Recent National Weather Service forecasts and observational data position the 68–71°F range as the clear market leader, with trader consensus assigning 80% combined implied probability to those bins. Persistent marine layer clouds, light southerly winds, and a slight chance of drizzle have limited daytime heating on September 7, keeping readings below the 72.6°F September 7 climatological normal. Model guidance and real-time surface observations show peak temperatures most likely near 69°F, consistent with the dominant 70–71°F (45%) and 68–69°F (35%) outcomes. Updated afternoon NWS briefings and any late-day clearing could provide the final data points for market resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
