Recent National Weather Service guidance and ensemble model runs indicate overnight lows in Seattle on September 12 will likely settle in the mid-50s°F amid increasing onshore marine flow and an upper-level trough deepening offshore. This setup favors persistent cloud cover that limits radiational cooling while light winds and higher humidity moderate temperature drops, keeping the daily minimum near the 1991–2020 climatological average of 53.7°F. Trader sentiment remains split because small forecast adjustments in dew points, wind speed, or cloud thickness could easily shift the low by a few degrees either side of 55°F, with 47°F or below and 66°F-plus both carrying meaningful implied probability. Updated short-range model runs and NWS briefings through early Friday will provide the next key data points ahead of 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 12 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 model runs indicate overnight lows in Seattle on September 12 will likely settle in the mid-50s°F amid increasing onshore marine flow and an upper-level trough deepening offshore.
