Recent National Weather Service forecasts and supporting model guidance point to clear to partly cloudy skies and light winds overnight into September 18, favoring radiative cooling within a mild air mass and producing minimum temperatures in the low to mid-50s across the Seattle area. This aligns closely with mid-September climatological averages near 52–53 °F at Sea-Tac, where high pressure has maintained dry conditions after earlier warmth. The resulting market-implied odds heavily favor the 54–55 °F bin at 56 %, with 52–53 °F as the next most probable outcome, reflecting trader assessment of limited downside risk absent stronger onshore flow or cloud cover that could moderate the overnight low. Updated model runs and the evening NWS briefing remain the key near-term catalysts.

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.
