**National Weather Service forecasts for Seattle on September 13, 2026, center the daily minimum near 54–56°F amid a Pacific weather system delivering morning showers, increasing clouds, and southerly flow that limits overnight radiational cooling.** This aligns closely with the 1991–2020 climatological average low of 53.5°F for the date while reflecting the current setup of modest onshore moisture and temperatures running near or slightly below seasonal norms. Model consensus shows little deviation expected before the minimum occurs, keeping the 54–55°F bin dominant in trader positioning; lower outcomes remain improbable absent an unexpected clear-sky surge or stronger cold advection, while warmer bins sit well outside the guidance envelope. Updated short-term model runs and NWS briefings through the evening will provide the final resolution data.

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 13 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.**National Weather Service forecasts for Seattle on September 13, 2026, center the daily minimum near 54–56°F amid a Pacific weather system delivering morning showers, increasing clouds, and southerly flow that limits overnight radiational cooling.** This aligns closely with the 1991–2020 climatological average low of 53.5°F for the date while reflecting the current setup of modest onshore moisture and temperatures running near or slightly below seasonal norms.
