Recent National Weather Service guidance and ensemble forecasts indicate the lowest temperature in Seattle on September 24 will likely occur overnight into the early morning under increasing cloud cover ahead of a frontal system, with model consensus centering on 52–53°F. Marine air influence and expected rain later in the period limit radiative cooling compared to clearer conditions, while light northerly winds and higher humidity further moderate the minimum. Historical September averages near 51–52°F provide context, yet the current setup favors values clustered around the 52–53°F bin that leads market-implied odds. Minor forecast shifts in cloud timing or precipitation onset could push readings into adjacent ranges such as 50–51°F or 54–55°F.

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 24 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 guidance and ensemble forecasts indicate the lowest temperature in Seattle on September 24 will likely occur overnight into the early morning under increasing cloud cover ahead of a frontal system, with model consensus centering on 52–53°F.
