Current forecasts from NOAA and regional models indicate a Seattle overnight low near 57–60°F under partly cloudy skies with light southwest winds and moderate marine-layer influence, supporting clustered probabilities around 58–61°F while the close 44% odds on 68–69°F and 72°F+ reflect residual uncertainty in radiative cooling rates. Key differentiating factors include variable cloud cover that can suppress or enhance nighttime temperature drops, dew-point depression tied to humidity levels, and weak pressure gradients limiting mixing; any increase in onshore flow or unexpected clear periods could shift the minimum several degrees. With resolution dependent on official station observations, traders are weighting the latest model runs and mesoscale updates heavily as the day progresses.

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 23 Aug '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
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Current forecasts from NOAA and regional models indicate a Seattle overnight low near 57–60°F under partly cloudy skies with light southwest winds and moderate marine-layer influence, supporting clustered probabilities around 58–61°F while the close 44% odds on 68–69°F and 72°F+ reflect residual uncertainty in radiative cooling rates.
