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 3 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 that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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 upper-level low drifting south from the Gulf of Alaska, paired with an associated cold front, is driving cooler-than-average conditions across the Pacific Northwest and keeping Seattle’s September 3 high in the mid-60s. Official National Weather Service guidance and short-range model consensus point to highs in the lower to mid-60s under partly sunny skies with scattered showers, reflecting suppressed temperatures from the cool marine air mass and limited daytime heating. Historical climatology shows an average high near 74 °F, underscoring how this synoptic pattern deviates from typical early-September warmth. The tight split between the 64–65 °F (41.5 %) and 66–67 °F (45 %) bins reflects minor model differences in cloud cover, wind direction, and the precise degree of post-frontal warming that will determine which two-degree window captures the official high.
