**Recent National Weather Service forecasts and observational data positioned the overnight low in Seattle on September 18 near 56–57°F as the consensus outcome.** Clear skies and light winds under building high pressure promoted radiative cooling after a daytime high near 70°F, with dew points holding around 52°F that limited further temperature drops. This aligned with typical late-September patterns influenced by onshore marine flow, keeping the low above the 1991–2020 climatological average of 52.6°F but consistent with recent model runs projecting mid-50s readings. Preliminary station reports and short-range guidance reinforced trader confidence in the 56–57°F bin at 90% implied probability, while the slim 0.5% on 54–55°F reflected minimal expected deviation. Official NWS climatological summaries expected in coming days will confirm the precise minimum for market 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 18 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 forecasts and observational data positioned the overnight low in Seattle on September 18 near 56–57°F as the consensus outcome.** Clear skies and light winds under building high pressure promoted radiative cooling after a daytime high near 70°F, with dew points holding around 52°F that limited further temperature drops.
