service places the September 2 high near 66°F, several degrees below the 1991-2020 climatological average of roughly 74°F, as thick cloud cover reduces incoming solar radiation and evaporative cooling from precipitation further caps temperatures. Recent model runs show tight clustering in the mid-60s, though minor variations in storm timing or intensity could shift the outcome by a degree or two; updated NWS forecasts and next model cycles tomorrow morning represent the key near-term catalysts for any market movement.
