Recent National Weather Service and ensemble model guidance points to a minimum temperature of 54–55°F in Seattle on September 8, aligning with the market's leading 39% implied probability. Clear skies under high pressure, light northerly flow, and radiational cooling overnight are expected to produce dew points near 12–13°C with minimal cloud cover or marine influence to moderate temperatures. This matches the long-term average low of 54.4°F for the date and follows recent observations of 52–57°F minima amid stable early-September conditions. Model spread introduces modest uncertainty, supporting the 25–30% probabilities assigned to both cooler (50–53°F) and warmer (56°F+) bins, though no major forecast shifts have occurred in the past 48 hours. Updated runs and official NWS briefings ahead of the overnight period will provide the next key data points for resolution.

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 8 Sep '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.
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.Recent National Weather Service and ensemble model guidance points to a minimum temperature of 54–55°F in Seattle on September 8, aligning with the market's leading 39% implied probability.
