Recent National Weather Service and model guidance point to overnight radiative cooling under mostly clear skies and light winds, supporting a Seattle low near 50–52°F on September 19. Clear conditions favor efficient heat loss after daytime highs in the upper 60s to low 70s, while light southerly flow limits mixing with warmer marine air. Historical September averages near 52.5°F provide context, yet recent stable high-pressure influence has kept lows in the low 50s. Minor forecast spreads arise from potential increases in low-level moisture or variable cloud cover that could raise the minimum by 1–2°F, explaining the tight clustering of market-implied probabilities across the 50–55°F range. Updated model runs ahead of the date will refine these thresholds.

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 19 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 and model guidance point to overnight radiative cooling under mostly clear skies and light winds, supporting a Seattle low near 50–52°F on September 19.
