Recent NWS and model guidance for Seattle shows overnight lows on September 21 centered near 52–54°F under a weak ridge with light northerly flow, patchy fog, and clear skies favoring radiational cooling after sunset. Local variations in marine layer depth and urban heat retention create the tight spread among 48–53°F bins, where small shifts in dew-point depression or wind speed could alter the minimum by 2–4°F. Historical climatology places the September 21 average low at 52°F, providing a baseline against which current ensemble runs show modest negative anomalies. Updated model cycles and any revised NHC or local office briefings over the next 48 hours remain the key catalysts for price movement ahead of the market’s resolution window.

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 21 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 NWS and model guidance for Seattle shows overnight lows on September 21 centered near 52–54°F under a weak ridge with light northerly flow, patchy fog, and clear skies favoring radiational cooling after sunset.
