**Forecast models from the National Weather Service and other agencies point to an overnight low in the low-to-mid 50s°F for Seattle on September 25, 2026, driven by a passing weather system bringing showers, southwesterly winds, and increased cloud cover that limits radiative cooling.** Recent model runs show temperatures dropping to around 47–52°F after evening rain, consistent with climatological norms near 51°F for the date while reflecting modest cooling from upstream marine air. Trader emphasis on the 52–53°F bin reflects this consensus range, with secondary positioning on cooler outcomes tied to potential heavier rainfall or clearer skies later allowing greater heat loss. Key resolution hinges on the official minimum recorded at Sea-Tac Airport between midnight and 6 a.m. PDT, with further model updates expected to refine probabilities before the period closes.

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 25 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.**Forecast models from the National Weather Service and other agencies point to an overnight low in the low-to-mid 50s°F for Seattle on September 25, 2026, driven by a passing weather system bringing showers, southwesterly winds, and increased cloud cover that limits radiative cooling.**
